What’s Actually Staining Your Roof and What to Do About It

After a long, humid summer, it’s not unusual to notice dark streaks on your roof or a few green patches.

And if you look around, you’re likely to see it on your neighbors’ roofs as well. Staining is one of the most common issues homeowners in our humid, coastal Virginia climate have with their roofs. But before you climb up a ladder to take care of it yourself or pay someone a bunch of money to clean it up for you, let’s dive more deeply into what it is, how it affects your roof, and the best way to deal with it.

What exactly is it?

Roof staining usually comes from one of three things, and it’s common to have more than one at the same time.

Dark streaks. These are the black or brownish stripes that look like soot or dirt running down the roof. They’re typically caused by cyanobacteria, which most people (and most roofers) simply call algae. Early on, this is mostly a cosmetic issue.

Green, fuzzy patches. This is moss. It tends to grow in thick cushions, usually in shaded spots or along the lower edges of the roof. Moss behaves differently than streaking because it holds moisture against the roof surface.

Flat, crusty spots. Gray, green, or orange patches that look almost painted onto the shingles are lichen. They hold on tightly and grow slowly, which makes them harder to remove than the other two.

You don’t need to identify each one perfectly to know what to do next. What matters is how long it has been there and whether it has started affecting the shingles underneath.

Why Hampton Roads roofs are so impacted

Our region is the perfect place for these organisms to live and thrive. Humidity stays high for much of the year. We get regular rain and heavy morning dew. Winters are mild enough that growth never fully stops. And between the mature oaks and pines, plenty of roofs spend part of the day in shade, which slows drying.

Wind plays a role too. Spores travel from roof to roof, which is why staining often seems to move through an entire neighborhood. Homes near the water or marsh, where the air stays damp longer, tend to see it sooner and more heavily.

All that said, you may look around and see half the houses in your neighborhood show signs of this staining, and half don’t. Two houses on the same street can look very different for a few reasons:

  • Shingle makeup. Many asphalt shingles contain limestone filler, which these organisms can feed on.
  • Sun exposure. Shaded slopes, and often the north-facing side, stay damp longer and show growth first.
  • Color. Streaks are much more obvious on light-colored roofs than on dark ones, even when the growth is similar.
  • Material. Metal roofs are far more resistant, though growth can still collect in shaded valleys and around laps.

Does the staining really matter?

The honest answer depends on how long it has been there and what’s growing. Dark streaking by itself rarely causes leaks. It affects curb appeal, and in some neighborhoods, it can draw attention from the HOA. Dark streaks also absorb a bit more heat than a clean roof, though the effect on your energy bills is small.

Moss and lichen are a different story over time. Moss can lift the edges of shingles and let water work its way underneath. Growth that sticks around for years can contribute to granule loss, which shortens the life of the shingles. While none of this is going to destroy your roof overnight, it’s also not a great idea to ignore it for years on end.

Signs the problem has gone beyond surface staining:

  • Shingles that are curling, lifting, or cracking
  • Bare or thinning spots where granules have worn away
  • A noticeable amount of granules collecting in your gutters or at the downspouts
  • Soft or spongy areas found during a roof inspection
  • Water stains on ceilings or in the attic

If any of those sound familiar, it’s time to have a roofer take a look.

Preventing roof staining

Prevention is where homeowners have the most control as well as the most options, depending on your home’s specific scenario. Here are a few ways to combat the stains.

Algae-resistant shingles. Many manufacturers build copper-containing granules into their shingles to discourage growth. If you’re planning a roof replacement, ask about this option. Algae resistance warranties are typically limited to a set number of years and vary by manufacturer, so understand the details.

Copper or zinc strips. Installed along the ridge, these strips release trace metal ions when it rains. The ions wash down the roof and discourage growth. They protect the area below them best, so long roof slopes may not see the benefit all the way to the edge.

Trim back the trees. More sunlight and airflow mean a faster-drying roof. Cutting back overhanging branches also reduces the debris that holds moisture against the shingles.

Keep water moving off the roof. Clogged gutters let water sit at the roof edge, which is exactly where moss likes to start.

Can you clean it?

Plenty of homeowners want to simply wash it off, but it’s not always that simple.

High-pressure washing is hard on shingles. It can strip away the granules that protect the roof and may affect your warranty. The gentler option is soft washing, which uses low pressure and a roof-safe cleaning solution. It’s best left to a company that cleans roofs regularly. DIY attempts with bleach and a ladder can damage landscaping, stain siding, corrode metal, and put you at risk on a wet, slick surface.

It’s also worth noting that while cleaning removes what’s there now, it doesn’t stop it from coming back. Without a prevention step, the growth usually returns.

When to call a roofer

If you’ve noticed staining on your shingles, but everything else looks and seems OK, you likely have time to plan. Trimming trees, clearing gutters, and finding a reputable roof cleaner is a reasonable place to start.

If the growth has led to damage, like lifted shingles, worn spots, or leaks, that’s where a licensed roofing contractor needs to come in. At Andrews Roofing, we handle roof repairs and replacements due to a variety of issues and are familiar with those most common in Hampton Roads. If you’re due for a new roof, we’re happy to talk through options that can help keep this from happening again, so contact us today.

How Your Roof Structure Affects an Attic Conversion

If you’ve been eyeing that empty or underused attic space and picturing a bonus room, home office, or guest suite, you’re not alone. A lot of the older homes here in Hampton Roads, especially in neighborhoods like Ghent, Larchmont, and Olde Towne, come with large attics that feel like they’re just waiting to be finished. High ceilings, decent floor space, sometimes even a window or two already in place.

But before those home improvement daydreams get carried away, you have to ask the most important question: can your roof structure actually handle it?

Most homeowners plan an attic conversion (in their head) around square footage and personal design. They consider where the couch goes, how much natural light you’ll get, whether there’s room for a closet. What often gets overlooked is the structure holding all of that up. If you don’t consider this first, the read of the project is already gridlocked.

What “Roof Load” Actually Means

When we talk about roof load, we’re really talking about two different things: dead load and live load.

Dead load is the weight of the structure itself. The framing, the sheathing, the shingles, the insulation. It’s fixed and it’s already accounted for in how your roof was originally built.

Live load is everything that gets added on top of that. Furniture, people walking around, storage boxes, and in some parts of the country, snow. Here in Hampton Roads, snow load isn’t much of a factor, but wind load is. Our roofs are engineered with nor’easters and hurricane season in mind, and that affects how trusses and rafters are designed and spaced.

Here’s the important part: most attics are framed for minimal live load. They’re built to hold some stored boxes and holiday decorations, not a bed, a dresser, and a person walking around on a daily basis. Converting that space into a livable room means the structure needs to handle a lot more weight than it was originally designed for.

Trusses vs. Rafters

Before anything else gets planned, you need to know how your roof is actually framed.

If your home has a truss-framed roof, which is common in newer construction, you’re working with an engineered system of webbing and supports that’s designed as a single unit. Cutting into or removing parts of that webbing to open up attic space usually isn’t possible without a full structural redesign. Trusses aren’t meant to be altered casually, and doing so can compromise the entire roof.

If your home has a rafter-framed roof, which is more common in older Hampton Roads homes, you’ve got more flexibility. Rafters leave the attic more open to begin with, but that doesn’t mean the existing joists were built to support a finished, livable floor. Reinforcement is usually still necessary.

This is the point where a roofer or structural engineer needs to get involved, before a contractor starts framing walls or running electrical. Figuring out what you’re working with structurally should come before any of the fun design decisions.

Signs Your Existing Structure May Need Reinforcement

A few things worth checking, or having a professional roofing contractor check, before you get too far into planning:

  • Sagging ridge lines or a floor that feels bouncy when you walk across the attic
  • Joists that look undersized or are spaced further apart than you’d expect
  • Existing water damage or rot, which can already be weakening the framing without being obvious
  • Ductwork, plumbing stacks, or electrical already running through the space, which can limit how much room you actually have to work with

If you notice any of these, it doesn’t mean the conversion is off the table. It just means reinforcement needs to be part of the plan from the start rather than something that comes up as a surprise mid-project.

What the Reinforcement Process Usually Looks Like

Depending on what your roof needs, reinforcement can look like sistering the existing joists (adding a new joist alongside the old one for extra support), adding a support beam, or in some cases a more involved re-engineering of the roof structure.

This typically means coordination between a roofer, a structural engineer, and your general contractor. It’s essentially never a one-person job because most localities here in Hampton Roads, including Virginia Beach, Chesapeake, Norfolk, Suffolk, and Portsmouth, will require engineered plans before permitting an occupied attic space. That may sound overwhelming, but it’s doable, and plenty of contractors have engineers on call who do this type of work for them regularly. It’s a good checkpoint that helps make sure the finished room is safe and built to last.

How Your Roof Is Involved

You might think of an attic conversion as primarily an interior project, but the roof itself is deeply involved in almost every part of it.

Converting an attic changes how air moves through your home, which means your existing ventilation setup often needs to be reevaluated. You can read more about why ventilation is so important in one of our past blogs, but just remember it’s one of the most critical systems in your home and cannot be overlooked without risking moisture damage or costly inefficiency.

Skylights and dormer windows, both common additions in attic conversions, mean new penetrations in your roof. Every one of those needs proper flashing and waterproofing to make sure you’re not trading a finished bonus room for a future leak.

Start Your Conversion Out on the Right Foot

We don’t say all of this to scare homeowners away from an attic conversion. Plenty of Hampton Roads homes have the bones for a great bonus room, home office, playroom or guest space. The key is getting the structural piece right from day one, before walls go up or before you fall in love with an idea that your roof can’t actually support.

If you’re considering an attic conversion and want to know what your roof structure can handle, contact Andrews Roofing today. We’ll take a look and help you figure out what’s possible before you get too far into planning.

Navigating Hampton Roads HOA Rules Before You Replace Your Roof

If you live in a community with a homeowners association, replacing your roof involves more than picking a shingle you like and scheduling a crew.

Across the Tidewater region, plenty of neighborhoods have architectural guidelines that govern what your new roof can look like and skipping that step can cost you far more than a fine. Here’s what tends to be true across Hampton Roads HOAs, and what to check before you get too far into planning.

Get Approval Before Work Begins

Virginia’s Property Owners’ Association Act gives HOAs the authority to set design guidelines for exterior changes, and roof replacement almost always falls under that umbrella. What catches homeowners off guard is the order of operations. Even when you’re covering the full cost of your own roof, many associations require sign-off from an architectural review committee before a single shingle comes off. It’s easy to assume that because you’re the one paying for it, it’s your call. In HOA communities, it usually isn’t, at least not entirely.

What guidelines typically cover

Every community writes its own rules, but a few categories show up again and again:

  • Color, often specified as an approved color family rather than one exact shade
  • Material type, with architectural shingles frequently required over older three-tab styles
  • Specific product lines or manufacturers, in communities with an approved materials list
  • Contractor qualifications, occasionally requested as part of the approval submission

The guidelines have to be written down somewhere and available to homeowners. If you’re not sure what applies to your property, you can request a copy of your governing documents, and Virginia law generally requires associations to provide them within a set window after a written request, commonly cited as ten to thirty days.

Skipping Approval Can Be a Big Risk

The coastal exposure Hampton Roads communities have raises the stakes for HOA paperwork. Because we sit in a higher wind and hurricane risk zone, some communities’ guidelines have requirements for wind rating or impact resistance in addition to color and material. That means a homeowner focused purely on aesthetics could choose a shingle that looks approved but doesn’t actually meet the association’s performance standard, which is an easy thing to miss if you’re not reading the fine print.

And the consequences of skipping the process aren’t limited to a sternly worded letter or dirty looks from the HOA President. If a finished roof doesn’t match what was approved, whether that’s the wrong color, the wrong material, or simply a case of never submitting for approval at all, an HOA can require the homeowner to redo it and bring it into compliance at their own expense. Nobody wants to pay for two roofs, plus the fines and potential liens that can pile up if it drags out.

The Historic Layer

A quick note for homeowners in parts of Norfolk and Portsmouth: some neighborhoods, like Ghent, Colonial Place, and Olde Towne, fall under historic district overlays that add a separate layer of review beyond a standard HOA. That’s a bigger topic on its own, and one we’ll cover in more depth in a future post, but if your home sits in one of these areas or another historic neighborhood, it’s worth knowing that HOA approval and historic district approval aren’t always the same conversation.

Start with the paperwork, not the shingles

Before you call a roofer, pull your HOA’s governing documents and look for the sections on exterior modifications, roofing materials, and the architectural review process. Having that information ready when you request a quote means your contractor can spec out a proposal that’s actually approvable, rather than submitting something that gets sent back and delays your project by weeks.

If you’re planning to sell down the road, this step matters even more. Virginia requires HOAs to include architectural guidelines and any approvals on file in the resale disclosure packet, so a roof that was never properly approved can become an ugly surprise at closing.

At Andrews Roofing, we’ve walked plenty of Hampton Roads homeowners through this process, and we’re happy to help you figure out what your HOA needs before we dive into the details. Contact us today to get started.

What to Do When a Tree Hits Your House

We hope it never happens, but in Hampton Roads, where wooded lots are as plentiful as the pop-up storms, tropical system and nor’easters we experience, it’s never out of the question. There may come a day when you’re awoken in the middle of night to the unmistakable “thud” of a tree landing on your roof. As jarring as that moment can be, the real anxiety is usually in the follow up. Who do you call first? What can you do yourself and what should you wait for an expert for? Who pays for the damage? While we always hope for the best, let’s walk through how to be prepared for the worst.

Step 1: Inspect for Immediate/Emergency Damage

Depending on the size of the tree or the force with which it hit your home, some damage may be immediately obvious. If the tree has penetrated your roof, windows or siding, it will be hard to miss. But in most cases, this doesn’t actually happen. A tree lands on your roof and the damage is typically only exterior and often is underneath the tree in a way that may not be visible without equipment or risky roof access. Immediately following the incident, do a basic safety check first. Look for downed power lines, gas leaks, structural sagging – all things that mean you should vacate the house and call emergency services.

If you don’t see signs of imminent danger, access your attic to check for any penetration or daylight coming through. This may be hard to do if the incident happens at night, so double check when it’s daylight. Next, look for water intrusion – even if there isn’t a visible hole. You may see seeping water coming through the roof deck from the inside where shingles have been lifted or come off.

Whatever you find, document everything! Take photos and videos from multiple angles where it’s safe to do so. This will matter enormously for any insurance claims that need to be made. Unless it is absolutely critical in order to exit the home or for immediate safety, avoid moving debris or cutting the tree yourself, especially if it’s resting up against the house. Shifting the weight of a tree can actually cause further structural damage, and one large limb or piece being moved off the house can drag across and remove shingles, gutters, siding, etc.

Most insurance companies will actually require you to take “reasonable steps” to prevent any further damage, but this does not mean getting on your roof or putting yourself in danger. Tarping your roof is a job for a professional. Your “reasonable steps” should be calling a tree removal company and roofing company as soon as possible.

Step 2: Reach Out to Insurance

As soon as you’ve documented the damage, reach out to your insurance company, even if you’re not sure yet that you’ll need to make a claim. You can ask them specifics about what they consider “reasonable steps” to mitigate any damage, but again – no one should be asking you to put yourself in danger. Instead, ask them if they have preferred vendors for doing this kind of temporary repair work.

Clarify with your agent or representative what exactly is covered in your policy. If your home is not actually damaged by the tree, the cost of removal may or may not be covered. Schedule an insurance adjuster to come inspect your property as soon as possible. Have your documentation ready to share – some insurance companies will have you email or upload photos to their app or website. In the meantime, keep every receipt for any work you have done for immediate repairs, tarping or even hotel costs if you’ve had to vacate your home.

Phase 3: Call in the Professionals

Your insurance company may have preferred contractors and vendors they work with for this type of job, but most policies do not require you to use those vendors. Whether the reference comes from them or elsewhere, you should call a licensed, insured tree removal company ASAP. Until the tree is removed it will be impossible to know the extent of the damage done to the house. As best as you can, coordinate the timing between the tree removal and a roofing inspection by a licensed roofing contractor as closely as possible.

Even if you don’t see signs of a leak, bring in a professional roof inspector. Hidden damage like cracked shingles, missing shingles or compromised flashing are very common and not always visible from the ground. Get a detailed, written estimate from the roofing contractor to supply your insurance adjuster. If possible, work with tree removal and roofing companies who are experienced with insurance claims and who have a process in place for how those jobs are estimated and billed.

Once the inspection is complete and repairs are scheduled, make sure the area stays properly secured until the fix is complete. Especially since storms tend to come in waves in our area, it’s important to try and avoid any additional damage that could complicate a claim or put any of the fault on you.

Step 4: Finalize the Claim

Hopefully the damage is covered by your insurance and the vendors you’ve worked with understand the claims process. In many cases, contractors will bill your insurance company directly. But in other cases, you’ll pay out of pocket, submit your receipts to your claims agent and then your insurance company will cut you a check for what is covered, minus your deductible. This can be stressful, as it’s not always clear that all expenses will be covered, but the best thing you can do is document everything fully, and submit everything you have in an organized, clear way.

Protecting Your Roof While Power Washing

This is the time of year that many Hampton Roads homeowners get outside and start tidying up their yard and home’s exterior as outdoor living season takes off.

For some, this includes power washing off mold, mildew and other dirt that has accumulated on vinyl siding, wood fascia, gutters and even brick. While this is a good task to stay on top of to keep your house looking good and to protect your home’s building materials from decay, there are also risks, especially the higher up you go.

It’s tempting to take the power washing all the way to the top – especially when you see algae and mold buildup on your roof. If it works on the siding and driveway, why not the roof, right? But the damage you can cause to yourself and your home with this well-intentioned chore could be disastrous.

What Happens When You Power Wash Shingles

It’s never a good idea to power wash your roof. First and foremost, it’s incredibly dangerous to you. Walking on a slick, steep slope roof with a powerful tool in hand is a recipe for injury. But it’s also likely to do more harm than good to your roof as well. Here’s how:

  • Granule loss: the protective granules embedded in asphalt shingles are what shield them from UV rays and weather. The high pressure of the pressure washer strips them away, which can make them age faster.
  • Shingle breakage and cracking: older or already-weathered shingles are brittle; the added pressure can crack, split, or blow them away entirely.
  • Voided manufacturer warranty: many shingle manufacturers explicitly exclude damage from pressure washing, so don’t take any chances of losing a valuable warranty.
  • Water penetration to roof decking: a power washer has the ability to raise shingles up when the spray is pointed at the right angle. When that happens, water can penetrate to the underlayment and even to the roof decking, leading to rot, mold and eventually structural damage.

Power Washing Fascia, Gutters and Soffits

It’s also tempting to power wash the fascia, gutters and soffit on the outside of your house, as they can tend to get mildewed, especially in highly shaded areas or on the north side of your home. There are some ways to do this safely but keep these points in mind.

  • Upward spray under shingles: angling the wand upward forces water past the shingle’s overlap. As mentioned above, this can penetrate to the roof deck, causing much bigger and long-term damage.
  • Shingle lifting and loosening: the force can break the seal strip between shingles, leaving them vulnerable to strong wind lift afterward.
  • Gutter loosening: the force of a power washer may loosen or even detach gutters from the fascia or your home, or downspouts from their connection points. When gutters are not in place, they don’t move water away from your home correctly, which can lead to water damage along your foundation.
  • Soffit penetration: water driven into soffits can reach attic insulation, causing moisture buildup and mold growth inside the home.

What Should You Do Instead?

You want your home to look beautiful and protect it from long-term staining and damage, but there are right ways and wrong ways to do that. Here are a few ideas that are safer but still effective.

  • Soft washing: consider a low-pressure application of a biocide or cleaning solution designed specifically for roofs. These often attach to regular water hoses and can kill algae and mildew without physical force.
  • Professional gutter cleaning: Hire a local professional to manually clean your gutters with professional tools and leave the ladder climbing to them.
  • Annual professional roof inspection: catch buildup and early damage before it becomes a bigger problem. Call your local roofing professional if you have any concerns about roof aging, damage or maintenance. They will know what to look for and also how to identify and deal with it safely.
  • Algae-resistant shingles: there are some roofing materials now that have built-in algae resistance. Talk to your roofing contractor about these options if you’re considering a roof replacement. This is a particularly good choice for homeowners in the Hampton Roads region, which sees wet, humid weather year-round.

Take the Pressure Off Yourself

Your roof is your home’s first line of defense against the elements. Don’t let a DIY weekend compromise it, costing you money or even your safety. At Andrews Roofing we know all the telltale signs of roof damage – whether it was caused by you, the weather, age or previous owners. Contact us today if you have any concerns about your roof’s condition; we’d be happy to help point you in the right direction, while taking the pressure off you.

The Role of Proper Ventilation for Roof Health and Energy Efficiency

When Southeast Virginia summers hit, your roof starts working overtime. But if it’s not breathing right, you could be facing major issues.

Hampton Roads homeowners know summer doesn’t ease in gently. By late May (or even April!), temperatures are climbing into the 90s, humidity is thick, and on a clear, sunny day, your attic temperature can soar past 150°F. Most people only think about their roof when something goes wrong that’s immediately visible – a missing shingle after a storm or stain on the ceiling after a heavy rain, but one of the most damaging things that can happen to a roof in this region is largely invisible until it’s too late: poor ventilation.

Proper roof ventilation isn’t a luxury or an up sell – it’s a foundational part of a healthy roofing system. When ventilation fails, the rest of your home’s structure will feel it, as will your energy bills. Here’s what Southeast Virginia homeowners need to know heading into another hot, humid summer season.

How Proper Roof Ventilation Works

A properly ventilated roof system is simple in principle: fresh air enters through intake vents (typically at the soffits) and hot, moist air exits through exhaust vents (at or near the ridge). This continuous airflow keeps your attic from becoming a heat and moisture trap.

Without adequate ventilation, two major issues will arise:

  • Extreme heat builds up in the attic space during the day, radiating downward into living areas and stressing roofing materials from below.
  • Moisture will occur from condensation, when the warm, humid air from outside meets cooler surfaces inside and is trapped.

Condensation: The Silent Destroyer

In the Tidewater region, condensation is a serious concern. Our region’s climate means we deal with heat and humidity in the summer months and temperature swings in the fall and spring, both of which create prime conditions for moisture to accumulate in an attic.

When warm, humid air gets trapped in a poorly ventilated attic, it condenses on the cooler surfaces of your roof’s structural components, from there the damage can compound quickly.

Your roof decking (typically the sheets of plywood you can see from inside your attic) will be the first material to be affected. Over time, moisture exposure will cause the wood to swell, warp, and eventually rot. Once this happens, it can no longer hold fasteners properly, meaning your shingles aren’t as secure as they should be.

From there, moisture can work its way into the rafters, which bear the weight of your whole roof. As you can imagine, wood rot in rafters is serious and in advanced cases, it leads to a sagging roofline and significant structural repairs.

Finally, your insulation will incur damage. Wet insulation loses its ability to resist heat transfer, packs down and clumps, and becomes a breeding ground for mold. Once it’s moisture-damaged, it typically has to be replaced entirely. And mold itself isn’t just a structural problem; it’s a health concern that requires expensive remediation. The good news is that all of this is preventable with proper ventilation.

The Cost of a Poorly Ventilated Attic

We’ve all been hearing about the rise in energy bills, but there’s one reason for this that may not be top of mind: roofing ventilation.

When your attic reaches 140–160°F on a hot afternoon, which it easily can without proper airflow, that heat radiates directly through your ceiling into your living space. Your air conditioning system then has to work significantly harder to maintain a comfortable temperature. It cycles more frequently, runs longer, and wears out faster.

A properly ventilated attic stays dramatically cooler. Adequate attic ventilation can reduce attic temperatures by 40°F or more on peak summer days. That’s a huge reduction in the work your HVAC system is doing, as well as your monthly bill.

Ventilation is Just One Part of the Puzzle

Ventilation is just one part of a healthy roof system. Shingles, underlayment, decking, insulation, and ventilation – every layer depends on the others to perform as designed. Shingles can be in perfect shape while the decking beneath them quietly rots from trapped moisture. Insulation loses its effectiveness the moment it gets wet. A well-designed ventilation system is what keeps everything else working.

That’s why when we evaluate a roof, we look at the complete picture, not just the outermost layer. A comprehensive inspection includes checking soffit vents for blockages, evaluating ridge vent access, and looking for signs of moisture damage in the decking and framing.

Signs Your Roof May Have a Ventilation Problem

If you’re not sure whether your roof has ventilation issues, here are some warning signs to watch for as we head into the hot months:

  • Your upstairs rooms are noticeably hotter than the rest of the house, even with the AC running
  • Your energy bills spike sharply in summer months
  • You notice a musty smell in your attic or upper floor
  • There are visible staining or dark spots on attic sheathing
  • Your roof shows premature aging such as curling, cupping, or granule loss on shingles that aren’t that old
  • Ice dams formed along your eaves last winter (a telltale sign of uneven attic temperatures caused by poor ventilation)

Don’t Wait Until Summer to Find Out

The best time to address ventilation issues is before the heat arrives. By the time your attic is baking in July and your energy bills are quite literally through the roof, the damage may already have started.

Andrews Roofing serves homeowners across Hampton Roads – from Virginia Beach and Chesapeake to Suffolk, Portsmouth, Norfolk and the surrounding communities. We understand the specific demands our climate places on roofing systems, and we know that a truly healthy roof is one that’s been built and maintained as a complete system.

If it’s been a while since your roof has had a thorough inspection or if you’ve noticed any of the warning signs above, contact us today. We’ll evaluate your roof from shingles to soffit vents and give you a clear, honest picture of where you stand and what will continue to keep your home healthy heading into summer.
