Shopping for a new house? Don’t forget to look up!

When potential home buyers are house shopping, they tend to focus on a home’s interior features, its location, neighborhood, and general curb appeal.

But one thing you should never overlook in a listing is a home’s roof. As an essential structural component of any home, a roof is one of the largest investments owners can make. In today’s cut-throat, competitive housing market, buyers are often willing to waive home inspections to have their offer considered over others. But this is never a good idea – buying a home without knowing about the condition of its roof is a risk that could cost you tens of thousands of dollars.

So, what should you look for as you leaf through those listings? Here are just a few considerations for prospective homebuyers when evaluating a property’s roof.

  1. Age: The age of a roof can tell you a lot and is perhaps the most important fact to know about it in advance. An older roof may be nearing the end of its lifespan and could require costly repairs or replacement soon. Look for signs of wear and tear such as missing or damaged shingles, sagging areas, or water stains on the ceiling. If the listing doesn’t say the roof’s age, have your real estate agent inquire about it.
  2. Material: Different roofing materials have varying lifespans, maintenance requirements, and durability. Most commonly in the Hampton Roads region you’ll see architectural asphalt shingles. But there are also metal roofs, clay tile, wood shake, and even synthetic recycled materials. Consider our local climate and what makes the most sense for your lifestyle and the home’s location when assessing roofing materials and whether you’re ready to take on their care.
  3. Leaks and Water Damage: Water damage can lead to extensive structural issues and mold growth. During a home inspection, carefully examine the interior ceilings, walls, and attic for any signs of water stains, mold, or mildew. Additionally, look for evidence of leaks around skylights, chimneys, vents, and flashings. All of these things can point to a roof that at best needs repairs and at worst needs to be completely replaced.
  4. Gutters and Drainage: Proper slope and drainage is essential for preventing water from pooling on a roof and causing damage – this is especially important in low slope or flat roofs. Likewise, gutters keep water from running off the roof and toward the foundation of a house, causing water damage that can affect a home’s overall structure. Inspect the gutters and downspouts for debris buildup, corrosion, or damage. Ensure that they are securely attached and effectively channel water away from the foundation of the house.
  5. Ventilation: Adequate attic ventilation helps regulate temperature and moisture levels, prolonging the lifespan of the roof and preventing issues like ice dams and mold growth. Check for vents along the eaves, ridge, and soffits, and ensure they are clear of obstructions. Improper ventilation can not only reduce the lifespan of a roof, but also dramatically increase your utility bills.
  6. Previous Repairs or Replacements: Inquire about any past roof repairs or replacements and obtain documentation if available. A well-maintained roof with a history of regular inspections and maintenance is sure to be in better condition than one that hasn’t. A roof that was recently replaced likely has material or workmanship warranties. Having the information about that is critical in case you need to make a future claim.
  7. Professional Inspection: While an initial visual assessment of the roof is something you can do yourself while touring a home, hiring a qualified roofing contractor or home inspector for a thorough evaluation is highly recommended. They can identify hidden issues, assess the overall condition of the roof, and provide insights into potential maintenance or repair costs. Don’t skip this step!

Three Key Things to Consider when Finishing Off an Attic

Finishing off an attic is a popular way to squeeze more livable square footage out of an existing home. There are challenges to this type of renovation, however, and a lot of systems within the house should be considered, not the least of which is your roof. Since attics abut your roofing system, it is the most susceptible to poorly designed or constructed finished attics, so always make sure to use an experienced, licensed contractor. While we recommend having a professional do all the associated work for this type of project, here are a few things to consider ahead of time or to make sure your contractor addresses.

Ventilation
The number one most important thing to ensure during a finished attic project is maintaining proper ventilation. When an attic is unfinished, the system has space to breathe, while well-installed insulation and vents keep temperatures optimal to avoid condensation. But when drywall is put up, insulation is moved around and vents are covered, this can affect how the roof reacts to temperature changes. If not done correctly, this can cause condensation to build up between the roof and drywall, causing rot and mold to both surfaces.

If insulation is being reinstalled between the rafters behind the drywall, it’s important that air space is left between the insulation and the roof sheathing. There are special foam baffles that are made specifically for this purpose that should be used. There should also be a plenum (or connected air space) built into the design. You may notice that most finished attic rooms have a flat portion of the ceiling at the top (as opposed to an A-frame ceiling). That area above the flat ceiling is the plenum – it allows air from between rafters to move laterally as necessary in order to reach the roof vents.

If these design details are not incorporated into your project, rot will occur on your roof sheathing, drywall or both. The problem is that once an attic is finished off, it’s very hard to know these issues are happening until it’s too late and rot, mold and mildew have appeared. So be aware and discuss these details with your contractor ahead of time.

HVAC
For many homes, much of the HVAC system’s ductwork lives in their unfinished attic. Whether mounted to the rafters or lying across the floor of the attic (or both), all of it will need to be repositioned and worked around. This may require some creative designing to allow space for ductwork to go above and behind the drywall with enough space for insulation and air flow. This means you may need to call in an HVAC company in addition to your general contractor.

If your new finished space is going to tap into your central air system, then the ductwork will need to be reconfigured by an HVAC specialist. It would be wise to work in access panels for key parts of the HVAC unit so repairs can be done without having to rip out drywall. If you don’t plan on tapping into the main system, consider something like a mini split AC unit that is efficient, can be used when needed, and can help with maintaining reasonable temperatures in the space to help decrease any chance of condensation.

Plumbing
Although less likely, there is a chance that some key plumbing elements are housed in your attic that will also need to be worked around or reconfigured by a licensed plumber. The most common issue arises with homes that have hot water heaters in the attic. Space will need to be carved out for housing it, typically in a small closet so there is still easy access for repairs and replacement.

If you do decide to finish your attic space, discuss all of these concerns with your contractor, and also keep a close eye on your finished room after it’s complete. Check for mold or mildew on drywall and address it as soon as you see it. Make sure the room stays a reasonable temperature and investigate any damp or dank smells that may occur. If you have any concerns that a finished attic space may have caused damage to your roof, please contact Andrews Roofing immediately and we will send an experienced, licensed and insured professional to your home for an inspection and estimate before the issue gets worse.

How to Protect Your Roofing Investment

A new roof may be one of the largest investments you make in your home.

So, once you’ve made that upgrade, it’s important to protect it. Most people don’t spend much time thinking about their roof – until something goes wrong. But some forethought and a little regular maintenance can extend its life and the value you get out of it. Here are a few tips on how to extend the life of this important home investment.

Keep those gutters clean

One of the most critical things you can do to help your roof remain healthy and stable is to keep your gutters clean and clear of debris. When gutters are clogged, water can push up under the shingles, causing rot and damage to the sheathing below. Clogged gutters can also cause excess water to fall off the edge of the gutter and right toward your home’s foundation. Over time, this can cause foundation cracks, moisture damage, termites, basement flooding and more.

While it’s critical to keep your gutters clean, it’s also important to stay safe. If you plan to clean your own gutters, always do so with another person who can stabilize the ladder while you clean. Otherwise, find a locally owned and operated company who provides professional gutter cleaning services and get on their schedule for regular seasonal or semi-annual maintenance.

Do a regular visual inspection

A simple visual inspection once a month, or right after large storms, can help identify potential trouble spots. Things to look for include cracked or curled shingles, missing flashing, loose shingles or flashing, or mold or mildew build up on shingles. Inside your home you can do regular visual inspections in your attic or crawl space. Check for damp areas, excessive drafts, and of course – obvious holes or water damage.

If you see any of these issues, give your roofing contractor a call. There may be warranties on your roofing materials that could help solve the issue. If there has been true damage to your roof or interior, it may also be time to call your insurance agent.

Keep your roof clean

In addition to being unsightly, areas of mold, mildew and algae on your roof can actually lead to more serious damage. Mildew can cause shingles to warp over time, losing their stability and protective purpose. It can also be indicative of worse water damage to your roof’s sheathing. We do not recommend cleaning your roof yourself, as this can be a dangerous activity. Find a qualified, professional cleaning service who can do this for you on an as-needed basis.

Trim your trees

One of the best ways to prevent damage to your roof is to keep the trees and landscaping around your roof trimmed and maintained. Trees with overhanging branches should be cut back by a professional tree service as should any nearby dead or dying trees. After any major storms, check the trees on your property to make sure no branches have broken and gotten caught up on lower limbs – these can become damaging flying debris in the next storm.

Keep an eye on your attic

Your attic is the foundation of a healthy roof. It provides two critical elements for a long roof life: ventilation and insulation. Proper ventilation in your roof, along with appropriate insulation, eliminates moisture build up that can combine to cause rafters and sheathing to rot, shingles to buckle, and insulation to lose its effectiveness. A licensed contractor can help if you think either of these two things may be lacking in your attic.

Call a professional roofing company

If your self-inspections reveal any of the issues mentioned above, it’s important to call a local, licensed roofing company. Roof repairs are too serious and potentially dangerous to be DIY. Protect the rest of your home by maintaining a healthy roof alongside a trusted roofing company.

If you’ve noticed any issues with your roof, or would like to have your roof inspected for damage and deterioration, contact Andrews Roofing today. We’d be happy to come out to your home and help determine what your next best steps are – whether that’s a roof repair or replacement.

Why Roof Ventilation Is So Important

As the weather changes from cold to mild to hot in Hampton Roads, you may find yourself fiddling with the thermostat more than usual. The dramatic changes in temperature that the spring season brings to southeast Virginia can affect a lot of systems around your house, and your roof is no exception.

Your roof is highly susceptible to temperature changes both inside and outside of your home due to the sheer surface area and exposure to the elements. This is why proper ventilation is critical. In fact, ventilation may be the most important factor in roof durability. It’s easy to focus on the durability factors of your roofing materials – the lifespan of metal versus asphalt shingles versus composite materials and so on. But no matter how well made a roofing material is, if it’s installed over an unventilated roof, it’s bound to fail.

When the temperature swings from cold to hot and back again, especially with the level of humidity that’s standard for the Tidewater region, condensation can form in your attic, causing rafters to rot, shingles to buckle and insulation to deteriorate and lose its efficacy. While the code requirements for attic ventilation can vary greatly from state to state, a general ventilation formula is based on the length and width of the attic space beneath it. There should always be a minimum of one square foot of free vent area for each 150 square feet of attic floor. Vents should be placed proportionately at the eaves and at or near the ridge.

Because of their importance to your roof’s overall health, it’s important to never block off sources of roof ventilation such as louvers, ridge vents or soffit vents – even in the winter! You may think you want to keep the cold winter air out of your attic, but maintaining an even temperature between the surface of the roof and the space beneath it is actually helpful in preventing moisture build up and damage.

In addition to this free flow of air, insulation can play a key role in proper attic ventilation. Ideally an attic will have a gap-free layer of insulation on the attic floor to protect the house below from heat gain or loss. It will also have a vapor retarder under the insulation and next to the ceiling to stop moisture from rising up from the home into the attic space. Then there should be enough vented spaces to let air in and out, and finally, there should be a minimum of one inch between the insulation and the roof sheathing. With these systems in place, your attic and roof are likely to stand the test of time.

The best way to ensure that all of the proper ventilation measures have been taken to extend the life of your roof is to work with a qualified, licensed roofing contractor. At Andrews Roofing, we’ve been providing Hampton Roads homeowners with high quality roofing services for years, and we are experienced with the unique seasonal and meteorological issues that homes in this area face.
