Don’t Let Christmas Ruin Your Roof

The holidays are here and for many folks that means decorating their homes – inside and out. So many of the classic Christmas movies we all love to watch every year involve some sort of rooftop antics. Whether it’s Santa’s sleigh scraping across a gabled dormer or Clark Griswold stapling strand after strand of lights directly to his shingles, these scenes that fill most people with holiday cheer make roofing professionals cringe! That’s because Christmas and holiday decor can cause real, serious damage to your home’s exterior, and particularly your roof. We don’t mean to be a grinch, but while we love to get in the holiday spirit as much as anyone else, we have a few recommendations to help make sure that Christmas doesn’t ruin your roof (and your holiday cheer) this year.

Inspect Before You Decorate
Before putting any type of decorations directly onto your home’s exterior surfaces, give them a once over. Are any shingles peeling or missing? Are gutters loose anywhere? Are there gaps or holes in siding? Is there debris in any roofing valleys? All of these issues should be dealt with regardless of whether or not you’re decorating, but they can become especially problematic once you add things to them. Debris can blow around and destroy your decorations – especially anything inflatable. Loose shingles can be pulled off if weight is placed directly on them. Loose gutters could even fall off or become more damaged if strung with lights. If your inspection turns up any issues, call in a licensed roofing contractor to fix the issue before decking the halls.

Use Proper Lighting
It’s not uncommon to collect Christmas decor and use the same things for decades on end. But when it comes to exterior lighting, it’s best not to get nostalgic about anything. Outdated or worn string lights and electric decor can cause major damage to your home including fire damage. Additionally, any lighting that isn’t rated for outdoor use can become a liability. Make sure anything that you plug in is UL rated, which is typically listed on the product’s packaging or online description. The UL seal means that a product has been tested by the UL nationally recognized safety and sustainability standards and has been found to be free from a reasonably foreseeable risk of fire and electric shock.

Watch Your Weight
No, not your waistline, although we could probably all stand to keep an eye on that this time of year. We’re talking about weight you place on your roof which isn’t designed to withstand downward pressure and weight over long periods of time. Attaching heavy decorations to the top of your house can cause structural damage to your roof decking and eaves. You can check with a structural engineer or contractor to find out what your roof’s long-term weight bearing capacity is, but you can also use common sense – don’t plop a three-hundred-pound Santa and his sleigh up there and not expect for some issues to occur. Conversely, if you place lightweight decor on your roof, ensure that it is properly secured so it doesn’t come loose and cause damage to other areas of you or your neighbors’ homes.

Most Importantly: Use Proper Fasteners!
We cannot stress enough how much damage can be caused by stapling, nailing or screwing lights and decorations to your home’s roof. Shingles are not self-sealing. Any hole and penetration you put in them will only get bigger and cause more damage over time. If you must have lights along your roofline, there are great products out there that create a professional and clean design without penetrating any exterior materials. Gutter clips and shingle clips (or all-in-on-products) are great alternatives. They are easy to use and well worth the minimal investment, especially considering the cost of the damage nails and screws will eventually cause to your home.

We hope all of our neighbors in the Hampton Roads region are celebrating the season with good spirits and lots of safety. All of us at Andrews Roofing want to wish you a wonderful holiday season, a Merry Christmas and a Happy New Year!

Does Your New Roof Have a Warranty?

When you invest your hard-earned money into your home, especially a sizable investment for something like a new roof, you want to know that you’re protected.

It’s important to understand, when pricing out a new roof and receiving quotes from roofing contractors, what the elements of a roof warranty include. There are a few different things to consider and questions to ask of anyone you’re considering hiring.

Roofing Material Warranties

Most roofing materials come with their own manufacturer warranty. For asphalt shingles, it’s common for manufacturers to provide a 25–30-year warranty, although some do offer longer or “lifetime” warranties. Many metal roofing materials are covered for up to 50 years or longer. The important thing to remember here is that their warranty only covers the material, not labor and not the cost of disposal. Some companies offer enhanced coverage you can purchase that will pay for a full replacement including workmanship for a certain period of time, but those warranties can be costly and require additional certifications and documentation by the contractor.

When receiving quotes on a new roof, ask questions about the materials and manufacturers each contractor uses, and what the warranties look like for each. A good roofing company will know their chosen manufacturer warranties inside and out and have insights about what will be best for your situation, home and location. Manufacturers will only honor warranties on their materials if they have been installed correctly and by a licensed contractor, so make sure you go with a reputable company.

Roofing Contractor Warranties

The other side of roofing warranties is the coverage that your roofing contractor provides to cover their own workmanship. These can vary widely from company to company. Because of that, it’s a good idea to get all of your quotes in writing along with a printed copy of their warranty coverage details. A workmanship warranty will typically cover damage that is caused by improper installation. Make sure the company also covers any materials that may be needed to fix the damage incurred.

At Andrews Roofing we provide a 10-year workmanship warranty on all of our shingle installs, provided we are the primary contractor to the client. This is longer than the industry norm for workmanship warranties. In addition to covering our work on new roof installations, we also warranty any repair work we do on a roof that we installed. We’ve been working in the Hampton Roads region for years, and our reputation in the community illustrates how we stand behind our work. Make sure that whoever you end up hiring has a good standing and reputation in your own community. Check online reviews and ask around with your neighbors. You can even contact the Better Business Bureau or licensing board of your state to make sure the company is in good standing.

Protecting Your Roof Warranty

It’s critical that you understand the requirements of your warranty to avoid rejected claims. If a leak or other damage is incurred, it should be promptly reported to the warranty department so corrective measures can be made as soon as possible. If you do have damage or issues, go back to your original roofing company. Unless they have proven themselves to be completely untrustworthy, it’s best to have continuity in the warranties and work. And finally, do not forget to register your warranty with the manufacturer after the work is completed if it is required. Some warranties do not require formal registration and some do, so it’s important to review your warranty package carefully when you receive it. For enhanced and upgraded warranties, the contractor may have to submit paperwork on your behalf with additional documentation.

We Stand Behind Our Work

We stand behind the work and the materials we use at Andrews Roofing. We’ve been in the business long enough to know which manufacturers do the same, and that’s who we use and recommend to our clients. Our exceptional workmanship warranty and reputation in the Tidewater Region can help you have confidence in your home investment for many years to come.

Why Good Flashing Is Critical for Your Roof

When we talk about roofing repairs and replacements, people typically just think about shingles or other types of exterior roofing materials like metal, cedar shake or clay tile.

But there are many critical pieces that go into a good, solid roofing system, and one of them is flashing. Flashing is more important than people think, and improperly installed, damaged or missing flashing is one of the most common causes of roof leaks.

What is flashing?
When a roof plane meets a vertical surface, shingles and other roofing materials can’t be used to protect those parts of the roof. Instead, flashing is installed around vertical roof features to direct water away from these critical areas. Roof flashing is a thin metal material that comes in large sheets and is cut, molded and layered to fit where it is needed. It may also be made out of a plastic membrane for some applications or you may see PVC used at penetrations as pipe collars, sleeves and other fittings that function as flashing.

How does flashing work?
Without flashing, water could penetrate between the crevice of say, a shingle and a chimney. Flashing ensures that the water runs back over the roofing material, down the roof plane and off the house, hopefully into a clear and clean gutter. Other areas where flashing may be used includes vents, skylights, dormers, and sometimes even between the edge of the roofline and a gutter system.

What is flashing made of?
The materials used for flashing has changed over the years, from lead-coated materials to safer and more durable types of metals. This includes aluminum, copper and galvanized steel. Depending on the building codes where you live, a roofing contractor may have to use a specific material. While we typically use aluminum flashing on residential installs, the material itself is dependent on the specific roof and situation.

When should I replace or repair flashing?
If your home is experiencing a leak, and it does not appear to be from missing shingles, punctures or other damage, it may be time to check the flashing. Check the areas we discussed above to see if any of these issues have occurred:

  • Holes, dents or bending
  • Corrosion or rusting
  • Missing nails or loose nails
  • Loose or missing flashing

If you spot any of these issues, it’s time to call in a qualified roofing professional. Replacing flashing yourself is dangerous and if done incorrectly, can cause even more damage to your roof and ultimately the interior of your home.

When having your roof replaced, it’s a good idea to have the flashing replaced at the same time. Some areas may be able to be reused, but to ensure a watertight seal and a lifespan equivalent to your new roof material, full replacement is likely worth the minimal extra investment. Your existing roof flashing materials may also not be up to current code, in which case a roofing contractor will be obligated to replace it. Alternatively, it’s very possible that when you are experiencing a leak caused by flashing that only the flashing will need to be replaced, and that a full roof replacement is not necessary.

If you are having issues with your roof’s flashing, or have a leak you haven’t been able to identify the cause of, give Andrews Roofing a Call. We are experienced in the specific issues Hampton Roads homeowners encounter, especially during storm season. Contact us today.

Metal or Shingle Roof: What’s Right for Your Home?

Metal roofs have become increasingly popular in residential structures in recent years, whereas asphalt shingles have been the de facto material of choice for decades. There are plenty of good reasons to consider metal roofing, but is it right for your own home?

Here are a few things to consider before replacing your roof with metal.

Durability and Lifespan

Metal roofs have a lifespan of 50 or more years – twice the length of a traditional asphalt roof. In addition to lasting much longer, they are also more durable. If installed properly by a licensed roofing contractor, some metal roofs can sustain up to 140 mile per hour winds. This is a serious benefit in a hurricane and storm-prone area like Hampton Roads. For homes in areas prone to wildfires, metal roof systems are less likely to ignite or catch fire from a spark or rouge flame.

Sustainability

When replacing your roofing system, there are some things to consider about the environmental friendliness of your choices. One is the material itself. In the case of metal roofs, the material is usually 25-95% recycled content, and metal roofs are themselves 100% recyclable. There’s also the energy efficiency of your roof. Metal roofs reflect UV rays, which can reduce the temperature of the surface and can result in a 10-25% reduction in cooling costs for your home, saving energy and fossil fuels.

Affordability

While there are great benefits to metal roofs, and while their popularity has increased, they are still significantly more expensive than traditional asphalt shingles. Depending on the exact type of metal materials used, it may cost two to three times more than an architectural shingle replacement. Metal roofs can save you money over time for the reasons mentioned above, but you should consider how long you plan to live in your home and whether you will be there long enough to get a return on your investment.

Sound

While modern building methods do offer metal roofs a bit more insulation from sound than in the old days, they are still louder than a traditional roof. Some people love the sound of rain on a metal roof, while others may find it bothersome over time. There is nothing definitively good or bad about this aspect of metal roofs, but it is something to keep in mind when making the decision.

 Snow

For areas where snow is common or in commercial situations, metal roofs will typically need snow guards. These little metal semi-circles or horizontal strips of metal keep snow from falling off in large clumps onto someone or something below. Even if you’re not in a snow prone area, you will need snow guards on steeply pitched roofs such as front porches and porticos. A qualified roofing contractor who is experienced with this material and installation will know the best way and the best places to install snow guards on your metal roof.

 Style

Manufacturers of metal roof systems have made major advances in the style and color range of metal roofing. In some cases, metal roofs can even look like traditional shingles from a distance. For the most part, though, metal roofs have a distinctive look and style which may or may not compliment your home. Some manufacturers have tools on their websites where you can visualize what different roof materials and colors would look like on a home similar to yours. Or you may just want to take some time to search the internet for photos of homes with different types of metal roofs.

An experienced roofing contractor can also assist you in visualizing and choosing the appropriate material. At Andrews Roofing, we’ve completed many homes with metal roofing, and one of the approaches that has become popular with our clients is to mix roofing materials. The primary roof of the home may be architectural asphalt shingles, with small overhangs, porches or dormers using a complimentary metal material. This look works great on Craftsman style homes and more modern designs. It also gives the home the unique and high-end look of metal without as much of a cost increase.

If you are considering replacing your roof with a new metal roof, or if you just have questions about what roofing material is right for your reroofing project, contact Andrews Roofing. We’ve worked with clients in the Tidewater region for decades, and know the best materials, approach and application for all types of roofing systems.

How to Know When Your Roof Needs a Checkup

They say an ounce of prevention is worth a pound of care, but that doesn’t just apply to your physical health. The same could be said for anything you maintain, including your house and its major systems such as your roof. While there’s no getting around the fact that a roof will eventually need to be replaced, there are many things that can happen over the course of a roof’s lifespan that should be serviced, repaired and maintained. This is especially true in areas prone to severe weather such as the Hampton Roads region.

But how do you know when you should call in a professional roofing contractor? Here are a few things to keep an eye out for to help extend the lifespan of your roof.

Curling, cracking or buckling shingles are a tell-tale sign that your roof needs some attention. You may also notice asphalt granules in your gutters, which have deteriorated from damaged shingles. This doesn’t mean you need an entirely new roofing system! While this type of roof symptom can sometimes be a sign that a roof has reached the end of its serviceable life, it can also be an isolated incident that simply needs to be repaired or patched.

While it may not necessitate a total replacement, shingles that are damaged or worn should be a high priority on your home to-do list. Just a few curling shingles can allow water to penetrate your roof causing leaks, mildew and other interior damage.

Speaking of interior damage, dark spots on your ceiling or walls also signal that it’s time to have a roofing professional come out and inspect. Even if you don’t see a hole or missing or damaged shingles from the outside, the leak may still be the result of a failure in your roofing system such as loose or missing flashing, backed up gutters or damage that simply isn’t visible from the ground.

Dark spots indicate that moisture has penetrated your roof, the sheathing, decking, and potentially attic flooring. These are serious signs that should be attended to as soon as possible by a professional to ensure additional damage does not occur and that harmful mold and mildew do not start to grow.

Moisture in your attic may also be a sign of problems with your roof as well as your insulation. If you find that the insulation, wood, flooring, ductwork or other items in your attic seem damp, it may be caused by a lack of proper ventilation and/or unsatisfactory insulation. But these issues, over time, can also affect the health of your roof by causing water damage to decking from the underside. An ideal attic temperature is close to that of the temperature outside. This prevents condensation, which is often the cause of interior moisture damage. A licensed professional contractor will need to address these issues if you find them.

Of course, sometimes all of these things indicate that a roof has simply reached the end of its lifespan and needs to be replaced. Most modern asphalt shingle roofs have a lifespan of 20-30 years. In the cities of Virginia Beach and Chesapeake and across the Tidewater region, many homes and large neighborhoods were constructed in the 1990’s, making them the age now to need total replacement.

A qualified roofing company can provide you with a roofing checkup to help you determine whether a repair or total roof replacement makes the most sense for your home and budget. At Andrews Roofing, we provide professional evaluations, customized quotes and affordable financing options as well. Whether you think your roof needs an ounce of prevention or a pound of care, we can help. Contact Andrews Roofing today.

Roofing 101: Steep Slope vs. Low Slope

All roofs can be divided into two categories: steep and low slope. Low slope roofs have become increasingly popular on residential structures thanks to their clean, modern design and their ability to accommodate patios, gardens and more.

It’s important to understand the difference between the two when determining what type of structure to install, replace or repair or when choosing appropriate roofing materials.

Steep Slope
Steep slope roofs are technically any roof with a slope of 25% or more. They consist of five basic components:

  1. Roof covering – this could be shingles, tile, slate, cedar shake, or metal, as well as the underlayment that sits beneath them to protect the sheathing from weather.
  2. Sheathing – this is the board or sheet materials that are directly attached to the roof rafters that make up the roofline. This material must be covered by an underlayment material and roofing material (above) in order to remain structurally sound.
  3. Roof structure refers to the rafters and trusses that are structurally supporting the roof sheathing. This is the framing of the roofline which is a part of the skeleton of the house.
  4. Flashing is usually sheet metal that is installed at any point on a roof where there are joints, valleys, vents or chimneys. They function to prevent water seepage at these vulnerable spots.
  5. Drainage is a critical component of the overall roof design. It ensures that water is shed from the roof in a way that doesn’t compromise the structure at any point. Drainage has to be considered when designing the layout, shape and slope of any roof structure.

Low Slope
For all intents and purposes, a “low slope” roof is usually flat, but technically it refers to any roof that is between 0% and 24% sloped. They also consist of the same five basic elements, but the details differ somewhat.

  1. Roof covering for low slope roofs often consist of a single-ply membrane such as TPO, E.P.D.M., Modified Bitumen, or PVC. It is also common to see what are called “built up systems” which are composed of multiple layers of sheet materials and asphalt, often covered with a gravel coating. Other material options include spray foam or metal. All materials require an underlayment between them and the roof sheathing.
  2. Sheathing for low slope roofs can differ quite a bit from steep slopes. There are some structures with basic wood boards like a residential structure, but you may also see metal, concrete, gypsum, tectum and other fibrous materials.
  3. Roof structures of a low slope roof are conceptually the same – rafters, trusses and joists that support the sheathing, but the materials here may differ as well and could be steel, wood, or concrete.
  4. Flashing does not differ much from a steep slope installation and serves the same purpose to prevent water seepage at vulnerable spots.
  5. Drainage for a low slope roof is critical since the basic design of it does not shed water the way a steep slope roof does. For low slope roofs with any sort of incline, gutters, internal drains and downspouts can be effective. For truly flat roofs, special design considerations need to be made, and options like stepped slope insulation may be a safer bet.

Either roof can have its challenges. Obviously steeper slopes are more difficult to access and for shingled steep roofs, they will have a harder time fighting gravity over time. Mansard shingled roofs, for example, sometimes have nails tear through the shingles as they age. On the other hand lower slopes that are “walkable” and shingled, but still have a slope that falls within the shingle manufacturer’s specifications for shingle installation, can present greater challenges with wind-driven rain getting under the shingles, debris accumulation, needing additional barriers for protection such as ice & water shield, etc.

Any solid roofing solution – whether it’s for a home or commercial building – should balance all five of these components. At Andrews Roofing, we address each of these components equally when consulting with clients and assessing roofing needs. While the roof covering may have the most visual impact, we understand that everything below that is just as critical. If you have questions about what type of roof is ideal for your structure, or if you need a steep or low slope roof repaired or replaced, contact Andrews Roofing. We have decades of experience in both commercial roofing and residential roofing construction in Hampton Roads and we’d be happy to come out and give you an estimate and professional recommendation.
