Hardie Plank fiber cement siding is currently the top choice for Virginia homeowners thanks to its durability and style. Vinyl siding is also a close second due to its affordability and ease of maintenance.

Siding plays a big role in your home's energy performance. When installed with proper insulation, it significantly reduces air infiltration and helps maintain indoor temperatures. Without insulation, you risk increased energy loss through drafts and leaks.

Windows, siding, and attic insulation (including air sealing) are the three biggest factors. If any of these are outdated or poorly insulated, your home may be losing a substantial amount of energy—and money.

Common red flags include discoloration, warping or waves, sagging or hanging panels, and missing pieces. If your siding looks tired or worn, it might be time for a replacement.

Yes, we do our best to match existing siding. However, if your current siding is more than five years old, color matching may be difficult due to fading and discontinued styles. When possible, we’ll find the closest match available.

Yes! All our siding installations come with strong warranties, so you can feel confident in your investment.

Yes, we offer environmentally friendly siding solutions like insulated siding systems with drop-back insulation. These help reduce energy usage and improve your home’s sustainability.

Absolutely. We offer custom window solutions tailored to fit unique shapes, sizes, and architectural styles, ensuring both a perfect fit and a seamless look for your home.

Most windows should be replaced every 15 to 20 years, depending on material quality and exposure to the elements. If your windows are drafty, hard to open, or showing signs of deterioration, it may be time to upgrade.

Double-pane windows provide better insulation, reduce outside noise, and help lower your energy costs. They also reduce condensation and improve indoor comfort all year long.

Signs that your windows may need attention include drafts, condensation between panes, difficulty opening or closing, and visible damage or rot. We can assess whether a repair or full replacement is more appropriate.

While a lot of people think that a leaking roof needs to be replaced, this may not be the case unless the roof is old. Missing, cracked, broken, and curling shingles can be repaired and replaced to stop a leak, while older roofs or roofs with multiple leaks or widespread issues should be replaced.

Costs vary greatly depending on the pitch of your roof, the type of shingles you have, what condition the roof is in, and how many layers of shingles you have. The best way to find out the cost is to have a free quote done.

While some small jobs can be tackled by DIY homeowners, major work or a roof replacement is a pretty complex process that requires training and thus should be left to the professionals. Professional roofing contractors goes to through training and certification by the manufacturer of the materials in order to obtain extended manufacturer warranty. The manufacturer won’t offer (or void) the warranty if the roof is repaired by a person he is not trained by the manufacturer.

There are a lot of factors that go into how long a roof will last. While most roofs have a warranty, this doesn’t mean that your roof will necessarily go this long without needing to be replaced. Some will wear out faster due to severe weather and environmental conditions, while others could last longer. Most roofs, however, are designed to last between 15 and 25 years; some types of slate and metal roofs could last longer.

Severe weather, direct sun, algae and mildew growth can all be factors in what causes a roof to wear out. Hail stones striking the roof and removing some of the granules are also a problem. Darker colored roofs tend to wear out slightly faster than lighter colored roofs as well.

There are a lot of factors that go into whether or not the hail is damaging to a roof. The age and condition of the roof can greatly impact how large a hail pellet needs to be. In general, however, pea and marble sized hailstones do not typically cause damage to a roof without high winds also being involved.

No, hail storms can vary tremendously even in a small area. The roofs can all vary in terms of age and condition as well, which will impact how they are affected.

Leaks can be tough to spot because water wants to find the path of least resistance and can travel for a while before finally showing up through your ceiling. You can try going into your attic or crawl space with a flashlight the next time it rains and try to trace it, but your most accurate answer will come from having a professional come out to find it and give you a quote.

The shingles may not have been properly installed, they could have been placed over an existing layer of shingles that is not giving adequate coverage, or there could be new damage due to a recent storm. The best way to find out is to have an inspection and estimate done.

The answer depends on several factors, such as what is causing the leak, and the overall age and condition of the roof. If the leak is caused by a few minor issues with the shingles or flashing, this can be repaired easily in a few hours. However, if the roof is old and subject to widespread problems, it may need to be replaced, which could take a few days.

While it is technically possible to layer one set of shingles on top of another, this may be setting you up for future problems. If your current shingles are curling, cracked, missing, or are covered with moss or algae, you will need to strip them to install the new roof. Likewise if you already have two layers on your roof, they will have to come off to install the new shingles.

Every roof is different, as well as what the roofers will find when they get up there. It can take anywhere from a few hours to a few days depending on the size and the scope of the job.

A roofing underlayment is also known as felt paper, and is installed beneath your shingles, over the wood of your roof. It helps protect your roof from wind driven rain that can get beneath your shingles and potentially damage your home.

If the wood beneath your shingles shows signs of water damage, it will need to be replaced as well.

The type of roof that you get should complement the rest of the style and features of your home. You should also take into consideration the material, how long it lasts, and the costs to make this personal decision.

Be sure to get a detailed quote from your roofer, and make sure it shows everything that was discussed on it. You should also ask for referrals and speak to some former customers. Make sure that the roofer cleaned up after themselves, finished the job when they said they would, addressed any issues in a timely way, and kept to the contract. Make sure that you trust whomever you hire to do the job correctly the first time.

New replacement windows fit properly because they are custom made to fit the existing opening. New windows give your home added beauty, security, and energy efficiency. You will see a significant savings in your energy bill in the very first month after replacing your existing windows with new, energy efficient replacement windows.

No. Special consideration should be given to glass options such as tempered glass, Low-E glass, Argon gas, Krypton gas, and heat mirror. Each option offers various levels of energy efficiency and safety.

We believe that a manufacturers faith in it’s own product should be reflected in their Product Warranty. Simply put, if the manufacturer believes in its own product, that product should have a great warranty. All windows installed by Northern Virginia Roofing are covered by full manufacturer warranties along with our own workmanship guarantee.

There are four basic materials used in making windows: aluminum, wood, fiberglass and vinyl. While all offer different benefits, you’ll want to choose the one with the best thermal performance characteristics, the longest warranty, and the window that looks best on your home. Aluminum windows are inexpensive, but are poor insulators. Vinyl and fiberglass windows offer good energy efficiency, but durability can be an issue. Traditional wood windows are beautiful, but require maintenance. The Andersen windows installed by Northern Virginia Roofing offer the best of all worlds, combining the beauty of wood with the energy-efficiency of advanced insulation.

Seventy percent of an average window is glass; therefore, your biggest opportunity to save on energy comes from the glass. Remember, however, that the frame still makes up 30% of the window. Quite often, a replacement window will feel drafty around the edges. A frame that lacks insulating value generally causes this problem. That’s why every window we install includes a frame that has superior insulating performance.

The quality of any product is only as good as its installation. An improper installation could reduce the energy efficiency of the window, do structural damage to your home, and even void the manufacturers’ warranty. Our installation experts are trained to do the job right the first time. This ensures maximum performance from your windows and eliminates future problems. From start to finish, we guarantee you will be satisfied with your installation experience.

While it’s tempting to think this is a job you can put off or do only periodically, you should be cleaning your gutters about twice a year on average. This can vary depending on the region that you live in, however; houses surrounded by pine trees may need cleaning more often simply because pines shed year round.

Aluminum gutters have some of the longest life spans of modern gutters. It is not unusual for most aluminum gutters to last a minimum of 20 years; if you maintain them well they can last as long as 40 years.

Vinyl gutters have a shorter lifespan than metal gutters. Well maintained they can last 10 to 20 years, but may cheaper versions may not last this long.

Steel gutters have a very variable lifespan depending on how well they are maintained and how often you paint them. 10 years is a reasonable lifespan for most steel gutters, but some can last as long as 20 years.

There are essentially two types of gutters: seamed and seamless. Seamed gutters are made up of separate pieces that either overlap one another or are soldered together at the joints. Seamless gutters are made of one long piece, designed just for your home. They may be more expensive, and most be installed by a craftsman, rather than a DIY installation.

In a way, yes, simply because they don’t have weak spots that could eventually lead to leaks, rust, corrosion and other issues down the road.

Downspouts are installed at the end of gutter runs and direct the water away from your home. You should have one downspout installed for every 20 to 30 feet of gutter.

It depends on what type of gutter hanger you are using. Hidden gutter hangers need to be installed roughly every 36-inches around your home. If your gutters are larger or heavier, you may need to have them placed more often to accommodate the load. Vampire gutter hangers need to be hung every 24-inches around your home.

Leaf screens aren’t just for leaves, so even if you live in an area without a lot of trees, you can still benefit from using them. They can help keep out things like pine needles and other debris that can clog your gutters and shorten their lifespan.

If your gutters are made of steel or vinyl, chances are that you will need to replace them eventually. Some signs that they are ready for replacement include rust, or orange spots showing up on the surface, cracks and holes in the gutters, or gutters that are beginning to warp, sag, and pull away from your house. If you notice that your gutters are beginning to leak at the joints as well, this can be another sign that you need to replace them.

Signs of siding that is beginning to go bad include things like fungus, separation at the seams, warping, and moisture appearing on the inside of your home. If you have vinyl or aluminum siding, individual planks may need to be replaced if they are severely dented or cracked.

Often siding problems only affect a small portion of the planks. This is particularly true for vinyl and aluminum siding, but can also be true for some wood siding installations as well. In many cases, individual boards can be removed and replaced without disturbing the ones around them. Keep in mind, however, that it can sometimes be difficult to match color on the new planks to the old ones.

The best siding for your home will be dictated by a number of things such as your neighborhood association, the type and age of your home, and what your neighbors have installed. It can also be affected by your maintenance needs and budget.

The length of time your new siding will take to be installed depends largely on the size of your home and the type of siding you have. Vinyl siding can go up in about two days, while some types of wood siding can take as long as 2 weeks. Remember that it will also take time to remove the old siding, and replace the house wrap if necessary, and that if you are having wood siding installed, that this will need to be painted, which can add to the timeframe.

Sometimes installing the new siding may cause things to rattle and shake indoors, which may shift some pictures on your walls. Otherwise, it should be fairly uninvasive.

No, vinyl does not offer insulating value unless you have insulation installed along with it.

Yes, all fiber cement products do need to be painted, however some types of Hardiplank can be ordered with the color already applied to the planks, which can save time at installation.

Ideally, no; only as much siding as can be replaced in a reasonable amount of time should be removed from your home during the installation process. This way, if the job needs to be continued over several days, your home is not left bare to the elements.

Removing all of the old siding is not always necessary when your home is being resided. It depends on what has been previously installed, what you are having installed now, and what shape your siding is currently in.

There can be a lot of reasons why a roof can begin to leak. You may be missing a shingle, or there may be a cracked or damaged shingle that is allowing water in. You could also have water infiltration from a chimney or skylight. In fact there can be several reasons why your roof is leaking that have nothing to do with the roof itself and everything to do with the ice dams, soffits, and windows that may be adjacent to it. The only way to find out for sure is to have a professional assessment done.

Not necessarily. In fact, up to 90% of roof leaks are due to penetrations in the roof such as chimneys, skylights, and ridge caps. If the leak is coming from the shingles, it could be as likely to be due to one or two being missing or damaged as it is due to more widespread damage.

If the leaky roof is caused by localized damage, then replacing or repairing the shingles or flashing in that area is the most common leaky roof repair. If the damage is more widespread, however, or is contained to the field of shingles and not to a ridge cap, chimney, skylight, soffit, or other roof penetration, then partial or complete reroofing is the answer.

It depends. If the rest of the roof is in good condition, but you had a missing or damaged shingle that was causing the leak, then the roof will more than likely not need replacing. If, however, the problem is widespread and the roof has reached the end of its lifespan, then yes; the leak could be an indicator of a bigger problem that will result in a total or partial roof replacement.

If there is widespread damage or decay to the shingles, blistering, multiple missing, cracked or curling shingles, or significant amounts of damage then the leak is probably an indicator of a bigger problem that will need to be addressed.

It depends on the problem. If the leaky roof repair is localized to one area and just involves replacing a few shingles, it could be done in less than an hour. If the entire roof needs to be replaced, this could take longer depending on the number of layers of shingles present on the roof, whether you are having the old roof removed, the size, and the pitch of the roof.

Your best bet is to wait for a rainy day and check in the attic to pinpoint the exact place of entry. Remember, though, that in the case of leaky roof repair, the area leaking may not be the only place that has been damaged and that needs to be repaired to prevent future leaks.
