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. If you’re concerned about your roof receiving ideal ventilation or if you need your roof system repaired or replaced, contact Andrews Roofing Today for more information and to schedule your estimate.

Why You Should Replace Rather than Roof Over Your Existing Roof

If you’ve been in the market for a new roof for your home, you have probably run across the option of roofing over top of your existing roof.

“Roofing over” is a method that leaves the current shingles and roof deck in place, and installs new shingles right over top of the existing ones. Alternatively, reroofing requires removing all existing shingles, doing any necessary repairs or replacement of the roof deck, membrane, and supporting structures beneath, before replacing the shingles with new ones.

Roofing over your roof requires that all the existing shingles are perfectly flat without any curling, that your roof deck be in perfect condition, that there are no leaks or ventilation issues that need addressing, and that the current roofing structure is able to withstand the additional weight of a second layer of shingles. However, if all of these things are true, you may not need a new roof at all. And even if those conditions are in place, a roof over existing roof can appear wavy and uneven. In most cases, a roof over does not make long term sense for homeowners, which is why we do not recommend this to our clients and do not guarantee this type of work.

We should note here that it is possible to roof over certain materials, like membranes that are in decent condition. This is done more often on commercial roofs depending on the core sample, decking, condition of insulation, etc. This type of project is only performed after careful inspection of the flat roof and an analysis and assessment of the materials and decking beneath the membrane.

Roofing over an existing roof is sold to homeowners as a cheaper alternative to replacing their roof. Often times, though, roofing over does not really solve the underlying issues the structure may have and can end up being a more costly option.  If you’re looking into replacing your roof, it’s likely because you’ve noticed leaks here and there, there’s damage to the shingles, shingles are missing or deteriorated or you’re noticing your energy bill is soaring. Putting new shingles overtop of existing ones doesn’t address any of these critical issues on the inside, which means damage may continue to occur. Putting another layer of shingles on top of existing ones that have issues also means it will take more time, money and material to get to and diagnose the problem, and more labor to repair the underlying issues.

Replacing your roof may cost more up front, but the return on investment is higher.

Over the long term, a new roof will look better, last longer, and protect your home better. When you allow a licensed roofing contractor to remove the existing shingles, they can properly assess any other repairs that need to be done to the roof decking, membrane, flashing, structural beams or ventilation systems. Having these issues addressed at that point means the overall lifespan of the roof will be longer. It’s also important to note that some roofing material manufacturers will not warranty a product that is put over existing shingles rather than onto a clean roof deck. While roofing over a roof may be cheaper upfront, the costs of uncovered warranty claims and an overall shorter lifespan don’t pan out in the long run.

Your roof is a major part of your home that you want to look good and function well. When you’re considering your roofing project, consider that your roof literally protects everything in your home beneath it. It’s not the place to cut corners. Before reroofing your home, research roofing contractors in your area, read up on their online reviews and ask around your neighborhood for recommendations. Get quotes from at least two to three reputable companies and research the materials they work with to ensure they are high quality and guaranteed with a manufacturer warranty.

If you live in the Hampton Roads region and your home needs a new roof, contact Andrews Roofing. We’d love to be one of the companies to provide you with an estimate. Our work is always guaranteed, we use some of the best products on the market, and we’ve been providing excellent customer service to Tidewater residents for years.

Should I Worry About Frost on My Roof?

Have you ever walked outside on a cold morning and noticed the frost that covers the ground? You might have to scrape your car before you can drive, and your grass may look like a sparkling wonderland. Direct your view upward to have a look at the roof. Is there frost on it? Do you know whether frost is good or bad for your residential roof? How do you know when to worry?

Is Frost Good or Bad?

The frost itself that collects on your roof isn’t necessarily good or bad. Roofing materials are made to withstand the weather, and roofers who work in cold environments know which materials will hold up best. As long as your roof is in good repair, you shouldn’t have to worry about water damage.

The fact that there’s frost on your residential roof could actually be a good thing. If you look around and notice all your neighboring houses have frost, but yours does not, it could be an indication that your attic insulation isn’t quite up to par. The frost may be spotty, which also means the insulation isn’t properly in place. Without proper insulation, the heat that should be warming your home is leaking out through the attic and the roof, which is melting the frost.

Should I Worry About a Lack of Frost?

If there’s a lack of frost on your roof, there could be cause for alarm. You should only worry if your neighboring houses have the same amount of sun exposure as yours. For example, your neighbor’s house might be blocked from the sun by tall trees or a taller building, while your home is in direct sunlight. As soon as the sun hits, your frost could melt away, but will remain on your neighbors due to the shade. If that’s the case, you would not need to worry.

Contacting a Roofer

If your house is not in direct sunlight, and everyone else has frost, you should contact a roofer to see if there’s a problem with your roofing and insulation. Contact Andrews Roofing by calling 757-296-0553 or emailing us today for more information.

4 Reasons to Be Thankful You Have a Roof Over Your Head

You’ve probably heard people express how they’re thankful to have a roof over their heads, and perhaps you’ve just considered it a figure of speech. In reality, there are a lot of reasons you should be thankful for that roof over your head. It doesn’t just signify the fact you live in a home. The following are four additional reasons to be thankful for your roof.

  1. Home Value

Did you know the appearance of a new roof makes the entire home look newer? Those fresh shingles and the comfort of knowing a new home buyer won’t have to replace the roof any time soon can make the value of your home rise. Whether you’re looking to sell or just want to increase the value of your home, a new roof can help you out.

  1. Protection Against Weather

When your roof is properly repaired and maintained, it serves as protection against the weather. It keeps the cold air out during winter and blocks the heat from penetrating during summer. It acts as a barrier between your furnishings and the rain and stops the sun from fading everything inside.

  1. Energy Efficiency

Depending on the type of roof you have installed, maintenance costs can be cut, and energy costs can be reduced. A properly insulated roof will help ensure the perfect temperatures inside your home don’t literally go through the roof, causing your HVAC system to work overtime. Instead, the roof can help your home stay at a comfortable temperature with minimal effort by the HVAC system.

  1. Prevention of Mold and Mildew

Roofs need to be properly ventilated so moisture cannot thrive inside your home. Condensation that builds up will typically turn into mold and mildew, which are both common causes of a variety of health issues. Your roof ventilation system can help to avoid such issues.

Contact the Professionals

There are a lot of reasons to be thankful this year, and having a roof over your head gives you many reasons to express that thankfulness. Whether you need a roof installed or repaired, contact Andrews Roofing by calling 757-296-0553 or emailing us today!

Top Reasons Roofs Fail

When you install a new roof, the last thing that you want to happen is for the roof to fail. Unfortunately, when a contractor does a poor-quality job, this is exactly what happens. Here are some of the most common reasons for roof failure.

Poor Ventilation

Good ventilation keeps a roof in good health. You should have a ventilation system that pushes heat and moisture out during the summer. This will minimize expansion due to temperature changes. Also, it will keep your attic cool throughout the year.

Poor Installation

When it comes to home renovation, it is important that the projects are finished right. Even with the best materials, if the roof is not installed properly, it is not going to function correctly. You need to ensure that your roof is installed right the first time, by a contractor who knows what they’re doing.

Poor Quality Materials

When it comes to choosing materials, you want to take more than cost into consideration. Even if the low-cost products look appealing, you need to keep in mind that the lower costs can also mean lower quality materials. When you have high quality materials, your roof is more likely to last.

Poorly Chosen Flashing

You need to protect the protrusions where exhaust pipes, chimneys, and dormers connect to the roof. These areas are prone to leaks and other problems. Metal flashings are the best way to seal this area. You do not want to use caulk or any other type of sealant. These products degrade over time.

Roofs can fail for a number of different reasons. If you want to make sure that your roof doesn’t fail, then you’ll have to invest in regular maintenance and inspections. The higher quality the job, the more likely you are to have a roof that lasts. For a roof that will last, call a company you can trust.
