DIY Roof Maintenance Tips Every Homeowner Should Know

Your roof is one of the most critical components of your home, protecting it from the elements day in and day out.

Regular maintenance can extend its lifespan and prevent costly repairs down the road. For serious roof repairs, a professional roofing contractor should be called in, as the work requires expertise and can be dangerous for a weekend DIYer. However, there are some essential roof maintenance tips that homeowners can do safely on their own to prevent damage and decay.

Make Inspections a Habit
Create a regular monthly or seasonal habit of visually inspecting your roof. You can time it with Easter, July 4th, Halloween and Christmas to make it easy to remember. Look for signs of damage such as missing or damaged shingles, cracked caulking, or rust spots on metal roofs. While we do not recommend tackling those repairs yourself, the earlier you identify them and get a professional involved, the less damage (and cost) you will incur.

Clean Gutters and Downspouts
Clogged gutters and downspouts can lead to water damage and roof leaks. Clear them of debris like leaves and branches to ensure proper drainage. This is especially important as fall winds down and again in the spring before summer storms begin. If you feel comfortable, you can use a ladder and gloves to remove the buildup manually, but always have someone nearby to steady the ladder and assist as needed. You may also want to invest in gutter guards for easier maintenance.

Trim Overhanging Branches
Overhanging branches from nearby trees on your property can scratch and damage your roof during windy conditions. Trim back any branches that come into contact with your roof to prevent this from happening. It will also reduce the risk of fallen branches causing severe damage during storms. If the branches or trees are very large, you don’t have the required tools or simply don’t feel comfortable tackling this yourself, call in a professional tree service, who can take care of it quickly and safely.

Check for Signs of Water Damage
Water stains on your ceiling or walls are clear indicators of a roof leak. If you notice any signs of water damage inside your home, inspect your roof immediately to identify the source of the leak. This can be done safely by inspecting your roof from your attic. Look for damp spots and moisture on the underside of the roof deck and even eroded insulation. Addressing leaks promptly can prevent mold growth and structural damage.

Repair Flashing
Flashing is the thin metal strips installed around roof penetrations such as chimneys, vents, and skylights to prevent water infiltration. Inspect the flashing for signs of damage or deterioration and repair or replace it as needed. Properly sealed flashing is essential for maintaining a watertight roof, and flashing damage is often the cause of a leak, rather than the roofing materials.

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.

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.

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.

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.

Where is That Roof Leak Coming From?

If your roof is not well-maintained, there is a whole list of issues that could occur, including structural damage and unhealthy mold growth. If you have noticed water stains or actual water coming from the ceiling, you might have a leak. Immediately repairing leaks is essential to keeping your roof in the best condition, but how do you know where the leak is coming from? The following are some common problem areas you can check to find your residential roof leak.

Shingles and Other Materials

The actual shingles or other roofing materials on your roof could have damage that is allowing moisture into your home. Damaged shingles will be buckled, corroded, cracked, or missing all together. You could also look for granules on the ground surrounding your home or nails that are missing or backing out. If you have trees that hang over the roof, be sure to check those areas, as a swaying branch could easily wear out your roofing.

Flashing

The point of flashing is to guide water in another direction when it wants to seep down into a seam on the roof. Flashing is located around chimneys, vents, and other areas where there’s an intersection or an angle in the roof. When flashing is not properly installed or sealed, water will begin to flow underneath and damage your home. Look for loose flashing, ripped pieces, or missing areas.

Skylights and Chimneys

The more extra features you have on your roof, the more chances water has to get in. Skylights and chimneys can be both functional and aesthetically appealing, but without proper installation, it’s easy for water to penetrate the roofing materials surrounding them. You should have a professional look at the seams and the installation to make sure it is all sealed correctly.

Hiring the Professionals

If you’re worried about a leaky residential roof, it’s important you contact the professionals for an inspection. Contact Andrews Roofing today by calling 757-296-0553 or sending us an email to learn more.

How to Reduce the Risk of Fire Damage

Your roof doesn’t just finish off the look of the house. It protects you, your family, and your belongings. If your roof becomes damaged, it is not going to provide that protection. The following are some measures to take to reduce the risk of fire damage to your roof.

Use Fire-Resistant Materials

When your roof is installed, speak with the contractor about the type of roofing materials being used. If it costs a little more to get a higher-class material, it is often worth the investment. Class A roofing materials are the most fire-resistant, followed by Class B, then Class C, which are each less resistant than the one before. There are also unrated materials, which are the least resistant to fire.

Repair Holes and Gaps

Fire-resistant roofing materials will begin the job of protecting your roof against fire damage, but you should also have holes and gaps repaired. Damaged areas of the roof won’t have the same protection as other areas. Whether you’re missing some shingles or have a gap in your flashing, a fire could sneak through those damaged areas and into the less protected areas underneath.

Regularly Clean the Roof

Fire-resistant roofing materials doesn’t mean fireproof. If you have a lot of debris collected on the roof and it begins to burn for an extended period of time, the heat could eventually get to your roofing materials and ignite them. Any time debris falls on the roof, due to the change in seasons or the change in weather, be sure it gets cleaned off.
