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.

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.

Anatomy of a Roof Leak

No one wants to hear that dreaded “drip drip drip” that means you’ve got a roof leak. Or looking up and suddenly seeing a big dark spot on the ceiling. But when you do, your first thoughts are probably “how did this happen?” and “where exactly is this coming from?” Understanding the answers to these two questions is the key to getting your roof leak fixed quickly and efficiently and also to possibly avoiding them in the first place.

How do roof leaks start?

Typically, a leak will start one of two ways: damage or deterioration. However, there are many different types of both damage and deterioration that may have occurred and that might not be immediately obvious. Here are several that are common for homes in the Hampton Roads area.

Storm Damage

This likely is the most obvious source of a roof leak and also one of the most common in the Tidewater region. Thanks to hurricanes, nor’easters, snow storms and torrential rains, there are myriad ways a Hampton Roads roof can be damaged. But storm damage isn’t always as obvious as a giant tree falling through your roof. Sometimes damage can occur that isn’t noticeable right away. Hurricane force winds can blow flashing off a house, which can eventually lead to water damage and leaks. Winter storms can cause limbs heavy with snow or ice to drop onto a roof and cause a hole that you aren’t able to see or hear right away. Torrential rain can cause gutters to overflow and damage roof decking.

Your homeowners insurance may cover this type of damage, but you have to identify it and file your claim in a timely manner. This means that after each major storm, you should visually inspect your property for any damage on both the inside and outside of your roof. If you believe any damage may have occurred, you should call a licensed roofing company to come and physically inspect and provide any estimates needed for insurance purposes.

Clogged Gutters

Clogged gutters are a common cause of roof leaks, but they are also one of the most preventable. When gutters are clogged, water can build up on the roof, getting under the shingles and causing water damage that could eventually lead to a leak. If you notice dark spots on your ceiling near the outer edges of the house, this may be a gutter issue. Cleaning your gutters (or having them cleaned by a professional) 3-4 times a year is the best way to avoid this issue altogether.

Condensation

Believe it or not, a leak can start inside your home, without the exterior of your roof being damaged at all. That’s because condensation build up in an attic can cause interior leaks. This happens when there is not proper ventilation or proper insulation that would prevent extreme temperature changes – something that is not uncommon here in southeast Virginia. In addition to causing leaks, this condensation build up can also be the source of mold and mildew. Ensuring proper ventilation and insulation is installed in your attic and along your roof line is critical to avoid this type of leak.

Missing or Damaged Flashing

Flashing is just as critical to the integrity of your roof as shingles. Flashing is the metal that covers joints and seams on a roof, and when it is not installed and sealed properly, water can enter and damage the roof decking. If flashing isn’t well attached, it can move or get blown away during a storm. It also ages just like shingles, so corrosion or cracks in the metal could also allow water to enter your home. If some of your flashing is visible from the ground, inspect it after every major storm. However, some flashing may be difficult to see or access and in those cases, a licensed roofing contractor can inspect those areas if you believe there is an issue.

Deterioration

If your roof is nearing the end of its lifespan, it may be deteriorating and causing leaks. Every roof has a lifespan, although that number can vary greatly depending on the material used. For traditional asphalt shingles, 20 years is usually the lifespan. Fiber cement shingles can last closer to 30 and metal roofing can last for 50 or more years. As roofing materials age, they can become brittle and shingles may crack or warp, allowing water to get underneath. They may also fall off more easily – even during a less than severe storm. If you know your roof is nearing the end of its life, it’s better to replace it before a leak causes interior damage, requiring you to repair multiple areas of your home.

What to do when your roof starts leaking

When a leak occurs, it’s time to bring in the professionals. Roof repair can be dangerous for the average DIY’er and if not done properly, can cause more damage or void material warranties. Instead, research your local roofing contractors and find one with a good reputation in your community. The sooner you contact them, the less damage the leak can cause, so don’t put this task off.
