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.

Common Roofing Storm Damage

If you watch the local news or even just tune in for the weather forecast, you know that we’ve reached peak hurricane season and that the tropics have been very active thus far.

Fortunately, the Mid-Atlantic coast including Southeast Virginia and Hampton Roads have been spared from any direct hits. But there are still two more months of hurricane season, and now is the time to be prepared for anything that may come our way. Not to mention that as soon as hurricane season is over, nor’easter and winter storm season will be upon us.

When it comes to your home and your home’s roof, there are plenty of things you can do in advance to avoid certain types of damage during storm season. But there are some things you simply can’t prevent from happening, and being responsive after the fact is the best you can do. Here are a few common types of roof damage to keep an eye out for as we weather hurricane season this fall.

Tree Damage

Tree damage isn’t always as obvious as an entire tree crashing through your roof and into your home. Some tree damage can go unnoticed until it causes interior damage – days, weeks or even months later. A stray limb with enough wind and force behind it can cause shingles to fly off, roof sheathing and decking to be pierced and make your roof vulnerable to leaks.

Tree damage can even come from overhanging branches that simply rub along shingles and cause unwanted wear and tear. It’s always a good idea to keep low hanging or potentially destructive branches trimmed back from the roofline where possible.

After a storm, visually inspect your roof as well as you can from the ground to see if any limbs, branches or even leaf buildups can be seen. If so, they should be removed immediately and the roof should be inspected to ensure no damage was caused. If damage was caused, a roofing contractor will typically be able to do a repair confined to that area without a major overhaul of your roof.

Loose or Missing Shingles

Perhaps the most common damage after a storm is loose or missing shingles. While it may not seem like a big deal if one or two shingles come off, their absence makes the shingles all around that area more susceptible to blowing off, and jeopardizes the roof sheathing beneath. Depending on when and how your roof was installed, the material manufacturer or installer may have specific warranties to cover shingle replacement. In any case, the shingles should be replaced as soon as possible to prevent further damage.

Loose or Missing Flashing

Flashing is the metal sheets that are used in roofing around joints in a roofline and around other roof penetrations such as pipes, chimneys and vents. They play an important role in protecting your roof decking and if jeopardized, major interior damage can occur. Loose flashing can actually cause quite a bit of damage to the rest of your roof, tearing up or removing shingles around it, especially in a wind event.

Missing flashing can allow water intrusion and will also make it easier for nearby shingles to be blown away. Some flashing you may be able to visually inspect from the ground, but if you have reason to believe that flashing may be loose in spots that you’re not able to inspect from the ground, call in a qualified roofing contractor to inspect for you – don’t risk causing damage to yourself to find damage on your roof.

Clogged or Broken Gutters

Particularly if you live near a lot of trees, storms can cause debris to fly off of nearby vegetation that can eventually land right into your gutters. This debris will cause your gutters to work less effectively, which means water will build up and potentially seep up underneath your shingles and sheathing, causing damage to the roof decking below, often seen as dark water spots in the corners and along the top of the walls in your home. Ideally, have your gutters cleaned before storm season so that they are cleared and ready to carry all that stormwater away from your home. But it’s also a good idea to check on them after a storm and make sure nothing has caused any clogs or damage to the gutter itself.

Broken or loose gutters are also common after a storm, and if you see evidence of that, call in a licensed contractor to fix the problem before the next rain event occurs. Broken gutters can funnel water into places it should not go including near your home’s foundation and onto walls and windows, causing even more damage. If you don’t have gutters, or your home’s gutters need to be replaced, you may also want to consider installing a Rapid Rain ™ gutter system which is designed for high capacity that comes with living in a storm prone area.

Roof Maintenance Tips for Stand-Alone Structures

When you think about roof maintenance, your mind probably goes right to the largest roof you have to deal with – the one over your home.

But if you have any exterior stand-alone structures on your property, their roofs need to be inspected and maintained just like your home’s. This may include garages, sheds, pool houses, barns or workshops. It’s particularly important to keep an eye on these structures if they store expensive equipment or other important items to avoid any type of damage.

The roof on an outbuilding can experience additional challenges that your home’s roof may not have, and there are additional ways to inspect and maintain these structures. Here are a few of our tips for maintaining and extending the life of your stand-alone structure’s roof.

Regular Visual Inspections

Like your home’s roof, you should inspect the roofs of these structures on a regular basis and especially after storm events. Depending on the size of these structures, it may be a little easier to visually inspect their condition from the ground. Look for the same telltale signs that you would on your home’s roof: missing shingles, warped or algae covered shingles, loose or missing flashing, clogged or damaged gutters and of course – holes or other damage. Check the eaves for nests of any kind – birds, bees, wasps, squirrels or any other type of animal nest can cause serious damage.

Safely Clean Them from the Ground

Again, the roof line of these structures may be a bit lower which may make it possible to safely clean them off yourself. A buildup of leaves, moss, or a few sticks and branches may seem benign, but they can cause damage if left alone for too long. Moss and algae – which are common in the Hampton Roads region – can collect on areas of the roof that do not get much direct sunlight. If they aren’t dealt with, they can weaken your roof over time.

If the roof is low enough and you have a strong enough hose, the first cleaning approach may be to simply spray it down to remove debris and build up. If that doesn’t do the trick, you can invest in a soft bristled roof rake which can be used from the ground to rake off debris and even some mildew and algae. Make sure not to scrub too hard to avoid damaging any roofing materials.

Remove Potential Hazards

Make sure to keep any nearby trees or bushes trimmed back. Limbs and branches that lean or hang over your outbuilding could cause extensive damage over time from friction or in an instant during one of our regular southeastern Virginia pop-up storms. If the vegetation around the building is small and light enough, you can take care of it yourself, but if there are any substantial trees or branches that should be removed, always call a professional.

Check Inside for Pests

It’s important to check the interior of these structures regularly. Some roofing issues can’t be seen from the outside. So even if your barn or shed is full to the rafters, make it a point to inspect the interior at least twice a year and after major storm events. The most critical interior areas of these structures may be the corners where animals are most likely to have built nests or created pathways to access the inside. Birds, insects and rats or squirrels can wreak havoc on a roof, chewing through materials or causing damage to rafters and sheathing. If you find anything, get in touch with a professional pest control company or animal control.

Whatever type of outbuilding you may have on your property, it’s likely that it houses something important enough for you to protect. Make sure the roofing on these structures is doing its job as best as possible with regular inspections and maintenance. If you see any signs of damage and believe your structure needs roofing repair or replacement, contact Andrews Roofing today.
