When most people think about roof leaks, they're imagining damaged shingles where water is getting through the roof. While many roof leaks do start this way, it is even more common for water to take a different route getting through the roof. Every roof has it's vulnerable areas such as the area around the chimney and vents or the area where two roofing planes meet. At these vulnerable places, an extra layer of protection known as flashing is placed beneath the shingles to keep out any water that might get beneath the shingles. The flashing is designed to direct water to the rain gutters where it can get off of the roof safely.
Unfortunately, over time the flashing, and even the chimney itself can begin to deteriorate allowing a way in for water. If water is getting into your home, your flashing is a good place to start looking for the leak. Many roof leaks could be prevented by regularly inspecting and maintaining the flashing on your roof. When it does become compromised, the flashing should be repaired or replaced to prevent roof leaks. Here are some tips for taking care of your roof's flashing.
Taking care of your roof's flashing
Flashing is usually made of overlapping layers that can consist of aluminum, sheet metal, copper, or some other kind of metal. While the metal flashing itself can actually deteriorate over time, most of the time the problem is the sealant used in the installation of the flashing. If the seal becomes compromised, the most vulnerable parts of your roof can develop leaks. This is especially true in colder climates where freezing temperatures can cause the sealant (such as caulking or roofing cement) to contract and then expand in warmer weather. To prevent leaks like this from occurring, a better type of installation of the flashing is needed. If the flashing is imbedded in the mortar joints, even the expanding and contracting of the roof during the winter won't compromise the flashing.
Fixing the problem
Whether you've spotted a leak in your home or not, it's always a good idea to periodically inspect your roof. While you may be able to spot damaged shingles from the ground with a pair of binoculars, you'll want to actually get on your roof, or hire someone to do it, to get a close look at the flashing. If it's compromised, you know it's time to bring in a roofer to fix the problem. When having the flashing repaired or replaced, it's a good time to make it's done right.
If the flashing and the shingles are all intact, the problem may be with the chimney itself in which case a mason should take a look and repair any damage to the chimney. By taking care of your roof's flashing and chimney, you protect the most vulnerable parts of your roof.
