Chimney flashings

One of the more common places for a leak to occur on a roof is around the Chimney. Unless flashed properly your chimney will leak resulting in added expense to repair rot, interior water damage and the actual source of the leak. With every roof system that we install we make certain that the chimneys are flashed correctly using proven techniques endorsed by both the National Roofing Contractors Association.

Be wary of a company that does not specifically detail their flashing procedure with your chimney. Tar manufactures claim tar is flashing. Tar might be useful for a quick temporary fix in an emergency situation, however, it is not acceptable for a permanent application. If an estimate simply states “Flash Chimney” or “Flash Skylight” they will probably use tar on your roof. The lifespan for tar is approximately 5 years. This is a problem if you’re installing a 30 year or better roof system. Plus tar looks horrible.

Most roofing companies do not offer a properly flashed chimney. It involves masonry work that novice roofers are not accustomed to. A properly flashed chimney using lead, aluminum or copper will outlast your asphalt roofing materials.

Make sure to ask questions to avoid headaches. Never let the low ball roofer convince you tar is ok. It’s not and it will cost you in the long run!
