What you Need to a Know About Roof Flashings
Flashing is a little known material to most homeowners, but it is the most important material in preventing roofs from leaking other than the roof material itself. Roof flashing is the material you see if you look at the joint where a roof meets a chimney. Roof flashing is a thin piece of material that professional roof contractors will install to divert water away from areas that are prone to heavy water runoff or where water sits. Flashing is installed to cover different roof penetrations that you may have whether that be skylights, chimneys, or vents. If flashing is not covering any of the areas mentioned, you as the homeowner are going to have endless leakage throughout your entire house.
- Ridge flashing- The ridge is the stretch of the highest most point of the roof, flashing on this point of the roof will protect
- Drip edge– Installed along the eaves of the roof (where the roof overhangs the siding of your home) , this will prevent water from forcing its way up the edge of the roof and underneath the shingles.
- Vent pipe flashing- Vents are one of the major weak points for roof leaks when no flashing is installed. This type of flashing will sit at the base of any and all ventilation pipes sticking out of your roof and prevent water from seeping through.
- Step flashing- If you have a chimney in your home, it is necessary for step flashing to be installed to keep a constant flow of water where it connects on the roof.
- Valley flashing- A roof valley is where two sloped roofs meet and commonly subjected to a high water traffic area during a rainstorm. If not installed properly, the water speeding down your roof will corrode the shingles on your roof which will cause roof leaks and headaches for you as the homeowner.
