Roof flashing is an essential way to prevent leaking through your roof. The flashing acts as a sealer between the joints in the roof.
Certain areas of your roof and walls are more susceptible to leaks and water damage. This is definitely true in the case of a dormer wall, roof valleys, skylight edges, and the chimney. Wherever water runoff is heavy or where two surfaces meet, they will need roof flashing.
MATERIALS USED FOR FLASHING
Popular materials used for roof flashing include galvanized, copper, and aluminum. Galvanized sheet metal is the most common material. DIY homeowners use aluminum flashing.
ROOF FLASHING TYPES
Flashing is most often formed through soldering, though there are a variety of different kinds of roof flashing. Chimney flashing will be used at the base of the chimney in multiple parts. There will be flashing around the bottom and sides and finished with saddle flashing around the top. Additionally, flashing is around the chimney. A cap flashing goes over the edges of the rest of the flashing to keep water out.
Step flashing is at a vertical wall or a sloped roof. Drip edges will stop any water from trying to seep underneath the roof around the eaves. Integral flashing is around skylights. Step flashing is around the base, the sides, and saddle flashing around the top.
The most common areas leaks occur are where pipes penetrate the roof surface or in valleys. Seal these areas with special asphalt roofing cement. In order to prevent leaking around areas with pipes, one should invest in vent pipe flashing.
Install flashing at your home’s most vulnerable areas. Damage occurs in several ways. Cracking and warping happens.
Flashing may become damaged because of poor installation, sloppy repairs, age, and exposure as well as weather related issues.
