Although your roofing shingles, metal sheets, or clay tiles do most of the work to protect your home from the elements, there is another less familiar part of your roof that works just as hard—roof flashing. If your roof flashing is not working properly, you will have a severe problem with roof leaks.
Roof flashing is a thin roll of metal that reinforces roofing applications and wall joints to prevent water from leaking into the house. Roof flashing can be made of various materials, including copper, aluminum, galvanized steel, or lead. It is supposed to be completely resistant to moisture. To prevent moisture problems in your house, you have to make sure your roof flashing is working properly.
Here are simple ways of maintaining your roof flashing.
Locate the Leaks
To fix a faulty roof flashing, you need to locate the leaks. These include leaks around the chimney and corners of your roof. So, keep an eye on your attic to notice leaks before they develop into serious problems. Although there are some leaks that you can fix yourself, most serious flashing installation hitches require professional intervention.
Lock Down Loose Flashing
Roof flashing is likely to become loose over time, possibly due to loose screws that anchor it or deterioration of the metal that locks it down. When this happens, the flashing will become loose or fall off. So, the only remedy is to lock it down afresh with new screws. Make sure that the replacement screws are made of the same metal as the flashing. Screw them into the frame below to lock the roof flashing into place. You should also cover the screw heads with roofing cement for moisture prevention.
Although roof flashing is designed to resist water and other elements, sometimes corrosion or normal deterioration causes openings across the flashing. In that case, you do not have to replace the entire flashing; just cover up the openings. Start by wiping away corrosion and then place a flashing piece on the opening and cover it with roof cement.
Refill the Chimney Flashing
Although roof flashing is usually attached to the chimney’s mortar to create a waterproof barrier, sometimes this mortar cracks and crumbles. When this happens, you have to refill the cracked mortar with a new layer of roof cement. Ensure that the chimney flashing and the gaps between the bricks are completely covered.
