Sometimes, even the steepness of the roof can affect the price of a flashing repair as well, so keep that in mind. The number of shingles to replace and the length of the roof valley will affect the overall cost. A repair-person has to remove the shingles around the flashing, fix, or replace, and seal the flashing itself, then replace the shingles. You might also only be looking to replace the flashing around your chimney, which would cost you anywhere between $200 to $500.Ī replacement may seem somewhat pricey, but you have to keep in mind that it isn’t just the flashing that’s being taken care of. A total flashing replacement might cost anywhere between $300 to $600. Generally, the cost of fixing flashing is anywhere between $15 to $25 per linear foot, which includes both the price of the new flashing itself and the caulking used to seal it in place (which is about $10 on its own or sometimes more). An inspection of your flashing might reveal a minor problem with one area of your flashing or may find the entire strip has corroded over time. It can develop cracks and leaks over time as the elements wear them down. The flashing redirects water to your gutters, but if the flashing fails to hold up, that water will seep into the roof and cause water damage to your interior.įlashing is one of the most vulnerable areas of your roof. The flashing is a metal or vinyl strip on your roof that blocks water from entering through skylights, roof valleys, and the area surrounding chimneys.
FLASH A ROOF PROFESSIONAL
Call a reputable roofing professional who is licensed, bonded and insured, and who is experienced roofing in your area and climate.If you’ve noticed a water leak in your house, you may have a problem with your roof flashing. Installing flashing isn’t a DIY project, unless you’ve had plenty of training. A reputable roofing professional should be able to draft plans that will protect your roof during this process.įinally, and perhaps the most critical element, poor installation is most often the cause for flashing failure. In addition, flashing failure can also occur when the original roof specs are unavailable during a roof replacement or repair. This is particularly true around vertical dormers, second story walls, parapet walls or any vertical surface on the roof. This can cause the flashing to pull away from the surface and no longer protect the areas it is supposed to. However, climate (especially the hot and varied climate of the desert southwest) can cause all kinds of failures in this otherwise perfect system.Īlternate freezing and baking temperatures can cause dimensional changes in the roof structure as wood and material shrink or expand. Properly installed flashing works with gravity to help shed water onto the regular roofing materials when it is then channeled harmlessly to the ground. The number one cause of leaks in any roof is faulty roof flashing. The metal sheeting is placed over joints, around chimneys, fan and plumbing vents and stacks in the roof to prevent water seeping below the roofing material and into the building. Roofs on commercial and residential property serve one main purpose … to keep the weather outside! Roof flashing - pieces of sheet metal, aluminum or galvanized steel - act as a last line of defense against water leakage.
