Flashing Repairs

Many roofing companies in Denver are aware that the majority of roof repairs are flashing related. A 1/8 inch flashing error is all that is needed to result in a roof leak. If this occurs at a point above a chimney, wall abutment or anywhere on the roof where the natural flow of large volumes of water is interrupted, a heavy rain may cause water penetration and interior damage. Chimney flashing, step flashing and head wall flashing are some of the first places we check for leaks. We replace flashing that has been damaged or become unsealed over time. These areas are then sealed and shingled.

Skylights are a common source of leaks. They add wonderful natural light to a room, but need to be properly maintained. We find older or improperly installed skylights that need to be re-sealed or completely re-flashed.

Pipe jacks are another common roof component often needing replacement. Over time, the sun can deteriorate the rubber on the three in one boots causing them to crack. These need to be replaced completely. We have even been called out to one house where squirrels had completely eaten the lead pipe jacks down to ½ inch from the surface of the shingles!

As a Denver roofing company, we have conducted repairs in which there is missing flashing and in some cases, flashing that has been manipulated or eaten away by birds, squirrels, rats or other furry critters seeking refuge from the elements. Wildlife is wonderful to enjoy, but not in one’s attic. We don’t address the animals, but we do fix the flashing issues that allowed them access in the first place.

Another common repair location is in the roof valley. If ice and water shield was not installed properly (or at all) in the valleys, leaks may occur.  Ice and water shield is a critical component for roofs in our area and is a code requirement by some building departments. When we encounter a leak in a valley, we remove the valley shingles and correctly install the right combination of ice and water shield and valley metal, and then re-shingle the valleys. This is the best repair method, however, there are times when the homeowner insists on only applying tar to the surface of the valley because of budget restraints.
