Why Does Roof Flashing Fail?

Flashing is a flat and thin material used to prevent water, whether from rainfall or melting snow, from seeping through the cracks and openings of a roof. It is commonly installed around vulnerable areas of the roof such as vents, chimneys and skylights. In this article, shingle roof replacement experts discuss how roof flashing fails and why it happens.

Wrinkled Flashing

A piece of metal flashing that has wrinkles in it is often the result of weathering, which refers to the effects of long-term exposure to the local climate. Extreme, varying temperatures in the local area can cause severe warping through frequent contraction and expansion of roofing materials, creating a wrinkled appearance. As the metal begins to wrinkle, its length is shortened, exposing parts of the roof during the next rainstorm. Be sure to call in a professional to patch up or replace wrinkled flashing in order to ward off leaks and other structural problems.

Loose Flashing

When a home has foundation issues, cracks are not always readily visible. Many homeowners will notice them around door frames or near the roofing structure rather than at the base of the foundation itself. According to an emergency roof repair specialist, these cracks are tiny stress fractures that resulted from settling. The settling of the foundation is what prompts the flashing to become loose.

From time to time, be sure to inspect your roof from the ground up. If you notice flashing pulling away or, in some cases, separation of the chimney from the house, there is a great possibility that your home might require the assistance of a foundation expert.
