Why Roof Flashing is So Important

The roof of a home isn’t one piece, it’s a combination of multiple parts that work together to protect your home. One of the most important pieces of a roofing system is the flashing. But why is it so important and why do all roofs need it?

What is Flashing?
Without flashing, water could easily get underneath the roof shingles, causing water damage, rot, and mold. Roof shingles are the first line of defense against the elements of Mother Nature, while flashing is the second line of defense waiting to stop any and all precipitation. A well-installed roof without the proper flashing needed will compromise the entire roof.

Where is it Installed?
Flashing is installed at every roof intersection, surrounding the chimney, around roof ventilation, and along the eaves of the roof. Shingles can not provide an airtight fit when other surfaces intersect them, so another piece is needed to guarantee no water makes its way into the structure of the roof. Most flashing is installed before the shingles so it can lie flat on the roof.

Flashing Repair
Roof shingles can last anywhere from 15 to 100 years depending on the type of material used and the quality of the installation. Unfortunately, flashing doesn’t always last as long as shingles and will sometimes need to be replaced before a full roof replacement is necessary. Make sure you check all of the flashing during your routine roof inspections.
