What is Roof Flashing and Why is it Important?

A roof's most important job is to keep us dry, which is why we're always surprised when it suddenly develops a leak, as though it should just do its job forever!

What is Roof Flashing and Why is it Important?

Roof Flashing

One of the most important features of any roof when it comes to preventing leaks is its flashing. In fact, the major cause of roof leaks is a fault in the roof's flashing. What is roof flashing? It's simply a sheet of galvanized metal or aluminum that is installed wherever parts of your roof intersect, penetrate, or meet the walls of the house. For example, you'd put flashing around your chimney, which penetrates through the roof, and you'd also put flashing where the garage roof meets the house.

How Flashing Works

Roof flashing, when properly installed, works with gravity to direct water away from walls and seams around roof projections and on to the regular roofing materials where it is directed to the ground. Effective roof flashing must be durable, weather-resistant, and able to move as the roof expands and contracts with the weather and the seasons.

Roof Flashing is Not a DIY Job

Roof flashing is, in most cases, one of the most technical and difficult parts of a roofing system, and professional roofers often cut and shape their own flashing to work precisely with the idiosyncrasies of each roof. Because any roofing job is only as good as its weakest link -- and flashing is a roof's weakest link -- installing it is a job best left to the professional roofer.
