Understanding Different Types f Roof Flashings in Lawrence, KS

by | Feb 15, 2018 | Roofing Contractor

There are some areas of residential roofs that are more prone to water damage and leaking than others. Areas such as intersections between walls and the roof’s surface, those surrounding chimneys or skylights, roof valleys, and just about anywhere that two opposing surfaces meet on the roof require a little bit of extra protection in order to prevent water damage. That’s where Roof Flashings in Lawrence KS come in.

What is Roof Flashing?

There are several different types of roof flashing, but all of them are made from water-resistant materials such as roofing felt, rubber, plastic, or rust-resistant metal. Galvanized steel is by far the most commonly used material for fabricating roof flashings, although aluminum and copper are also appropriate for certain special situations. These materials must be custom-formed into the right shape prior to being applied to the roof.

Chimney Flashing

This form of roof flashing is applied around to various areas of a home’s chimney to prevent water leaks. Continuous flashing should be applied along the bottom of the chimney, while step flashing is used up the chimney’s sides and saddle flashing or cap flashing can be applied at the top.

Continuous Flashing

There are several uses for continuous flashing; it’s not just used for chimneys. This type of flashing is used to protect any joints between vertical walls and sloped roofs.

Drip Edges

The purpose of drip edges is to prevent water from seeping in along the edges of eaves and rakes. This form of roof flashing is applied beneath roofing felt when it is used to protect eaves, and over it when it is used for rakes.

Valley Flashing

This form of flashing is used to protect the valleys in roofs that form where two planes meet. They are fabricated as w-shaped channels, which should be placed between the roof’s building felt and its finishing material.

Step Flashing

The purpose of step flashing is to protect areas where the roof meets chimneys, skylights, and the side walls of dormers. It is fabricated from right-angled metal pieces, which are worked into the shingles so that they overlap the section beneath. Its vertical edge should then be tucked beneath the siding or cupped with counter flashing.
