Roof Underlayment Graphic

A good roof underlayment is responsible for determining if a roof is really in good shape.

Under your roof’s shingles, is another barrier against rain, ice, and water leaks. This barrier is often the last layer of protection between the outside elements and your roof.

What underlayment essentially does is act like a weather shield, preventing leaks that result from water damming in the gutters, ice dams, wind driven rain, and any vulnerable areas of your roof like around skylights, chimneys, vent pipes, and at the eaves.

You have probably seen some form of underlayment known as traditional felt paper, or tar paper. This is a rolled material that is saturated in asphalt and nailed down under the shingles of a roof. Felt underlayment also comes in a synthetic version, made of polypropylene, fiberglass, polyethylene, or polyester. These synthetic versions are lighter, more effective, and more resistant to wind blow offs and wind driven rain. Further, it lasts longer than traditional asphalt, and tends to be easier to install.

In summary

Whatever version you choose, the purpose is the same: to keep water out of your roof. Nevertheless, you need the eye of a qualified roofing contractor to know if water is already collecting under you roof. The statement, “If you don’t know, it is best to check,” applies here. Working with a good roofing contractor can not only save you from costly repairs later, but keep your roof in the best condition possible, extending its’ life and saving you money down the road.
