Pitched Shingle Roof Underlayment Asphalt Roofing Felt Roll 3'X144' ASTM D-4869

 

Asphalt roofing felt roll introduction:

 

Asphalt roofing felt roll is comprised of a base, made from natural materials such as wood cellulose or synthetic ones such as fiberglass or polyeser, and then coated or saturated with a protective coating such as bitumen, which replels water but still allows the product to breath.

 

 

asphalt roofing felt roll are installed under your shingles and provide your home with a second layer of protection. the primary function of the underlayment is to provide a moisture barrier. asphalt roofing felt roll also act as a temporary insurance policy, protecting your roof deck from exposure in the event of hail, wind or other storm related damages.

 

what is asphalt roofing felt roll used for?

 

Asphalt roofing felt roll is a layer of tar paper installed beneath the shingles to provide a backup waterproof membrane in case of leakage. Felt, otherwise known as underlayment. is required when asphalt shingles are installed as a first layer of roofing or when they are applied over wood shingles or a built up roof.

 

Asphalt roofing felt can also be used as protection layer in construction project, such as subway, roofing felt is widely used.

 

How to apply asphalt roofing felt rolls?

 

First of all, clean up the roof substrate.

 

 Pick up the roll with both hands. Pull, straighten, and align the felt along the eaves. Be sure that there are no wrinkles. From behind the roll, reach over and nail down the top of the strip with roofing nails spaced 6 to 8 inches apart. Nail the middle and bottom of the felt similarly.

Position the next course of felt so that there is a 2" overlap of the first course of felt. Use the lines printed on the felt as guidelines for lining up the courses. The bottom of the second course of felt should be on top of the first course so that any moisture will flow over the layers of felt.

Roll out a few feet of felt and align the edge of the felt along the rake and the first course. Remember to leave a 2" overlap. Drive about five nails in the top right-hand corner and roll out the felt about halfway (perhaps 25 feet) across the roof. Stand on the first course of felt and work with the second course of felt above you. It is not necessary to completely nail the top edge of the course. A few nails to hold the top in place will be adequate because each top row will become a bottom row once you add another course of felt.

Nail down the bottom and middle of the second course of felt with a pattern of nails every 6 to 8 inches. Remember: never walk on felt that has not been nailed down. Continue laying felt over the remainder of the deck using the same techniques. When you reach the top course, lap about 6 inches of felt over the ridge top. The longer the deck will be exposed to the weather before shingles are applied, the more important it is to lay the felt so that the deck is watertight.
