Smooth Surface 15lb Black Felt Paper Easy Installation With No Smell

15 Felt Roof Underlayment Paper Saturated Asphalt Roofing Felt Roll Membrane

Introduction:

Asphalt Saturated Organic Felts are manufactured from premium quality organic mat and saturated with high-grade asphalt.

Asphalt Saturated Organic Felts are designed as an underlayment product to be applied over the roof deck prior to the installation of asphalt shingles. Install Asphalt Saturated Organic Felts as a secondary barrier to moisture caused by wind-driven rain and ice damming.

Application:

1.Organic Felt rolls must be installed horizontally, from the bottom of the roof deck.

2.Anchor the top corner of the Felt roll after it has been properly positioned in place; then spread the roll across the roof. Care must be taken to roll out the Felt smoothly and to avoid any wrinkles as the Felt is unrolled across the roof.

3.At slopes 4:12 and greater, a single layer of Felt rolls shall be installed parallel to and starting at the eaves, over lapped at least two inches, and fastened sufficiently to hold in place.

4.Continue to install the next course of Felt from the roof edge and overlap with the previous course as described above, according to the roof slope. If a new roll is required to complete the installation to the end of the roof, overlap the new roll over the prior roll by at least four inches. Use the same fastening pattern for the top, the middle and the bottom of the roll for all subsequent courses.

5. Continue this pattern until the top of the roof. Fasten the top course if it terminates at the top edge of the roof. Otherwise, overlap the Felt over the ridge and fasten it. Repeat the process from the bottom of the other side of roof deck as described above, depending on the slope of the roof.

6.Fasten the Felt in the valleys using the same pattern, taking care to avoid wrinkles. If wrinkles are formed while fastening the Felt, slice the wrinkles and fasten them flat to the deck. Then seal the cuts with waterproofing cement.

General Precautions

1.Asphalt Saturated Organic Felt rolls shall not be installed when wet.

2. Do not walk on the Felt before fastening it into proper position on the roof deck.

3.Local codes may supersede these instructions. Check with the local building code administrator for specific requirements.

Storage and Handling

We recommend that the rolls be kept in a dry area out of the weather. If you are applying the felt in cold weather, we recommend storing it in a warm place at least 24 hours before applying to roof.

Application/Use:

Organic felt is an underlayment and moisture barrier between the primary roof (for example asphalt shingles) and the roof decking. It is not intended to be a primary roof. We recommend that the primary roof be installed immediately after the application of the felt.
