# 15 ASTM Saturated Felt Paper Asphalt Roofing Felt Roll Roofing Underlayment

 

Introduction:

 

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.

Characteristic:

 

  • Features

  • Required underlayment for roofs and some wood siding
  •  
  • Most economical roofing underlayment
  •  
  • Heavy duty design lays flat to minimize wrinkling
  •  
  • Accurate lay lines allow for easier, consistent shingle application
  •  
  • Slip resistant for safety in warmer climates

 

  • Manufacturer may vary

Installation:

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

2. The first layer of Felt rolls must be installed to cover the entire bottom edge of the roof deck to facilitate the water shedding ability of the Felt.

3. 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

4. Install fasteners at least eight inches at the top and middle edges and at the eave along the deck.

5. At slopes between 2:12 and 4:12 pitch, install a double layer of Felt as follows. Apply a minimum 19 inch wide strip of Felt parallel to and starting at the eaves, fastened sufficiently to hold in place. Starting at the eave, apply a full width Felt roll, overlapping successive sheets 19 inches, fastened sufficiently to hold in place.

6. The second course of Felt should be aligned with the roof edge and overlap the first course as described above, according to the roofing slope. Fasten the Felt to the deck and repeat the pattern.

7.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.

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

4.Install the primary roof covering immediately after installation of the Felt.

Storage:

1.Asphalt Saturated Organic Felt rolls require protection from damage and the weather.

2. Constantly store rolls upright, in a dry location.

3. When storing two pallets high, position a plywood sheet between pallets.
