1.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.
2.Install fasteners at least eight inches at the top and middle edges and at the eave along the deck.
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. The top of each subsequent course should be fastened intermittently to hold the edge in place until the next course is applied. Make certain to secure the fasteners at the bottom of the next course to hold the top of the previous course.
6.In valleys, lay a vertical section of the Felt in the middle, along the length of the valley prior to installing a horizontal course of the Felt. If more than one section of Felt is installed in the valley, start at the bottom and overlap the top section by at least two inches to ensure proper shedding of water.
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.
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.
