Now that you have the roof properly dried-in and flashed with approved materials, Begin the roof installation by applying the starter course. F Wave REVIA Starter is universal for all profiles. Do not use the starter on rake edges. Cut 6 ½” off of the first piece of starter before installing to offset the seam from that of the shingles that will cover it.
If using D-Style drip edge, simply align the starters bottom edge flush with the edge of the flashing. If using plain drip edge, then overhang the starter ¼ - 3/4”.
F Wave requires the use of 11- or 12-gauge roofing nails that are corrosion-resistant and with heads that are a minimum of 3/8” in diameter and a minimum of 1 ¼” long for field shingles, 1 3/4” for Hip & Ridge. All fasteners should penetrate ¾” into the roof deck. Ring shank nails are recommended to improve wind resistance.
6 nails per shingle are required on both field and starter shingles. Place fasteners only in areas that will not show in shingle keyways. Install the fasteners 1 ½” – 3” above the eave edge to ensure the fasteners enters solid decking.
You will need to increase your guns pressure vs asphalt, as F Wave is a thicker and stronger material. Be sure to hand finish any under-driven nails, as they can cause sealing and cosmetic issues with the next course.
For Designer Slate profiles, Field Shingles must be installed with 1 ½ tab offsets in a diagonal application pattern. Use the alignment marks on each shingle to ensure a consistent offset between courses. Do not cheat the exposure or offset on any shingle as this will disrupt the alignment of any subsequent courses.
For Revia Hand-Split Shake installations, shingles should be placed randomly within the marked area for the most realistic look possible. Or use the “1-2-3” markings by laying a course at marking 1, the next course at marking 2, and the next course at marking 3. Simply repeat this process moving up the roof.
