This video is intended for instructional purposes on how to properly install F Wave REVIA synthetic shingles. For questions contact us at fwaveroofing.com/contact.
Slope changes such as these should be treated similar to an eave, using a “D-Style”edge-metal flashing. The top flange should extend a minimum of 2 inches on the roof deck. Lay Starter shingles even with the flashing overhang, followed by field shingles as normal. The bottom flange should overlap the top course of shingles below by a minimum of 4 inches.
For this transition type, we recommend a minimum 12” metal flashing. For other transitions, including those to Low Slope membrane materials, please see The NRCA Roofing Manual for Steep Slope Roofing
