Alternative Panel layout and Seaming
The following seaming technique is acceptable for only fully adhered roofs.
Lay roof panels out with at least a 50.8mm overlap. Fully adhere roof as instructed earlier. After the roof is adhered, use a straight edge and utility knife to cut through both layers of membrane in the area where the panels are overlapped. Remove the end cuts from both panels. This procedure creates a perfect butt splice in the same manner as a wallpaper hanger would.
Using a Scrub Pad and Seam Tape Primer prime an area 10.16cms on either side of the butt splice. Centre 15.24cms Cured Cover With Tape over the butt splice and unroll while removing the backing paper. Roll the cover strip with a steel hand roller, first rolling the length of the seam and then across the seam.
