Once the garage roof felt has been cut to size start once again in the centre and follow the manufacturer s instructions on how to felt a flat shed roof with the adhesive. Once measured and cut line the first piece of felt up so that it over hangs the edge of the roof on three sides by enough to cover the side pieces of the roof. Roll the new felt out on the roof and allow it to stay on the roof for about 30 minutes. You can either measure the roof from the ground or by standing on a ladder and actually going.

When you are felting a sloped roof you start at the bottom and work your way up so that rain pours over the top of the laps and not under them. If you already have felt on the roof remove it along with any excess nails. Verges can then be created by using a ridge piece or alternatively nailing the final corrugation over a raised barge board. Once the sheets are fixed into place you can install the ridges.
