How do I install dimensional shingles? How do I install dimensional shingles?
If you live in an area that is prone to strong wind, then you may want to install dimensional shingles, as these can resist winds up to 120 miles per hour. First, you need to buy the dimensional shingles which come in a “square.” This is enough to cover 100 square meters of roofing. Second, repair the roof structure if necessary. There is no point adding new roofing over an unstable structure or patchy felt. Third, apply starter strips to the roof, which should hang over the eaves by about 1/2 inch. Finally, start applying your dimensional shingles in a staggered manner, to prevent water leaks.
