Install the ridge cap so the prevailing winds blow over the overlap seams, not into them. Once all your shingles are put in, you’ll have to cover the ridge . The high ridge cap shingles will overlap the hip ridge cap, so start with the hips.
Line up the bottom of the primary row of shingles with the underside fringe of the starter row, making sure the seams are staggered. With that row complete, you’ll want to figure out the reveal (the portion of the shingle that isn’t lined by the one above it). Standard reveals differ between 5 and 6-half of in. Whatever the reveal is meant to be, snap a horizontal line that distance from the highest of the primary row of shingles . Cut the flashing back to the peak along each crease.
Invest in a number of massive tarps to protect your plants and landscaping and to catch the thousands of nails that will rain down off the roof. It could be downright inconceivable to remove old self-stick ice-and-water underlayment, nevertheless it’s OK if you need to go away it in place. And if at all attainable, have the rented trash bin parked close to the house so you can toss within the old shingles proper from the roof.
Run the underlayment past the drip edge on the eaves, and trim off the extra with a utility knife. Once it is smooth, nail it down on the skin edges.
Cover the remainder of the roof with No. 15 asphalt-saturated felt underlayment (some codes might require No. 30). Each layer overlaps the lower one by a minimum of 2 in. Follow this step by nailing drip edge alongside rakes , on high of the underlayment. As you probably did with the flashing, at all times lap higher items over decrease pieces. The felt keeps the roof deck dry earlier than shingles go on, protects towards wind-driven rain as shingles fail and increases hearth resistance. To set up corrugated roofing, start by slicing your panels to length with an angle grinder.
Then fold the flashing over the peak and canopy the cut ends with self-stick underlayment.Roof valleys channel plenty of water, so that they want further protection. Start by putting in self-stick underlayment on the decking. This course of is much easier with two folks. Cut the underlayment to measurement , and peel off the complete plastic backer. With a person on every end, fold the underlayment in on itself, sticky facet out. Try to push it down into the crease of the valley as tightly as possible. If this self-stick ice-and- water underlayment bridges either side of the decking, leaving a niche underneath, it may tear once you put in the metallic valley flashing.
Finally, nail the primary course of shingles instantly on prime of and flush with the starter course. Use four roofing nails per shingle, as indicated on package instructions (six nails in high-wind areas). Once this course is laid, you’ll be able to start snapping horizontal chalk strains up the roof to ensure straight rows. of the shingle tabs the place the bottom fringe of the tab meets the highest of the cutout. Snap chalk traces to help maintain the row of ridge cap shingles straight.
Snap a few information traces just a little contained in the perimeter of the ridge so the strains get covered up if you’re done. Nail each shingle on either side about 1 in. Store-purchased architectural-type ridge caps are often two layers thick, to match the look of the shingles. You may need longer nails to fasten the ridge because of all the extra layers of shingles. They match into any normal utility knife identical to straight blades. Laying shingles is not straightforward, but it’s most likely the best a part of roofing a house.
