How to Cap a Hip Roof How to Cap a Hip Roof
A hip roof is a typical residential roof with slanting and diagonally slanting edges. Two types of shingles are used on these roofs: tabbed and square. The square ones are to cap the roof or hip. Installing them correctly is your best defense against bad weather and a leaky roof.
Step 1 - Marking Your Path
Taking one of the shingles lay it across the hip where it aligns over the other side of the hip. Using another shingle do the same thing overlapping where the first one is to make a joining as it should look nailed on. Mark the ends on either side of the roof where the shingles stop. This is where you will snap your chalk line to use as a marker all the way across.
Step 2- Laying the Shingles
Using a two-pack of shingles, lay starter on the edge of the hip roof letting the edges fall over the edge. Nail on both sides of the roof as close to the edge of the shingle as possible. Using the utility knife, cut the excess off the edges that extending over the roof. Don't leave any roofing exposed when you make the cut. Make sure it is just at the edge where no wind can get underneath it.
Step 3 - Overlapping the Shingles
Using another cap shingle lay it across the starter shingle by half, covering the nails you have used to secure the first shingle. Nail this one the same way one nail on each side of the roof. Continue this step until you reach the end of the hip.
Step 4 - Edging the Hip
Once you have gone all the way across the hip roof line with the cap shingles you need to edge the end of the hip. You need to take the last shingle with only the decorative part showing, and nail it on both sides of the roof. Now cover the exposed nails with roofing cement to prevent any leaks. Use the utility knife to cut off the extra shingle even with the edge of the roof. Do the same with all the hips you are capping. repeating Steps 1 through 4.
Step 5 - Finishing Up
Once you have gone through all the shingles and have completed your roof, it is important to go back over and inspect the job making sure there are no exposed nail heads. There should not be any showing, if so, cover them completely with roofing cement. Any exposed nail head will lead to a leak in the roof. Make sure all the shingles have been made secure. A strong wind getting underneath them will eventually pull them off making it possible for another leak in the roof. You want your roof to last as long as possible.
