One important skill when learning how to do roofing is the use of chalk lines. First, you’ll need to measure the height of your roof, then find the center. Use a standard utility knife to snap a vertical chalk line to that height, and work left and right from there. Some types of roofs require a left to right pattern, while others require a right to left pattern. Once you’ve determined the correct length, you can start laying shingles on the roof.
When installing the shingles on the ridge, make sure that you overlap them the entire length of the ridge, and nail them one inch over the overlap seam. If you’re installing multiple layers of shingles or overlayment, you may need longer nails. You’ll need at least one foot of overlap between the shingles and the roof edge. Once the shingles are on the roof, use nails to hold them in place.
When installing shingles on the ridge of the roof, be sure to make the ridgepiece square with the peaks. To avoid overlapping shingles, make sure that the ridgepieces are positioned on the right side of the eave, with the taller ridge facing the left. Then, apply the adhesive to the underside of the shingles using rubber washers. Spread the nails in two-foot rows, and then nail them down, making sure to tack them down evenly.
Next, the roofing felt paper is laid over the ridge. Using a standard roofing nail, staple the shingles four inches apart. Then, overlap them and make sure they’re flush with the starter nail. Then, run them over the peak of the roof, then overlap the other side. Then, secure the underlayment with roofing cap nails. This step ensures that the shingles remain in place.
Ensure that ventilation is adequate and the roof has enough space for ventilation. Underlayment is the top layer of the roof. To do this, you need to overlap the shingles along the ridge. Be sure to nail each row so that it overlaps the first row. If there are several ridges, you may need to use longer nails. Then, install the shingles on the ridge. Afterwards, nail down the ridge caps.
Roofing felt paper covers the roof above the underlayment. It is stapled with 12 staples about twelve inches apart. Be sure not to use too few because the paper will fall when you walk on it. You can also use a self-sticking underlayment, but be careful to not nail the top of the roll. You’ll need to be careful not to leave any gaps in between the shingles.
