Be prepared to make sure the nails are firmly lodged in the felt and sheathing while installing shingles. The heat from the sun causes the roof and shingles to expand with time, causing the nails to pop out of position and increasing the danger of a leak. If you’re not an expert in this, getting a roofing repair Gettysburg-located, or any location is the best option. Below is how to fix your shingles in three easy steps:
Step 1: Repairing Sheathing
Lay down a foundation after removing the dirt and re-framing the roof (sheathing). The sheathing is typically made of eight-foot-long, 1/2-inch-thick plywood. Measure the aperture of the shingled roof portion, cut the plywood to size, then attach the plywood to the roof rafters.
For added strength, stagger the sheathing in a brick pattern. Avoid putting a full 8-foot length of plywood on the roof. The midsection of such a lengthy composition is structurally unsound. Continue to place the plywood seams in a brick pattern until the open space is covered.
Step 2: Spread the Felt Paper
Begin by stapling the 6-inch beginning strip at the bottom of the roof, allowing a 1-inch overhang on the eave to allow for drainage into the gutters. Lay and nail the remaining felt layers with a 2-inch overlap from the bottom up. To guarantee optimum retention, nail the tar strip to each felt layer.
Step 3: Install the Shingles
Start laying the first row of shingles at the roof’s bottom corner. Start with a base row of shingles and work your way up in a pyramid form, following the chalk lines on the felt. To achieve optimal grip, use six nails per shingle and always nail on the tar strip.
Following your first pyramid foundation, continue working your way across and up the roof. If you’re replacing shingles on an area of your roof that’s been damaged, make sure you put the old ones on top of the new ones. This will give a consistent and seamless appearance.
