Replacing Asphalt Shingles Instructions

  • Replacing Asphalt Shingles

    Your home’s roof is the first line of defense in keeping the elements out. It is critical to replace damaged shingles to prevent further damage to your roof. Keep in mind that repairing damaged roofs will require you to stand on your roof, potentially at a great height. Roof pitches are deceiving and what appears to be a moderate slope and potentially easy to stand on might be very dangerous and it is essential that you have a good strong ladder. It’s a good idea to work on a warm day as the shingles will be easier to work with when they are more flexible.

  • Overview

    The basics steps to replacing damaged shingles on you roof are to: 1) get yourself safely on the roof, 2) remove the damaged shingle without damaging the good ones next to it, 3) Prepare the sheathing and felt for the new shingles, and finally, installing the new shingles.

  • Removing Damaged Shingle

    Your first step is to remove the damaged shingle or shingles. In order to remove the damaged shingle, you will need to loosen the first row of good shingles above the damaged one. Use a prybar or putty knife to gently pry away the adjacent shingles so that good shingles are separated from the damaged one. Once the surrounding shingles are completely separated, gently rock the damaged shingle back and forth to remove it. Continue rocking out shingles until all the damaged pieces have been removed and only good shingles are left.

  • Remove Nails

    The next step is to remove the existing nails. Lift the uppermost good shingle, and pry the nails out, being extremely careful not to damage surrounding shingles (a small block of wood under the pry bar will help you achieve this). Try to remove as many nails as possible where you removed shingles. If there are nails that cannot remove, drive them flush to the roof with a hammer. There should be roughly four nails for each shingle. Do not leave any nails raised above the sheathing.

  • Prepare for New Shingle

    Now prep the area for the new shingle by patching any holes or tears in the felt underlayment. One of the easiest ways to do this is to apply roofing cement using a caulk gun. Squeeze out some cement and spread it thinly and evenly over the damaged area with a putty knife. It is also a good idea to cover the nails that were hammered flush with the roof sheathing with the cement as well. Have some rags or paper towels available as the cement can be very messy to work with.

  • Install New Shingles

    If you are installing several new shingles, always start with the lowest shingle and work your way up. Align the first shingle with the existing shingles and attach it with galvanized roofing nails 3/4 –inch above the shingle tabs. Continue applying shingles upwards being sure that the new shingles line up properly with the existing ones. Next, gently pry up the last good existing shingle, and carefully slide the final shingles into place and nail them into the sheething. Put a small dab of roofing cement on the last shingle where the last good shingle will come into contact with the new shingle. Do not be concerned that your new shingles do not stick to each other. The shingles are manufactured with a roofing cement strip, which becomes extremely tacky with a few warm, sunny days and will ensure a tight seal against the elements.
