1 Remove the old roof
2 Remove old underlayment
3 Inspect the plywood (better known as decking board) It will be an additional cost to replace plywood that is damaged (fee is per plywood replaced)
4 After the plywood or decking board has been replaced, we will proceed with installing drip-edge on the eaves. Next on top of the drip-edge the ice water shield is installed. This will ensure double protection on our roof in times of a lot of rain and snow.
5 The fifth step is to install the new paper felt also known as underlayment
6- The sixth step is to install the drip-edge on the rakes, remember that in step 4 we install drip-edge only on the eaves. In this occasion the underlayment is installed first and then the drip-edge for better securing of the roof.
7 This step is very important because the whole ceiling is measured and marked with red or blue lines for an excellent job. It also helps the new shingles to be installed in straight lines for better presentation and also as indicated in the GAF manufactures manual
8 In this step the new shingles are ready to be installed. Depending on the type of shingles that are installed, will also depend on how many nails will be used. For example an Architectural shingle 6 nails will be used per each shingle and must be distributed evenly on each shingle. If we are using three tap shingles, then 4 nails per shingle will be used (It is not recommended to use more because it can cause leakage).
9 Once we have installed the new roof, it is cleaned with a blower.
10 Finally we go through all areas with a magnet to collect the nails that have fallen on the ground. For around the house we use a very strong magnet that can pick up nails wherever they have fallen.
