OK so after the roof section has been framed, It is covered with an exterior grade decking, or a sheathing as it is called in the industry. Now this sheathing is normally a plywood product. either plywood or plywood particle board. Also a product called OSB which is a particle board. These materials, sheathing or plywood decking are nailed to the rafters. This is what will be supporting the final roofing and shingles.
This decking or sheathing should be applied perpendicular to the rafters. Each end of roof decking or plywood, must rest on half of a rafter. In other words each sheet of plywood or decking should share a rafter. Also they should be staggered so that no two seams are together. To stagger the seams, On one end of the row you will have to cut the plywood in half. Then on the next row the other end piece should be cut in half. This ensures and maintains the stagger.
The sheathing or decking is then covered with an underlayment. This underlayment is also called roofing paper or tar paper, an asphalt saturated felt paper. Flashing is a sheet metal product, used to help keep water from blowing under the roofing materials. Flashing is placed at the eaves and around any type of possible openings in the roof. Also flashing is used where the roof meets a vertical wall.
Shingles of different types and qualities are available. Also there are grades and different warranties. Shingles can only be used for sloping roofs. Shingles are sold by the square. A square will cover 100 square foot of roof. the recommended underlayment for shingles is #15 asphalt saturated felt. Alright once your roof has its underlayment, flashing, and drip edge all in place, then the shingles can be applied. Basically, the way which is the easiest, and requires the least amount of cutting work, is to……
- Start a row at the bottom with the tabs pointing up towards high center.
- Next step is to lay another row on top of that row with tabs facing down. start this step with a full shingle
- start this step half way up the other shingles.When starting this row cut half of a tab off so as to stagger the shingles
- Start the next row half way up on top of the last row, this time start the row with a full shingle.
- Do this staggering, back and forth, all the way up
- Do the same steps for the other side.
- There are several ways to make a ridge cap. I recommend buying a good ridge cap and installing as directed. It’s easy, fast, and has a guarantee.
I have basically laid it out and explained the process as best as possible. These are basic steps to securing a satisfactory roofing job. Roofing is not difficult, however it can be hard, hot, work.
