There are several key items that must be focused on to ensure that a shingle installation on a steep slope roof is done correctly.
The roof valley is subject to the most water during a storm and therefore must be properly installed. In open valleys, a piece of metal is used to help keep rainwater flowing of the roof. Shingles are used in a closed valley and proper installation keeps the water flowing for proper drainage.
Another key item in shingle installation is the use of starter shingles. Starter shingles ensure that the first row of shingles seal down properly and protect the roof edge. They also provide for high anchoring power.
A proper installation must also consider the underlayment. The underlayment serves as a second barrier and protects the roof from water damage. It is important the underlayment does not wrinkle during installation.
The shingles must be installed according to the manufacturers recommendation. Nails must be placed where the manufacturer recommends and in the quantity recommended.
