Installing shingles is a job that needs to be done with the utmost care. Making sure you are ready to shingle is the first thing that needs to be addressed. Go through these details before starting to shingle a roof. Make sure you have verified the contract with the homeowner. Listing the correct shingle type, the correct color, and detailing all the finishes and tiny details that go along with the job. Make sure that the job site is safe. The ladders and/or scaffolds should be secure; the job site itself should be in a well organized manner and safe. The homeowner should also be aware of any hazardous areas. The roofing material should be properly stored at all times and fall protection is needed to be put in place.
The deck should be dry and flat before starting any shingle installation job. The under-layment's that protect the deck are to be properly installed using weather watch or storm guard leak barrier, and also using shingle-mate or deck armor roof deck protection should be laying flat and not buckle up. The drip edge has to be flush to the deck to be considered properly installed. The roof deck protection should be over the eaves and under the rake edge.
Starting to shingle is where you should start the job. The back of the roof, which should be the least visible area to work out any unusual details. Do corner your team; roofers work the fastest when reaching across their bodies. Left handed roofers are faster starting on the right; right handed roofers are faster starting on their left.
