A couple of weeks ago we published a two-part series showing how a local roofing contractor shingled a roof with architectural shingles. This Project Guide is a combination of those two articles, and it covers replacing the existing roof decking, installing underlayment and ice dam protection, laying the first row, laying shingles in the field, flashing, ridge shingles and vents, and more. This how-to is a great resource for anyone looking to shingle a roof or better understand what to expect of a roofing contractor. We want to thanks readers like Jeff Williams, Reuben, David P., Mike, Perry and R.W.H.
