Another Great Roof Replacement in Picayune, ms. Roof was aging and was due for a replacement before this years hurricane weather. We found some bad plywood after removing 2 layers of asphalt shingles and replaced those as well before laying down new synthetic underlayment, ice and water and then finally the homeowner decided to go with a pewter gray GAF hdz shingle that matches the home really well. Awesome upgrade, and awesome people to work with.
