- On this Residential Re-Roof we tore off the old shingles that were previously installed on the roof. We then checked all the decking to make sure that it was in good condition. Once that was completed it was time to dry-in the home with Underlayment and Ice & Water. We then installed the metal and started installation of the shingles, vents, and ridge. On this specific project the customer chose Malarkey Highlander Shingles in Sienna Blend.
