Tile - We use a 2 layers of 30# ASTM felt, 40# ASTM felt or TG-2 underlayment. New wood battens are then installed as well as new roof penetrations (T-tops, pipe jacks, etc.). Tile will then be installed.
Shingles - We use a 15# ASTM felt underlayment. Shingles are made of fiberglass and you can choose 20 year or 25 year 3 Tab Shingles or 30 year Dimensional shingles. Shingles come in many colors and are made by several manufacturers.
Flat Roof Coating - We re-coat roofs that have previously been coated and we also coat over existing foam roofs. We use a roller to roll on the coating where other companies will just spray it on. Rolling gives better coverage.
