Why Choose Us
A-Advanced Service Company offers the best roofing products in the industry. There are times when you absolutely need a new roof and there are times when options such as our asphalt coatings can help extend the existing serviceability of your roof. Roof Coating is a cold process asphalt-base coating. It preserves and prolongs the life of a roof by creating a seamless, pliable, long-lasting layer of water-repellent protection over existing roof surfaces. Roof Coating can add years of service to a roof investment. When choosing a re roofing material, it is always a good idea to pick one with a proven track record. Modified bitumen roofing materials have been around since the mid-’60s, but it took until the mid-’70s for its use to dominate the industry. Now modified bitumen roofing materials are the most widely used on flat roof commercial and residential flat roof buildings.
