Built Up Roofing
Built-Up Roofing is one of the oldest and most reliable methods of roofing. It was first known as composition roofing and started in the 1840’s. Built Up roofs are exactly that, they consist of several (as many as 6) plies of roof felt laminated in hot asphalt and surfaced with gravel set in a flood coat of asphalt.
Many different types of materials with different qualities are available. This variety of material allows the quality of the roof to be tailored to the specific requirements of the structure. Built up roofs can be installed on virtually any type of roof deck. Some of the benefits of a Built Up roof are:
- The multiple plies create terrific protection against leaks.
- The flood coat and gravel surfacing provide impact resistance and UV protection.
- Extreme resistance to wind uplift.
