Definitions and Options
Built Up – The term “built-up” roofing refers the process of applying multiple layers of felts in hot asphalt and building the roof from the deck up. Built-up roofs can be adapted to a variety of applications. They can be surfaced with gravel, cap sheet, and cool roof rated cap sheet.
Modified – Modified roofing refers to asphalt-based materials that have been reinforced or strengthened during the manufacturing process through the addition of different materials. Modified roof felts tend to have stronger physical properties than traditional felts. They have greater flexibility and puncture resistance. Modified roofing products can be mopped with hot asphalt, heat welded with an open flame, or set in cold process adhesive, depending on the needs and limitations of the particular project.
Single Ply – Single-ply roofing comes in three different base materials: EPDM, TPO, and PVC. EPDM materials have a long track record of performance. TPO is currently the most common roofing material installed in the United States. PVC roofing materials have been in use for the longest time, and have had a very successful performance record.
Coatings – There are many products available that can be fluid-applied over an existing roof system to extend its lifespan. Some of these products can provide benefits equal to that of an entirely new roof system.
Tile – The use of tiles on roofs is one of the oldest practices in construction; tried and true, tile has been used as a roofing material for literally thousands of years. There is a large variety of tile roofing materials available, including traditional clay mission-style tile, interlocking concrete tile, or decorative ornamental tile.
Shingle – There are many different types of roofing shingles on the market today providing a variety of aesthetic options without compromising performance. These options include wood shingles and shakes, asphalt composition shingles, synthetic composition shingles, and designer shingles, which can provide many different stylized surfaces.
Slate – Slate roofing is one of the most dependable options in steep roofing, and has a unique aesthetic quality. The physical properties of a slate roof make it one of the most long-lasting products on the market.
