Built-up torch down roofs
Torch down roofing (or modified bitumen) is widely used for roofing on flat roofs. Its name is derived from the method of torching the bitumen sheets onto a fiberglass base during installation. The material used in the torch down process is also know as rubberized asphalt. Melting of the bitumen by torching creates a strong and consistent seal which makes torch down roofs long- lasting. Although it is slightly more expensive, the roofing torch down method is generally regarded as preferable to the alternative method of roofing used for flat roof involving the use of tar and gravel. There are no noxious fumes associated with torch down roofing installation, and torch down roofs are regarded as more durable and resistant. The high quality resins that are combined with the modified bitumen in torch down roofing installation also help to provide protection from UV rays that could otherwise provide damaging.

STEEP SLOPE ROOFING SYSTEMS
Asphalt Shingles possess an overwhelming share of the U.S. steep-slope roofing market. Asphalt shingles are reinforced with fiberglass materials.
Fiberglass shingles consist of a fiberglass mat, top-and-bottom layers of asphalt, and mineral granules. Asphalt shingles fire resistances, like most other roofing materials, are categorized by Class A, B or C. Class A signifies the most fire-resistant; Classes B and C denote less fire resistance. Generally, most fiberglass shingles have Class A fire ratings, and most organic shingles have Class C ratings. A shingle’s reinforcement has little effect on its appearance. Fiberglass products are available in laminated (architectural) grades that offer a textured appearance. Zinc or copper-coated ceramic granules also can be applied to fiberglass products to protect against algae attack, a common problem in South Florida. Asphalt shingles also are available in a variety of colors.
Regardless of their reinforcing type and appearance, asphalt shingles’ physical characteristics vary significantly. When installing asphalt shingles, NRCA recommends use of shingles that comply with American Society for Testing and Materials (ASTM) standards. ASTM D 3462 for fiberglass shingles. These standards govern the composition and physical properties of asphalt shingles; not all asphalt shingles on the market comply with these standards. If a shingle product complies with one of these standards, it is typically noted in the manufacturer’s product literature and on the package wrapper.
TILE ROOFING Systems
Clay or concrete tile is a durable roofing material. Mission and Spanish-style round-topped tiles are used widely in South Florida, and flat styles also are available to create French and English looks. Tile is available in a variety of colors and finishes. Tile is heavy. If you are replacing another type of roof system with tile, you will need to verify that the structure can support the load.
