Metal Roofing System

Metal, primarily thought of as a low-slope roofing material, has been found to be a roofing alternative for home and building owners with steep-slope roofs. There are two types of metal roofing products: panels and shingles. Numerous metal panel shapes and configurations exist. Metal shingles typically are intended to simulate traditional roof coverings, such as wood shakes, shingles and tile. Apart from metal roofing’s longevity, metal shingles are relatively lightweight, have a greater resistance to adverse weather and can be aesthetically pleasing. Some have Class A fire ratings.

  Synthetic roofing products simulate various traditional roof coverings, such as slate and wood shingles and shakes. However, they do not necessarily have the same properties.

  Before making a buying decision, NRCA recommends that you look at full-size samples of a proposed product, as well as manufacturers’ brochures. It also is a good idea to visit a building that is roofed with a particular product.

Information About Asphalt Shingles

Asphalt shingles

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.

Choosing The Right Low Slope Roofing System

Low Slope Roofing Systems

BUR (built up roofing)

 The name says it all. The roof is built up using multiple layers normally consisting first of a 75 lb base sheet either nailed or mopped to the roof deck depending on the deck type. Second two plies of GAF Ply 4 fiberglass are hot mopped over base sheet with hot asphalt. Last but not least a mineral surface cap sheet or mineral surface modified bitumen is mopped over the fiberglass using hot asphalt. Insulation is optional, but if are installing over a concrete roof deck it is recommended to prevent blistering.

There are many different Miami-Dade County approved application methods as well as different types of material that can be used when building up a roof the one listed above is th most commonly used in Miami and Broward County for more informationBuilt-Up Torchdown 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.  
Single Ply roofing

Unlike built-up roofing, single ply roofs are just that – one layer of roofing material as a waterproofing membrane and a weathering surface. Single ply roofing membranes are much thinner and lighter than built-up roofs. Single ply roofing is used in both residential and commercial roofing.
    Single ply roofs are typically installed either in fully adhered (glued to the insulation or fiber board bellow it) or mechanically attached to the roof deck with corrosion resistant fasteners and barbed plates.Most common single ply roofing systems today are EPDM Rubber roofing and TPO roofing systems (thermoplastic polyolefin).
