Flat Roofing - Commercial and residential
Built Up- Tar & Single Ply Roofs
Commercial and Residential Flat Roof Construction
Commercial and Residential roof construction often utilizes a flat roofing system over a flat roof. Flat roofing is just that—a process where several roofing components are layered to construct an excellent barrier from outside elements. In Florida, protection must be particularly forgiving of high winds, and extreme summer temperatures throughout the state
Single Ply Roofs
Torch Down or Single Play roofing are modified bitumen waterproofing membranes composed of carefully selected asphalts (bitumen) having superior modifying characteristics, blended with high quality polypropylene resins. Polyester fabric waterproofing membranes yield the following performance characteristics:
- Impermeable To Water
- Low Temp Flexibility
- UV Resistance
- Excellent To Acids And Most Bases
- Puncture Resistant
- Excellent Workability
- Longevity
Built-Up roofing is sometimes referred to as "Hot Tar" roofing; they are one and the same. This roofing is comprised of several alternating layers of rolled out fiberglass based materials and molten tar. First, a layer of "Base Paper" is nailed down to the prepared surface. This layer serves as a buffer between the structure and the roofing material. It allows for some structural shifting without damaging the roofing and provides a high quality surface on which to bond the roofing.
Next an asphalt-impregnated roll of fiberglass is applied to the base layer using molten tar melts and bonds with the asphalt in the fiberglass, in effect binding them into one. This step is repeated two to five times, depending on the warranty wanted, but two or three is most common and extremely effective.
