Build Up Roofing Systems
Build Up Roofing Services in Houston and the Texas Gulf Coast “Standing the test of time for over 35 years”
Built–Up Roofing (BUR) is one of the oldest low–slope roof systems still used on both residential and commercial roofs today. BUR’s century–old track record is unsurpassed in the roofing industry and continues to afford dependable service to homeowners and building owners alike.
How Long Do They Last?
The service life of a roof is dependent on many factors: geographical location & weather conditions, foot traffic, materials used, conditions under which the roof was installed, slope of roof, type of surfacing material, etc. Under ideal conditions, a 3-ply built-up roof should last at least fifteen years, a 4-ply should last at least 20 years, and a 5-ply should last at least 25 years. This author has seen ten year old 4-ply roof that needed to be replaced and twenty year old 3-ply roofs that were still functioning.
Benefits of Built–Up Roofing
- Provides excellent resistance against foot traffic on roof and common rooftop abuse when needed.
- Versatile application options – Different surfacing choices allow better solutions for even the most challenging situations.
- Affordable alternative when needed to more “high tech” systems.
- Extremely durable, especially when the rooftop is being used to accommodate extensive mechanical equipment.
How It’s Made
BUR systems are made of asphalt and fiberglass felts. These are assembled on the rooftop. The asphalt is heated to its equiviscous temperature (450 – 550°F), which is pumped to the roof where the felts are installed in a “layering” pattern.
Asphalt is the adhesive and waterproofing element of a built–up roof system. We are essentially “building” a roof. After the felts have been installed there are several different ways of “surfacing” to complete the system. Granular surfaced cap sheet, gravel aggregates, or reflective coatings are used to protect the membranes and also help protect the roof from UV deterioration.
Add an Energy Star® Coating to a Built Up Roof
Adding a reflective coating to a built up roof creates a cool roof system. Quality coatings installed properly on a built up roof reduces the surface temperature by 60-100 degrees in the summer, thereby reducing your energy costs and contributing to reduced urban heat-island effect and pollutants. It serves as a sacrificial layer to the elements and reduces thermal shock roof damage to the building by moderating natural expansion and contraction which occurs when cool rain hits a hot roof.
Along with twice-annual preventive roof cleaning and maintenance, a new coating layer can simply be installed every 10-12 years – avoiding the need for future costly tear-off and replacement and reducing landfill environmental impact (did you know that U.S. landfills are comprised 7-10% of roofing waste?).
