How ‘Built up Roofing’ Systems works
Built Up Roofing or also known as, BUR, have been utilized for commercial roofing purposes for over 100 years! It is called a “Built-Up” or Membrane roofing as there are alternating layers of material used to create a sealed and insulated membrane. Odds are you have seen a BUR in the past! They are finished with a layer of gravel and can also be referred to as Tar and Gravel roof.
Layers of a ‘Built-Up-Roofing’
- Deck Surface- otherwise known as an unfished Roof
- Insulation Deck- This material is secure in place to be able to handle the material to be placed atop it. This provides some separation from the physical roof and disrupts weight evenly.
- Insulation- Depending on your buildings need the type of insulation used may vary
- Roofing/Membrane Asphalt- Layers of rubber roofing membrane are bonded together with roofing asphalt. The number of layers can vary but an industry standard tends to be 4 layers of
- Gravel- An additional layer of asphalt is laid down followed by gravel that is dispersed evenly. Gravel is used to keep direct sun off the asphalt in addition to it providing some additional insulation and heat dispersion.
- *Aluminon Finish- Some opt to finish the top of their BUR with an additional layer aluminum as oppose to gravel.
What to expect with your Built-Up Roof?
Like any roofing solution, “Built Up Roofs” or Bitumen Roofs are designed to insulate and securely keep water out of the building. Due to the strength and resilience of the layers utilized in BUR roofing, this is a great commercial option. With its insulation properties keeping cool air in during the summer and warm air inside during the winter months, a Built-Up-Roof from REI can help lower your heating costs. In addition to saving money, your company will decrease their carbon footprint!

If properly installed and maintained, Built-Up-Roofing solutions can last up to 30 years. Checking the roof twice a year and checking for vulnerabilities is recommended.
