Roofing materials for flat roofs vary depending on the type of flat roof system used on your commercial roof. For single ply roofs, rubber rolls or paint is the roofing base. Built up roofs use a mixture of gravel and tar to create a thick layer strong enough to walk on. Modified bitumen is like rubber roofing, but made of smelly polymer. Cool roofs can be a multitude of many flat roofing options, from metal to rubber to green vegetative roofs- as long as they reflect sunlight and are environmentally friendly, they are considered a cool roof. A flat metal roof is made of metal, and the benefits and costs vary depending on what type of metal is used.

  • BUR: Layers of gravel, felt, and tar are stacked together to create fireproof and walkable roofs.
  • Cool: Energy efficient roofing that helps reflect sunlight and cool buildings.
  • Modified Bitumen: Polymer and asphalt that are torched down to the roof to create a strong coated roof.
  • Single Ply: Thin rubber-based rolls that are melted together to create a flat seamless surface.
  • Metal: Versatile for both sloped and flat roofs, metal is welded together for a waterproof seamless finish.

Which Flat Roof Is Right For You?

A rubber flat roof or a BUR roof are the most common flat roof installation picks for commercial building owners. Both are very cost effective, but single ply rubber roofing systems are much lighter than BUR roofing. All roofing will offer some amount of energy efficiency, but if that is your primary goal, going with a cool roofing option that supplies a lot of reflectivity like metal or EPDM is a better choice.

Modified Bitumen Flat Roof

Modified Bitumen Membrane

If you are looking for something thicker than the one layer of a single ply roof, but not as thick a the multiple stacks of tar and felt fiberglass asphalt used to make built up roofs, then a modified bitumen roof system is the perfect choice for something in between. Also known as two-ply roofing, modified bitumen roofing is a combination of single ply and built up roofs. By that, we mean that materials found in BURs like asphalt are melted down with rubber modifiers to make it elastic and durable, which is what single ply membrane roofs are famous for. The result is a six layer semi-thick coated roof. To get modified bitumen roofing in Fate and Rockwall, TX, call Advanced Roofing Systems at (214) 247-7002 today.

Modified Bitumen Roof Installation

The six layers consist of insulation, base sheets, a polyester or fiberglass membrane, adhesive, a surface coat to protect against UV rays and weathering, and flashing which protects areas of the roof where leaks are common like gaps near the edge, any perforations, or around vents. This thin yet multi layered roof is then strong enough to last for 20 years before needing to be restored. And a huge benefits of modified bitumen roofs are that they don’t have to be replaced; just apply a restorative roof coating on top of them for another 20 years of use!

Built Up Flat Roof

What is a Built Up Roof?

The original flat roofing system, built up roofs have been around since the 1800s. While no longer the most popular option now that other choices are available, they haven’t completely fallen off the map as people still appreciate their great benefits. Lasting the average 12 years before needing a replacement or repairs, built up roofs are a good selection for commercial building owners who want a flat roof that supplies great benefits while also adding an aesthetic touch. For installation or repair of your Fate and Rockwall, TX built up roof, call the roofers at Advanced Roofing Systems at (214) 247-7002 today.

Pros and Cons of a Built up Roofing System

Built up roofs, also known as BUR, or tar and gravel roofs are made of several layers of fiberglass asphalt shingles alternated with tar adhesive to create a thick and heavy roof that protects the the building from sun, water, and other damage. While fire and chemical retardant and able to handle heavy traffic, BURs are a smelly, messy, and and time consuming installation process.
