Flat Roofing Dallas, TX

Serving the Dallas-Fort Worth Metroplex

A flat roofing system is described as a roof that is almost completely level. However, no roof can be completely level as it wouldn’t allow rainwater to drain off causing all kinds of problems. Most flat roofs have a slight pitch of at least 1.19 degrees. Flat roofs are very common in commercial buildings and are common for residential buildings in warm climates or home extensions like garages and outbuildings. A flat roof is generally more cost-effective in warm climates than pitched roof buildings because it helps the inside temperature of the building to remain stable.

Built-Up Roofing (BUR)

Built up roof membranes, or BUR, are very common in industrial buildings. They are also commonly known as ¨tar and gravel¨ roofs. The surface of the roof is covered in layers of bitumen and reinforcing fabrics to create the finished weather proof membrane. The number of plies, or layers, can differ. These fabrics can be applied directly to the roof deck or the insulation. The most common bitumen used is asphalt, coal tar, or cold-applied adhesive. Once the fabrics and bitumen are applied, surfacing is laid in over the top. Possible surfacings include gravel, slag, or mineral granules, glass fiber cap sheets, hot asphalt, aluminum coatings, or elastomeric coatings.

Z

Complete seal: there are no seams that need to be heat-welded or glued down

Z

Lifespan: you can expect 5 years per layer, meaning you can easily get 20-years out of your BUR system

Z

Resistant to UV: the natural rock covering acts as the perfect barrier to protect the roof’s underlayers from destructive UV radiation

Z

Low maintenance: BUR require little to no maintenance throughout its life span

Z

Fire resistance: Falling ashes or sparks will not find purchase on your roof preventing it from catching fire

Modified Bitumen Roofing (MBR)

Modified Bitumen roofing systems, or MBR roofing, is similar to standard BUR other than that modifiers are added to the asphalt and the bitumen is reinforced with fiberglass or polyester fiber matting to make the roof stronger and more durable. The two most common types of MBR are SBS (styrene-butadiene-syrene) and APP (attactic polypropylene). SBS is used to increase the flexibility of the roof membrane and gives it better expansion and contraction abilities. While APP is used to increase the lifespan and ageability of the membrane. Common installation methods are the torch method, heated asphalts, or cold adhesives.

Z

Self-adhering: modified bitumen technology has advanced so that there is little to no risk of heat-related accidents during installation

Z

Low VOC components: the materials used have low harmful toxins making installation and use of the space safer

Z

Reduced energy bills: MBR is light in color and reflects heat, meaning it won’t absorb or retain heat keeping the internal temperature stable regardless of the weather

Z

Recyclable: MBR materials are recyclable, when it comes time to redo the roof, your old materials can be reused on other future projects

Z

Cold weather performance: MBR has great performance in hot and cold weather, the materials will remain flexible and resist cracking and leaking even in freezing temperatures

Membrane (Single-ply) Roofing

Membrane single-ply roofing can utilize a variety of different materials, but their main characteristic is that they are designed to be installed in one single layer. Their most defining qualities are that they are extremely flexible and resistant to UV radiation. The single-ply is usually installed in a black or white finish and then applied directly over the roof’s insulation material. Single-ply membranes generally come in two types: Thermosets and Thermoplastics. Thermosets are made from synthetic rubber polymers while Thermoplastics are plastics based. Both types are quick and easy to install, but cannot be used in conjunction with other roofing systems.

Z

Impervious to dramatic changes in weather: remains flexible and crack-resistant regardless of dramatic temperature changes

Z

Resistant to chemical damage: chemical storage or spillage will not affect this roofing type

Z

Customizable grade: you can choose the desired grade of protection you want for your roof depending on your particular climate and needs

Z

Increased energy savings: this roofing type has excellent reflective properties allowing the internal temperature of the building to remain constant

Z

Low cost: because it is so easy to install, labor costs are lower than other more labor-intensive roofing options
