Flat roofing is a type of roof that looks almost level compared to other sloped roofs, although it is not actually flat. It has a minimal slope of around 10 degrees to allow it to drain water. It gets its name from its continuous surface—unlike sloped roofing, it doesn’t have shingles overlapping like fish scales.
Because of its construction, a flat roof has potential to hold water and snow for much longer than steeply pitched roofs. This is why proper installation is highly recommended, as well as maintenance by qualified roofers specializing in residential, commercial or industrial roofing.
Flat roofing comes in three main types:
- Built-up roofing (BUR)
This consists of several layers: One or two insulation boards at the bottom, multiple intermediate layers of asphalt or tar alternating with layers of roofing felt, and gravel at the top. The result is a tough, seamless, and thick roof assembly with high damage resistance. It is commonly used in commercial or industrial applications due to its thickness and weight. Installation must be done by qualified roofing contractors in Mississauga, as it can be messy and generate strong odours.
- Single-ply or membrane
Suitable for residential applications, membrane roofing is made up of an insulation board topped by the membrane (sheets) of ethylene propylene diene monomer (EPDM), a synthetic rubber sheet that is often utilized for pond lining. The membrane can be glued or fastened to the layer of insulation.
Repair services for membrane flat roofs are inexpensive and simple. Leaks rarely occur as long as routine proper maintenance is performed. EPDM is effective at retaining heat and therefore lowering heating bills. Other membranes are available to help keep a home cool.
- Modified Bitumen (MBR)
The lighter alternative to BUR, modified bitumen roofing is an asphalt-based and flexible material with mineral top coating, like conventional asphalt shingles. Installing MBR does not generate as much mess, odours, and smells as BUR because it is done using the torch-down method, which heats the roofing’s backside as it is unrolled. This way, the material melts to the base layer. There are self-adhesive methods, too.
