Drone Video Footage of a Commercial Flat Roofing Project Installing Fully Adhered EPDM Membrane.
This particular flat roof is 4.5 football fields in size. It is a tar and gravel flat roof on an industrial / commercial building that has a failed roof system. We are installing a fully adhered 60 mil EPDM flat roof system on the building.
In colder areas of Canada an EPDM or SBS Modified Torch-On flat roof system are preferred. In warmer areas such as Vancouver, downtown Toronto, or in warm areas of the USA reflective systems such as TPO, PVC or reflective roof coatings should be considered.
The advantage of using EPDM (especially fully adhered) in colder areas like Alberta, Saskatchewan, Manitoba, some parts of BC and Ontario is that EPDM expands and contracts very well with the change in temperatures. 2 Ply SBS Modified Bitumen Torch-On flat roofing is stronger for foot traffic (if your roof is going to have a lot of foot traffic) but it is not near as flexible as EPDM.
We recommend fully adhered EPDM over mechanically fastened EPDM membranes and loose-laid EPDM membrane roof assemblies. Loose-laid EPDM is much cheaper because the install time is shorter than with fully adhered (and the glue is expensive with fully adhered) but the disadvantage a loose-laid EPDM ballast system is maintenance costs in future. If you have to move the rock ballast to locate leaks in the future then this can be very costly.
