Interestingly, Rio Blanco Roofing & Restoration used hot asphalt and felt paper with a gravel ballast for flat roofing in the past but has since stopped using this type of roofing because there are now much better and more cost effective options for your San Antonio low slope roofing needs. We currently use several different roofing materials to engineer our flat roofs, including modified bitumen, polyvinyl chloride and thermoplastic polyolefin.
Furthermore, we have shifted to perpetual membrane sheeting for many of our flat roofs installations. Rio Blanco Roofing & Restoration has found that perpetual membranes are more resistant to accumulated static water during the rainier seasons. In addition, we use top-grade adhesives to bond together multiple sheets in order to offset the penetration of wind and water with many of our flat roofing structures.
For smaller, residential, flat roofs, like patio covers and small additions, we often recommend and install a granule covered modified bitumen roofing that can be color matched to the asphalt shingle selection used on the sloped roof areas of the house. This can be installed in a one, two or three ply system. For the flat roofs above living space we recommend a three ply system. Rio Blanco Roofing can install insulation board or sheeting on the flat roof prior to installing the final modified bitumen roofing in the event that the customer would like to increase the thermal quality of the roof to cut down on utility costs.
