Edmonton Flat Roof Drain Installation, July 2013

GRS returned to a roof recovery job performed the year prior, when we recovered a tar and gravel roof with a new EPDM system. The client was worried about water ponding and reached out to us for quotation on drain installation. The client reached out to us to address water ponding on their flat roof, recently recovered with EPDM. There is 4-5 inches of standing water atop the roof for many days after rainfall, and would like to know what options are available for drainage to prevent structural strain. We sent out one of our journeymen to inspect the site, and their recommendation was that we install two drop drains and one scupper to facilitate better drainage. One of the problems observed by the crew member is that the dimensions of the house require eight feet of slope to properly drain the roof, something obviously not present in the flat-roof system as it is. Shortly after assessment, we provided the customer a quote for drain installation (two drop drains and one scupper). The client agreed and we set out the following day to carry out the intended work. Note: When attempting roof recovery, GRS notes that the existing roof is resurfaced as-is, unless you opt for re-engineering of the existing slope (typically more common with replacement, rather than recovery jobs). Whatever water ponding that was present before the recovery will be present after!

The servicing technician installed both requested drains (one 3" flat aluminum, the other as 4" flat aluminum). The scupper drain (6" x 4") was also installed with U-Flow clamps. We needed to wait for the proper colour of downpipe to accompany the scupper, so arrangements were made with the client to return within a few days once the pipe has arrived. (Update July 21, 2013: Downpipe received and installed.) < End Report > CODE: 14014 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
