Edmonton Residential EPDM Roof Replacement Part Two, March 2014

This article is a continuation of work done for the same client. The report follows service calls that occurred after the initial EPDM installation.
Inspection Report:
  • Water is ponding in the center of the roof.
  • The roof is not sloping towards the drain at all making it impossible to ever drain properly.
  • Multiple pin holes from screws popping out. This is a result of the weather changes from cold to warm and weak roof decking.
  • One lap approximately 25 ft. is fish mouthing because there was no seam tape and because of water ponding.
  • These problems will continue to happen unless remedied with a proper drain.
  • The current drain is blocked by 2 skylights and the slope is entirely incorrect.
Repair Report:
  • We observed every screw on the roof and carefully checked for any pin holes or rips.
  • We immediately tried to screw it down properly. Some were pulled out and rescrewed to sink in to prevent further punctures.
  • We cleaned the surface with membrane cleaner and scratched the surface to remove any dirt. We then applied a very thin coat of hp primer until it flashed. After it flashed we applied a thin coat of ep95 splicing cement. We then applied 4 inch round patches . There were a total of 19 of these punctures.
  • A 19 ft. lap was fish mouthing so we repeated the steps described above and applied a 6 inch by 19 ft. patch.
  • After all of the patches were done we applied EPDM lap sealant around each patch.

The following emails between the client and our project manager (italicized) show the discussions which took place in order to resolve the issue:
Good morning, I have had an opportunity to review in great detail the reports from our senior Red Seal Inter-provincial Journeyman who attended to your site most recently. When tasked with the question whether he was absolutely confident (with-out a doubt) that the roof would not fail in the future, his answer to me was that he did not know. Specifically because he was not there at installation time and more specifically because he did not know why the roof fasteners would be coming up (in other words, at issue post installation is that there have been some roof fasteners making their way up and that has caused issue to the membrane). When I pressed him further, it was in his opinion that there must be a reason for the fasteners lifting and with-out knowing the condition of or what the roof deck (substrate) was specifically made up of that it was impossible for him to guarantee me it wouldn't occur in future. As such, I am requesting your approval to completely remove the roof assembly and return a new roof assembly - one that our senior Red Seal Journeyman would attend to in person (the full installation process) and this would give me confidence in returning to you an absolute statement of assurance that there will be no further issue. In other words, if you give me clearance to re-do the roof assembly I will know exactly what the substrate is and that it is suitable or we will make it suitable and that it is done in such a way that I can confidently state that beyond a doubt we expect no future issue. This of course would be of no charge to yourself and would be scheduled to occur over the next 30 or so days (the weather isn't currently appropriate or predictable and I would need to mobilize senior staff etc). It would obviously inconvenience you but I believe it is the best course considering the fact that there have been some fasteners that have moved up and have penetrated the membrane causing issue and until we get down to the decking we just simply won't know why. If you could at your earliest convenience reply with your acceptance or questions I will then immediately start the process so that we can queue this work up in a timely manner. Thank you for your patience and ongoing consideration!
Thanks for the email.
I want to make sure I understand what you are planning to do.  Do you mean that the fix is to remove the roof membrane then to reapply it once it is clear why the nails are coming up and after whatever the problem is, is fixed?  If that is what is needed to ensure a roof with no problems then, of course, I am prepared to agree.  Can you also tell me the following:
1.  How long would the process take in terms of days?
2.  Will there be a situation when we are vulnerable to leakage and, if so, how long would we be vulnerable and what steps can be taken to lessen the risk?
3.  Would you require access to the inside of the house at any time?
4.  Would we be able to talk to the Red Seal journeyman before the operation begins in order to understand exactly what will occur?
5.  Since the roof membrane has to come off, in any event, could we do what I had originally asked and have a second way for water to get off the roof?  You may recall that I had asked (not you but the foreman who came out to do this) during the pre-job inspection when we were on the roof,  to have a 'spillway' built into the south east corner of the roof so that not all of the water had to go through the one, often inadequate, drain.  This somehow got lost in translation and did not occur and I did not press it since it would have required the roof membrane to come off and a re-sloping to allow water to flow into that area as well as down the pipe.
Thanks for your professionalism throughout.  I have been impressed that you have stood behind your work and been ready to solve problems.
Hi, Yes, we would remove, assess, solve, re-specify things like alternate drainage, brief you, re-apply membrane or anything else required. 1. The process would be between 3 - 6 days depending on what we find. 2. We would only schedule the work when the forecast is clear for the days scheduled and worst scenario we do have emergency tarping procedures, but the idea is to pick the forecast correctly. 3. We would not require the inside, it may be preferable at any unforeseen juncture, but not ever required. 4. Yes, we would have our journeyman brief you in detail in advance. 5. Yes, we can ask the journeyman to spec his work for alternate drainage to which you would be involved in the decision making process based on his recommendations in advance. Any other questions please let me know. Thanks again.
Excellent.  Sounds like a plan.  Please book us in to get this work done.
Thanks again.
Roof Replacement Begins: The crew arrived and removed all of the metal from the perimeter of the roof, as well as all skylights and the chimney. The entire roof was then prepped for rubber install to be done when the material arrives.

Upon returning to the site the crew finished laying all of the rubber and installed the skylights, drain, scuppers, and chimney. The metal was also put back on around the perimeter. The work took a little longer than expected but the client was extremely satisfied with the job. She also informed us that she does not believe the leak was the fault of GRS, but rather was from an existing shingle problem area around the skylights.

Edmonton Residential Skylight Repair, March 2013

This client required a skylight repair service on his residential rooftop as there was water ponding around the skylight. A crew member was dispatched to perform the repairs. Future maintenance will be done by GRS if necessary. Inspection, March 2, 2013: The problem with this site is that water is ponding around the skylight and leaking into the home. The skylight is only 3 inches high. I have advised the client that water is getting behind the stripping around the skylight. I also advised that the curb must exceed 8 inches above roof level. The skylight is 58 inches by 90 inches.

Edmonton Flat Roof Repair and Inspection, October 2011

This report follows an inspection request from a client in Edmonton who was concerned about possible water leaks. After the initial inspection was finished some light repair work was completed by our crew. Inspection, October 17, 2011: I measured the perimeter of the roof (40' by 35'), the customer would like us to redo the mesh and cement along the metal cap flashing as it is cracked in many places. There is a skylight that is leaking near the center of the roof and the diameter of the skylight is 3'. I did not find any splits or cracks in or around the skylight but the customer would like to have it resealed to prevent further leak issues. The roof holds water in large areas as can be seen in the pictures, he would like to know if these areas need to be replaced or are okay until he sells his house. There was a test cut done by another roofing company and he was told the insulation was soaked but he would like a second opinion. Judging by the water ponding and the discoloration of the cap sheet, I am led to assume that the insulation underneath is in fact soaked and probably needs to be replaced. grs pics 087 grs pics 088 grs pics 089 grs pics 090 grs pics 092 Roof Report, November 28, 2011: Attached are some pictures of the troweling work that we completed at this site. The whole perimeter metal flashing was cleaned off and re-cemented as per the customers request. The only thing left to do at this site is put in the new skylight (when it is ready). 101_0010 101_0011 101_0012 101_0013 101_0014 101_0015 101_0016 101_0017 101_0018 101_0019 101_0020 < End Report > CODE: 7908 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
