Below you will find a routine leak repair service call for a commercial client by our Edmonton roofing repair crew. The following reports underline some of the work we do with other contractors and trades, such as plumbers. Inspection, November 19 2015: We began to sweep the rock layer on the flat roof to expose the surface so that we could start looking for leaks. After speaking with the building manager, our crew has been asked to wait for a plumber before we inspect the drains. The second part of our inspection entails what units need to be removed. Roof Report, November 21 2015: Today the crew removed more gravel from the roof. A couple leaks were patched up. The site manager gave us the go-ahead to remove one unit from the roof. Roof Report, November 23 2015: Today we shoveled more rock from the roof to find more holes that needed patching. Once it started snowing, we covered the roof and shut down the site. Roof Report, November 25 2015: We removed the one unit that the building manager had requested to be taken off-site. We also started working on two drains but were later informed that the owners were having all the pipes replaced, including on the other two drains that we were not given permission to begin work on. The remaining two pipes were added to the work order and we will have to wait until they have completed the pipe replacement before proceedings. Roof Report, November 26 2015: We are still waiting for the plumber so that we can proceed with the inspection and maintenance on the remaining two drains. This site should be completed on Saturday. Site Completion, November 30 2015: We finished the site today, on schedule. The remaining two drains were replaced, which we had to add to the original work order. Another possible leak location was sealed. As well, any metal that we removed from the walls was reinstalled. Another rooftop unit was disposed of, as well. < End Report > CODE: 106A Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

This article is a continuation of work done for the same client. The report follows service calls that occurred after the initial EPDM installation.
- 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.
- 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.
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.
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.

This report covers a leak inspection and repair carried out by GRS to one of our commercial client's metal roof system. We had to look through insulation and drain away some collected water from the ceiling. Inspection: December 21, 2013 We isolated the leaks to the southwest (about 20') and east (40' - 50') corners of the upper roof near the gutter systems. There was ice and snow buildup that had to be cleared away before a rooftop investigation could continue, so it was dealt with and we confirmed some potential areas for water ingress. The team also removed insulation from the ceiling one piece of plywood from the wall to inspect the area underneath the gutters. Findings: There was a great deal of moisture on the back of metal roof panels (that even poured out a bit when insulation was removed. The standing seam was wet to the touch (on the interior) and nearly dripping. This was likely caused by the amount of ice overfilling the gutter by 2" or more. There is also a possibility that the downpipe and gutter connection is leaking. In cases such as this, it could be that water freezes in the pipe, creeps over the connection, and seeps into the walls when it thaws out. Both of the leaks reported seem to stem from the same cause, which leaves us hopeful that repairs can be made to one location and prevent the problems in two. We advised the client of these possibilities, but informed them that there may be a few attempts made over the course of the season, considering the existing ice makes for difficulties in the repair attempts. For the time being, snow can be removed from the building's roof and EDM applied to the potential problem sites as a temporary fix to tide the client over until warmer weather arrives. < End Report > CODE: 5611 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

This client was in the process of purchasing a new home which had several missing shingles. A request was made to GRS for an inspection and estimate to replace the missing shingles. Inspection Notes: There are 5 missing 3-tab shingles which need to be replaced, as well as nails to refasten the metal fan vents, and rubber modified bitumen to seal off exposed nails in the anchor points and roof fixtures. If you decide to hire us to fix the roof, we will be able to match the shingle style and colour, and I should be able to repair the roof within the same day as I receive the work order. There is no Ice and Water Shield along the eavestroughs or valleys, but in order to install this the roof would have to be replaced completely. If you have any questions you can respond to this e-mail or please call me on my cell phone. The repairs were made successfully and the client sent the following email expressing her pleasure in our work:
Good morning, Thank you for taking care of the roof repairs so quickly. When you have a chance can you let me know what all you did and if I need to follow up on anything other than the ice shield. Thanks again.< End Report > CODE: 15624 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

Below you will find a series of reports from the Grande Prairie roofing repair crew. Initially, they had been called in for snow removal on a condominium complex flat roof. This culminated into further inquiries for a roof replacement in the summer season. Inspection, January 18 2011: The scupper drains on the north and south side of the roof were blocked with ice, and the drain pipe was frozen. I suggested to disconnect the frozen pipe, clean the ice out of the scupper, and clean the snow off the roof. The client gave their approval following our observations. As far as cleaning goes, this roof should be easy, as there are many areas to throw the snow off from. Roof Report, January 19 2011: I arrived at 8:30am and cleaned approximately 5,000 to 6,000 sq. ft. of snow from the client's flat roof. The ice was cleaned from the two scupper drains as well, followed by an ice melt application. Service Followup, January 20 2011: Although the snow removal is complete, the client still has frozen drain pipes. The north scupper seemed to be running when I left the site. There is an internal drain on the south side that will be helpful when water starts to accumulate down on that end. Leak Investigation, January 27 2011: The drain on the south side needs to be repaired with torch-on and SOPRAMASTIC. Our client also inquired about a roof replacement for next summer. Roof Report, January 29 2011: Based on our investigations, we carried out a drain leak repair with a torch-on membrane. Mastic was applied as a sealant. Eventually this drain will require a replacement. Quotation, April 4 2011:

This Edmonton client required repairs to an existing built up roof system. Some areas on the roof appear to be blistering and others have ponding water. A crew was dispatched to perform the repairs once the weather was suitable. Note: This report contains several separate repairs and maintenance reports completed at different times.
Scope of Work: Repairs to Existing BUR – Built Up Roof System.
Scope of Work: Repairs to Existing BUR – Built Up Roof System.
- 7 areas of the roof have blistering that requires repair.
- 3 areas of the roof have ponding that requires repair.
- 2 units show water penetration to the interior.
I told our site contact that as soon as we have a good break in the weather we would be back to source the leak. She also asked me to check how the drains were, which were exposed and working fine. The client then showed me interior cracks in her ceiling, which with the amount of snow on the roof are more than likely due to extra weight on roof. She told me their condo board has no money to pay for snow removal and they would take care of it themselves.
Annual Maintenance Follow-up, April 25, 2012: Arriving on site we walked around the building to look for any signs of potential problems ie. open mortar joints and general degradation, and nothing stood out. As we entered the premises interior ceilings and walls did not show any signs of water damage/problems. Once we proceeded to the roof there was nothing that stood out. Closer examination showed some caulking drying up and cracking. We proceeded to caulk all units/protrusion on the roof and also caulked all seams and screws on the parapet flashing. There were a few minor repairs needed near the scuppers. We used MS Detail to do these repairs. Otherwise the BUR portion of the roof showed no signs of any deficiencies, such as blistering or ridging etc. Once the body of the roof was inspected for these deficiencies we then proceeded to broom the entire roof. We would level out gravel where the wind around some units would push the rocks away and create a bare spot which would be open to exposure/ UV rays. Then we leveled out the gravel on the entire roof looking for low spot and making sure they were covered. There are only two areas of concern. The first is the shingles under the scuppers; they are badly worn and are in need of replacement. The second is the gyp rock cover the hatch door. It came off when we opened the hatch, we would have fixed it but it had been re-screwed back on so many times that the edges of the gyp rock were nothing but torn paper. There were several different types of nails and screws around the edge to further indicate it was repaired many times. Roof Report, June 20, 2012:Removed 18 inches of gravel around vent. The plys are wet and soft so we applied 12" of plastic cement around.
Annual Maintenance Follow-up, January 30, 2014:
An email sent from our project manager to the client:
Hi, Our report, that was copied to you, determined that there are a number of areas of concern that will cause leaks; 1. Areas such as the caulking on the heat stacks (you don't need to call anyone to replace heat stacks) - maintenance issue. 2. Ice damming glacier effect - again maintenance. The previous repairs are not the issue. You have a failed roof that is going to fail in a number of areas at any time, as with this report. When the roof fails the leaks will manifest on the inside at the lowest points, the same points as always because water finds the lowest point in that area and manifests. Did you want a work order to have repairs done? Thanks
This project may be updated at a later date.
