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 condominium in Edmonton required temporary roof repairs to mitigate water and wind damage. Several areas of the rooftop had missing shingles and a full inspection of the building was requested by the client. Temporary repairs are needed to prevent further water damage inside the units. Inspection, August 12, 2013: This location has severe wind damage as out lined in an earlier correspondence with the client.
- Specific to temporary repairs ordered, the area is approximately 10sq. of wind damage on 4 unit building (#64-#67).
- Above unit 65 was hit worst.
- Temporary repairs affected to 65 and others on block unit.
- No visual hail damage on vents or any metal.
- This is a 3 story back side and 2 story front side.
- The pitch is approx 6/12 with some being 5/12.
- The IKO brand shingle and product number A40490 color is weather wood.
Further observation of complex:
- Shingles missing and fascia and siding damaged to units 1 – 8, 24, 50, 80, 83 and 134.
- While working on unit #65 I could see that there was wind damage to unit #83, unit #50, as well as unit #10 (photos taken). I added 4 shingles while up there to stop the water from entering.
- Unit #50 & #10 I was unable to tend to them due to extreme weather conditions - they have similar areas as unit #65.
- Unit #128 was missing a piece of facia.
- Unit #138 was missing a a couple pieces of imitation cedar shake siding but there was no roof damage to this unit.
- There is a serious mishap with the nail lines for this complex, every area that has blown off has the nails too high – installation of shingles will not meet manufacturer recommendation.
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:

Article: Roof Snow Removal Edmonton.Below you will find a series of roof reports from the Edmonton roofing repair crew clearing snow from a residential roof to alleviate leaking. The client had a shingle roof on a two-storey building. Roof Report, January 22 2011: I checked the roof for leaks and determined water was getting into the soffit due to an ice dam on the upper right side (facing the backyard). The attic inspection showed that all appeared to be well except the vent running along the roof ridge was plugged and not working. After discussing payment, we cleared the lower roof of snow and ice damming. The upper roof at this time of the day was unsafe. Firstly, the cooler temperature results in harder snow, and secondly, there was water under the ice dam that spanned 4.5' up the roof. We will attempt to clear this area tomorrow. Roof Report, January 23 2011: As we had anticipated yesterday, our crew was able to finish clearing all the snow from the roof. This client should not be experiencing leaks anymore. < End Report > Code: 14875 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

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.
