Ongoing Roof Leak Maintenance in Sherwood Park AB, May to July 2015

Assessment, May 7 2015: The site had a plumbing issue; the drain was backed up. Our client said if there were any roofing problems in the future, that they would definitely contact us. Surely enough, we received a call the next month. Scope of Work, June 1 2015: We are to locate and fix the leaks of a BUR roof and add one drain basket to the drain. When we got up to the roof, we had to locate two leaks which were both in the center of the roof but about 15 ft. away from each other. Once we swept all the gravel back, we noticed there had been two large gum patches that were previously installed by another contractor and had now failed. To test for failure, I pushed water out of the areas in the patch. We spudded both areas. One leak was 12 ft. x 1.5 ft. and the second was 10 ft. x 3 ft. Each tapered down to 1 ft. once both areas were spudded. Underneath, there were signs of water saturation, so we had to dry each area with a shop vac. Once dry, we then gave them a coat of asphalt prime to help the MASTIC bond on the BUR system. Once priming was complete, we then applied a coat of MASTIC to the entire system followed by a layer of reinforcement mesh. Another top coat of MASTIC was applied to seal in the mesh.

We cleared gravel away from sections of the roof that we suspected water was entering through.

Tears were found in some parts. We used SOPRAMASTIC to seal them in.

Here is another exposed section which had been a tear running over a significant section of the roof.

After spudding the tear, we applied mesh over top.

A second coat of spudding was then applied over the mesh.

We then let the second layer of spudding dry over the mesh.
Our second scope of work was to install a drain basket. Unfortunately, this could not be accomplished because it had been completely covered with MASTIC. There was nothing to fasten the basket to. Materials:
  • 25 ft. of 3ft. mesh
  • 3x pails of MASTIC roof patch
  • 1x can of spray primer
Followup - Installation Report, June 17 2015: After filling out safety documentation, we met with the client to go over leaks on the main roof when we had performed repairs on during the previous visit. From the client's assessment, there was still apparent leaking. A crew member went up on the roof and searched but could not finding anything. We will need to return when it is leaking actually occurs to get a better idea of where it is coming from. As for the roof above the restaurant, we tracked the leak to an air unit. Once we removed the metal, paper around the base was splitting and water was getting in, evidenced by moisture. We spudded the entire perimeter and applied a coat of MASTIC, followed by a layer of reinforcement mesh, and finally a top coat of MASTIC. We then reinstalled the metal and cleaned up the site.

Materials:
  • 2x pails of MASTIC
  • 25 ft. of 6 in. mesh
Quotation, June 23 2015:
  • SBS 2-ply patch along entire down-slope (60 ft. x 20 ft. patch)
  • Drain replacement with u-flows
Scope of Work: Remove all gravel in the area, spud out 10 ft. on either side of the drains, and 60 ft. down the low ride of the roof. Roll on asphalt primer and torch down the base. Add new drains with u-flows and cap the entire area. Materials:
  • 9x rolls of cap
  • 9x rolls of base
  • 10x gallons of asphalt primer
  • 2x 4 in. drains
  • 2x 4 in. U-flows
  • 2x pails of MASTIC
The client approved our quotation on the 25th of June:
Please go ahead with this job and let’s hope it solves our leaking issues.
Field Report, July 13 2015: We had our safety meeting and went up to the roof to shovel all the gravel away from the work-site and spudded the segments of interest in preparation of a patch. It started to rain and we had to call it a day.

Edmonton Residential Flat Roof Inspection and Repair, October 2013

The report follows a repair on a residential rooftop that is in fairly good condition. No leaking is present however there are issues with the penetrations on the roof as well as the flashing and vents. The home owner requires an inspection of the roof to pass and therefore needs the repairs completed immediately. Roof Observation Report: With respect to the request to observe the roof assembly at said location, the following are noted: The roof overall is in fair to good condition and looks to be approximately 10 – 15 years old. No leaks identified. No soft spots observed. There are however deficiencies with the penetrations on the roof. It appears as though the roofers installed the roof penetrations without a proper tie into the BUR and just graveled over the flanges. Hence, the lead flashing on the plumbing vent(s) is slowly sliding down hill and bending. Additionally, there is some minor damage at the front end of the house were the felt has been exposed to the sun and has dried due to UV and separated from the house. This will lead to leaks if not repaired. At the back of the house, there are some sun dried spots due to UV along the gable drip edge but this will not be an issue for another 1 - 2 years approximately. The roof definitely requires one plumping vent replaced and a small area of gum and jewt in the front of the house to pass inspection. The other vents are going to cause problems within the next 5 years or sooner. I would need approximately 16 – 24 man hrs. to replace the one plumbing vent and remove some flashing at the front of the house which would bring this roof to a “pass” condition. However additional time is required to properly install all penetrations (approximately an extra 32 - 38 man hours). 1 2 3 4 5 6 The crew arrived on site to begin repairs on the roof. The lead flange for the plumbing stack (completely cracked) was fixed. Next they spudded the field and installed a high top. Finally it was gummed and then poly was applied on top. Gravel was added for the finish. Materials Used:
  • 1x roll of Jewt (sopralastic reinforcement).
  • High Dome Flashing for 4" Vent.

Grande Prairie Multi-Residential Flat Roof Snow Removal, 2011

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:
