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.

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.
