Commercial Tar and Gravel Flat Roof Leak Repair Edmonton, November 2015

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.

The client was the owner of a multi-residential apartment unit.
20151119_135416
We started by sweeping away rocks on the flat roof to look for the potential causes of water that was leaking into the building.
20151119_135419 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.
20151123_120414
We eventually found a few holes throughout the roof that needed patching.
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.

We removed a unit off-site at the building manager's request and patched over it.
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.

Commercial EPDM Roof Replacement, October 2015, Saskatoon, SK

This client in Saskatoon contracted GRS to send out a crew that could replace their currently flat roof with a new EPDM system. The team went on location to rip out the old system and installed the requested EPDM without any issue.   Roof Report: October 7, 2015 This day, the crew arrived on site for 7:00am and began to rip off the existing roof system. The other team members didn't arrive until a short while later, right around the time that the crane showed up with the site materials. Between 12:30 and 12:45pm, the team loaded the roof and found that the order was missing insulation and seam plates. The site lead had to leave the site then, to pick up the missing supplies. By their return at 3:00pm the remaining team had torn off enough of the roof to expose some rotten plywood underneath. This too, had to be replaced, so another member of the crew was dispatched to pick up some replacement sheets. In the meanwhile, the on-site crew put down the ISO insulation boards and began gluing the rubber to it. It was around that time (~5:00pm) that the temperature began dropping below what the normal threshold for the glue's application permits, so the team weighted down the EPDM for the night and prepared the site for the rubber's adhesion the following day.  
20151007_124904
We started the roof replacement by ripping out the existing system. The roof surface consisted of plywood boards.
20151007_152321
Some of the plywood boards on the roof were rotted to a point where there were holes in the assembly.
20151007_181009
Damaged pieces of plywood were replaced and we prepared to install ISO over the structure.
20151007_185222
Bonding agent was applied to the underside of the EPDM and installed over the ISO boards.
    Roof Report: October 8, 2015 The crew assembled once more for 7:00am and got to ripping out the rest of the roof as the sun began to rise higher into the sky, warming up the site. When the roof itself was all torn out, they laid the EPDM's ISO insulation and then adhered the rubber atop it. This work carried on through the day, so that by the time they were prepared to leave the site, all of the rubber had been laid down and some of the plywood had been installed to the parapet walls where it had required replacing. The following day would only require some detail work to some curbs and seams. They expected that everything would be completed by 3pm and the site would then be entirely finished.    
20151008_170637
After ripping out the existing structure on the second half of the roof, we mechanically fastened ISO boards.
20151008_170709-1
More mechanical fasteners around the perimeter of the roof.
20151008_170720
We applied rubber seam tape over the perimeter of the roof to prepare to install the perimeter flashing.
20151008_175840
Completed flat roof EPDM installation.
      Roof Report: October 10, 2015 The crew finished the roof on this day, but not without a little bit of trouble during the process. One of the subcontractors hired on for the job was not able to carry out the metal work that they'd claimed, so a replacement had to be found on short notice. The replacement arrived on site and completed the metal work in a timely fashion that also measured up to the exacting standards on any GRS project. With the metal work done, the site was cleaned up and the crew departed, leaving this another completed site bearing the GRS stamp of approval.
20151009_174044
To wrap up the site, we finished the metal work, including the perimeter flashing.

EPDM Roof Restoration with Liquid Rubber Coatings, September 2015, Edmonton

GRS first carried out an inspection and some light repairs on this commercial building's EPDM roof in April of 2012. There are two roofs in this system, one EPDM and one metal. We began working on the roof in September of 2015, proceeding with an engineered liquid rubber coating, on top of repairing any new fault areas that have developed since then. Check out this page for the original inspection information, though it may be referenced in some sections below.
Table of Contents:
Inspection
Scope of Work
Roof Reports [all 2015]
  Inspection: April 17, 2012 The original inspection is very thorough and worth reviewing. In summary, the EPDM and metal roof was suffering from some puncture holes, leaks, and membrane degradation. The structure itself is sound, but could use some maintenance to address then-current and future problems. Spot repairs could be carried out, or the roof could be recovered with a new watertight system (ie: liquid rubber).   Scope of Work: September 7, 2015 The crew made a list of things to present to the client, covering all of the pertinent safety information and everything needed to demonstrate that the scope of the project has been thoroughly considered. Below is a copy of everything they were prepared to cover.
Required on site to show HSE Manager:
  • GRS tool box documents
  • MSDS (attached)
  • WHIMIS tickets.
  • First aider with ticket
  • Fall arrest tickets
  • First aid kit
  • Pylons and caution tape for 6' control zone
  • Harnesses and ropes
  • Proper safety glasses
  • Steel toe boats (with green triangle symbol)
  • Long sleeve shirts
  • Gloves
 
Other:
  • Liquid rubber - 15 - 17 pails
  • Rollers, sleeves, brushes
  • Seam tape
  • Flashing mesh
  • Pressure washer, hose, electrical - be sure to advise office staff that roof may leak while washing.
  • Rags (materials to dry roof)
  • EPDM repair materials and tools
 
Notes:
  • Access to roof is with roof door - walk out on roof. Do not use ladders to access roof.
  Scope of Work:   Roof 1. EPDM ballast roof restoration. Approximately 36' x 50'
  • Remove rock ballast from half of EPDM roof
  • Wash EPDM roof membrane to white-glove clean
  • Repair EPDM as required
  • Coat half roof with liquid rubber (about 900 sq feet or 3 - 5 pails)
  • Return ballast to EPDM roof
  • Remove rock ballast from other half of EPDM roof
  • Wash EPDM roof membrane to white-glove clean
  • Repair EPDM as required
  • Coat half roof with liquid rubber (about 900 sq feet or 3 - 5 pails)
  • Return ballast to EPDM roof
  Roof 2. Metal Roof Coating. Approximately 56' x 50' Details first. Wash roof and/or internal gutters as required. Dry. Reinforce all your details with liquid rubber and/or seam tape or mesh as required before rolling out or spraying liquid rubber. Check all fasteners and replace as required or coat with liquid rubber. Check all rooftop penetrations, flashing, roof-to-wall connections, roof eave to gutter area, internal gutters and sheet metal connections, internal gutter to wall connections, and seams (especially horizontal) that may be separating. Clear old caulking etc. Add seam tape or mesh with liquid rubber. Coat complete metal roof, in gutters, and up parapet walls 30" in liquid rubber. Be sure to tape off a clean line at wall at a height of 30" or so - the line needs to be clean and straight. Pay close attention to internal gutters especially where sheet metal connects and where the internal gutter is at a vertical meeting the metal roof edge (that's where most leaks on these systems occur).

  Roof Report: September 8, 2015 The team met in the morning for a brief safety meeting with the entire crew present. They then went up to the roof to begin moving the ballast from the west side onto the east side, preparing the area for cleaning. Using pressure washers to clean off the surface, the team found some difficulty with the amount of clay mixed in with the dirt. They sent one of the technicians out to pick up more scrub pads that could handle the tougher soil. Heavy rain began rolling in, so the team had to depart a little bit early. Half of the roof is cleaned off and prepared for the following day's application of liquid rubber. Plan for September 9: Arrive for 7:00am, and put down the first layer of liquid rubber on the now-complete half of the roof. While it cures, the second half of the roof will be prepared for the same.

Pressure washers were used to clean the surface, which was covered in a mixture of clay and dirt.
20150908_150347
Scrub pads were used to remove the remaining soil. After the roof was dirt-free, we gave it a final wash.
20150908_150404
We had to shut the site down when heavy rain began to roll in. Half of the roof was cleared and now prepared for liquid rubber applications.
    Roof Report: September 9, 2015 The GRS crew arrived on site for 6:45am, and had their toolbox meeting for fifteen minutes until the client arrived to grant access to the roof. They began by clearing off the residual moisture and prepared to apply the liquid rubber to half of the EPDM roof. In the meanwhile, the other part of the team was at the shop picking up another six buckets of the liquid rubber solution. By the time they'd returned, the first team kept cleaning the metal roof. Half of the metal roof had liquid rubber applied to it, and the technicians kept preparing the gutter and sidewalls for recovery. Once the west side of the EPDM roof had cured, the crew moved the ballast back from the east side. They kept preparing and cleaning the east side for tomorrow's application of liquid rubber, as some rainfall prevented them from more liquid rubber application. Both the EPDM and metal roofs have been half-completed with liquid rubber, with the other half prepared for the following day's work. The customer also reported a heavy leak, which was traced and temporarily patched until it can be addressed at-length.

After cleaning the remaining portion of the metal roof, a second team of technicians completed the coatings after preparing the gutter and sidewalls for recovery.
20150909_071809
Various rooftop appliances also required coatings around their bases.
20150909_090516
Once the EPDM had cured, we applied liquid rubber to half of the roof which had previously been covered in residual moisture.
20150909_114826

  Roof Report: September 10, 2015 Work began on the roof around 6:45am, where the team got to cleaning the EPDM roof in preparation for more liquid rubber. Everything was cleaned and prepared for 10:00am, and after a brief coffee break one technician got to applying the rubber solution to the ribs of the metal roof while another applied it to the EPDM. The two remaining crew mates finished up the mesh and detail work on the metal roof, working through 12:30pm until lunch. Resuming at 1:00, they all continued with their assigned tasks until the metal roof was done around 3:00pm. The EPDM roof has a 5' x 36' section still requiring ballast removal, cleaning, and liquid rubber application. It's expected that the work will be finished tomorrow.
20150910_081808
After clearing the ballast rocks from the other half of the EPDM roof, we again had to wash off the clay/dirt mixtures from the surface.
20150910_101401
After washing the detritus, the surface was nearly ready for liquid rubber coatings. Scrub pads were used to remove any remaining buildups. One 5' x 36' section of ballast was still remaining, as well.
20150910_101450
Concurrently, another technician applied coatings to the remaining metal roof's ribs.

    Roof Report: September 11, 2015 The crew arrived on site for 7:30am, and got to cleaning the remaining section of the EPDM roof. By the time they took a break around 10:10am the roof was clean and ready for the liquid rubber. They performed a leak test on the second roof, and made sure that there was no water ingress to the offices below. Once confirmed, they prepared the breather holes on the metal roof's ribbing with mesh and rubber. Lunch break went from 11:30 - 12:00pm, and the EPDM roof was finished shortly after. The rubber has to cure before the ballast can be replaced, so the team moved on to the metal roof to continue adhering the mesh and rubber to the ribbing. Come 2:40pm, they had the site cleaned up and marked the job complete. < End Report >   CODE: 6621 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Photo Journal: Flat Roof Leak Inspection Edmonton AB, March 2014

Flat Roof Leak Inspection Edmonton - Below you will find a photo journal and emergency roof repair assessment from our Edmonton roofing repair crew at a commercial roofing site. Although the call began as a tar and gravel flat roof leak repair, the extent of damage escalated to the client requesting a quotation for flat roof recovery or replacement options. More field reports will be posted as they become available for this site. Regular Flat Roof Maintenance Will Save You Money. If you own a flat roof it is critical for you to conduct regular inspections, maintenance and repairs as needed. You will save considerable money if you do this twice per year. The reason it saves you money is that a complete flat roof replacement is expensive and 9 in 10 times had maintenance been done the replacement would not be required. If you do not do regular inspections and maintenance you could face a catastrophic failure which has occurred to this roof below. Simple spring and fall inspection and maintenance would have avoided a costly re-roof. Click here for a proper flat roof inspection and maintenance check-list. Emergency Flat Roof Inspection Edmonton, March 29 2014: Flat Roof Leaks. There are multiple large leak problems on this commercial tar and gravel flat roof that are currently being managed with buckets. Flat Roof Ponding. The roof assembly is carrying considerable ponding all over that is definitely a concern with dead weight load on the roof in times of sudden storms or in winter freeze thaw situations. Roof Drains. There are two drains on the roof that are useless; the previous contractors did not sump them properly. Roof Maintenance. Previous roof maintenance contractors did not remove the gravel before using tar to patch spots that needed repair. An excessive amount of tar has also allowed trapped air to cause blistering. Gum Boxes. Four gum boxes were actually near open water, and it was able to get into them. This is also contributing to some of the leaks. Roof Membrane. The tar and gravel roof membrane has become weather cracked from the sun, contributed by an improper ballast spread. If the pea gravel is not covering the bitumen layers the UV of the sun will dry out the bitumen causing it to crack and ultimately leak. Blisters. There is mass blistering of the roof membrane in multiple areas. If they continue, water will enter there as well. Several of the blisters on the roof are cratering water into them. Temporary Flat Roof Repairs. While we were on-site, we attempted to drain as much water as possible. The client called off the temporary repairs since the problems have become greater than simple roof maintenance work. The client has requested a quotation on roof replacement or recovery options.

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.
20150601_104710
We cleared gravel away from sections of the roof that we suspected water was entering through.
20150601_110050
Tears were found in some parts. We used SOPRAMASTIC to seal them in.
20150601_121144
Here is another exposed section which had been a tear running over a significant section of the roof.
20150601_115104
After spudding the tear, we applied mesh over top.
20150601_120319
A second coat of spudding was then applied over the mesh.
20150601_124628
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.

Photo Journal: TPO Flat Roof Recovery and Sloped Insulation in High Level, AB

Below you will find a photo journal from a commercial contract in High Level, Alberta. The work entailed a TPO flat roof recovery and sloped insulation. Background When a roof reaches the end of its life, our clients are faced with the choice of either a full replacement or a recovery. Roof recovery refers to applying a new system over an existing one when the roof is reaching its end-of-life (1). Depending on climate conditions, preference, or preexisting solutions, a roof recovery may be performed using TPO, EPDM, bitumen, cap-sheets and/or asphalt. Sloped insulation refers to the tapering that exists on an insulation system. As a weatherproofing measure, when precipitation reaches your roof, it will run off into the drain system down the slope. Call us today for a consult on which roof recovery system is right for your commercial, industrial, or residential environment. < End Journal > Code: HIGH Article Topics: TPO Flat Roof High Level Alberta.
