Residential Roof Leak Repair in Edmonton AB, July 22 2015

Below you will find an initial assessment for an ongoing residential site by our Edmonton roofing repair crew. More reports will be posted as they become available. Initial Assessment, July 22 2015: We arrived on-site at 1:00 pm and were lead by the client to two leaks in the shop. One was coming from around the skylight, and another one around the chimney stack in the middle near the edge of the roof. Upon inspecting the roof top-side, we observed that the acrylic MASTIC around the chimney was cracking and lifting in areas. It should be removed and replaced with seam tape and liquid rubber. The penetrations require the same. It is only a matter of time until it begins to leak around the entire skylight. There are also cracks and splits in the skylight, which seems to have had been coated with spray foam. The metal gum box also needs to be topped off. There is a metal boot top-side as well that looks like it was only spray foamed. The roof measurements are 85 ft. long by 51 ft. wide, and the skylight was 4 ft. x 4 ft. It should take 25 man hours to clean and repair the penetrations, apply some gum patch into the metal boot, and cover the foam/top up the gum box with rubber MASTIC. < TO BE CONTINUED > Code: 154 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

The following roof repair report explains a small repair job we completed in Edmonton Alberta. The repairs we needed to complete were filling in rooftop gum cups with mastic. Also we had to seal in a rooftop unit with seam tape and coat it with liquid rubber to waterproof it. Monday June 22, 2015 crew arrives to 12609 153 Ave Edmonton.

12:30 pm arrive on site. Filled out our hazard assessment and safety paperwork forms. The roof repair crew then went on the roof to begin the repairs. Once the crew was on the roof we filled three gum cups using mastic. There was also an rooftop air unit on the roof that the customer asked me to seal in as well. We sealed it in with seam tape and then coated it with liquid rubber with two coats.

We cleaned up the roof and our work site. The customer was happy with the work. We left the site at 2 pm.

Flat Roof Repair Edmonton – Gum Box. June 10, 2015.

Article: 2 Ply SBS Torch-On Low Slope Roof "Gum Box" Repair on Commercial Roof in Edmonton Alberta.

"Plastic pan - also called pitch pan, pitch pocket, gum box, these comprise a flanged collar placed around items that project through the roof system; the flange is properly set into the roof membrane and the pan is well filled with plastic cement; these pans are a constant source of trouble and should only be used when no other solution can be found." Source: Red Seal Roofer Program Website. February 13, 2015: Journeyman Roofer Attends for Roof Inspection.  Address 11754 170 Street Edmonton, Alberta.
The client is experiencing a small leak 15 feet in front of the front doors around an electrical conduit penetration in the roof.
The electrical conduit is two feet from the roof edge which is the highest point on the roof as the drains are in the center. I believe the leak could be leaking around the gum box which is starting to crack or where the stack is fastened to the roof. I believe the water is getting in through those holes and running back into the system.
To fix this problem we would need to first put a gum patch on the gum box and tighten up the bolts on the bracket that holds the conduit and seal around it with some good caulking.
Man hours 3 - 6 total with drive time and inspection time. Material 1 - 3 gal pail of gum. 2 tubes of tremco chalking.
Roof measurements 130 ft x 160 ft with two drain and 13 penetrations. The roof is approximately 10 years old and in good shape.

  February 21, 2015: Crew Arrives On Site To Complete Repairs. This morning we stopped by to confirm were the problem area was and that we had everything for the job.
Once we got back to site and went up to the roof I could tell that the water was coming in from the gum box.  A couple of things caused the failure, first that the steel pipe had moved slightly from being pulled by the weight of the wire hanging and that the crew that installed the roof only filled the gum box up 1/4 of the top with gum and had 3 inches of bat insulation filler.  Over time the gum began to dry and crack and settle allowing water to pond inside the gum box and leak through.
So we removed the gum out of the gum box and some of the insulation and filled 3/4 of the gum box with pour-able sealer, a permanent repair for the problem.  As a precaution, we also added a bead of lap sealant around the base of the gum box so that no water could pond there and installed a bead of high quality caulking around the metal support which had bolts going right through the parapet wall with no sealer.
Materials used: I tube of tremco caulking. 1 tube of lap sealant. 1 package of pour-able sealer.

Edmonton Commercial Flat Roof Repairs, February 2012

This client required repairs to their flat roof, and contracted GRS to carry out the service. We arrived for an investigation and were met with a roof report assessment from a year ago - many of the third-party's investigative findings stand true, and gave us an idea of the scope of work to complete. Inquiry Received: November 15, 2011 The client first called in looking for a quote or estimate on repairs that needed to be carried out on their flat roof system. We scheduled them in for a visit a few days later so that we could perform an investigation on areas needing repair. Investigation: November 17, 2011 We sent a technician out to the job site to investigate the client's identified areas for improvement. They presented a report conducted a year ago (via third party), giving the technician an idea of where to examine. Going up to the roof to double-check all of the locations, it seems like the problem areas still need to be addressed. That concluded the investigative stage, and we prepared to deliver a quotation. Quotation Delivered: November 26, 2011 After reviewing the third-party roofing report and undertaking our own investigation to corroborate their findings, we delivered a quote to the client for their consideration. The scope of the work covered the following (referencing scans from the report):

  Roof Report: February 23, 2012 The team arrived on site to work on the problem areas of the roof. One of the client's employees showed them the roof access hatch and left to continue with their work. The equipment was loaded onto the roof; safety equipment was checked and fully functional. One of the team members got to working on topping up the gum cups (five in total). The other member used their torching trowel to check all of the seams on the upper level. They are in good condition, as is the metal flashing. With that inspection carried out, the team departed the site briefly to procure some materials (storm collar, caulking, etc.). They returned to install the storm collar and seal it with caulking, then moved on to the lower section of the roof. One of the crew cleared the drain of debris, but snow, ice, and water build-up on the lower roof prevented further progress. This site will have to be revisited once the lower roof is dry and the weather is cooperating.
