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.
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.

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.

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.

Flat Roof Repair Edmonton Mastic Patches June 22, 2015

Article: Flat Roof Repair Edmonton Mastic Patches Used to Patch Leaks Around Rooftop Drain.

Below is a brief article on patching leaks on a BUR flat roof in Edmonton. Our crew had to locate leaks and patch them using mastic and reinforcement mesh. to prevent anymore leakage from occurring. Thursday June 18,2015 Crew arrives at 11408 Jasper Ave to Complete Repairs.

11 am arrive on site. I had 4 guys on site when we first got there. We had to  search for the leak for awhile, the leak was above the drain in the center of the roof. Once we shoveled back the gravel and located potential leak spots. We then had to patch the leaks with mastic to prevent any further leakage. For this we covered the leak with a layer of mastic. Once the first layer was down, we then cut reinforcement mesh to place on top of the layer of mastic. We then covered the mesh with one last layer of mastic to seal in the mesh that we installed.

Temporary Flat Roof Repair Edmonton, June 15, 2015

Article: Temporary Flat Roof Repair. 2 Ply SBS Modified Bitumen Torch-On Roof.

Below is a short roof report that shows temporary emergency roof repairs using mastic to a flat roof in Edmonton, Alberta on a 2-Ply Mod Bit Torch-On System. Normally when we attend to flat roof repairs, the goal is to either perform repairs that have a high probability of lasting for some time or replace the roof. In some instances, our customers do not have it in the budget to either do the repairs properly or replace the roof. Often they have a replacement budgeted for the future. In the instance below the customer wanted the least expensive option to simply stop the leaks until he/she could finance a roof replacement. A quote for much more extensive repairs was provided but declined. January 20, 2015: Crew Arrives On-Site To Complete Repairs.  Originally the client had one leak on a goose neck vent. After further investigation it seams that another has started in a dryer vent. The crew fixed both the leaks with sopramastic and mesh. The customer looked at our work and was very happy with what was done. Man hours: 3 total. Materials:
  • 1 gal can of mastic.
  • 8 ft. of 6 inch mesh.

Flat Roof Leak Repair Edmonton, January 22 2015.

Below you will find a report from the Edmonton roof repair crew for a commercial car wash roof located in Sherwood Park. There had been a flat roof leak. I met the crew on-site and went up to the car wash roof, where I found water was pouring through a curb on the concrete deck. I checked the curbs in the area leaking and found nothing. Then, I expanded the search and found an anchor installed through the roof membrane that was improperly sealed off. I installed a lick of gum over the problem area and asked the client to call me back if the problem persisted. Please note that this is only a temporary repair and we should return to check if the improper sealing was actually the cause of the leak. < End Report > Code: 2000 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Edmonton Flat Roof Repair, April 2014

The following report details some quick repairs made to a residential flat roof (tar and gravel) in Edmonton. The current system was blistering and required maintenance. We delivered a quotation for the customer's flat roof, covering both temporary repair and full-replacement options. They requested that we perform the temporary repairs to the affected areas, so we scheduled them for service to be carried out shortly. Roof Report, April 24 2014: When working on site, the roofing technician reported that there were some serious fault points in the existing roof membrane, such that the blisters "resembled blueberry fields". After clearing spots of the gravel, they attended to these blisters by repairing them with sopramastic, reinforced mesh, and poly plastic. The six vent areas believed to require replacing were in better condition than had originally been assessed, so only three of them required attention. They were removed and replaced with new ones, each of which were nailed in and sealed with the same sopramastic, mesh, poly plastic that had been administered to the blistering portions of the membrane. With these repairs completed, the job site could be wrapped up and the team departed shortly after. 20140422_122247 20140422_122249 20140422_133115 20140422_133124 20140422_133131 20140422_133254 20140422_133257 20140422_133306 20140422_134932 20140422_135006 20140422_135010 < End Report > CODE: 8930 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Edmonton Residential Skylight Repair, March 2013

This client required a skylight repair service on his residential rooftop as there was water ponding around the skylight. A crew member was dispatched to perform the repairs. Future maintenance will be done by GRS if necessary. Inspection, March 2, 2013: The problem with this site is that water is ponding around the skylight and leaking into the home. The skylight is only 3 inches high. I have advised the client that water is getting behind the stripping around the skylight. I also advised that the curb must exceed 8 inches above roof level. The skylight is 58 inches by 90 inches.

Drayton Valley Commercial Roof Leak Repair, June 2011

This article covers a commercial leak repair in Drayton Valley and also includes a follow-up service call. Photos relating to both service calls are supplied. Roof Report, June 7, 2011: First I met with the manager on-site and examined the leak areas from the inside. Then I went onto the roof and began examining the suspect areas around RTU (rooftop unit) #4 and RTU #6. I found loose curb stripping under the flashing but was unable to repair at that time due to heavy rainfall. I advised the manager that I would return the next day. Roof Report, June 8, 2011: I informed the staff on-site that I would be working on roof. Then I went onto the roof and removed and replaced the flashing. Lastly I repaired the stripping with ModBit compatible mastic (2 tubes).
IMG_0682
Significant leaking had entered the building through the roof and had visibly stained many of the ceiling panels.
IMG_0718
The inspection revealed crumpled base flashing, an unfastened termination bar, and exposed seams on the roof surface around a unit.
IMG_0717
For the first unit, we removed the base flashing and applied liquid rubber around all of the seams.
IMG_0713
Clear water staining on the roof surface around this unit, with a small trail leading into it. This indicated where leaks were entering into the building from.
IMG_0711
The leak lead to an exposed seam underneath the unit, which was slightly tearing apart. We applied coatings over the deficient sections.
IMG_0704
The same process was repeated for the second unit. We completed removed the old flashing to expose the base.
IMG_0712
After coating over any tears along the seams, or pockets
IMG_0710
As with the other unit, there were clear paths of where water was entering from into the building.
IMG_0692
The edge of the roof had significant waterpooling, indicating that it was not sloped correctly or the drainage systems were failing.
IMG_0691
Another pattern of entry could have been a critical amount of standing water leaking through the base of these vents.
IMG_0689
Most of the roof had significant tearing along its seams, and there were signs that water had been standing throughout the roof -as indicated by these white stains.
  Follow-up, June 12, 2012: The following email was sent by the client's maintenance manager prompting a follow-up service call:
In speaking with the store, water seems to be entering the store when it rains. From the description the manager noted, it seems the curb flashing on one of the roof top units may require attention as the water is running along side the supply air duct work that protrudes through the roof. Our HVAC vendor was on-site in May to complete an inspection and had not noted there to be any obvious concerns at that time. However, they are not due back until mid-July or so. The area is to the right hand side of the check out area. One ceiling tile is obviously wet. It would be appreciated if you may confirm to have your roofing vendor out within the next day or so while the weather is favourable to make such a repair. Once complete, please do ensure to have any interior water damages as results (ie, water stained or missing ceiling tiles) addressed. Please do advise as to your roofer's anticipated arrival. For the time being the store has been putting a bucket in the area to catch the water whenever it rains. Regards,
Roof Report, June 13, 2012: We arrived on-site and inspected the damage from the inside. After gaining access to the roof, we identified the problem area as being an HVAC unit near the southwest corner. To determine exactly where the leak was coming from, we performed a leak test. We brought buckets of water up onto the roof and splashed it all around the HVAC unit. A total of 8 buckets of water were used in this test, but we did not manage to find the problem. It was determined that in order to accurately find the leak we would have to wait for the rain to come. The downspouts appear to be crushed near the bottom, and the northern most down spout seems to be half missing. The pooling of water by the downspouts has to do with the location; the parking lot asphalt where the spouts are is sloped in a way that the water pools by the eastern wall of the building.
IMG_1875
Water ingress had occurred during rainfalls. Although not as significant as before, some ceiling panels were once again stained by the leaks.
IMG_1876
We inspected the attic again for signs of leaking around the newly stained panels. This would help us pinpoint where water tests ought to be performed on the roof.
IMG_1877
One of the downspouts was crushed near the bottom, with rusting all throughout.
IMG_1879
The downspout on the northern side of the building was half-missing. On both accounts, water was pooling by the wall due to the slope of the parking lot.
IMG_1880
We went back to the roof to do some water testing. The leak entry point was pinned down to an HVAC unit in the southwest corner of the building.
IMG_1883
Since the client had not approved a roof recovery, replacement, or re-sloping, we had once again found significant waterpooling on the roof. However, water was not entering the building through the vent it was adjacent to in this case.
IMG_1884
One of the candidate units had some standing water around its base, as well as over a run of exposed seams on the roof surface.
IMG_1885
The flashing around the unit also had to be sealed in. Parts of the membrane around it had been forming bubbles or was beginning to curl upwards at the seams.
IMG_1890
Furthermore, the coatings that were originally applied over the seams were past their age.
IMG_1898
Water testing was performed to see what route it would take around the HVAC unit and into the building.
IMG_1904
Eight buckets of water were used for testing around the suspected units.

Roof Retrofitting in Unity SK, August to October 2010

Below you will find a series of Roof Reports and photos from our roofing repair crew in Unity, Saskatchewan. The client asked us to perform some retrofitting and approved some assessments that were made on-site. Roof retrofitting and leak mitigation was provided.

Roof Report, August 24 2010:

We opened one ventilation unit which was found to have traces of moisture. It was water-tested, which came back positive as a leak area. We also found areas that had open wire penetrations and gas lines going into the building. A cut-test was also performed, where 4-ply styrofoam insulation (5") and a vapour barrier was found. This might explain why water had to travel some distance before it appeared as a leak, since the rest of the roof is in good shape. Areas requiring maintenance were sealed with mash, mastic and additional caulking as required. Client Callback, October 21 2010: After TPO recovery, the client found more water leaking at grade-level. We resolved the issue with caulking around the problem area. < End Report > Code: 120 Contact Us Call our 24 Hour Emergency Roof Repair at 1.780.424.7663.
