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.

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.

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.

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.

Metal Siding Leak Inspection, September 2015, Edmonton

This client's commercial building bears a flat metal roofing system, but contacted GRS over some concerns that the metal siding around some windows on the upper level had leaked. GRS sent out one of its technicians to inspect the area and provide some advice on the repairs that could be carried out. Inspection Report: September 29, 2015 The technician went on-site and met with the client to discuss the problems with water ingress around the windows on an upper level of the building. They went out to the metal roof and began inspecting the windows and surrounding walls. The leaking areas became quite apparent, and the whole wall could use some patching. The reporting technician then suggested that every window's corners be treated with caulking to divert the water away from the metal edges. This is due to the water's current path, which is to run along the metal and behind the wall. Their estimate was that two crew members would be on-site for a half-day and use around eight tubes of caulking to properly seal the areas. This would, however, be a 'bandage' approach; the proper way to fix the problem would be to first remove the metal around the windows, cut back the wall metal, apply seam tape or spray foam between the metal and the wall, then replace the flashing that has degraded to this point.

The client reported water ingress around the windows on the upper levels of the building.
20151013_151531[1]
While the sealant used around the sill had failed, and parts of the metal roof required patching, our technician suggested caulking applications around the corners such that it would divert water away from the existing coatings.
20151013_151556[1]
Here is another example of a portion of the window where water was forming pockets. The rusting is characteristic of water pooling for extended periods of time on the sill, and slowly leaking into the building over time.
20151013_151631[1]
There had also been some tearing at the end of the drip edge on the top of this window. Water had been entering through this hole.
WP_20150929_14_46_20_Pro
Some tearing in the metal siding on the roof had also been another potential leak entry point. The tearing had reached a point that the siding was becoming loose from the wall.
WP_20150929_14_48_39_Pro
Some components also required re-caulking around the base. Cracks in the old sealant had created small holes through which water could enter.
WP_20150929_15_05_58_Pro
There were also windows which had missing screws. Water had been entering the building through the screw holes.

Another example of a piping penetration requiring sealing.
WP_20150929_14_59_28_Pro
While our technician was willing to apply a "bandage", the correct approach would have been to spray around the affected areas with foam or seam tape, and then reinstall new flashing.
WP_20150929_14_56_50_Pro
After addressing the windows, we did some water testing around the perimeter of the roof walls to make sure that the seams were watertight.

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.

Edmonton Commercial Tar and Gravel Roof Repair, Feb 2015

This client had leaks coming through their commercial tar and gravel flat roof. The roof itself is in good shape, but was in need of very minor maintenance.
Table of Contents
Inspection (February 13)
Roof Report (February 21)
Investigation (March 6)
  Inspection: February 13, 2015 The client is experiencing a small leak in the roof 15' away from the front doors, which appears to be originating around an electrical conduit penetration through the roof. The penetration itself is some two feet from the roof edge, which is among the highest points on the roof (drains are in the center). It's believed that the leak could be one of two things. First, it could be leaking around the gum box (which is starting to crack) or second, where the stack is fastened to the roof. To fix the problem, we could first need to patch the gum box, and tighten up the bolts around the conduit and seal the area with some caulking. Otherwise, the 130' x 160' roof is in good shape, and only ten years old. 20150213_093523_resized 20150213_093536_resized 20150213_093608_resized 20150213_093610_resized 20150213_093658_resized 20150213_093707_resized 20150213_093708_resized 20150213_093712_resized 20150213_093740_resized Roof Report: February 21, 2015 The crew confirmed the problem area to be the gum box, caused by a few separate issues. First, the steel pipe had moved slightly under the weight of the wire hanging off the pipe itself. Second, the crew that had installed the pipe and/or roof only filled the gum box one-quarter full of gum and three inches of insulation filler. Over time, the gum began to dry, crack, and settle; allowing water ingress and ponding. The gum box was emptied of the previous solutions and filled 3/4 with pourable sealer, which should now be a permanent solution to the problem. As a precaution, we added a bead of lap sealant around the base of the gum box and a bead of high-quality caulking around the metal support (which had metal bolts going right through the parapet without any sealer at all). IMGP2608 IMGP2609 IMGP2611 IMGP2610 Investigation: March 6, 2015 The client called us to assess the roof once more for three reported leaks in the northwest corner of the building. The roof is an EPDM ballast system, so gravel relocation is necessary to uncover root problems in these types of roofs. We sent out a technician to investigate the causes of these three leaks, for which they found two (need to search under ballast for the third). It would appear that there are two holes in the roof with a near-3" diameter that require patching. The third will be found during repair efforts. 20150306_154607_resized 20150306_155240_resized 20150306_155112_resized 20150306_155105_resized 20150306_154832_resized 20150306_154827_resized 20150306_154753_resized 20150306_154748_resized 20150306_154652_resized This report will be updated with repair logs as they come in.

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 Leak Inspection, December 2013

This report covers a leak inspection and repair carried out by GRS to one of our commercial client's metal roof system. We had to look through insulation and drain away some collected water from the ceiling. Inspection: December 21, 2013 We isolated the leaks to the southwest (about 20') and east (40' - 50') corners of the upper roof near the gutter systems. There was ice and snow buildup that had to be cleared away before a rooftop investigation could continue, so it was dealt with and we confirmed some potential areas for water ingress. The team also removed insulation from the ceiling one piece of plywood from the wall to inspect the area underneath the gutters. Findings: There was a great deal of moisture on the back of metal roof panels (that even poured out a bit when insulation was removed. The standing seam was wet to the touch (on the interior) and nearly dripping. This was likely caused by the amount of ice overfilling the gutter by 2" or more. There is also a possibility that the downpipe and gutter connection is leaking. In cases such as this, it could be that water freezes in the pipe, creeps over the connection, and seeps into the walls when it thaws out. Both of the leaks reported seem to stem from the same cause, which leaves us hopeful that repairs can be made to one location and prevent the problems in two. We advised the client of these possibilities, but informed them that there may be a few attempts made over the course of the season, considering the existing ice makes for difficulties in the repair attempts. For the time being, snow can be removed from the building's roof and EDM applied to the potential problem sites as a temporary fix to tide the client over until warmer weather arrives. image-1 image image-13 image-12 image-11 image-10 image-9 image-8 image-7 image-6 image-5 image-4 image-3 image-2 < End Report > CODE: 5611 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
