Edmonton Commercial Flat Roof Replacement, August 2012

This client in Edmonton required a complete flat roof replacement on a multi-family apartment building. An initial inspection was carried out by our crew followed by a complete roof replacement to prevent further water damage. Note: This report also contains additional follow-up service reports.
Inspection, August 30, 2012:
I have measured the apartment building, and have attached photos of the measurements, along with the possible problems regarding the leaks. There are a number of bubbles scattered over the roof, with the biggest bubble being roughly 12 feet long. It is a flat roof (tar and gravel), and by my estimation the current tar and gravel roof is roughly 20-23 years old. As the gum box is in pretty rough shape, I tried to picture as many of the bubbles as I could. However I lost track of them as there are roughly 8 bubbles over a 20' by 20' area. The corners of the building look okay, as do the surface of the pipes. I did not want to disturb the tar and gravel too much as I did not want to cause another leak. I am surprised there is only one leak. With the bubbles being scattered over the roof it would be hard to tell which bubble is causing it, and in time there will be more leaks.

Follow-up Snow Removal Service, March 31, 2013: This was a snow and water removal service call. There was only a small spot of snow and the rest was water. Water covers almost all the roof except where there was a drain or scupper. The average water level was 2' and was removed by pushing the water in tandem with snow shovels. Edmonton-20130207-00396
Follow-up Inquiry, June 4, 2013: Our project manager sent the following email to the client regarding a possible water leak issue (her response follows):
Hi,
I've had some time to sort through your inquiry earlier. I had a tech attend and the roof is extremely sound. It is possible, depending on timing over the weekend, that somehow when the crew attended to do the roof that somehow water got in somewhere. But the roof as it stands now is extremely and unusually sound. And as far as what you previously viewed with those flashings (the comment that the roof may not be done from your previous).... I have no idea how those came off the roof and I don't even want to venture a guess but my roofers re-fastened and all is good. Notwithstanding, here are some points of clarification or future discussion: IF THE ROOF EVER LEAKS AGAIN (or it appears to be the roof at all for any reason) have whomever it is call me the second they see an issue. This is critical so I can assess. I have a suspicion that a roof drain is leaking somewhere in the plumbing and in ideal conditions it will leak. A theory of mine is that when the crew attended and they they pumped water off the roof (and directed it down a drain), this is when the leak occurred - which means there is a breach in the plumbing at a drain (if I am correct). Also, the roofers did mention that at some point you should consider either scuppers at the edge of the roof on each side with a downspout or alternatively more internal drains. They commented that when they attended to re-cover the whole roof that there was a fairly good amount of ponding which isn't good. Internal roof drains are very expensive due to the plumbing costs but external scuppers at 2 or 3 sides would be much less (like 10% of internal drains). The cause of this is that over the years a building settles and isn't level so either more plumbing drains are added or exterior scuppers. I think that about covers it for now. Be sure if there is any sign of a leak that at first sign they call me and we'll get over there at first sign to track the problem down and if we diagnose it's an internal plumbing connection to a drain we can coordinate the plumber for you at that time also. Thanks
Hi, Thanks for the information.  We did have our plumber attend the building yesterday and he did discover an issue with the plumbing in the lower unit, which has since been corrected.  We will keep an eye on it. Thanks so much for your quick response and I hope that we will no longer have any water problems. Regards,

Follow-up Service Dispatch, May 21, 2014:
We fixed a lot of seams that were split and also found some holes that are now repaired. One section was really bad and was ponding so I dried it out and applied new LR to the entire area. One vent was peeling around the base (I also fixed it). I then went through the whole roof with a fine tooth comb and fixed every deficiency with the LR.
Materials Used:
  • .5 pail of trowel grade LR.
  • 1 pail of roll on LR.

Edmonton Commercial Roof Leak Inspection, June 2012

This client in Edmonton required a roof inspection due to leaking that was occurring during heavy rainfalls. This brief report outlines the initial inspection and includes photos of the site. Inspection, June 13, 2012: Upon arrival at the site we talked with a manager who directed us to the roof hatch and the damaged office area. We spoke to the person whose desk was directly under the leak, and he noted that the leak only occurred when there was very heavy rain. All vents in the problem area described were inspected. The plastic cement was also inspected and it appeared to be solid. We determined that the large unit in the area was the source of the leak (we calculated it to be directly above the leak area). We scraped the gravel from around the unit and lifted up the flashing in order to get a better look, and to expose the area for the incoming rain. After the rain had passed, we inspected both the unit and the office area. No leaks were found in the office area. We swept the pools of water around the unit onto the unit itself, trying to provoke a leak, but there were still no leaks. This led us to conclude that there were no leaks in the roof, and the leak that occurred previously was due to the rain being so heavy that it must have overflowed into the unit itself; if there was a problem with the roof, then the rain today would have exposed it.

Edmonton Flat Roof Repair and Inspection, October 2011

This report follows an inspection request from a client in Edmonton who was concerned about possible water leaks. After the initial inspection was finished some light repair work was completed by our crew. Inspection, October 17, 2011: I measured the perimeter of the roof (40' by 35'), the customer would like us to redo the mesh and cement along the metal cap flashing as it is cracked in many places. There is a skylight that is leaking near the center of the roof and the diameter of the skylight is 3'. I did not find any splits or cracks in or around the skylight but the customer would like to have it resealed to prevent further leak issues. The roof holds water in large areas as can be seen in the pictures, he would like to know if these areas need to be replaced or are okay until he sells his house. There was a test cut done by another roofing company and he was told the insulation was soaked but he would like a second opinion. Judging by the water ponding and the discoloration of the cap sheet, I am led to assume that the insulation underneath is in fact soaked and probably needs to be replaced. grs pics 087 grs pics 088 grs pics 089 grs pics 090 grs pics 092 Roof Report, November 28, 2011: Attached are some pictures of the troweling work that we completed at this site. The whole perimeter metal flashing was cleaned off and re-cemented as per the customers request. The only thing left to do at this site is put in the new skylight (when it is ready). 101_0010 101_0011 101_0012 101_0013 101_0014 101_0015 101_0016 101_0017 101_0018 101_0019 101_0020 < End Report > CODE: 7908 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

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.
