Edmonton Industrial Liquid Rubber Roof Recovery, August 2014

This is the second part of a project for this industrial client in Edmonton. A full liquid rubber roof recovery was requested for this part of the project. The previous article detailing a downspout installation can be found here. Roof Report, August 22, 2014: We installed all of the units except for one and all of the penetrations are done on the shop roof (18 units and about 50 penetrations). All units were meshed and sealed with liquid rubber. Tomorrow we will get all the seams completed which is about 2100 ft. 20140822_104304_resized 20140822_104330_resized 20140822_104356_resized 20140822_110144_resized 20140822_110148_resized 20140822_145401_resized 20140822_145440_resized 20140822_150127_resized 20140822_152747_resized 20140822_161413_resized 20140822_161436_resized 20140822_161449_resized_1 20140822_161516_resized 20140822_161528_resized 20140822_165934_resized 20140822_165941_resized 20140822_170016_resized 20140822_170304_resized 20140823_115436_resized 20140823_133815_resized 20140823_170902_resized 20140823_170927_resized 20140823_170929_resized 20140823_170944_resized 20140823_171038_resized 20140823_171118_resized 20140823_171123_resized 20140823_171134_resized 20140823_171151_resized 20140823_171234_resized 20140823_171418_resized Roof Report, August 23, 2014: Today we got most of the seams done on the shop roof.

About 30% of the prep is done (will be done tomorrow) and we should start rolling out our coating tomorrow as well. The site will be complete on Tuesday. Roof Report, August 25, 2014:
Today we finished all of the units and penetrations on the office roof. We also have half of the roof rolled in. We are on schedule for site completion tomorrow.

Service Follow-up, September 8, 2014: Our project manager sent the following email to the client as a follow-up:
Morning, With the moisture I thought I'd check in quick and see how the roof is performing and if there are any issues? Thanks
The client had no issues as the liquid rubber installation kept all moisture out of the roof and building. < End Report >

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.
