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.

The client was the owner of a multi-residential apartment unit.

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.

We removed a unit off-site at the building manager's request and patched over it.
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.

Shingles Replacement and Plumbing/Ventilation Maintenance in Edmonton AB, July to August 2011

Below you will find a series of quotations and field reports from our Edmonton roofing repair crew. Our existing client approved our consultation for a full shingle replacement, system maintenance, and waterproofing. Quotation Request Received, July 28 2011: The client asked me to assess all five buildings in the condominium complex and give my recommendations for  each one. There are three 6-unit buildings and two 4-unit buildings. There is also a garage in the rear of the properties. I have attached the dimensions for each building.
Condo unit dimensions, plus garage
Dimensions for the condominium units and garage.
Note as well that there are 4' x 5' flat galvanized metal roofs above each entrance, but they do not require any attention at this time. Repair Assessment FIRST SET The units are past due for a re-roofing. The shingles on the bottom have not been functional for quite some time which has resulted in the roof deck rotting in some areas. The extent of the damage caused by the rot will not be known until we strip the shingles off. The flashing has also become loose, lifting up high enough away from the roofing that rain could easily blow in and damage the interior. I recommend a roof replacement as soon as possible.

  FIFTH SET The last building I assessed has had its roof replaced at some point but it is already showing signs of deterioration beyond repair. There is too much damage (especially on the bottom portion) to begin repairing it efficiently. One of the whirlybirds has lots several of its mounting screws and now the top portion of it is broken. I recommend that the entire roof be replaced in the near future. Materials required for low-slope application:
  • 41 shingles
  • 125 ft. cap
  • 314 ft. starter/drip
  • 18x 44 in. Ice & Water
  • 6x whirlybirds

Client approves the work on August 9 2011, crew begins on August 10 2011: The crew went around the roof and picked out all of the damaged shingles. There were a couple of pin-holed shingles as well. It was found that Ice & Water was used under the roof as underlayment. Everything that the crew removed was replaced. The same procedure was followed for the second complex. The shingles up for removal were sealed together very well, so when we applied more force, entire segments ripped off.

Shingle removal from edges
  When the crew had finished ripping off the shingling on the west side of the sixth unit, we had to waterproof it. It was found that the roof was plank-based, rather than using sheeting. Rotten wood was also found that required replacement (an 8 ft. section). The remaining planks had their nails removed. Once preparation was complete, Ice & Water was applied to the base for waterproofing. The pallets for the east side were delivered later in the afternoon. Weather permitting, we will complete this site tomorrow.

August 12, 2011: With respect to unit 6, we started ripping up shingles while concurrently working on plumbing stack penetrations. The penetrations were tarred and neck tied. Concurrently, re-shingled portions of the roof were waterproofed. There was no more rotten wood found. Our compressor stopped working near the end of cap placement. Hand nailing was our only option. Other than that, the day went as planned.

Waterproofing continued and we began waste removal; the garbage bin had arrived in the morning. The crew is ready to begin roofing in the morning. August 17, 2011: West side shingles were removed today, but we got rained out while trying to take off the flashing from the sidings. Installation of replacement shingles began.

100_1466 August 18, 2011 One of the plumbing stacks came too far out from the roof for the plumbing boot to fit. A crewman was sent back to the shop to get two high dome boots, so we kept putting the PVC pipes in. Two whirlybirds were also cut in and installed. We will complete this site tomorrow around the afternoon.
