Article: Flat roof repair Edmonton emergency repairs on a commercial storage building in Edmonton Alberta.The following roof report is of an emergency roofing repair call we received during a rainstorm here in Edmonton, Alberta. The customer wanted us to come to his place of business and repair the leaks that were occurring. Monday June 22, 2015 Crew arrives at 14630 128 Avenue, Edmonton to complete repairs. I got a call from this customer at our regular customer location. He is the new head of maintenance on site. He was saying they have a leak on the west wall of the building, in the center. Upon inspection I found numerous rips in the roof along with the membrane completely separated from the drain.
There were two different scopes of work we had to complete to stop all the leaks.
They are as follows:
Gum patches to 3 or more areas.
For this repair we had to use mastic and reinforcement mesh to seal up leaks. This consisted of putting one layer of mastic on the affected area, followed by reinforcement mesh on top of the mastic. We then added one more layer of mastic to seal in the mesh.
Replace the roof drain with new drain "3 inch" and roof the drain in using SBS 2 ply torch-on system.
For this scope we had to rip out the old drain. and install a new one. Once the new drain was installed. We had to roof it in using a 2 ply SBS system. for this we laid out the base and torched it to the deck of the roof. We then installed the cap layer to the base layer.
Man hours to complete: 20.
Materials needed: 5 ft of cap. 5 ft of base. 1 can of spray primer. 1-3 inch drain. 1 can of mastic. 1 roll of 6 inch reinforcement mesh.Article Topics: Edmonton Roof Repair, Flat Roof, Emergency Repair CONTACT US Call our 24 Hour Emergency Roof Repair at 1.780.424.7663.

Article: Flat Roof Repair Edmonton, Alberta. Tar and Gravel. Commercial.
Inspection and repair of commercial tar and gravel flat roof repair in Edmonton, Alberta. Repairs include a rooftop vent, a B vent stack, make-up air unit curb, and a split in the tar membrane.
Flat roof repairs are required on every commercial and residential low slope roof - that is an unfortunate reality. However, repair costs can be mitigated through regular preventative maintenance.
Visit our main website for a flat roof maintenance checklist.
Tar and gravel flat roofing is a type of low slope roof that can be repaired almost indefinitely if regular maintenance is done to the roof.
We recommend that inspections should be done every spring and fall. In spring to ensure that the winter cold hasn't caused damage that needs to be repaired before spring rain showers and in the fall to ensure the roof is in water-tight condition for winter months.
Performing regular maintenance inspections and doing any repairs required (in a preventative manner) will lessen the cost of repairs, damage to the interior of the building, and this will also extend the life of a tar and gravel roof at least 50% (if not more).
The report below includes a split in the tar membrane and other minor repairs which could have been avoided (or at least mitigated) through regular maintenance.
May 9, 2015: Customer Calls in to Call Center.
This customer works for a large commercial property management company in Edmonton. She has come to rely on our emergency roof repair dispatch quite regularly.
In this instance she had a tenant moving in to a strip mall location. The tenant was doing leasehold improvements on the interior at the time of the leaks. So needless to say, the tenant wasn't impressed.

Roof Type: Tar and Gravel Flat Roof
Location Type: Commercial Strip Mall
Emergency dispatch. Our customer was experiencing a leak that was terminating on the ceiling inside directly below a make-up air unit. The scope was to find any source of the leak and repair it. I found four spots of concern for repair and regular maintenance.
Roof Repair # 1.
The first repair to be done was around a B-vent that was starting to lift from the base of the flange where it ties into the roof. I spudded the BUR membrane around the B-vent and installed a roof gum patch on it using mastic and mesh.
Roof Repair # 2.
The second repair was the make-up air unit itself. I located a previous gum patch 1 foot around the unit. I spudded the old gum patch out and also went another 1 foot beyond that to ensure a good seal. I gummed up on to the metal and meshed out 2 feet from metal on to roof and them sealed with mastic.
Roof repair # 3.
The third repair was a deleted vent that I didn't see anything wrong with it but it was close to where leak was so just to be sure I fixed it with mastic and mesh. I spudded out the area and put one coat of mastic then used mesh to seal the vent to the roof then one more coat of mastic.
Roof repair #4.
The fourth leak area was a seam that was starting to split and the seam was running into the make up air unit where the leak was located below on the ceiling of the location. I spudded it all the way up 11 feet total then used mastic and mesh to seal it in.
Man hours to complete = 4.5 hours x 3 men for a total of 13.5 hours.
Material used: 2 cans of mastic. 1 roll of 6 inch mesh.

We arrived on-site at 7:20 am to find the problems with the roof. The building management representative had reported leaks and our emergency response techs were in attendance the night before.We performed our daily site safety procedures (including tool-box meeting, site hazard, and fall plan).Once we were on the roof we saw that the old patch previous roofers had applied was splitting at the curb and we found a couple of other spots that had loose laps.We repaired the leak areas as required and photos are included below.
- Engineered liquid rubber roof coating: 2-ply coat to complete roof, fastener replacement as required, sheet metal repair as required to achieve a water-tight state.
This product is the first product we have had as roofers that solves metal roof issues and has been extremely successful with considerable and complicated roof systems for a number of our Fortune 500 or multi-national clients.June 13 2012: We stopped by the shop en route to pick up a trowel, caulking, and wet dry gum (plastic cement) in case the leak was able to be fixed immediately upon inspection. On-site, the client lead us to the leak site where tiles were becoming stained. Visible sagging was noted. After removing the stained ceiling tile, it appeared that the leak was coming in around the RTU unit directly above someone's desk in the southwest corner of the top floor. Upon roof inspection, it was clear to me that the problem area was the plumbing vent in-between the exhaust fan and the RTU unit. It had previously been patched with plastic cement as a temporary solution. There are also a few other areas which could potentially leak in the future; a few gas line penetrations, gum cups around guy wire penetrations for antennae on the roof, and a few flashing issues around exhaust fans.
