Edmonton Residential Leak Repair, November 2010

This client reported a leak around their chimney and contracted GRS to carry out the necessary repairs. The service was done quickly, and the leak issue resolved. Inspection: October 21, 2010 The technician carrying out the investigation on-site found that there is a leak coming in on an inside wall up near the vaulted ceiling. They took photos of the roof and possible fault sites to help give the repair crew a better idea of where to make the necessary repairs.
Picture1
Our inspection of the gutter system and eaves-trough revealed crumpled metal and improperly fastened components throughout the assembly.
Picture2
Next, we moved onto the shingle roof. Our technicians looked for signs of weather damage, missing or broken shingles, and any holes or tears in the roof surface.
Picture3
Next, we moved onto the ventilation units. Signs to look out for include holes or dents on the unit itself, crumpling around the base, and unsealed seams.
Picture4
We found that some of the step flashing at the wall connections was not sealed properly, or the caulking was wearing out.
Picture6
The downspout only extended a quarter way to the gutters. Although some water was draining, there was a significant amount of moisture that had seeped through the shingles and into the building on the way down.
  Roof Report: November 15, 2010 The roofing crew arrived on site and, with the assistance from the previous report, found the leak and made quick work of the repair.

Roof Retrofitting in Unity SK, August to October 2010

Below you will find a series of Roof Reports and photos from our roofing repair crew in Unity, Saskatchewan. The client asked us to perform some retrofitting and approved some assessments that were made on-site. Roof retrofitting and leak mitigation was provided.

Roof Report, August 24 2010:

We opened one ventilation unit which was found to have traces of moisture. It was water-tested, which came back positive as a leak area. We also found areas that had open wire penetrations and gas lines going into the building. A cut-test was also performed, where 4-ply styrofoam insulation (5") and a vapour barrier was found. This might explain why water had to travel some distance before it appeared as a leak, since the rest of the roof is in good shape. Areas requiring maintenance were sealed with mash, mastic and additional caulking as required. Client Callback, October 21 2010: After TPO recovery, the client found more water leaking at grade-level. We resolved the issue with caulking around the problem area. < End Report > Code: 120 Contact Us Call our 24 Hour Emergency Roof Repair at 1.780.424.7663.

  1. Site Visit Done. Initial Assessment Completed. Photos on file (see Krain Consulting report).
  2. Options for roof replacement, roof overlay, repairs, and regular maintenance attached.
    1. Full roof replacement is not required except at garage portion where the installation crew will determine how much to take out when they open roofing system.
    2. An EPDM, TPO, or PVC roofing system overlay is a reasonable option for this roof.
    3. A roof overlay saves significant costs, provides environmental relief as old system does not end up in the waste, and all the roof overlay systems are very successful.
    4. The deciding factor when considering a roof overlay is whether the preference is a black roof (drawing the sun in) or a white roof (a cool roof for more efficient function).
    5. Repairs to existing roof is a consideration, but not recommended considering the number of failures.
  3. Roof Flashing.
    1. The existing roof flashing is in moderately good shape. It could be replaced but it is most definitely not required. We suggest keeping as much of the old flashing as possible.
    2. We suggest keeping as much of the old flashing in place as possible. When the new roofing system is retrofitted, the Senior Installation Manager would instruct the crew to save as much of the old flashing as possible (unless client decides to simply replace all flashings).
    3. The roof flashing invoicing (whether all new is ordered or the existing flashing is modified) would be a separate invoice. Our sheet metal / flashing crew is about two weeks behind our flat roof membrane applicators so we would bill the flashing separate of the roofing system.
  4. Eaves, Downs, and Scuppers.
    1. Crew to be instructed to slope roof in such a way that the flow of water moves toward the east and south.
    2. Custom fabricated architecturally designed eaves and gutters with external scuppers (drainage to gutter area) will be added to back of home and east side. Client and installation manager to determine where the downspouts will send water to on east side of property.
5. Perform regular maintenance once or twice per year thereafter.

Photo Gallery: Edmonton Rooftop Deck, September 2010

This report serves to show the before-and-after difference that a rooftop patio reconstruction can make. There are no in-progress reports to cover; just a photo gallery to highlight the expertise that GRS can bring to your household upgrades.  
001
After removing the original roof membrane and step flashing from the perimeter of the patio, we applied new roof boards to the surface.
002
This custom fit section is where we would later install a drain. We ensured that the piping was in full repair and that the surrounding roof surface had no deficiencies.
004
Once the boards were installed, we began laying EPDM over the roof.
 
005
EPDM was secured against the wall connections using termination bars around the perimeter. This contributed to the watertightness we were aiming for.
006
Completed drain installation.
008

Edmonton Flat BUR Roof Repair and Maintenance, September 2010

This Edmonton client required repairs to an existing built up roof system. Some areas on the roof appear to be blistering and others have ponding water. A crew was dispatched to perform the repairs once the weather was suitable. Note: This report contains several separate repairs and maintenance reports completed at different times.
Scope of Work: Repairs to Existing BUR – Built Up Roof System.
  • 7 areas of the roof have blistering that requires repair.
  • 3 areas of the roof have ponding that requires repair.
  • 2 units show water penetration to the interior.
001
Some blistering in the roof around ventilation vents, with signs of moisture buildup.
002
Exposed blistering sticking through the gravel layer.
003
Holes in the base of a plumbing vent. During periods of precipitation, water has a direct point of entry into the building through holes such as these.
004
Significant signs of moisture buildup lead from evaporated standing water.
005
We removed the gravel around sections of significant moisture buildup to expose the roof surface. We found small pockets of waterpooling, which was also entering the building through the various blisters and tears that were identified.
008
Spudding over some tears.
007
Parts of the underlay that bordered with the edge of the shingle roof section were curling up, and required refastening. Moisture was entering the building through here.
010
Cement was applied over the sections of the roof where we had found significant standing water.
013
For smaller holes and blistering, we applied spudding, mesh over top, and then followed up with a second layer of spud.
  Roof Report, January 28, 2011: Investigated roof leak, approximately 18" frozen snow on roof. Checked all repairs done previously and no deficiencies could be found. Possible leak area (small leak now, did not show for 6 months) could only be related to metal flashing/roof flashing interface, which right now is frozen together.
I told our site contact that as soon as we have a good break in the weather we would be back to source the leak. She also asked me to check how the drains were, which were exposed and working fine. The client then showed me interior cracks in her ceiling, which with the amount of snow on the roof are more than likely due to extra weight on roof.  She told me their condo board has no money to pay for snow removal and they would take care of it themselves.
Annual Maintenance Follow-up, April 25, 2012: Arriving on site we walked around the building to look for any signs of potential problems ie. open mortar joints and general degradation, and nothing stood out. As we entered the premises interior ceilings and walls did not show any signs of water damage/problems.  Once we proceeded to the roof there was nothing that stood out. Closer examination showed some caulking drying up and cracking. We proceeded to caulk all units/protrusion on the roof and also caulked all seams and screws on the parapet flashing. There were a few minor repairs needed near the scuppers. We used MS Detail to do these repairs. Otherwise the BUR portion of the roof showed no signs of any deficiencies, such as blistering or ridging etc. Once the body of the roof was inspected for these deficiencies we then proceeded to broom the entire roof.  We would level out gravel where the wind around some units would push the rocks away and create a bare spot which would be open to exposure/ UV rays. Then we leveled out the gravel on the entire roof looking for low spot and making sure they were covered. There are only two areas of concern.  The first is the shingles under the scuppers; they are badly worn and are in need of replacement. The second is the gyp rock cover the hatch door. It came off when we opened the hatch, we would have fixed it but it had been re-screwed back on so many times that the edges of the gyp rock were nothing but torn paper. There were several different types of nails and screws around the edge to further indicate it was repaired many times. Roof Report, June 20, 2012:
Removed 18 inches of gravel around vent. The plys are wet and soft so we applied 12" of plastic cement around.
IMAG0271
The ply around the vents were wet, soft, and coming apart.
IMAG0273
12" of plastic cement was applied around the base.
Annual Maintenance Follow-up, January 30, 2014:
An email sent from our project manager to the client:
Hi, Our report, that was copied to you, determined that there are a number of areas of concern that will cause leaks; 1. Areas such as the caulking on the heat stacks (you don't need to call anyone to replace heat stacks) - maintenance issue. 2. Ice damming glacier effect - again maintenance. The previous repairs are not the issue. You have a failed roof that is going to fail in a number of areas at any time, as with this report. When the roof fails the leaks will manifest on the inside at the lowest points, the same points as always because water finds the lowest point in that area and manifests. Did you want a work order to have repairs done? Thanks
20140128_151001
Some of the rooftop appliances, such as the base of this heat stack, required re-caulking around its seams.
20140128_151237
Some of the rooftop units also had some tears along the termination bar which required resealing.
20140128_151456
Exposed pocket adjacent to a piece of edge flashing. When ice damming melts, the water has a clear point of entry into the building through sections such as this.
20140128_151422
Ice buildup directly facing an exposed section of the roof edge. We advised the client that without certain parts of the assembly being replaced, water would eventually leak into the building once the snow and ice melted.
 
 This project may be updated at a later date.

Flat Roof Drain Installation and Repair, Edmonton, 2010-2011

This client sought GRS' assistance in alleviating leak and ponding problems on their tar and gravel roof. The first visit made out to their location had us install a new drain, and the second visit (the following year) had several vents and roof penetrations re-sealed to stave off water ingress.   Quotation Delivered: September 10, 2010 The GRS Project Manager sent over the quotation that the client requested, covering the roof drain installation and surrounding area patch. The job itself was scheduled to be a quick install, to be completed on a single visit to the site sometime during the following week as time provided. Roof Report: September 16, 2010 The GRS technicians arrived on site for 11:30am and met with the client regarding the roof drain and low spot that required attention. Once they'd assessed the site, it was decided that the repair would proceed on this day so the pair drove to the local shop to pick up the necessary supplies and materials. They returned an hour later and went up to the roof, beginning the repair on the drain. The job itself only took two hours, so they departed at 4:30pm for the day.

The drain repair entailed applying a new liquid rubber patch over the deficient sections. We found some holes in the membrane surrounding the drain itself, as well as old sealant which was cracking.

Next, we moved some gravel to exposed sections of the roof which we suspected were leak entry points. We found some minor tears and holes in the membrane and spudded over them.
13015 117 ave nw,edmonton 003
After affixing the drain back into place, we put a mesh over the coatings and then sprayed primer around the drain.
Quotation Request & Delivery: June 20, 2011 GRS received another phone call from this client about a leak coming through the roof. This time, they sought the replacement of two plumbing vents and two gooseneck vents. As the current roof is tar and gravel, the repairs can be done with a torch-on system. We sent over the quotation for the work to be completed and scheduled them in with the roofing crews.. Roof Report: July 29, 2011 The crew returned to the client's site an hour after a heavy storm had subsided. They spent a little bit under an hour and a half on-site before getting rained out once again. Regrettably, they were unable to fix the root problem and would have to return when next possible. Roof Report: August 7, 2011 After the previous week's delays, the pair of technicians arrived on location for 7:00am, completing the safety documents and beginning the day's preparations for torch-on repairs. They picked up some more supplies once the store opened, and got to torching on the repair patches at 10:20am. By the time 12:30pm rolled around, the repairs were completed and the team had to remain on fire watch duty for the prescribed hour before the site could be safely departed. Without any issues presenting themselves, the crew packed up the site and left the job site a completed project.  
DSCF0167
There was significant standing water around this cluster of rooftop appliances. The client wanted their vents replaced, although we recommended replacing a section using torch-on.
DSCF0168
Our first step was to drain the water around each of the appliances.
DSCF0169
We began by torching down some rubber around the plumbing boots, and then applying coatings over the seams.
DSCF0171
The process was repeated for all appliances along the roof edge.
DSCF0172
Next, the ventilation units were addressed.
DSCF0173
The main cluster of appliances where we found the standing water required custom strippings fit around them before they were torched down.

Lloydminster Roof Slippage Repairs and Standard Maintenance, August 9 2010

Below you will find a report from the Lloydminster roof repair crew. The client requested a routine maintenance for water leakage and replacement of weathered roof components.  The sloped roof area (measuring 31’x29′) is showing major BUR slippage. Section replacement should be attended to as a short term solution. I repaired the top edge of the sloped roof area with mesh and SOPRAMASTIC, which were deficient due to the aforementioned slippage. As well, note that the asphalt layer was separated from the metal edge detail on the roof (I did not use primer for this).
Separated layers

The remainder of pending issues were corrected with caulking and cleaning the drain system, which was very clogged. I attributed some portion of the leak to this, which may have been resulting in residual pooling.
