Tile Roof Inspection, April 2013, Edmonton

This client reached out to GRS for work on their multi-home building's roof. It is a tile system, with several reports of water ingress and expected damage to the roof itself. GRS sent out a technician to investigate the problems. Unfortunately, photos of the roof taken during inspection are no longer available. The placeholder image above simply provides context to the roofing system style.   Quotation Delivered: April 3, 2013 GRS delivered a quotation to the client covering the services they'd requested. The scope of the work, as outlined in the document, was to remove the tile, check the underlying membrane and valleys, carry out any repairs, then reset the tile system back on top. Before scheduling the work, however, we felt that it would be best to send an inspector out to investigate the problem areas to ensure that the quotation would be fair to both parties in the arrangement.   Inspection: April 22, 2013 The inspection crew went on-site to examine the extent of reported damages. For four of the suites in the building, they checked the roof above and found some major damages that required repair. Near the first suite, there was a major hole in the firewall where both sides of the lead wall's flashing were bent and folded back. The extent of the damage was allowing water to run in behind the flashing and through the hole, spreading down to the suites below as far as the first floor. There was also a piece of wall flashing missing on the front of the turret in the same section, with potential leaks on either side of the chimney in the area. The chimney itself was missing a proper installation and application of ice and water membrane/shield installed around it. Across from these affected areas, on the back of the building, there were several cracked and/or missing tiles in the valley, exposing the roof deck to water and snow that had allowed water ingress to the suite below. In this section of the roof, all of the tiles would need to be removed and the ice and water membrane installed underneath so as to prevent further leaking. Then, with the tiles put back in place, the missing/cracked ones will need to be outright replaced with new ones. Above yet another unit (on the northern corner of the building) there is a long valley that might be overflowing its metal flashing sidewalls and into the attic. Above this valley is a set of short, attaching valleys that separate at 6/12 grade roof from a 4/12; creating a 2/12 grade roof in the middle. On this last 2/12 roof section a great deal of snow could/would pile up during the winter, creating ice dams that allow for a backup of water. These problematic valleys should have the ice shield material on either side of the metal to help keep water in the valley itself. When the crew first attended the site to investigate problem areas and leaks, there were only three that they knew to be coming in. While atop the roof, however, they found that there was no ice and water membrane used alongside any of the roof valleys (not just the ones noted above). Given their absence, it's possible that any and all of the valleys could become future candidates for leaks or further roof damages, especially when any of the surrounding tiles are cracked or otherwise broken/misplaced. The investigative team advised that the roof be cleaned off of leaves and debris, which would allow for a thorough accounting of all of the tiles and the existing system. Rubber-modified sopramastic should be applied to all cracked tiles around the roof to prevent further leakage, and the side cap tiles should be refastened in any places where the nails seem loose or missing.   This post will be updated with roof reports should the client elect to contract GRS to carry out the required work.   CODE: 6703 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Edmonton Residential Roof Drain Repair Service, January 2013

This client in Edmonton requested a quotation as his roof was not draining water properly. He was presented with various options and opted to have three scuppers installed in order to address the drainage issue. This report is mainly comprised of photo journals. Inspection, July 29, 2012: None of the roof vents are caulked and this poses a significant leak risk. There are several inches of ponding water on areas of the roof and blistering is also present. There are gaps on the exterior due to shift in structure. Metal architectural details need maintenance. Materials Required:
  • (3) 6 inch scuppers.
  • 80 ft. 'Metro Brown' RWL.
  • 3 splash pads (3' x 4').
  • Caulking.
  • Zamac pins.

Edmonton EPDM Roof Recovery, July 2012

Below you will find the report for an EPDM re-roofing effort GRS undertook for one of our Edmonton clients. Their existing tar and gravel roof is in need of some work, so we quoted cost for repair, replacement, and recovering services before the client elected to recover the existing roof with EPDM. Our office thought it would be best to establish the scope of the work and inform the customer of what we intended to do at their location. Below is a summary of the correspondence from our team that outlines the project details. Project Scope, July 3, 2012: We will first order the engineered insulation package for the project, and the arrival of this will (in large) determine the effective start date. The best estimate for now is that we can begin late next week (July 11-13), but we promised to keep the client in-the-know if any updates were to come about. The client's on-site contact will be instructed to put a "walk in" bin on street (to allow for us to wheel in wheelbarrows of gravel from the street level); if there are any issues with that he'll let you or I know. We promised to put down sheathing that would safely allow wheelbarrows to be repeatedly rolled across the grass without damaging the property. Another member of the project team will contact the client with respect to colour swatch and choice for metal. They will be advised to keeping the face as low profile as possible, considering the raised elevation view due to sloped insulation raising the parapet. The roofers will be advised that we will be doing an EPDM recovery (removal of gravel first leaving the existing assembly), taking core samples to ensure insulation is dry, and that we are building up parapets to allow for sloped insulation. Finally, the job will require the removal of the flashing around the chimney and possibly require a re-flash (to be evaluated at the appropriate time). Materials:
  • (2) Spud bars.
  • Saws-all.
  • Cordless drill, charger, & extra battery.
  • (2) Push brooms.
  • Trowels.
  • WD-40.
  • (4) High Build 200.
  • (3) Jute mesh.
  • (2) Plastic cement.
  • (6) 6" rolls scrim.
  • (4) 4' rolls scrim.
  • Mastic.
  • Bag of calcium.
  • 5 Gallons of Varsol/Mineral spirits.
  • (2) Rolls duct tape.
Field Report, August 13 2012: The crew met with the two new members, and began working on gravel removal from the roof. First, gravel was shovelled into easily-managed lines on the roof, and was then loaded into the smaller buckets. The buckets were brought to the edge of the roof, lowered to ground level, and put into the wheelbarrow. One member would ferry the gravel into the disposal bin and return for the next load. Once the gravel was removed, existing nail holes in the flashing were filled with caulking to make a watertight seal while the rest of the crew cleaned up the site for the day.

The first store did not have everything necessary, so a detour was made to ensure that the remaining materials were purchased and brought to the client's residence. They began preparing the roof for the day's work when the weather conditions rolled in that would've made the work perilous. The crew left the site for the day. NOTE: The in-progress field reports will be inserted here as content is moved over from the old system. This will cover the EPDM installation, re-sloping, and other site details. - Please accept our apologies for the temporary omission! Field Report, September 11 2012: Today, the crew installed two scupper drains on the south-facing parapet of the roof. This will accommodate for better water drainage and lengthen the life of the newly-installed system. New sheet metal was installed to the parapet, as well as the drop-drain near the garage with a downpipe. photo (38) photo (39)-1 photo (39) photo (40) photo (41) photo (42) photo (43) photo (44) photo (45) photo (46) photo (47) photo (49) photo (50) photo (51) photo (52) photo (53) Field Report, September 12 2012: The GRS team finished up the job, by installing two new caps for the vents, two new caps for the scuppers, and the two downpipes for the scuppers installed the day before.

Apartment Roof Drip Edge in Edmonton

Water Drip and Drainage Support The client reached out to us regarding a four-storey apartment building. They were having trouble with water backtracking behind the gutter and leaking on the ground to cause ice build-up. The first proposed fix was to install a drip edge under the shingle edge and down into the gutter. Furthermore, the joints of the gutters were leaking as well, and the liquid rubber process was explained to the client, who liked the idea of sealing the joints in with seam tape and the rubber solution. There was another section of shingles over the entryway (10 ft x 6 ft) that needed to be replaced. While everything else was being handled, it was requested that an extension be placed into one of the drain spouts. Material:
  • 280 feet of 4x3 inch drip edge (custom bent).
  • Roofing nails.
  • 1 down-pipe extension.
  • 1 to 2 pails of brush grade liquid rubber.
  • 3 – 4 rolls of 4 inch seam tape.
  • 2 bundle of shingles over entrance.
The repairs were carried out without incident, and this work-site has been completed. Below are the photos from our initial assessment:
20150309_121225_resized
Ice buildup was being caused by water backing up behind the gutter and leaking to the ground.

Edmonton Commercial Flat Roof Repairs, February 2012

This client required repairs to their flat roof, and contracted GRS to carry out the service. We arrived for an investigation and were met with a roof report assessment from a year ago - many of the third-party's investigative findings stand true, and gave us an idea of the scope of work to complete. Inquiry Received: November 15, 2011 The client first called in looking for a quote or estimate on repairs that needed to be carried out on their flat roof system. We scheduled them in for a visit a few days later so that we could perform an investigation on areas needing repair. Investigation: November 17, 2011 We sent a technician out to the job site to investigate the client's identified areas for improvement. They presented a report conducted a year ago (via third party), giving the technician an idea of where to examine. Going up to the roof to double-check all of the locations, it seems like the problem areas still need to be addressed. That concluded the investigative stage, and we prepared to deliver a quotation. Quotation Delivered: November 26, 2011 After reviewing the third-party roofing report and undertaking our own investigation to corroborate their findings, we delivered a quote to the client for their consideration. The scope of the work covered the following (referencing scans from the report):
Add granular to cap sheet affected areas.

  Roof Report: February 23, 2012 The team arrived on site to work on the problem areas of the roof. One of the client's employees showed them the roof access hatch and left to continue with their work. The equipment was loaded onto the roof; safety equipment was checked and fully functional. One of the team members got to working on topping up the gum cups (five in total). The other member used their torching trowel to check all of the seams on the upper level. They are in good condition, as is the metal flashing. With that inspection carried out, the team departed the site briefly to procure some materials (storm collar, caulking, etc.). They returned to install the storm collar and seal it with caulking, then moved on to the lower section of the roof. One of the crew cleared the drain of debris, but snow, ice, and water build-up on the lower roof prevented further progress. This site will have to be revisited once the lower roof is dry and the weather is cooperating.

Snow Removal and Roof Replacement in Edmonton AB, 2011

Below you will find a report and quotation for an ongoing commercial client in Edmonton, Alberta from our roofing repair crew. The first is a winter call for snow removal, the second is for a summer call inquiring after a roof replacement. More reports and photos will be posted as they become available Assessment, January 18 2011: Scupper drains on the north and south sides were blocked with ice (frozen drain pipe). I suggested to disconnect the pipe, clean the ice out of the scupper, and clean the snow from the roof. There are a lot of safe areas to throw snow from, so this should be an easy snow removal. Field Report, January 19 2011: We arrived at 8:30 am and removed approximately 6000 sq. ft. of snow from the flat roof. The ice from the two scupper drains was also cleaned and we applied ice melt. When the winter season was finished, the client called us back for a roof replacement quotation. Quotation, July 31 2011:

Industrial Metal Roof Snow and Ice Removal Edmonton, January 2011

Below you will find a series of field reports and correspondence from the Edmonton roofing repair crew responding to a call for snow and ice removal.  Field Report, January 21 2011: In the morning, we broke ice and removed snow from the work-site. After taking a lunch break, there was more than enough left for us to complete the day with. There are only two of us on-site so this may take some time. Client Correspondence, January 22 2011: We appreciate the hard work your crew has been doing despite only have two available. It would be great if you guys could work on getting the parking lot taken care of on that side of the building first as a priority.  Leak Assessment, January 24 2011: We assessed leak issues and determined an ice dam at the gutters and the dam is pushing the gutter away from the roof's edge. It is unsafe to move ice and snow without the entire gutter or ice falling on pedestrians or vehicles below (an entrance way is right below the problem area).

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.

Next, the ventilation units were addressed.
