Residential EPDM Roof Replacement, October 2015, Edmonton

This client's home bears a low-slope roof that they wished for GRS to replace with an EPDM system. The crew of technicians went out to their location and completed the roof replacement in two days' work.   Materials List: October 13, 2015 Two technicians went out to the client's location and inspected the roof for what kind of deficiencies might be encountered during the roof replacement. During their inspection, they noted down the expected materials that would be required for the job.
  • 2x Rolls of EPDM
  • 7x Pails of EPDM bonding adhesive
  • 1x Pail of primer
  • 1x 6" roll of form flash
  • 2x Pipe boots
  • (84) 4' x 4' sheets of fiber board
  • 4x Roller cages and sleeves
  • 1x Box of seam tape
  Roof Report: October 16, 2015 The team arrived on site for 8:00am, and had their disposal bin arrive by 9:00. At that point, they were already underway ripping off the old roofing system and making good progress. It was after then that they found that there was no plywood with the order, just 2x6 boards. They departed to get the requisite plywood, and returned an hour later around noon. The boards were all mechanically fastened into place, with some of the EPDM laid atop it. The crew departed in the early evening, set to return the following day and focus on the remaining EPDM and metal flashing.

We removed the existing EPDM system until the plywood was exposed. Many of the boards were either rotting or had holes in them.

Rotted wood that had eventually given way, creating a prominent hole in the assembly.

After installing new fiber boards over the assembly, we applied bonding adhesive to the underside of the EPDM.
    Roof Report: October 18 The reporting technicians notes were brief, but the site is now marked complete with the EPDM and flashing that was left over from the previous day's work. Everything went well and the roof was covered without any issue or hindrance of note.

Nisku Liquid Rubber Roof Recovery, August 2011

The report below follows services carried out on a metal roof for one of our industrial clients. They sought GRS' assistance in recovering their roof with engineered liquid rubber, with some other spot repairs to complete as needed. Inspection: June 2, 2011 The GRS crew went on location to inspect the existing roof system and take photos that will help the project management group form a better idea of what service will be needed at this location. The photos appear below.
100_0006
Our client had an industrial-grade metal roof. A crew was dispatched to perform an initial inspection with regard to the scope and requirements of performing a roof recovery using engineered liquid rubber.
100_0008
Many of the screws were exposed or missing, with parts of the metal beginning to rust.
100_0009
Rusting at the seams, with exposed screws running the length of this section of the roof.
100_0010
There were signs of previous spot repairs. In this case, caulking had been applied to the screws.
100_0011
More spot repairs, with caulking applied at the seams and over the edges. This solution had expired, with cracks forming along the length of the roof where the caulking had been applied over the seams.
100_0012
Closeup of some old sealant applied over seams and around raised screws. Note the hole in the fastener that had previously been closed off. As well, there are slight buckles in the metal. Each of these deficiencies contribute to common leak entry points and a loss of a metal roof's water shedding properties.
100_0013
We inspected the wall connection, noting whether any components on the wall itself needed to be replaced, and whether we had to order any new flashing as part of the recovery.
100_0016
Sealant had previously been applied to the window sills, flashing, along the wall seams, as well as on the intersection between the flashing and the standing seams on the roof. Besides showing signs of cracking, there was also more rusting along the walls.
100_0017
Significant rusting on the flashing, with an unsealed base for the rooftop appliance. As well, the edging over the window sills is not flush with each segment. Further down, it can be seen to be curling up from the window.
  Quotation Delivered: June 6, 2011 After seeing the roofers' investigation photos and measurements, GRS' project management could deliver an accurate quotation for services to be carried out of the roof. Included in the quotation were two separate services; the engineered liquid rubber application and an EPDM installation for the area around two eaves. Also attached to the quotation were the documents and web links surrounding GRS' workmanship guarantee, system methods, schedule availability for the season, and more. There was another note mentioned that regarding schedule availability, it's best to book liquid rubber jobs earlier in the season for when it's warmer. Even though the solution will bond, it performs best when applied in warmer weather.   Roof Report: July 20, 2011 The crew went out to the client's building and got to administering trowel-grade liquid rubber to all penetrations, joints, and problematic areas that has been previously discovered. They also did a lap around the perimeter, ensuring watertightness on the high-risk parts of the roof. They then set up the pump to apply the spray-on liquid rubber and managed to cover roughly one-quarter of the roof itself. Their plan was to finish the entirety of the roof the following day, so they packed up the equipment, cleaned the site, and closed the site for the evening.

By the end of the day, our technicians managed to coat one-quarter of the entire roof.
    Site Inspection: August 1, 2011   One of the senior members of GRS' crew went on-site to inspect the liquid rubber application and found it to be forming a good seal. There was some water that had formed a small bubble in the rubber, but once popped it was deemed fit for continued use as the rubber still formed a solid barrier to the metal.   Roof Report: November 25, 2011 Several months after the initial liquid rubber coating, the client call in to report some other leaks in separate areas of the roof. GRS sent a team out to the site to investigate and carry out the necessary repairs. They administered sealant to the flashing where the wall meets the north-facing roof edge, and again on the south-west corner of the building. They also sealed in the wall-to-roof spots on the west-facing wall and inspected the existing wall spray. After carrying out the spot repairs, they had a better idea of what else needed to be done to the roofing system, and returned the following report:
  • The west-facing wall where the windows are is 3' x 78'. Will need 100' x 6" skrim sheet, and roughly 16 man-hours to install it.
  • The north-facing wall is 3' x 40'. Need 50' x 6" skrim sheet for another 12 man-hours to install.
  • The west-facing wall's upper roof is 3' x 24'. Need 25'x6" skrim sheet and 10 man-hours to finish.
The site was cleaned up, and the crew departed, leaving the repair options in the hands of the client.   This report will be updated as more reports come in, should the client elect to move forward with repairs.

Edmonton Tar and Gravel Roof Repair

A prospective client north of Edmonton reached out to GRS to address a flat, gravel roof that was found to leak during the warmer period of this past winter. The water would drip into the unit and out of the ceiling in an approximately 6' x 8' area. They requested an estimator to come examine the roof and provide a quote for repair or replacement. Researching the building and gathering pertinent dimension information, GRS delivered estimates for a variety of roofing replacement systems in addition to what the expected repair would require. Client evaluated the options and believed the EPDM roof recovery to be their best option, rather than repair smaller portions of the roof. Appreciating the quote and evaluation, the client elected to put the project on hold for the time being. Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

High River SBS Roof Replacement, October 2014

This commercial client required a roof replacement and elected to have GRS install a 2-ply SBS Modified Bitumen system. This was done in High River, AB, far to the north of the province.   Roof Report: October 24, 2014 The team arrived on site for 9am and began to get it prepared to commence work the following day. Material lists were organized and ready for purchase, and the tools were loaded onto the roof. The crew waited for the dump bin to arrive, and once it had they went off to the store to pick up the last of the materials needed for the job's beginning. They ended the day for 3:00pm, leaving the job site for the evening.   Roof Report: October 26, 2011 The four team members arrived for 8:00am and worked for a few short hours until 11:30. In their time on site, they stripped off the torch-on system and moved materials to the side of the roof where they would begin work the following day. The weather forecast called for heavy snow, and ice crystals were building on the roof even after torching. They called it for the day at 11:30am, and would return the following morning.   Roof Report: October 29, 2015 Starting the morning at 7:30, the team got to work with chipping away ice, blow-drying the roof, and cleaning it off for work. Once done, they got to stripping outer walls, putting up around 25' of fascia, and stripping the parapet walls too. They installed two high domes and starting putting more capping on. Heavy snowfall came in just before 5:00pm, so the team wrapped up the site for the day.   Updated Quotation Delivered: October 30, 2014 We sent over an updated quote to the client to show payments that had been applied to date. There was some uncertainty remaining about the amount of sheathing requiring replacement, so the final quote was yet to be confirmed.   Roof Report: October 30, 2014 This day saw a lot of ice chipped away and snow swept off of the roof. They team torched the capping and installed scupper drains and the necessary downpipes. They left the job site for 4:00pm once word arrived that some more of the materials for the job site on order had arrived. They got the materials and returned to the town; an 8-hour round trip. Roof Report: October 31, 2014 There was some light rain in the morning, but not enough to cancel the day's progress. The rest of the roof system was ripped off and the rotten plywood underneath replaced. The last scupper drain was installed, and some more of the parapet wall was stripped. Once done, the last of the capping was torched on and materials were moved and prepared for the next day. After clean-up, the team departed the site for around 5:30pm. The day's efforts saw 25 sheets of OSB plywood 7/16 installed, which allowed for a final quote to be delivered to the client as everything that would be exposed and inspected had been so. High Level-20141031-03223 High Level-20141025-03127       Roof Report: November 2, 2014 This day, the team met on the roof for 8:00am and got to work. Their task for the day was working on getting the enco new paper was completed, and the job site was cleaned up afterwards. They left the site at 1:00pm, another job completed.     CODE: 10006 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663. Mail to: 3428 99 Street NW Edmonton, Alberta T6E-5X5.

Sherwood Park Commercial Roof Resurfacing, July and August 2014

Below is a series of field reports for repairs done to a commercial property by the Edmonton roofing repair crew. Our initial assessment showed that the roof was an ideal candidate for a complete replacement due to the large scale of repairs which were quoted.  Scope of Work:
  • Complete roof resurfacing including:
    • Gravel removal.
    • Spudding.
    • Cleaning.
    • Membrane resurfacing.
  • Two coats of liquid rubber.
  • Removal of all obsolete pitched pockets, with the extension of the current active pockets to a minimum of 6 in.
  • Fabrication of custom sheet metal grease trays
Field Report, July 7 2014: After completing a pre-install meeting with the customer, we took measurements for the pitch pockets, grease trays, and pitch pocket caps. We then went to the shop for a material requisition and they advised us our order would be ready for tomorrow afternoon. Our crew delivered the scope of work as promised over the next few weeks. As we had anticipated, this series of spot repairs was only temporary and it was only a matter of time until our client called us back. Ideally, we would like to see this particular site undergo a complete replacement since the structure's sustainability is running out and will only require more repairs as time goes by.
Field Report, August 5 2014:
Today we installed a full length safety railing along the eaves of the roof. We began by loading 11 patio stones and high density foam to the roof. We then installed the walkway and took our client on a tour of the completed work. He was pleased with the repairs.
