EPDM Roof Restoration with Liquid Rubber Coatings, September 2015, Edmonton

GRS first carried out an inspection and some light repairs on this commercial building's EPDM roof in April of 2012. There are two roofs in this system, one EPDM and one metal. We began working on the roof in September of 2015, proceeding with an engineered liquid rubber coating, on top of repairing any new fault areas that have developed since then. Check out this page for the original inspection information, though it may be referenced in some sections below.

Scope of Work
Roof Reports [all 2015]
  Inspection: April 17, 2012 The original inspection is very thorough and worth reviewing. In summary, the EPDM and metal roof was suffering from some puncture holes, leaks, and membrane degradation. The structure itself is sound, but could use some maintenance to address then-current and future problems. Spot repairs could be carried out, or the roof could be recovered with a new watertight system (ie: liquid rubber).   Scope of Work: September 7, 2015 The crew made a list of things to present to the client, covering all of the pertinent safety information and everything needed to demonstrate that the scope of the project has been thoroughly considered. Below is a copy of everything they were prepared to cover.
Required on site to show HSE Manager:
  • GRS tool box documents
  • MSDS (attached)
  • WHIMIS tickets.
  • First aider with ticket
  • Fall arrest tickets
  • First aid kit
  • Pylons and caution tape for 6' control zone
  • Harnesses and ropes
  • Proper safety glasses
  • Steel toe boats (with green triangle symbol)
  • Long sleeve shirts
  • Gloves
 
Other:
  • Liquid rubber - 15 - 17 pails
  • Rollers, sleeves, brushes
  • Seam tape
  • Flashing mesh
  • Pressure washer, hose, electrical - be sure to advise office staff that roof may leak while washing.
  • Rags (materials to dry roof)
  • EPDM repair materials and tools
 
Notes:
  • Access to roof is with roof door - walk out on roof. Do not use ladders to access roof.
  Scope of Work:   Roof 1. EPDM ballast roof restoration. Approximately 36' x 50'
  • Remove rock ballast from half of EPDM roof
  • Wash EPDM roof membrane to white-glove clean
  • Repair EPDM as required
  • Coat half roof with liquid rubber (about 900 sq feet or 3 - 5 pails)
  • Return ballast to EPDM roof
  • Remove rock ballast from other half of EPDM roof
  • Wash EPDM roof membrane to white-glove clean
  • Repair EPDM as required
  • Coat half roof with liquid rubber (about 900 sq feet or 3 - 5 pails)
  • Return ballast to EPDM roof
  Roof 2. Metal Roof Coating. Approximately 56' x 50' Details first. Wash roof and/or internal gutters as required. Dry. Reinforce all your details with liquid rubber and/or seam tape or mesh as required before rolling out or spraying liquid rubber. Check all fasteners and replace as required or coat with liquid rubber. Check all rooftop penetrations, flashing, roof-to-wall connections, roof eave to gutter area, internal gutters and sheet metal connections, internal gutter to wall connections, and seams (especially horizontal) that may be separating. Clear old caulking etc. Add seam tape or mesh with liquid rubber. Coat complete metal roof, in gutters, and up parapet walls 30" in liquid rubber. Be sure to tape off a clean line at wall at a height of 30" or so - the line needs to be clean and straight. Pay close attention to internal gutters especially where sheet metal connects and where the internal gutter is at a vertical meeting the metal roof edge (that's where most leaks on these systems occur).

  Roof Report: September 8, 2015 The team met in the morning for a brief safety meeting with the entire crew present. They then went up to the roof to begin moving the ballast from the west side onto the east side, preparing the area for cleaning. Using pressure washers to clean off the surface, the team found some difficulty with the amount of clay mixed in with the dirt. They sent one of the technicians out to pick up more scrub pads that could handle the tougher soil. Heavy rain began rolling in, so the team had to depart a little bit early. Half of the roof is cleaned off and prepared for the following day's application of liquid rubber. Plan for September 9: Arrive for 7:00am, and put down the first layer of liquid rubber on the now-complete half of the roof. While it cures, the second half of the roof will be prepared for the same.

Scrub pads were used to remove the remaining soil. After the roof was dirt-free, we gave it a final wash.
20150908_150404
We had to shut the site down when heavy rain began to roll in. Half of the roof was cleared and now prepared for liquid rubber applications.
    Roof Report: September 9, 2015 The GRS crew arrived on site for 6:45am, and had their toolbox meeting for fifteen minutes until the client arrived to grant access to the roof. They began by clearing off the residual moisture and prepared to apply the liquid rubber to half of the EPDM roof. In the meanwhile, the other part of the team was at the shop picking up another six buckets of the liquid rubber solution. By the time they'd returned, the first team kept cleaning the metal roof. Half of the metal roof had liquid rubber applied to it, and the technicians kept preparing the gutter and sidewalls for recovery. Once the west side of the EPDM roof had cured, the crew moved the ballast back from the east side. They kept preparing and cleaning the east side for tomorrow's application of liquid rubber, as some rainfall prevented them from more liquid rubber application. Both the EPDM and metal roofs have been half-completed with liquid rubber, with the other half prepared for the following day's work. The customer also reported a heavy leak, which was traced and temporarily patched until it can be addressed at-length.

  Roof Report: September 10, 2015 Work began on the roof around 6:45am, where the team got to cleaning the EPDM roof in preparation for more liquid rubber. Everything was cleaned and prepared for 10:00am, and after a brief coffee break one technician got to applying the rubber solution to the ribs of the metal roof while another applied it to the EPDM. The two remaining crew mates finished up the mesh and detail work on the metal roof, working through 12:30pm until lunch. Resuming at 1:00, they all continued with their assigned tasks until the metal roof was done around 3:00pm. The EPDM roof has a 5' x 36' section still requiring ballast removal, cleaning, and liquid rubber application. It's expected that the work will be finished tomorrow.
20150910_081808
After clearing the ballast rocks from the other half of the EPDM roof, we again had to wash off the clay/dirt mixtures from the surface.
20150910_101401
After washing the detritus, the surface was nearly ready for liquid rubber coatings. Scrub pads were used to remove any remaining buildups. One 5' x 36' section of ballast was still remaining, as well.
20150910_101450
Concurrently, another technician applied coatings to the remaining metal roof's ribs.

    Roof Report: September 11, 2015 The crew arrived on site for 7:30am, and got to cleaning the remaining section of the EPDM roof. By the time they took a break around 10:10am the roof was clean and ready for the liquid rubber. They performed a leak test on the second roof, and made sure that there was no water ingress to the offices below. Once confirmed, they prepared the breather holes on the metal roof's ribbing with mesh and rubber. Lunch break went from 11:30 - 12:00pm, and the EPDM roof was finished shortly after. The rubber has to cure before the ballast can be replaced, so the team moved on to the metal roof to continue adhering the mesh and rubber to the ribbing. Come 2:40pm, they had the site cleaned up and marked the job complete. < End Report >   CODE: 6621 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Photo Journal: TPO Flat Roof Recovery and Sloped Insulation in High Level, AB

Below you will find a photo journal from a commercial contract in High Level, Alberta. The work entailed a TPO flat roof recovery and sloped insulation. Background When a roof reaches the end of its life, our clients are faced with the choice of either a full replacement or a recovery. Roof recovery refers to applying a new system over an existing one when the roof is reaching its end-of-life (1). Depending on climate conditions, preference, or preexisting solutions, a roof recovery may be performed using TPO, EPDM, bitumen, cap-sheets and/or asphalt. Sloped insulation refers to the tapering that exists on an insulation system. As a weatherproofing measure, when precipitation reaches your roof, it will run off into the drain system down the slope. Call us today for a consult on which roof recovery system is right for your commercial, industrial, or residential environment. < End Journal > Code: HIGH Article Topics: TPO Flat Roof High Level Alberta.

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.

    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.

Commercial Roof Recovery for Existing Client in Edmonton AB, April to June 2015

Below you will find a series of quotations for an existing commercial client. We had previously dealt with some leaks for them as outlined here. This time, the client required a roof recovery for a 28 ft. x 44 ft. garage. Client files request, April 20 2015:
I know that you quoted on the small garage, we would like another quote that requires the following: layout, retrofit, TPO roof, no asphalt.
Quotation, April 20 2015:
  • Layover, remove stone.
  • Install new 2 in. polyisocyanurate and 0.45 mm TPO membrane.
  • New flashing is required all around to match the front of the building.
Assessment, June 22 2015: We arrived at 8:00 am and searched for roof leaks around the unit for two hours. With no luck, there was still the remaining task of installing the last drain unit over another one of the units which needed work. The roof on the second building is a 28 ft. x 44 ft. BUR roof on a wood deck that leaks in too many places to fix. One drain on the northwest corner and three other penetrations, as well as two vents and a motor exhaust are going through the roof. There is a 4 in. wood detail around the edge and one scupper. We suggest an EPDM roof recovery. The maintenance manager for the site also gave us a call to tell us that a leak was found on the west wall of the building. The crew found numerous rips in the roof along the membrane; it had been completely separated from the drain.

Materials:

  • 5 ft. of cap
  • 5 ft. of base
  • 1x can of spray primer
  • 1x 3 in. drain
  • 1 can of mastic
  • 1x roll of 6 in. reinforcement mesh
New quotation based on assessment, June 22 2015:
  • Gum patches to three or more areas
  • Replace the drain with a new 3 in. unit
  • Roof replacement using an SBS 2 ply system
  • Estimated time: 20 hours

Saskatoon Commercial Flat Roof Quotation, November 2014

This commercial client in Saskatoon required an inspection and comprehensive quotation because of water damage in the building. As the roof would have to be re-sloped, repairs are not a viable option. Inspection Notes: A site inspection was done on November 26th, 2014 by a GRS representative in Saskatoon and the following was observed: 1. The roof access from the interior is through a closet sided door opening to a wall mounted ladder up to the roof hatch which is approximately 2 square ft. 2. The roof drain directly next to the hatch is dry while the perimeter of the center enclosure is retaining water which is now frozen, indicating a reverse inclination. 3. The suite or suites experiencing the water damage leaking were not inspected as prior arrangements had not been made at the time of this visit. Further, the management on site believed the windows to the suite were leaking and that the maintenance man would be doing further inspection of such. Should a closer inspection be required to obtain greater clarity of the damage and possible solutions an additional site visit would have to be arranged to gain access. 20141126_145833 20141126_145842 20141126_150000 20141126_150012 20141126_150036 20141126_150058 20141126_150106 20141126_150119 20141126_150134 20141126_150140 20141126_150153 20141126_150212 20141126_150226 20141126_150234 20141126_150258 20141126_150308 20141126_150320 20141126_150331 20141126_150344 20141126_150351 20141126_150405 20141126_150414 20141126_150423 20141126_150432 20141126_150436 20141126_150440 20141126_150459 20141126_150522 20141126_150550 20141126_150557 20141126_150601 20141126_150610 20141126_150620 20141126_150633 20141126_150643 20141126_150655 20141126_150703 20141126_150715 20141126_150742 20141126_150805 20141126_150820 20141126_150833 20141126_150849 The client was presented with a comprehensive quotation involving various replacement or recovery options.

Engineered Liquid Rubber Roof Recovery in Edmonton AB, October 2014

Below you will find a quotation, project manager notes, and a field report for an engineered liquid rubber roof recovery for an industrial metal roofing client in Edmonton, Alberta. Quotation, October 15 2014:
  • Engineered liquid rubber recovery to complete metal roof.
  • Pressure washing to clean, water test, and assess.
  • Fasteners will be tested and replaced as required to complete the roof deck, penetrations, and gutters.
  • Sheet metal repair and penetration saddle fabrication as required.
  • Remove old caulking as required.
  • Hand trowel all penetrations, roof to wall connections, fasteners, ridge, horizontal sheet seams, hidden gutters, and roof edge at external gutters with mesh and high grade rubber as required.
  • Apply liquid rubber coating, allow cure time, repeat hand trowel process above, and apply second coat of liquid rubber.
  • Liquid rubber to full inside face of parapet and top of parapet cap.
  • Ten year manufacturer warranty is extendable to twenty year maintenance agreement.
Project Manager Notes This roof structure may be a candidate for either a repair-maintenance program or an engineered liquid rubber coating - you may not have to replace it. I would not recommend a standard reflective elastomeric coating, or the SPF spray foam (with standard reflective coating), as this standard does not last well in a Western Canadian climate. Liquid rubber performs well in our climate as it has up to a 1200% expansion/contraction rate. If considering SPF for R-value, we strongly suggest covering the spray foam with liquid rubber or EPDM. Our crews do this work everyday with success. Generally speaking, metal roof systems are constant aggravating roof structures. Industrial systems have a deficient design - they are water-shedding, and not waterproofing, coverings. Metal expands and contracts more than any other roofing material and tend to leak from ice/snow loads. Leaks are also intermittent at seams (vertically where sheets are seamed together and horizontally where seams meet between sheets), penetrations, fasteners, around the perimeters at gutters, under the eaves, and at joints between roof and wall connections. Rust and corrosion may also develop. Traditional caulking or coating lasts a few seasons at best. Remedies are either spot repairs - maintenance with caulking or engineered coatings. Our recommendation in this instance is a high and engineered 2-ply liquid rubber polymer coating with a 10 year warranty, with the option of a 20 year maintenance contract for extended leak protection. Our client approved the quotation the same day for a roof recovery. Field Report, October 22 2014: After picking up the liquid rubber, we went to the work site and prepared the roof with seam tape around all seam tapes and penetrations. We then began coating the roof with liquid rubber and completed this site by the evening.

Leduc Industrial Metal Roof Maintenance, June 2014

This industrial client in Leduc, Alberta was provided with a quotation for various roofing options. Included were options for full metal roof replacement, roof recovery, and liquid rubber maintenance. This report follows the liquid rubber maintenance that was carried out to prevent further leaking. Inspection, June 10, 2014: There is leaking where the old building meets the new building on this site. There is a gutter which separates the 2 roofs and the leak is in the gutter. Ply’s in the gutter have deteriorated and the screws have popped through the ply’s. The original building has a sloped cladding roof which had the gutter originally, then they built the new building which is higher than the old building. The gutter between joins the two buildings.
Materials Required:
  • 2 pails of liquid rubber.

By the end of the day we had most of the units done and the ridge cap complete. I would say the job is about 60% finished. Tomorrow we will finish the gutters and fasteners. 20140618_084552_resized 20140618_090443_resized 20140618_101039_resized 20140618_101051_resized 20140618_101233_resized 20140618_120719_resized 20140618_120726_resized 20140618_140909_resized 20140618_142519_resized 20140618_142529_resized20140618_152045_resized20140618_152106_resized20140618_152120_resized20140618_152138_resized20140618_170236_resized20140618_170244_resized20140618_170250_resized20140618_170304_resized20140618_170327_resized20140618_170327_resized_120140618_170346_resized20140618_170357_resized Roof Report, June 20, 2014: Today we finished all of the units and the detailing. After that I had a new hire start the fasteners while the rest of us worked on the gutters. This was a big job as we had to coat and line the whole thing with LR and cloth, then apply a second coat of LR afterwards.
We helped finish the fasteners and the roof was complete. I had the customer come up to the roof and do a walk through and he was happy with the work. This site is 100% done.

  • 5 pails of LR brush grade.
  • 1 pail of trowel grade.
  • 2 rolls of 6 inch x 100 ft. mesh.

Edmonton Flat Roof Quotation and Recovery, August 2013

This report follows an initial quotation and subsequent roof recovery for a client with a flat roof system in Edmonton. The client was presented with various options ranging from temporary maintenance and repairs to full roof replacement. Due to the poor condition of the roof our project manager recommended a sustainable roof recovery using either an SBS modified or EPDM system. These options were selected as they are most suitable for the harsh and varying Edmonton weather. The client decided to go with the roof recovery option and an estimated completion time of 5 days (pending weather) was given. The crew then began work to re-condition the roof. The scope of work includes:
  • Sweeping gravel off of the roof and dispose into yard bin
  • Remove all metal and dispose into bin
  • Screw down fridge board with screws and plates (2-3 inch)
  • Torch down sopra lap tape to head seams
  • Prime perimeter with sopa flash
  • Apply peel n stick to perimeter (sopra base stick 95 gram)
  • Install new drain and retro fit with u-flow
  • Strip in boxes that the plumbing stacks are on with flam 180 base sheet and try to save the hardware on top of boxes (plumbing and roof vents)
  • Torch down 180 or 250 cap sheet (depends on what convoy can bring)
  • Strip perimeter and boxes with cap sheet stripping
  • Apply mastic to protrusions

St. Albert Liquid Rubber Roof Coating, July 2014

After GRS had attended to this site several times the year prior [links below], they returned to this residential client's building to inspect the liquid rubber resurfacing and see what steps need to be done to cease future hassles on this roof.

St. Albert Liquid Rubber Roof Coating, July 2013

This report is the first in a series of repairs and services that GRS has carried out for this particular client and their residential roofing system. The first covers a liquid rubber application to seal up some leaks in the existing roof. The article will be updated with links [at the bottom of this page] once the other reports have been posted. Quotation Delivered: June 13, 2013 GRS delivered a quotation to the client, detailing both the replacement and roof recovery options available to their existing roofing system. The client elected to move forward with an engineered liquid rubber roof recovery, so we booked them in for service to commence shortly.   Roof Report: July 16, 2013 The crew arrived on site for 4:30pm, setting up the area for the work to be carried out. Come 8:00pm, the site was fully prepared and the crew departed for the evening.   Roof Report: August 2, 2013 The GRS team went back to the client's site to get back to working on the recovery. The bulk of the day consisted of removing as much of the Portland cement as possible, and identifying all the possible areas of water ingress. Once the cement had been cleared out, they applied Barr squeegee-grade over the affected areas to smooth out the surface. The final task for the day was spraying on a flood coat of the liquid rubber, using up around one-third of the barrel of solution. With the leaks dealt with, the team departed the job site, considering it complete. Regrettably, there are no photos for this project that remain accessible - please accept our apologies! The featured image above is from a later project at the same location, giving an indication of the roof's status.   Follow-up Visits to the Site: http://edmontonroofrepair.ca/st-albert-liquid-rubber-roof-repair-december-2013/ http://edmontonroofrepair.ca/st-albert-temporary-tarp-roof-repair-december-2013/ http://edmontonroofrepair.ca/st-albert-liquid-rubber-roof-recovery-july-2013-2/   CODE: 60 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.
