Liquid Rubber Roof Repair, September 2015, Sherwood Park

This client's flat, metal roof required some patch work with liquid rubber. GRS sent out one of its technicians to carry out the quick repairs over the course of a few hours one day.   Roof Report: September 29, 2015 The three technicians began their day at 7:30, travelling to the garage to retrieve a trailer and some materials. Once loaded, they went out to the client's location and arrived around 10:15am. The technicians inspected the leak and subsequent water damage on the roof and loaded the work area with brushes and liquid rubber that would be suitable to this type of repair. They applied meshing to the expansion joint (approximately 25' long) and began applying liquid rubber to the new seam. Unfortunately, some rain rolling in hindered progress, but the crew took an early lunch and waited for the sun to break back out and help dry up the work area. All said and done, the crew was able to finish up the liquid rubber application by 2:00pm and depart the client's site without any problems arising to necessitate their return.

Engineered Liquid Rubber Metal Roof Recovery Ponoka Alberta, May 2014

Below you will find a series of reports from scope of work to completion for a large industrial metal roofing coating project. The Ponoka roofing repair crew provided the following assessment: Scope of Work, May 12 2014: The metal roof will be completed using two-ply engineered liquid rubber recovery. A pressure wash will be used to cleaning, water testing, and for site assessment. Test and replace fasteners as required to complete roof deck, penetrations, and gutters. We will provide sheet metal repair and penetration saddle fabrication as required, as well as remove old caulking. All:
  • Penetrations
  • Roof-to-wall connections
  • Fasteners
  • Ridge, horizontal sheet seams
  • Hidden gutters, and roof edging at external gutters
will be hand-troweled using mesh and high grade rubber as required. Liquid rubber coating will then be applied, allowing a cure time, followed by a repeated hand trowel process as above. This will be followed by a second coat of liquid rubber. The project manager provided a rationale for using engineered coating as well. Although the industrial standard would have been to recommend reflective elastomeric coating or SPF spray foam, they do not have longevity in a Western Canadian climate. Liquid rubber, on the other hand, has been shown to have a 1200% expansion and contraction rate. The idea was to get the "most mileage" out of the metal roofing, which have a high maintenance turnover due to leaks caused by expansion and contraction of the metal. Expenses also increase with wear and tear caused by corrosion. Using high end engineered liquid rubber polymer in this climate and context would skirt many of these ongoing maintenance problems.

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.
