Spray Foam Roof Repair Request, September 2015, Esterhazy SK

This client in Esterhazy, SK had some problems in 2014 after a big storm. The third-floor rental units of this building had some water damage then, but none since. They reached out to GRS to find a local roofing company that specializes in flat roofs. Our project management worked with them to begin scheduling a team to come out from Regina or Saskatoon. Request For Service: September 24, 2015 The client called in to GRS to see if any roofers could make their way out to the small town of Esterhazy, SK and inspect their roof to see what might've caused water damage in the rental units below a year prior (July 2014). There have been no reports of further water ingress since, but their insurance company required that the roof be attended to before they can proceed with the claim. With Esterhazy, SK being so far away from major centres of operation for GRS, scheduling was a little bit difficult, so the project manager sought as much up-front information as possible about the site and the state of the roof before dispatching crew to go on-site. Submitted Photos: September 25, 2015 The client sent in photos that show the state of the roof and what kind of system the GRS crew would be dealing with upon their arrival. In doing so, it ensures that everybody handling this project with GRS understands what would need to be done in order to correctly patch the roof without any excess travel time such a distance from Regina, where the repair team would be departing from.

The client submitted photos of the initial state of their roof.

There were some tears running significant lengths of the roof which required patching.
Image 3
There had been a big storm in 2014, which contributed to water damage and ingress in some of the rental units underneath the roof.

A spray foam company had originally installed the roof. Heavy weather conditions resulting in damage are often covered under warranty.
Image 8
There had been some residual water standing that had culminated around blistering that had also formed in the assembly.

On top of the blistering, some air/gas bubbles had become trapped. If not addressed, these can eventually lead to tears and holes.

Tearing and blisters were also found along the perimeter of the roof.

The foam joining the roof and the edge flashing was exposed up to the downspout. Water had not been draining correctly, which also culminated into leaks.
  Correspondence: September 25, 2015 The project manager receiving these photos noted the poorly state of the roof system and asked how long ago it was installed. The client responded that it had been installed in 2008 by a Spray Foam company. In dealing with these types of failures, it's important to consider if the system is under warranty or not. Most of the systems and materials that GRS installs on flat roofs come with 20-40 years of expected lifetime and warranty coverage. The project manager relayed this information to the client, as the repairs could be covered by the company that performed the original installation, or the material manufacturer. The client then located the paperwork from the 2008 installation and found that their roof bears a 10-year warranty against leaks. It was at that point that the GRS  project manager advised returning to the original roofing company and advising them of the problems with the structure. The client heeded the advice, and the service request was then closed. < End Report > CODE: 1000 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Residential Roof Leak Repair in Edmonton AB, July 22 2015

Below you will find an initial assessment for an ongoing residential site by our Edmonton roofing repair crew. More reports will be posted as they become available. Initial Assessment, July 22 2015: We arrived on-site at 1:00 pm and were lead by the client to two leaks in the shop. One was coming from around the skylight, and another one around the chimney stack in the middle near the edge of the roof. Upon inspecting the roof top-side, we observed that the acrylic MASTIC around the chimney was cracking and lifting in areas. It should be removed and replaced with seam tape and liquid rubber. The penetrations require the same. It is only a matter of time until it begins to leak around the entire skylight. There are also cracks and splits in the skylight, which seems to have had been coated with spray foam. The metal gum box also needs to be topped off. There is a metal boot top-side as well that looks like it was only spray foamed. The roof measurements are 85 ft. long by 51 ft. wide, and the skylight was 4 ft. x 4 ft. It should take 25 man hours to clean and repair the penetrations, apply some gum patch into the metal boot, and cover the foam/top up the gum box with rubber MASTIC. < TO BE CONTINUED > Code: 154 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

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.
