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.

Edmonton Commercial Roof Repair Quotation, September 2014

This client reached out to GRS to receive a quotation for repairs to their commercial residential building. They included a report (from which the subsequent photos and their captions are obtained), which allowed us to return a quotation for the repairs they sought. Client's Report Received: September 17, 2014 The client sent their report into the GRS office, detailing problems with the current roof and explaining what kind of services they would like performed in the various problem spots. This allowed our account representative to deliver and present an accurate quote for the repairs, in addition to positioning the possibility of a roof replacement as had been discussed with the client in prior communications. GRS Note: The photos and comments below were included in an Inspection Report carried out by a third-party and, while informative, may not fully represent the opinions of GRS. Sometimes clients will submit their own photos or reports that they've independently sourced; all of this information helps us build a proper quote without needing to physically arrive on site.

Sealant installed onto storm collar has deteriorated and is no longer functioning as intended. Existing sealant should be removed and new sealant applied.
Conclusion:
This report is based on visual observations of the roof system. No destructive testing was conducted to analyze the underlying components of the roof system. With proper maintenance the remaining service life of the roof system is approximately Three (3) to Six (6) years. Maintenance should include installing protective surfacing, repairing membrane deficiencies, repairing membrane blisters, securing metal flashings, installing drain screen, installing membrane protection, removing debris from the drain screen and applying sealant to the storm collar. < End of Third-Party Inspection Report >

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:

  1. Site Visit Done. Initial Assessment Completed. Photos on file (see Krain Consulting report).
  2. Options for roof replacement, roof overlay, repairs, and regular maintenance attached.
    1. Full roof replacement is not required except at garage portion where the installation crew will determine how much to take out when they open roofing system.
    2. An EPDM, TPO, or PVC roofing system overlay is a reasonable option for this roof.
    3. A roof overlay saves significant costs, provides environmental relief as old system does not end up in the waste, and all the roof overlay systems are very successful.
    4. The deciding factor when considering a roof overlay is whether the preference is a black roof (drawing the sun in) or a white roof (a cool roof for more efficient function).
    5. Repairs to existing roof is a consideration, but not recommended considering the number of failures.
  3. Roof Flashing.
    1. The existing roof flashing is in moderately good shape. It could be replaced but it is most definitely not required. We suggest keeping as much of the old flashing as possible.
    2. We suggest keeping as much of the old flashing in place as possible. When the new roofing system is retrofitted, the Senior Installation Manager would instruct the crew to save as much of the old flashing as possible (unless client decides to simply replace all flashings).
    3. The roof flashing invoicing (whether all new is ordered or the existing flashing is modified) would be a separate invoice. Our sheet metal / flashing crew is about two weeks behind our flat roof membrane applicators so we would bill the flashing separate of the roofing system.
  4. Eaves, Downs, and Scuppers.
    1. Crew to be instructed to slope roof in such a way that the flow of water moves toward the east and south.
    2. Custom fabricated architecturally designed eaves and gutters with external scuppers (drainage to gutter area) will be added to back of home and east side. Client and installation manager to determine where the downspouts will send water to on east side of property.
5. Perform regular maintenance once or twice per year thereafter.
