GRS Disciplines are diverse, single-source solutions, they include the following

Roof Repair

The Roof Repair, Drainage, and Waterproofing division of GRS is a significant part of our everyday business. We handle Repairs on Residential, Commercial, Industrial, and Institutional for Pitched, Metal, and Flat Roof Systems.

GRS has significant remediation operations in Roof Repair, Drainage, and Waterproofing - more specifically to Waterproofing large-expansive Metal and Flat Roofs on Commercial and Industrial facilities. 

In colder climates (such as Western Canada), extreme weather and freeze-thaw causes massive expansion and contraction in Roof Systems. This expansion and contraction exposes flaws in typical Low-Slope Metal or Flat Roofs. It is common for Commercial and Industrial Roof Membranes, Expansion Joints, Metal Roofs, Drainage Systems, Skylights, and Gutters to experience Roof Leaks, Ice Damming, and Gutter back-ups near impossible to resolve with conventional Roofing methods. 

Low-Slope Roofs (especially Low-Slope Metal Roofs) tend to be the most trouble-some of the aggravating Leaky Roofs. And often, our clients require long-term - timely solutions now. Satisfying day-to-day operational and safety requirements your business or industrial facility demands can be critical. 

GRS is an innovator, has significant experience, and is a proven leader in Roof Drainage and Waterproofing segments. Our web site, blog, and further consultation with GRS staff should direct you to permanent resolution of your Flat or Metal Roof Waterproofing challenges. 

Replacement Systems 

Our Roof Replacement crews are equipped for comprehensive work of any size and scope. We replace Roofing on Pitched, Metal & Flat Roofs for Residential, Commercial, and Industrial markets.

Sustainable Mandates

Few Roofing Contractors have a Sustainable Roofing mandate front and center. The sad truth is a significant percentage of landfill waste is a result of poor replacement practice.

Additionally, many buildings are not operating efficiently due to poor choice of Roof System and various other Building Envelope issues.  

GRS has a wide array of Sustainable initiatives, some of which include; Metal & Flat Roof Recovery / Retro-Fits, Overlays, VOC Free Engineered Liquid Rubber - Coatings, Cool, Green, Solar, Energy Efficient Roofs, Skylights, and Recycling. 

Cool (Energy Efficient Roofing) and Sustainable Systems for Sloped, Flat, and Metal systems is not the same in Vancouver or Southern BC as it is in the Northern Alberta oil sands around Fort McMurray. Fort McMurray, Calgary, Edmonton, Regina, and Vancouver all have different climates and subsequent requirements. GRS is equipped to assess and recommend systems that make sense for your building and geographical location. 

Inspection, Assessment, Infrared Surveys, and Reserve Fund Planning 

Roof analysis requires expert knowledge and experience. Our Senior Installation Management assist with Roof Inspections and Life Cycle Planning. GRS Services also include planning for extending the life of Flat and Metal Roofing, Infrared Inspections, Reserve Fund Planning, etc.

Maintenance Programs

Along with our Repair division, our Roof Maintenance division is a core component of the GRS Services.

Roof Vents, Attic Ventilation, Attic Moisture, and Ice Damming

One of the most common inquiries we receive on our toll free service line relates to home owners and business owners that have problems with proper Roof Ventilation, Attic Moisture (condensation), annoying and intermittent Roof Leaks, and Ice and Snow build up on the Roof.

GRS can assist in assessing and bringing forward solutions for Leaks, Attic Moisture, Ice Damming issues, and Ventilation problems.

Rooftop Snow and Ice Management

In Western Canada winter has our installers busy with Commercial & Industrial Roof Maintenance. In Vancouver our Roofing Service Techs are busy with the rain and roof leaks on buildings, and in areas like Fort McMurray, Edmonton, Red Deer, Canmore, Jasper, and Saskatoon the snow removal and ice damming on Roofs is a problem, and in areas like Calgary, Lethbridge, and Medicine Hat the freeze thaw aggravates roof systems all winter. 

A component of Maintenance is removing the snow and ice dams from Commercial and Industrial Systems. The execution of snow load removal and the engineering involved is more than simply shoveling the snow off large facilities. 

Our installers regularly travel the country and consult abroad for Roof Snow Management Services. We offer Commercial & Industrial Metal & Flat Roof Snow Removal (see Roof Snow Removal), Roof & Gutter De-icing, Ice Dam Removal, Snow Guards, Heat Trace/ Cables, Attic Ventilation & Condensation services, and Commercial & Industrial Roof / Gutter Snow and Ice Management Programs.
