Article: Liquid Rubber Roof Coating. Industrial Waterproofing. Whitecourt, Alberta.
This is a site report for a liquid rubber roof coating to waterproof an industrial standing seam metal roof in Whitecourt, Alberta. Roof maintenance coatings will extend the life of a metal roof for many years avoiding costly roof replacement.
We started applying liquid rubber to metal roof systems in Canada about six years ago.
At first we were concerned because many of the elastomeric roof coatings are manufactured for the wider market - which is the USA. Of course this causes a challenge because most of the USA needs reflect or white roof coatings due to the temperature. If you have more warm days than cold days it is best to use a white or cool roof coating in most instances. If you have more cold days than warm days then a dark coating is typically the best choice.
We used various elastomeric coatings in various areas of Canada and over time came to be most confident in applying liquid rubber.
Engineered coatings with advanced polymer technology has changed the game for coating roofs in Canada.
Now that we have millions of square feet of coatings on roofs in Canada we can confidently say that liquid rubber is the best coating you can get for cold climates.
Some Liquid Rubber Facts and Ten Benefits of Using Liquid Rubber on Metal Roofs:
- Liquid rubber will waterproof your metal roof. It is monolithic. In other words, when we coat a roof everything is tied in to the main coating. The penetration holes, the parapet walls, the flashing, curbs, crickets and more. There is nowhere for the water to back up or penetrate openings. This is the primary advantage of a coating vs. a membrane system or a metal panel system.
- It is a rust inhibitor. If you have a metal roof that is either rusting or will rust due to the materials stored inside, liquid rubber is the best choice.
- It is a net benefit for building efficiency in cold climates. Recent studies have confirmed what we knew all along. Simply google key word phrases such as "cool roofing studies for cold climates" and you will find that coating a roof with a cool or white coating in a cold climate is not a wise decision.
- It will melt ice dams quicker and it will melt ice in the gutter quicker. A common problem with metal roof systems in cold climates is ice. When ice dams form they cause havoc with metal roof seams between panels, roof vents and curbs and ice in the gutter can "wick" up and under the eave area and melt and cause leaks at the inner wall. We can tie in the gutter system, the wall area and the roof with liquid rubber so no ice can "wick" in to your roof system.
- Coating industrial, commercial and any sort of internal gutter system with liquid rubber will solve a lot of problems you may be experiencing with your gutter systems. Especially troublesome are steel erected buildings with parapet walls that have low slope metal roofs and internal gutter systems along the inside of the parapet walls. Liquid rubber can solve that by tying the roof, the gutter and the parapet wall all together as one monolithic membrane system.
- It is UV stable. It does not need a reflective coating. It does not need pea gravel. It doesn't peel and crack in the sun.
- Liquid Rubber is non toxic, VOC free and solvent free. It cures to provide a seamless, fully adhered flexible membrane. It protects from UV, salt, thermal cycling and harmful chemicals. It is both worker and environmentally safe and is available for commercial, industrial and residential markets.
- When we coat your roof it is considered a maintenance invoiced service. Many customers tell us there are tax benefits to maintenance vs. replacement. Check with your accountant.
- Liquid Rubber works well in cold climates. It has an expansion rate of up to 1000%. Unlike other products, buildings that have liquid rubber installed by us in cold climates with heavy snow loads are doing well. We have liquid rubber installations in the coldest areas of Canada with snow loads over ten feet and liquid rubber has performed like no other product we can find (specifically for cold climates).
- It has an excellent cost value. In other words, to replace a standing seam industrial roof it can cost between 9.00 - 30.00 per square foot. Liquid rubber is a fraction of the cost. It has a ten year warranty with an optional twenty year service agreement available from us. If you need R value, we can spray your roof with foam and cover it in liquid rubber. But if you just need waterproofing, liquid rubber is all you need.

Here's a video showing our crews at work and the scope of work typically followed when coating metal roof systems:
Below is the roof coating crew's account of this liquid rubber installation.
November 7, 2014: Crew attends to site location near Whitecourt, Alberta.
This is a electrical sub station that added an addition on to their building. The first deficiency was where they joined the building together there was an open split on both sides. Water was running down and leaking in to the building. I sealed it in with seam tape and Liquid Rubber. After that we prepared the roof fasteners, seams, etc and then we started to roll in the roof. We didn't spray this roof because it was smaller in size. Unfortunately it started to rain when we got to the 70% mark and there is rain in the forecast for many days. We will have to return at a later date to finish the coating.
April 14, 2015: Roof Coating Crew Re-Attends to Site.
When we finished 70% of the roof last season the rain came in and lasted for days and then turned in to a snow storm so this roof had to be completed spring of 2015 when weather was suitable enough to apply liquid rubber.
9:50 am arrived on site.
We arrived on site and we did our daily tool box meetings. We then did a site orientation with the engineering company who hired us. 11:00 am we got on the roof. One of us started painting the ribs with Liquid Rubber while I started coating panels with Liquid Rubber. We coated about 1100 sq. ft. It took awhile due to the slope of the roof. At the end of the job the customer looked over the work and was very happy.
