Leaking Metal Roof Systems

A metal roof on a residential project may or may not be installed on a high slope. If installed on a high slope, it is less likely to leak However, many industrial and commercial roof systems are low slope. If a metal roof is installed on a low slope, chances are leaks will occur.

Why does Metal Roofing Leak?

Metal roofing expands and contracts with changing weather conditions, which causes the roof fastener holes to get larger over time. This is especially true in our unpredictable Western Canadian climate. Expansion and contraction of the metal causes the seams to expand and contract which can cause leaking as the seams  become less crimped or locked over time. Ice damming and snow loads can also cause metal roofing to leak. Ice damming can even back up at the eave of a metal roof,  especially if there is a gutter system that is frozen solid. Ice damming can move roof vents or various roof openings enough to cause a leak. Snow loads can weigh down metal roofing so much that seams become more exposed. Caulking of roof vents and roof openings become brittle and crack over time which can also cause leaks.

Metal roofing will also trap moisture on the underside, causing condensation that will eventually result in a roof leak.

Metal roofing is a watershed product,  not to be mistaken as a waterproofing product. Waterproofing is a completely different discipline in roofing. Metal systems are inherently designed to be secure yet will eventually leak.

Metal Roofing – Roof Ice Damming Leaks

Metal roofing is one of the best roofing systems you can purchase in the world. It will outlast most other roofing surfaces. However, there are some exceptions that will last longer, such as: slate roofing, rubber roofing, concrete tiles, synthetic tiles. Nonetheless, a metal roof is undeniably one of the longest lasting roofing materials in the world.

What separates a roof that lasts fifty years and a roof that lasts twenty years is the quality of roofing material, the metal roofer’s installation specifications, and proper maintenance of the roof over the years.

Metal Roofing – Installation is Key

Quality metal roofing costs more than the less expensive versions.  A lower quality, less expensive metal roof may only last fifteen or twenty years. whereas a metal roof that is installed using a higher quality will last fifty years. In either instance, if the metal roof is installed poorly, a fifty year metal roof may only last a year.

A metal roof installation needs to be precise and needs to allow for the fact that it  is a watershed and not waterproofing material. By its nature, a metal roof  watersheds, therefore it is expected to eventually leak. Whether that leak will affect you is determined by a number of variables such as hidden fasteners that provide more protection than exposed fasteners, using locking panels, using a steep versus a low-slope system, and a premium roof underlay beneath the metal roofing material.

Replacement, Repair, or Restoration. What’s the Answer?

There are a number of ways to avoid the problem prior to needing to replace a metal roof. We won’t go in to those ways in this article, as this article is to assist those wanting to explore avenues of metal roof restoration, repair, or replacement.

General Roofing Systems will typically suggest a few answers to your metal roof leak problems:

Maintenance
Maintenance should be conducted on an annual basis. Caulking made for metal roofing is available and should be re-done every fall. Be sure gutters are kept clear during the winter. DO NOT let your gutters freeze up as this will cause problems with your metal roof. Also, snow loads are important; try your best to maintain a reasonable amount of snow on your roof. If possible, keep the snow off.

Repair
Repairs usually involve maintenance such as caulking, replacement of vents or some form of sheet metal fabrication for a detail on the metal roof. If the roof leak and subsequent repair isn’t focused to a specific issue, but is more of an intermittent leak issue, then you are likely best looking at a metal roof coating or a metal roof replacement.

Roof Coating – Liquid Rubber Technology

Coating
Coatings were once looked at as a short term solution.

New coating technology is extremely successful, long lasting, consistent, and has finally solved the roof expansion and contraction problem.

Liquid rubber polyether roof coating technologies are solvent free, maintain 900% elongation, UV resistant, bond to almost any construction or substrate, liquid cold applied, elastomeric, great for green roof applications, 100% solids and will not shrink, they are compliant with all known environmental requirements, resistant to thermal shock and slumping at high temperatures.

The first benefit of coating a metal roof vs. replacing your roof: Metal roof repair, or coatings, are considered maintenance and as a result are a tax deduction.

The second benefit of metal roof coating in today’s market is that the new liquid rubber coatings are highly effective, even more so than most new metal roof systems. The new liquid rubber coatings are highly advanced (developed as a result of nanotechnology) and the elongation values are in the order of 900% and are UV resistant. The roof coatings move with the expansion and contraction of the metal roof and keeping it waterproof.

The third benefit of the new metal roof coatings is that a roof coating will cost you about 1/3 to 1/2 the price that a new roof replacement would.

The final benefit to coof coatings worth mentioning is that the new liquid rubber polyether technology last several years.  We have a ten year warranty with an option to extend to twenty years in some instances (requiring a maintenance coat at 10 years typically).

Roofing, Roof Repair – Preventative Roof Maintenance Encouraged Before Winter Comes!

Fall has arrived and winter is just around the corner. This time of year is when people tend to be the most busy, with having just came back from vacation to children starting school and various other activities. With so much on the go for people, the last thing that you want to think about is the ROOF!

Yet the reality remains, this is also the busiest time for roofers, as facility managers and homeowners alike start to prepare the buildings for the harsh weather that winter brings. This is the best time to consider whether or not your roof has any current issues that need attending to.

The snow loads in Central Alberta and Northern Alberta were record setting. For many of the roof systems, if they did not fail or have issues last winter, it is almost certain they will have problems this winter.

We have  watched several commercial and industrial roofs completely fail in the Edmonton and Red Deer areas. The roofs literally buckled under the pressure from all the weight of the snow we received. Yet we believe this could have less severe had proper maintenance been taking place before the season hit.

This  winter has proven to be highly unusual. We experience such diversities in the climates all around western Canada. For example, in Vancouver our crews were busy with torrential rain, while in Saskatoon and Regina they were busy with snow falls, and in Calgary it was a constant cycle of  freeze and thaw. All this diverse weather  kept our roofing crews at complete capacity, often having to work many hours of overtime.

Some things to consider for your commercial, industrial, and residential roof maintenance prior to the next winter setting in;

Flat Roofing: Any flat roofing that took on heavy snow loads will most definitely require some attention. We highly recommend that owners heed the warnings from the previous season and at least asses the current quality of there roof, it would be best to have this assessment completed before the first snow fall. We have an annual roof repair and maintenance check list for flat roofing and the maintenance required to be completed listed on our website.


Metal Roofing: Metal roofing was hit the hardest last winter. The reason is that metal roof systems, especially commercial and industrial, had snow loads that compromised the metal roof panel seaming. In other words, the metal panels on the roof have been warped or pressed down so hard that the seams between the panels and the fasteners are compromised. The other issue we are seeing with industrial and commercial metal roofing this year is that many of the gutter systems are damaged.

The problem with metal roof systems on industrial buildings is that when the ice builds up in the gutter it will then back up and enter the building under the metal cladding. Fortunately, there are excellent solutions for metal roof issues yet most cases do require a full replacement.

Nowadays we can coat metal roofing with liquid rubbers. This is a elastomeric spray on roof coatings that will seal the metal roof seams, fasteners, and vents.

In addition to this, our main web site contains several pages on metal roofing, roof coatings, and roof repairs. You can find this information listed below with  the following links:

Residential Roofs: These systems did not have nearly as many structural  failures that occurred with Industrial and Commercial roofing last year. Although that is not saying that residential roofs, roof attic ventilation and condensation did not have their fair share of complications.  The reason being is that with the snow loads on roofs, the ice damming, condensation and ice backups in gutters, caused numerous problems.

As stated earlier, this winter season has been a treacherous one. Due to this fact, GRS would like to remind everyone to have an assessment completed on their roof for the next season BEFORE snow begins to fall.
