Modified Bitumen Flat Roof Repair

Repairing a Modified Bitumen roof used to be offered only as a complete replacement system. Now, roof coatings are what are used in performing successful spot repairs. This stops the leak, saves finances when compared to the cost of a new system and leads to a longer roof life. When a roof coating repair is done properly the repair will not need to be removed or touched until a full restoration is required.

Before having any work done on your roof, the most important step is to have a professional inspection completed. When an infrared scan is used in a roof inspection it ensures that the right area will be repaired properly the first time.

A special detail in modified bitumen roofing is that it permits the re-use of the insulation and other components including the waterproofing membrane themselves. The materials beneath the roofing membrane including the insulation and cover board as well as the quality of the methods employed in installing them are determining factors on how long the roof can last and how much of the material can be reused for repair.

Making spot repairs on a modified bitumen roof is not a scary task because with experience it is a simple process. The material even comes in rolls for ease of application and of course this means they are factory manufactured and must meet certain standards due to quality control.

If your modified bitumen roof has been in need of ongoing repairs, please do not hesitate to give us a call. There is a chance that if repeated repairs are being required that the incorrect location is being worked on resulting in further damage.

Keep in mind that our repair services come with a full warranty and we can easily put together a comprehensive roof maintenance plan for your roof.

What is Modified Bitumen?

Modified Bitumen (MB) is asphalt that has had modifiers added to it to give it plastic or rubber-like properties. Installed in layers which are either torch welded or adhered using factory applied adhesive Modified Bitumen can be a cost-effective alternative. The longevity and warranty received on the product is dependent on the maintenance, quality of and number of layers installed.

Engineered modified bitumen originated in Europe in the mid 1960's and has become a standard commercial roof application and has been being successfully used in Canada since approximately 1975.

There are numerous surfacing options for this system which include a factory applied mineral surface, gravel surface, including “cool roof” coatings which are highly-reflective to save on building cooling costs. Mineral-surfaced roofing products are typically furnished with white granules, but are also available in designer colors to match asphalt shingles or to otherwise compliment the overall building design.

The latest innovation to modified bitumen is the self-adhering sheet. Using special combinations of polymers to modify the underside of the sheet, the rolls are manufactured with a release paper. When we remove the release paper and the sheet is rolled out, the sheet adheres itself to the substrate. This method eliminates the risks associated with the use of torches, hot asphalt, and is completely free of VOC (volatile organic chemicals) fumes during and after roof application.
