EPDM roofing stands for Ethylene Propylene Diene Terpolymer. Although EPDM Roofing Contractors claim rubber roofing membrane as a robust, resilient, and long-lasting material, it does have certain disadvantages. EPDM is widely used as a commercial roofing option since it is one of the most prevalent and least expensive roofing materials. However, while it may save money in the short term, the expense of repairs and replacement may outweigh the initial savings. Continue reading to learn how to repair or upgrade your EPDM roof.
What is EPDM Roofing?
EPDM is created from recycled rubber goods with other components added throughout the production process to increase durability and strength, similar to the inner tube used in bicycle tyres (i.e., sawdust, slate). While EPDM is typically black in colour, lighter colours are becoming more popular because of their ability to reflect sunlight, albeit this may reduce UV protection and roof longevity.
The most popular EPDM installation method is to thoroughly attach or glue the whole membrane to the roofing system, then use rubber tape to strengthen the seams and flashing. EPDM roof systems have a 20 to 35-year life expectancy, depending on external factors such as harsh weather. When expertly placed, EPDM is also watertight and almost fire-resistant.
Limitations Of EPDM Roofing
EPDM roofs have a few limitations that are worth mentioning, despite their low cost and ease of installation:
Roof Seam Failure: If the adhesives wear out due to time and exposure, the roof seams may fail.
Flashing Failure: Water can infiltrate the roof if the flashing reinforcement fails.
Protrusions: Protrusions through the roof, such as HVAC systems, vents, or pipes, can provide natural failure spots when the roofing pushes away, exposing the exposed area to moisture, infestation, and harsh weather.
Shrinkage: EPDM rubber shrinks with time, causing the membrane to peel away from the walls and flashing, as well as open seams.
Punctures Can Be Difficult to Find: EPDM roofing is susceptible to punctures and tears in the membrane, which can be difficult to spot owing to the colour of the material or the presence of river rock ballast. When repair personnel walk on the roof, further punctures might occur, causing even more issues.
Water Damage: Once a seam has opened, water may readily reach the insulation and decking, causing even more damage and compromising the roof’s stability.
Is It Possible To Repair Or Replace An EPDM Roof?
Yes, repairing or upgrading an EPDM roof is a viable option. The technique entails taking identical and suitable materials and reconstructing the roof in a precise spot using those same supplies, much as it does with many other sorts of construction repairs. An EPDM roof should always be repaired with the materials suggested by the original manufacturer by a qualified EPDM Roofing Contractor.
Advantages Of Repairing An EPDM Roof
Cost-Effectiveness: Repairing damage or issues to an existing roof definitely extends its life. This can be a matter of years or even decades in many circumstances.
Low Invasiveness: Repairing an EPDM roof is comparatively non-invasive, as opposed to certain other forms of roofing repairs. All except the most extreme instances, businesses may continue as usual.
Simple Turn Around: EPDM roof repairs are often performed swiftly and with minimal disturbance.
Disadvantages Of Repairing An EPDM Roof
Failure Rate: Repairs on an EPDM roof generally don’t last long, resulting in further issues.
Finding Exact Spot Can Be Challenging: Finding the exact spot that has to be fixed can be challenging, especially if there is already a rock ballast in place. A skilled roofing contractor with sophisticated infrared thermography capable of detecting moisture and potential leaks is one viable answer.
Ineffective Against Severe Damage or Deterioration: The more damage that is repaired, the higher the risk of further integrity failures.
What Qualifies A Candidate As Good Or Bad For Repair?
In general, if the leaks are contained within a small section of the roof and can be fixed with similar material, the roof is not too old or exhibiting indications of wear, and the majority of the seams are holding well, the roof is a solid candidate for a successful repair. Also, if no significant levels of saturation have been detected beneath the roof, which is common when a repair is postponed or delayed, enabling further damage to occur.
The roof, on the other hand, may not be a viable candidate if there are several leaks on the roof in various spots or if the seams are no longer holding owing to failed adhesives. It may also be time to consider a replacement if the membrane is old and fragile, the material is dropping between the scrim, or the roof is soaked under the surface.
In general, if the EPDM roof is still useable and just has a few leaky patches, it’s a good candidate for repairs.
