Susceptibility Of Trailer Roof

Most trailer roofs are made up of aluminum or canvas that can withstand a lot of damaging factors. The effects of the environment on your trailer roof are what cause it to deteriorate over time.

Though the trailer roof seems tough, it is still susceptible to different damage. One common reason why trailer roofs deteriorate is because of rainwater, causing water damage or shingles on the roof surface.

The constant exposure to rain has a relative effect on the trailer, though none of these changes happen all of a sudden. As you know, acid rain increases the chance of roof stain because of the corrosive particles it contains.

When the trailer roof has already stained, acid rain gradually destroys the roof surface, and creates a tiny hole where a water leak takes place. Hence, most roof leaks may be avoided, and many can be quickly detected with a thorough inspection.

In addition, acid rain damage on the trailer roof may develop discoloration and streaking. For that matter, the lack of protective coating on the trailer roof is the reason why rain causes water damage.

  • EPDM coatings – It is an extremely durable synthetic rubber roofing membrane also known as an ethylene propylene diene monomer. Thus, property insulation will be improved with leaks repaired and an additional layer in place.
  • Eternabond – It is a sealant tape that seals any rip, tear, or open seam on any roof surface.
  • Rubberized leak stopper – It is usually formulated to penetrate deep into damaged areas and stop roof leaks.
  • Fiberglass repair tape – Reinforces repair areas and has high mechanical properties.
