Three most common problems with rubber roofs is improper installation shrinkage and the seams.
Rubber roofing problems drip rubber.
If the rubber is bonded prior to the adhesive drying then bubbles will appear under the membrane caused by the trapped vapour from the adhesive.
Shrinkage is a particularly serious problem on a larger size roof.
Epdm roofs are fully adhered or as many call it glued down.
Rubber will inevitably shrink leaks another inherent design problem is that after a few years this roof membrane simply begins to shrink slowly pulling away from parapet walls flashings corners drains and other areas.
Contact bonding adhesive is used for bonding the rubber membrane on upstands and around the perimeter of the roof deck.
Most people refer to a flat roof as a rubber roof.
The system is not attached mechanically.
While the rubber roofs are known to be durable they also need maintained.
Vapour from contact bonding adhesive.
However rubber roofs have many inherent.
The main reason for such popularity of rubber roofs is the lower initial price tag.
The adhesive is solvent based and must be allowed to gas off and become touch dry prior to bonding the membrane into position.
At that point leaks start penetrating these weak points.
Virtually the only negative for a rubber roof is appearance and even that drawback can be overcome with the use of rubber shingles or acrylic paint.
