Tpo Roof Bubbles Rv

This is especially true for a tpo rv roof which is that thin skin of rubber material that lines the roof of your rig.

Tpo roof bubbles rv.

The rv manufacturer simply didn t apply the adhesive evenly or left some dirt on the roof that the adhesive couldn t stick to. Roof bubbling is just what it sounds like spots where the rubber has lifted off the surface of the roof and formed a bubble or blister. Tpo stands for thermoplastic polyolefin which just a short way of stating the primary chemical composition of the roof membrane. This type of roofing material comes in the form of a rubber membrane.

Anyone know if this means the roof will need to replaced or we should say no to this rv. The most common cause of roof bubbling is poor installation of the roof. In some instances the glue continues to cure after the roof material is in place and the gas causes an air pocket. This may be caused by high moisture inside the rv as well.

A tpo roof on an rv consists of a single ply roofing membrane. Tpo is the most popular rv roofing material today because of two reasons it is cheap and it is already colored white. Lots of cooking boiling water long hot showers with out running a fan or a c could cause moisture build up inside the rv that could collect on the sealing surface between the roof coating and sub roof as jim has mentioned above. During the manufacturing process the glue used to secure the roofing material to the plywood underlayment goes through a curing process.

I noticed some air bubbles in my rubber or tpo roof will they cause any problem. We are considering purchasing a used rv that has about 10 12 bubbles in the rubber roof. There are no inside water stains or signs of leaks. That vary in size from golf ball to dime size they appear to have air underneath.
