Tpo Roof Bubbles Rv

We are considering purchasing a used rv that has about 10 12 bubbles in the rubber roof.

Tpo roof bubbles rv.

Tpo stands for thermoplastic polyolefin which just a short way of stating the primary chemical composition of the roof membrane. The most common cause of roof bubbling is poor installation of the roof. The rv manufacturer simply didn t apply the adhesive evenly or left some dirt on the roof that the adhesive couldn t stick to. Anyone know if this means the roof will need to replaced or we should say no to this rv.

In some instances the glue continues to cure after the roof material is in place and the gas causes an air pocket. To attach the tpo membrane on your rv you can either join it mechanically using heavy duty screws or staples or glue it on the surface using specialized adhesives. This type of roofing material comes in the form of a rubber membrane. This may be caused by high moisture inside the rv as well.

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. 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 is the most popular rv roofing material today because of two reasons it is cheap and it is already colored white.

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. That vary in size from golf ball to dime size they appear to have air underneath. 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. A tpo roof on an rv consists of a single ply roofing membrane.
