Blistering Modified Bitumen Roofing

They perform well in both extremely hot and bitterly cold conditions perfect for the weather extremes common across new jersey and nearby states.

Blistering modified bitumen roofing. Roofing membranes for low slope application are generally asphalt or polymer based 1 bitumen has been used as a roof water proofing agent for many years. Unfortunately some manufacturers do not use enough app to save money and this means the modified bitumen roofing. Blistering in sbs polymer modified bituminous roofing membrane systems 1. All conventional low slope roof systems experience blisters in some form.

Roof systems with membranes are more prone to blistering because blisters are formed by gaps between the membrane plies or between the underlying substrate and the membrane. Modified bitumen is a type of asphalt product that can be applied in a number of ways to the roof in both hot and cold temperatures. Fill the void underneath the membrane with bitumen and then press the membrane back into place. Blisters in a modified bitumen roof.

To make bitumen tougher and more elastic a synthetic polymer is usually added. Keep in mind that this particular repair method is only advisable if the membrane is otherwise undamaged. One of the longer lasting roofing options for flat roofs is bitumen roofing or a modified bitumen roof. The resulting mixture is called modified bitumen.

Modified bitumen roofing has been around since the 1970s when it was developed to address ongoing issues with traditional asphalt roofs. Membrane samples were removed from several existing modified bituminous roofs containing blisters. Membrane systems are most susceptible to blistering because blisters are formed by voids between the plies or at the point between the substrate and the membrane. Tpo roofs have been around since the 1990s.

Roof blisters are not limited to one type of roof system. Modified bitumen roofing was designed to improve the original version by adding substances like app atactic polypropylene. They appear in all types of roofing systems residential and commercial. The coating adds even more resistance to the elements and prevents debris from damaging the bitumen underneath.

A roof blister is a pocket of air trapped between the layers of a roof membrane between the components of a roof assembly or within a layered roofing product such as an asphalt shingle. Bitumen roof if the membrane. This made sure that the newer systems were resistant to uv light oxidation cracking and blistering. Summary the cause of blistering in modified bituminous roofing membrane systems was investigated.

Alternatively on a bitumen roof you may be able to cut an x into the blister and then peel back the loose membrane layers. As an alternative on asphalt bur membranes only two plies of smooth surfaced modified bitumen sheets. Their mechanical behaviour was characterized by tensile tests. Modified bitumen is an excellent material for covering a roof but it can be made even more durable through the addition of rubberized coatings.
