Want to Make Sure Your Roof Is Completely Watertight This Year?

What Exactly Is Membrane Roofing?

Membrane

roofing

is a system which is designed to reduce leaks and pooling that often occurs with other materials. This system is slowly replacing the more traditional asphalt roof found in most buildings today. It is used on roofs which are flat or have a slight pitch. There are 3 kinds of membrane systems which are modified bitumen, thermoset membrane, and thermoplastic membrane.

hermoset

membrane is sheets of rubber which are laid across the roof’s surface with their seams overlapping. These seams will then be heated, which causes the rubber to melt together. Due to the numerous kinds of rubber used with this system, the heat causes a chemical bond, which makes them stronger. The rubber has varying thickness, which makes it almost impenetrable when it comes to leaks.

Thermoplastic membrane systems are very similar to the above, however, use PVC or other similar materials and not rubber. The PVC sheets will not bond chemically when heated, however, will form a tight seal which will stop water from getting through the seams. These systems are not as expensive as their counterpart thermoset membranes, but, does require regular maintenance and repairs.

Modified bitumen systems are probably the most affordable kind of membrane

roofing

and the most commonly used for residential roofs. Rubber compounds and other such modifiers will be added to the asphalt compounds, which are then heated with a torch so it melts and forms a tight seal. New modified bitumen systems can now be used without any heat. The asphalt and rubber compounds will be applied to sheets while they are still in the factory, which will allow installers to lay the self-adhesive sheets directly onto the roof,

with the seams overlapping. If you are worried about your roof then you should contact Arcade Roofing & Home Improvement in Brooklyn, NY now at (718) 288-9881.
