Frisco Commerical Roofing – Advantages
There are many different roof systems available in today’s market, each with various strengths and weaknesses. Below I will describe each system briefly, and then list the pros and cons.
Thermoplastic and PVC- Single ply, can be mechanically attached, fully adhered or ballasted. Pros- Superior performance in ponding water situations. Very lightweight roofs, in the neighborhood of 30lbs. per 100 sq. ft. Comes in white if a cool roof is desired, or in several different colors for aesthetic concerns. Another plus with these roofs is that large custom made field sheets can be ordered from the factory, minimizing seams sealed by the crew on the jobsite. Resistant to ozone, algae and field seams are 3-4 times stronger than EPDM filed seams. There is also a tremendous amount of flexibility in the material. And since seams can be welded with hot air, there are no noxious fumes to deal with. Both 15 and 20 year warranties available.
Bottom line- Great roofs, especially on roofs that pond water heavily, as long as the roof is generally accessible only to authorized personnel. Check out here Frisco Commerical Roofing
Asphalt Modified Bitumen- This roof is what a lot of people call a rubber roof, when it is in fact composed mainly of asphalt. It comes in 3 ft. wide rolls and is usually torched down with an open flame, though they can be applied with hot air welders in certain conditions as well.
Pros- In my opinion, the biggest strength of these roofs is how well they stand up to outside stresses. They handle foot traffic better than any other membrane, and are difficult to puncture, especially if they have a granulated surface. These roofs are so tough in fact, that most insurance companies won’t even recognize hail damage as they do on other roofs (I have personally seen modified roofs absolutely pummeled with hail and come out completely undamaged)
Bottom line- With a good, experienced crew this can be a good roof on a building that does not pond water excessively. And if you have a building with a lot of rooftop foot traffic, this is probably the only way to go.
Foam roofs- This system is applied with a large spray unit, spraying two liquid components (isocyanate and resin) When the liquids are mixed together, they expand 20-30 times and will adhere to concrete, wood, steel and most existing roof systems, but according to the manufacturers, NOT to modified bitumen.
Pros- When complete, the roof is monolithic with no seams, fully adhered and has insulating properties.
Bottom line- Based on my admittedly limited experience with this system, I would not advise my clients to go this route when a new roof is needed.
EPDM Rubber- Rubber roofs can be fully adhered, mechanically fastened or weighed down with ballast (Riverbed gravel or pavers) They are versatile, appropriate for many installations and have a long track record.
Pros- Rubber roofs are relatively inexpensive, easy to install and repair. They are available in large sheets to minimize the number of field seams, and there is quite bit of flexibility in the membrane.
