PVC Roofing Install & Replacement Contractors, Birmingham, AL Licensed & Insured Roofers
PolyVinyl Chloride (PVC) is a variety of plastic built from the reaction of hydrochloric acid and ethylene with oxygen. It is usually used for plumbing pipelines, but nowadays it is being employed as a new type of roofing system, designed for flat roofs or conservatories. PVC roofing membrane is built from 2 plies of PVC product with polyester support in between them, and the seams hot-air welded making it more leak-proof and durable. PVC roofs are exceptionally resistant to fire, chemicals, UV radiation, moisture, and puddles.
Flat PVC roofs exist for visual appeals and comfort. When including in the house, it is simpler to install a flat PVC roof as compared to trying to find material that will complement with the older portion of the roof. In commercial buildings, such roofs use extra area for setting up outside HVAC systems.
PVC roofS are resilient and strong with a minimum of 300 pounds per inch (PPI) as compared to industry standards of 200 PPI. Given that these systems are hot welded into place, they are leak-proof, and the bonded portion is certainly stronger than the PVC itself. They are likewise energy efficient, specifically the white ones because they reflect instead of taking in the sun's rays. This roof is likewise easy to repair and keep.
Setup of PVC roofing
PVC roofing is among the very best, if not the best, single ply roofing system currently available in the market. PVC roofing can either be mechanically secured or fully fastened and is resistant to flame, chemicals, and grease. When mechanically attached, concealed metal plates are used to protect concealed sections of the membrane to the roof deck. However, when they fully attach, they are glued onto the roof deck. This is more costly than mechanical attachment. Both of these installation approaches feature lifetime warranties, but many residential and small commercial installations prefer mechanically fastening the PVC to the roof deck.
With PVC roofing, structural integrity is assured from the get-go since PVC roofing is enhanced right out of the box. This reinforcement is done utilizing polyester scrim, material mesh, or mat placed into the product.
In spite of being very durable, PVC roofing is costly to set up. Aside from the PVC membrane, one needs to factor in expense for insulation panels which assist with energy expenses. Many contractors prefer mechanically securing the membrane rather than hot welding it because this prevents uplift. All these add to final labor expenses. PVC can last for up to 30 years.
PVC roofing can be prefabricated and personalized for your roof. In this manner, your roof is measured to cover your walls, curbs, penetrations, to name a few such that the roof is custom made and developed to fit those dimensions. The advantage that comes with prefabrication is that it reduces up to 85% of all the field seams. Seams are the weakest section in any roof; for that reason, prefabrication substantially boosts the roof considering that the manufacturer makes them in a quality-controlled environment.
Furthermore, PVC roof can be ballasted such that the roof membrane is held together by aggregate. Ballasting the roof membrane is cheap, but it is a dying breed because it puts in unneeded weight to a property's structure. Furthermore, if a leak does occur, it can not be mended because moving around the heavy aggregate in order to get to the cause of the leakage is such a trouble. It is much better to avoid PVC ballasted roofs because they might be easy to install but there is very little one can possibly do with them in regards to upkeep as soon as setup is done.
