Wal-Mart is one of the leading retail stores in the United States with roughly 9,000 stores around the world. 100 Wal-Mart stores are already making use of solar power, and the corporation has recently shared tothe public that it will be installing solar roofs on the US outlets. Before solar energy, then again, putting a roof on one Wal-Mart branch the size of four football fields (their biggest) was such a formidable process.

For large supermarket chains such as Wal-Mart, they won’t merely need to have a basic roof to cover every inch of their shops. While numerous small to medium-sized shops use residential roof options such as shingles and metal roofing, the bigger ones have particular specifications. In what way will a leading supermarket chain cover a tremendous roofing area while cutting back on maintenance and installation? Here are a few roofing options manufactured for commercial establishments.

Thermoplastics: A thermoplastic product is slightly similar to butter: it softens when subjected to heat and solidifies when it’s exposed to cold. The most largely-used materials of their kind are polyvinyl chloride (PVC) and thermoplastic olefin (TPO). Light in weight yet resilient, thermoplastics are one of the roof materials available in the market that are becoming increasingly sought-after.

As an alternative to boards and shingles, nevertheless, roofing contractors put rolls of thermoplastic material on an existing flat roof. The sheets will stick to the roof either from the welding completed by the roofing contractor or the heat on a hot weather. In addition, the fact that the product is ordinarily colored white increases its solar reflectivity, keeping the store cool and the produce cooler.

Thermosets: As opposed to thermoplastics, thermoset products such as ethylene propylene diene terpolymer (EPDM) can't be remolded following the first process. This is for the reason that the thermoset already has strength throughout the preliminary heating and molding process, where it is ordinarily in powder or liquid form. Roofers in NJ, nonetheless, state that thermoset roofing has its own advantages over both TPO and PVC. EPDM holds its form for a more prolonged period, ideal for creating permanent components.

Polyglass: This option of commercial roofing NJ roofing contractors offer is an altered bitumen roof that works most proficiently in places that usually get precipitation. It includes its own adhesive so that putting in a polyglass membrane on the roof is as simple as laying down the red carpet. A rooftop with more than one ply of roofing membrane and a modified bitumen cap sheet is called a hybrid system.
