Some materials get used repeatedly by the building owners that are financing a roof’s installation. A commercial roof differs from a residential rooftop in the nature of its design. Most commercial roofs are flat, or only slightly sloped.In that respect, each material for commercial roofing needs to offer some measure of protection from pooled water. On the other hand, each such material gets exposed to a different assortment of chemicals.

Liquid applied roofing

This seamless and monolithic structure gets custom-fitted to the roofing’s structure. Because it fills the cracks and gaps, it increases the observable level of the roof’s water-resistant protection. Still, the liquid must be applied to an existing structure.

Acrylic coating

Roofers In San Mateo know that acrylic coating gets applied to a rooftop with brushes, rollers or sprayers. It works best on roofs with a slight slope. Although this coating provides resistance to foot traffic, impacts, dust and erosion, it costs a good deal to install. For that reason, a building owner might feel inclined to think twice about using it.

Silicone coatings

These share some of the features associated with the acrylic coating. Each of the coatings adds to those features a marked water resistance. On the other hand, each of them displays a decreased level of durability. Moreover, a silicone-coated roof costs as much to install as one that gets covered with an acrylic material.

Single ply membranes

This rubber-like material gets rolled onto a low-sloping roof. It stays fastened to the roof’s structure through the utilization of fasteners, a chemical adhesive or ballasts. There are 3 types of single ply membranes: thermoplastic polyolefin (TPO), polyvinyl chloride (PVC) and ethylene propylene diene monomer (EPDM).

Building owners should not struggle to learn those long names. Yet it helps for a building owner to learn about the features associated with each group of letters. For instance, a rooftop that contains TPL demonstrates resistance to erosion. One that contains PVC displays resistance to the chemicals to which it might be exposed.

Asphalt shingles

The shingles create a flexible roofing system. Due to its flexibility, that particular system can be customized, so that it fits the rooftop’s structure. That feature becomes important, if a rooftop contains a number of large or small structures.


There are 3 different metals that get used to make roofs. A steel rooftop might get coated in aluminum or zinc. An aluminum rooftop costs more, but it should prove more durable. A zinc roof works best in an area where the air contains a great deal of chemicals or saline.All metal roofs share one important trait. If well-maintained, each of them has the ability to last up to 100 years.
