Durable, dependable, and affordable protection that looks great
Composition shingles (typically known as asphalt shingles) are divided into two categories: organic and fiberglass. Organic composition shingles are manufactured with a cellulose fiber base made from recycled paper and wood fibers. This base is saturated with asphalt and given a mineral coating on one
side to resist weathering. Fiberglass shingles are made in a similar fashion, but the central core is fiberglass, which is more flexible and stronger than cellulose materials. All composition shingles come in a wide variety of colors and are rated by their projected life expectancy, typically 30-50 years. This is a great option if you’re looking for a standard, long-lasting roof at a great price.
TPO And PVC Composition
PVC and TPO are thermoplastics — they soften and become pliable when heated and harden when cooled. As a result, TPO and PVC membrane seams can be heat welded, forming a seamless watertight
top roof layer.
While TPO and PVC look alike, their material compositions are quite different. Polyvinyl chloride (PVC) is a synthetic thermoplastic polymer used in flexible form as a roofing material. PVC membranes also contain plasticizers to increase flexibility and other components such as U.V. inhibitors, color pigments, and biocides.
Thermoplastic olefin membrane (TPO) is a blend of polypropylene and ethylene-propylene polymers, color pigments, ultraviolet radiation absorbers, flame retardants, and other elements that may be added to achieve the desired physical properties. TPO doesn’t require plasticizers for flexibility and plasticity.
