When people consider asphalt or asphalts, they usually think about the hot, gooey things used to pave roads and cover potholes. However, did you know that asphalt, when mixed with specific modifiers, can be made into a roofing called "modified asphalts?" Modified asphalt roofing in Chicago is a prominent and long lasting covering used for commercial buildings with flat roofing systems.

What is modified asphalts roof covering?

Although modified bitumen is considered a type of roof asphalt, it's extremely different from asphalt shingles, which are generally used for domestic properties. Manufacturers of modified asphalts roofing materials have the ability to improve the performance and strength of regular asphalt by mixing it with artificial rubbers then bonding it with sheets of polyester or fiberglass. They are typically sold in rolls about one meter large and offered in one, two, or three ply systems.

When was it first used?

It was in the mid-1960s when modified asphalts was established in Europe, but it was only in 1975 that it was used as a roofing material in the United States and Canada. Since then, its manufacturing and installment process have been improved to ensure resilience and security. For example, the right amounts and ratio of modifiers have been determined to boost versatility and avoid early degeneration.

What are its advantages?

Its waterproofing capacities are among the main benefits of selecting modified asphalts roof. And in relation to product cost and installment, customized bitumen is very competitive with other preferred roof covering materials in the market. Their rubber-like consistency and features provide exceptional weather condition resistance and durability.

What are its typical kinds?

Common sorts of modified asphalt roofing in Hammond and Chicago, Illinois are generally divided into 2 based on the modifiers used on the asphalt. They are APP (Attactic Polypropylene) modifieds and SBS (Styrene-Butediene-Styrene) modifiers. In terms of installment, APP membranes are applied with a torch whereas SBS can be applied with either a hot or cool procedure. Both kinds call for the use of reinforcements like polyester and fiberglass mats.

Resilient and economical modified bitumen roofing systems have won a good share of the commercial roof market in the past couple of years. It's a hard and pliable roofing system that's sure to remain. For more information about this type of roofing, you can check out
