McKinney Roofing: Article About The Benefits Of Shingles
Shingles are a relatively new invention, but the ingredients that make them so useful have been around for centuries. It's hard to believe that modern societies didn't start using asphalt as roof cover until the late 1800s, but this innovation sparked a fundamental shift in the residential construction industry. The main ingredient of shingles is a dense, viscous substance called bitumen, and it's been used in home construction and civil engineering almost as long as people have lived in cities. Today, this material is used to pave roads and make roofs water resistant.
McKinney roofing contractors mainly focus on installing asphalt shingles because 80 percent of North American homes have this type of roof. Bitumen, or asphalt, is popular because it's plentiful, convenient and affordable. Shingle manufacturers have perfected the process of turning it into shingles.
Asphalt was used by the ancient Babylonians to line the man made waterways they used for transportation. Other ancient cultures used it to make baskets waterproof and fill the holes between the stones in their walls. Asphalt has natural waterproofing qualities, but shingles still need help to keep water out of homes. The natural consistency of asphalt is sticky and rock like, and in its fluid state, it pours about as slowly as cold molasses. This high level of viscosity is caused by asphalt's high content of petroleum hydrocarbon molecules.

The close chemical relationship to petroleum also makes asphalt good at repelling water.
Perhaps the biggest benefit of asphalt shingles is their fire resistance. Shingles made with inorganic materials have the highest rating for fire safety, and organic shingles can be made safer by installing them over an aluminum fire shield. In the early 1900s, all shingles were made with organic materials because there weren't any manufacturing methods for creating man made fibers. In this context, organic doesn't mean that the materials were produced without chemical fertilizers; it just means they were once living plant matter. Ingredients like wood and paper are very combustible, and the kind of wood used to make shingles in the old days was especially dangerous.
Fire damage was a major problem in those days, and it didn't begin to improve until technological advances made materials like asbestos and fiberglass easy to manufacture. Of course, it's now known that asbestos is a hazardous substance that causes cancer, but fiberglass has proven to be completely safe. The two key ingredients of shingles, fiberglass and asphalt, make roofs durable, affordable and easy to install. Other ingredients added to shingles, such as metals and mineral granules, make them resistant to UV light, algae and other causes of damage.
