What is the Expected Lifespan of My Roof?

The expected lifespan of any average roof system is around 18 years. Most people do not perform any preventative maintenance or cleaning, therefore causing their roof to deteriorate sooner than later. Basic roof maintenance, such as washing, clearing, and cleaning the gutters and other roof debris can prevent re-roofing to early, and most usually will be more beneficial than the cost to do so.

Although caution must be taken seriously. Today most building insurance and homeowner insurance policies heavily depreciate your roof, starting at year 10. This could be very costly for you.

These materials will be transformed into high quality durable roofing shingles and specialty products that have earned the respect of countless industry professionals and homeowners.

Shingles made with asphalt as the main ingredient are the most popular shingles sold in the U.S. today, and so the asphalt used at these roofing facilities is processed to meet the stringent quality requirements needed to create strong, yet flexible, shingles.

Limestone rock, which typically arrives at plants by truck or rail car, is processed by crushing mills into a fine limestone powder. This powder is then mixed with the asphalt to make a product called filled coating. On the production line, miles upon miles of rolled fiberglass mat that serves as the ‘backbone’ of shingles are rolled out and fed into a coater, where the filled coating – super-heated to more than 400 degrees Fahrenheit – is applied to the top and bottom of the mat to create a base sheet.

Next up come the shingle granules. Mined rock that has been sized for use as granules is put through a process where a specialty ceramic coating is applied. The coating is colored so that the granules create the desired shingle colors, and these granules are designed to maintain their appearance for the life of the shingle. A thin coating of sand is applied to the base sheet as it is fed into a press that embeds the granules. As the sheet loops through a series of rolls, a fine mist of water is sprayed onto it, and the evaporative effect of the water removes heat from the sheet. Afterward, a strip of sealant is applied to the sheet in order to give the shingles protection against wind damage.

Complex cutting machines then slice the base sheet into individual shingles that are stacked and packed into bundles. Finally, the shingle bundles are wrapped in packaging, placed onto palettes, and then transported to warehouses prior to being shipped to homes just like yours all across America!
