Although we often take roofing for granted, they’re one of the most important features of our residences. Without them, rain would readily fill our floors and quickly soak all of our belongings, hail could quite literally kill people in the “comfort” of their own homes, and birds could drop excrement bombs into our living spaces without a single silk thread’s worth of protection.
What are roofs made of?
The vast majority of modern roofs are made primarily of asphalt shingles. Asphalt, also known as tar, is combined with rocks, ceramic, sand, mica, talc, and fiberglass – other materials are sometimes used in America’s favorite roofing material – and molded into sheets roughly two feet long and one foot wide.
When homes are built, pieces of plywood, a thick, sturdy type of composite building material that consists of compressed wood chips. Above this material, which effectively serves as the musculoskeletal system – “musculoskeletal” is a fancy medical term that refers to the body’s skeleton and network of muscles – of roofs, is tar paper.
Also made out of asphalt, tar paper is a thick, paper-like material that is secured to the plywood skeletons of modern roofs. Tar paper is waterproof and is meant to be overlapped and firmly secured by builders to prevent water from finding its way into the structure of roofs, a gaffe that would unarguably cause serious structural damage to the plywood that serves as the bones of modern roofs.
How long do most modern roofs last for?
Different types of roofing materials make for variation in terms of how long different modern homes’ roofs last for. However, when it comes to asphalt shingles, most homeowners, as long as they live in mild to moderate climates, can expect their asphalt shingles to hold up for roughly 20 years, says U.S. News & World Report.
Different types of roofs, such as metal roofs, can last upwards of <i>50 years</i> if they’re treated properly and not exposed to many years of harsh, winter weather.
Homeowners who live in the harsher climates that the United States has to offer, such as those in Montana, North Dakota, or Wyoming, are much more likely to be forced to replace their roofs in their entirety in 10 to 15 years, though such roof lifespans also vary based on how well they were built in the first place and whether their homeowners take care of them after each winter season or not.
No matter how you look at it, roofs are integral to the structural integrity of homes and must be intact to provide people with protection from Mother Nature and the outside world.
Here are a few reasons to get new roofing
If you recently had a storm blow by your house, you can potentially get an insurance company to pay for a new roof – as long as you’re covered, that is.
According to J & K Roofing experts, roofs that are exposed to a few years’ worth of unusually harsh weather also need to be replaced in some cases.
Roofs that weren’t built well in the first place will need to be replaced very soon after installation.
