How Do Roofs Actually Protect Homes?

Posted on: 18 November 2022

Roofers will often tell you that it's important to have a solid, intact roof in order to protect your home. This is true, but it is not very specific. If you're considering getting a new roof or wondering why roof repairs are so important, it is helpful to understand how, exactly, a roof protects your home. Below, you'll learn more about the key ways in which a roof protects your home.

Protection From Water

Without a roof, whenever it rained, your home would get quite wet inside. But what you may not realize is just how water-tight a roof must be to do this job effectively. Even if a roof only has a small leak, that leak can let in enough water to damage insulation, allow mold to grow in the attic, and allow rot to begin developing in the attic trusses. 

Roof leaks are not always due to missing shingles or tiles, either. Often, they are caused by lifted or peeling flashing or improperly installed roof vents. As such, you should periodically check your attic for signs of moisture even if your roof appears to be intact.

Protection From Heat

When it's summer and the sun is shining, your roof protects your home from that heat. A good roof will prevent the top floor of your home from getting too hot, which will keep your air conditioning bills in check. The lighter the color of your roof, the cooler it will keep your home, as cool colors absorb less heat.

Sometimes, as shingle roofs become older, they offer less protection against heat. The granules, which are reflective, start falling off the shingles. So, if your AC bills are rising, this could mean it's time to consider a roof replacement.

Protection From Cold

Similar to how they protect against heat, roofs also protect against the cold. The better insulated your roof is, the more protection against cold it will offer. If the top floor of your home always feels chilly in the winter, consider asking a roofing contractor to add more insulation to your roof. 

A good roof also protects against the sort of precipitation you get during cold weather, which is snow. Shingles that are intact and well-sealed to the roof deck are less likely to be lifted by snow or ice.

Hopefully, this article has given you a clearer idea of how roofs protect your home. If you have any questions or are worried your roof is no longer offering adequate protection, contact a roofer near you.
