As a homeowner, you may assume you know all there is to know about your roof. But there are critical things you should know when it comes to correctly installing and maintaining a roofing system. Check out these eight roofing facts that may surprise you:
1. A Roof is More Than Just Shingles and Wood
A well-made roof system has seven main components. The roof decking supports all the weight of the roof. The ice or water barrier prevents damage in the event of ice damming. You also have a waterproof or water-resistant underlayment that protects the deck from moisture. The metal flashing ensures the water runs properly off the edges. The drip edge provides a similar function. A roof has to be covered in some material, most often shingles. Then there is the ventilation system, comprised of the vents, soffits, and eaves that circulate air.
2. The Type of Roof You Get Depends on Where You Live
Some roof types work better in certain climates and regions. Gable roofs, for example, do best in colder, snowier climates or if you wish to build an attic or include vaulted ceilings.
Hipped roofs are more wind-resistant than their gable counterparts, working best in windier areas. Water pools on flat roofs, so this type will do better in drier climates.
3. Roofs Breathe
Your roof needs air. That’s why it’s so important to have proper roof ventilation, which allows warm, moist air to get into your attic. Without proper ventilation, condensation will build up in your attic, damaging insulation, walls, and wood.
4. You Shouldn’t Cover an Existing Roof
Sure, it looks like an inexpensive, quick fix to your roofing problem, but the truth is, double-layered roofs tend to cover up bigger roofing issues that should be addressed. Also, double-layered roofs add weight and hide the corroding material, making the problem worse.
5. You Shouldn’t DIY a Roof
You may be the handy type who thinks they can fix and replace their own roof, but this is not a good idea. Roofs are complex systems comprised of layers requiring proper installation from skilled professionals. If you try to install or repair a roof, you can damage the roof itself, your attic, wood frame, walls and electrical systems.
6. Faulty Roofs Break a Home Sale
A new roof is a big selling point when selling your home. By the same token, a roof with leaks, damaged or missing shingles, or other signs of disrepair, can turn off a potential buyer who is not keen on shelling out thousands on a costly roof replacement.
7. Some Roofs are Good For the Environment
Environmentally friendly roofs, AKA “cool roofs,” reflect infrared and UV rays away from the home and feature a higher thermal emittance. With a cool roof, you can conserve energy, reduce air pollution and greenhouse gas emissions, and mitigate the heat radiated into the atmosphere.
8. Your Roof Won’t Last Forever
The average lifespan of a roof will depend on the materials and installation. For example, a standard three-tab asphalt shingle roof has a warranty of 20 to 25 years, while shake style shingles have warranties up to 50 years.
