What is it everyone cites as the basic requirement for living? "I'm just glad to have a roof over my head." Yet the matter is often taken for granted, with many homeowners paying little or no attention to the thing overhead that's keep them safe, warm and dry -- until it starts to leak, that is.

Then they notice.

There are dozens of materials commonly used in roofing, all of them functional as well as decorative. Indeed, most people choose their roofing material based on aesthetics or on what their local homeowners association mandates, rather than on what will function best.

Clay tiles (which are often made of concrete, not clay) are known for their durability, often lasting as long as 50 years. They are more expensive, though, which is a deal-breaker for many homebuilders.

A more basic roofing material is the asphalt shingle. They're not particularly attractive, but they do the job. They are particularly good in areas without much rainfall, such as the Southwestern U.S.

Also good in those areas are wood shake roofs, made of many individual pieces of wood that are affixed to the roof. These don't conduct heat as much as some other materials do, so summers are more bearable. (In colder areas, you might not want this kind of roof, as you might want something that WILL trap in heat.)

When roofing repairs need to be done, unless you have experience in that area, it's usually best to call in a professional. Roofing is notoriously backbreaking, arduous work, bad on the knees, back and shoulders. It's also harder to do it right than it may appear, and if your intent is to solve an existing problem, you're better off letting a pro do it and avoid the risk of making it worse by doing it yourself.
