Most people don't give much thought to their roof until a leak or some other problem reveals itself. If you suspect it may be time for a new roof, here are the answers to some typical roofing questions. 

How Long Does A Roof Last?

The typical asphalt shingle roof will last about 20 years. Fiber cement shingles will last approximately 25 years. A metal roof can last 40 years or more. How long a roof lasts can depend a lot on the environment it is in. For example, a roof in the hot desert of Arizona is going to be baked by the sun. The asphalt may dry out and curl before 20 years is up. Wind, snow, hail, sun, and saltwater can all take their toll on roofing material.

Does A Leaking Roof Mean You Need A New One?

Even a new roof can develop a leak if it has been damaged in a storm, but with an older roof, repairs can't go on forever. If your roof has lots of missing shingles and bare spots, spot repairs aren't going to work for long. The damage that can arise from a leaking roof will end up costing the homeowner more in the long run; therefore, it is more cost effective to replace an old roof rather than continue to make repairs.

Does An Old Roof Need To Be Removed First?

The typical home can withstand the weight of two roofs. This means if your house currently only has one roof and it isn't in terrible condition, you can save money by avoiding a complete tear off. However, if you are going to make the switch from shingles to a metal roof, the old roof may need to be removed first.

How Long Does It Take To Get A New Roof Put On?

The amount of time it takes to put on a new roof depends on several factors. If the old roof needs to be taken off, it will take longer. Obviously, the size of the home and how complicated the roofline is will also make a difference. The weather could also play a role. Roofing jobs are usually done during the warmer months when inclement weather is less likely, but summer thunderstorms still occur. This can delay completion as it isn't safe for the roofers to be on the roof during a storm. For most homes, a new roof can be completed within a week.
