If you have an asphalt shingle roof in FL most likely it's suggested to be replaced before it leaks. Think about the nice black top asphalt road when it's first put down. It is black right, after a short time it starts to grey out because there is nothing protecting it from the sun. So if you have an asphalt roof and it's exposed to the sun it's going to dry out loose it's wic or flexability and become non-pliable. At this point repairs are unable to be made and you would damage more shingles then you would need to repair. There is also seal strips under the shingles that dry out as well then the shingles will start to curl up or down (fish mouthing or bear clawing) either way at seventeen years you should start looking instead of waiting until it's starts to leak. Do you wait tell the brakes on your car stop working or until it doesn't run because you didn't put gas in it. It's called prementative maintaince. Just like having your a/c serviced once a year. Your roof protects all your belonging (or most of them) and replacing before it leaks saves you money by not having interior repairs. I hope this helps you, remember to alway do as much research as you can on your contractor. Check them out up and down before you make your final selection.

Because of the constant baking sun and frequent wetting (from the afternoon thunder showers) in Florida and relatively high heat, the life of a shingle (or almost any roof) is going to be shortened. If you did not walk on it at all, it would probably make it to its advertised life okay, as far as shedding water and such.

The primary problem comes with those little nuisances you people have down there called hurricanes and tornadoes. Once the shingle is brittle, it cannot flex and bend when hit by a particularly direct gust of wind - it will crack off or split or pull free of the nails instead. Also, the tabbing (strip of asphalt near the tip intended to hold shingle down to the one below it) really does not work at all well, so unless your shingles were installed with individual tabbing of each shingle tab with bitumastic cement (which adds quite a few hundred $ to installation cost), then their resistance to wind uplift will be severly dimished after about 15 or so years of service.
