The roof has survived its lifespan. Moss, mold and mildew have taken hold. Masks, gutter protectors or fascias are missing. If your roof is 15 years old, you'll need to change it within 5 to 8 years.
So start budgeting for it now. Call a contractor for an inspection and get an estimate of the roof replacement to get an idea of how much you'll need to save when the time comes.

One of the first things to consider before starting to inspect your roof for cracks, breaks, and other problems is how old it is. A roof that is 25 to 30 years old or older may require a complete replacement, even if the roof itself appears to be in good shape to the naked eye. If you're close to 20 and you know you're going to sell your house in 2 to 5 years, you'll probably need to replace the roof to put your house on the market.
