A roof replacement is one of the most valuable investments you can make — it adds curb appeal to your home and keeps your family and possessions protected from the harsh elements. But like many other construction projects, doing it right requires time and preparation. If the time has come for your rooftop makeover, read our guide to learn what a roof replacement involves and how to best prepare for it. Even if you think you need a roof replacement, sometimes a simple repair is all that’s necessary. For instance, if you just lost a few shingles in a severe storm, but the rest of the roof is sound, a repair is probably the more efficient solution. You will likely only need a repair if your roof is 15 years old or younger.
