Planning Your New Roof

Everything You Need To Get Started

Before anyone climbs a ladder, you should take a walk through this brief how-to. 
Unless you’re a construction professional, it’s likely this is only your first or second roofing project. There’s no need to feel overwhelmed. At GAF, we believe in making the process as simple as possible.

How do I know if I need a new roof?

Over time, the elements will take their toll on any roof. Paying attention to these danger signals of a failing roof may protect your wallet as well as your home.

  • Attic leaks

  • Blistering or peeling paint

  • Stains on interior ceilings and walls

  • Exterior decay

  • Missing, cracked, or curled shingles

  • Dark, "dirty-looking" areas on your roof

  • Excessive energy costs

What Will My Roof Look Like?

Use one of our preselected homes or upload a picture of your own home to view shingle styles and colors on your house, and find the perfect roof for you.


A new roof is a big investment, typically involving thousands of your hard-earned dollars and lasting 25, 30, 40 years, or more. As with any big investment, knowing in advance what your warranty covers could save you thousands in the event that problems arise with your roof.
