Peace of mind starts with the right roofer

By Corey A. ThrushFirst posted 2020Updated 2026

Peace of mind is the real reason people replace a roof. Not the shingle color, not the brand on the bundle. It’s knowing the roof was done right, the warranty is real, and the company behind it will still pick up the phone years from now.

Most of that comes down to one decision: who you hire. Here are five reasons a GAF-certified, award-winning contractor gives you more protection than the lowest bid, plus a checklist to verify any roofer before you sign.

GAF warranties have your roof covered

This short GAF video explains how a system warranty protects more than the shingles. It’s the quickest way to see why the installer matters.

Then scroll down for the five reasons a certified pro adds real peace of mind, long after the crew packs up.

5 Reasons

Where real peace of mind comes from

The difference between a roof you worry about and one you forget about.

  1. A roof built as one system

    A roof is more than shingles. Underlayment, leak barrier, starter strips, ventilation and ridge caps all have to work together. A GAF-trained crew installs them as one matched system, which is how the roof is designed to perform and how it qualifies for stronger coverage. Done right once, it delivers peace of mind for decades.

  2. Warranty coverage that actually holds

    The best warranty in the world is worthless if the install voids it. GAF-certified contractors can register enhanced GAF system warranties that go well beyond the basic shingle warranty, and they know the accessory and registration rules that keep that coverage valid. That’s peace of mind in writing.

  3. Training that keeps up

    Roofing products and building codes change. GAF requires its certified contractors to keep training, so the crew on your roof knows the current installation details for ventilation, ice dams and high-wind areas, not the way it was done twenty years ago.

  4. A business you can verify

    Peace of mind starts before anyone climbs a ladder. Check that your roofer is licensed where required, carries insurance, has a track record you can look up and answers to someone. Thrush & Son is BBB Accredited with an A+ rating and has been family-owned since 1960.

  5. Recognition you can check

    Awards don’t install roofs, but they tell you who has earned trust over time. Thrush & Son is a GAF President’s Club contractor, one of GAF’s top honors for customer satisfaction and installation quality, and was named Best of Dayton in 2024.

Peace of Mind FAQ

Quick answers before you hire

What homeowners ask us most about choosing a roofer.

What does peace of mind mean when hiring a roofer?

It means knowing the roof was installed correctly, the warranty is real and registered, and the company behind it will still answer the phone years from now. It comes from the contractor you hire as much as the shingles you pick.

What is a GAF President's Club contractor?

The President's Club Award is one of GAF's top honors for residential contractors. It recognizes contractors for high customer satisfaction and quality installation work.

Do GAF-certified contractors offer better warranties?

Yes. GAF's enhanced system warranties are only available through GAF-certified contractors, and the strongest tiers require higher credentials and more qualifying accessories. A basic shingle warranty is available no matter who installs the roof.

How can I check a roofer's credentials?

Ask for proof of insurance and licensing, look the company up with the BBB, read recent reviews and confirm any GAF credential in GAF's online contractor directory.
