A New Roof Won't Fix A Ventilation Problem.

A salesman shows up with a “lifetime warranty” and a $40,000 quote. He never went in your attic.

Most roofs fail from bad ventilation and bad installation, not worn shingles.

Most roofs are replaced before they need to be.

Bad attic ventilation kills more roofs than weather does.

A bad install voids the warranty. Your “lifetime warranty” already means nothing.

What If Someone Checked Everything Before Quoting You?

You shouldn’t need to become an expert in ventilation, flashing, and underlayment just to avoid getting ripped off.

A full inspection

Shingles, flashing, underlayment, attic. Not just the surface.

Honest options

A $500 repair when that is the answer, not a $40,000 replacement you do not need.

Real protection

Third-party insured. If we disappear, you are still covered.

About That “Lifetime Warranty.”

Yes, we offer the same manufacturer warranties everyone does. Here is what they are worth.

Manufacturers pay about 1% of claims. When they do, they ship shingles to your driveway with no labor.

Every roof since 2001 has a “lifetime warranty.” The average roof lasts 8 to 12 years.

The best warranty is the one you actually understand.

Inspect. Diagnose. Fix.

Repair, restoration, or replacement. You choose: Home Guard, Pro Guard, or Elite Guard.

Questions Homeowners Ask Us

Do I really need a new roof?

Maybe not. Most roofs have years left. We tell you the truth, even when it is a repair.

Why is your quote higher than the storm chaser's?

Because we fix the cause, not just the shingles, and we insure the work. Cheap and wrong costs more.

What about my warranty?

Ours is third-party insured. Your coverage does not depend on us still being in business.

Andy came out to assess the workmanship on an in-progress roofing and siding job that was being done on our house and garage by another company. Andy was very forthcoming and patient while listening to our concerns, and he pointed out every issue he found and explained why they were problems and what should have been done to keep with industry standards. He took his time to inspect the work that had been done and also took photos of all issues he found. He was able to give us advice on what we needed to do to protect ourselves and advised that we read through laws and procedures relevant to our project and issues we are facing (he provided information sheets with resources). I feel Andy is very knowledgeable, honest, and takes his job seriously, and I would be happy to work with him in the future.
My account rep was great to work with. He was clearly very knowledgeable and took the time to explain everything and answer all my questions.
I'm very happy and satisfied with my new roof. My old roof was in really bad shape. Andy Wilde was very professional and extremely helpful. He answered all my questions and addressed my apprehension. I explained to him that I had a maximum budget that could not exceed. He worked with me until we could get the cost to where I could manage it. He was great and I was very pleased. The construction crew were outstanding, they were on time, they protected my flowerbeds, yard and driveway. Once done, they cleaned up everything. Hector, was the project manager and he was on site several times to make sure the project was processing as it should and to answer any questions I had as the crew did the installation. All in all, they did a great job and I'm very pleased. I highly recommend them. Job well done.P!
We had a wonderful experience working with Big Fish. After getting several bids from contractors, we decided to go with Big Fish for new windows for our home. Communication throughout the experience was excellent. Paul did a great job explaining the timing and steps involved. The crew at our home were always professional and friendly. We would highly recommend Big Fish for any of your home or window projects.- The Donovan Family
Andy did a great job providing me with a quote for the exterior repairs at my house. He was very friendly and the complete opposite of the pushy salesman. I would recommend working with Andy based on this experience.
