9 Out of 10 Wisconsin Roofs Are Replaced Before They Need to Be.

You see a leak. You feel a draft. A salesman’s already at your door with a $40,000 quote. Here’s what nobody is telling you…

!

Most roofs are replaced before they need to be

An aging roof can usually be repaired or restored — saving you tens of thousands.

!

Most "leaks" aren't roof problems, they're attic / flashing problems

Without a real diagnosis, you'll pay to replace something that wasn't broken.

!

Most "lifetime warranties" are voided by bad installation

Improper installation invalidates manufacturer warranties — and the contractor is long gone.

What If Someone Found the Actual Cause Before Quoting You a Dollar?

You shouldn’t need to become an expert in ventilation, flashing, and underlayment just to stop a leak without getting ripped off.

Get a real diagnosis

We inspect your shingles, underlayment, flashing, and attic ventilation — not just the surface. Our Certified Home Advisors use the same inspection protocol taught to Wisconsin’s home inspectors for continuing education credits. If the problem is in your attic, we’ll find it.

Get unbiased repair options

We’re certified with every major manufacturer. No exclusivity agreements. No commissions on specific products. We recommend what you actually need — even if that’s a $500 repair instead of a $40,000 replacement.

Get real protection

Most “lifetime warranties” have so many exclusions they’ll never actually pay out. Ours is backed by third-party insurance. That means even if Guardian disappeared tomorrow, you’re still fully covered. By an actual insurance company. With actual money.

Get permanent results, not a patch job

We don’t do temporary fixes. Every Guardian repair is engineered to solve the root cause permanently. We ask a few simple questions about your goals and timeline, then match the right solution to your life — short-term fix, medium-term fortification, or long-term replacement.

Get the Right Fix, Not a Sales Pitch

We examine your roof, attic, ventilation, and entire building envelope — not just the shingles.

1

Inspect.

We examine your roof, attic, ventilation, flashing, and entire building envelope — not just the shingles. We use infrared scanning to find hidden moisture and air leaks that visual inspections miss. This is the same process Fortune 500 companies hire our consulting division to perform.

2

Diagnose.

We tell you what’s really causing the problem — and what isn’t. You’ll get a written report with photos showing exactly where the issue is and why. Even if the diagnosis means we don’t make a sale, you’ll know the truth.

3

Fix.

We present repair, restoration, or replacement options — matched to your goals and budget. Short-term, medium-term, or long-term. Every option priced transparently. You decide on your own time. No pressure, no expiring discounts, no “today only” games.

Don’t Let Your Roof Get Worse While You Save Up

Most homeowners wait months — sometimes years — to fix roof problems because they assume they’ll need thousands of dollars in the bank. Meanwhile, the $800 repair turns into a $5,000 problem. The water damage spreads. The mold starts. The energy bills climb. That wait is a myth.

$

Fix the urgent problem first

We tackle the active leak now and phase in any additional work over time. Stop the bleeding today, plan the rest on your schedule.

$

Simple monthly payment

Bundle the whole repair into a payment you can budget for. Plans starting as low as $29/month. No surprises, no balloon payments.

$

Protect your cash

Keep your savings for an actual emergency. Use our “Smart Way to Pay” to get the repair done today without draining your bank account.

4.8 - star rated by 530+ happy customers

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.
