You see a leak. You feel a draft. You see aging shingles. Why is a salesman pitching a $50,000 decision?

Premature replacement

Most roofs are replaced before they need to be. You may not need a new roof at all.

Misdiagnosis

That draft you feel? Most of the time, it's not a window problem. But the window guy won't tell you that.

Wasted money

You pay for a new roof, but the leak is from a window. We diagnose the actual problem so you only pay for the work you need.

You should be empowered, not sold.

Buy it wrong, buy it twice. We see it every week: homeowners paying us to fix what should have been done right the first time.

You shouldn’t need a construction degree to avoid getting ripped off. You shouldn’t have to become an expert in flashing, ventilation, and building envelope science just to fix a leak.

That’s our job.

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.
I received 03 quotes and chose Guardian. Nick was great to work with. He kept me informed of what was going on throughout the job. The crew worked very hard and did excellent work. I would not hesitate hiring Guardian again for future projects.
Excellent work from the Guardian crew sent out to assess a leak! Tommy, Drew, and Josh were all professional and helpful. They took the time to see the leaking spot from several angles before coming up with two thorough plans to address the issue. The repair held through a week of severe thunderstorms, excess rain, and tornadoes. I couldn't be happier with the communication, repair, and service provided by these three gentlemen!
Andy was very detailed, answered all my questions, and made getting our roof repaired very stress free. He has great customer service skills. Just around a great person thank you Andy

Roofing. Windows. Siding. Done Right.

ROOFING

Asphalt, metal, or specialty.

Most roofs are replaced prematurely. We’ll tell you if yours requires replacement, or if a simple repair could add another decade.

WINDOWS

Certified window specialists.

Drafty windows are rarely the real problem. We diagnose what’s actually letting the cold in — and fix it at the source.

SIDING

Built to last, not just to sell.

Full siding replacement when you need it. Targeted repair when you don’t. We’ll tell you which this is.

Pay for Your Home Like You Pay for Your Car

Here’s the biggest misconception in home improvement: You need $20,000 in the bank to start. You don’t walk into a car dealership with a suitcase of cash. Why would you do that for your roof? We build a plan around your budget.

Keep your savings

We can often get you pre-qualified for a full project without touching your emergency fund.

The "Smart Way" to Pay

Maybe we complete the roof, windows, and siding together for one low monthly payment — or maybe we just fix the urgent leak now.

No square pegs

We don't have a 'one-size-fits-all' agenda. We have a solution that fits your life.

Don’t wait until the damage gets worse. You might be able to get a brand-new-looking house right now for a monthly payment you didn’t think was possible.

The "No Sales Guy" Zone

Most companies send a salesperson to sell you. We send a Home Advisor to help you. That means you get an expert diagnosis and a clear path forward, not a sales pitch.

Ready to Fix It Right the First Time?

Most homeowners overpay because they don’t get the right diagnosis first. Let us change that.
