We Started This Company for One Reason
To give homeowners an honest alternative.
The Story Behind the Name
John Mongar spent years watching large roofing companies charge homeowners premium prices for work that should have cost significantly less. The materials were the same. The warranties were the same. The labor quality was often worse. The only difference was layers of overhead — corporate offices, account managers, regional directors — all taking a cut before a single nail got driven.
In 2020, he decided to build something different. Renovation Revelation was founded on a simple principle: deliver the exact same quality — the same manufacturer-certified materials, the same warranties, the same installation standards — at 30-40% less. No corporate markup. No middleman. Just honest work at an honest price.
Since then, the company has grown through word of mouth and repeat business. Homeowners across East Tennessee trust us because we show up when we say we will, we charge what we quote, and we stand behind every project we complete. That reputation is something no amount of advertising can buy.

What We Stand For
Honest Pricing
No hidden fees, no inflated quotes. You see every line item and know exactly what you are paying for. The same materials and warranties as the big companies — at 30-40% less.
Hands-On Leadership
Owner John Mongar is on the job site, not behind a desk. When you hire us, you work directly with the person who built this company.
Built to Last
We use premium materials, follow manufacturer specs to the letter, and never cut corners. Every project gets the same attention to detail — whether it is a small repair or a full replacement.
Insurance Advocacy
When storms hit, we fight for you. We document damage, meet adjusters on-site, file supplements, and make sure your claim gets the coverage your policy guarantees.
