There’s nothing quite like a fresh roof to transform the curb appeal of a home. But don’t just take our word for it - here’s what this Morris County homeowner had to say: “I can’t say enough good things about Cesar and his crew. They came on time every day, were meticulous, friendly and courteous and did a fantastic job on the roof. They answered every question I had and they actually cleaned up every evening before they left including taking tarps and ladders so my home did not look like a disaster zone. After the job was done Cesar actually came back after the workers left and I was so surprised to see him walking the property again to ensure any and all waste was disposed of properly. I would highly recommend both Cesar and George J Keller for your roofing needs.”

We talk about being Master Elite Certified and 3-Star President’s Club a lot—but what does that actually mean for you?
1️⃣ Top 2%: Only 2% of roofers nationwide qualify for Master Elite status. Less than 1% have earned the 3-Star President’s Club award.
2️⃣ Best Warranties: We can offer GAF’s strongest, longest-lasting warranties that standard roofers cannot.
3️⃣ Proven Excellence: The 3-Star President's Club means we consistently hit the absolute highest marks in performance, reliability, and service.
When you are making a large investment to protect your home for decades, you deserve to have it handled by someone with a track record of knowledge and quality: that’s what we are here for.

May the Force be with you today! ⚔️✨ But when the force of Mother Nature strikes, your roof shouldn't need a Jedi to protect it - but you DO need a Certified GAF Master Elite roofer and GAF Timberline HDZ® shingles.

*130 mph wind rating (That’s Category 3 hurricane force!)
*LayerLock® Technology for an asphalt-to-asphalt bond that won't quit
*Infinite Windspeed Protection — With the WindProven™ Limited Wind Warranty, there is NO maximum wind speed limit!
