"I'm a contractor and I use Grantham Roofing & Maintenance for all my roofing subs. Their installs pass inspection every time. Their crew lead has been doing this 20+ years and it shows."

"Couldn't believe how clean the job site was when they left. Three passes with the magnet, swept the driveway, cleaned the gutters out. My wife said the yard looked better than before they showed up."

"Asked for a second opinion because another company said I needed a full replacement. Grantham Roofing & Maintenance said I only needed valley flashing repair and some shingle replacement. Saved me about $14,000. I trust these guys."
