Peck Roofing Contractor | Serving Peck From Grenola

"Had a bad leak around the chimney flashing after a storm. Grenola Roofing & Maintenance came out next day, found the failed step flashing, replaced it, and sealed everything properly. No more dripping. Solid work."

"Hail punched through half our shingles last spring. Grenola Roofing & Maintenance handled the entire insurance claim — met the adjuster, filed the supplement, and we paid nothing out of pocket besides the deductible."

"Our flat roof on the garage had been patched five times by other companies. Grenola Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
