Diagonal Roofing Contractor | Serving Diagonal From Worthington

"Their crew showed up at 7 AM, tore off the old roof, replaced eight sheets of plywood, and had new shingles down before dinner. Jobsite was cleaner when they left than when they arrived."

"Second roof Worthington Roofing & Maintenance has done for us. First one on our primary home, now our rental property. Same crew both times, same attention to detail. Drip edge, ice shield, everything by the book."

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

Storm Damage Specialists

Hail, wind, and monsoon damage are common in IA. Our team includes HAAG Certified inspectors who document damage the way adjusters expect it. We handle the entire insurance claim process so you don't have to.

23+ Years of Experience

We've been installing and repairing roofs for over 23 years. That experience shows in how we handle complex roof lines, unexpected deck damage, and insurance claim disputes. We've seen everything and know how to handle it.

No Subcontractors

Every Diagonal roof is installed by our own trained crews, not subcontractors pulled from a labor pool. That means consistent quality, accountability, and a crew that knows our standards from the first nail to the last drip edge.
