Nothing Gets Covered Up
Until It Passes

Measured. Inspected. Signed off — before we call it done.

Quality on a roof isn't a slogan. It's a nailing pattern you can count, flashing you can photograph, and a five-checkpoint inspection sheet we walk with you before the last ladder comes down. Double R Roofing builds every roof in Princeton, WV to the same documented standard — then backs it in writing.

The Checkpoint System

Five Inspections. Every Roof.

A roof fails at the details you can't see after it's finished. So we inspect and document at each stage — before the next layer hides the last one.

01

Deck Inspection

Tear-off exposes the truth. We walk every square foot of decking, replace soft or rotted sheathing, and re-nail loose panels to spec before a single roll of underlayment goes down. You get photos of what we found.

02

Underlayment & Water Barrier Check

Ice & water shield at eaves and valleys, synthetic underlayment lapped and capped correctly, drip edge sequenced under and over where the manufacturer says. This is the layer that saves you in a February thaw.

passed ✓
03

Mid-Installation Review

Halfway through, the crew lead audits the field: nail placement in the nailing zone, shingle offset, flashing at every wall and penetration. Problems get fixed at row twenty, not discovered at year five.

passed ✓
04

Detail & Cleanup Pass

Ridge caps, pipe boots, sealant lines, and ventilation get a dedicated check. Then magnetic sweeps across the yard and driveway — twice — plus full debris haul-off. Your property leaves cleaner than we found it.

passed ✓
05

Final Walkthrough With You

We walk the completed roof line with you, review the photo documentation, register your warranty, and hand over every document. The job isn't done until you've signed off — not us.

What Quality Actually Looks Like

Ridge ventilationBalanced intake/exhaust, calculated

Credentials

Vetted By People Who'd Know

Certifications only matter if somebody with standards is doing the certifying.

Extended system warranties most contractors can't offer

Owens Corning vets Preferred Contractors for licensing, insurance, and installation quality before granting the designation. It unlocks extended warranties on complete roofing systems — coverage that's simply unavailable from uncertified installers.

State of West VirginiaLicensed & Insured

Full liability and workers' compensation on every job

A licensed WV contractor with comprehensive general liability and workers' comp means a crew injury or property incident is our responsibility, never yours. Ask any roofer for their certificate of insurance — we'll hand you ours before you ask.

Manufacturer TrainingOngoing, Every Season

Installation standards that keep pace with the materials

Shingle chemistry, underlayment systems, and ventilation math change. Our crews complete manufacturer training and OSHA safety updates continuously, so the roof you get is built to this year's best practice — not the way it was done in 2005.
