Most roof replacements cover 20 or 30 squares. This one covered nearly 83. When the owner of a large single-story property in the Hillsville area near Blacksburg, Virginia noticed a couple of active leaks — along with signs of possible hail and wind damage — they called our New River Valley roofing team for help. What followed was one of the more substantial residential-style replacements we take on: a full tear-off and rebuild across a sprawling, cut-up roof.
A project at this scale isn't just a bigger version of a normal job — it's a logistics and craftsmanship challenge that rewards experience. Here's how our crew handled it.
The owner suspected hail and wind had taken a toll, and a couple of leaks had already appeared. Hail can bruise and fracture shingles in ways that aren't always obvious from the ground, while wind lifts and creases shingles until the seal breaks and water finds its way in. Once leaks show up, it usually means the damage is no longer cosmetic. Rather than chase individual leaks across a roof this size, a full replacement was the sound long-term call — and the ideal moment to correct any underlying issues before rebuilding.
If you suspect storm damage to your own roof, a professional roof inspection is the right first step to understand what you're actually dealing with.
To put this roof in perspective: it measured 82.78 squares — roughly five times the size of an average home's roof — spread across a complex layout with 145 feet of ridges, 72 feet of hips, and 50 feet of valleys. There were 340 feet of eaves to detail, 250 feet of rakes, seven plumbing penetrations to seal, and multiple crickets to build to divert water around obstructions.
A roof with this many valleys and transitions is essentially dozens of smaller roofs stitched together, and each junction is a place water wants to get in. Handling that volume of detail work correctly — over a multi-day install — is exactly where the experience of our Virginia roofing crews earns its keep.
The property owner chose Owens Corning TruDefinition Duration architectural shingles in a bold Onyx Black. These 50-year shingles use Owens Corning's SureNail Technology for excellent wind resistance — a fitting choice for a roof that had already seen what the weather could do.
The complete system installed on this property included:
On a roof this large, attic ventilation matters more than ever. Our crew installed 155 feet of OC VentSure ridge vent, working with the roof's long ridge lines to exhaust hot, moist air continuously. Proper ventilation protects the new deck from moisture buildup, helps regulate temperatures, and extends the life of the shingles — protecting the substantial investment this roof represents.
This roof is protected by the Owens Corning System Protection manufacturer's warranty on materials, backed by Cenvar's workmanship warranty, transferable if the property changes hands within the covered window. As with every Cenvar project, the owner paid $0 down with nothing due until the job was complete and they were satisfied, with financing available for those who want it.
