Strong Foundation for a Lasting Roof

Your roof decking—the plywood or OSB sheathing nailed to your rafters—is the foundation everything else depends on. Shingles, underlayment, flashing: none of it matters if the deck beneath is rotted, warped, or improperly fastened.

At Roff Roofing & Renovations, we treat decking work with the seriousness it deserves. When we tear off an old roof, we inspect every square foot of deck. If we find soft spots, water damage, or code violations, we replace those sections with properly rated material, fastened to manufacturer specs.

We've been serving New Jersey homeowners for years, and we've seen what happens when decking is ignored or patched poorly. Sagging rooflines. Nail pops. Premature shingle failure. We won't let that happen on our watch.

Whether you're getting a full roof replacement or repairing storm damage, we make sure your decking is square, solid, and built to last. No shortcuts. No surprises.

Why Decking Matters

Most homeowners never see their roof deck—but it's doing all the heavy lifting. It carries the weight of your roofing materials, transfers loads to the framing, and provides the nailing surface that keeps everything in place during wind events.

If your decking is compromised, your entire roofing system is at risk. That's why we never skip the inspection step, and why we're upfront about what needs replacing before we start the job.

How it works

Tear-Off & Inspection

We remove old roofing materials and carefully inspect every section of existing decking for rot, warping, or fastening issues.

02

Replace Damaged Sections

Any compromised decking is removed and replaced with code-compliant plywood or OSB, properly sized and fastened to your roof framing.

Prep for Roofing

We ensure the deck is clean, level, and ready for underlayment and shingles, with proper drip edge and ventilation details in place.

Common questions
How do I know if my roof decking needs replacement?+

You won't know for sure until the old shingles come off. We inspect the deck during tear-off and document any soft spots, water stains, or structural issues. If replacement is needed, we'll show you exactly what we found and explain the scope before proceeding.

What type of decking material do you use?+

We typically use 7/16" or 1/2" OSB or CDX plywood rated for roof sheathing, depending on your rafter spacing and local code requirements. All materials meet or exceed NJ building standards.

Is decking replacement included in a roof replacement estimate?+

Our estimates include a reasonable allowance for decking replacement based on the age and condition of your roof. If we discover more damage than expected during tear-off, we'll notify you immediately with photos and a revised cost before proceeding.
