CertainTeed Landmark Charcoal Black Roof Replacement with Deck Repair in Coventry, RI

Like most Pinnacle roofing projects, the work was completed in a single day — minimizing disruption for the homeowner.

Pinnacle makes every roof affordable with monthly financing options, including 0% interest for 18 months.

Not every roof replacement reveals what this one did. When our crew stripped the old shingles off a home on Lear Drive in Coventry, RI, we uncovered severely rotted roof decking — sections of the original plywood had absorbed moisture for years through failed underlayment, leaving the sheathing spongy and structurally compromised. The homeowner had noticed curling shingles and minor ceiling stains but had no idea the substrate beneath was deteriorating. As a CertainTeed SELECT ShingleMaster, Pinnacle Roofing handled the full scope: tear-off, deck repair, and a complete new CertainTeed Landmark roof system in Charcoal Black — a color that provides bold contrast against the home’s white and red trim while delivering the dimensional depth CertainTeed’s Landmark line is known for.

Scope of Work

The project began with a full tear-off of the existing asphalt shingles across the entire roof surface, including all hip caps and ridge material. As each section was stripped, our crew inspected the plywood decking inch by inch. The southeast-facing slope showed the worst damage — multiple sheets of plywood had delaminated from prolonged moisture intrusion where the old felt underlayment had failed at the seams. We removed and replaced all compromised decking with new 7/16″ CDX plywood, ensuring a solid, code-compliant substrate for the new roof system.

With the deck restored, we installed CertainTeed WinterGuard ice and water shield along all eave lines, valleys, and around the chimney flue penetration. The entire remaining deck received CertainTeed DiamondDeck synthetic underlayment — a breathable, non-slip membrane that outperforms traditional felt in every measurable category. New aluminum drip edge was installed at all eaves and rakes. We applied CertainTeed SwiftStart starter strips at the eaves and rakes to establish the critical first line of wind resistance, then laid the Landmark field shingles in a staggered pattern following CertainTeed’s recommended 5-inch exposure. Every pipe boot was replaced with new neoprene-collared boots, and the chimney received new step flashing and counter flashing to seal the roof-to-masonry transition. The project was completed with CertainTeed Shadow Ridge hip and ridge caps for a clean, finished ridgeline with enhanced ventilation.

What We Installed (And Why)

The homeowner selected CertainTeed Landmark architectural shingles in Charcoal Black — a versatile, high-contrast color that pairs well with the home’s existing siding and adds strong curb appeal from the street. Landmark shingles carry a Class A fire rating, 110 mph wind resistance, and CertainTeed’s proprietary StreakFighter algae-resistance technology, which prevents the black streaking that plagues roofs in New England’s humid summers.

What makes the Landmark system perform is how every layer reinforces the next. CertainTeed’s Integrity Roof System pairs the ice and water shield, synthetic underlayment, starter strips, field shingles, and ridge caps as a tested, warrantied assembly — not a collection of individual products from different manufacturers. When all components come from CertainTeed’s system, the homeowner qualifies for enhanced warranty coverage that a mix-and-match approach cannot provide. According to CertainTeed’s installation specifications, proper starter strip placement along eaves and rakes is essential to achieving the published wind resistance ratings — without it, the first course of shingles is vulnerable to uplift in the exact zone where wind pressure is highest. That is why Pinnacle installs SwiftStart on every roof, not just as a best practice but as a manufacturer requirement for full warranty activation.

Good To Know

This Coventry project is a textbook example of why full tear-off beats overlay every time. Rhode Island building code allows a second layer of shingles over an existing roof, and some contractors push this as a cost-saving shortcut. The problem is obvious when you see what lies beneath — the only way to inspect the deck, replace damaged plywood, and install a proper ice and water shield is to strip the roof down to bare wood. On this Lear Drive home, the rotted decking would have been completely hidden under a second layer, allowing moisture damage to spread until a section of roof literally failed. Coventry sits in central Rhode Island where snowfall averages 35 inches per winter, and freeze-thaw cycles are relentless from November through March. Every ice dam, every wind-driven rain event pushes water into any gap the old system left behind. A full tear-off costs more upfront, but it is the only approach that gives your contractor — and you — a clear picture of what the roof structure actually needs before a single new shingle is nailed down.

Why This Approach Works

Replacing the compromised decking before installing new shingles is not optional — it is structural. A shingle roof system transfers wind loads through the nailing pattern into the plywood deck and down into the rafters. When that deck is delaminated or spongy, nails lose holding power, and the entire wind resistance rating of the shingle system is compromised. By restoring the deck to solid CDX plywood and building the CertainTeed Integrity Roof System from the substrate up, this roof will deliver its rated 110 mph wind resistance and the full manufacturer warranty for decades.
