Ventilation, Warranty, and Roof Life: A Landmark PRO Resawn Shake Roof in Cumberland

Most homeowners choose a roof by its shingle and its color. What actually determines how long that roof lasts — and whether its warranty even holds — is something you never see from the street: the ventilation underneath it. This Cumberland home got both done right, a heavier-weight CertainTeed Landmark PRO roof in Resawn Shake built over a balanced ridge-and-soffit ventilation system engineered to carry the roof to its full rated life. Pinnacle roofs go on fast — often as a one-day roof replacement — and flexible financing keeps a project like this within reach, with plans as low as 0% interest for 18 months.

A new CertainTeed Landmark PRO roof in Resawn Shake was installed over a balanced ridge-and-soffit ventilation system in Cumberland, the combination that protects both the roof’s lifespan and its manufacturer warranty. This project is in Cumberland, Rhode Island, finished in CertainTeed Landmark PRO — Resawn Shake.

Scope of Work

The re-roof started with the part most crews treat as an afterthought and Pinnacle treats as the foundation: the ventilation. Intake was confirmed and opened at the eave soffits so fresh air can enter low, and a continuous ridge vent was set at the peak so warm, moist air exhausts high — the balanced system that keeps air moving through the attic year-round. On top of that went the full weather system: CertainTeed WinterGuard ice-and-water shield along the eaves and up the valleys, DiamondDeck synthetic underlayment across the field, and new drip edge and starter courses. The Landmark PRO shingles in Resawn Shake were coursed up the slopes and finished with matching hip and ridge caps set over the ridge vent, so the peak exhausts along its full length while the finished roof reads as a clean, continuous field. On a wooded inland lot like this one, where shade and damp hold moisture against a roof, that constant airflow is what keeps the deck dry and the shingles aging on schedule instead of early.

What We Installed (And Why)

This roof pairs a premium shingle with the ventilation that lets it reach its full life. CertainTeed Landmark PRO is the heavier-weight member of the Landmark family — a dual-layer architectural shingle with more mass than standard Landmark, rated to 130 mph winds, carrying a Class A fire rating, Max Def color depth, and StreakFighter algae resistance, and installed to a specification that qualifies for CertainTeed’s strongest SureStart PLUS warranty coverage. Its Resawn Shake color is a warm, weathered wood-tone blend that gives the home the look of a natural shake roof with none of the upkeep. But here is what most homeowners are never told: that manufacturer warranty depends on ventilation. Shingle makers require a balanced ventilation system for their full coverage, because an unventilated attic bakes the shingles from below in summer and traps moisture against the deck in winter, aging the roof years before its time — and a roof that fails early because it could not breathe is not a warrantable defect. A balanced ridge-and-soffit system prevents all of that: cool air enters at the eaves, washes up the underside of the deck carrying away heat and moisture, and exhausts at the ridge, keeping attic conditions close to the outside air in every season. On a shaded, wooded Cumberland lot, where a roof stays damp longer and moss and moisture press against the north slopes, that continuous drying is exactly what protects both the shingles and the deck beneath them. Ventilation is not the glamorous part of a roof — but it is the part that decides how long the roof lasts and whether its warranty stands behind it.

Good To Know: Does my roof warranty actually depend on ventilation?

Yes — and it is one of the most overlooked facts in roofing. Shingle manufacturers require a balanced attic ventilation system for their full warranty coverage, and for good reason: ventilation is what keeps the roof from destroying itself from the inside. An unventilated or poorly ventilated attic superheats in summer, and that trapped heat bakes the shingles from below, prematurely aging the very shingles the warranty is supposed to protect. In winter, the same dead-air attic traps moisture that condenses on the cold deck and rots it. A roof that fails early because it could not breathe is not treated as a manufacturing defect — so the coverage that looks like decades on paper can quietly be voided by the one thing you cannot see. A balanced ridge-and-soffit system is the requirement and the protection at once: intake low at the eaves, exhaust high at the ridge, and a continuous flush of air that keeps the attic near outdoor conditions in every season. Building it correctly is what keeps a manufacturer warranty fully in force and, just as importantly, lets the roof actually reach the lifespan that warranty promises.

Why This Approach Works

A roof is a system, and its lifespan is set as much by the airflow underneath the shingles as by the shingles themselves. A balanced ridge-and-soffit ventilation system keeps the attic from overheating in summer and trapping moisture in winter — protecting the deck, the shingles, and the manufacturer warranty that stands behind them.

Why Pinnacle

Building the ventilation to the manufacturer’s specification, not just the shingles, is what protects both the roof’s life and its warranty. As a CertainTeed ShingleMaster™ Premier contractor, Pinnacle qualifies our customers for CertainTeed’s full SureStart™ PLUS extended warranty — coverage most contractors cannot offer.

Cumberland, Rhode Island

Cumberland sits in Rhode Island’s northeast corner, a town of wooded neighborhoods, older homes, and mature tree cover that shades many roofs for much of the day. That shade is pleasant to live under but hard on a roof — a shaded roof stays damp longer, holds moisture and moss, and asks even more of its ventilation to stay dry. A Landmark PRO roof built over a properly balanced ridge-and-soffit system is well matched to Cumberland’s conditions, giving a home a premium roof that is set up to reach its full life rather than aging early in the shade.
