How Roof Ventilation Cuts Summer Cooling Costs: A Block Island Re-Roof

Roof ventilation is usually sold as protection for the roof, and it is — but it also does something a homeowner feels every summer in their comfort and their cooling bill. This New Shoreham home on Block Island got a new CertainTeed Landmark Premium roof in Cobblestone Gray built over a balanced ventilation system that keeps the attic from turning into a furnace that the air conditioning has to fight. 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 Block Island (New Shoreham) home was re-roofed in CertainTeed Landmark Premium in Cobblestone Gray over a balanced ventilation system that vents summer attic heat, easing the load on cooling and lowering energy costs. This project is in New Shoreham, Rhode Island using CertainTeed Landmark Premium — Cobblestone Gray.

Scope of Work

The re-roof paired a premium shingle with the ventilation that keeps a house cooler in summer. Intake was opened at the soffits and exhaust set high so the attic can flush out the intense heat it collects under the summer sun. The full weather system went down and the Landmark Premium shingles in Cobblestone Gray were coursed up the slopes on this exposed island home. By keeping the attic near outdoor temperature instead of letting it superheat, the ventilation keeps that heat from radiating down into the living space and driving up the cooling bill.

What We Installed (And Why)

Most people think of attic ventilation as protecting the roof — and it does — but it also directly affects how hot the house gets and how hard the air conditioning has to work. On a sunny summer day, an unventilated attic becomes an oven: the sun heats the roof, the roof heats the trapped air beneath it, and an enclosed attic can reach well over 140 degrees. That superheated air does not stay put. It radiates down through the ceiling into the living space below, warming the top floor and forcing the air conditioning to run longer and harder to keep up — which shows up as higher energy bills and a house that never quite cools off upstairs. Balanced ventilation breaks that cycle. With intake low at the soffits and exhaust high on the roof, the attic continuously flushes its hot air out and pulls cooler outside air in, keeping the attic far closer to the outdoor temperature instead of letting it bake. A cooler attic means far less heat pressing down into the rooms below, so the air conditioning cycles less and the upstairs actually stays comfortable. On an exposed, sun-and-wind-swept island home like this one on Block Island, that summer heat load is real, and the ventilation earns its keep every warm day. The roof itself is CertainTeed Landmark Premium in Cobblestone Gray, a heavyweight architectural shingle for a demanding coastal setting — but it is the ventilation beneath it that turns down the summer heat. Protecting the roof is the headline benefit of ventilation; a cooler house and a lower cooling bill are the ones the homeowner feels.

Good To Know: Can roof ventilation really lower my cooling bill?

Yes — it is one of the most tangible everyday benefits of good attic ventilation. On a sunny summer day, the sun bakes the roof, the roof heats the air in the attic beneath it, and an enclosed, poorly ventilated attic can climb well past 140 degrees. That superheated air does not simply sit up there; it radiates down through the ceiling into the rooms below, warming the top floor and making the air conditioning run longer and harder to hold the temperature. The result is higher cooling bills and an upstairs that never quite feels comfortable. Balanced ventilation changes the math: with intake at the soffits and exhaust high on the roof, the attic continuously vents its hot air and draws cooler outside air through, keeping it much closer to the outdoor temperature rather than letting it turn into an oven. A cooler attic means far less heat pushing down into the living space, so the air conditioning cycles less often and the house cools more easily. It will not replace air conditioning, but it meaningfully reduces the load on it, which shows up as lower summer energy use and a more comfortable top floor. This is on top of ventilation’s main job of protecting the roof and deck from heat and moisture damage — so the same balanced system that extends the roof’s life also makes the house cheaper to cool. On an exposed island home like this Block Island house, where summer sun is intense, that comfort-and-cost benefit is felt every warm day.

Why This Approach Works

An unventilated attic superheats in summer and radiates that heat down into the living space, forcing the air conditioning to work harder. Balanced ventilation flushes the hot air out and keeps the attic near outdoor temperature, easing the cooling load and lowering summer energy bills.

New Shoreham, Rhode Island

New Shoreham — Block Island — is Rhode Island’s island town, its homes exposed to full sun, salt, and relentless wind out in the Atlantic. That intense summer sun makes attic heat a real comfort-and-cost issue here, and the island’s weather asks a lot of any roof. A new Landmark Premium roof built over balanced ventilation suits a Block Island home, protecting it from the elements while keeping the summer heat load down.
