Why New Brunswick attics need this
People hear "Atlantic Canada" and assume the only attic problem is winter. Summer is the bigger surprise. Moncton and Fredericton run 22°C to 26°C (72°F to 79°F) in July, but the attic does not care about the outside number. Under dark asphalt shingles in direct afternoon sun, even a 24°C day pushes the attic deck to 50°C (122°F) or higher. Attic probes in Moncton and Saint John homes regularly read 52°C (125°F) on plain July afternoons. That heat radiates straight down through the upstairs ceilings all evening, and most New Brunswick homes were not built for AC.
The winter story is the other half. From November through April, attics fight moisture from two directions. Indoor humidity from showers, cooking, and wood stoves rises and condenses or freezes on cold sheathing. Snowpack melts from below when attic air warms, runs to freezing eaves, and forms ice dams that push meltwater back under the shingles. Bay of Fundy humidity makes this worse on the south coast.
A solar attic fan handles both jobs. In July it moves the trapped 50°C air out. In winter it pulls moisture out before it can freeze on the deck.
What we install
One 30W solar attic fan with the panel built into the housing, mounted on the back slope where it does not show from the street. The installer cuts a clean opening, flashes it for Nor'easter wind-driven rain and snow, runs a humidistat, and ties it off. Professional install in a single visit. No electrician, no new circuit, no operating cost added to your bill.
What you'll save
The average New Brunswick home uses about 12,000 kWh per year because electric heat is common across the province. A typical summer power bill in Moncton or Fredericton sits near $120 in July. Owners who install a solar attic fan usually see an 8 to 15 percent drop in summer cooling cost (per U.S. Department of Energy residential cooling-load guidance). The bigger payoff is the winter side. Ice dam interior damage runs $4,000 to $10,000 per claim in Saint John and Moncton, and many homes get hit more than once a winter.

Installed by New Brunswick authorized installers
New Brunswick building stock leans on 1900s to 1920s wood-frame homes in Saint John's historic uptown and downtown Fredericton, postwar bungalows across Moncton and Riverview, and 1990s-on builds in Dieppe and around the Moncton ring. Saint John's Trinity Royal heritage district has rules about street-facing roof equipment, and back-slope mounting clears them. You pick a date, the installer shows up, and your attic stops baking in summer and stops freezing moisture all winter.
