Overview
Attic Ventilation that actually lasts here
Ventilation is the most overlooked part of a roof and the reason many fail early. In our damp climate, an attic that can't breathe traps moisture that rots the deck, grows mould, and cooks shingles from below, which is why most manufacturers void their warranty without proper ventilation. We balance intake and exhaust so your attic stays dry and your roof reaches its full life.
What you get with our attic ventilation
Balanced intake & exhaust
Soffit intake matched to ridge or roof-vent exhaust so air actually moves through the attic, not just sits.
Moisture & mould prevention
Dry air out of the attic means no condensation on the sheathing, the root cause of deck rot and attic mould here.
Protects your warranty
Most shingle warranties require adequate ventilation. We bring yours up to spec so the coverage holds.
Lower bills, no ice issues
A vented attic runs cooler in summer and avoids the warm spots that cause winter ice-damming on shaded roofs.

How do I know if my attic is badly ventilated?
Tell-tale signs are a hot attic in summer, frost or water droplets on the underside of the roof deck in winter, musty smells, mould spots on the sheathing, or shingles that aged out early. Any of those is worth an attic check.
Will fixing ventilation really extend my roof's life?
Significantly. Trapped heat and moisture are two of the biggest causes of early roof failure in our climate. Balanced ventilation keeps the deck dry and the shingles cool, often adding years and protecting the warranty.
Can you add ventilation without replacing the roof?
Often yes, soffit and roof vents can frequently be added or corrected on an existing roof. If you're re-roofing, it's the ideal time to get the ventilation right from the start.
