Most residential roofs in Alaska are designed for 20–40 lbs per square foot of snow load depending on local codes. Wet snow weighs significantly more than dry snow. If you notice ceiling cracks, sticking doors, or visible ridge deflection after heavy snowfall in Whitestone, call us immediately — these are signs of structural stress.

Balanced ventilation provides equal intake (typically at soffits) and exhaust (at ridge or high on the roof) so air flows through the attic rather than stagnating. Unbalanced systems with more exhaust than intake draw conditioned air from the living space rather than outside air.

Soffit vents are intake openings in the soffit (underside of the eave overhang) that allow outside air to enter the attic. They form the intake portion of the ventilation system and must remain unobstructed for the system to function correctly.

A ridge vent is a continuous exhaust vent running along the peak of the roof, allowing hot and humid attic air to escape at the highest point. Combined with soffit intake, it creates a passive convective flow that ventilates the full attic volume.

Mixing ridge vents and box vents on the same roof can short-circuit the ventilation system — air enters at the ridge vent and exits at the box vent below it, bypassing the attic volume below the ridge. These two systems should not be combined on the same plane.

Ice dams form when heat escaping through the roof deck melts snow on the upper roof surface. The meltwater runs down to the cold eave overhang, where it refreezes. The resulting ice dam traps additional meltwater that backs up under shingles and infiltrates the interior.

Adequate attic insulation reduces heat loss through the deck. Balanced ventilation keeps the roof surface cold and uniform. Together, they eliminate the warm-roof/cold-eave temperature differential that drives ice dam formation.

Most building codes require 1 square foot of net free ventilation area per 150 square feet of attic floor area, split evenly between intake and exhaust. With a vapor barrier in the attic, some codes allow 1:300. Actual performance depends on product net free area ratings.

Excessive exhaust without corresponding intake draws conditioned air from the living space, reducing energy efficiency. In very high-wind environments, improperly protected exhaust vents can allow wind-driven moisture entry. Balance is the goal — not maximum exhaust.

Signs include excessive summer attic heat (above 150°F), frost on the attic deck in winter, mold growth on sheathing, prematurely aging shingles, ice dams in cold climates, and moisture staining or wet insulation without an obvious roof leak as the source.

Insulation installed without baffles at the eave can block soffit intake vents, preventing outside air from entering the attic. Rafter baffles maintain an air channel from soffit to attic even when insulation fills the rafter bay, preserving ventilation function.

Rafter baffles (also called vent chutes) are cardboard, foam, or plastic channels installed between rafters at the eave to maintain an air space above the insulation. They allow intake air from soffit vents to enter the attic without being blocked by insulation.

A power vent (power attic ventilator) is a motorized fan that actively exhausts attic air. They can create negative pressure that draws conditioned air from the living space if intake is inadequate. Passive ventilation systems are generally preferred by most building science professionals.

Solar attic fans provide active ventilation without operating cost. They're most effective in high-sun climates where the solar gain drives both the need for ventilation and the power to run the fan. They have the same negative pressure risks as electric power vents if intake is insufficient.
