Ice dams form when heat escaping through your West Pittsburg roof melts snow near the ridge, and that water refreezes at the cold eaves. The ice forces meltwater under shingles and into your home. Prevention requires proper attic insulation and ventilation — both of which we assess during every Lawrence County inspection.

No — this is a common but harmful mistake. Closing vents in winter traps moisture in the attic, leading to condensation, mold, and ice dam conditions. Attic ventilation should operate year-round. The warm-side air barrier and insulation are what manage comfort, not vent closure.

A hot deck refers to a roof assembly where the insulation is placed at the roof deck level rather than the attic floor — typically in an unvented or conditioned attic design. It's an intentional design choice rather than a problem, but it requires specific implementation to manage moisture correctly.

Poorly ventilated attics add significant heat load to the HVAC system in summer — duct systems running through a 150°F attic lose efficiency, and the heat transfer into the conditioned living space increases cooling demand. Improved ventilation reduces both effects, lowering operating costs.

Proper attic ventilation prevents heat and moisture buildup that degrades roofing materials from below. In summer, ventilation reduces attic temperatures that accelerate shingle aging. In winter, ventilation keeps the roof deck cold and uniform, preventing ice dam formation.

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.
