Ice dams form when heat escaping through your Canal Lewisville 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 Coshocton County inspection.

Air sealing prevents warm, humid air from the living space from entering the attic through penetrations — light fixtures, plumbing chases, attic hatches. Reducing this moisture load through air sealing complements ventilation by reducing the amount of moisture the ventilation system must remove.

Metal roofing on steep-slope applications follows the same ventilation requirements as other steep-slope systems — intake at the eave, exhaust at or near the ridge, balanced to meet code NFA ratios. Some standing seam profiles offer integrated ridge vent options.

Ventilation corrections during a roof replacement add $300-$1,000 depending on the scope — adding soffit vents, extending ridge vent, and adding baffles. Standalone ventilation improvement projects outside of a replacement have higher per-unit costs due to mobilization.

Yes. From the attic on a hot day, assess whether heat is extreme compared to outside, whether you can feel airflow from soffit areas, whether the insulation maintains a gap to the sheathing at eaves, and whether ridge vent or exhaust openings are present and unobstructed.

Yes. Adequate ventilation keeps relative humidity in the attic below the threshold where wood-rotting fungi can establish — typically below 80% RH. Attics with persistent moisture problems from inadequate ventilation often develop fungal decay on sheathing and framing members.

Passive ventilation uses convection and wind pressure to move air through the attic without mechanical assistance. Active ventilation adds powered fans to supplement or drive airflow. Passive systems are generally preferred for their reliability and absence of energy cost and mechanical failure modes.

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.
