In desert climates like Summerlin South's, concrete tile, clay tile, and metal roofing outperform standard asphalt shingles on longevity. These materials resist UV degradation and extreme temperature swings. For flat or low-slope roofs, TPO and modified bitumen membranes perform well in Nevada. Call us for a material recommendation specific to your Clark County home.

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.

An unvented (hot roof) assembly uses closed-cell spray foam applied directly to the roof deck, bringing the attic into the conditioned envelope. It eliminates traditional ventilation and ice dam risk but requires HVAC design adjustment and is not appropriate for all situations.

Yes. Inadequate exhaust ventilation allows warm, humid air to remain in the attic where it contacts cold sheathing surfaces in winter, condensing and creating conditions for mold growth. The mold is often found on the north side of the sheathing where temperatures are coldest.

From the attic, check whether you can see daylight through the soffit areas and whether there's open air space between the insulation and the roof deck at the eaves. If insulation is packed to the sheathing with no gap, the intake path is blocked.

Net free area is the actual open area through which air can flow in a ventilation product, measured in square inches. It's always less than the physical opening size due to louver and screen obstructions. NFA is the correct figure to use when calculating ventilation requirements.

Yes significantly. Poorly ventilated attics can reach 150-160°F in summer, creating heat load that degrades shingles from below, dramatically increases HVAC cooling load, and shortens shingle service life. Effective ventilation keeps attic temperatures much closer to ambient outdoor temperature.

Ventilation corrections during replacement typically involve adding or enlarging soffit vents for intake, installing or extending continuous ridge vent for exhaust, and adding rafter baffles at the eaves to maintain the intake air channel. These are efficiently done at replacement time.

Cathedral ceiling roofs have no accessible attic and must maintain a ventilation channel within the rafter bays themselves. This requires specific rafter depth, baffled ventilation channel, and ridge-to-soffit airflow path. Getting this right during construction or replacement requires careful planning.

Yes. Ridge vents can be cut into an existing ridge, additional soffit vents can be installed, and box vents can be added in specific attic zones. However, the most cost-effective time to correct ventilation is during a roof replacement.

Yes, primarily in cooling-dominated climates. Properly ventilated attics maintain lower temperatures that reduce heat transfer into conditioned living space, decreasing HVAC runtime. The energy savings are most significant in homes with inadequate insulation and high summer temperatures.

A gable vent is a louvered opening in the triangular gable wall at each end of a gable roof. They work well in cross-ventilating applications but are less effective than soffit-to-ridge systems at ventilating the full attic volume. They should not be combined with a ridge vent system.

Yes. Birds nesting in soffit or gable vents and wasp or bee nests in ridge vents are common blockage sources. Inspecting vent openings annually and installing appropriate screening (without reducing net free area below requirements) prevents this.
