Why Your Attic Needs to Breathe?

Attic ventilation prevents moisture buildup that can lead to mold growth and wood rot. During summer months, a properly ventilated attic can be up to 30 degrees cooler than one without ventilation.


Your energy bills benefit from good ventilation too. When hot air gets trapped in your attic, it forces your air conditioning to work harder.

In winter, ventilation helps prevent ice dams by keeping your roof deck at a consistent temperature. This protects both your shingles and underlying structure from water damage.


A complete ventilation system requires both intake and exhaust vents. Soffit vents installed under your roof's eaves provide essential air intake.

Ridge vents running along your roof's peak work with soffit vents to create optimal airflow. This natural ventilation system uses convection to move air effectively.


We install smart vents and box vents as supplementary components when needed for maximum efficiency. These components work together to maintain consistent airflow throughout your attic space.

Finding the Right Ridge Vent

Shingle-over ridge vents blend seamlessly with your existing roof design and offer excellent ventilation performance. The Air Vent ShingleVent II stands out as a premium choice, featuring external baffles that create enhanced airflow through low-pressure zones. Static ridge vents remain the most popular choice for residential applications. These vents work without moving parts or electricity, relying on natural air movement to maintain proper attic ventilation.


We also install aluminum continuous ridge vents, which provide a clean appearance and superior durability. These vents span the entire ridge length, ensuring consistent ventilation across your roof's peak. Your ridge vent's material should match your climate needs and roof design. We recommend weather-resistant aluminum or high-grade plastic polymers for long-term durability.



The vent's profile matters for both performance and aesthetics. Low-profile vents maintain a sleek roofline while still providing necessary ventilation. High-profile options offer increased airflow capacity for larger attic spaces.

External baffles on premium ridge vents help prevent water and snow infiltration. We suggest selecting vents with built-in weather filters to keep out insects and debris.

Our Roof Ridge Vent Installation Process

We specialize in creating durable attic ventilation systems that protect your home from moisture damage and excessive heat buildup.

  • 1. Installation Safety and Best Practices

    Working at height demands strict adherence to safety protocols. We require all team members to wear non-slip boots and OSHA-approved fall protection equipment, including safety harnesses anchored to secure mounting points.


    Weather conditions play a crucial role in installation timing. We schedule work during dry conditions with temperatures above 40°F to ensure proper sealing of materials.


    Our teams maintain clean work areas by removing loose debris and establishing clear paths for material transport. We place safety warning signs and barrier tape around work zones to protect both workers and property.

  • 2. Tools and Materials Required

    Basic roofing tools include roofing nail guns, utility knives, chalk lines, and tape measures. We use specialized ridge vent cutting saws for precise opening creation.


    Our material list encompasses ridge vent sections, roofing nails, underlayment, and high-quality sealant compatible with your existing roof materials.


    We bring extra shingles matching your roof to ensure seamless integration of the new vent system. Our trucks carry backup tools and generators to prevent work delays.

  • 3. Measuring and Cutting the Roof Ridge

    We begin by carefully measuring your roof's ridge line to determine the exact length needed for proper ventilation coverage. The measurements must account for any intersecting rooflines or architectural features.


    Our experienced team removes the existing ridge cap shingles and marks precise cutting lines 2 inches from each side of the ridge peak. Using specialized equipment, we cut through the sheathing to create a continuous vent slot.


    The slot width is carefully calibrated to match manufacturer specifications, typically 1.5 to 2 inches on each side. We keep the cuts straight and clean to ensure optimal airflow.

  • 4. Securing the Ridge Vent

    We lay down a specialized moisture barrier along the cut edges to prevent water infiltration. The ridge vent material is then positioned carefully over the opening, ensuring it sits flush against the roof surface.


    Our installers secure the vent using roofing nails at manufacturer-specified intervals. The nails must penetrate the sheathing by at least 3/4 inch for proper hold.


    We install end caps at terminal points to prevent water and pest intrusion. The caps are sealed thoroughly and checked for proper fit.

  • 5. Professional Inspection and Quality Assurance

    We conduct thorough post-installation inspections to verify proper ridge vent functionality. Our certified team examines the seals, flashing, and shingle overlaps to ensure complete weather protection.


    We test airflow patterns throughout your attic space to confirm proper ventilation distribution. The inspection includes checking for secure fastening and correct alignment along the entire ridge.


    We document all inspection findings and provide you with a detailed report of the installation. This report serves as a baseline for future maintenance and warranty purposes.

  • 6. Maintenance and Cleaning Recommendations

    Clean your ridge vents twice yearly to prevent debris accumulation. Remove leaves, twigs, and other materials that might obstruct proper airflow.


    We recommend scheduling professional cleanings in spring and fall. These service visits include checking the vent's structural integrity and clearing any hidden obstructions.


    Keep your attic insulation at least three inches away from the ridge vent to maintain proper airflow. Regular maintenance extends the life of your ridge vent system and preserves its effectiveness.
