Ridge Vents & Attic Ventilation: What to Ask Your Roofer

A ridge vent lets air leave near the roof’s peak in a suitable vented attic system. Its performance depends on intake openings, clear airflow paths, and the rest of the attic design.

Assess intake and exhaust together

Ask how air enters and leaves the attic, whether paths are obstructed, and which ventilation approach suits the roof and attic construction. Insulation placement, roof geometry, and existing openings affect that plan.

Ventilation is part of a larger moisture assessment

Attic moisture can involve air leakage from the home, roof leaks, or other sources. The Department of Energy's durable attic guide discusses ventilation, moisture, and insulation. A roof assessment should identify the cause rather than assume a new vent fixes every issue.

A UV Exteriors project example

On our Gurnee roof replacement, the scope included a new ridge vent in place of turtle vents, along with CertainTeed Landmark PRO shingles and supporting roof-system components. That is one project solution; your roof needs its own assessment.

Turn the recommendation into a clear scope

If a ridge vent is proposed, ask the roofer to explain the intake plan and show which existing openings will remain or be changed. “Add ridge vent” on its own leaves important parts of the work unspecified.

Questions for the walkthrough

• Which roof sections are included in the ventilation work?
• What existing conditions were found during the assessment?
• Which related repairs are included, and which are separate?

Keep product information and installation photos with the roof documents. If moisture concerns persist, use those records when discussing further assessment rather than assuming more ventilation is automatically the answer.

What your estimate should identify

• The existing attic arrangement and proposed ventilation approach.
• Intake and exhaust products, locations, and installation requirements.
• How existing vents or obstructions will be handled.
• Any related insulation, air-sealing, or repair work included or excluded.
