Attic moisture concerns
Condensation or staining can have more than one cause. Review the building conditions before attributing them to ventilation.
⌃ Roof ventilation & flashing
The small-looking details that belong in the big picture. Ventilation and flashing solve different problems. Ventilation design considers intake and exhaust; flashing directs water at transitions.

KNOW WHAT TO LOOK FOR
Useful observations to bring to the conversation. These signs guide questions; they do not replace a property assessment.

01 / OBSERVE
Condensation or staining can have more than one cause. Review the building conditions before attributing them to ventilation.

02 / OBSERVE
Renovations can alter intake routes, air leakage and how the attic behaves.

03 / OBSERVE
A roof project is an opportunity to discuss ventilation together with the rest of the assembly.
DEFINE THE WORK
A useful proposal explains the work and its boundaries. Confirm the actual offering, materials and availability with the team.
More exhaust alone is not a complete ventilation plan. Discuss the intended air path.
Insulation and blocked openings may affect the existing arrangement.
Air leakage, moisture sources and roof leaks can require different responses.
Any vent opening must integrate with the covering and water-management layers.
HOW TO GET STARTED
Send your ZIP, roof history and safely taken photos.
Confirm the requested work, access and assessment arrangements.
Compare the proposed materials, scope and exclusions.
Review written terms and timing before work proceeds.
YOUR PLANNING GUIDE
Keep the property history, observations and written proposal together. Use these questions to understand the next step.
Ventilation and flashing solve different problems. Ventilation design considers intake and exhaust; flashing directs water at transitions. Neither should be chosen in isolation from the roof assembly and building conditions.
Moisture symptoms can have multiple causes. Ask about attic conditions, existing ventilation paths and any limits of the inspection. Adding a vent without understanding the system may not resolve the concern.
Chimneys, walls and penetrations need clearly described work. Ask which existing components will be reused or replaced and how the proposed changes connect to adjacent materials.
Share where moisture appears and whether it is associated with weather, indoor conditions or a previous change to the building. Ventilation is only one part of an attic and roof assembly. Ask how existing intake, exhaust and other relevant conditions will be considered; adding a vent should not be presented as a guaranteed answer to every moisture symptom.
Ask which findings support the recommended work, which areas were inaccessible and what remains uncertain. Written scope should identify materials, site protection, cleanup and how changes are approved. Product terms and workmanship terms should be read separately; neither is assumed from a brand name.
Service scope and material availability require owner confirmation.

COMMON QUESTIONS
Need to discuss your own roof?
Start a conversation →No. Intake, air leakage, insulation and moisture sources also matter. The appropriate approach depends on the property.
Ask the proposal to state what ventilation work is included, retained or excluded.
No. The team reviews the request and confirms availability. An online inspection slot is pending until confirmed.
Share the ZIP, known roof history and when the issue appears. Only take photos from a safe location.
