Describe the existing arrangement.
Ask the person reviewing the roof to identify the ventilation that is actually present. Note visible intake and exhaust locations, accessible attic conditions and any recent insulation or equipment work. A product list without a description of the current arrangement leaves the starting point unclear.
Share the symptom in ordinary language: where you noticed it, when it happens and whether it changed after other work. Avoid deciding in advance that one vent type is the answer. The review should connect observations to a proposed change.
Ask how air is intended to move.
Owens Corning’s ventilation guidance describes intake and exhaust as parts of a working arrangement. That is a useful starting concept, but your proposal still needs to explain the selected approach for the building rather than simply adding a vent at an available opening.
Ask what assumptions were used about attic space, roof layout and existing openings. If an area is inaccessible or its condition is uncertain, have that limit recorded. Unanswered questions should remain visible instead of becoming silent assumptions in the estimate.
Keep insulation and mechanical questions connected.
A roofing change may overlap with attic insulation, ductwork or equipment concerns. Ask which parts of the review are included and which require another provider. A roofer should not be assumed responsible for every indoor comfort issue because the conversation began at the roof.
If another trade is involved, assign the sequence of work. For example, describe who handles an obstruction or an equipment opening and when the roofing detail is completed. This keeps separate tasks from being left to whichever person visits last.
Read the vent and roof details together.
A new vent introduces a roof detail that must fit the selected assembly. Ask how its location, attachment and weathering details are specified. During replacement, include proposed ventilation work in the same written scope as the covering and associated roof components.
Do not treat a product substitution as a simple color change. Ask whether the replacement product meets the same design assumptions and installation requirements. Keep model information with the project records so future service is based on what was installed.
Agree on what improvement is being sought.
Before approving work, ask what condition it is intended to address and what observations will be useful afterward. Avoid a blanket promise that a new roof vent will solve every heat or moisture concern. A defined goal makes follow-up more meaningful.
For a Lawndale roofing or ventilation inquiry, call Crown Ridge at (310) 923-7839. Describe the concern and any recent roof, attic or equipment work. That history helps frame the review before a particular product is chosen.

Questions before the next step
Should I add vents because an upstairs room feels hot?
That symptom alone does not identify the cause. Ask for a review of the relevant roof and attic conditions and clarify whether other building systems need attention before choosing a roofing change.
Will this guide calculate the vent area I need?
No. Ventilation design depends on the building and applicable requirements. Ask the qualified project team to explain the calculation and product choices for your property.
