Solar Attic Fan Installation on Existing Roofs
Many solar attic fans can be retrofitted into an existing asphalt-shingle roof. The condition of the shingles and roof deck matters because the fan requires a properly flashed roof penetration.
Many solar attic fans can be retrofitted into an existing asphalt-shingle roof. The condition of the shingles and roof deck matters because the fan requires a properly flashed roof penetration.
What Must Be Checked First
- Shingles around the installation area should be serviceable.
- The roof deck must be sound enough for the opening and fasteners.
- The unit flashing must integrate with the roofing, not simply sit on top of sealant.
- The fan location should avoid valleys and other high-water-flow roof areas where possible.
What About an Older Roof?
If shingles are brittle, badly curled or close to replacement, it may make more sense to coordinate the fan with roof replacement rather than create a new penetration immediately before reroofing.
Frequently Asked Questions
Do you inspect before recommending a fan?
Yes. Roof condition, intake ventilation and attic conditions should be reviewed first.
Can a solar fan replace ridge and soffit ventilation?
Usually it should be evaluated as part of the overall system, not assumed to replace properly designed passive intake and exhaust.
Will it lower my electric bill?
There is no universal savings guarantee. Energy use depends on the entire building envelope and HVAC system.
Can Terra Nova install the fan during other roof work?
Yes. Coordinating the work with roof repair or replacement can make flashing and placement easier to evaluate.
