Roof ventilation and attic heat in Treasure Island homes
Why ventilation quietly decides shingle life and cooling load on a Treasure Island house.
Attic temperature is the cheapest lever most Treasure Island homeowners never pull, and it quietly decides how long the shingles above it last.
What bad ventilation does
- Cooks shingles from underneath, shortening their service life
- Raises attic temperature, which raises cooling load
- Traps moisture, which finds decking and insulation
Intake and exhaust have to balance
Ridge vents with blocked soffits do nothing. The system needs low intake and high exhaust, sized to the attic area. Balance matters more than the brand of vent.
What we check
Soffit obstruction from insulation or paint, net free area against attic square footage, mixed exhaust types short-circuiting each other, and bath and dryer fans discharging into the attic — common in flat-roof mid-century beach homes on canal lots.
Ventilation and solar
An array shades the roof plane it sits on, which helps a little. It does not substitute for ventilation, and vent placement should be coordinated with array layout so nobody blocks a ridge run.
When to fix it
During a roof replacement. Retrofitting ventilation on a sound roof in Pinellas County costs more per vent and buys you less.
