An overheated attic can bake asphalt shingles on the roof and cause them to deteriorate.
Attic too hot for ac.
We live in south east texas.
My idea is to vent the build up of hot air that has risen to the ceiling in the hotspot rooms into the attic so that air from cooler parts of the house can move in.
If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage.
In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth.
Hang pencil and paper next to the thermometer and record the outdoor and attic temperatures.
And it can cause your air conditioner to work harder than it needs to and send your energy bills soaring with the temperature.
Furnace coil and ducts are in the attic in a very hot environment apparently somewhere in the furnace the air gains 4 to 5 degrees and maybe 1 or 2 degrees more in the ductwork.
Hang an outdoor thermometer in your attic making sure its range reaches at least 130 degrees fahrenheit.
As a certified licensed home inspector it is not correct to say too much ventilation is bad for an attic unless rain moisture is.
An unventilated attic can reach 150 degrees in the heat of summer 50 degrees higher than it should be.
