Our attic gets so hot!! Is there anything we can do that we haven't already done to cool this space?
We have blow in insulation (loose) and we have a ridge vent as well as eave vents. We have one room upstairs over the garage and I feel like the attic heat is heating it up so much. Any help or suggestions will be greatly appreciated
First off, there really is nothing wrong with a hot attic as it is supposed to be hot for the most part.
The biggest issue is make sure you have:
- a free flow of air in the space (no power vents),
- any air gaps are sealed, and
- you have enough insulation PROPERLY installed. I would say R38 at minimum.
If your roof needs replacement soon you may want to consider going with a cool roof to help block some of the heat from getting in there in the first place. As for the room above the garage, I am not only wondering how the underside is insulated but how the room is (i.e. knee walls, cathedral ceiling, etc).
Really the only way anyone can help you is by seeing it. I would look for energy audit programs in your area. In some cases one provided by your local utility company may fit the ticket, while in others you might be best looking for a third party type by someone who understands older homes.
