hot attic

I have a metal roof of the teratone (brown) color over 2x4 lathing. I didn't install decking because my dad didn't think it was necessary and my neighbor didn't use any on his. Of course my concern at the time was condensation and my roof has not had this issue but now my concern is how hot the attic is getting during the summer. I do believe my a/c is having to run more than it should because of this. I have a continuous ridge vent along the entire ridge cap and 3 gable vents along with the soffit vents. What are my options for making the attic less hot? Can I put some thing along the trusses or the back of the lathing to help block the heat from transferring? HELP! Thanks,Jerry

There are various radiant barrier products that could be installed. I will say that the combination of soffit, ridge and gable vents is usually not effective. I would suggest trying blocking off the gable vents. A great source of info on venting is www.airvent.com Todd Miller

I was thinking about adding whirlly birds to the roof. Is this a good idea?

The problem is that they disrupt and redirect the eave to ridge airflow which is best for getting good air exchange throughout the attic. Todd Miller

I have a metal building with a dark green roof. It is a bad combination for centrat Texas. The dark roof transmits heat into the building like a solar collector. The building gets got like a closed up dark colored car in the parking lot. I am thinking about applying spray foam insulation such as Icenene directly to the underside of the roof. I think this would solve the problem. You may also want to consider the same for your home.
