This is one other reason to put your location in your profile. Different climates sometimes require different solutions and there are also differences in material availability, common practice, etc from region to region.

They don't need to worry about venting to prevent ice damming in Mississippi and they don't need to worry about hurricane shutters in Minnesota.

If you would have been around and checked your facts first, you would find out that many of the well respected regulars here have on many occasions posted our own work photos which pertain to a particular topic.

Other times, rather than rely on our photos, we provide a link to a respected source or repeat the sources contents verbatim to the best of our ability and time we have available to donate our time and knowledge for free to assist others in their concerns.

Woah, dude I think you took it the wrong way. No need to be touchy. I was just replying to a comment about conflicting advise. Sorry if you got offended, didn't mean to imply that you guys don't help or anything.

That is a good point. Makes sence. Sorry if anyone took offence, didn't mean it the way Ed seemed to have taken it. It was not a diss to anyone, just to show conflicting advise that I notice all the time. Seeyou makes a lot of sence, so my comment now seems stupid.

I'm with CU on this.

Normally, it doesn't really matter how hot or cold attics get - it is UNconditioned space. That's why you put insulation on the floor of the attic, to separate the hot/cold side of the house from the conditioned space below. Ventilation is NOT to regulate temperature in the house, but to regulate water vapor and keep snow from melting on the roof (ice dam).

Now if you have things in the attic that need to be in conditioned space, like a furnace or water pipes, you need to change where your conditioned space is. Either you enclose these items and insulate over them to the same depth, or you move your insulation layer from the attic floor to the roof deck.

I am in the planning stages of this move myself. I'm going to seal the vents and insulate between the rafter bays, as well as apply foam board and a radiant barrier over top the rafters, then reshingling that new roof deck with white shingles (which are only a shade lighter than my existing light grey shingles). I'm getting a tax credit for the insulation AND the shingles.

The original posters real problem is that his roof is covered with shingles that are any color other than white. Of COURSE that area is going to be hot!

The majority of the heat gain is radiant heat coming off the decking. By installing a radiant barrier under the decking ( and gables) it will drop to attic temperature close to the ambient temperature.

This is a fairly easy DIY project. We bought ours from Radiant Guard

One therory I came up with is this, they put aluminum over the exsiting sofits, where their were previous vents already, what if when they put in the alumimum they did not line up the alumimun vents with where the exsisting vents were, that would for sure not allow clear air flow into the attic, I need to look into that.............

Question on the radiant guard, we have a huge attic, with 8 foot high beams, with partical flooring up there for storage, how would you install this product with the flooring down?

You would staple it up to the underside of your rafters, creating a silver ceiling. Using the perforated one will prevent water vapor from collecting on one side or the other. Ideally, you would create the barrier between the vented area and the attic storage area, the vented air would all be channeled within one side of the barrier.
