My husband and I have recently bought a small house (1000sq. ft.) in Altadena, CA with a relatively flat tar and gravel roof. Don't know what the pitch is, but when you are standing outside looking at the house, you cannot see any roof line.

2 problems exist, that we would love to fix with a new roof, and I hope to gain insight from the expertise on this site. The first problem, is that there is no attic and no insulation in the ceiling. We have exposed wooden beams inside the house, which looks nice, but when the sun hits the roof, the heat that radiates off of the ceiling inside the house is intense. What can we do to add insulation, short of covering up the wood beam ceiling in the house?

2nd optional issue, is that we would love to have a higher pitched, spanish tiled roof, to improve the looks and curb appeal of our house.

I have not contacted any roofing companies yet. But do you guys think this is a ridiculous idea, or is it feasible? Would it cost $10,000? $25,000? More? Would the old roof have to be removed, or could a new one be built right on top of the old one?

Thank you for any input!

I think your best bet would be to remove the existing roof and have an SPF or sprayed foam roof installed. This will take care of your heat and insulation problems and also fix your roof problems.

I Think G-Tape may be onto something. I do know thatthe SPF roofs come with a good warranty from the manufacturer if you use an approved applicator, and the warrranties are renewable if you keep proper maintenance with records and a continuous UV inhibitor on it. Would give good R-per-inch value AND a good roof if properly applied.

i would sell a 3" isoboard roof with 1/2 plywood screwed in with either a single or two ply system torch-down.

but this is Master's territory

QRLF, if you are going with a 3 inch ISO, instead use 2 layers of 1 1/2 inch and stagger the boards both short and long way, you will increase your R value quite a bit. This way you will never have a seam go from the roof deck to the roofing material.

Don't tell anybody this secret, its only mine and yours!!!

wow i didnt knew that, even with a layer of 1/2 plywood on top with staggered seams with the iso, you shouldnt get any seams showing in the roofing material, ill keep it in mind..

hey G what do you use to protect yourself from this isoboard fiberglass, seems to me everytime any roofer does it comes down from the roof like if they got fleas, itching everywhere.

Q, it depends on what brand I am laying. If it is the black tarpaper brand, then I don't do anything out of the ordinary. If it is the yellow fiberglass, then I wear a long sleeve shirt and long pants until I am done fastening it. The fiberglass on the ISO never bothered me that much. Its when I have to lay the batten strip fiberglass in the accustical flutes that really does a number on me!!!!!
