FAQ

Our end unit 1940"s row house has an old leaking bitumen roof . The water entry point can not be found so a replacement seems the way to go. A roofer suggested a replacement using Firestone 180, 1/2 inch fiberboard insulation covered with fiberglass base sheet, bitumen for flashing and fibered aluminum coating on wall coping . It's all Greek to be but fiberboard insulation and flashing material ? Should I be concerned?

We use kingspan insulation, marine grade plyboard , 3/4 inch, and yes you can use bitumen as flashing. I hope i am not being condescending, but the flashing is the bit that goes from the roof and a little way up the wall and is then "pointed" into the bricks, thus forming a water-proof barrier.

Would it be worth forwarding the offer to the client? Is the difference that substantial?

You don't want that. If he offers 3.5 instead of the required 3, that is a different story. Otherwise he should give you more material thickness to provide an equivalent R of 3. Yes, the difference can be substantial and I wouldn't forward it to the client. The smaller the R value of the entire roof sandwich the larger the difference it makes. Like the change from 5 mpg to 4 mpg is a 25% worsening in fuel economy, but a change from 100 mpg to 99 mpg is 1%. It will mess up the heating/cooling of the building and the mechanical systems might be inadequate. They could save money on the roof and complain how the building is too hot/too cold or the mechanical systems never shut off and their energy bills are too high.

I am building a porch roof over an existing patio. The rafters are fabricated I-beams. I plan on putting aluminum soffit under the I-beams. On top of the roof I would like to put down a metal roof. I already put down 3/4" OSB and a rain/ice barrier. Do I need insulation and/or ventilation on top of the rain and ice barrier, or can I get away without it?

the ribs in the metal roof will ventilate it - insulation is only necessary if you plan to heat it

I live in central florida. I plan on installing R-30 insulation to the floor of my attic. How effective is it to install reflective insulation to the attic on the roof side? Is it worth the price?

No dont add to the roof. The under side of the roof needs air flow and you will trap moisture, causing mold and rot. Make sure you have plenty of vents under your eaves and take your extra money and buy a solar powered attic fan (or 2 ) Mark

Sorry, I asked this in the maintenance and repair section, but no luck.Which is better to have in a 2-story home? My last 2-story home was always hotter upstairs than down. (Physics...heat rises)

the best is more attic isolation so that the heat don't come directly to second floor.

In a house, it looks like an addition, that now is the kitchen , it feels HOT, it doesn't seem to have a very good insulation on the roof at all, the ceiling is already low, so, what can be done on the outside to give it more insulation?, i don't care what it is i just want to give it a GOOD insulation, the roof is flat and to shingles. Any IDEAS? , thanks!

So there is no access above the ceiling, like a crawl space? If you cannot get above the ceiling to look then it will be difficult to determine, what you have or don't have up there. You may want to consult an insulation company for help. They may have ideas to blow in additional insulation. The spray foam that is on the link left by the other person is a foam sprayed on the roof decking and rafters when you have complete access to them. The person below me brings up another point, can you add any soffet vents to help with air flow?

I am thinking about getting cavity wall and roof insulation at the moment.But since summer is approaching, I fear that getting the insulation will mean that the house will be very hot at night. (During day time the house will accumulate heat from the sun, and the heat cannot escape).I also fear that the ventilation will be bad and the air in the house will not be as fresh.Any advice please?

Insulation helps both in heating in the winter and with cooling in the summer!

a roof that is built with the insulation covering the waterproof membrain is ?

Not done properly.
