Insulation Sprayed On Underside Of Roof Deck

[Mr Rex]

You are preaching to the choir. I am a Home Inspector, formerly GC( if the market returns so will I), and spent over 6 years inspecting large commericial projects for an Architectural firm. I also was involved in some inspections/investigations relating to a lawsuit over some spray foam roofing material that several "Design Professionals" signed off on. Some of the worst POS ever.

Mr. Rex:

That's good to know, you might be interested in what we are doing in the Bay Area, here are two projects of a former employee of mine, a Palo Alto addition, and a new home in Woodside, Steve Jobs is trying for a new home approval again, en economical $13.75 million dollar home, but another environmental group has sued again to block him. That's peanuts, Larry Ellison's Japanese style home ran $70 million, a former empoyee of mine was the superintendant on another $68 million home, it had $6 million worth of cabinets in it. Here is a Saratoga home I have in design and am coming out of retirement to build. Interesting that the first home I built was $6 a square foot, when I got $10 a foot in 1968 I thought I had hit the holy grail, now it looks like the last one will be far above $1,000 a square foot. And as you are aware square footage has little to do with construction costs.

BTW, Ellison appealed his assessment on the basis of functional obsolescence and got a million dollar a year reduction in his taxes.

RE, sheathing. Thanks to a Texas hail storm, got my roof stripped to the rafters, and new sheathing with radiant barrier attached to it installed. Cut my electric bill by 40%. Saw the change the first month.

You can seal the home, making the home a giant cooler, and do other things. But the cheapest thing you can do if you have to do a full roof strip is to install the radiant barrier with the sheathing. My new roof will pay for itself in reduced electric bills in about 6 years.

Insulation

What is your concern? the subject was built in 2007, you are not a building inspector. I would prepare the appraisal to meet MPS and not worry to much about the insulation. Typically todays foam insulation is better weather its closed cell or open cell.
