Outgassing of SBS Modified Roofing Materials
I have an older home with a flat roof that needs to be replaced. I have severe multiple chemical sensitivities and I’m very concerned about outgassing of the materials into my attic space and ultimately migrating into the living space.
One contractor is sensitive to this issue and wants to use theTamko SBS Modified Roofing System, with the self adhesive application. I was given a sample of the base and cap sheets, and reacted very badly to them. I have looked at the application instructions, and noticed that it is recommended that ASTM D 41 wood primer should be applied to the decking prior to installation of the base and cap sheets.
Does anyone have experience with these products; how much and how strongly they outgas; and does anyone have experience with these, or similar products, in a home with a chemically sensitive person.
The contractor felt that if the system was applied on a very cool day, that everything should cure in a matter of days and be fine. Being chemically sensitive, I know that such an assessment can be very naive, as it can take weeks, months or even years for many products not to offend.
Any information is greatly appreciated.
