Not all house siding or roofing materials contain asbestos. If you are concerned the material might contain asbestos, you can ask your neighbor whether or not the material has been tested for asbestos. Federal regulations regarding renovations or demolitions of asbestos-containing materials do not apply to a homeowner’s renovation of their home. State or local regulations may be applicable if the siding or roofing materials do contain asbestos. Contact your state regulatory agency or local government building department about such requirements.
