As long as we are asking home improvement questions...

Asbestos Shingle! Yikes! Many people are encapsulating asbestos instead of removing it like we saw in the 80's-90's. I've dealt with a lot of it in floors. They realized the removal was making everything go airborne. You've got me stumped with that one. Maybe vinyl ciding could help there? I know it would also increase your r value somewhat and might alleviate the asbestos problem at the same time. I'm just a DIY guy that loves old homes. Perhaps one of the contractors on the board could chime in.
