Vermiculite removed from an attic before soft roof boards are replaced
Example project
- Home
- 1950s one-story house in Crystal with loose fill in the attic
- Original request
- Tear off the old shingles and replace the roof boards that feel soft underfoot
- Testing
- An MDH-certified inspector tests two materials: the loose attic fill and the felt under the shingles
- Found
- Asbestos in the vermiculite between the ceiling joists
- Clear
- No asbestos in the felt under the shingles
- Area
- About 1,000 sq ft of attic floor
- Timeline
- Five-day notice, then three working days
- Cost
- $9,500
In this example, a roofer looks at a 1950s house in Crystal and finds several roof boards that need to be replaced. Once those boards come off, dust and debris fall straight into the attic, and the attic floor is covered in loose, pebbly fill.
