What's concealed
Snow-load damage no one sees until tear-off, tight access, an occupied home, steep pitch, and landscaping protection all add labor.
What the scope should nail down
Repair boundaries, what the existing system can support, compatible materials, and disposal and restoration should all be spelled out in writing.
Permits and specialty trades
Some Grand Rapids projects need permits, inspection, engineering, or a specialty trade -- confirm that with your provider and the city directly.
