I had a client this morning who requested an IR scan of his living area due to major ice dams. I did my IR scan and inspected the attic and advised him on how to properly correct the ice dam issue.
My question is…What the hell causes the exterior cedar siding to stain so bad during an ice dam situation?
Is this stain from the actual cedar siding seeping (tannin bleed) and running down the side of the house?
Here are some pics…
