Defect description
Pic by Doug Edwards, Acorn Home Inspections Roof23a
Defect: Roof decking (sheathing) at junction point where drainage waste vent
pipe exits through roof has large, highly visible moisture damage. Discoloration
of sheathing and evidence of leaking is present on piping. Boot and or flashing
is probable cause of this condition. Recommend repair ASAP or roof sheathing
and installation of proper boot and flashing by licensed, qualified roofing contractor.
Failure to do so will lead to future major damage and very costly repairs.
Note: Since this is an inside picture, this statement can only be verified by
examination of the boot on roof so I am "guessing" here and can only go by the
water damage evidenced here.
