Leak in roof. Visible on inside sheathing/trusses at ground level in garage. Traced back to upper (2 ea penetration points) collector mounting area. Wood was used in attaching mounting clips to roof. Wood is cracked in half – possibly allowing water penetration. Homeowner has construction experience and sealed mounting areas with pitch. Added pitch around wood mounting blocks. Suggested that he add pitch over entire wood mounting block.
Exterior insulation is deteriorating. House is up for sale.
