Although this posts origins come from a job I did as a waterproofing contractor in 2013, it serves as an important lesson and example of why construction monitoring of the WRB and waterproofing is critical to ensure your building is waterproofed right.
This job started as a basic repair job; a new owner had purchased this Shell Beach home after having a home inspection. There was no specialized inspections done of the roof deck and roofing, which serves as an example of why you should have an inspection done by a specialist.
I was called because the home inspector did call out a problem with a roof deck drain. The area around the drain had soft spots in the plywood. My firm contracted with the new owner to replace the damaged plywood at the drain area only, install a new drain and waterproof it back. The owner liked the price and our plan because it was less than the credit back he got from the seller for doing the work. Note to buyers-have all repairs done before closing! The seller would have had to pay for what is coming next in this story.
