What should the decking allowance actually explain?
It should explain how exposed conditions are recorded, what repair is included and how additional work is approved.
Read full answer: What should the decking allowance actually explain?
Before removal, some support conditions can remain concealed. Ask the proposal to distinguish known repairs from an allowance for findings after tear-off. A vague statement that decking is extra leaves unanswered how quantities are measured, what constitutes a repair and who must approve it. Agree on the documentation process while there is time to compare proposals calmly.
At the exposed-deck stage, request location-based photographs and a description of the condition being addressed. Keep proposed correction, measurement and authorization together. The selected shingle documents and applicable project requirements determine the receiving surface; this guide does not prescribe a universal deck thickness or spacing. If the finding raises a structural question, identify the qualified review needed before it is covered by the next layer.
