Ask Foreman

Can you verify this before I keep going? I’m looking at: Running the seam in the wrong direction, trapping water or allowing leakage. What’s the approved correction for this job?

Do not

Do not hide, force, cover, or “make it work” if this affects safety, access, airflow, rated assemblies, supports, equipment, or inspection. Stop and verify the approved correction.
