Commercial Waterproofing
Water does not always enter directly above the stain. Explore waterproofing and flashing repairs where the roof, walls and rooftop details meet, with an assessment of the whole water-entry problem.

Identify where water is getting in
Leaks near parapets, roof edges or equipment can involve several adjoining components. Ask for an assessment of roof and building-envelope transitions before deciding that a surface treatment alone will solve the problem.
Connect the details
Discuss flashing, copings, sealant joints, penetrations and drainage paths. Ask which trade is responsible for each detail and how the proposed work connects to the existing roof system. This planning topic focuses on roof-related water management.
Agree on preparation and verification
Ask the provider to explain substrate condition, material compatibility, preparation, access and any testing proposed before and after work. Keep documentation of the findings and completed details for future maintenance.
For water entering through the roof field or seams, start with commercial roof leak repair.
