Penetration Detail Instructions
Vents, pipes, drains, skylights, and HVAC curbs are where roofs actually fail. Every penetration gets three courses: Acrylic Gel, polyester detail strip, and Gel again. Then the full system goes over the top.

Acrylic or silicone?
Choose an option to see its layers in order. Our team checks the roof, primer, coating thickness, and product amount before the project starts.
Common roof concerns
- Cracked field-applied sealant
- Open corners and fishmouths
- Movement between dissimilar materials
Field preparation
- Remove failed material back to a sound edge
- Apply Gel, polyester detail strip, then Gel again
- Tie the cured detail into the field system
Release checkpoints
- Fabric follows the geometry without bridging
- No pinholes remain
- Drainage paths stay open

Answers before the roof brief.
Use these answers for planning, then follow the current written specification for the project.
Can an existing Details roof be coated?+
A Details roof may qualify when the assembly is identified, sound, dry, repairable, properly prepared, and proven compatible through project-specific testing. Wet or unsound areas must be addressed before coating.
What preparation does Penetration Detail Instructions require?+
Preparation depends on the exact substrate and condition. Inspection, moisture review, cleaning, drying, repairs, detail work, and representative adhesion testing come before the final primer and coating sequence.
How is the material quantity calculated?+
The estimator uses measured roof area, detail length, system family, planning term, and a waste or texture allowance. Actual ordering must follow current coverage rates, specified film build, surface profile, and field verification.
Which technical documents belong in the project file?+
Start with the system specification, then include the current product data, safety data, applicable detail drawings, approvals, warranty requirements, and any written project-specific instructions.
When should the technical team review the roof?+
Request a review whenever the substrate is uncertain, moisture or drainage is a concern, adhesion results vary, prior coatings are present, warranty coverage is planned, or field conditions differ from the published system.
