[heading-style-h3]A Smarter Way to Protect Multifamily Roofs: Seamless Silicone Restoration[heading-style-h3]
<<Who said a worn-out roof always needs replacement? At this property, we used a seamless silicone system to restore performance, stop leaks, and extend life without the cost of a full tear-off.>>
[heading-style-h4]Project Overview[heading-style-h4]
[heading-style-h6]The Situation[heading-style-h6]
The flat roof was showing clear signs of failure. Granules were wearing away, seams were splitting, and water was pooling after every rain. Repairs were no longer holding, but a full tear-off would have brought high costs, disruption, and unnecessary waste for a roof with a solid base.
[heading-style-h6]The Client[heading-style-h6]
This project covered the entire roof system for a large multifamily property in South Seattle:
- Main Roof Area: 20,000 sq. ft.
- Parapet Walls: 5,750 sq. ft.
The property owner needed a seamless, warrantied roofing system that would seal active vulnerabilities, stop leaks, and extend the life of the existing roof.
[heading-style-h4]Challenges[heading-style-h4]
- About 35% granule loss, standing water, and broken seams
- Failed flashings and coping seams around skylights, corners, and walls
- 87 vents + ridge and plumbing penetrations requiring individualized waterproofing
- Full tear-off would be costly and disruptive for a property of this size
[heading-style-h4]Solution[heading-style-h4]
Rather than tearing off the existing roof, we focused on sealing problem areas and reinforcing the surface.
- Preparation
- Full pressure wash, broom cleaning, and compressed air blowdown
- Cut blisters and fishmouths and secured to deck
- Inspected drains, curbs, and vertical transitions
- Repairs
- Sealed broken seams and repaired corners and penetrations
- All cracks, joints, and seams primed with bleed blocker
- Applied silicone system
- Waterproofed around 87 ventilation boxes, 3 ridge vents, and 50 plumbing vent pipes
