[heading-style-h3]Seattle School Roof Restored Without Class Disruptions[heading-style-h3]

[heading-style-h4]Project Overview[heading-style-h4]

‍

[heading-style-h6]The Situation[heading-style-h6]

A Seattle K–8 school was dealing with the classic signs of a failing flat roof: recurring leaks, water pooling after rain, and worn surfaces from years of sun exposure. With classes in session, a noisy tear-off wasn’t an option. They needed a quiet, safe, and reliable solution—fast.

‍

[heading-style-h6]The Client[heading-style-h6]

This public K–8 school serves hundreds of students in the heart of Seattle. Their 10,000+ sq. ft. flat roof, covered in aging acrylic over SBS/APP, had outlasted its warranty and was letting in new leaks with each storm. Previous patchwork repairs weren’t holding, and the facilities team needed a durable fix that wouldn’t disrupt learning or break the budget.

[heading-style-h4]Challenges[heading-style-h4]

‍

By the time Flat Roof Pros arrived, the roof showed multiple issues:

• Standing water around low points and clogged drains
• Dry-rotted plywood in sections of the deck
• Cracked acrylic coating over the old SBS/APP system
• Unsealed HVAC penetrations exposing the building to leaks
• No active warranty, leaving the school fully at risk

‍

‍

[heading-style-h4]Solution[heading-style-h4]

‍

Flat Roof Pros recommended the GE Enduris 3500 White Silicone Roofing System, a seamless, UV-resistant coating applied directly over the existing roof. This approach excluded the need for tear-off, avoided classroom disruption, and delivered long-term protection.

‍

Prep & Repairs

• Pressure washed and cleaned the entire surface
• Repaired blistering and weak seams
• Replaced rotted plywood
• Applied flashing around HVAC units, drains, and parapets
• Used bleed-blocker primer for strong adhesion

‍

Silicone Application

• Reinforced vulnerable areas with silicone and mesh fabric
• Applied a full topcoat for waterproof protection
• Finished with a reflective cool-roof layer to lower A/C costs

‍

[heading-style-h4]Completed Project[heading-style-h4]

‍

Work was finished quietly and safely while school remained open. The school gained:

• A fully watertight, warrantied roof
• Improved drainage performance
• Lower cooling costs from reflective coating
• Peace of mind for facility managers
• A project delivered on time and on budget
• 20-year manufacturer and workmanship warranty

‍

[heading-style-h4]Ongoing Maintenance[heading-style-h4]

‍

To protect their investment, the school joined our Maintenance Plan, ensuring regular inspections, debris removal, and touch-ups.

‍

[heading-style-h6]2023 Recap[heading-style-h6]

• Removed bird debris
• Re-sealed surface scuffs caused by natural wear

‍

[heading-style-h6]2024 Recap[heading-style-h6]

• Unclogged a slow drain
• Touched up silicone in a minor trouble area
• Roof remained fully sealed and weather-tight

‍

[heading-style-h6]5 Years Later: Still Going Strong[heading-style-h6]

Today, the roof is still:

• Leak-free and high-performing
• Fully reflective and energy-efficient
• Protected by both warranties
• Maintained proactively to prevent costly repairs
