[heading-style-h3]Old Torch-Down, Sagging Deck, Standing Water — A Roof Headed for Failure[heading-style-h3]

[heading-style-h4]Project Backstory[heading-style-h4]

‍

[heading-style-h6]Introduction[heading-style-h6]

When the owners of this 25-year-old property in Lake Tapps noticed pooling water, sagging areas, and ongoing leaks on their flat roof, they knew a full roof replacement was necessary. They contacted Flat Roof Pros to not only replace the failing system but also significantly improve drainage and structural integrity. Here’s how we gave their property a long-lasting, energy-efficient upgrade.

[heading-style-h6]About the Client[heading-style-h6]

The project involved a two-story residential property with a 1,700 sq. ft. total flat roof area. The existing roofing system was a black hot tar torch-down roof that had exceeded its useful life. With multiple drainage issues and structural concerns, the homeowners needed a complete overhaul using reliable, commercial-grade materials.

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

‍

The existing roof was in non-certifiable condition, aged over 25 years, with:

• Extensive sagging and structural weakness due to prolonged membrane shrinkage
• Multiple areas of pooling water
• Failing parapet wall systems and outdated drainage
• Underlying concerns about insulation and vapor protection

‍

[heading-style-h4]Solutions[heading-style-h4]

‍

• Removal of the old black hot tar roofing and damaged materials
• Replacement of sagging and aged plywood to reestablish a solid deck
• Expansion of the cricket structure to enhance water diversion
• Installation of two new scuppers to eliminate water pooling
• Installation of vapor barriers, layered PolyIso insulation, DensDeck for foot traffic durability, and complete flashing of all roof penetrations
• Application of a Duro-Last 60mil PVC Roofing System, using a mechanically attached method for a robust wind uplift resistance
• New coping fabricated and installed on upper parapet walls for added structural protection

‍

Environmental and structural conditions required precise reinforcements and real-time adjustments to ensure the integrity and longevity of the new roofing system.

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

‍

This project delivered long-term durability through a 20-year manufacturer-backed Duro-Last material warranty, paired with Flat Roof Pros’ own 20-year workmanship warranty. The redesigned crickets and additional scuppers eliminated pooling issues, while enhanced insulation layers significantly improved the roof’s energy efficiency. Structural stability was restored by correcting all sagging and weak areas with new decking and insulation. As a result, the property now features a modern, clean, and high-performing white PVC system that adds both value and longevity.
