[heading-style-h3]Residential Roof Rescue: Keeping This Home Safe, Dry, and Worry-Free[heading-style-h3]

<<Like many older Pacific Northwest homes, this one had a roof slowly breaking down: leaks, soft spots, and a failing chimney crown. And once the system was opened up, it became clear that only a full replacement would protect the home for the long term.>>

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

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

This home in Burien had a 20+ year-old SBS/APP torch-down roof that could no longer provide reliable protection. The system showed clear signs of major deterioration: open seams, granule loss, active leaks, soft substrate areas, and a chimney crown that had begun to fail. The roof was officially non-certifiable, meaning repairs would only delay the unavoidable.

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

This 3,142 sq. ft. home needed a long-term solution after years of leaks, soft spots, and a failing chimney crown had begun to threaten interior safety. The homeowner wanted a contractor who could identify the full extent of the damage, stop active leaks quickly, and replace the system that would protect the home and prevent future moisture issues.

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

The existing system revealed several issues:

  • Active leaks and open seams
  • Soft substrate areas indicating moisture intrusion
  • Delaminating membrane across torch-down sections
  • 30% granule loss exposing the base layers
  • Failing chimney crown and aging sealants
  • Potential substrate damage under the membrane

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