This Shoreline 50 mil PVC roof project features a 50 mil gray IB PVC membrane by IB Roof Systems installed on a low-slope roof in Shoreline, Washington. Pinnacle Roofing Professionals also added a custom vented ridge system and rebuilt the chimney from the roofline up, combining flat roofing and masonry work under a single warranty.
Project Overview: Shoreline PVC Flat Roof Replacement
Located in Shoreline, WA, this project called for a durable, long-lasting flat roof solution. The Pinnacle Roofing crew installed a 50 mil IB PVC membrane with heat-welded seams for reliable waterproofing. To improve attic ventilation and airflow, we added a custom vented ridge system. The chimney, which had deteriorated above the roofline, was rebuilt by our masonry team and properly flashed into the new PVC roofing system.
