Flat Roofing Solutions for Spanaway Properties
Spanaway is an unincorporated community in Pierce County that has grown steadily since the post-war era, with a mix of residential and commercial properties spread across the area between Tacoma and Joint Base Lewis-McChord. Many of the older homes along Pacific Avenue and Military Road feature additions with low-slope or flat roof sections that were originally covered with built-up tar and gravel systems now well past their useful life.
The commercial corridors along Pacific Avenue South and Mountain Highway East include strip malls, retail buildings, and small warehouses with flat roofs that take the full brunt of Spanaway's annual rainfall. These aging roof systems are prone to ponding water, membrane cracking, and seam failures that lead to interior damage. Modern single-ply membranes like TPO and PVC offer dramatically better waterproofing performance and longevity compared to the older systems they replace.
PNP Exteriors provides flat roof replacement for Spanaway property owners using GAF TPO and WeatherBond PVC membrane systems. Every installation includes proper insulation, tapered drainage systems where needed, fully welded seams, and detailed flashing at all penetrations and edges. Our flat roof systems are backed by a 10-year workmanship warranty and manufacturer material warranties up to 25 years.

Flat Roofing Challenges Specific to Spanaway
Spanaway sits in the southern Pierce County lowlands where annual rainfall regularly exceeds 40 inches. Flat and low-slope roofs in this area face constant moisture exposure, and any deficiency in the membrane or drainage system will eventually lead to leaks and interior damage.
Ponding Water and Drainage Issues
Many older flat roofs in Spanaway were installed without proper tapered insulation or adequate drain positioning, leading to standing water that accelerates membrane deterioration. Our replacement systems include tapered ISO insulation boards that create positive drainage slopes, ensuring water moves to drains and scuppers rather than pooling on the membrane surface.
Military Housing and Older Construction
Spanaway's proximity to Joint Base Lewis-McChord means a significant number of rental properties and older homes built in the 1950s through 1970s with flat-roofed additions and carports. These structures often have aging built-up roofing that has exceeded its lifespan. TPO and PVC membranes provide a modern, long-lasting replacement that eliminates the tar smell and maintenance headaches of old built-up systems.
Commercial Properties Along Pacific Avenue
The Pacific Avenue commercial corridor running through Spanaway is lined with retail buildings, restaurants, and offices with flat roofs. These structures need roofing systems that can handle foot traffic from HVAC technicians, resist chemical exposure from restaurant exhaust, and provide reliable waterproofing. PVC membranes are particularly well-suited for Spanaway commercial applications due to their chemical resistance and durability.
