PVC and TPO are hands down the best low-slope roof material options available. Also known as single-ply membrane roofs, they are simple to install, cost-effective, and exceptionally water resistant. Contact us for a free quote today.
Engineered to be flexible, strong, and UV reflective— PVC (Polyvinyl Chloride) roofing can easily last 20 years here in the Pacific Northwest. The flexibility of PVC roofing makes it easier for roofers to install the product around roof penetrations like vents, chimneys, and skylights found on many homes around Seattle.
TPO (Thermoplastic Polyolefin) is one of the fastest-growing roofing options on the market. Made from sheets of rubber and other synthetics, they can be easily ballasted, mechanically fastened, or chemically adhered to the insulation, creating a fire-rated, reflective, and waterproof surface. A TPO roof typically lasts between 15-20 years.

PVC Roofing Membrane is an engineered, thermoplastic, reinforced roofing system for low slope applications. PVC is heat welded at the seams creating a watertight roofing system that can withstand extreme weather, temperature, and most environmental pollutants. Because PVC is reinforced using a woven fiberglass backing, called the scrim, it is puncture-resistant, flexible and resists tearing, making it perfect for residential roofs.
PVC comes in rolls that are installed in straight lines along the roof. Valentine Roofing mechanically fastens the PVC membrane to the roof and then heat welds the seams together using hot air. This method of PVC roof installation creates a sleek appearance on any home. Once the seams have been welded, the membrane is watertight and provides excellent protection against Seattle’s weather conditions.
Condensation occurs when the air outside the home and the air inside the home converge, creating moisture build-up within the single-ply roofing system. Some studies have suggested this may be a problem specific to light-colored PVC roofing systems in colder climates such as the Pacific Northwest. Good roofing installation will prevent condensation issues. Valentine Roofing installs every PVC roof with a vapor barrier preventing air from intermingling between the climate-controlled interior of the home and the climate outside the home. When installed correctly by a trained roofing contractor with years of experience and knowledge, PVC roofing systems are a great Seattle roof.
PVC has become synonymous with commercial roofing because it is a durable material for a flat roof that requires very little maintenance. PVC is exceptionally flexible and easy to install requiring minimal labor resulting in quick installation. Because PVC is UV reflective it often helps reduce heating and cooling costs, which can be exorbitant for large commercial buildings. Consequently, all these benefits are the very same reasons that PVC roofing is the PERFECT solution for low-slope residential roofing as well!
