PVC Roofing

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 Roofing

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.

5 Advantages of Low Slope Roofing with Valentine

Warranty:

Valentine offers an industry-leading workmanship warranty to go alongside the manufacturer's material warranty. All of our warranties are transferable and thus add value to your home if you choose to sell.
Durability:

Hot-air welded seams, like those of a PVC roof, are the strongest and most reliable seams in the roofing industry. Because single-ply membrane is a durable material, it requires less maintenance, saving you money on flat roof repairs. PVC and TPO are engineered to be UV reflective and do not break down from exposure to UV light like other roofing materials.
Affordability:

When compared to the other low-slope options available for residential low-slope roofs, PVC and TPO roofing is affordable and offers great value for your dollar. The reflective nature of single-ply membrane roofing often reduces heating and cooling costs, saving you money over time.
Fire resistance:

Did you know that PVC and TPO roofing is naturally fire-resistant? Single-ply membrane roofing systems meet UL Class A fire rating. Scientific testing shows that this product produces minimal flame spread and is a great option for residential applications because it is much safer than other low-slope options. Your homeowner’s insurance will love that!
Low maintenance:

PVC and TPO do not require any roof coatings or other such flat roof repairs to maintain. An annual cleaning to remove algae and other organic debris like leaves, needles, and small branches is all that's required to keep your PVC or TPO roof looking and performing like new! Valentine Roofing offers a low slope roof maintenance package with every new PVC or TPO roof installation.

PVC Roofing FAQ

What is PVC roofing?

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.

How is PVC roofing installed?

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.

I heard PVC roofs cause condensation. Is that true?

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.

Isn’t PVC just for commercial buildings?

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!
