Installing A Flat Roof Requires BRAINPOWER

Flat and low-slope roof replacement is especially challenging. In terms of installation, it’s a totally different animal than composition shingle and metal roof installation.

As a result, it’s easily the type of roof installation that contractors mess up most often.

Why? Because water sheds slowly from flat and low-slope roofing. If your contractor doesn’t design the roof properly, water WILL build up and flow under the roof. As you can imagine, this creates all kinds of problems: mold, rot, decay… all the “fun” stuff.

As Greater Seattle’s smart roofer, we love “solving the puzzle” of flat and low-slope roofing. We specialize in impeccably designed, 100% waterproof PVC and TPO roofing that lasts.

Duro Last Pvc Roof Seattle

PVC Roofing

Polyvinyl chloride (PVC) roofing is a single-ply membrane. PVC roofing is ultra-durable and resistant to fire, chemicals, high-speed winds, and basically anything you can throw at it.

PVC roofing is low maintenance and can easily last you decades. It’s also an energy-efficient material that can reduce your energy costs and lower your carbon footprint. In other words, PVC roofing is the total package: premier performance, excellent efficiency, long lifespan, and exceptional curb appeal.

PVC Roofing Benefits:

  • Unrivaled flexibility makes it one of the best solutions for low-slope and flat roofs
  • Resists… well, everything: chemicals, fire, wind, water, mold, punctures, tears, and more
  • Critical for roofs with cooking oils, like restaurants
  • Hot-air-welded seams create a watertight bond and make PVC three times stronger than rubber roofing solutions
  • Can easily last decades with little to no maintenance
  • Reinforced scrim with polypropylene dipped fiberglass fibers, so the scrim is non wicking. No cut-edge sealant required!
  • UV resistance makes PVC highly efficient and reduces your home’s energy usage

Tpo Flat And Low Slope Roofing Greater Seattle Roofsmart

TPO Roofing

TPO stands for thermoplastic polyolefin. It’s a single-ply roofing membrane that provides high-end performance for a reasonable price. It’s a newer flat-roofing technology that was introduced in the 1990s that (unlike PVC roofing) doesn’t use plasticizers in its formulation. As a newer idea, the manufacturers are still evolving their formulations, so it’s cheaper and a little bit experimental.

TPO roofing resists heat, ultra-violet rays, fungus buildup, and weathering. While not quite as flexible as PVC, TPO is still exceptionally pliable, making it an excellent solution for low-slope and flat roofing.

TPO Roofing Benefits:

  • Outstanding durability—resists tearing, puncturing, mold, weathering, and much more
  • UV-resistant properties that exceed ENERGY STAR® requirements and help cool your home
  • Hot-air-welded seams make it three times stronger than conventional rubber roofing
  • Easily lasts decades with little to no maintenance
  • Always needs cut-edge sealant
  • Detail elements are all field-fabricated and not reinforced (this is a negative)
  • Lower cost than PVC roofing

Duradek Designer Rustic Plank Vinyl Roofing Greater Seattle

Duradek textured PVC membrane for walkable rooftop deck or patio cover

Walkable Rooftop Deck

Have a walkout roof deck or patio? Our walkable membrane roofing is a truly special solution that provides incredible performance and looks amazing.

This stuff is a special waterproof vinyl membrane that authentically replicates stylish roof deck materials such as wood planks, marble, stone, and poured concrete. It’s the perfect material if you want a roof deck with a stunning appearance that requires minimal maintenance. It’s got a “tread” surface texture so it’s more slip and wear resistant than a typical roof surface. A perfect fit to waterproof  your deck.

  • Cool-Step technology keeps your walkable roof up to 50% cooler than the average deck surface during hot days
