Premium Single-Ply

PVC Roofing

Polyvinyl Chloride (PVC) is the gold standard for durability. It is highly resistant to chemicals, fire, and wind, with heat-welded seams that stay flexible for decades.

Flat Roofing FAQ

Expert answers for Kirkland homeowners and property managers.

How long does a flat roof last in Washington?

In the Kirkland area, a professionally installed PVC roof typically lasts 25–30+ years due to its high resistance to environmental factors. A high-quality Torch-Down system generally lasts between 15–25 years.

Is PVC better than TPO?

PVC is often considered a premium upgrade. While both are heat-welded, PVC offers better resistance to grease, oils, and chemicals, and it typically maintains its flexibility longer than TPO in extreme weather cycles.

Can I walk on my flat roof?

Yes, both PVC and Torch-Down are designed to handle occasional foot traffic for maintenance. However, they are not intended to be used as decks or patios without a secondary protection system (like pedestal pavers).

Does PVC stay clean in the PNW?

PVC is naturally resistant to mold and algae growth, which is common in Kirkland. While it will accumulate some dust over the years, it is very easy to clean and maintains its white reflectivity better than many other systems.

Can you repair a flat roof instead of replacing it?

If the leaks are isolated and the underlying insulation is dry, we can often perform a patch repair. However, if the membrane is severely aged or if the insulation is saturated, a replacement is necessary to prevent structural rot.
