Insulated Patio Cover Still Leaking After Repairs? Ask About TPO Roofing

Written November 10, 2026.

Quick answer: Cody Peterson, owner of City Seamless, says we figured out a way to use TPO roofing on insulated patio covers that keep leaking after repairs. Cody says it works extremely well and costs way less than redoing the whole patio cover. The first step is a free on-site design consultation: call or text 725-502-3114.

A cover that keeps leaking

Cody puts the problem simply: people have insulated patio covers, and they leak. Cody says the people who built the cover often come back out again and again ("you know, 100 times and it still leaks") because they don't know what to do.

If earlier repairs haven't stopped the leak, ask about TPO at a free on-site design consultation.

What makes a cover insulated

Our insulated patio covers use panels with a 3-inch foam core and aluminum on both sides. They keep the space underneath cooler than a standard solid aluminum roof, and the panels can hide the wiring for ceiling fans, recessed lights and outlets. We install Four Seasons Elitewood insulated systems, and our insulated patio covers page has the details.

Cody on TPO roofing for a leaking insulated cover

City Seamless does roofing as well as patio covers, and on flat and low-slope roofs our roofing side installs TPO. TPO stands for thermoplastic polyolefin. It is a bright white, highly reflective roofing membrane. Our roofing site's TPO and PVC roofing page says more about it.

Cody describes using TPO roofing on insulated patio covers as a special thing City Seamless does, and says it works extremely well. As Cody puts it, you end up with a commercial-grade roof on top of your patio cover, and Cody says you almost end up with a better product than you started with.

Choosing between a TPO roof, a re-lid and a new cover

  • A TPO roof on your insulated cover. Cody describes TPO roofing as City Seamless's option for an insulated cover that keeps leaking, and says it costs way less than redoing the whole patio cover.
  • A re-lid. New roof panels on an existing aluminum cover whose posts and beams are still sound. Our re-lid post explains it.
  • A new cover. That post also lists when a whole new cover is usually the better choice: a bent frame, sagging beams, posts that are loose or damaged at the base, or a cover you want bigger or in a different place.

At the free on-site design consultation, we can look at your cover and talk through the options.

Before you call

A few things help us at the consultation:

  • How many times the cover has been worked on for this leak, and by whom, if you know.
  • When it drips: during a storm, after one, or when the sprinklers run.
  • Photos from underneath of the stains or the drips, sent by text to 725-502-3114.
