I am looking for a replacement roof canopy for my canopy, a 10 ft. x 20
ft. steel frame canopy, P/N 680344 from Costco. The P/N is 2004-D,
14'4"/4.3m x 22'5"/6.8m Polyethylene canopy roof. The manual has a
customer service number of 1-800-929-9517, but when I call it, I get an
ad, or service not available message. Anyone have any luck getting a
replacement roof for this popular canopy ?



We have been using the Costco canopies for several years. They are made of
a cheaper plastic in China. We no longer replace the roofs with the
original Chinese plastic, but have merely left the old roof material in
place and just placed a piece of white tarp over the existing plastic roof
material, ending up with two layers: the old plastic material on the
bottom, and the new white roof tarp material on the top.

We tie down the white tarp using the heavier nylon cord (from Home Depot),
leaving the ends of the tarp "puckered" enough at the peak of the roof to
let the air travel between the white tarp and the underlying old tan roof
material (if the white tarp material is too tight, condensation may occur).

When you use the new white tarp, the canopy is cooler beneath because the
sun is reflected better, and when the roof needs replacing (which is at
less frequent intervals), you can just remove the white tarp and replace
it by buying it locally, bypassing the pain-in-the-neck outfit in Southern
California that Costco uses. As for the sides, you still have to go
through the Chinese importer, but I don't have the phone number. I
remember that the last time I required new side panels, I called Costco in
Kirkland, Washington. Sorry that I don't have the phone number at hand.

Good luck!

P.S. You should attach the "feet" of the steel framework to a wooden
"foundation" on the ground to prevent splaying of the canopy legs. I used
pressure-treated 2x6 lumber, attached with flat steel reinforcement pieces
shaped like the letter T and letter I. These were screwed into the wood,
resulting in a fairly solid framework, with cross-pieces at the end and in
the middle. I then added some building blocks to weigh down the wooden
framework so the wind wouldn't blow it away. The canopy has never budged,
even after ten years.
