Wood or Ployethlyne closure strips for PVC corrugated roofing?
 
Hello All:

I have a lean-to pergola at the back. I am installing PVC corrugated roofing at the top.

There will be overhangs on both sides, vertical to the closure strips. At Lowes I saw wood and polye. closure strips (http://www.lowes.com/pd_97559-1115-2214_0__?productId=3048079 and http://www.lowes.com/pd_12564-293-R79039_4294806362__?productId=3010420 )

I am inclined to use wood all throughout the project: I really do not need 100% sealing, and wood give me better support.

Any comments?

I don’t know what one is stronger. They both would need some structure below them for support so it’s just a matter of what look goes best with the rest of the design I would say.

Whichever you choose, I would stay consistent.

I am not certain that the wood give you that much more structure in this case without seeing the two materials in person.

The wood ones split and can mold up when they get wet, I've never used the plastic ones.

Thanks for all the answers.

I think I will go with the wood ones. I painted some, so it won't hopefully mold. Here in California, mold is usually not much of an issue, anyhow.

I will also pre-drill so that the wood won't split.

I'll follow up if I run across any problems.

Hello All:

Here is what I have found out so far:

- The wood ones do indeed split, even with predrilling. Fortunately, the split is localized. However, no telling if it would spread over time. The splits I have seen so far are length-wise.

The way it looks, the contour of the closure strip does not quite match that of the panels.

- The screws that they sell are a bit short (1.25"). I needed at least 2" ones in some places.

Just uploaded three photos showing the finished project:

Al, do you have the roof from the house extending over the panel roof? Is so, how much?

Actually the corrugated panel has an overhang over the roof just as it does over the patio.

See attached photo.

(If photo does not show, I will also upload it to:
