If it does ever warp or twist, you will unfortunately likely have to replace the entire thing. If you Roll up Garage Door is made of separate panels in metal frames, you will be able to replace the panels that have been affected without having to replace it. It is a good idea to, when you first purchase it or have it made, to get a few extra panels so that when replacement time comes, you won’t have to search around for the same material. One thing to look out for as far as panels showing wear and age is its foundation. You’ll want to check the rails and the frame, the sliders and all parts attached to the wood. The bowing of any wooden material may affect the things surrounding it and this can be dangerous.
