How do you maintain polycarbonate roofing?

Cleaning polycarbonate is very simple. All you need is warm or room temperature water, mild soap, and a sponge or soft cloth. You start with cleaning the roof with plain water. Then, you mix the soap and water to make a soapy solution, and wash the roof with it.

What thickness polycarbonate should I use for roof?

If you’re using polycarbonate, we recommend a minimum thickness of 3mm for applications such as replacing shed windows to provide adequate security. If you’re replacing or installing greenhouse panes, you may want to opt for 4mm instead.
