How do you cut plastic roofing?

Question

I want to put up some corrugated plastic sheet roofing,but cannot find any the size I need-so I am going to have to buy large and cut it down to size. Thing is I have been told it is very difficult to cut without splitting it. Anybody know any tips/tricks that will help me do this please?

very fine tooth bladed saw,u could use jig-saw but take it carefully,let the saw do the work,dont push to hard it may snag.

Answer 2

You can use snips to cut it

Answer 3

any of the above just make sure the sheet don't judder make sure its on a flat surface.

Answer 4

looks like there are a lot of ways to do it.

I've cut similar product with a masonry blade in a circular saw.

It's quick, effective, no spliting, some scorching along the cut.

Face and eye protection are a must.

Good luck.

Answer 5

I found the easiest way was to use an angle grinder with a metal cutting wheel in it . I cut ten sheets this way only a week ago, make sure you wear eye protection when you do it and the sheets are on a good flat surface.

Answer 6

Cut with a hand saw with fine blade. Make sure it is properly  and fully supported and go gently, being careful where you put your own weight on the job.

Answer 7

Jigsaw - with plastic cutting blade.

Only reason it splits is because people tend to try and cut it with a hand saw and it judders - which causes it to split.

Another way is to score it with a sharp Stanley knife on both sides and then cut with a saw.

I have never had a sheet of this stuff split or crack on me when cutting - because I use the right cutting blade.
