My brother drew up a plan for our pergola and the frame is up and its time for the roof sheeting. Heres where I need some creative thinking.
I have attached a picture to explain it better then words. (I apologise for the quality)
Ordinarily, a flashing would be put between the metal purlin and the gutter but the gap is 330mm wide and heres where the problem has come. I can only get a hold of a 300mm wide flashing and its pretty pricey.
I'm wondering if anybody has some suggestions for an alternative or some creative thinking for how I can overcome this problem?
Thanks heaps!
P.S.: I know the plan is not ideal, but at least Ive learnt for next time.
