Rated 3 out of 5 by from It is what it is! Except the description is wrong. At full price these ridge sections are expensive for what they are, I happened to buy when reduced to £9.96, so I have tried to take this into account. I am unsure who makes these and if they are of lesser quality than Coraline or Onduline. They are relatively thin but this aids flexing to any pitch of roof (they are one size fits all). The description is wrong regarding their length, they are actually 100 cm long, obviously when calculating required quantity take into consideration the overlap (I allowed 6" because I am old and work in proper measurements). I note the other brands have now incorporated ridges at each end to stop ingress of water at the overlap? I used roof and gutter sealant, running two parallel beads on each overlap to mimic the idea and also because I could, plus the smell is rather wonderful. In conclusion unless you use some other material (sheet metal, terracotta ridge tiles, old rain coats or lots of umbrella's) , which most won't, and if you have a ridge on your project, you will be buying these like it or not. So the only thing that I can actually say which is of any use, as already mentioned the length in the description is wrong. Nothing lasts forever, but no one likes doing a job twice. I have taken a chance on them as I did the job for an lovely elderly lady and hopeful I have saved her some money.
