I've recently bought a new house (mid-terraced, Victorian). I wanted to put some decorative ridge tiles on the roof which I am replacing. However you have to order these online as many don't stock the these.
When ordering there are different options:
1) GRC 450mm Universal [Suitable for pitches of 18 degrees - 37 degrees]
2) GRC 450mm - 75 degree, 90 degree, 105 degree and 115 degree.
There's a lead time to order these so I want to avoid getting it wrong.
I was wondering if the universal would be suitable (although I'm not sure what angle this would be) or whether I should try and get the specific angle? A picture of the roof type is attached below.
Thank you in advance
