rafter stiffening ??
hi (wasn't sure whether to post this here or in pergola section so my apologies that it is in both although edited here for the structural only question)pergola fascia fixing - newbie
Just had a pergola built 5m long by 4.8m wide pitched roof, covered in laserlight and fixed to the fascia (on the 5m length). I had it built by some old builders who have done a lot of work for me in the past and everything else they have done is perfect but some things look a bit odd about the pergola.
my main concern is the fascia fix with lack of anything done to the house rafters.
They have just put the 140x45 rafters (pergola) straight into the timber fascia with joist hangers, and then batten screwed the fascia onto the end of the house rafters. Is this the normal way of doing it or should something be done to the house rafters for added support ??
I had a look at the house rafters and they are 120x50 hardwood (50+ year old house) with a 450mm overhang for the eaves and the majority of the pergola sits over a Lintel above a set 4m timber bifold doors which would make it difficult to strengthen the rafters back to the wall frame anyway.
This threadgot me even more concerned about rafters failing etc.... (I know this refers to metal fascia but i assume same principals)
Thanks in advance for any advice
