Fascia and Sofits : How best to "Rake" them

    To abide by our planning permission I need to have our Fascia and Sofits rake back along the roof.

    The problem is that the wall plate is blocking this from being a neat and tidy little job and would require. Them to rake back create a smal box and then continue to rake back upwards.

    This is obviously the non standard way of doing things, as you would usually create a box around the wall plate and ten rake back up with the roof.

    So I was wondering if anyone had any suggestions as to how I would get the best looking results for this. I would like to avoid having to go through planning permission again and my Engineer has really clamped down on letting these thigns slide. So I am trying to find a way to get the best results from this situation.

    Cheers

    If your talking about getting rid of the eave boxs at wallplate level on the gable end . Its easy . The way i do it is when setting out the wallplates keep the back from the out side block so its not overhanging the out side . Cut the common rafters as normal . For the last rafter at the inside of the gable and the two over hanging rafters should be taken aside on the work bench line up side by side check with a square . Then get a off cut of 6*2 and mark the nochts on the top of the rafters on the flat of the 6*2 so the nochts are 2" deep . @ 1200mm centers along the lenght of the rafter . Making sure that all cuts are a neat & tight fit . When erecting the roof have lenghts of 6*2 to hand to acts as noggins which will run from the second rafter in to the outside rafter {around 1300mm long} , leave it over hang the last rafter you will need to line the last rafter {Cut off when finished lineing} . when fixing these 6*2 best to use 6*100mm screws . By doing this method the over hand is balanced of the main roof dus not needing any support from the wallplate . :cool:

    can you describe what you mean by 'rake back along the roof'..? how can a soffit rake along a roof, as a roof is an external sloped plane?

    are you talking about a flush eaves?

    The standard practice is to create a box around the wall plate (the timber that juts out to hold the overhang rafters).

    The problem with our planning permission is that we are not allowed to create this box and we have to run it right back along the roof.

    So what happens is that as it runs back along the roof it hits the wall plate and thus does not allow for it to run flush along the roof. This is the problem that Im looking to try and resolve, the roof is complete and I wasn't able to picture how it would look until now (not a builder and no houses in the area have this style). So I am wondering if anyone has any experience or ideas on how to resolve this.

    I have asked the building if he could trim down the wallplate, but given that it supports 2 rafters he doesn't want to do it. I have looked into making Fascia / Sofits larger, so that it covers the wall plate and still runs flush along the wall (This could proportionally look stupid).

    When I get home from work I might be able to do some photoshopping to explain what I mean.

    not on a conventional build. The wall plate is usually located above the inner leaf (block or TF) and the rafters basically cantilever over it. These rafter ends are then usually boxed to create a fascia and soffit.

    sounds like what you are required to do is build a flush eaves... something like this?...

    Hi All. I'm a little late getting in on this thread but I was hoping to get some advise.
    My builder started forming the raking soffits on my roof but the result is a cold bridge has been formed at the cavity closer block. The j-rail for the soffit is fixed to the outside of the cavity closer block, unlike the standard soffit which has a box formed around the cavity closer block.
    The builder said there's no way of avoiding this with a raking soffit & said i'd have to box out &form standard facia&soffits.

    Does anyone else have any experience with this?
    Thanks
