Fascias, Soffits & Guttering Question

Is it good practice to fit plywood boarding to soffit joints & noggins?

Dear Tradesman,

I am proposing the following draft specification listed below, I thought it would be helpful to fix Ply wood boarding to the soffit joints and noggins - in order to get an even level. However I don't want to prevent air flow even if I install vented fascias and soffits. What do you think of the following job specification. We have just completed a loft conversion to a 1930's semi and had celotex insulation in the rafters...

Also any recommendations of Eurocell or Freeform? Eurocell look a good quality product. Not sure how this compares to freeform?

Also it is essential to remove first row of tiles?
I have fitted sandtoft 20/20 tiles to the roof & they have been nailed. In order to do a proper job should they be removed?

Hello Mr Monk.
It's always recommended nowadays to try and use as less timber as possible, firstly to make your roofline maintenance free but also to "do away" with any material that is prone to rotting.
There is two different work ethics when it comes to renewing Fascia & Soffits, the first, and most preferred, is to completely remove all old timber material and replace with PVC. The second is a method called "Over Cladding" where the new PVC material is placed over the old timber. The issues caused by this is, the small gap that is created between the PVC and the the timber starts to sweat in different weather conditions, this sweat can cause the timber to dampen and over time, even decay. If your new Fascia or Soffit is nailed to this decaying timber... Well, eventually it could lead to the whole job needing doing again.
In my opinion I wouldn't use any timber to Soffit joints at all.

As for the first row of tiles needing to be removed, I would highly recommend this procedure if the job is to be carried out to a quality standard... especially if the eaves felt needs to be replaced, there is no other option.

Finally, I have used Eurocell materials plenty of times and I'm yet to have any problems at all. I hope this helps.

I'm sure it's just a "typo" but I wouldn't use white polytops on a black Fascia board.. They need to match the colour! :o)
