Fascia capping boards

joebob

Thinking of putting upvc capping boards over existing  wooden fascia boards. What size/ length fixing nails would you use ?  and distance between nails .

I'd use 40-50mm and nailed to the rafters through the existing board.

Do you realise that the capping board will move the gutter about 10mm away from the tiles? Is the existing overhanging big enough?

How exactly do you find the rafters if they are covered up with wooden fascia boards already?

Can you not see the existing fixings?

I'll look from below - the OP said nothing about the soffits.

Failing that, I'll just find the existing nail heads.

That said, personally I hardly ever use nails and prefer screws even if they look less nice. In this case - stainless, about 25 mm, and no need to locate the rafters.

you should not put the fascia boards over existing wooden ones.It causes all sorts of problems,it makes the old wood moist and rot even quicker.All old wood should be first removed before putting up new pvc fascia boards.Its counter productive,bad workmanship  etc

It does no harm whatsoever. There's lots of wood in buildings that is covered by other materials and it doesn't get moist or rot.

No point in me arguing about it but look at all this info.the majority recommend removing the existing wood fascias

 should you put new pvc fascia on existing wooden - Google Search

An overcap depends on the condition of the fascia, soffit etc. If it's rotten it needs to come off. If it's in good condition and the HO just wants something that doesn't needs painting it's OK.

Yes there will be just enough clearance.  Do you need to pilot drill them or just hammer them straight through.stuart45 said:

All wood is in good condition, it's my mothers bungalow and she wants it doing after having new one's on the back 3 years ago.
She was quoted £600  can get it for £90 from suppliers.

The latter. The plastic is not solid, it's pretty soft and elastic enough.
