UPVC FASCIA AND SOFFITS Information, help and tips on many areas of roofing including trusses, tiling, venting, insulation etc....

Hi

I am considering purchasing new UPVC fascia and soffits from B&Q they seem quite reasonable. Can anyone tell me if it is best to remove the old wood fascia and soffit boards first or do I just attach the UPVC over the old wood which is not in too bad a condition.

Regards
Ian

No answer? I am going to do this and also wondered how the soffit and facias should be fitted?
Please advise.

Take the old stuff down.

Check the sarking felt doesn't need replacing. If so do it now.

Nail your new soffits to the rafter feet.

Fix the fascias.

Reinstall guttering.

Don't forget to put ventilation in the soffits.

Cheers

Very good advice from Rosebery, 100% echoed by myself.

Hope this helps

Forget B&Q, go to a supplier of upvc products. The fascia to cover and fix to the existing is 9mm thick with a return on the bottom, with a depth to suit you. To strip off the old and replace with new UPVC you will need to use a different upvc product, which is thicker and will support itself.

If the edges of your roof felt is rotting (as they do), go to a roofing merchant and by some eaves trim, which is a moulded plastic item and comes in about 1.5m lengths and is not expensive. Slip these under the roof felt and fix.

Quite often the original wood fascia is fixed to form a small "tilt" to the bottom tile. Don't forget to repeat this if you remove the original.

Hi - would you also take down the wood on the gable-ends or just cover them with upvc?

You mean the barge boards?

Yes.

[rosebery]

"...............if its not rotten dont remove it"

Yes but if it's even slightly rotten you just have a case rot developing under the UPVC and you won't see it happening.

Additionally going over the top of the old also means (inevitably) that the guttering won't fit any more when you try and put it back!

[thedoctor]

If you go over the top its called capping which is Ok as long as you decorate or at least treat teh wood thoroughly first. Placing plastic capping on timber makes it sweat and it rots. As mentioned, you cannot see this rot and this is why when you look at capping which has been up a long while you will see very often the ends ore hanging away from teh facia or barge board. The timber has rotted and the nails (polypins) are no longer holding. Treat, or paint the timber well and you will resolve this problem before it starts. The problem is that most people want to put up plastic toi avoid decorating, not decorate the timber first ! If this is the case, do the job properly and rip it all off and replace with uPVC roofline facias and barge boards.

A very old topic we know, but one that is read by hundreds of people daily even in 2013. This is a great chance to say that while you are replacing, or capping, facia boards it is the ideal time to think about aluminium guttering which, as with plastic facia, needs no maintenance other than a wipe down. It's seamless, so no leaks and its wider than standard guttering, so no overspill either. Take a look at the link for more info
