Replacement Fascia and Soffit Boards
Step by step instructions on how to replace timber roofline boards with Upvc
To the left you can see an old roofline with rotten timber boards and peeling paint.
As you will see the old boards are to be fully removed rather then "capping" over them. Full replacement is the best option regardless of the condition of the existing timber.
The boards are fully removed
The first row of roof tiles are removed and set aside for re-use.
The existing felt is cut back a few inches and then the existing timber fascia and soffit boards are removed using a crowbar/prybar.
At this point any rot to the timber ends would be cut out and replaced with new treated timber.
The Upvc soffit boards are installed
The new Upvc soffit boards are fixed to the timber rafter ends with stainless steel plastic capped nails.
The back of the soffit board rests on the top of the wall and is pinched down with timber "legs" to prevent the wind from lifting the board free.
The soffit boards used in this installation are 10mm thick and 5 metres in length.
The fascia boards are then fixed to the roofline
The 18mm Upvc fascia boards are then fixed to the timbers with 65mm stainless steel nails.
Two nails are used to prevent any buckling of the board - considering the board must hold the weight of the roof tiles and the guttering this is a must.
Extra care is taken not to obstruct any window openers!
Eaves ventilation and guttering
A 10mm eaves vent strip is then fitted to the top edge of the fascia board - to prevent loft condensation.
The gutter support clips are then screwed to the fascia, a string line is used to ensure the gutter has the correct gradient fall and all water flows freely to the
pipe outlet.
Upvc plastic guttering
The Upvc guttering is then "clipped" onto place and all joints are screwed to the fascia to prevent any movement.
The gutter is then tested with water to ensure everything ios leak free and working correctly.
Eaves felt to roofline
Replacement eaves felt is then fitted - tucked under the existing roofing felt and overlapping into the guttering.
The felt is rigid and unlike traditional felt is designed not to sag behind the fascia boards.
Should a tile on the roof break any raiwater should be directed into the gutter. A bird stop comb can also be fitted to the top edge of the fascia to prevent birds from entering the loft.
The finished product!
The tiles are re-laid on the roof and all the upvc materials are cleaned and a sealant is applied to the wall and window frames.
