How to fit fascia boards

Professional fitters develop their own techniques for whatever jobs they specialise in, but it is important to follow a few standard safety procedures when carrying out any job.

With fitting fascia boards, one of the most important things to consider is that the property has been inspected for asbestos, as this material was often used in fascia boards and soffits.

If you’re in any doubt, you should contact your local authority for guidance.

Second, this type of work is not easily or safely carried out from a ladder and it is recommended that scaffolds are erected and used.

Not only will it ensure things are safe, but it makes the job a lot easier!

 

Getting started – How to fit fascia boards

Push back the second row of tiles, then lift and stack the first row to allow access to the fascia boards.

Once this has been done, check the condition of the felt along the top of the fascia. If it has dropped back, it could allow moisture to get to the exposed timberwork and this should be addressed.

The next step is to remove the guttering.

When it comes to refitting the guttering, it makes sense at this point to replace it with new; replacing old guttering can often lead to leaks and other problems.

Once the guttering is out of the way put back undamaged felt. Towards the end of the job, a section of damp course material or rigid PVC eaves tray will need to be fitted under the cut edge to allow moisture to run over the fascia and into the gutter.

The fascia boards can now be removed, but be aware that this is a heavy board with many nails sticking out. It needs to be done safely and isn’t a one-person job.

Fitting the hangars and soffit board

Sometimes the timber legs attached to the rafters will need to be knocked out so the soffit wall plate can be loosened.

Whilst this is off, check the rafters for damage and rot and then replace anything as needed. Failing to do this at this stage is a false economy.

There are several different techniques for providing a solid and well aligned set of fixing points for both the fascia and the soffit board.

For example, thick pieces of PVC can be attached to the rafter boards at either end of the run to act as hangars, but some installers use seasoned or treated timber instead.

Whatever material is used, it is important to set up a string line to check that all hangars in the run are in line, otherwise the soffit board won’t fit straight.

Each hangar should be set 10mm above the height of the last brick course, so the soffit board can be positioned between the bricks and the hangars.

Once each rafter has a hangar fitted to it, the soffit board is ready to be attached. Ensure a good fixing with plenty of nails or screws to prevent rattling during winds and always allow an 8-10mm expansion gap between boards.

Finish with soffit joint trim to cover the gaps. Once the soffit is firmly secured to the hangars, the fascia board can be attached.

Attaching the fascia boards to the soffit

Whilst the protective cover is still on the fascia boards, mark two parallel lines where the plastic nails will be attached to each rafter foot.

This ensures that when the fascia is fitted, the nails will be as uniform as possible to give the best overall appearance. Remove the protective cover and nail into place.

Finishing up

With the fascia boards now attached to the soffit, the guttering can be refitted.

Ensure the position of the running outlet above the downpipe is correct and attach the end bracket to the fascia boards at the point slightly higher than the outlet. To aid with lining these two pieces up you can post a plumb line through the outlet and get it perfectly lined up with the middle of the drain.

Next, mark out the intermediate gutter bracket positions at no more than 1m intervals, then attach and fit guttering.

Finally, fit the over-fascia drainage system.

Some installers will use a rigid plastic section underneath the felt that was cut away, which will allow any moisture to drain into the gutter efficiently. With this in place, refit the tiles and admire your work!
