How to restore fascia on a gable roof?

Hello

I would like to restore the old fascia board on my older home but sanding, priming and repainting but 1st there’s a few other issues I am unsure of before I proceed. Please forgive my lack of knowledge here aswell.

• The old wood trim has completely disintegrated from rain over the years. What would be my options to replace the trim? Could I still use a wood trim and seal it with water proof primer or can I use some metal drip edge here to stop the water leaking onto the fascia? Does Bunnings cut and deliver these materials if I give the measurements?

•I need to add some roof putty(sorry don’t know the name) between the roof tiles and fascia where it’s broken. Can a product be recommended and once dry can I paint it aswell ?

•at end of my gable roof on the left side the roof tile looks to be about 10 cam short which is leading to water damage. I have some spare roof tiles. Can I get the roof tiles cut smaller and insert a mini tile into the missing spot?

Thank you

Welcome to the Bunnings Workshop community @lukejames. It's terrific to have you join us, and many thanks for your question about repairing a roof.

You can certainly use an equivalent timber trim to replace the old one. If you go down this path, choose a treated timber moulding for durability and make sure it’s painted on all sides—including the back—before installation. Using a high-quality exterior paint, such as Dulux Weathershield, will help it withstand the weather for many years. Alternatively, a steel drip edge is also a good option, as it provides additional protection by directing water away from the fascia. Many people install both: timber for the traditional look and a drip edge over the top for added longevity. As for materials, we stock timber mouldings which can be to size for you in-store. Delivery is also available if you provide your measurements.

The “roof putty” you mentioned would be roof tile pointing compound. It’s used to seal gaps between the roof tiles and the fascia or ridge capping. Once applied and cured, it can be painted with an exterior paint to match the surrounding surfaces.

Regarding the short tile at the gable end, you can have a spare tile cut down to fill the gap, but another effective solution is to install a piece of flashing beneath the final tile, extending out over the exposed section. This ensures water is directed away from the fascia and avoids future rot issues.

Please let me know if you have any questions.

Hi @lukejames,

I have done that on a smaller scale with the gables on our two story house.

North and south gables.

Replaced the weatherboards using a cordless mitre saw mounted on a temporary frame to provide a level workspace and also the tile trim.

Repointed the edge of the tiles and decided to keep going so after painting the gables came back later with more buckets of tile pointing and did the whole roof.

This is my spot for the extension ladder and there is a rope under one of the tiles that I pull out to secure the ladder.

I also use a timber offcut and two large screwdrivers (hidden behind the tool basket) to secure the bottom of the ladder.

@MitchellMc has provided good info and you could also consider this.

Colorbond Fascia Trim.

Hi Alan

Thank you for the pictures and instructions. Looks great.
The details on securing the ladder are very helpful. I attempted to set my ladder up yesterday and it felt a little off due to the angle. I have some small plants in front of the best position for the tallest part of the roof. I did trim back the branches yesterday and will give a go the screw driver and off cut to see if it improves stability.

thanks

Update of things completed.

• small repairs to fascia

• old rotted trim removed

• primmed fascia, carport and gutters

• painted fascia, carport and gutters

• painted and installed new trim on fascia

• spot added roof pointing to spots where pointing had fallen out.

•next day added a coat of the same paint to the roof pointing

turned out allot better, by no means professional quality and it still requires a few touch up but managed to complete all steps with my wife, brother and son.

thanks all for your help.
