Skylight repair help

Hi Folks!

I have a skylight in a bathroom that is in need of some loving. In the pic

attached it shows how the moisture has gotten to the corrugated sheets.

I'm looking for some advice on what material I should use to replace it, and also any advice on a diffuser to replace the existing air grill?

Would a new polycarbonate/similar corrugate work like in the picture?

Many thanks for the help!

Hello @Deaks456

Thank you for sharing your question about repairing your skylight.

It looks like water has entered through the roof and destroyed the timber inside the light tunnel. I suggest inspecting the seal of the perspex on your roof. If it has deteriorated this will need repair. Remove the old seal with a Trojan 6 In1 Multi Paint Scraper making sure not to damage the perspex. I suggest using Selleys 310g Roof And Gutter Silicone - Translucent to seal the perspex back onto the roof. Once re-sealed you can proceed to repair the light tunnel. Please make sure to take all safety measures when working on your roof.

I recommend taking the damaged panel off carefully and try to determine what type of material it is. From the photo, it looks like very thin plywood. Once you have taken it off would it be possible for you to post a closer photo of the panel? This will give us a better idea of what to recommend to repair your skylight. If it is plywood, you will just need to cut several pieces in the same dimension and paint them with exterior paint. I suggest replacing all four panels in the tunnel and sealing them with the Selleys Roof and Gutter Silicone.

Let me tag our experienced member @TedBear for his recommendations.

Please keep us updated, we look forward to seeing your skylight repaired.

I agree with EricL's approach to 1) fixing the leak, then 2) replacing the lining.

As to replacing the air grill - if you are ok with leaving it there as a support, you could use a piece of white Corflute to reduce air flow/heat transfer, look neater and also disperse the light more evenly. It is cheap, easy to cut (knife or big scissors) and lightweight, but it doesn't have much stiffness, so it might sag without the support of the existing open grill.
