Carport rotting - Can I save it?

[Sonofabeesting]

Hi

I am after some advice about my car port. I believe it is about 30 years old with a slate roof. Over the years the roof has progressively deteriorated when it rains we get water coming through the concrete roof and leaving residue on my car.

I have painted the roof a few years ago but that has done little to stop the rot. Is this salvageable? Ideally I would like to replace with a double garage so it depends how expensive this fix would be.

Is this in the UK? Unusual construction. Can you post some pics of the top? You mention slate?

I live in Madrid so that would explain the different build style I would assume. I cant get a good angle but here is one if that helps

They seem to love building with concrete on the continent!

Personally if jack hammer the concrete down and skip, infill with timber and either reslate or finish with your preference. Easier and much less weight hanging about

Hard to tell, but is the slate basically decorative? looks like a very small slope, so is it a concrete beam roof with slates for appearance?

Thats a great question, and thinking about I think you are right. Its difficult to be sure but something has "gone" as there is water ingress into the concrete roof and that is causing the rebar to rust away. I am worried about large pieces of concrete coming away and dropping on the car.

Are they prefabricated slabs? Could be the RAAC stuff that is causing so much pearlclutching in UK schools, it doesn't like getting wet so will deteriorate quickly thereafter. If just ordinary precast slabs then it is still EOL, just less urgent need for remedy. The slates at that angle must be just decorative, they won't keep the water out. I'd junk it all if possible and replace with wriggly tin(probably insulated panels as single skin will be noisy when it rains, but YMMV) on the existing steel frame, which looks ok if in need of a coat of paint.

Somewhat O/T, but that's crying out for some solar panels.

Looks like it will be a pain to remove all the slate tiles and then relay.

Maybe remove the slate tiles.
Put down EPDM.
Leave EPDM as the final surface?

Thanks for the responses. I agree it looks like a right PITA to "fix" which is why I am thinking of pulling down and replacing with a double garage!
