Roof rot?

I wonder if it was a different colour previously?
There are soft top roof dyes available, some also recommend using their pre-dye solution to help it "take". I've used one of the dyes on mine, and it has made an appreciable difference.

It is a little odd, have it thatched & set a trend!

What colour was it? going by the pic it's a bit hard to tell

I have found that a wet vacuum cleaner and standard carpet-cleaning products work well for initially cleaning dirty hoods. I bought a dirty, secondhand hood and frame, (with a glass screen) to replace my generally better hood which had a cracked plastic screen). Perhaps needless to say, after a heavy dose of carpet-cleaning products, thorough rinsing with clean water in the wet vac, followed by a few days drying then fresh waterproof and dye will be essential.

Looking at it again, it might’ve been red, if so that will be the hardest colour to get right, most red pigments are prone to fading and also the most expensive.
it’s quite possible that attempts to restore it to the original deep red will only end up a brownish red….or worse a reddish brown!
If it is meant to be black then it might’ve  Suffered from chemical attack flue to fallout from being parked near some industrial plant.
 I recall when they closed the Goodyear plant in Thomastown, 
I had the job of packing up all the machinery ant relocating it to the Somerton plant. 
Some well meaning office Johnnie had desided that planting fruit trees all around the perimeter of the grounds was a good idea…the result was fruiT as hard as cricket balls that tasted like rubber. Even the birds and bats wouldn’t though it. The fallout from that plant Goodyear would pay all all the council rates of the neighbours and have their roofs repainted every year. 
And I remember down at Yarraville where you had the ICI chemical works, the Pivot fertiliser plant, the CSR.sugar works and the Mobil oil terminal all in a row. The fallout from that lot would strip the paint fr The workers cars before long.

Once you have cleaned and sorted it, I use one of these,

my car sits outside as an older more vulnerable model has the only garage in my possession
It works well, is easy to take on and off and folds into a small square zip up case it comes with.
On very wet days moisture will be captured on the inside of the rear screen, but my TF is my daily driver, so a quick wipe usually sorts it.
Most importantly, the wind has not yet blown it off, the elasticated straps are very good.

Its not just the UK where they don't give a toss if they can get away with it then.
I recall local studies on sulphur fall out showing high pollution figures blamed on old petrol vehicles.
When they closed the local steel plant the readings plummeted, just a coincidence apparently.
Personally I would rather the steelworks was still open, maybe fitted with a sulphur scrubber though.

Sorry, for some reason the forum doesn't alert me any more when I get a reply! Also when I quote somebody now, I have to reply in the "quote" box - don't know what's going on.

It was a black top!
 

Sorry I missed all the helpful replies - I don't get notifications any more for some reason - must have a look and see if I can figure out why...

So it might have been red at some stage in its life! Oh well. Head gasket went yesterday, so the roof has slipped down the priority list a bit for now

That roof looks like it needs a deep clean, if it was mine I would start with my jet wash to give it a deep clean blast..

OK will try that! I think I need something to "re-black" it afterwards though, if anybody has any ideas...

I have always used Renovo products to keep my Hood in good condition. The pack contained a cleaner, dye and proofer. I've always found the colour to last well, but then recently we haven't had too much sun to bleach anything, but plenty of rain, and it hasn't washed it out either. If I remember correctly, they do a number of colours, my son's Ford ka convertible had a roof that resembled a lawn and i was impressed after a good clean how good that came up.
