    hey All, nice website,

    recently became the owner of a 93 Adria 540 on a ducato base. there is some water ingress in an area of the roof, concealed by a cupboard. the roof is aluminium, got up to have a look and previous owner must have had a sat dish on the roof, and now the holes are filled with black rubbery stuff, probably silicon or rubber of some sort. scraped this stuff off as it looked dodgy.

    I have searched a bit and found no single conclusive answer to reparing an aluminium roof, Eternabond gets some good reviews, any other ideas?

    May do some of the seals also as they look tired and worn, any ideas for this, silicon seems like a no-go I am right?

    Any thoughts helpful. There is also a some water damage in this area.

    Many thanks

    G

    Try Sikaflex

    There is a product on the market called Sikaflex, it is an adhesive sealant, properly applied it is very very good, it is however difficult to remove should the need arise.
    Hope this is of some help.

    If its to repair holes in an alloy roof, Flashband is as good as it gets.
    Get it from your local builders merchant, it comes in a role, one side is alloy foil, the other side bitumen. Make sure the roof is dry and try to heat up the area with the wifes hairdrier or somthing similar.
    Sticks like sh++ to a salvation army blanket.

    Hadn't thought of that stuff - cracking idea - Consider it filed away for future use.

    is the aluminium bonded to the roof or floating, this will determain the type of repair you need to undertake.

    There is a product called alto lead ,ali foil one side and non settint adesive on the other.Been on the market a couple of years so more known by trade.We use it for flashing etc on roofs.
    Try a local roofers merchant and ask for a sample.This may be big enough to cover holes,but you will need a solid roller to apply correctly.
    Otherwise glue a plate over holes with silkaflex as mentioned above or another product we use and i can say does the job is called sticks like s**t.

    Hi & welcome :thumb: use Sikaflex & a bit of ally sheet -- if you use Flashband it will always bleed through any paint you cover it with -- while doing a good sealing job it will put off future buyers

    As above I would use Sikaflex , you can also get a sikaflex remover if you get it anywhere you dont want it. I use it on my boat and wouldnt use anything else.

    Yes, a lot better than silicone, easier to use as well. One thing I will say is once the tube has been opened it will only last a month or so even if you block up the nozzle so it may be wise to plan a whole day of sealing up :BigGrin: or have a sealing party with a few others.

    regards, John

    Sika make a huge range of sealing products.

    For caravan/motorhome general use look for Sikaflex 512..

    Yes it will seal / bond most things :thumb: but on roof vents I use Sikaflex and a bead of GP mastic (general purpose) because it does not stick to some kinds of plastic - sort of belt and braces :thumb: No idea why it does not stick to some kinds but sticks others so I don't take chances :Rofl1::thumb:

    You might use a sikaflex for your aluminum roofing. You better check it and personally repair it for you to make it better.
