Sikaflex 252 adhesive may be used in place of screws, rivets, welds, and other fasteners. This is a polyurethane adhesive that seals and bonds in one to step to provide high strength elastic bonding. Suitable for a wide range of substrates.
Sikaflex 252 bonds and seals at the same time, offers excellent gap filling capabilities and compensates for loose tolerances in the building process. Sikaflex 252 exhibits excellent Green Strength and that means reduced clamping time. Some surface preparation is generally recommended for Sikaflex 252. Sikaflex 252 is sandable, paintable and NSF approved for incidental food contact.
Particularly suited for bonding of metal of wood, trim, molding, styling elements, structural bonding of large parts including sheet metal and composites including large panels. Bonding of FRP roofs, sandwich panels and walls. Sealing applications especially for large joints. Replaces rivets and mechanical fasteners.
Wood, primed metal, and composites.

I have used this to bond sheet steel to sheet steel. It is awesome. I'll use it to bond the panel anchor strips to my Jaguar XKE bonnet. My test strips (after 3 years) are as solid as ever. The Sika 252 is forgiving and easy to work with. It holds paint really well (automotive). Use a high-leverage caulk gun (yes they cost more, but you will thank yourself) and you will have no problems dispensing the Sika.

The product holds well but is hard to squeeze by hand through a caulking gun. So I found it difficult to lay a good bead.

Used this to attach two Renogy Cable Entry Housings to a vertical surface. Company suggested it as the only way to attach the housings. They are firmly attached. I used about 10 milliliters of the adhesive. It would be nice if Sikaflex offered a much smaller quantity.

We use this to adhere trim onto exterior of vehicle bodies. Very good bonding agent with little hassel.

In a word: PROBABLY would work in rubber roof app. Make sure both surfaces to be bonded are clean and dry. This step is often over looked, and is critical. The solar panel supports we bonded to a wood shake roof were later removed to relocate the panels and were done without damaging the supports or the roof. Held up in temperatures on roof of over 130F and high winds of gusts to 50 mph
