Corrugated bitumen roofing

[Kea]

Has anyone ever used this? I have a pent shed at home that my neighbour has damaged the roofing felt on (he stacked his stuff on it when he was tidying it up on the other side of the fence and slid it around which I assume has caused the rips). The shed is in a difficult place to be able to keep renewing the roofing felt so wanted a roof a bit more long term. I'm not sure what you do with the top/higher edge if you use the corrugated roofing on a pent shed though it is against the house wall.

We've got 2 shed roofs covered with the 'stuff' and I have to say its been money well spent. They were easy to put on..took less time to do it and they have weathered well. Both roofs have been on now quite few years and they are still 'like new'.
We put the roofing over the old felt and as given generous overlap with the panels...they didn't need any 'cutting' into size neither (tried once and its 'pain' to do)

As for 'not knowing what to do'...bitumen roofing panels are quite flexible..so you could bend it up or down if fitting 'flush' is not a option. If you can apply some heat to the panel where it needs bending it will help with getting it into tight space.

We used it on our shed roof. It leaks because the wind got under it and lifted the whole roof and that loosened the nails and left holes round the 'cups' in which the special nails fit. Having said that, it is a lot easier to use than felt. You  can get shaped pieces to fit over ridges.

We have it (Onduline) on one of our chicken runs.  It's dead easy to fit, although the special roofing nails with their plastic caps are expensive.  If your concerned about the "wavy" gap at the edge, you can get special rubber inserts to put in (more costs, though).

Maybe I might put it on the allotment she's next time too. The nails look long though but worried they might come through the ceiling.

It is the cups which are important, you can use any length nail if the special ones are too long. They are designed to go through the top of the corrugations into wooden beams rather than into flat wooden sheets as in a normal shed roof. You could even use an appropriated length stainless steel screw.

...or using 'woodpallet'-type grooved nails...no wind will rip them up from woodwork..the whole roof have to come off rather than nails.
We bought the 'proper' nails (with cups) from Wickes when we got our roofing sheets and admitedly I bought too big nails that came through the roof..and the 'beams' (opps!)...I just hammered them side ways inside the shed and now I've got roofing that won't come of no matter what.. ...chicken's won't mind bit of visible 'metal work' in their home..
When doing the second shed I was bit more wiser and got right length nails for the job..
