Preserving / re-roofing a shed
Discussion
Our shed has suffered some neglect for the last few years but is basically solid.
Problems are:
It was painted but has peeled pretty badly, so I'm going to sand it off and paint it with some kind of preservative but I'm wondering what would be the best stuff to use - Cuprinol alone do about 5 different things and I have no idea what the difference is!
The felt on the roof is in poor condition and needs replacing. Am I right in thinking it's just overlapped felt side to side held down with galvanised large headed nails and wooden battens, possibly sealed with some sort of bitumen paint on the joins?
Some of the wooden battens under the floor look like they may be suffering from rot - any tips for replacing these without dismantling the shed? (an option already explored and discounted!)
Cheers!

Get the phone number off one of the tins and ring their technical department, they'll advise the best one for your situation.

Yes, start at the bottom, overlap the felt by about 4 inches, use ELH (extra large head) clout nails, felt adhesive as well if you like. Using wooden battens will help spread the wind loading on the felt, preventing it lifting; just watch out for water "ponding" above the battens.

That will depend on how they're fixed to the sides of the shed. You may be able to saw odd boards out, or you ma have to take 3 or 4 four out to be able to replace one.

Overlapped felt will do the job. No need to stick the overlaps down, just use the large head galvanised clout-nails.
Purchase new floor support battens (tantalised) and slide them in next to the old ones.
The modern equivalent of creosote will probably outlast any of the new water based variants for the exterior of the shed.

Unless you sand right back to the bare wood, a stain will not be much use. If previously painted, sand back to a sound surface, use a decent exterior primer, undercoat and top coat.Purchase new floor support battens (tantalised) and slide them in next to the old ones.

Wickes' do a 'How to' leaflet on re-felting which also explains what their various offerings are and (roughly) how long they will last. As usual, the better the system the longer it will last.
The summerhouse I did last year is supposed to be good for 20+ years, a bit excessive for a shed perhaps!
