Help me fix my leaking shed

[WhatWouldCaitlinDo]

Our garden shed (classic wooden type like this) is leaking from the roof. Does anyone know how we can fix it ourselves? Our new falling down house and garden need lots of work and we're trying to do the non-expert jobs ourselves.
Thanks!

new felt.

shed felt is different from house roof felt as it has no tiles to protect it from the sun. Green Mineralised felt is good.

you will probably need some galvanised clout headed nails, and some tilers battens for the edges and joins to prevent the wind flapping it. It may help to drill a small pilot hole for each nail to prevent splitting.

when you take the old felt off see if the roof timber is rotten. If so, put WBP ply over it before the felt.

apply the downhill piece first so the uphill one overlaps it
