Hi Folks.
Apologies in advance for this not being a workshop build, or indeed woodwork related, but since I joined this forum a few years back I have been very impressed with the knowledge of the forum members and I can't think of a better place to get advice.
So on to the problem.
We have a bomb shelter in our garden which was converted into an office for my wife. The problem is that there is a little water ingress and we would like to improve the roof to try and fix it. The shelter is built in brick with walls about a foot thick and a concrete roof. There is no overhang so any rain just runs from the roof and down the walls. I was wondering if some form of roof construction on the top of it with felt or EPDM covering, and with an overhang would improve the situation. Trouble is the building is 3.3M long so not a simple 'one sheet' size, and despite being a member of a woodworking forum my skills in that department are seriously lacking!
The concrete roof slabs do have a couple of cracks which don't seem to go all the way through (they are totally solid) and the pointing on the walls has had ferns growing in it. Despite my wife liking the cutsie aesthetic I have finally persuaded her that we have to remove the ferns and fix the pointing which I am guessing will help a lot. But will that be enough?
So what would you do, bearing in mind a preference for both a low cost and low skills fix?
