My 12' x 10' garden shed/workshop is leaking - for the umpteenth time. Several times over the last month I've plastered black sticky stuff over the seam where it occurs. But somehow water is still getting in. This is the second felt roof I've had in 12 years and prompts my first question.
Q1. Why aren't shed roofs simply covered with some robust plastic sheeting, cut to size and nailed or glued after tucking around the edges?
I'm not a confident DIYer so want to get someone to fix it. But so far all the companies I've been looking up online seem to describe 'felt' in the context of sheds and flat roofs.
Q2. How/where can I find someone or some company to quickly cover the existing old felt roof (slightly sloping) with a permanent, reliable waterproof sheet of some sort, whether plastic, rubber or whatever?
Q3. Are there any downsides to such an approach please.
I need to get something done urgently, as the shed is used for my electronics hobby. Latest project damaged overnight.
Any practical advice would be much appreciated please.
