The company that built it pulled out of the project neat completion, it was really weird and I don't know why they didn't finish it but I get the feeling that they misquoted and were just cutting their losses at...

    Hi Guys, new to the forum and DIY in general. Note, I have no DIY experience at all, except for assembling home furniture. I had a garden building built in 2018, and now the flat felt roof has already failed and caused a massive leak inside the building. Large puddles form on the roof, and...

    EPDM: rubber4roofs or firestone?

    I'm reroofing a porch roof, approx 3 square metres. Planning on 18mm ply (joists are sound) with EPDM on top. Is it worth spending time and money getting firestone rubbercover, or would something generic like 1.1mm EPDM with adhesive from rubber4roofs be as good?
