flat roof

My parents have had a porch built with a flat roof cut into the existing pitched roof. The walls are damp externally so I took a quick look at the roof and thought it looked rough. The dampest part is to the left of the front door. The builder has come back and squeezed a tube of silicone in...

Hi All, We have a flat roof over the porch, and there has been some water getting in over the past few weeks. It is a 50s concrete flat roof, and although you cant see from the pictures there is a drip groove which does filter a lot into the guttering. There is still a fair bit still working...

Ive had a quote to replace lead which is between the house and a flat fibreglass roof (which is also a fairly large balcony area). The original lead, I am told, was installed wrong, as it wasnt split in to sections to allow thermal expansion and contraction, so it has split. It also seems to...

Flat roof is in need of some tender love, confused about all the different products. Have tried some before, esp the paint-on ones (Thompson, Acrypol,Cromapol), but not sure they are that effective, esp as they are only a thin layer of paint. Spotted a video about Watco Roofite, not in typical...

Hi, I've recently had a flat roof (warm) installed by a local contractor, who used 100mm Kingspan over the main deck, followed by torch-on felt. BC now advise that the insulation is too thin: 100mm gives 0.22W/m2K, requires 0.18W/m2K. Is that reasonable? What is my recourse? can anything besides...

Evening All, Iv recently had a new flat roof replaced and was wondering if the attached pictures are the norm in how there is a gap between the edge of the flat and the facia board. The wood is visible. I was told the was something called a drip ledge or something along those lines. Any help...

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?
