Hi Wonder if someone can give me some advice. We had a new flat roof installed last year and it looks a good job by a reputable company. We discovered a leak recently and they come to look at it and added some sealent over the existing seal. I'm a bit concerned this isn't the best remedy if the...

Just moved in to a 1950 build house and was hoping someone could give some advice. I’m a long time reader of the forum but this is my first post! I’ve started working on a room in the house which I believe used to be the garage - which has been converted into a room attached to the house at...

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...

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...
