roof

Hello, We’re figuring out the design for our crown roof - something like the attached image, where we have a flat part on the top (with appropriate fall to stop water pooling), and then it would be pitched on three sides. Would this kind of roof be better as a cold roof or warm roof? I...

Hi there, I'd really appreciate some advice. We've just had a dry ridge system installed (previously wet ridge with mortar). This was to fix a leak near the chimney but the roofer said the ridge tiles were in a bad way and they were the likely cause and suggested a dry ridge system (mortar was...

Morning all, Next problem to tackle. Old chimney was rendered years ago ( not sure when) and I had it stormdried 2 months ago but water is still tracking through the brick work and then running down the face inside the loft. 100% sure it is not a problem with the roof all soakers in place...

Single story extension is leaking in heavy rain - we have a flat ceiling inside and in heavy rain both spotlights are dripping heavily with water. One towards the back of the extension wall and one towards the front. We’ve also got 2 other wet patches. We’ve been on the roof and inspected the...

Hello, I’m trying to design a crown roof for our rear extension with two of the sides at 270cm (to reduce light impact for the neighbour) and 300cm at the other two side (to allow us to have higher kitchen units). This creates the problem of what to do at the transition between the heights. I’m...

Hi, Since moving into my house last year I’ve had a constant problem in the colder months with my felt being wet through on the underside and droplets of water dripping onto my insulation. I have had a gable vent fitted, lap vents installed, ridge vent fitted and the house already has vents in...

hello! Could someone advise me on the best way to repair my garage roof. Flat roof. - felt with stones. The flashing into the gutter has worn, which is now allowing a small amount of water into the ply underneath. Looking for the best way to seal.

Hi everyone, I noticed water dripping from the corner of my Velux roof window in my loft extension. I've read on this forum that water around Velux windows is common, but the leak might not be due to the window installation itself. However, I found a tear in the Velux flashing. Does anyone...

Hello Previous owners had an extension built that basically acts as an independent structure with it's own boiler, consumer unit etc... and it's own roof. Didn't think anything of it when we moved in 2 years back but the valley where the two roofs meet has been a source of leaks, partly due to...

Hi. I’m up to speed with cut roof construction from previous threads. Looking for advice/opinions on specific situation. Existing garage ceiling joists 47x100: 6m span on wall plates either end. 400 c-c over 3m run Existing binders 47x125: at 1.5m spacing perpendicular to joists. One end...

Hi all Hope you're well. I've just had my house re-roofed (new membrane, new battens , new thin edge sandtoft concrete tiles, and new dry ridge system). Following rain, the wooden rafters are getting damp in some areas (always the same recurring spots). When the rain stops and we have a dry...

Hi my tenants have reported a leak from the window at the top of the frame, 2nd floor. Also on the ground floor window as well, as circled on the image. I think it might be coming from the valley or something but not sure. I should have a roofer going to look at it tomorrow, but want to make...

Hey folks. We've had issues with leaking around this bay before and had 2 different roofers out to do repairs in the last 2 years. The most recent being this repair to the valley, which I've never had much confidence in (the roofers seemed more interested in trying to sell us a new roof than...

We have a problem with white mould on our rafters, which has been put down to poor ventilation. I am hoping for some advice on how to improve our situation ... This is a late 19th century terrace house with a London pitch or butterfly roof, which gives us two completely separate, shallow loft...

My parents had their flat-roof fiber-glassed over the summer. Fiberglass was applied over existing roof. Contractors drilled into the existing roof to fit the battens. The window was also replaced. When it rained the roof started leaking - small leak at first (above the window). The leak is...

Hello, I have a small business that requires customers to sit outside, I have taken on a small property which had a roof erected in the garden which was perfect. Since I moved in and signed the lease, I found out that the roof that was erected by the previous occupant did not request planning...

Hi, I have recently put proctor roofshield breathable roofing membrane on my 15 degree pitched roof extension. Over the last week with the heavy rain I have noticed water coming through the membrane on to the roof rafters as if where I have nailed the battens to them. The inside of the...

After every rain I can see damp patches on the chimney breast in the bedrooms of my first and second floor. had several roofers come round to quote but none followed up and one point blank told me that he "didn't fancy it" because of the height. In the end I had someone come in and but "a...

I am boarding some of my loft for storage and am a bit confused on the best way to strengthen the existing joists. I have read conflicting advice, some say you can add additional joists on top and perpendicular to the exsting ones. Others say do them parallel and some say increase the height of...

First post so please be gentle :LOL: I’ve recently bought a house and wanting to use the garage as a workshop / gym. The roofing membrane looks pretty nasty from the inside and there’s a few holes, plus it’s rotten away by a few inches at the gutters. I therefore want to replace it (myself)...
