Shed Roof

khaldrogo

Good evening.

I built a block shed/workshop (22' x 12') about 8 years ago. I put a flat felt roof on it as it was the cheapest option I could do myself.
It took about 6 years before I realised I didn't have enough of a slant on it to properly drain the rain water and as a result water started pooling and eventually leaked through.
I tore it up last year and put a new corrugated bitumen roof on it. I tested the new slope and the water ran off it very well.......until about 6 months later and now I have the same issue of water pooling and leaks.

I am pulling the whole lot off again Saturday week but I'm not sure what way to go in terms of the new roof.

I want to stay down the bitumen corrugated route but do I go for the traditional A frame approach or just built a new flat type frame with a bigger slope?

Money, time and expertise are all not in my favour on this.

A bigger slope with a fiberglass finish.

2nd for fibreglass.

What's the slope and how much do you want to spend?

Post up a pic. Have had this issue, simply got wedges cut, screwed to joist, to give bigger fall....

The current slope is about 2%.

I want maybe a 10% slope and ideally want to send as little as possible. I am hoping to reuse as many of the existing corrugated ieces as possible

Grand, pull the roof off and just increase the slope, put the old roof back on. Are they full length sheets across the roof or have you joined them in places?

Interested in Fibreglass myself, is this a good guide?

Hi, roofer in the extended family, he has removed a lot of fibreglass roofs in the past few years, some only down two years. He wouldn’t recommend it at all.

Plus fiberglass is crazy money for a shed roof

That's odd. It sounds like the onduline has sagged. Is it properly supported?

Don't mind fiberglass, get on to Dungdeal and find someone selling cladding (even cladding seconds) and use it.

Fine job for a simple lean to roof
