Flat felt roof - anybody an expert?
TimC - 29/9/06 at 07:59 PM

Greetings

The house we're buying has a garage roof that is in the words of the survey is 'well beyond it's useful working life.'

Does anyone know what it might/should cost to get a new roof put on a standard single garage??

My next door neighbour's a flat roofer.

Serious, I'm not pulling your pisser, and I think you've met him

Just another resident of Wierd Avenue, Freaksville.

If it's gopt a slight slope to it (which I would hope it should!), it'll cost you some external plywood, roofing felt and some mastic sealant (wouldn't do for a house roof, but garage should be ok - just like a big shed roof)

If it's completely flat, then a bit more complex as it need to have falls to the guttering etc and be able to channel standing water away - get a proper flat roofer for this sort of thing.

Yes I know some of my neighbours have issues, but he's OK.

Sometimes it feels like Custers last stand, they'll all around me, closing in. I'm not paranoid, no, not me.

I did my shed for about £35

It's 10ft x 8ft

I put thin ply on first then , painted it with bitumastic paint , then fitted the felt by melting the backing with a small blowlamp as i unrolled it ,I have not used any nails 'cos they ALWAYS pull through and leave holes.


The felt is quite thick 3mm ish , the stuff you get from wickes / B&Q etc is rubbish go to a roofing supplier, and get pukka felt that has to be melted on , and has good protection on the top surface against the sun

Why not rip it of, sheet it with ply,if need be add run using tapered 2*2 or 4*2 (furring peices we call them) And them fibreglass it. You can get all the preformed edges/upstands etc etc from cfs (links in some recent threads). Done right should see you through the next 25 years and good experience for the locost work.

yeah , i used to do flat fibreglass roofing - about £35/ sq metre

Get some wrinkly bitumen sheet from Wickes (corrugated) and get the hammer, nails and ladder out. You can get it in green or black but it all ends up green anyway

Get a decent pitch on it and put some tiles on. Should then last a lifetime.

Thats what I did.

When were re-built our extension (about the size of a single garage) we added a couple of courses of bricks to one wall to increase the angle of the slope, new joists, ply deck, fixings and insulation cost us about £200, plus another £200 for a roofer to black (tar)and green (felt) the roof (two layers), inc all the edges and sealed back to the main house.

Yep had our kitchen refelted. Just the bitumen bit. They used the silver stuff as it refelects the sun better. They said avoid the stuff covered in grit/stones these days as in winter ice forms and can crack it.
About 200 quid to refelt probably 10 meters x 10 meters roof. That included

I phoned them up they said "is it leaking" I said no. He was rather supprised. Most people call when its too late and needs new bording up there too.
