New flat roof required. Anyone know rough price?

machofairy

We are in the process of buying a house. The attached garage needs a new flat felt roof. Its size is roughly 13' x 7'. Anyone know what price. roughly? I seem to be unable to find an online quote without the roofers actually visiting the site.

Thanks in advance.

Rather a small garage - there aren't many cars that are going to fit into a garage only 13ft long. I would allow for £1000, absolute maximum, depending on the felts used. Unlikely to be less than £500.

Not sure if it's any help to you but recently had the flat roof of my extension done, approx measurements 24' x 13' & it cost me £1200. None of the timbers needed replacing, which would have cost more had there been any damage to them. I know I got a good price as I was expecting the cost to be around £1800, but lucky enough had this guy recommended to me.

My mum bought a bungalow in December last year and during the recent gale force winds her garage roof (which was joined to next doors) decided to visit the back garden. When surveyed the surveyor said some minor maintenance had been done at the edges and it would require replacing at some point in the future. The roofer that fixed it said the reason it flew off was that it was not sealed at the edges only tacked.

I dont know the actual measurements but it is a standard garage but in a block of two - her half cost £799 including VAT to reroof. Dont know if this was cheap or expensive but its gone through the insurance anyway.

If I were you I would get a couple of roofers round to give you a couple of quotes - they should do it for nothing if you tell them they will get the job once you purchase the property.

of the wall idea but it might be worth looking at a grass roof, its basicly a layer of felt and tar with a thin layer of soil and a special type of grass.

the reason i say this is its tough as hell, lasts for decades with almost no maintenance, adds to the waterproof charactorsitics which a flat roof will really need and personaly i think looks cool.

the main problem with flat roofs is they need replaced almost every 10 years, the constant laying water often premiates the roof anyway and a generaly a stupid idea, the only way i can think of solving the issue short of putting an angle on the roof is to have a layer of turf that absorbs water and distributes it assuming the beams can support it.

How do you mow it?:rotfl:

dont need to, the strain of grass you plant is selected to only grow upto 4 inches, looks a little shabbie but i think well cool.

ken livingstone was going to give out grants in london a few years back as they reduce air polution and water run off.


ps im not some random hippy, ive 2 motorbikes a big old car and pickup truck, i'm not even sure i belive in global warming but i quite like te efficent idea of a novel building technique.

my roof is about the same size as yours.
i priced up all the stuff from wickes to do it myself. then found a chap who did it for 250 quid. with the bitumen burner kettle thing in my front garden.

great job, never leaked since.
thats about 2 or 3 yrs ago now.

Thanks all. Anymore inputs will still be welcome. So, apart from ormus's pricing, all other prices would include labour, I presume. I'm afraid I have smooth hands and not used to nor any good at manual diy work

I'm in exactly the same boat as you - i think....

We've been told the place we are purchasing has a leaking roof (don't know how bad) and it is on the end of the garage block. It's about 1.5 times the width of a standard garage though.

Not really sure of costs or what is required, but talking to relatives who have done this before - they have recommended replacing the wood with Waterproof plywood, and then getting it re-felted etc. Costs of up to £1000.

However, until we move in, we don't know if the leak is bad enough to warrant replacing the lot - it could be possible to repair the damage.

Only other issue is how it will join the garage next to it... we assume the felt will just overlay the next door neighbours.?

My flat roof sprung a leak last night. This chap you found wouldn't happen to be in North London?
