New Flat roof cost
Discussion
Going to need to refelt my garage (single) soon and was wondering what sort of money am I looking at to get it done by the professionals? Also what felt should I be after?
In addition I have an extension roughly 10m x 7m which needs badly doing not sure on the ply condition so I guess what would it cost felt only and then if the ply is shot how much more? Again done by professionals.
Once done how long should it last? 10/15years? Live in Berkshire so the harsh coast weather will not impact it as badly as other areas.
Finally is it safe to walk on i.e. from not making a hole & talking about the new felt.
Cheers & any hints/tips welcomed.

:In before the move!:
We recently had our garage roof replaced, but didn't go for felt. We had a sealed plastic system put on, called Sealoflex, which is strong enough to walk on, and comes with a 10 year guarantee, with the option to have a new coating put on after 10 years, which extends the guarantee for another 5 years. This can be done multiple times.
From what I remember, it cost about £1100, for a single width, 7-8m deep garage. (About 1.5-2m deeper than normal. Our garage is attached to next door's garage, and they did not have theirs replaced, so this could've added to the costs. Not sure.

Did you have the boards changed too or just the felt?

Yeah, that was including new boards - the original ones were probably 35 years old, and the roof had probably been leaking for 30 of those!!! They were a bit flakey and warped!Did you have the boards changed too or just the felt?
Not sure if this is allowed, (Mods please remove if not) but this is the company I used. Probably no good for you - too far away (Cambridgeshire) but so you can see pics of the product:

Well, it did get moved then!
£1,100 for the garage? That sounds like pretty good value. I've recently had it fitted to my porch roof (about 2m x 4m) and the cheapest quote I got was £650. Let me know who did it, as I could do with my garage roof doing soon.
EDIT: Ah, a bit far from me too! Thanks anyway.

I have a few names I can pass on to you if you like, Reading based but likely to travel, Did my mums roof over the kitchen and old garage.
Got a few clients to who are roofers, again Reading based but they are good been around for years.

Why felt it again?
I recently re-roofed my single garage. But I used twin wall polycarbonate sheeting as an alternative, dead easy to cut to size and fit. I did the whole garage in about 5 hours.
plus side is that it is now lovely and light inside and quite warm. You couldn't walk on it but i'm not sure why you would want to.
Cost me about £350 in all.

For the garage - yes thats an option but dont not really wanting that much prefer the look of the felt finish (one window looks out onto the roof. Most other garages on the street have had pitched roofs put on so being flat stands out as is.I recently re-roofed my single garage.

I'd consider replacing it with a pitched roof. It may cost you a bit more now, but you can pretty much forget about it once done, unlike a flat roof. You also get the benefit of some extra storage space for the garage.
How much more are we talking about?One thing though with the garage - in time were intending on extending over the garage probably within say the next 5 years as we love the area and its a great plot + the next size house up is a huge step up vs the cost of the extension.

I've specified and installed this stuff before.. http://www.firestonebpco.com/roofing/epdm/rubberGa...
It's very good and looks a lot better than standard felt. It was about £32/m2 inc VAT & installation back in 2004. I would expect it to be a little more now. You can get cheaper but this is some of the best imo.

To re-ply a flat roof it depends on the thickness and grade of sheeting you want i.e. shuttering/marine/OSB/Moisture resistant T&G chipboard? Are you going to strip it off? Allow around £5-£10/m2 for the sheet etc, plus labour. What about edge protection (scaffold)Welshbeef said:

The Firestone stuff is guaranteed for 20 years, one of the reasons I chose it. You can get a 30 year one as well. Welshbeef said:

Not really, if you want to walk on it you have to consider whether your rafters will support you and then the felts are not designed for heavy traffic. Occasionally yes. Leave your stilettos off though and wear trainers.Cheers & any hints/tips welcomed.
Just seen your last post about building off the existing garage. What you should consider is how long you want the roof to last? If you're going to extend and rip off the new felt in 5 years time why pay for top quality 10-20 year guarantees? Consider installing the new larger rafters/floor joists now and covering it with cheap felt. If you do this I would also use the cheapest ply sheeting as a lot of it will be ruined when you try and rip the felt off. Also, do you know the foundations and walls are strong enough to support another storey? I would check this first then you can decide whether to re-roof it temporarily or permanently.

What did you do about the side bits?

There are loads of different products you can use and all have there place - Just make sure you get a few different quotes on different products, prices can vary from £25 per m2 to well over £100 per m2. I dont cover your area but if you need any advice drop me a line and I will talk you through it so you get a good job at a good price.
For a garage roof you are as well off going for a High Performance mineral faced membrane, providing the deck is suitable, On a single garage roof with a new plywood deck with firrings ( fall), 2 layer felt system, fascia board and gutter - and a proper roofing contractor I would expect £1150 - £1500 for a job that should last 20 years.
