Guys, anyone able to offer any advice on this please?
It has been brought to my attention that I may be breaking an insurance policy by not having a flat roof at one of my properties inspected annually and when it needs replacing it’ll be expensive because of the asbestos that will have to be disposed of.
I am told that there is a modern coating that replaces felt and tar and lasts forever instead of 10yrs.
I know naaaaathing!

My parents have a flat roof on their kitchen extension, and it started leaking. They had a chap round who coated the whole thing in fibreglass, so it's one big fibreglass sheet now. It's quite thick and seems very sturdy and should last "forever" (we hope).
Not sure if it's forever, but certainly in excess of felting. The guy who quoted for us was talking 15-20yrs.I used to be a lab technician last year at a dangerous good test station, but due to the recession I have now found myself with another employer who specialises in flat roof membranes. .
If you need any info, electrical testing, types of roofs, leak finds pm and ill try my best to solve your problems, hey even inspect them free of charge (location pending) for fellow ph's. Hope this helps!

What are peoples opinion on "Rubber Bond" type flat roofing. Better than felt? Any better alternatives? It's for a large bay window if that makes a difference.
Rubber or EPDM /TPO roofs are ok if they are installed by a competent installer - I have seen loads of these fail through poor workmanship.blackcab said:

Rubber or EPDM /TPO roofs are ok if they are installed by a competent installer - I have seen loads of these fail through poor workmanship.Different roofs = different membranes. They all have strengths and weakness, but if applied correctly and to manufactures guidelines should last 20 years +.
However if they do leak, which does happen, if not maintained correctly or damaged due to impact or weather.
-I can't stress this enough, follow repair methods set out by the manufacture. I've seen a lot of cowboys f
k up easily fix-able single ply roofs! Go with a contractor that is registered to work with the roof membrane you have down! Hope this helps! Mtb

The GRP roofs are pretty good, down side to them is they are extremely slippy when wet or damp and they require that the roof is redecked out in OSB3, so this is then classed as new roof and not a repair, on certain roofs Part L of building regs would come in to effect - the roofs do not breathe either so any moisture trapped is there for good rotting your timbersswiftpete said:
Epdm has a life expectancy of 50 years plus if it's installed correctly. Fleecebacked EPDM is better than the firestone stuff which is essentially the same stuff, but it doesn't have a fleece so doesn't stick down as well and will show up any imperfections in the roof deck. If you have a smooth surface it's usually possible to stick directly to it, if not then either overboarding with 11mm OSB or completely ripping the old roof off then replacing with 18mm OSB is recommended.
Quality all depends on the fitter though, I've seen loads of epdm roofs fitted badly, again usually with firestone as you can buy it off the shelf with no training required so any old gippo can claim they know how to do it. Best bet is to get a certified fitter who's been doing it for a while.
For the poster who asked, bay windows are not a problem with EPDM, they're usually tongue and groove decking so it's a pretty easy job to strip and recover them, usually only a couple of hours work so shouldn't cost a lot.
