Anyone know anything about flat roofs? My new place needs felt and insulation put down. I'm looking online to get a couple of quotes but you hear that it can be a bit wild west with some of these companies. Anyway if you know a reliable roofer for south London i'd appeciate it.
Thx.

1. They need a tar boiler to seal the felt - serious fire risk. The more cowboy the roofer, the more you should worry
2. They are notoriously difficult to repair/seal because water does not drain off them so you get "ponding" of water which then finds minute cracks/holes in the seals between the felt sheets and leaks. I had one re-felted somewhile ago. The bloke could not get it to stop leaking. In the end I did a deal with him whereby I had a sloping roof built and he contributed to the costs.
3. Because of 2. above you need them to give you a guarantee (10 years min). Problem is the more cowboy the firm the less likely they will be around to honour it.
Hope that helps.
Its the normal thing for flat roofs. Felt with a mineral finish. I owned a shop with a flat roof and I can assure you it was felt over a timber decking. I also had a house with a flat roof extension which was felted. What you are talking about is felt for under tiling.
There are new products out including single ply membrane which you would be a 15 year guarantee these are usually done with a heat welded gun.
Is there already insulation on your existing flat roof?
Got a mean selection of First Day covers plus my pride and joy - A Stamp from the time of 1966 with "England Winners" embossed on it. Anorak anybody?
