Yes French roofers always say they have never used roof felt because its good for circulation of air......Yes this is ok but only really if your on the coast of the south of France where its mostly hot all year round. If your in an area of Dordogne or Limousin then you will need felt on your roof no matter what they say. When i came to doing my roof i got a few roofers in just to see what kind of answers they would give me and what kind of price. It was a joke ! i was quoted 14,000 Euros and 12,000 to have a new roof fitted (With Out Felt) from two difference companies and he told me it would take 2 weeks to complete. I have worked on roofs before and even though i am not an experienced roofer but yet it isn't rocket science ! my roof would only take 4 days work with two guys and it was a good sized cottage ! I bought Tyvek Felt Membrane from the uk i bought 2 rolls at £90 each ! its the best membrane on the market today and french roofers havent heard of it because they are 25 years behind !!! also 25 years behind in giving quotes !!! no rush for them because they charge scandalous prices and don't have to work as much because they are loaded from robbing all us brits..... My materials i bought from Bricoman for 1,600 Euros that was for the tiles, Batons, nails, Ridge tiles and all the other small accessories to complete the roof. If i had bought the materials from the uk it would still only cost me £2,000 for everything ! so french materials are also much cheaper but labour costs are a rip off ! The roofer added like 50% price on every item i would have ordered...... You'r best option is to do what i did ! get in touch with a small roofing firm in England pay for there flights over put them up in a caravan feed them keep them in beer pay them cash in hand and you'll still be saving lots of money....and they will have the job done in no time The french think that all brits that come over are rich and won't think twice about stealing you hard earned savings for a job you could have got done for half of the price in half of the time. You should be able to get Tyvek felt on amazon french version If the French roofer has completed your roof and it has already started having problems then you should call him back and tell him to do the roof properly. They will give any excuse like Enviromental circumstances....wind Rain bla bla...... All these companies should also give a 10 year Guarantee Hope this helps
