Hi all, ive moved into a new house and found the garage roof is leaking, so i've got quotes to get this repaired, turns out the previous owner has been doing patch up jobs for a long time AND its an asbestos roof  so need to replace the whole thing. 
	 
	I want to later on down the line convert the garage into a usable room one day. So want to do this correctly. I'm wondering if anybody can recommend which would be the best option for the new roof, while still being cost savvy of course, as each builder is of course saying the one they want to install is better than the other options lol 
	 
	The options are:
	traditional 3 layer felt roof
	epdm rubber
	fibre cement slate tiles
	profile 6 fibre sheets
 
	 
 
	It's a slightly slanted roof if that helps.
