Can someone explain the different thickness and weight per square meter? I'm trying to figure out what's the right one for a flat roof on an apartment building so I can make an estimation on how much money it will cost me in materials alone.Also feel free to mention any other material expenses besides the felt itself.
>>2851289What city, what is the build up of the roof, what is going on at the edges
>>2851297What do you mean edges? The roof is concrete slab and has like 70cm sidewalls.
