I have a business and the roof is not all that good. So i decided to get a rubber roof. One of the estimaters told me that theirs only one main producer of rubber roofs and they sell it to other companies who will put their label on it...is that true? And what is the best, strongest, thickest rubber roofing out there? And what is the best way to put a rubber roof down, torch or mop? Some people told me that torch isnt all that great while others say using the kettle isnt fantastic either. Im assuming when they say asphalt, they mean the kettle. Need help!
