spent sat. on my tin roof painting it black. i primered it last week end. suckee!!! my house just got this new crap called Ondura which is just like tine roof stuff-the wavie kind- except made out of like 3-16's inch thick roofing paper. you can walk on it too. i got it at lowe's but they know nothing about it, and cant do take-offs for you and it takes a week to get anything from the factory. it looks great. the guy still isnt quite done with it yet, has to put the ridge vents on-which are reason enough not to get it, as well as the metal flashing going around the edges. do NOT buy this stuff and you have a great time! you can just put 3-tab over the told stuff if it's flat.
