torchdown roofing question

i was looking at the torchdown roofing product at Home Depot the other day (can't remember the brand) and i was wondering if the upper surface will get a black powdery coating as it weathers. the top surface of the torchdown had a fairly glossy surface with pretty much texture from the reinforcement fabric. the reason for asking is that i have an roof area (nearly flat) that is accessible to people walking around, and i was thinking about covering with the torchdown to make the surface more resistant to damage. it would be a problem, though, if black residue would be tracked into the house. I'm thinking that the mineral faced torchdown would also cause grit to be tracked inside. the roof area is now covered with modified bitumen (fairly new).



thanks for any input. bill

I'd cover the torchdown with white graded gravel. The rain will keep the gravel clean so not to worry about tracking. It will also extend the life of your roof for years.

They should be painted to reduce the suns deteriorating effects., I dont know what colors other than white and silver are avalaible but a top coat over the silver could be a high grade Latex house paint, any color.

I would think that the gravel would put holes into the torch-down material. Especially if people are going to walk on it. I would (and did) coat the torch-down with an aluminum paint like what is used on mobile home roofs. Seem to hold up very well.

First off - I'm no roofer although I have instaled a feww torchdown roofs and others as well. Torch down comes with or without granuals. The type without should be coated after install IMO. Thats more for UV than anything else.

I thought Modified Bitumen WAS torch down.

If you want to walk on the thing, I would build a deck above.
