Hi guys have a small car garage on the new house. It's a flat roof with torch on with stone drainage. The roof is full of moss and quite unsightly. Any other products options out there? Looking to keep the roof flat to keep cost down

 

Fibreglass flat roofs are the way to go i reckon. Most come with a 25 year guarantee also

 

You want to do it in Sarna it's really good gear will out last everything else

 

I used profile sheets plastic coated, I did put about a 6 inch drop front to back to help stop standing water, lasted very well been up about 20 years now only issue I had was washers under roofing bolts cracking and leaking slightly a quick coat with flexible mastic has put a stop to that.

 

Any pics? do you get condensation building up?
