I installed Cemwood woodfiber-cement tiles on my roof 10 years ago. It has been the subject of a class-action suit which has been settled. The exterior coating of the material started flaking and the tiles absorb water. This year I’ve noticed water seeping through most likely some nailholes and staining several rafters . Short of replacing the entire roof, I would like to do something before things get worse and water starts dripping through.
Has anyone any experience with DryLok? Will this work on a cement roof? Will intense sunlight during the summer cause any deterioration of this application and shorten its lifetime? How often might I have to apply this?
Any experience with any other kind of water proofing material (epoxy, latex paint, rubberized paint?) that might be worth trying?
Thank you all for your opinions.
