Bobby Jim Posted March 29, 2020 Report Share Posted March 29, 2020 Does anybody know of a good resource for synthetic slate (rubber tile) roofs? Or does anybody have experience with them curling? I've got a roof that I suspect is curling due to a material defect, installation defect and/or poor ventilation. Thanks. Quote Link to comment Share on other sites More sharing options...
Dave K. Posted March 29, 2020 Report Share Posted March 29, 2020 (edited) Bobby Jim I would recommend looking at the installation and spec sheet on this type of product from a manufacture as noted below in the attached links. It appears from this source below a synthetic shake has a 50 year +/- life span. Installation is always a great place to start..... https://www.bravarooftile.com/wp-content/uploads/2020/02/Brava-Cedar-Shake-Installation-Manual.pdf https://www.bravarooftile.com/wp-content/uploads/2020/02/Brava-Cedar-Shake-Spec-Sheet.pdf Edited March 29, 2020 by Dave K. 1 Quote Link to comment Share on other sites More sharing options...

I don't see a lot of them, but every one that I've seen was failing in one way or another. (There are almost no real shake roofs here, so no reason to have fake ones.) I also know that ventilation has little effect on the surface temperature of a roof (usually less than 5 degrees) and, despite manufacturer's claims, has little bearing on the overall performance of roof coverings. And that's about all I can contribute. 1 Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted March 30, 2020 Report Share Posted March 30, 2020 Plastic slates, aka mud flaps. Curling is very common with the older products. The manufacturers have claimed it's not a defect and is a minor cosmetic issue. A step was added to some installation instructions. The installer should bend each individual slate down at the butt end and corners before installing. I don't think this helped for the long term.

Mundo Inspector Posted April 13, 2020 Report Share Posted April 13, 2020 It's a common problem with some brands of composite slate. What Bill said. The common fix is double-sided tape. Quote Link to comment Share on other sites More sharing options...
frank hogan Posted June 16, 2023 Report Share Posted June 16, 2023 my rubber slate roof is 17 years old. curling is now a major issue. this is due to the installers did not properly follow the manufactures guidelines.the curling has occurred in sections while other sections of the roof are still in perfect form. also the lack of proper venting is common in hip roofs. Manufacturer 50 year guaranty was voided. however with additional venting and tape hopefully I will get more years out of it. Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted June 17, 2023 Report Share Posted June 17, 2023 I think the venting guidelines might only be the manufacturer's tool to deflect claims. Here's a better application - plenty of venting. 2 Quote Link to comment Share on other sites More sharing options...
