Many homes and commercial buildings have steep slope roof structures where asphalt shingle roofs, metal roofs, slate roofs, shake roofs, or tile roofs will perform well and last a long time. But sometimes they have a slightly lower pitch and need a low slope roof covering like a single – ply membrane. And other times these lower sloped roofs are porches or room additions attached to a steep slope roof.
White TPO membrane roofs are driving the market along with E.P.D.M. and P.V.C. membrane roof systems.
So what if you have a low slope roof that is just sloped enough that it is visible from the ground or a window above and you don’t want a regular membrane roof for aesthetic reasons? A practical, cost effective and aesthetically pleasing option is a granular surfaced modified bitumen membrane roof. I personally like the self adhered type.
By” granular surfaced,” I mean it has the same surface as a shingle. It is covered in granules and comes in different colors. It comes in a approximately 36 inch wide roll and sticks down to the plywood roof sheathing. I recommend one, or even two layers of self adhered base sheet be put down first for best performance and longevity.
This product comes with up to a 20 year warranty and you can closely match your adjacent shingle or other type of roofing with it. I prefer to use CertainTeed Flintlastic SA Cap as a brand. It comes in 7 colors. This system is not for a flat roof. You must have positive drainage to use it. I would not use it if there is any ponding or puddling of water on a roof after rain.
Please call me if you want to talk about this roof system or any other.
