Above is a picture from a house in Renton that we just finished installing white colored TPO. We offer both TPO and PVC for low slope and/or flat roof homes. This is an alternative to traditional torch down, hot tar, or EPDM roofing. Both TPO and PVC are low cost, durable and have a 15 – 20 year life span. Our preferred brand for low slope roofing is WeatherBond.
