Modified Bitumen
One of the most durable and best roofing applications on flat roofs is Modified Bitumen, which is typically laid over other layers of fiberglass or base material, thereby creating a redundant system over a low pitch roof that has to have multiple layers fail in order to leak. There are four ways that roofing companies apply this material: rolled while being heated with a torch, adhered with either cold or hot mopped asphalt, and finally adhered via a self-adhesive peel and stick application.
PROS:
- Very durable / multiple layers
- Long life cycle (20-30 Years)
- Lowest probability of leaks
- Puncture Resistant
- Low Maintenance
- Very walkable
- Multiple color options
