What is the difference between a truss roof and a cut roof?
Trussed Rafters may have a lower impact on the environment as they are manufactured off-site to reduce the amount of waste created whereas a cut roof, by its very nature, is hand built on site creating waste which will need to be removed when the project is completed.
