Shingles do not work well on Flat roofs Knoxville, TN.
This home has shingles over a flat roof. Shingles and metal roofs are not designed to perform well on flat roofs. This led Litespeed Construction to recommend using a membrane roof like TPO or EPDM to cover this flat portion of roofing.
The shingles and metal are possible to work just fine on flat roofs, there is also a chance that they leak and have issues. Membrane roofs are better for low slope commercial and residential roofing systems.
