What does a full low-slope roof installation include in Jeffersontown?
A commercial roofing contractor installs the whole roof assembly, from the deck up to the edge metal. On a low-slope building, the layers stack in this order:
- Deck of steel, wood or concrete
- Vapor retarder where the building's use calls for one
- Rigid insulation boards, sometimes tapered toward drains
- Cover board that shields the insulation from foot traffic
- Membrane of TPO, EPDM or another single-ply sheet
- Flashing at walls, curbs and pipes, finished with edge metal and gutters
Each layer has its own job. Changing one layer, such as adding insulation thickness, also changes curb heights, parapet flashing heights and the fit of the edge metal.
