There are several technical and functional reasons to carry out upstands and flat roof sections separately, to ensure good durability and watertightness.
- The stresses and movements in the roof surface and upstands are different.
- The techniques for installing the roof surface and the upstands are often different (for example, partial versus full adhesion).
- Upstands, like details, require more careful installation. A separately applied upstand ensures better watertightness at critical connections, such as roof edges and drains.
In summary: executing upstands and roof surfaces separately prevents cracking, improves watertightness, and extends the lifespan of the roof.
