Inner Drains

Many commercial properties employ inner drains. This has to do with positioning pipes beneath the roof or within the parapet to ensure the space is appealing without showing any pipes.

This particular draining system is positioned at the roof’s middle or anywhere the sloped drain is channeled to. Inner drains are most suitable for large roofs.

Many homeowners love to combine scuppers with downspouts to offer extra protection against water damages caused on the walls. A collector head alongside the scuppers will equally protect the walls.

  • Small-sized scuppers can easily get clogged.
