Choose siphonic drainage when you need to drain large rainwater volumes from flat roof tops quickly and efficiently. Typically used on large industrial and commercial roofs, our siphonic system is a cost-effective substitute for traditional systems.Smaller pipe dimensions, fewer roof outlets and downpipes, and shorter total pipe lengths all reduce installation costs. Because lateral pipes need no gradient, you maximize the use of building height too.Low slope roof drains are indeed subject to clogging that in turn can lead to serious, even dangerous conditions such as:
- Roof flooding, weight and structural failure worries, an occasional roof collapse, particularly if the flooding and weight on a roof are combined with structural damage from rot or insects as may have occurred on an older building or one whose roof had a history of leaks
- Roof overflow sending water into nearb
- Inspect the current roof drain(s) and the drain line through the building for leaks and assure that the materials are in good condition;
- Inspect the roof surface and roof drains on a regular schedule to find and clear away any debris clogging the drains; just how often this is needed depends on local condition such as the rate at which debris accumulates on the roof.
- Roof leaks – leaving standing water on a roof not designed for that condition invites roof leaks and failure both from the continued presence of water and in freezing climates, from further damage to the roof covering from freeze-thaw cycles.
- Building interior flooding also is more likely when a roof drain pipe passes through the building interior rather than outside the structure; a freeze-up or clog followed by freeze-up of the roof drain segment that is at or close to the roof top leads to leaky or burst drains and building damage.
