Why Proper Roof Drainage Really Matters

The force of water is a mighty powerful thing. Ponder over the depth and width of the Grand Canyon for a moment. And then turn your attention to the flash floods after increasingly heavy rains as our atmosphere warms. Our homes take a pummeling, although not on the same scale. We need proper roof drainage to lead the water away.

Proper Roof Drainage Is Not Always That Simple

Many calls for assistance to our company follow clients’ concluding all is not well with their homes. Damp on ceilings and walls are a common first cause, but careful inspection may lead to signs of damage to foundations, and permanently damp soil in the garden nearby.

As roof design becomes more complex, multi-level structures with split levels, gables, patios, and dormer windows can increase catchment areas quite considerably. Yet some roofers still believe a single-row of eavestroughs is sufficient. How wrong they often are!

Things to Remember with Eavestrough Systems

EAVESTROUGHS AT EACH LEVEL

Multi-level homes should have eavestroughs at each level to take their water safely away. The alternative of creating a cascading waterfall simply will not work in heavy rain, and there will be local flooding.

MANAGE THE WATER RUN-OFF

Proper roof drainage includes the next step in the process. The water must enter a proper drainage system, as opposed to pooling in flower beds and on lawns. You should not discharge the water irresponsibly!

TAKE CARE WITH RAIN BARRELS

Best Can wisely points out that rain barrels do not have infinite capacity. While this may sound obvious, we sometimes root-cause damp to these storage devices overflowing near foundations. They need careful siting and planning.

WATER RUN-OFF PROVISION

An eavestrough system should discharge its contents via drainpipes at least six feet away from the building. An integrated approach should direct this into drainage systems to prevent damp at the lower walls and foundations.
