Rain gutters are an important part of a home's roofing system. Without properly sized gutters for a region's weather elements, the integrity of a home's foundation can be compromised with excessive water retention.

Function

Rain gutters provide an outlet and direction for flowing rain water coming off a rooftop. This allows the water to be manoeuvred into drainage, away from the home's immediate exterior.

Size

Rain gutters can vary in size. If a new home is purchased, but the sizing isn't known, take a ladder and climb up with a measuring tape. Measure the diameter of the gutter. Typically, gutters range in size from 10 to 15 cm (4 inches to 6 inches).

Significance

Knowing the size of the gutters is important because it gives homeowners an idea of what kind of rain flow the assembly can withstand. If a region is prone to large rain storms or snow, a larger diameter gutter is a better choice for overall functionality over time.
