Frequently Asked Questions
Why do my gutters overflow during heavy rain?
Gutters overflow when they can't handle the volume of water. In Houston, this is often because 5-inch gutters are too small for large roof areas, or because clogs restrict water flow.
Should I upgrade to larger gutters?
If your gutters overflow during moderate rain, upgrading from 5-inch to 6-inch gutters can increase water handling capacity by about 40%. This is especially recommended for Houston homes with large or steep roofs.
