5-inch vs. 6-inch gutters
Understand the practical questions behind sizing and roof drainage.
What influences the conversation
Common residential sizing discussions consider drainage area, roof pitch, valleys, rainfall intensity and the capacity of downspouts. A professional can connect those factors to the home rather than choosing by label alone.
Questions to ask
Ask what roof areas drain into each run, how overflow history is being handled and whether the proposed size works with the downspouts and roofline. Aesthetic preferences and maintenance access can matter too.
