Five-inch handles most homes. Six-inch is worth it where a large roof area drains into a single run, where the pitch is steep enough to accelerate runoff, or where your current gutters overflow in heavy rain. We’ll tell you which your roof actually needs.

It comes down to the total length of the run, the number of downspouts, how many storeys, whether any fascia needs repairing, and whether you want guards. We measure and give you a written price.

Under mature trees, usually yes — they save you a couple of cleanings a year and reduce the risk of a blocked gutter overflowing. On a house with no trees nearby, they’re often an expense without much return. We’ll give you an honest opinion for your house.

No. Ice dams are caused by heat escaping into the attic and melting the snowpack from below. Gutters don’t cause them, though a gutter packed with ice makes them worse. The real fix is attic air sealing, insulation and ventilation — see our roof repair page.

Frequently, and it makes sense to. The crew is already on site, the fascia is accessible, and the roof edge, drip edge and gutter all get finished as one system.
