Gutters Sized For Your Actual Roof

Aluminum, Copper, And Steel — When Each One Wins

We install three materials and skip the fourth. Seamless aluminum is what goes on most NJ houses — .032 gauge minimum, 30+ year lifespan, baked enamel finish in roughly 30 colors. It's the right call for the vast majority of residential work and we run it from our own on-site brake. Copper is for historic restorations, high-end architecture, and anyone who wants the natural patina aesthetic — runs three to four times the cost of aluminum and lasts 80+ years. Galvanized steel is for industrial applications and certain commercial work where impact resistance matters more than weight.

What we don't install: vinyl. It's brittle in NJ winters, sags under wet leaf load, and is the cheapest answer to a question that doesn't deserve a cheap answer. If you already have vinyl gutters and they're failing, we can repair what's repairable, but the long-term answer is replacement.

Why 5-Inch Versus 6-Inch Actually Matters

Five-inch K-style gutter is the residential default — fine on most NJ houses, plenty of capacity for an average roof area in an average storm. Six-inch is the right call once you're past 1,000 square feet of contributing roof area per downspout, on steep pitches that accelerate water velocity, or in storm-prone microclimates. The math is straightforward: a five-inch K-style holds roughly 1.2 gallons per linear foot, a six-inch holds about 2.0 — that's a 65% capacity increase for a 20% upcharge. Skipping the six-inch upgrade on a house that needs it is the most common cause of gutter overflow we see. Downspout count matters as much as gutter size — one three-by-four-inch downspout per 30-40 feet of gutter run, depending on pitch and roof area. Long single-downspout runs always overflow somewhere in the middle of the gutter during real rain. We do the calculation as part of every estimate and write the spec on the quote so there's no ambiguity.

Hangers, Pitch, And Outlets — Where Most Installs Fail

Hidden hangers screwed into rafter tails — never spike-and-ferrule through fascia, never nails. Spikes loosen as fascia expands and contracts; once a single spike pulls, the gutter starts pulling everything around it down with it. Hidden hangers anchored into structural framing don't budge. Pitch runs a quarter inch per ten feet toward the downspout — sounds trivial, isn't. Flat-pitched gutters hold standing water, which freezes, which cracks the gutter, which becomes the leak you discover in March. Outlets get cut and sealed, not punched and prayed-over — punched outlets tear the gutter wall and leak from day one.

We also install drip edge and proper flashing details at the gutter line where most installers leave a gap. Water that gets behind the gutter is what rots fascia from the back side.

What's Covered, And For How Long

Aluminum gutter material carries a manufacturer warranty against finish degradation — 20 years on standard baked enamel, 30+ on premium coatings. That covers the paint job. The aluminum itself doesn't really fail in residential use. Our installation warranty is a minimum of 1 year on every job, written and signed, covering hanger work, sealant joints, downspout connections, outlet integrity, and pitch performance. If a gutter pulls away from the house in year one because we didn't anchor it properly, that's on us — we come back, fix it, no charge, no argument. If you sell the house, the workmanship warranty transfers to the buyer. If you're considering gutter guards as an add-on, we install those too, and the same warranty terms apply.
