Gutter replacement pricing runs by linear foot plus accessories. 2026 installed rates: seamless aluminum $8-$15 per linear foot, galvanized steel $10-$18, copper $25-$45, vinyl $5-$9 (not recommended — 5-8 year lifespan). Downspouts add $8-$15 per linear foot. Gutter guards run $7-$15 per linear foot installed. Two-story installation adds 25-40% over single-story.
5-inch vs 6-inch K-style — when size matters
5-inch K-style handles most residential roofs under 1,800 sq ft with moderate roof pitch. 6-inch K-style handles larger roofs, steep pitches that concentrate water flow, and high-rain climates. The upcharge for 6-inch is only 20-25% but the added capacity prevents overflow during heavy rain events. For any new construction or full replacement, 6-inch is worth the small premium.
Guards — which types actually work
Reverse-curve (Leaf Guard, LeafFilter) work well in pine needle and small debris environments but cost $20-$40 per linear foot installed — often more than the gutters themselves. Micro-mesh stainless steel ($15-$25/lf) is the current gold standard for any property. Foam inserts ($5-$10/lf) are cheap but trap debris and decompose. Screens and brush inserts work for leaves but fail on shingle grit and pine needles. For heavily-treed properties, micro-mesh pays back within 3-5 years in ladder time saved.
Downspout extensions — the detail most people miss
Standard gutter installs terminate downspouts at ground level, dumping water next to the foundation. This is the #1 cause of basement flooding and foundation settlement. Proper installation includes rigid downspout extensions minimum 6 feet from foundation, connected to dedicated drain lines that daylight to lower ground. Budget $150-$400 per downspout for proper extension; $500-$1,500 if underground drainage to a dry well or rain garden is added.
