Gutters & Guards Shopping Guide (In-Depth)

---

Surface rust and paint blistering indicate the protective coating has failed. Pinhole leaks quickly expand and will stain fascia and siding. If corrosion is widespread, or if sections are thin or pitted, replacement is more effective than patching.

Clean and dry joints before applying gutter sealant; replace worn hangers and adjust pitch to maintain 1/16–1/8 inch per foot toward downspouts. Re-hang sections that hold water (sagging) and re-seal miters, outlets, and end caps. After adjustments, run a hose test to confirm continuous flow.

Gutters must fasten to sound framing. Replace rotted fascia, sub-fascia, and soffit so fasteners hold securely. Prime cuts and use corrosion-resistant fasteners. Consider adding a drip edge and proper flashing to protect new wood.

Larger profiles increase capacity and reduce overflow during cloudbursts. Use additional downspouts on long runs and at inside valleys. Confirm underground drainage can handle the added flow to avoid backups.

Formed on-site from a continuous coil, seamless gutters minimize miters and splices. They require accurate measurements and proper hanger spacing for strength. While sectionals can work, expect more joint maintenance over time.

Aluminum: light, corrosion-resistant, widely used. Vinyl: economical, but can become brittle in UV/cold. Steel: strong, heavy; needs quality coatings. Copper: premium aesthetics; patinas naturally. Zinc: durable with self-healing patina. Wood: traditional look; high maintenance.

Service life depends on climate, salt/industrial exposure, roof run-off chemistry, and maintenance. Quality hangers, compatible fasteners, and routine cleaning extend longevity regardless of material.

Gutters and downspouts don’t have to match trim. A darker contrasting color can frame the roofline and hide stains. Coordinate with fascia/soffit colors and downspout routing for a cohesive look.

Flush or camera-inspect yard drains and corrugated lines. Add cleanouts and leaf traps where possible. Backed-up drains can cause hidden foundation or landscape damage.

Guards reduce debris, but no system is maintenance-free. Micro-mesh handles fine debris; solid covers shed leaves and needles but need proper pitch. Match the guard to your tree types and roofline; ensure compatibility with your roof warranty.

Fasten gutters to fascia, not through the roof, unless using manufacturer-approved methods. Protect the drip edge and underlayment, and avoid prying shingles. Seal penetrations and keep guard systems from lifting shingle edges.
