When to replace

Signs you need asphalt shingle roof replacement in Kahului

  • The roof is 20+ years old (near or past asphalt's service life)
  • Shingles are cracked, curling, buckling, or missing after storms
  • Granules collecting in the gutters or bald, shiny spots on shingles
  • Water stains on ceilings or in the attic, or daylight through the roof boards
  • A sagging roofline or soft, spongy deck underfoot
  • Moss or dark algae streaks holding moisture against the shingles
  • Repeated leaks even after patch repairs
Decision

Repair or replace in Kahului?

Rule of thumb: if storm or wear damage covers more than ~30% of the roof, or the roof is past 75% of its rated life, full replacement usually beats repeated repairs.

Repair if…

  • Damage is isolated to a few shingles or one slope
  • The roof is under ~15 years old and the deck is sound
  • A single flashing or vent boot is the source of the leak

Replace if…

  • The roof is 20+ years old and leaking in multiple spots
  • There's widespread granule loss, curling, or storm damage
  • The deck is sagging or has rot — the structure, not just the surface, is failing
  • There are already two layers of shingles (most codes cap it at two)

Reading your quotes

Why asphalt shingle roof replacement quotes vary — and how to compare them fairly

A wide spread between bids rarely means someone is overcharging; it usually means they priced different work. Below is what moves the number and how to line the quotes up.

Why a quote looks high (or low)

  • One bid is a full tear-off; another lays new shingles over the old roof — cheaper now, costlier later.
  • A storm-chaser's lowball often skips flashing, ice-and-water shield or a real warranty.
  • Deck repair, underlayment grade and ventilation may or may not be in the price.

Get an apples-to-apples bid

  • Ask how deck/sheathing repairs are priced if rot is found.
  • Confirm underlayment, ice-and-water shield, flashing and ventilation are included.
  • Specify tear-off vs. overlay so all bids match.
  • Compare the workmanship warranty, not just the material warranty.

Editors' roundtable

Where does a smart roofing budget go in 2026?

Tear-off vs. overlay, shingle tier and what's hidden under the deck decide the real number. Our editors on the trade-offs.

The value case

Architectural shingles hit the sweet spot — far more durable than 3-tab for a modest premium, and far cheaper than metal or tile. For most homes they're the right default.

The risk case

Nail down the per-sheet decking rate in writing before anyone climbs up. Soft or rotted plywood is the most common mid-job discovery, and without an agreed number the crew names the price after they've already found the damage — turning a cheap quote into an open tab.

The do-it-right case

A full tear-off lets the crew replace underlayment, flashing and ventilation while the deck is exposed — the layers that actually keep water out. Covering old shingles with new ones costs less on install day, but the trapped heat shortens shingle life, and many manufacturers won't honor a warranty on an overlay.

Our take

Insist on tear-off over overlay, get the deck-repair rate in writing before work starts, and lean toward architectural shingles. Skipping any of the three tends to cost more later than it saves now.
