What is the average cost to have a new roof?

HomeAdvisor's 2024 data puts the typical national cost at $6,135 to $13,987, averaging about $10,061. A simple ranch lands toward the low end, while a steep two-story with multiple valleys and premium shingles runs higher.

How soon after a hailstorm should I have my Grandview roof inspected?

Get an inspection as soon as possible, because bruised shingles lose granules over weeks and months before they leak. Early drone documentation strengthens your claim and keeps the carrier from blaming later leaks on wear.

Can I replace just the damaged section of my roof?

You can if the damage is isolated and the rest of the roof has years of life left, but new shingles rarely match older ones and a poor tie-in can void the warranty. If the other sections are already 15 or more years old, a full replacement usually makes more sense.

Do I need to be home during the roof replacement?

You do not need to be home during the work, but plan to be available for a walkthrough before we start and a final inspection at the end. The crew needs access to exterior outlets and the noise is significant, so pets and young children may be happier away for the day.

Will you replace damaged decking?

After tear-off we inspect the deck and replace any soft or rotted sheathing. Decking work is documented with photos and explained before we proceed.

What a Grandview Roof Replacement Involves

Grandview quotes vary by roof size, pitch, material, and the number of layers being removed. Every job starts by tearing off to the deck and replacing any damaged sheathing before the new system goes on.

Kansas City's freeze-thaw cycling and recent severe wind events speed up roof wear. Replacing before the 15-year insurance inspection threshold is usually smarter than waiting for a carrier-mandated upgrade.

THE TIMELINE

How Long a Grandview Roof Replacement Takes

Most homes finish in one to three days. Rain or high wind can pause work to protect the open deck, and valleys, chimneys, skylights, and steep pitch add time.

Phase 1 · ½ – 1 day
Tear-Off & Deck Inspection
Old shingles, underlayment, and damaged flashing come off down to the plywood or OSB deck. Soft, rotted, or sagging sections are replaced before anything new goes down.
Phase 2 · ½ day
Underlayment & Flashing
Synthetic or peel-and-stick underlayment, drip edge around the perimeter, and new flashing at every valley, chimney, vent, and roof-to-wall joint, per code.
Phase 3 · 1 – 2 days
Shingles & Cleanup
Shingles go on from the eaves up to the ridge, hips and ridge get capped, and all debris is hauled off with a magnetic sweep of the yard and drive.

WARNING SIGNS

Signs You Need a New Roof

Hail bruises knock granules loose and leave the asphalt mat exposed to UV, aging the roof even when damage is not visible from the ground. Freeze-thaw cycles then widen cracks and loosen fasteners each season.

Curling, cracked, or missing shingles
Granule loss in the gutters
Daylight through the attic deck
Sagging deck or rooflines
Leaks or ceiling water stains

INSURANCE

Does Insurance Cover Roof Replacement in Grandview?

Coverage applies when damage comes from a covered peril like hail, wind, or fire. Roofs that have outlived their rated lifespan without an inspection waiver are usually not covered.

Usually Covered

Hail damage
Wind damage
Fire or a falling tree
Roofs under the carrier's age threshold

Usually Not Covered

Normal wear and tear
Deferred maintenance
Roofs past their rated lifespan
Older roofs may get actual cash value only

15–20 yrs

Many insurers now require an inspection to renew coverage on roofs this old, and some will not renew roofs over 20 years unless they pass. Replacing before that threshold keeps full replacement cost coverage. We document storm damage with drone photos, work directly with adjusters, and offer financing when insurance does not cover the full cost.

MATERIALS

How Long Each Roof Lasts

A premium architectural shingle costs less upfront but needs replacing in two to three decades, while standing-seam metal can outlast two or three shingle roofs. We walk you through warranty coverage and long-term cost per year.

THE FULL SYSTEM

Why Full Tear-Off and Code-Compliant Flashing Matter

A full tear-off exposes the deck so we can inspect for rot, replace damaged sheathing, and install ice-and-water shield where water concentrates. Freeze-thaw movement opens flashing seams and cracks sealant, so reusing old metal is a shortcut we never take.

Most shingle manufacturers void coverage if flashing does not meet their specifications. Replacing every flashing protects both the home's structure and the roof warranty.

IRC R908.5 & R908.6: rusted, damaged, or deteriorated flashings must be replaced during reroofing and rebuilt to the manufacturer's instructions.

Ice-and-Water Shield

At eaves and valleys, where freeze-thaw water concentrates.

Synthetic Underlayment

Temporary waterproofing and a second barrier under every shingle.

Drip Edge

Guides runoff into the gutters and protects the deck edge.

Step & Valley Flashing

Seals joints and penetrations shingles alone cannot seal.

Kick-Out Flashing

Keeps runoff out of the wall where the roof meets siding.

Balanced Ventilation

Intake and exhaust sized to the attic so shingles are not cooked from below.
