What is the 25% rule for roofing?

The 25% rule is a code guideline that can require a full replacement when a large share of the roof is damaged or repaired within a set period. We recommend full tear-offs in nearly all cases so we can inspect the deck, replace flashing per code, and keep one uniform warranty.

How much does it cost to replace a roof on a house?

Cost is based on roof area in squares, not the home's square footage, because pitch and complexity change the area. Our free drone inspection gives accurate measurements and flags hidden damage before we price anything.

Can I replace just part of my roof?

Partial replacements are possible for isolated storm damage on one slope, but matching color and texture on an aged roof is difficult. When the roof is near the end of its life, a full replacement avoids mismatched sections and keeps warranty coverage uniform.

What happens if it rains during my roof replacement?

We watch the forecast and stage work to limit exposure, and tarps go on right away if rain arrives unexpectedly. Modern synthetic and peel-and-stick underlayments also provide temporary waterproofing, so a brief delay rarely causes interior damage.

Do I need to replace my gutters when I replace my roof?

Gutters do not always need replacing during a roof project. The replacement is still an ideal time to swap them if they are damaged, sagging, or near the end of their lifespan.

AT A GLANCE

What a Lee's Summit Roof Replacement Involves

A full replacement means tearing off the old roof down to the deck, then installing new underlayment, flashing, drip edge, and shingles to code. Missouri's freeze-thaw cycles and hail exposure age roofs faster than many homeowners expect.

Replacing before the 15-year insurance inspection threshold helps avoid coverage gaps, since older roofs may be limited to actual cash value payouts. Waiting for a leak often means replacing on someone else's timeline.

THE TIMELINE

How Long a Lee's Summit 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

Water trapped in shingle cracks freezes and widens them, and fasteners loosen as the deck expands and contracts dozens of times a year. Many older Lee's Summit roofs also lack kick-out flashing, which lets water rot the wall without visible clues.

Daylight through the attic deck
Sagging deck or rooflines

INSURANCE

Does Insurance Cover Roof Replacement in Lee's Summit?

Storm damage from hail or wind is typically covered if the roof is under the carrier's age threshold, while wear-and-tear replacement is not. Most policies also require damage to be reported within a set window after the storm.

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

Asphalt shingles cost less upfront and are the default for most homes, while architectural shingles hold fasteners better in wind and hail. Metal costs more initially but can outlast two or three shingle roofs.

THE FULL SYSTEM

Why Flashing and Underlayment Matter as Much as Shingles

A roof replacement is a system, not just shingles. Cutting corners on any one component, like reusing old flashing, compromises the entire assembly.

We install asphalt shingle and low-slope modified bitumen roofing, with every tear-off getting new flashing and underlayment built to code and manufacturer specs.

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.
