Roof replacement in Overland Park

When it's time

Overland Park's housing tells you most of what you need to know. The subdivisions between I-435 and 135th Street went up in the 1980s and 90s; the Blue Valley area south of 135th filled in from the mid-1990s through the 2000s. A large share of those homes got a new roof after one of the big hail years, and those roofs are now well into the 18–25 years architectural shingles typically get here, less where hail has shortened it. The signs:

• Granules piling in the gutters and bare black patches on the south and west slopes
• Shingle edges curling or cupping, which is where wind gets its grip
• Two or more repairs in the last couple of years in different places
• A roof already on its second layer (you can see the stacked edge at the drip edge)
• Decking that feels spongy underfoot
• Hail bruises — soft dark spots where the granules were knocked loose — on more than one slope

If you're seeing two of those, read our post on signs an Overland Park roof is near the end, then request an estimate. A good roofer will tell you if it has a few years left, and whether hail damage means you should call your insurer before paying for it yourself.

What a replacement built for Johnson County should include

In residential roofing, Overland Park roofs have two jobs the rest of the country worries about less: shrugging off hail, and staying sealed through dozens of freeze-thaw swings a winter. Whether it's a general roof replacement in Overland Park, KS or a complex Blue Valley roof, the quote should include:

• Full tear-off to the deck. A second layer hides rot, traps moisture, and makes hail damage hard to assess on the next claim.
• Decking check. Any soft or delaminated OSB replaced at $90–$150 per sheet. The 1990s subdivisions used 7/16 OSB, and where a gutter overflowed for years it is often gone at the eave.
• Ice-and-water membrane at the eaves, in every valley, and around every penetration. What the code requires depends on your city — check with its building department; many roofers run it further because February proves the point every year.
• Synthetic underlayment over the rest of the deck, not felt.
• New drip edge, new pipe boots, new flashing. Don't accept reused 20-year-old flashing under a new roof.
• Architectural shingles — Class 4 impact-resistant if you choose them, for the reasons on the Class 4 page — nailed six per shingle to the manufacturer's high-wind pattern.
• Ridge ventilation cut in, with soffit intake checked. On roof ventilation, Overland Park's older ranches are often the worst, and a new roof over a 140°F attic wears out early.
• A permit, if your city requires one. Whether a re-roof needs a permit depends on your city — check with the City of Overland Park's building department (or Leawood's, Olathe's, Lenexa's), and make sure the permit is on the quote.

What it costs

Architectural shingles installed run $450–$800 per square in Johnson County, and most homes land between $9,000 and $22,000. That puts a simple ranch at $8,500–$14,000, a typical two-story at $12,000–$20,000, and a large Blue Valley home with a cut-up 35–40 square roof at $17,000–$22,000 or more. What moves the number: pitch, the number of valleys and dormers, a second layer to remove, decking repairs, and the shingle grade. Metal roofing? Overland Park installs run two to three times those figures. The pricing page breaks this down by house size and material, and our post on roof replacement cost in Overland Park shows real line items.

A roof over the old one is sometimes allowed, but most roofers here tear off; whether a layover is permitted depends on your city's code and the roof. A complete tear-off is the only way to see the deck.

Paying for it

Many homeowners use a home equity line, a home improvement loan or savings; compare the rate and fees before you sign anything at the kitchen table. If a claim is paying for most of the roof, many people only finance the deductible and upgrades.

Replacement after hail

A lot of replacements here are insurance-paid. The insurer's adjuster decides what the policy pays, and your deductible is yours to pay — a roofer who offers to cover, waive or rebate it is a red flag. The hail damage page walks through how a claim works.

Comparing replacement quotes

Two written quotes are only comparable when they describe the same roof. Before you look at the totals, check that each one names:

• The same shingle product, by line name, not just the brand
• A per-sheet decking price and a rough count of sheets, not "as needed"
• Where the ice-and-water membrane goes: eaves only, or eaves, valleys and every penetration
• Whether a ridge vent is being cut in and the soffits opened up
• New step and counter-flashing, rather than "reuse where possible"
• The permit, the dumpster and the cleanup
• The workmanship term in years, and who you call to use it

If one quote is thousands lower, it is usually missing two or three of these lines. Ask the roofer to add them and re-price before you decide.

Mistakes that cost homeowners later

• Choosing on the total alone. The cheapest number often buys felt, reused flashing and no ventilation.
• Ordering a color before checking the HOA. Several Johnson County associations keep an approved list, and a rejected color is an expensive problem once it's nailed down.
• Signing a claim job before the insurer has decided. Wait for the adjuster's decision, then compare it with the written estimate.
• Ignoring the attic. A new roof over a hot, damp attic ages faster than the one it replaced.
• Hanging old gutters back on soft fascia. If the board behind the gutter is rotten, have it replaced while the edge is open.

After the crew leaves

Walk the yard and driveway yourself, then look in the attic on a sunny day for daylight or nails that missed the rafters. Keep one folder with the final invoice, the shingle product name, the permit sign-off if your city issued one, the workmanship terms and the manufacturer's warranty paperwork. The next buyer, inspector or adjuster will ask for exactly those pages.

How the day goes

A typical replacement on a new roof in Overland Park is one to two days. Tear-off takes the morning on a typical two-story, and the deck should be inspected and underlayment down before anything is left open overnight. Ask the crew to run magnets over the yard and driveway for nails before they leave, move the cars out of the garage, and take anything fragile off the walls — the hammering shakes the whole house.
