A full roof replacement is a multi-day job, not a one-day miracle, and the crew’s process matters more than the number on the quote. That is the honest answer for anyone who just bought an older Leawood house and got handed a reroof they have never once watched happen from the driveway. The roofing companies leawood ks homeowners actually keep calling back are the ones who treat tear-off, decking, and cleanup as three separate jobs instead of one blurry line item on a sheet of paper. Buy on the sticker alone and you learn the difference the hard way.

A Full Reroof Begins With A Tear Off
Everything starts with removing what is already up there. A crew strips the old shingles, the felt, and the flashing down to bare wood, and that first day is loud, dusty, and quicker than most owners expect once the shovels get moving. The dumpster tells the real story here, because two layers of old asphalt on a 1970s two-story fill a container faster than anyone plans for on paper. Prices for the new material have not helped either. The Illinois Roofing Institute reported in June 2026 that Owens Corning’s Q1 2026 roofing sales dropped 14% to $960 million even as material costs kept climbing, a squeeze that lands straight on your written estimate. So the tear-off is not just demolition for its own sake. It is the moment the crew finally sees what they are truly working with, and a careful outfit slows down right here.
Decking Problems Decide The Real Timeline
Under those old shingles sits the decking, and that is exactly where a clean-looking quote goes sideways. On a 1970s house you often find plank decking or thin plywood that has quietly soaked up 40 years of small leaks nobody ever chased down. Budget three days for a straightforward reroof. Honestly, make it five once soft decking turns up, because every rotted sheet has to come off and get swapped before a single new shingle goes down. The case we see most often is a homeowner who priced the whole job on shingles alone and never accounted for the tired plywood hiding underneath. A crew worth hiring counts and photographs each bad sheet, so the change order reads like a receipt rather than a mystery you have to argue about later.
The Week By Week Rhythm Of An Install
Here is how a full reroof actually unfolds on the ground. Day one is tear-off and decking repair, the messiest stretch by a wide margin. Day two the crew dries the roof in with underlayment and sets the drip edge, the valleys, and the flashing, the quiet unglamorous work that quietly decides whether this roof leaks in five winters or twenty. Day three brings the shingles, the ridge vents, and the fussy details around the chimney and the pipe boots. By the first week most Leawood reroofs are buttoned up, weather permitting, though a big two-story with a steep pitch can push into a short second morning of detail work. You can rough out your own roof size before any of this even starts by pulling the house up in Google Earth and measuring the footprint, which hands you a sane number to sanity-check a bid against. None of it is magic. It is sequence, plain and simple, and skipping a step to shave the price always shows up later.
A Named Underlayment Choice Changes Longevity
The underlayment layer is where longevity is really won or lost, and it turns invisible the second the shingles cover it. This is the ice-and-water shield, a self-sealing membrane run along the eaves and up through the valleys where meltwater tends to back up under pressure. It earns its keep in a Kansas winter. Ice dams do not form from cold alone, and the University of Minnesota Extension explains that they build when the upper roof surface climbs above 32 degrees F while the lower edge near the gutter stays below 32 degrees F, so the melt runs down and refreezes at the cold eave. That is attic heat loss doing the damage, not the brand printed on the shingle wrapper. A crew that runs proper membrane at the eaves is protecting you from the exact leak you would otherwise blame on the roof itself three winters from now.
A Clean Site Signals A Real Roofer
The last day tells you plainly who you actually hired. A real crew runs a magnetic sweep across the whole yard for stray nails, tarps the landscaping while the work is happening, and hauls that loaded dumpster off before dark. Cut-rate outfits skip the sweep, and you keep finding roofing nails in the driveway and the flower beds for months afterward. That final cleanup is not a courtesy thrown in at the end. It is the same discipline that put the flashing in right and laid the membrane down straight, only now it is the part you can finally see. When you compare roofing companies leawood ks homeowners recommend to their neighbors, weigh the whole process from the first tear-off shovel to the last nail swept out of the grass, because that sequence is what you are genuinely buying, not the shingle on a sample board. Pick the crew that treats your yard like the job is not done until it is truly clean.
