The Short Answer
A full roof replacement in Indianapolis typically runs between roughly $9,000 and $22,000 for an average single-family home, depending on square footage, roof complexity, decking condition and shingle selection — larger or steeper homes run higher. John Beal Roofing tears off to bare deck, inspects and replaces damaged decking at a per-sheet price quoted up front, corrects attic ventilation, and installs to Owens Corning Platinum Preferred standards with a lifetime workmanship warranty on qualifying work.

What Drives the Price of an Indianapolis Roof
Four things, roughly in order of impact. Square footage is the obvious one, measured in roofing squares of 100 square feet. Complexity is the one homeowners underestimate: a simple gable roof of a given size costs meaningfully less than the same area cut up with dormers, valleys, hips and skylights, because the labor and the waste both climb. Pitch matters too — anything steep enough to require additional safety equipment slows the crew down.
Decking condition is the variable nobody can price accurately before tear-off. That is why an honest estimate quotes a per-sheet allowance rather than pretending to know. On a 1950s Beech Grove house we expect some replacement; on a 2015 Westfield house we usually expect none.
Shingle selection is the last, and usually the smallest, real driver. The gap between a good architectural shingle and a premium designer line is real but modest relative to labor. Which is why we tell people plainly: a mid-grade architectural shingle installed correctly on a properly ventilated attic will outlast a premium shingle installed carelessly on a starved one. Spend on the installation.
Tear-Off Versus Layover
A layover — installing new shingles over the existing layer — is cheaper up front and worse in essentially every other respect. It hides the decking, so nobody knows what condition it is in. It adds significant weight to the framing. It traps heat, which shortens the life of the new shingles. And it makes the next replacement more expensive because two layers have to come off.
We tear off to bare deck. That is not an upsell position; it is that we cannot warrant work when we do not know what is underneath it. Once the deck is exposed we walk it, mark soft or damaged sheets, photograph them, and replace at the per-sheet price you already agreed to.
Ventilation: The Part Most Bids Skip
A roof is a system that includes the attic beneath it. If hot air cannot escape at the ridge and cool air cannot enter at the soffit, the attic superheats, the shingles cook from below, and a thirty-year shingle delivers eighteen. In winter the same imbalance drives ice damming, because heat escaping unevenly melts snow that refreezes at the cold eave.
The mistake we see constantly around Indianapolis is exhaust-heavy, intake-starved: plenty of ridge vent, and soffit intake blocked by insulation pushed into the eaves. The homeowner improved their attic insulation and unknowingly strangled the roof. We check intake during the inspection, and correcting the balance is part of doing a replacement right rather than an add-on line item we spring on you later.
What Happens on Installation Day
Crews typically arrive early and complete an average Indianapolis home in one day, with larger or more complex roofs running two. Before anything comes off, we protect landscaping and set up dumpster placement — on tight lots in places like Speedway or Beech Grove that staging matters as much as the roofing.
Tear-off, decking inspection and any replacement, then ice-and-water membrane at eaves and valleys, synthetic underlayment across the field, starter course, shingles installed to manufacturer nailing specification, then ridge cap and ventilation. Flashing is replaced rather than reused. Reusing old flashing to save a few dollars is one of the more common corners cut in this trade.
At the end, the crew runs magnets over the property for nails, cleans the gutters of debris from the job, and walks the roof with you or photographs the finished work. Then the paperwork: manufacturer warranty registration and your workmanship warranty.
The overwhelming majority of replacements we perform in central Indiana finish in asphalt shingle, and the details that decide how long that surface lasts — nailing zone, flashing, ventilation, what goes down before the first bundle — are laid out in full on our shingle roof installation page.
If your roof carries skylights, raise them with us before the tear-off rather than after. Setting a new unit into fresh decking with a new flashing kit while the roof is already open costs a fraction of opening the same area again in a few years, and our skylight repair and installation page walks through how that decision usually goes.
Frequently Asked Questions
How much does a new roof cost in Indianapolis?
Most single-family replacements land between roughly $9,000 and $22,000 depending on size, complexity, pitch, decking condition and shingle choice. The free inspection produces a written, itemized number for your specific house.
How long does a roof replacement take?
Most Indianapolis homes are completed in one day. Larger or more complex roofs, or jobs with significant decking replacement, run two.
How long should a new roof last here?
A quality architectural shingle installed correctly on a properly ventilated attic should give you 25 to 30 years in central Indiana. Poor ventilation is the most common reason roofs fall short of that.
Do I have to tear off the old roof?
We tear off to bare deck on every replacement. A layover hides the decking condition, adds weight, traps heat and shortens the new roof's life. We cannot warrant what we cannot see.
What if you find rotted decking?
We quote a per-sheet price up front, before the job starts. We photograph every sheet we replace so you can see exactly what was done and why.
What warranty comes with a new roof?
A lifetime workmanship warranty on qualifying work plus the manufacturer's material warranty. As an Owens Corning Platinum Preferred contractor we can also offer extended system warranties that non-certified contractors cannot.
