What you are actually paying for when a commercial roof needs work
Let me walk you through how this really breaks down. When someone calls us about a leak, the first question is not how much. It is what kind of roof do you have, how old is it, and where is the water showing up inside? Those three answers tell us about 80 percent of what we need to know before we even climb up there.
If you have a TPO or EPDM membrane that is under 15 years old, repair is usually the right call. We are talking about patching a seam, sealing a penetration around an HVAC curb, or replacing a section where something punctured it. You are not rebuilding the whole system. You are fixing what failed. If you want a sense of what a proper look at the roof involves, our commercial roof inspections page walks through exactly what we check and why.
Now if your roof is pushing 20 years, has multiple leak points, and the membrane feels brittle when you walk on it, that is a different conversation. You can keep patching, but you are basically renting time. At some point the math flips and replacement makes more sense than another round of commercial roof repair calls every spring.
What about metal roofs? Those tend to last longer but the repair work is different. Fastener backout, panel separations, and rust at flashings are the usual suspects. A retrofit over an existing failing roof is sometimes possible too, which can save you serious money versus a full tear off.
And here is something most folks do not think about. A big part of what you pay for is the prep work nobody sees. Setting up safe access on a flat roof with parapet walls. Protecting the rooftop units while we work around them. Hauling tear off debris down without damaging your landscaping or parking lot. On a busy property in Sheridan, sometimes we have to stage work in phases just so your tenants or customers can keep coming and going. None of that shows up as a line item that screams at you, but it is real labor and real time, and it is part of why a good crew costs more than the guy with a pickup truck and a roll of patch material.
Real cost ranges for Sheridan commercial roofs
You want numbers, so here are honest ranges based on what we see across Sheridan and Central Indiana. These are not quotes, they are ballparks to help you budget the conversation.
See how wide those ranges are? That is not us hedging. That is reality. A 10,000 square foot TPO replacement in Sheridan can land anywhere from $70,000 to $110,000 depending on whether the insulation underneath is salvageable, how many penetrations you have, and what shape the deck is in. If we open it up and find soaked insulation or rotted decking, that adds cost. We would rather warn you up front than surprise you on day three.
What else moves the number around? Insulation thickness for one. Energy codes have tightened over the years, so if your old roof had R-12 and code now wants R-25 or better, that is more material going down. Then there is membrane thickness. A 60 mil TPO costs less than 80 mil, but the thicker product gives you more puncture resistance and a longer manufacturer warranty. If you have foot traffic up there from HVAC techs every month, the thicker membrane usually pays for itself. Drains, scuppers, edge metal, walk pads, and curb flashings all add up too. A roof with 30 penetrations is not the same job as a roof with 5, even if the square footage matches.
How to decide between repair and replacement
Here is the simple test you can run yourself. Ask three questions. How old is the roof? How many leaks have you had in the last two years? And what is the leak costing you in interior damage, lost product, or downtime?
If the roof is under 15 years old and you have had one or two leaks, repair almost always wins. If it is over 18 years old with chronic leaks at multiple spots, you are probably looking at commercial roof replacement within the next year or two, so spending big on repairs now is just delaying the inevitable.
What about insurance? If a storm caused the damage, document everything before you touch it. Photos, dates, interior damage too. We work with adjusters all the time and we can help you put together what they need. Just do not let an active leak sit while you wait. Get a tarp or temporary dry in on it so you are not also dealing with mold and ruined inventory.
One more thing. Beware of anyone giving you a hard quote without walking the roof. That is a red flag. A real estimate comes after someone has actually looked at your seams, your flashings, your drains, and your deck. Anything else is a guess pretending to be a price.
When you do call Sheridan Commercial Roofing, here is what happens. We talk through the situation on the phone first and get a read on severity. If water is actively coming in, tarping and dry in get prioritized so the damage stops spreading. Then we schedule a proper inspection fast, walk the roof, and put together a written scope with photos so you can see exactly what we saw. No pressure, no scare tactics, just the facts about your roof in Sheridan and what your real options look like. That way you can make the call with your eyes open, whether that is a small repair this month or planning a full replacement into next year's budget.
