Schedule Your Free Roof Inspection

A commercial roof inspection in St. John starts on the deck, not from the ground. Our crew walks the membrane looking at seams, laps, and terminations, checks flashing at parapets and curbs, inspects penetration boots and pitch pans, and looks hard at any ponding areas or spots where the roof has lost positive slope. We document everything with photos, note storm damage separately from age related wear, and give you a written summary you can hand to ownership or an adjuster. Most St. John commercial buildings we look at have some mix of membrane fatigue and flashing issues, and catching those early is what keeps a small repair from turning into a full replacement conversation two years down the line.

I agree to be contacted by St. John Commercial Roofing regarding my inquiry.

Roof warranties across St. John cover less than owners assume and demand more than installers mention. Annual inspection requirements, documented maintenance, and manufacturer approved repairs are conditions, not suggestions. The Lake County owner who discovers the warranty lapsed for want of a paper trail learns that the cheapest inspection is the one that keeps coverage alive.

Safety compliance rides on every St. John Commercial Roofing job: fall protection planned before mobilization, perimeter warning systems on low slope work, and documentation St. John building owners can hand their insurer. Commercial roofing is dangerous work done above valuable operations, and Lake County owners should never have to wonder whether the crew on their roof is covered.

St. John Commercial Roofing maintenance agreements put St. John buildings on a two visit calendar: spring walk after the freeze, fall walk before it, drains cleared and details resealed both times. The visits cost less than the leaks they prevent, and the documentation keeps warranties enforceable. Call (317) 342-7736 to add your Lake County building to the schedule.

About Us

Local Expertise, Real Results

Every St. John scope we write is one we would defend line by line in a budget meeting.

Budget season is when roof plans live or die. St. John Commercial Roofing writes St. John proposals that separate must-do from can-wait with real numbers on each, so the roof line survives the capital meeting intact.

St. John Commercial Roofing serves St. John and the surrounding Lake County commercial market, including Schererville, Dyer, Crown Point, and Cedar Lake. Founded in 2018 by Aaron Christy, who has been featured on FOX59, WISH TV, and RTV6, the company has spent years focused on low slope membrane work, repair, and full replacements on commercial buildings. Our crews are local to the region, licensed and insured in Indiana under RC21100059, and used to the kind of retail and office stock that dominates St. John. When a property manager calls, they get people who understand the buildings, the weather, and how Lake County commercial roofs actually fail.

The way we work in St. John is straightforward. Every project starts with a thorough walk of the roof, photos of the seams, flashing, penetrations, and edge metal, and an honest conversation about what we found. From there you get a written estimate with a clear scope, no vague line items, and no pressure. On the work itself we keep the site clean, protect the tenants and the parking areas, and stand behind the workmanship. No invented certifications, no brochure talk, just commercial roofing done the way it should be done.

Our Promise

We make three commitments to every St. John property manager who calls us. First, a free on site inspection of your commercial roof before any work is discussed, with photos of what we find. Second, an honest written estimate with a clear scope and transparent line items later. Third, clean workmanship on the roof, a final walkthrough when we finish, and a workmanship warranty on what we install. That is the deal, and it does not change based on the size of the building.

Why St. John Chooses Us

How We Earn Repeat St. John Work

Serving St. John and Lake County with quality materials, thorough inspections, and transparent pricing.

Storm And Hail Response

Northwest Indiana had significant tornado and straight line wind events in 2026, and commercial roofs took real damage across the region. We prioritize storm calls, get on the roof, and document wind lifted seams, displaced edge metal, and hail bruising on membrane. You get photos and a written scope you can send straight to your carrier.

St. John Commercial Experience

We work on the strip centers, inline retail, and office condos that make up most of St. John's commercial footprint along Wicker Avenue and Calumet Avenue. That means we know the TPO and EPDM systems installed here from 2000 forward, and we know the aging modified bitumen on the older retail cores. You get a contractor who has seen your building type many times before.

Full-Scope Commercial Roofing

From the first inspection to the final walkthrough, one company handles the whole job. Inspections, repairs, emergency work, full replacements, and metal roofing installs all sit under St. John Commercial Roofing. For a property manager juggling multiple buildings, that means one point of contact and one consistent standard of work across St. John properties.

Claim Documentation Done Right

Insurance claims live or die on documentation. We photograph damage with context, note the date and cause when it is clear, and separate storm damage from wear so your carrier can process the claim cleanly. You get a report built to be handed to an adjuster, not a napkin sketch.

Our Process

How We Scope a St. John Commercial Roof

The first step in St. John is the inspection itself. We schedule the visit, get on the roof, and walk the entire membrane looking at seams, flashings, drains, penetrations, and edge conditions. We photograph problem areas, note anything that looks storm related versus age related, and check for ponding history. Before we talk price or scope, you get a clear picture of what the roof is actually doing. That grounds the whole conversation in what the building needs, not what a template says it needs.

Once the inspection is done, you get a written estimate with a defined scope, materials, and pricing. If there is a storm damage claim in play, we hand you the photo documentation and the written findings in a format that works for your insurance carrier and their adjuster. works with your insurance carrier and we do not name drop policies we cannot see. What we do is give a St. John property manager the paperwork and the roof access needed so the adjuster can do their job accurately.

The work itself gets scheduled around your tenants and your operating hours where we can. Crews stage materials cleanly, protect the walkways and parking, and keep the site tidy through the job. When the commercial roofing work is complete, we do a final walkthrough with you, review what was installed, and confirm the roof is left in the condition promised in the scope. Cleanup happens before we leave, not the next week. That is how we close out every St. John project.

Free Inspection With Photos

Every project starts with a no cost inspection of your commercial roof. We photograph seams, flashing, penetrations, and any storm or age damage, then walk you through what we found. No obligation to move forward.

Honest Written Estimate

You get a written estimate with a defined scope, clear materials, and line items you can read. If something is optional versus necessary, we say so. No mystery charges show up later in St. John.

Insurance Documentation

When storm damage is involved, we build the photo report and written findings your carrier and adjuster need. We work alongside your insurance carrier, not around them, and we never claim to bill them directly.

Clean Work, Final Walkthrough

Crews protect the property, stage materials safely, and clean up as they go. When the job is done we walk the roof with you, review the scope, and confirm the workmanship warranty on what we installed.

Common Causes

What we see most often on St. John commercial roofs

St. John property managers typically call us about these scenarios.

Deferred Maintenance That Compounds

Nothing on a low slope roof fails all at once. A lap opens, the insulation under it takes water, wet board loses compressive strength, the membrane above it moves more, and the next lap opens. St. John Commercial Roofing writes a condition report a facility director can hand to finance, with what has to happen this year and what can honestly wait.

Ballast and Coatings at the End of Their Run

Stone ballast hides everything under it, so a split sheet can sit open a long time before anybody knows. Coating systems have their own clock, since the film thins under UV and foot traffic. St. John Commercial Roofing tells you which one you have and whether a restoration coating even applies here, because coatings go over a roof that is sound and dry, and wet insulation has to come out first.

Hail Bruising on a Single Ply Roof

On single ply, hail fractures the reinforcing scrim under the surface without leaving an obvious hole, and the split shows up a season or two later. Whether there is a cover board under the membrane changes how well the roof took the hit. St. John Commercial Roofing documents impacts area by area with photographs and core cuts so a St. John building owner has a written record while the storm date is still recent.

Seams Letting Go on a Taped EPDM Roof

EPDM is a thermoset rubber, so its laps are taped or adhered rather than heat welded the way TPO and PVC are. The adhesive is what ages, and it usually gives up first at T joints where three plies stack on top of each other. A lap rebuilt while it is still just a lap is a maintenance line item. The same lap found two years later is an insulation replacement.

Punctures Along the Path to the Units

Map where the punctures are and they line up between the roof hatch and whatever equipment gets serviced. A self tapping screw dropped by a tech and then stepped on goes through a membrane without anyone noticing, and it does not leak where it went in. Walkway pads on the route people actually walk, plus a log of who went up and when, costs less than the third repair on the same area.

Wet Insulation Spreading Under the Membrane

The wet area under a low slope roof is almost always larger than the ceiling stain, because water gets past the membrane and travels sideways through the insulation until something stops it. An infrared scan does not see water. It sees heat, and wet board holds warmth longer after sunset, so it lights up at night. That tells St. John Commercial Roofing where to look, and a core cut tells you whether it is wet.

Common Questions

If You Are Wondering About Your St. John Roof

Straight answers to the questions St. John property managers ask most.

Typically, we schedule St. John inspections promptly and give priority to active storm damage and leaks. When a building is actively leaking or a storm just moved through Lake County, those calls jump the line so you are not sitting with tarps for days. For planned inspections and non urgent work, we set a time that works around your tenants and operating hours. Call in, describe what is going on, and we will get you on the schedule. Free inspection, no obligation.
It depends on the system, the size of the roof, and the scope. Most commercial repairs in St. John run in the hundreds to low thousands, larger sectional work and flashing rebuilds move into the mid four figures, and full replacements on multi tenant retail or office buildings are typically priced per square with pricing driven by the membrane type, insulation, and deck condition. We do not throw out numbers before we see the roof. The free inspection sets the real number in a written estimate.
It depends on your policy and what caused the damage. Sudden storm damage, wind lifted membrane, hail bruising, and displaced flashings are typically the kind of thing your insurance carrier will consider, while age related wear and deferred maintenance usually are not covered. You will still be responsible for your deductible, and the carrier makes the final call. We document the damage with photos and a written report so your adjuster has what they need. Call us out and we will help you build the file.
It depends on the age of the roof, how widespread the damage is, and how many times you have already repaired it. Typically, if the membrane is under 15 years old with isolated damage, repair makes sense. If seams are failing across the whole field, flashings are shot everywhere, and the insulation is wet, replacement usually wins on lifecycle cost. We walk the roof, show you the photos, and give you an honest recommendation either way in the written estimate.
In St. John, our inspections cover the full membrane surface, all seams and laps, flashing at parapets and curbs, penetration boots and pitch pans, edge metal and terminations, and drain function. We check for ponding areas, storm damage, hail bruising, and age related wear on the field. Everything gets photographed, and you get a written summary of what we found and what we recommend. No sales pitch, just what the roof is doing right now.
It depends on the scope and the weather. Most St. John commercial repairs are done in a day or two. Larger flashing rebuilds and sectional work typically take several days. Full replacements on multi tenant retail or office buildings usually run one to three weeks depending on square footage, tear off requirements, and access. We give you a realistic schedule in the written estimate and keep you updated if weather pushes anything.
Typically, there are two layers of coverage on a commercial roof. Materials carry the standard manufacturer warranty for the membrane or system you install, which varies by product. Our workmanship on the installation or repair is covered by our own workmanship warranty. We walk through both in writing before the job starts so a St. John property manager knows exactly what is covered and for how long. Ask during the inspection and we will lay it out.
In St. John, the first move after a storm is to look at the roof from a safe vantage point, note any obvious damage, and photograph anything visible from ground level or an adjacent building. Do not send tenants or staff on the roof. Call a commercial roofer to do a proper inspection and document the damage with photos your insurance carrier can use. Small storm damage gets worse the longer it sits. Schedule a free inspection and we will handle the rest.
Indiana Climate

Indiana Weather Affects Commercial Roofs Year Round

Indiana sees some of the most varied weather in the country. St. John property managers deal with spring hail and severe thunderstorms, summer UV exposure, fall wind storms, and winter freeze thaw cycles. Understanding these patterns is how we plan maintenance, repairs, and replacement work.

Wind-Lifted Membrane Seams

Straight line winds of 60 to 70 mph and higher rolled across St. John during the 2026 outbreak, and that is more than enough to peel TPO and EPDM at the seams and edge metal. Once a seam opens, water tracks under the membrane and the damage spreads fast. We reseal, replace damaged sections, and re secure edge metal when we are called out.

Hail Bruising On Membrane

Hail does not always punch a visible hole in a single ply membrane. It bruises the material, breaks down the reinforcement, and shortens the roof's life in ways you only see with a close inspection. On St. John commercial roofs we mark bruised areas, document them for your carrier, and recommend repair or replacement based on the density and severity.

Ponding After Heavy Rain

Flat terrain around St. John gives commercial roofs almost no help with drainage, and older buildings that have lost positive slope hold water for days after a storm. Ponding accelerates membrane breakdown, stresses seams, and eventually finds a way through. We identify pond areas, check drain function, and address the underlying slope or membrane condition.

Aging Flashings And Curbs

A large share of commercial roof leaks trace back to flashing at penetrations, HVAC curbs, and parapet walls, not the field membrane. The 2000 to 2020 building stock in this area is right in the range where lap adhesives and curb sealants start giving up. We rebuild flashings, reseal curbs, and extend the useful life of the roof before it becomes a replacement.

Material Guide

Choosing the Right Commercial Roof System in St. John

An honest breakdown of the three low slope systems we install most frequently.

TPO Membrane

TPO single ply membrane is the most common commercial roof surface in St. John today, and for good reason. It handles the low slope structural systems used on strip retail and office condos, reflects heat in summer, and welds into continuous seams that resist wind uplift when installed correctly. Owners choose TPO because it is cost effective per square foot, widely available, and straightforward to repair or patch when a section gets damaged. Most commercial buildings put up in Lake County since 2000 are already running some version of it.

Most specifiedReflective surface$$
EPDM Rubber

EPDM rubber membrane is the upgraded workhorse a lot of St. John property managers land on when they want longer service life and proven cold weather performance. It handles Northwest Indiana winters well, resists hail impact better than thinner membranes, and has a track record measured in decades on properly installed roofs. The tradeoff is a darker surface that absorbs more heat, so it is worth talking through the building's HVAC load before committing. On the right building, EPDM pays off for a long time.

Proven service lifeSimple repairs$$$
Standing Seam Metal

Standing seam metal is the premium long life option for commercial buildings in St. John, especially on sloped sections, canopies, and mixed use formats where appearance matters. Properly installed metal roofing can last 40 years or more, sheds water quickly, and handles high winds when fastened and detailed correctly. The tradeoff is upfront cost and the need for experienced installers who understand the flashing and expansion details. When the building supports it, the lifecycle math is hard to argue with.
