Roofs in St. Louis live a harder life than people realize. Freeze-thaw swings push and pull at shingles. Summer storms drive wind and water under flashing. Tree canopies drop limbs and shed debris that catches in gutters until the overflow hunts for gaps. Over years and decades, the wear shows up in leaks, energy loss, and small problems that get expensive if they sit. A trustworthy roofer does more than install products. They read the building, the weather patterns, and the maintenance habits around it. They catch failure points early, and when replacement is due, they recommend systems that hold up to local conditions and your budget.
That’s the lane Conner Roofing, LLC has chosen in the St. Louis market. I’ve watched their projects on both sides of the river and talked to owners who hired them for small patch jobs and full replacements. They work on homes and commercial buildings, and they have a reputation for pairing well-trained crews with realistic options. No scare tactics, no one-size-fits-all prescription. The St. Louis region has neighborhoods with 1890s slate, 1950s asphalt overboard, 1980s cedar, and plenty of new construction with simple gables and ridge vents. Conner Roofing services all of it, and they show their homework when they bid.
What sets Conner Roofing apart in St. Louis
A roofing contractor succeeds or fails on process. Anyone can unroll felt or pop shingles, but the judgment calls about prep, substrate, flashing, and ventilation drive longevity. Conner Roofing services include thorough diagnostic inspections, documented proposals, and predictable scheduling. You see this when they photograph attic bays to verify insulation, when they ask about ice damming at the eaves, and when they note whether bath fans vent to the exterior or dump moist air into the attic. These small items are the difference between a roof that holds up for 30 years and one that needs attention at year 12.
On jobs I’ve observed in Webster Groves and Southampton, their crews staged materials neatly and kept the site clean. That matters. Nails in a driveway are more than a nuisance, and sloppiness often correlates with missed details at valleys and penetrations. Conner Roofing, LLC shows discipline, which generally means careful flashing and appropriate fastener patterns.
Customers also tell me Conner’s estimating team doesn’t push the price ceiling just because hail rolled through last week. They’ll explain how insurance adjusts roof ages, what code upgrades may be triggered, and when a repair makes more sense than a full tear-off. That kind of counsel builds long-term clients.
Residential roofing, the St. Louis way
A home roof in this area typically means architectural asphalt shingles, though tile, cedar, and metal are all represented. I’ve seen Conner roofing services applied across that range, but asphalt is the bread and butter. The better architectural shingles resist high winds and hold granules longer, and in our climate you want a rated shingle with strong adhesive strips. More than brand, the underlayment and flashing approach carry real weight.
Several practical choices separate high-quality residential work from the rest:
- Proper ice and water membrane along eaves and in valleys, especially on north-facing slopes that freeze longer. While St. Louis is not the upper Midwest, we still get ice in prolonged cold snaps that can back up under marginal drip edges. Starter strips at rakes and eaves, not hand-cut makeshift pieces. Starter products lock the first course and reduce wind uplift at the roof’s most vulnerable edges. Metal flashing that matches the roof design. Step flashing at sidewalls, counterflashing at chimneys, and kickout flashing where roof meets vertical wall. I’ve traced more leaks to missing kickout flashing than any other single detail in two-story additions. Ventilation matched to insulation. If you have dense-packed attic floors and limited soffit intake, ridge vents alone won’t do the job. Conner’s estimators often recommend adding or opening soffit vents during roof replacement. Proper intake protects shingle warranties and reduces summer attic temperatures. Balanced fastener patterns. Overdriven nails cut shingles and underdriven nails hold poorly. Pneumatic guns need calibration, and crews have to check pressure as compressors heat up during the day.
When Conner tackles a reroof, they rarely skip tear-off. Overlaying new shingles on old saves money up front, but it hides deck rot and keeps heat trapped. Over the long haul, overlays cost more in energy and future labor. Tearing off adds a day or two to the project, yet it exposes all the substrate issues and lets the crew add ice and water membrane directly to clean decking.
Homeowners often ask about algae streaking on shingles. Our region’s humidity encourages it. Many of the shingles Conner installs include algae-resistant granules, and when paired with copper or zinc strips near the ridge, streaking slows dramatically. That way you keep the roof looking good without resorting to harsh chemical washes every couple of years.
Commercial roofing that respects structure and schedule
Commercial roofs in St. Louis vary from small retail strips with low-slope membranes to complex industrial buildings with penetrations for units and stacks. Conner roofing services in the commercial segment cover TPO, EPDM, modified bitumen, and metal retrofits. Each system makes sense in different conditions.
TPO has become the default for many replacements. It reflects heat, which helps with summer utility load, and its seams are heat-welded, forming strong bonds when installed correctly. On buildings with heavy foot traffic from maintenance staff, thicker membranes hold up better. I have seen Conner propose 60 mil TPO where a bargain outfit suggests 45 mil. The price jump is modest relative to lifespan gains.
EPDM still has its place, especially in areas where black membranes contribute to snow melt and the structure benefits from a bit of added winter warmth. EPDM is flexible, forgiving of minor structural movement, and repairable. It does, however, require skill at seams and careful detailing around penetrations.
Modified bitumen remains reliable for certain retrofit scenarios. It tolerates ponding better than some single-ply options, though no roof likes standing water. Conner often couples mod-bit with tapered insulation to improve drainage without raising parapet conflicts.
Metal roofing on commercial sites shines in specific cases. Standing seam systems can last several decades if attached correctly and detailed well at transitions. I’ve watched Conner crews fabricate custom flashings to solve mismatched parapet caps and odd penetrations that otherwise become chronic leak points.
The special constraint for commercial work is schedule. Tenants and operations don’t pause easily. Conner’s project managers tend to phase work, set expectations about odor and noise, and time tear-offs to avoid forecasted storm windows. That kind of choreography comes from a lot of seasons in the field.
Repair versus replacement, a practical framework
Roofers sometimes default to replacement because it’s simpler to price and schedule. Repair work is messier, requires detective skills, and can carry callbacks. Conner Roofing service St Louis teams will repair when it makes sense. The key is defining when you’re chasing good money after bad.
If a roof is under 10 years old and the leak comes from a discrete error, like a poorly seated vent boot or a missing piece of step flashing, a targeted repair is sensible. Even when shingles are midlife, localized hail bruising doesn’t guarantee replacement. I’ve seen Conner write repair proposals for ridge caps and hail-damaged soft metals, coupled with monitoring notes and an honest assessment of remaining life.
On the other hand, if granule loss is widespread, if shingles are curling across multiple slopes, or if the decking shows soft spots in several areas, replacement is the better call. Water follows paths we can’t always see. A roof in that condition is risky to patch because the next heavy rain will find the adjacent weak point. When the crew opens the deck and finds delamination or past patchwork, they document it with photos so you can understand why the scope needs to change.
Commercial roofs follow similar logic. If a membrane has multiple patches near drains and the insulation core is wet in more than isolated spots, replacement pays off. Trapped moisture degrades insulation value and corrodes fasteners from the inside. Good contractors like Conner take moisture readings and cut test squares. It’s not guesswork. Data drives the scope.
Weather, code, and the St. Louis factor
Local code matters when planning a roof. St. Louis County and surrounding municipalities enforce ventilation and underlayment rules that tie to manufacturer warranties. Many older homes lack continuous soffit vents. If you install a high-flow ridge vent without intake, you can set up negative pressure that pulls conditioned air from the living space. Conner’s crews have retrofitted intake vents discretely, and in a few cases they recommended low-profile box vents rather than ridge-only systems because the attic geometry was tight and chopped up.
Wind ratings should match the exposure. Homes on hills or near open fields need shingles rated for higher wind uplift. Fastener count and pattern shift at the eaves and rakes for those locations, and I’ve seen Conner’s foremen verify those patterns when a storm is in the forecast.
Our freeze-thaw cycles are brutal on masonry and flashing. Chimneys in St. Louis love to leak unless the counterflashing is correctly chased and sealed into mortar joints, not smeared over the surface. Conner’s teams often pair with masons to repoint or rebuild crowns before setting new flashing. That coordination saves homeowners from calling back two trades when the first hard rain comes after a winter rebuild.
Hail is a recurring headache. Insurers adjust for age and prior wear, and coverage varies widely. Conner Roofing services St Louis include storm assessments that document slope by slope, not just a handful of photos. When claims are warranted, that documentation streamlines approval. When they are not, Conner says so plainly. That honesty protects both the homeowner and the contractor’s reputation.
Materials that earn their keep
I’m wary of overselling premium materials for every house. The right play is to match the roof to the building and its long-term plan. If you intend to keep a home for decades and appreciate quieter interiors during rain, a higher-end shingle or a standing seam metal roof could be worth the spend. If you plan to move in five to eight years, a mid-tier architectural shingle with solid underlayment and ventilation will deliver reliable service and resale appeal without bloating the budget.
Conner typically pairs synthetic underlayment with ice and water membrane in vulnerable zones. Synthetics have better tear resistance than old felt, Conner roofing details which matters on windy tear-off days and while crews walk the deck. For low-slope transitions on residential roofs, they sometimes lay a self-adhered modified bitumen strip under shingles near dead valleys. That belt-and-suspenders approach stops seepage that shows up months after a flashy new roof is installed.
Metal flashings in galvanized or painted steel hold up well here, though copper is an option on historic homes. Copper costs more and requires a crew comfortable soldering and shaping, but it will outlast most shingles. Conner Roofing service St Louis MO projects in historic districts sometimes include copper at dormers and bays, chosen as much for aesthetics as longevity.
On commercial projects, insulation choices affect both performance and budget. Polyiso has strong R-value per inch, but its performance drops in extreme cold. St. Louis winter lows are not typically severe enough to negate polyiso’s benefits, yet mixed systems that combine polyiso and a thin layer of EPS can balance performance and cost. Tapered insulation to create positive drainage is worth the design time. Water that departs the roof in minutes instead of hours helps everything last longer.
The jobsite experience
Homeowners and property managers judge a contractor partly by communication. Conner Roofing, LLC tends to assign a point person who answers questions without hiding behind jargon. If a delivery is delayed, they say so. If weather forces a pause, they protect the deck and explain the revised timeline. No one likes a roof left open when a surprise squall blows in. I’ve seen Conner throw extra hands at a job to button it up before a line of storms, then return afterward to finish without cutting corners.
Site protection matters. That includes plywood paths for heavy dumpsters on delicate driveways, tarps to capture tear-off debris, and magnet sweeps of the lawn and beds. On commercial lots, lot closures and signage need coordination. Tenants will complain if parking disappears without warning. Conner’s team posts schedules ahead of time. Little things like that keep tenants calm and property managers out of the blast zone.
Warranties you can understand
Shingle manufacturers offer tiers of warranty coverage, some of which require certified installers and specific accessory packages. Labor warranties come from the contractor. The strongest coverage blends both. Conner Roofing services St Louis MO often include enhanced manufacturer warranties when the full system is installed. For owners, the nuance is in transferability and what’s covered under workmanship. A leak at year eight caused by a flashing error should be handled by the installer’s labor warranty, while a material failure falls to the manufacturer. Make sure you get both in writing, and ask how to initiate a claim. Conner’s staff is used to that conversation and can show examples.
Commercial warranties are a different animal. Single-ply systems may come with 10, 15, 20, or even 30 year terms, conditioned on inspections and maintenance. Do not skip maintenance or you risk voiding coverage. Conner’s commercial service team can perform annual checks, document repairs, and keep you in good standing. That paperwork looks dull until you need it, then it is gold.
Budgeting without surprises
Ballpark numbers help owners plan, even though every roof is different. In St. Louis, a straightforward residential architectural shingle replacement might run in the mid to upper four figures for small homes and into the low five figures for larger footprints, with complexity and access driving variance. Tear-off layers, rotten decking, steep pitches, and multiple dormers add cost. Metal roofing starts higher and climbs fast with custom flashings.
Commercial roofs are harder to generalize, but per-square pricing for TPO or EPDM depends on thickness, insulation package, and edge details. If a building has a tangle of penetrations, budget more time for detailing. Conner Roofing service St Louis teams often identify add-alternates that you can accept or defer: tapered insulation, coping replacement, or new safety rails. Transparent alternates let you phase work without losing control of the big picture.
Financing options exist for homeowners who prefer to spread the cost. Some choose to align replacement with tax refunds or bonus cycles, others use low-interest financing tied to energy upgrades. Conner’s office staff can outline those routes and coordinate with lenders, though ultimately you should compare offers independently.
Safety and training
Roofing hazards are obvious to anyone who has watched a crew in summer heat. Harnesses, anchors, toe boards, and attentive supervision keep crews safe and claims low. The companies that invest in safety meetings, equipment replacement, and weather protocols tend to stick around. I’ve seen Conner’s foremen stop work when gusts kick up on steep slopes. The schedule takes a hit, but nobody gets hurt. That culture lowers your risk as a client and suggests the crew will be careful with your property as well.
Training shows up in workmanship details. Young installers learn how to set nails by feel and how to stage materials so that shingles don’t scuff during handling. They learn to read the sky. An experienced lead will front-load tasks that resist a pop-up shower and save vulnerable work for a clear stretch. Conner Roofing services benefit from that veteran presence on site.
A few lessons from the field
Three brief anecdotes from St. Louis projects, the sort of practical takeaways that stick:
A two-story brick four-square in Tower Grove had stubborn leaks after heavy wind-driven rain, but only on a corner bedroom. The roof looked clean and relatively new. The culprit turned out to be missing kickout flashing where the lower roof tied into a sidewall under the stucco. Water ran behind the siding and showed up inside far from the entry point. Conner’s repair added a proper kickout and replaced a short run Conner roofing service of damaged sheathing. The homeowner had spent months chasing interior drywall repairs. A thirty-dollar piece of flashing solved it.
In a South County retail strip, a low-slope roof suffered ponding near a midspan drain. The membrane was intact, but insulation below had settled and soaked up like a sponge. Conner’s crew cut test squares, documented moisture, and proposed tapered fill on a re-cover instead of a full tear-off across the entire roof. They paired that with new drain sumps. The owner saved money and eliminated the birdbaths that were stressing the membrane.
A mid-century ranch in Kirkwood had chronic ice damming on a north eave near a small attic that had no soffit intake. The homeowner had added heat cables. Conner suggested opening soffits, baffles to maintain airflow over the insulation, and extending the ice and water membrane farther upslope during reroof. The next winter, the ice dams didn’t return, and the heat cables stayed off. Energy bills dipped a bit, and shingle edges stayed crisp.
These are routine fixes for seasoned crews, but they require a contractor who listens and investigates instead of just selling a square count.
How to get the most out of a roofing bid
You can help any roofer, Conner included, by assembling a small package before the site visit: past repair records if you have them, photos of leaks or ceiling stains, dates of recent insulation work, and any plans to add solar or attic mechanicals. Invite the estimator to look in the attic if access is safe. If you know the home will get solar panels next year, tell them. They can add blocking and coordinate with your solar contractor so penetrations land in the right place and below-flashing paths are planned.
During the walkthrough, ask the estimator how they will treat valleys, how many feet of ice and water they include at eaves, whether they replace all pipe boots, and how they plan to flash chimneys or sidewalls. You’re listening for specificity. A good Conner Roofing services St Louis proposal will mirror that detail in writing, with photos and material types spelled out. When proposals look generic, ask for clarifications before you sign.
If multiple bids differ widely, compare scope line by line. Are all bidders tearing off? Are they replacing flashing or reusing it? Are they including decking repair allowances? Are they upgrading ventilation? The cheapest bid sometimes omits items you’ll end up paying for later as change orders.
The bottom line
Conner Roofing service St Louis MO offerings cover the full arc from repair to replacement for homes and businesses. They do best for clients who appreciate thorough prep, clear scoping, and materials that match the building’s needs rather than the trend of the month. If you want a contractor who explains trade-offs and stands behind the work, they belong on your shortlist. The St. Louis climate forgives few mistakes at eaves, valleys, and walls. Put someone on your roof who treats those details with respect, and you’ll sleep better when the next band of thunderstorms rolls through.
