Commercial Roofing Service: Maintenance Tips from Montgomery Roofing - Lorena Roofers
Commercial roofs don’t often fail from a single dramatic event. They usually give up in a slow, predictable way: a seam loosens, water finds a pinhole, a drain clogs, and the moisture trapped underneath cooks in the Texas sun until it telegraphs through as a blister or stain. The good news is that most of this is preventable with disciplined maintenance and a clear plan. After decades on rooftops across Central Texas, our team at Montgomery Roofing - Lorena Roofers has learned where the trouble starts, how to spot it early, and how to stretch every year of service life from the roof over your business.
This guide pulls together practical, field-tested maintenance advice for commercial roofing service. It’s written for building owners, facility managers, and anyone who has to answer for leaks, commercial roofing service energy costs, and replacement budgets. We’ll talk materials and climate, routine schedules, forensic inspection techniques, documentation that actually helps, and the line between DIY tasks and professional work. You’ll find a few local anecdotes from Lorena and Waco jobs where the smallest maintenance habits paid off in big ways.
What Texas heat and storms do to a commercial roof
Central Texas gives roofs a workout. On a summer day, a white TPO membrane might surface at 120–140°F, while black EPDM or modified bitumen can spike past 160°F. After sundown, that same surface drops 40–60 degrees. This thermal swing flexes the membrane, stretches seams, and tests fasteners. Now add spring hail, fall cold fronts, and the occasional straight-line wind, and you’ve got a cycle that attacks any weak spot.
UV exposure dries out asphalt binders in modified bitumen and ages plasticizers in PVC. Hail spalls granules off capsheets and bruises insulation. Wind uplift focuses at edges, corners, and around rooftop equipment where detailing is most complex. If your roof sees foot traffic from HVAC techs or telecom contractors, abrasion and dropped tools become their own category of damage. Maintenance isn’t a nice-to-have in this environment; it’s the only way to keep the system watertight and efficient across the lifespan you built into the budget.
The materials on your roof and what they need
Two roofs can look similar from the parking lot and behave very differently under stress. Maintenance must respect the chemistry and detailing of the actual system.
TPO and PVC single-ply membranes rely on heat-welded seams. Their strength comes from proper welds and intact surfacing. Regular maintenance checks weld continuity, flashings at penetrations, and reinforcement patches at high-stress areas like corners and curb tops. White membranes reflect heat, which helps energy bills, but they also show dirt and biological growth that can mask cracks or punctures.
EPDM is a rubber membrane usually seamed with tapes or adhesives. It tolerates thermal movement well, but its seams and terminations are vulnerable to adhesive failure over time, especially when ponding water or debris lingers. EPDM repairs often require meticulous cleaning and prime-and-patch techniques that succeed or fail on surface preparation.
Modified bitumen and built-up roofs (BUR) are asphalt-based. Their granular surfaces protect the bitumen from UV. Lose enough granules and you accelerate aging. Lap integrity, plies at transitions, and cap sheet conditions carry the day. Mastic slathered around a boot may last a season; a properly reinforced flashing detail can last years.
Metal roofs shed water effectively and move a lot with temperature swings. Fasteners back out, seams loosen, and penetrations need specialized boots that can flex. A metal roof’s best friend is a disciplined check of fastener torque, sealants at terminations, and attention to panel coatings.
Knowing your system makes every inspection more surgical, and it speeds up repairs because the right materials and methods are on the truck when you need them.
Maintenance cadence that actually works
We recommend a rhythm that matches the climate and your business operations. Twice a year is a sensible baseline in Texas: once in late fall after storm season and summer heat, and again in early spring before severe weather returns. Add quick checks after significant weather events, especially hail or high wind.
For large facilities, we group roofs by risk. Buildings with aged membranes, heavy rooftop equipment, or complex penetrations get quarterly attention. Newer roofs with clean layouts can often maintain the semiannual schedule. If you’ve just replaced a roof, the first two years matter even more: small punch-list items can masquerade as warranty claims later, and catching them early keeps you square with the manufacturer.
What a thorough inspection looks like from our side of the ladder
A good inspection starts before we touch the hatch. We review the roof plan, previous reports, warranties, and any leak calls since the last visit. On-site, we look at access safety first, then walk the perimeter clockwise and work inward in lanes so nothing gets missed. The goal is to identify active leaks, soon-to-fail details, and maintenance that will pay for itself.
Perimeter and terminations tell the truth. We check edge metal for secure attachment, look for face fastener back-out, and confirm that cleats and straps remain intact. On single-ply, we probe welds at corners and around drains. At walls, we look for loose counterflashing, gaps at reglets, and separation where the membrane turns up.
Penetrations are leak magnets. HVAC curbs, pipe boots, pitch pans, cable penetrations, and skylight curbs get close inspection. On TPO/PVC, we test welds around corners and review the integrity of preformed boots. On EPDM and modified bitumen, we check tape or adhesive at laps and the condition of mastics. For metal roofs, we evaluate closure strips, foam seals, and movement at penetrations.
Water management is next. Drains must be clean, strainers intact, and sumps properly depressed. On low-slope roofs, we note ponding areas and measure their depth and duration if water is present. Any ponding over 48 hours after a rain suggests a slope or drain issue worth correcting. Scuppers should be clear and discharge away from walls and sidewalks where staining can suggest backflow problems.
The field of the roof matters too. We look for punctures, blisters, wrinkles, and membrane shrinkage. On modified bitumen, blisters might be left alone if they’re not in a traffic path and remain stable, but any blister at a seam or near a penetration deserves attention. On single-ply, we check for surface oxidation and chalking, which opens the door to cracking under stress. We note any soft spots that suggest wet insulation. Infrared scans after sundown can map trapped moisture for targeted repairs instead of wholesale replacement.
Rooftop traffic patterns leave a signature. We look for scuffs and crushed insulation boards around serviceable equipment. If walk pads are missing or misaligned, we recommend adding or repositioning them. A $10 pad in the right place can save a $2,000 repair when a technician drops a panel or steps off a curb onto hot membrane.
Documentation seals the value. We produce a photo log with annotations, a plan drawing with keyed locations, and a prioritized scope: immediate repairs, near-term maintenance, and capital planning items. A budget figure next to each line helps facility managers make the case internally. Over time, this file becomes the roof’s medical chart, not just a stack of invoices.
The call you make after a storm
After a hailstorm, don’t assume the absence of a leak means the absence of damage. Hail can bruise insulation beneath intact membranes. On modified bitumen, loss of granules exposes asphalt to UV and speeds aging. For metal, dents may be cosmetic, but if seams are compromised or protective coatings are cracked, corrosion starts. We advise a targeted post-storm assessment within a few days. Document everything while footprints on the roof still show, then decide whether to file a claim. Insurers respond best to evidence: dated photos, hail size estimates, measured dent fields, and a professional report. Filing late or without specifics often leads to unnecessary disputes.
Ponding water: a slow, solvable problem
Many low-slope roofs have low spots. The question is whether they hold water long enough to cause damage. Extended ponding accelerates membrane degradation, loads the structure, attracts debris, and grows biological films that hide defects. On existing roofs, we’ve solved ponding by adding tapered crickets to divert water, clearing debris that plugs a scupper’s throat, or lowering a drain bowl to restore sump depth. Sometimes the fix is as simple as removing an abandoned pitch pan or conduit that dams water along a parapet. If you plan a reroof in a few years, an interim solution like strategic walk pads can keep foot traffic off wet zones and stop punctures in their tracks.
The hidden cost of dirty roofs
A dusty white membrane doesn’t reflect like it used to. We’ve measured surface temperatures on uncleaned TPO roofs running 15–25°F hotter than after a gentle wash. That heat ends up in your HVAC load. Regular cleaning, done with low-pressure rinse and cleaners approved by the membrane manufacturer, restores reflectivity and reveals defects the dirt was hiding. Avoid power washing with high-pressure wands; they can scar membranes and force water into seams and under flashings.
Flashings and the small parts that carry big risk
Most leaks start at terminations, not in the field. Flashings at walls and penetrations deserve outsized attention. Poorly detailed corners, split mastic at a pipe, or a loose counterflashing can turn a sprinkle into a ceiling tile disaster. We often upgrade vulnerable transitions during maintenance: swap aged pitch pans for mechanically secure boots where possible, add reinforcement patches at curb corners, and install metal counterflashings where the original design relied on sealant-only barriers. On metal roofs, we replace compressible closure strips that have stiffened and lost shape. The cost of these preventive steps is modest compared to downstream damage to insulation, decking, and interiors.
Rooftop equipment and the people who service it
The roof is a workplace for other trades, and their habits influence your leak history. We’ve followed the same scuff marks to the same unit on repeat calls. A few practical steps make a difference. Provide clear walk paths from the hatch to all serviced units. Label equipment curbs and keep tools like pavers or spare pads near high-traffic areas. Coordinate with HVAC and telecom contractors so they understand the roof’s vulnerabilities. Require that they report any damage immediately. Not every trade thinks in waterproofing details; a small orientation at the start of a project can save you hours of leak tracing later.
Documentation that saves money
If your team handles some routine tasks, train them to capture the right details. It helps to keep a simple roof file with a few essentials: the original install documentation and warranty, plan drawings and roof age by area, a log of all leaks with dates and locations, photo records from every inspection, and a list of rooftop equipment with service dates. When we see a well-kept file, we diagnose faster, advocate more effectively with manufacturers and insurers, and avoid duplicating work. A one-page summary of conditions and priorities each year keeps decision makers focused.
Repair versus replacement: reading the signs
No one wants to replace a roof early, but there is a point where chasing leaks costs more than a planned retrofit. We weigh several factors. Age relative to expected lifespan matters, but condition matters more. If moisture mapping shows widespread wet insulation, patching becomes a stopgap. If seams on a single-ply are failing across the board or if asphalt plies are brittle and cracking, the curve is bending toward replacement. The building’s use is critical too. A data center or medical facility bears a different risk profile than a warehouse. Occupancy changes can justify earlier replacement to secure reliability and improve energy performance.
Roof-over systems, such as installing a new single-ply over a dry, stable existing roof with a proper separator layer, can control costs. But they require thorough moisture scans and attention to building code limits on the number of roof layers. Don’t assume a recover is the answer until you confirm substrate condition and load capacity.
Energy performance as a maintenance goal
A healthy roof reduces energy costs two ways: it reflects heat when designed to do so, and it preserves the R-value of the insulation below by staying dry. Wet polyiso loses a large share of its insulating power. The cheapest energy retrofit can be stopping a small leak that’s soaking a four-by-eight board every time it rains. We’ve seen clients drop peak summer cooling loads after restoring reflectivity with an approved wash and coating system. Not every roof qualifies for coating, and compatibility is specific to chemistry, age, and adhesion, but when it fits, it can add years of service and improve efficiency.
Safety and compliance without slowing the job
Maintenance plans should incorporate OSHA-compliant access and fall protection so inspections and repairs don’t get delayed. Fixed ladders, guardrails at frequently accessed areas, and designated tie-off points allow teams to work quickly and safely. Keep clearances around electrical service, antennae, and gas lines. When we see improvised access or obstructed paths, we flag it because safety issues tend to correlate with deferred maintenance elsewhere.
What you can handle in-house and when to call us
Many facility teams do a fine job with basic housekeeping: keeping drains clear, removing debris, checking that protective walk pads stay in place, and reporting suspicious stains on ceilings right away. They can also snap photos after storms and keep the roof file current. The moment you move into seam work, flashing repairs, infrared moisture mapping, or hail assessments, it pays to bring in a commercial roofing service that does this every day. Manufacturer warranties often require that certain repairs be performed by certified installers to keep coverage in force. A well-meaning repair with the wrong cleaner, roller, or primer can cause more trouble than it solves.
A small Texas anecdote about timing
A few summers back in Lorena, a client with a 60-mil TPO roof called about a persistent musty odor in a conference room. No visible stains, no active drip. Our tech found a clogged internal drain where the strainer had been knocked off during HVAC service. Water had been ponding around the sump, then seeping under the membrane at a poorly welded seam only when storms coincided with northerly wind. Thermal imaging at dusk mapped a damp circle about eight feet across. We cleaned the drain, re-welded and reinforced the seam, and replaced the strainer. The repair took two hours. Had they waited for a ceiling stain, that moisture would have spread, softened the insulation, and likely would have prompted a warranty fight. Timing matters.
Practical steps to put on your calendar
Schedule semiannual professional inspections in early spring and late fall, with quick checks after major storms. Keep drains and scuppers clear, and photograph the condition after each cleaning to build a record. Maintain walk pads to and around all serviceable equipment; add pads where scuffs or traffic marks appear. Document every leak with a date, location, photos, and weather conditions; patterns tell the story. Review warranties and approved materials before any repair; compatibility protects coverage.
These five habits cost little and prevent most surprises we see in Central Texas.
How maintenance supports capital planning
A roof in good shape gives you flexibility. If you know the membrane condition, moisture profile, and detail integrity, you can plan the next reroof on your terms rather than in the middle of a crisis. This affects cash flow, tenant coordination, and the chance to time the project in shoulder seasons when crews move faster and weather risks drop. A modern replacement plan can incorporate better insulation, upgraded edge metal for higher wind ratings, and smarter details at parapets and penetrations. Spread across the next decade, these choices lower operating costs and reduce risk.
Why choose a local team
There is a practical advantage to working with a contractor who spends every week on roofs from Lorena to Waco and beyond. We know the way a north wind drives rain under certain edge details, the hailstones that typically fall in spring, and the construction practices common in this area from builds in the 1990s versus the 2010s. That familiarity shortens diagnosis time and informs better decisions about repairs, coatings, and replacements. When you search for roofing services near me or the best roofing services, look for those who can articulate the local patterns and back it up with photos and references, not just a list of materials.
A note for mixed-use property owners
Many portfolios combine commercial and residential buildings. While we focus on commercial roofing service here, the maintenance mentality carries over. Residential roofing service on steep-slope systems needs its own cadence and detail care, especially after hail. The interplay matters when a mixed-use building has both flat and pitched sections; flashings where these systems meet need special attention. Keeping one contractor accountable for both can simplify leak triage and documentation.
When coatings make sense, and when they don’t
Elastomeric coatings can extend the life of certain roofs, improve reflectivity, and help control minor cracking. They are not a cure-all. A coating over saturated insulation traps moisture and accelerates failure. Over aged single-ply with poor adhesion, coatings can peel. Over metal, a well-prepped and properly specified system can stop minor leaks at fasteners and seams and delay replacement for years. The decision should follow adhesion tests, moisture scans, and confirmation of manufacturer coverage for the system you’re creating, not just the liquid in the pail.
Warranty realities
Manufacturer warranties vary widely. Some cover materials only; others are NDL (no dollar limit) for both materials and labor. Most require documented maintenance and prompt notice of leaks. They also outline approved repair methods and materials. A quick patch with a non-approved mastic can void coverage for that area. We help clients interpret these terms, align maintenance with requirements, and submit the right documentation when a claim is warranted. The warranty is a tool, not a guarantee against neglect.
The bottom line: what successful maintenance buys you
Done right, maintenance buys time, predictability, and lower total cost of ownership. We’ve seen 20-year roofs reach 25–27 years with disciplined care, especially when high-risk details are upgraded proactively. We’ve also seen roofs that should have gone two decades fail in 12 because drains were never cleared and ponding rotted seams. The difference shows up in energy bills, tenant satisfaction, and the number of emergencies you juggle in storm season.
