Thermoplastic polyolefin, better known as TPO, has earned its place on flat and low‑slope roofs across Burlington for one core reason: it solves problems our climate throws at buildings. Long freeze‑thaw cycles, lake effect wind, summer heat spikes, and the odd hailstorm ask a lot of a roof. Installed correctly, a TPO system handles ponding better than asphalt, reflects heat to tame cooling costs, and keeps seams tight through winter. Installed poorly, it can fail fast. If you are considering TPO roofing Burlington property owners have a right to expect an installation that respects local conditions and manufacturer specs. Here is how a professional project should unfold, what decisions drive cost and performance, and where experienced judgment matters.
Where TPO Makes Sense in Burlington
TPO suits flat roofing Burlington projects for commercial buildings, multifamily properties, and modern homes with low slopes. Its white reflective surface helps on large sun‑exposed roofs, cutting peak summertime roof temperatures by 30 to 50 degrees Celsius compared to dark surfaces. On retail plazas and warehouses along the QEW corridor, we routinely see cooling savings of 10 to 20 percent after switching from aged black membranes to bright TPO. On smaller residential roofs, savings vary more, but comfort and membrane longevity still improve.
The material is a single‑ply sheet, typically 45, 60, or 80 mils thick, welded at the seams with hot air. Properly welded seams turn two sheets into one homogenous layer, a detail that separates TPO from glued‑seam systems. In Burlington’s wind zones, that weld matters. I have seen mechanically fastened TPO stay put through storms that pulled up older ballasted systems.
TPO is not a cure‑all. If your roof is riddled with ponding dishes deeper than a finger over a 48‑hour span, you will need taper and drainage work that matters more than any membrane choice. If you have heavy foot traffic, a thicker sheet and walkway pads are not optional. If your roof hosts grease‑producing equipment, a grease containment plan is essential, because any single‑ply membrane, TPO included, dislikes constant hydrocarbon exposure.
How a Competent Burlington Roofer Approaches Assessment
Before the first roll goes up a ladder, a seasoned crew earns its keep during the assessment. For Burlington roofing projects, I look at three layers of risk: structure, moisture, and detailing.
Start under the skin. A proper roof inspection Burlington often involves infrared scanning or moisture meter readings on a dry evening, especially on larger commercial roofing Burlington footprints. We are looking for trapped moisture in the insulation or deck. Re‑roofing over wet insulation is a fast route to blisters and early failure. If scan data is ambiguous, selective core cuts tell the truth. I log insulation type and thickness, deck material, fastener pull‑out values, and any previous roof assemblies. In our area, steel and wood decks dominate, but older masonry and concrete show up on schools and industrial buildings.
Slope and drainage come next. Burlington’s freeze‑thaw pattern magnifies marginal slopes. On a so‑called flat roof, code minimum slope is 2 percent, but plenty of older roofs sag. Plan for tapered insulation, new drains, and scuppers that can move spring melt and summer cloudbursts. Many roof leaks blamed on “membrane failure” start as overmatched drains.
Finally, the details: parapet heights, coping conditions, deck edge metal, penetrations, skylight installation conditions, HVAC stands, and any abandoned equipment. A roof with six roof penetrations behaves differently from a roof with sixty. TPO shines on clean fields, but it earns its keep at the details.
If the building had hail damage roof Burlington residents often report in scattered storms, the inspection includes a close look at soft metals, flashings, and membrane bruising if a single‑ply is already present. Document everything for potential roof insurance claims Burlington adjusters will review later.
Repair, Recover, or Replace: Choosing the Right Path
Not every flat roof needs a full tear‑off. Choosing between roof repair Burlington, a recover, or roof replacement Burlington depends on moisture content, code, and economics. If core cuts show dry insulation, no more than one membrane layer is present, and the roof structure meets current load requirements, a TPO recover over a code‑compliant cover board can be smart. It keeps debris down and often shaves 10 to 20 percent off the project cost, while minimizing disruption for tenants.
If moisture is present, tear‑off becomes the responsible path. Wet insulation compromises fastener values and shortens the new assembly’s life. On tear‑offs, budget for deck repairs, especially on older wood decks that hid rot under a long‑term leak. This is where an experienced local roofing company Burlington building owners trust becomes crucial, because change orders can spiral when hidden conditions are mishandled. A transparent inspection report with photos, core cut logs, and a clear scope keeps surprises in check.
Emergency roof repair Burlington calls sometimes arrive after a storm with active leaks. In those cases, we stabilize first: temporary patches, drain clearing, and water diversion. Permanent solutions follow once the weather cooperates and we can open the assembly safely. For roof leak repair Burlington on single‑plys, solvent‑wipe prep and proper hot‑air welds on compatible patch material is the only fix I consider reliable.
Choosing the Right TPO Assembly
Three variables define a TPO roof’s behavior: membrane thickness, attachment method, and what sits under the membrane.
Membrane thickness, typically 45, 60, or 80 mil, trades initial cost for resilience. In Burlington’s climate, 60 mil is the workhorse, balancing cost with better puncture resistance and longer warranty options. I recommend 80 mil where foot traffic is heavy or hail exposure is frequent. The difference matters when someone drops a tool or after a March ice pellet storm.
Attachment methods include fully adhered, mechanically fastened, and induction welded plates. Fully adhered systems lay smooth in high‑visibility areas and resist flutter noise, which matters near bedrooms or offices. Mechanically fastened systems go down faster and can be optimal on tall buildings where adhesive windows are tight due to cold. Induction welding marries steel plates through the membrane with a heat induction tool, delivering strong wind uplift values with fewer fasteners showing at seams. The best choice depends on deck type, wind zone, and winter installation timing.
Under the membrane, the substrate can be a cover board over insulation or, in some recover scenarios, a prepared existing roof. Polyiso insulation remains standard for R‑value per inch, but in cold weather its practical R‑value can drift. I often install a thin layer of high‑density cover board, like glass‑faced gypsum, over polyiso to resist hail and foot traffic and to provide a stable welding surface. Where acoustic or fire ratings matter, design the stack to meet those needs.
If EPDM roofing Burlington systems already exist and are dry, a recover with a separator and TPO can work, but pay attention to compatibility, vapor drive, and adhesion. For metal roofing Burlington buildings with low slope, a TPO retrofit over flute fill and board insulation turns a heat‑soaked surface into a reflective, insulated deck while taming noise and leaks.
The Installation Timeline, Step by Step
For a typical 10,000 square foot commercial roof with straightforward access, plan on a two‑ to three‑week schedule from mobilization to final walkthrough. Weather can add days. The rhythm is benefits of licensed and insured roofers Burlington consistent.
First, mobilization and safety setup. Expect perimeter flagging, warning lines, staging for material, and a daily housekeeping plan. Same‑day roofing Burlington repairs might happen during this stage if active leaks exist.
Next, tear‑off or preparation. On tear‑offs, crews remove existing membranes in manageable sections to keep the roof watertight each night. Deck repairs happen as they appear, with photos and documentation. On recovers, the crew preps the existing surface, removes blisters, tightens fasteners, and installs any required separator layers.
Then comes insulation and taper. We set base layers, fit tapered pieces to direct water toward drains, and secure per manufacturer and wind‑uplift ratings. Expect an extra day or two on roofs with complex slopes or added drains. Roof ventilation Burlington details and attic insulation Burlington considerations apply more on sloped residential roofs, but on low‑slope assemblies, we still address vapor control and condensation risk case by case.
Cover board installation follows, then the membrane. Rolls are staged, laid out to reduce waste, and aligned to minimize cross‑seams. Seams are welded with calibrated hot‑air welders. A good crew tests weld settings each morning on scrap and cuts daily seam probes to ensure bond quality. Corners, curbs, and penetrations are flashed with pre‑formed or hand‑cut pieces, then welded and probed. This is where many installations rise or fall. I watch for clean substrate prep, correct weld temperatures, and enough bleed‑out at seams to indicate a full bond without scorching.
Edge metal is not decoration, it is a wind anchor. ANSI/SPRI ES‑1 rated edge systems are the standard, with cleats and fastener spacing matched to building height and exposure. Properly installed coping and drip edges keep wind from prying the roof up.
Water test and detail checks come next. We temporarily flood low points to confirm drainage, test scuppers and downspouts, and water‑test new roof drains. On commercial projects, a third‑party consultant may perform pull tests or observe critical stages.
Finally, cleanup, punch list, and closeout. You should receive a package that includes the manufacturer’s warranty registration, maintenance guidelines, a roof plan with drain locations and leak paths, and photos of hidden details. A roof warranty Burlington owners can rely on requires documented compliance with spec. I push for an owner walkthrough before demobilization, because it is easier to tune a detail while the crew is still on site.
How Weather Changes the Playbook
We work year‑round, but Burlington winters demand adjustments. Adhesive cure windows tighten below 5 degrees Celsius, which pushes us toward mechanically fastened or induction systems in cold months. Temporary heat tents at seams and curbs become part of the plan. If the forecast threatens rain or heavy snow, we reduce the daily open area and double up on night seals. Expect more frequent weather delays from late November through March, and a premium on scheduling during a dry run of days.
Summer heat introduces different constraints. Membrane handling on a white roof under full sun sounds minor until you have tried welding at noon in July. A professional crew shifts hours, works edges and detail zones in the morning, and welds field seams when temperatures stabilize. For projects with rooftop HVAC, coordinate shutdowns early, because crews and occupants both feel the heat.
Hail and storm damage roof repair Burlington projects often slot into a busy season. If your building sees a hail event, document the date, collect photos of soft metal dents, and call for a roof inspection Burlington within a few days. Insurance carriers tend to move faster when evidence is fresh and damage is quantified.
Cost, Bids, and What Drives the Numbers
New roof cost Burlington owners ask about most often lands within a range. For a straightforward commercial TPO system on a dry deck, you might see 9 to 15 dollars per square foot all‑in, depending on thickness, attachment, and access. Tear‑off, wet insulation disposal, tapered design, new drains, and heavy edge metal push costs higher. Occupied buildings with limited access, night work, or strict safety requirements add overhead. To control cost, target scope first rather than squeezing the last nickel out of labor. Value engineering without losing performance might include a mix of 60 mil field membrane and 80 mil walkways, induction fastening to reduce fastener counts and thermal bridging, or alternate cover boards where appropriate.
Request a free roofing estimate Burlington from multiple roofing contractors Burlington, but compare apples to apples. A low bid with no cover board, light edge metal, and minimal taper looks good on paper and leaks in year three. Ask each bidder to map seam spacing, fastener patterns, and detail sheets, not just square footage and warranty years.
For residential roofing Burlington owners with low‑slope sections tied into asphalt shingle roofing Burlington portions, scope coordination matters. Tie‑in details between shingles and a TPO cricket or low‑slope section require experience on both systems. Keep your metal roofing Burlington or shingle details in view during the bid process so the whole roof performs as a system.
Warranties and What They Really Cover
Manufacturers offer material warranties and, on approved installations, labor and material warranties that back both the membrane and the installation for a set term. Ten, 15, 20, and even 25‑year warranties exist, tied to membrane thickness, attachment method, and detail choices. Read the terms. Punctures from misuse, grease exposure, and unapproved alterations fall outside coverage. If a tenant adds rooftop equipment and cuts the membrane without the roofer’s involvement, warranty coverage can vanish.
A good warranty starts with a specification that the manufacturer approves and ends with a final inspection by their rep. Licensed and insured roofers Burlington businesses rely on will manage this process. Keep the closeout packet safe. If you ever need to file a claim, the serial numbers, photos, and inspection reports shorten the path to a resolution.
Details That Separate Good From Great
The biggest difference I see between average and excellent TPO roofing Burlington installations rests in water management and penetrations. Proper crickets behind roof‑mounted units shed water and keep ice from forming in winter shadows. Walkway pads steer traffic and prevent abrasion around service areas. Sizing and placement of overflow scuppers save interiors when drains clog. Pre‑fabricated corners and boots, when used and welded correctly, beat hand‑cut improvisation on complex shapes.
Edge metal that meets ES‑1 is a must, not a luxury. Insulation staggering and fastener patterns must match wind uplift requirements. On taller buildings near the lake, I increase perimeter fastening density and often recommend adhered perimeters even on mechanically fastened fields. The extra labor pays back the first time a winter storm tests the edges.
Air and vapor control matter in mixed‑use buildings. Without a proper vapor retarder, warm interior moisture can condense under the membrane in winter. Your roofer should ask about interior humidity, occupancy types, and ceiling conditions. Restaurants and pool facilities need special attention, as do buildings with high interior humidity and low dew points.
Gutter installation Burlington and soffit and fascia Burlington upgrades come into play on mixed roofs with adjoining sloped sections. Poorly sized gutters and downspouts can overload a low‑slope tie‑in. If you are upgrading, this is the time to right‑size drainage and ensure roof ventilation Burlington is not compromised at transitions.
Maintenance: Protect Your Investment
A TPO roof is not set‑and‑forget. Twice‑yearly roof maintenance Burlington programs catch small issues before they become leaks. Spring and fall visits should clear drains, re‑secure loose accessories, check seams and flashings, and inspect walkway pads. After severe wind or hail, request a quick check. Most roof warranty Burlington documents require documented maintenance, and it is simply prudent.
If your building has rooftop units, create a service path so HVAC technicians avoid wandering across the membrane. A 60 mil membrane with walkway pads can shrug off regular maintenance traffic, while an unprotected route across soft insulation will not. Train staff and tenants to report anything sharp or odd on the roof, from loose screws to dropped tools.
Grease and chemicals are the enemy. On restaurants and food processing buildings, install grease guards and schedule cleaning. TPO resists many contaminants better than some membranes, but long‑term exposure degrades any single‑ply. Catch it early and contain it.
Safety and Site Logistics You Should See
On a well‑managed project, you notice the safety culture. Daily tailgate meetings, controlled access to the building, material hoisting plans, and clean‑as‑you‑go housekeeping reduce risk for everyone. Pedestrian protection at entrances, coordinated with building schedules, keeps tenants safe. A plan for odor control during adhesive use matters in office and medical settings. Good crews post clear signage and communicate with building management. The best roofer Burlington property managers recommend will make the process feel orderly, even when weather plays games.
How TPO Compares to EPDM and Other Options
TPO and EPDM roofing Burlington systems both serve low‑slope roofs. EPDM remains strong where black membranes help with winter solar gain and where glue‑based seams make mechanical welding unnecessary. EPDM handles rooftop gardens well with the right assembly. TPO carries the edge in reflectivity for cooling, heat‑welded seams for consistent joints, and dirt shedding in early years. Modified bitumen still has a place for small roofs with complex penetrations and for crews set up to torch or cold‑apply. For roofs that see frequent foot traffic and tool drops, thicker TPO or a hybrid assembly with robust cover boards levels up durability.
On mixed roofs with asphalt shingle roofing Burlington on steeper sections and low‑slope returns, TPO bridges the gap. Metal roofing Burlington remains the long‑life champion on steep slopes, but once slope drops near flat, single‑ply wins on watertightness and detailing flexibility.
Working With a Local Team
Local knowledge matters. A local roofing company Burlington crews that have worked through our winters know how to phase work, when to avoid adhesive, and how to protect open edges before a lake‑effect surprise. They also know municipal rules, disposal sites, and noise bylaws that shape work hours.
When you engage roofing contractors Burlington property owners trust, look for clear documentation, manufacturer certifications, and a track record of both commercial and residential roofing Burlington work if your site blends both. Ask to see a roof they installed five or more years ago. Fresh installs look good in photos. Time is the real inspector.
If your property needs more than roofing, many building owners consolidate projects. Custom Contracting Roofing & Eavestrough Repair roofing teams in our area also coordinate eavestrough Custom Contracting Roofing & Eavestrough Repair upgrades, soffit and fascia Burlington work, and gutter installation Burlington so the envelope performs as a unit. Their custom-contracting.ca roofing and eavestrough custom-contracting.ca information can help you line up scopes, especially when roof drainage and exterior trim intersect. If you are planning doors Custom Contracting Roofing & Eavestrough Repair or siding Custom Contracting Roofing & Eavestrough Repair at the same time, coordinate flashing sequences and schedules to avoid rework. The same goes for skylight installation and roof leak repair Burlington after window or widnows Custom Contracting Roofing & Eavestrough Repair replacements. When trades coordinate, penetrations are sealed once and sealed right.
What to Expect Day to Day During the Project
Most owners want to know how the work will affect occupants. Roof noise is real, especially during tear‑off and when fasteners hit steel deck. Plan for loud days and communicate with tenants. Smells from adhesives can travel through rooftop intakes. A good crew will coordinate with your HVAC Custom Contracting Roofing & Eavestrough Repair technicians to shut down or filter intakes during those periods. Parking and crane days need coordination well in advance. If you need same‑day roofing Burlington emergency coverage, expect the crew to prioritize watertightness over speed on other tasks. Water wins every time.
Expect daily updates. Which sections will open and close, who is on site, and any schedule shifts due to weather should be clear. A foreman who answers the phone and a project manager who sends photos take stress out of the process.
Insurance, Permits, and Documentation
Storm damage roof repair Burlington often triggers roof insurance claims Burlington paperwork. Adjusters appreciate precise scope and evidence: core cut logs, moisture maps, hail impact photos on test squares, and a clear cost breakdown. Your roofer should help assemble this package. Permitting varies by scope. Full replacement with new insulation and deck work typically requires a permit. The roofer should handle it, and the inspection schedule should be part of your timeline.
Certificates of insurance should name you as additionally insured, and WSIB clearance should be current. Licensed and insured roofers Burlington standards protect you if a worker is injured or property is damaged. Keep copies on file.
Aftercare: Protecting the Warranty and the Asset
When the last seam cools, the work shifts to stewardship. Set a calendar reminder for spring and fall checks. Keep the roof access controlled. Label drains and keep them clear. If someone needs to install a new vent or run cabling, call your roofer to flash it. The cost of a proper curb and flashing assembly is trivial compared to chasing a leak through multiple suites.
Document any changes. If you sell the building, maintenance records add value and smooth any warranty transfer, which often requires a small fee and a form from the manufacturer.
Frequently Asked Questions From Burlington Owners
How long does a TPO roof last here? With 60 mil material, good detail work, and routine maintenance, 20 to 25 years is realistic. Thicker membranes and protected walkways push the upper end. Poor drainage shortens that fast.
Can TPO be installed in winter? Yes, with the right system choice and weather windows. Mechanically fastened or induction welded systems avoid cold‑sensitive adhesives. Expect longer timelines.
Will a white roof increase winter heating costs? The effect is modest on most commercial buildings. Short winter days, lower sun angles, and snow cover limit solar gain on flat roofs. The summer cooling benefit usually outweighs any winter loss.
Is TPO suitable for homes? On modern homes with low‑slope sections, absolutely. Tie‑ins to shingle or metal sections need careful detailing. Residential aesthetic concerns are often addressed with parapet caps and clean edge profiles.
What about vegetated roofs? TPO can work as part of a vegetated assembly when specified for root resistance and paired with protection layers. EPDM and PVC also see use in these assemblies. The design focus shifts to load, drainage, and maintenance.
Bringing It All Together
TPO done right is a system, not a product. Start with a hard look at the existing conditions. Choose membrane thickness and attachment to fit your building’s exposure and use. Solve drainage first, then perfect the details. Work with a team that documents, communicates, and respects both the manufacturer’s playbook and Burlington’s climate. Whether you need a quick roof leak repair Burlington, a thoughtful recover, or a full roof replacement Burlington with taper and new drains, the same principles apply.
If you are ready to explore options, line up a free roofing estimate Burlington with a local crew that has the credentials and the portfolio to back up their promises. Ask for references, a sample warranty, and a detailed scope with drawings. The roof over your head deserves more than a line item on a spreadsheet. It deserves the craft, planning, and follow‑through that keep water out, keep energy in, and keep your operations running regardless of what the lake sends our way.
