Most roof problems don’t announce themselves. They develop quietly — a slow leak tracking through insulation, granules shedding season by season, flashing separating millimetre by millimetre — until the day water appears on your ceiling and the problem is already expensive. A professional roof inspection from United Roofers tells you the truth about your roof before that day arrives.
We provide certified roof inspections for homeowners and commercial property owners across Ontario — combining visual assessment, thermal imaging technology, and 20+ years of local experience to deliver an honest, documented picture of your roof’s actual condition. Whether you need a pre-purchase inspection, a seasonal check, post-storm assessment, or a custom maintenance plan, we’re equipped to help.
Our initial site visit and estimate is always free. The detailed inspection report — thermal imaging data, photos, written findings, lifespan estimate, and repair recommendations — is a professional paid service that gives you the documented accuracy to make real decisions.

Ontario’s climate is one of the most demanding roofing environments in the world. Heavy snow loads through winter, aggressive freeze-thaw cycling from November to March, summer hailstorms, wind events, and high humidity all work on your roof simultaneously — often in ways that aren’t visible until the damage is already done.
The cost of skipping inspections:
The value of catching problems early:
A professional inspection with United Roofers pays for itself in the first problem it catches.
We’re transparent about how our service works:
When you call us, we schedule a no-obligation site visit at your convenience. During this visit, we assess the general condition of your roof, answer your questions, and give you an honest overview of what we’re seeing. This is entirely free — no pressure, no invoice.
If you need a quote for repair or replacement, we provide that in writing at no charge.
When you need documented, detailed findings — for a real estate transaction, an insurance claim, a maintenance decision, or simply peace of mind with full accuracy — our professional inspection goes significantly deeper:
This is the inspection that matters when you’re buying or selling property, managing a maintenance program, or making a capital planning decision on a commercial building.
Every United Roofers inspection follows a complete, methodical process — inside and out:
Roofing Material Condition We assess the full surface of your shingles, membrane, or metal panels — checking for granule loss, cracking, blistering, curling, lifting, missing sections, and end-of-life wear patterns. Different materials fail differently, and we know what to look for in each system.
Flashing Integrity Flashing is the leading source of roof leaks — at chimneys, skylights, vents, dormers, wall joints, and penetrations. We inspect every flashing point for separation, corrosion, sealant failure, and gaps that allow water entry.
Thermal Imaging — Finding What Eyes Miss Water enters at one point and travels before it drips. It saturates insulation and tracks along decking, appearing inside far from its true origin. Our thermal imaging cameras detect the temperature differentials created by trapped moisture and wet insulation — mapping the actual entry point and the extent of existing moisture damage. This precision changes what repair looks like: instead of patching symptoms, you fix the actual problem.
Roof Structure and Decking We check for soft spots, sagging, and signs of moisture intrusion in the structural deck — especially critical on older properties where original board sheathing may have absorbed years of slow moisture. A structurally compromised deck changes the recommendation from repair to replacement.
Attic Ventilation Proper airflow between soffit and ridge vents determines ice-dam risk in winter and moisture accumulation in summer. We assess intake and exhaust balance — because inadequate ventilation is the leading cause of premature shingle aging and the ice-dam formations that cause significant eave damage across Ontario’s winters.
Drainage System Gutters, downspouts, and surface drainage flow all affect how water leaves your roof. Blocked or undersized eavestroughs contribute to fascia rot, foundation moisture, and roof-edge ice formation. We check the full drainage path and flag issues.
Seals and Penetrations Every point where pipes, vents, skylights, or equipment penetrate the roof surface is a potential entry point. We inspect all seals and rubber pipe boots for cracking and deterioration — a common failure point on roofs approaching 15+ years.
A roof inspection before a real estate transaction gives buyers documented, independent confirmation of the roof’s condition and remaining lifespan — before committing to a purchase. For sellers, a clean inspection report removes buyer objection and supports the asking price. Our written report with photos is accepted by real estate professionals throughout Ontario.
Storm and hail damage is often invisible from the ground until it causes a leak weeks or months later. After any significant weather event — high winds, hail, ice storms — a professional inspection documents actual damage while it’s fresh, which is essential for insurance claims.
Ontario’s freeze-thaw winters demand that your roof enter the season with solid flashing seals, functioning drainage, and adequate attic ventilation. A pre-winter inspection identifies vulnerabilities while they’re still inexpensive to correct.
Many property owners — particularly those with commercial buildings and older residential properties — schedule annual inspections as standard maintenance. The cost is consistently lower than the smallest emergency repair it prevents.
Most asphalt shingle roofs in Ontario approach end of life between 15 and 25 years. An inspection at the 15-year mark gives you accurate information on remaining life — the difference between budgeting for replacement next year vs having 7 more years before action is needed.
When a roof event occurs, insurance adjusters need documented evidence. Our inspection reports — written findings, thermal imaging data, and photo documentation — provide the professional documentation that supports your claim and prevents disputes over damage scope.
A one-time inspection tells you where your roof stands today. A maintenance program keeps it performing for its full lifespan.
United Roofers builds custom maintenance plans tailored to each property — based on roof age, material type, building use, and inspection findings. A maintenance program typically includes:
Scheduled inspections — annual or bi-annual visits with written reports documenting condition changes over time, giving property managers and owners a clear record of asset performance
Drainage maintenance — clearing gutters, downspouts, and scuppers before blockages cause ponding or ice-dam conditions
Flashing and seal checks — identifying and sealing early-stage separation before water finds the gap
Post-storm response — priority visits after significant weather events to assess and document damage
Priority scheduling for repairs — maintenance plan clients receive priority booking for any repair work identified during inspections
Custom maintenance programs are available for both residential and commercial properties. For commercial property managers overseeing multiple buildings, we develop portfolio-level programs with consolidated reporting.
📞 Call (905) 789-1335 to discuss a custom maintenance plan.
We inspect both residential and commercial properties — and the approach differs:
Residential inspections focus on shingle or metal condition, attic ventilation, flashing integrity at common residential penetrations (chimneys, skylights, vents), and drainage through residential eavestrough systems. Most residential inspections are completed within one to two hours.
Commercial inspections require additional scope — large flat or low-slope membrane systems need systematic thermal imaging coverage across the full roof area to locate infiltration points. Drainage design, HVAC penetration sealing, and parapet wall condition all require specific attention. Commercial inspection timelines depend on building size and system type.
Both residential and commercial inspection reports include the same deliverables: written findings, photo documentation, thermal imaging data where applicable, lifespan assessment, and prioritized recommendations.
Step 1 — Free site visit Call (905) 789-1335) to schedule. We visit your property, conduct an initial assessment, and answer your questions. No charge, no obligation.
Step 2 — Scope confirmation We confirm whether a detailed paid inspection is appropriate for your needs — pre-purchase, insurance, maintenance planning, or post-storm. We explain exactly what the report will include.
Step 3 — Full inspection with thermal imaging Our certified inspector conducts the complete assessment — thermal imaging, drone measurement, and physical inspection of all components. Typically 1–2 hours for residential; longer for commercial depending on size.
Step 4 — Written report delivery You receive the complete inspection report — written findings, photos, thermal imaging data, lifespan estimate, and prioritized repair recommendations. Any follow-up repair quote is provided free of charge with the report.
Step 5 — Questions answered We walk through the report with you, answer every question, and give honest advice on what needs attention and what can wait. No pressure to proceed with any repair.
Is your initial site visit really free? Yes — completely free, no obligation. We visit, assess the general condition, answer your questions, and give you an honest overview. The detailed paid inspection report is a separate service for when you need documented findings.
What does the paid inspection report include? Written condition report, photo documentation of every issue found, thermal imaging data, remaining lifespan estimate, and prioritized repair recommendations. If any repair or replacement is needed, the follow-up quote is provided free.
How long does a roof inspection take? Most residential inspections take 1–2 hours. Commercial properties vary by roof size and system type. We confirm the expected time when scheduling.
How often should I have my roof inspected? Annually is ideal for older roofs and commercial properties. Every 2–3 years is appropriate for newer residential roofs in good condition. Always inspect after a significant storm event.
Can the inspection report be used for a real estate transaction? Yes. Our written reports with photos and thermal imaging findings are accepted by real estate professionals, lawyers, and insurance carriers throughout Ontario.
Do you inspect commercial buildings? Yes — flat and low-slope membrane systems (TPO, EPDM, modified bitumen, BUR), commercial metal systems, and all associated penetrations, drainage, and flashing. We service commercial properties of all sizes.
What is thermal imaging and why does it matter? Thermal cameras detect temperature differences caused by trapped moisture and wet insulation beneath the roof surface — revealing entry points and existing moisture damage that no visual inspection can find. It’s the most accurate leak-source diagnostic available.
What is included in a custom maintenance plan? Every plan is built to the property — scheduled inspections, drainage maintenance, flashing checks, post-storm visits, and priority repair scheduling. We discuss your property’s specific needs and build a plan accordingly.
Can you inspect a roof I didn’t install? Yes. We inspect roofs regardless of who installed them or when. Our assessment is independent and honest.
