Choosing the Right Flat Roofing Material

Not all flat roofing systems are the same; the right choice depends on your building type, budget, and how long you want it to last.

EPDM (rubber membrane) — Most cost-effective option, typically lasts 20-25 years, easy to repair if punctured.
TPO — Reflective white surface that helps reduce cooling costs in summer, typically lasts 20-30 years, popular for commercial buildings.
PVC — Best resistance to chemicals and grease, often used for restaurants and industrial buildings, typically lasts 20-30 years.

We’ll walk you through which option makes the most sense for your specific property during your free inspection.

Commercial Flat Roofing in Oakville

Commercial properties can’t afford roofing downtime that disrupts business, whether it’s a retail storefront, office building, or warehouse. As part of our full range of Oakville roofing services, we schedule work around your operating hours wherever possible, and for larger properties, we can often complete sections in phases so parts of your building stay fully operational throughout the project.

We work with property managers, business owners, and landlords across a range of commercial spaces, including:

Retail and strip mall units
Office buildings and multi-tenant properties
Warehouses and industrial buildings
Restaurants and food service properties (where roof-mounted HVAC and exhaust systems need extra care)

All commercial installations come with a written workmanship warranty, and we provide documentation you can pass along to insurance providers or property management for your records.

Worried About Flat Roof Drainage?

It’s a fair question. Flat roofs don’t drain as quickly as pitched roofs, and poor drainage is the number one cause of premature flat roof failure. The good news is that this is almost always a result of incorrect slope or clogged drains during installation, not a flaw in flat roofing itself.

We build in a slight slope toward drains during every installation, and we check drain placement carefully so water moves off the roof instead of pooling. If you’re already dealing with a roof that holds water after rain, that’s usually fixable without a full replacement, worth getting it looked at before it becomes a bigger problem.

Signs Your Flat Roof Needs Attention

Water pooling that doesn’t drain within 48 hours
Bubbling or blistering on the membrane surface
Seams starting to separate or lift
Water stains on interior ceilings
Your roof is 15+ years old and hasn’t been inspected recently

Trusted Flat Roof Replacement Contractors

Above It All Roofing employs a crew of seasoned roofers who excel in flat roof installation and replacement. Our team has extensive experience with projects of all sizes, from small residential repairs to expansive commercial flat roofs, working with materials like EPDM, TPO, and PVC membranes. If your building also needs work beyond the roof itself, we handle eavestrough and soffit installation too, so your entire exterior stays protected. When you select Above It All Roofing, you can be confident we’ll provide excellent workmanship at a reasonable price, backed by a satisfaction guarantee on every project.

A well-installed flat roof typically lasts 15 to 25 years depending on the material, but ponding water, punctures, and seam separation can shorten that lifespan significantly if left unaddressed. We recommend a quick visual check twice a year, especially after heavy rain or snow, so small issues like a lifted seam or clogged drain don’t turn into a full leak.

 Trustindex verifies that the original source of the review is Google. We called Christian to asses an issue with roof shingles and venting on a 10 year old roof. He came on site the same day,  is very knowledgeable, punctual, and provided a very reasonable estimate within hours of our request. I am a Realtor, and I will definitely contact him for further roof related work or assessments.

 Trustindex verifies that the original source of the review is Google. When obtaining quotes for re-roofing my house, Above It All Roofing did stand out as a contractor trying to do it right.  Sure they were slightly more expensive - but is it clever to try to save a few dollars on a roof, as it is one of the most important parts of a home. Also, Above It All offered a complete Certainteed package (using all Certainteed underlayments etc.).  Certenteed shingles are about 20% more expensive but are 20% heavier with hopefully provide 20% thicker protection.
Above It All did try real hard to do a good job under very bad weather conditions (no short cuts) and did return a few times to complete tasks and to see to a complaint (which I feel bad about as it turned out not to be anything to do with their workmanship) - but they did follow up anyway.
Roof is still brand new but it did survive the Burlington deluge of 2024 (huge storm!) without a drip and the roof looks fantastic After deliberating for weeks we chose Landmark Pro in Pewter color and I am sure that the value of my house has increased by twice the amount of money I spent on the re-roofing.  (Previously we had BP 3 tab singles that looked a little drab and flat and shingles would just fly off the roof with any strong wind - I definitely do NOT recommend BP Shingles)
All in all, I am very satisfied with Above It All roofing and have no hesitation in recommending them.

 Trustindex verifies that the original source of the review is Google. So impressed with Above it All Roofing I thought I would post about it.  Kristian provided a very detailed and reasonable quote for repairing a section of flat roof on our century home.  He presented the solution to the problem, the cost, the warranty and all the requisite insurance.  I will be using them exclusively for any future needs.  Note, I contacted fifteen roof contractors and Above it all left the pack behind by any measure.

FAQs

What's the difference between EPDM, TPO, and PVC roofing?

EPDM is the most budget-friendly option, TPO reflects heat and helps lower cooling costs, and PVC offers the best resistance to grease and chemicals, making it common for restaurants. We’ll recommend the right fit based on your property during your free inspection.

How long does a flat roof last?

Most flat roofing systems last 15 to 25 years depending on the material and how well drainage is maintained. Homes and businesses closer to Lake Ontario tend to see slightly faster wear due to wind-driven rain and freeze-thaw cycling.

How much does flat roof replacement cost in Oakville?

Cost depends on roof size, material, and accessibility. Contact us for a free, no-obligation estimate specific to your property.

Can a flat roof be repaired instead of replaced?

Often, yes, issues like a lifted seam or a clogged drain can usually be repaired without a full replacement. We’ll always tell you honestly which option makes more sense.

Do you handle both residential and commercial flat roofs?

Yes, we work on flat roofs for homes as well as retail, office, and industrial properties across Oakville, including commercial spaces near the Oakville GO corridor.
