We hired 431 Roofing to re-roof our house in Winnipeg. 431 Roofing was able to start the job soon and the completed the work in the timeline as promised. We were worried about all our flowers and our garden and they were very careful to make sure nothing was damaged we were happy and impressed with this. They installed metal valley's which none of the other companies quoted on as this is where we had most of the wear in our previous shingles. My wife and I are very pleased and would not hesitate to recommend 431 Roofing to anyone who requires their services.

Winnipeg/West St Paul area. Our shingles were in dire need of replacing as we had put it off for a few years. We were very happy with 431 Roofing's services. James was great to deal with to the point he even came out a few days prior to the roof being done in order to patch three spots because we had a severe thunderstorm coming later that day. All workers were professional, completed the job within the estimated time frame and cleaned everything afterwards. Definitely recommend!

We were very satisfied with 431 Roofing. James responded very quickly, was out to give us a quote within a day and was able to have his crew start our roof within one week. Once our old shingles were removed, it was evident our decking was rotten and needed to be replaced. James took photos of the roof and showed us the rotted wood which had several holes in it. A new quote was given and decking was ordered. The work was done in a reasonable time line, the area was cleaned thoroughly afterward and we think the roof looks great. We were happy with both the quality and value of the work 431 roofing did.

We are very glad we chose to work with 431 roofing! They did an amazing job re-shingling our home here in Winnipeg. They were quick to respond to our inquiries and gave us a competitive quote. When our roof started leaking they came the SAME day to patch our roof to prevent further water damage. The following week they began the actual re roofing work. Their workmanship is top notch and they worked very quickly. We have referred several friends to 431 Roofing. We plan to use them for soffit and eavestroughs work in the future.

Potential for Recurring Issues

Repairs might not resolve the root cause of the problem, leading to recurring issues that require ongoing maintenance and additional expenses over time.

Questions About Flat Roofing? We Have Answers!

What Is Flat Roofing?

Flat roofing is a type of roofing system characterized by a nearly horizontal or low-slope design. It is commonly used in commercial buildings, industrial facilities, and some residential properties. Flat roofs are known for their accessibility, ease of maintenance, and the potential for additional usable space, such as rooftop gardens or terraces.

What Areas Do You Provide Your Flat Roofing Service To?

We service all of Winnipeg, Manitoba, and its surrounding areas. Our team has completed flat roofing projects in various rural indigenous reserve communities and as far as West Hawk Lake, ensuring quality service wherever we go!

Why Do Flat Roofs Need Replacement or Repair?

Flat roofs endure significant stress from environmental factors such as wind, snow, and rain. Over time, these elements can cause considerable damage. Here are some common reasons flat roofs need replacement or repair:

  1. Ponding Water: Flat roofs are prone to water accumulation, which can lead to leaks and structural damage if not properly drained.
  2. Membrane Damage: The roofing membrane can become damaged due to weather, debris, or foot traffic.
  3. Aging: Most flat roofs have a lifespan of 15-25 years. If your flat roof is older than that, it’s likely time for a replacement.
  4. Leaks: Persistent leaks can cause water damage to your building’s interior, necessitating repairs or a new roof.
  5. Thermal Expansion: Temperature fluctuations can cause the roofing material to expand and contract, leading to cracks and splits.

Do You Do Residential Flat Roofing?

Absolutely, we provide top-quality residential flat roofing services in Winnipeg. Our team is dedicated to ensuring that your home is protected and looks its best. From initial inspection to the final installation, we handle every aspect of the flat roofing process with care and professionalism.

Do You Do Commercial Flat Roofing?

Yes, we specialize in commercial flat roofing in Winnipeg. Our team understands the unique challenges that come with commercial roofing projects, from larger surface areas to specific material requirements. Whether you own a small business or a large industrial complex, we have the expertise to handle any commercial flat roofing project.

Average Cost of Flat Roofing in Winnipeg

The cost of flat roofing in Winnipeg varies based on several factors, including the size of the project, the type of materials used, and the complexity of the installation.

For smaller projects, you are generally looking at $2,000 to $6,000.

On average, for larger projects, you can expect to pay between $6,000 and $12,000. Premium materials and more complex installations can cost more, ranging from $10,000 to $25,000 or more.

When Should I Choose Flat Roofing?

Flat roofing can be a practical and cost-effective solution for certain types of buildings. Here are the key factors to consider when deciding if flat roofing is the right choice:

Building Type: Flat roofs are ideal for commercial, industrial, and some residential buildings.

Usable Space: If you need additional space for HVAC units, solar panels, or a rooftop garden, flat roofing is a suitable option.

Accessibility: Flat roofs are easier to access for maintenance and repairs compared to pitched roofs.

Cost Considerations: Flat roofing is generally more affordable to install and maintain than pitched roofing.

When to Avoid Flat Roofing

Heavy Snowfall Areas: Flat roofs can be problematic in regions with heavy snowfall due to potential water accumulation and added weight.

Poor Drainage: If your property has inadequate drainage systems, a flat roof may not be the best choice as it can lead to water pooling and damage.

High Foot Traffic: While flat roofs can accommodate some foot traffic, excessive use can lead to membrane wear and damage.

The Flat Roofing Process

Understanding the flat roofing process can help you prepare for the project. Here’s a step-by-step breakdown:

Inspection: A thorough inspection will identify the extent of damage and the scope of work required.

Preparation: The old roofing materials are inspected and any damaged areas are repaired.

Installation of New Roofing System: New flat roofing materials, such as TPO, EPDM, or modified bitumen, are installed according to manufacturer specifications.

Flashing and Sealing: Flashing and sealing are applied to vulnerable areas to prevent leaks.

Cleanup and Final Inspection: The site is cleaned up, and a final inspection ensures everything is up to standard.

Types of Flat Roofing Systems

There are several types of flat roofing systems to choose from, each with its own benefits:

TPO (Thermoplastic Olefin): Known for its energy efficiency and durability.

EPDM (Ethylene Propylene Diene Monomer): A durable synthetic rubber roofing membrane.

Modified Bitumen: Combines asphalt with modifiers to improve its performance.

PVC (Polyvinyl Chloride): Offers excellent durability and chemical resistance.

Commonly Replaced Flat Roofs in Winnipeg

In Winnipeg, flat roofs on commercial buildings, industrial facilities, and some residential properties are commonly replaced. These roofs are favored for their accessibility and potential for additional usable space.
