Location: Scarborough, Ontario
Roof Type: Modified Bitumen Roof
Project Scope: Restoration of a 15-year-old modified bitumen roof membrane, including roof scanning, membrane repairs, perimeter and curb flashing replacement, a new cold adhesive flood coat with embedded pea stone gravel, full-coverage sheet metal flashings, and a new paver walkway for HVAC access.

PROJECT OVERVIEW

Industrial Roofing Services Limited was brought in to restore a 15-year-old modified bitumen roof in Scarborough. Rather than replacing the existing membrane, the goal was to restore the roof and address the deficiencies that had developed over its service life, with the project designed to provide the client with another 15 years of useful roof life.

The first step was to scan the roof to confirm that no saturation was present within the existing assembly. With the roof confirmed to be suitable for refurbishment, our team proceeded with fixing the flat roof’s deficiencies identified throughout the roof field.

Once the membrane repairs were completed, attention shifted to the areas most critical to maintaining a watertight roof: the perimeter and curb flashings. These details were redone before the roof field received a new cold adhesive flood coat with 3/8-inch pea stone gravel embedded into it. New full-coverage sheet metal flashings were also installed at the perimeter walls and curb flashings, completing the restoration of the roof’s protective details.

WORK COMPLETED

Our crew completed the roof refurbishment, which included:

• Scanning the existing roof to confirm that no saturation was present
• Repairing deficiencies identified throughout the roof field
• Redoing the perimeter flashing details
• Redoing the curb flashings to improve waterproofing at these areas
• Applying a new cold adhesive flood coat across the roof field
• Embedding new 3/8-inch pea stone gravel into the flood coat
• Installing new full-coverage sheet metal flashings at the perimeter walls
• Installing new full-coverage sheet metal at the curb flashings
• Installing a new paver walkway to improve access to the HVAC units for maintenance technicians

New Roofing System Installed

• Existing Membrane Restoration: The 15-year-old modified bitumen membrane was retained and restored rather than replaced. A roof scan was completed first to confirm that no saturation was present before refurbishment work began.
• Roof Field Treatment: After the identified membrane deficiencies were repaired, a new cold adhesive flood coat was installed throughout the roof field. New 3/8-inch pea stone gravel was then embedded into the coating.
• Perimeter & Curb Flashings: The perimeter and curb flashing details were redone to address these critical waterproofing areas. New full-coverage sheet metal flashings were installed at the perimeter walls and curb flashings.
• HVAC Access: A new paver walkway was installed to provide a defined path to the HVAC units, making access easier for technicians carrying out maintenance.

Project Challenges & Solutions

1. Determining Whether the Existing Roof Could Be Restored

Before proceeding with refurbishment, it was important to confirm the condition of the existing roof assembly. Our team scanned the roof to verify that no saturation was present. With the scan confirming the absence of saturation, the existing 15-year-old modified bitumen membrane could be restored rather than replaced.

2. Addressing Aging Perimeter and Curb Details

The roof field was not the only area requiring attention. The perimeter and curb flashings also needed to be redone to establish tight waterproofing at these details. New full-coverage sheet metal flashings were subsequently installed at the perimeter walls and curb flashings as part of the refurbishment.

PROJECT OUTCOME

The Scarborough project allowed Industrial Roofing Services Limited to restore a 15-year-old modified bitumen roof rather than replacing the existing membrane. After confirming that no saturation was present, our team repaired the deficiencies throughout the roof field and rebuilt the perimeter and curb flashing details before applying the new cold adhesive flood coat and pea stone gravel.

The completed refurbishment was designed to provide the client with another 15 years of roof life. The project also included new full-coverage sheet metal flashings and a paver walkway to the HVAC units, giving maintenance technicians easier access while completing future HVAC work.

Location: Markham, Ontario
Roof Type: Inverted Flat Roof and Sloped Metal Roof
Project Scope: Replacement of an existing inverted 4-ply built-up roof with a new 2-ply SBS modified bitumen system while retaining the existing ballast, along with cleaning, priming, repairing, and coating the building’s aging sloped metal roof.

PROJECT OVERVIEW

A new client in Markham contacted Industrial Roofing Services Limited with two separate roofing concerns at their building. The existing inverted flat roof had developed several ongoing leaks, while the sloped metal roof was also approaching the end of its service life and needed to be refurbished.

Rather than replacing both roofing systems outright, we worked with the client to develop an approach that addressed the problems with the inverted roof while allowing the existing river rock ballast to be retained and reused. At the same time, the sloped metal roof could be cleaned, repaired, primed, and recoated to give the aging surface a new finish.

The flat roof work focused on replacing the existing inverted 4-ply built-up roof with a new 2-ply SBS modified bitumen roofing system, providing the building with a completely renewed flat roof replacement. The sloped metal roof was then refurbished with a new jet black thermoplastic rubber coating. The client also chose to update the building’s appearance by replacing the perimeter sheet metal flashing with a jet black finish to complement the newly coated metal roof.

WORK COMPLETED

Our crew completed the flat and sloped roofing work, which included:

• Removing the existing inverted 4-ply built-up roof system
• Rebuilding the perimeter detail and installing new 2-ply SBS modified bitumen flashings
• Installing the new 2-ply SBS modified bitumen roof membrane
• Installing a separation sheet over the new membrane
• Installing new 2-inch XPS insulation
• Installing a new Fabrene fabric layer over the insulation
• Reusing the existing river rock ballast over the completed inverted roof assembly
• Replacing the perimeter sheet metal flashing with a jet black finish
• Cleaning and preparing the existing sloped metal roof surface
• Repairing fastener holes in the metal roofing
• Priming the prepared metal using the manufacturer-specified product
• Applying a new jet black thermoplastic rubber coating to the sloped metal roof

New Roofing System Installed

• Flat Roof Membrane: The existing inverted 4-ply built-up roof was replaced with a new 2-ply SBS modified bitumen roofing system. New SBS modified bitumen flashings were also installed as part of the rebuilt perimeter detail.
• Inverted Roof Assembly: Following membrane installation, a separation sheet was placed over the new roof system, followed by new 2-inch XPS insulation. A new Fabrene fabric layer was then installed before the existing river rock ballast was returned to the roof.
• Sloped Metal Roof Coating: The existing metal roofing was thoroughly cleaned and prepared before fastener holes were repaired. The prepared surface was primed with a manufacturer-specified product and finished with a new jet black thermoplastic rubber coating.
• Perimeter Sheet Metal: The existing perimeter sheet metal flashing was replaced with new jet black flashing, giving the building a consistent finish between the flat roof perimeter and the newly coated sloped metal roof.

Project Challenges & Solutions

1. Replacing the Leaking Inverted Roof While Retaining the Existing Ballast

The building’s inverted roof had several ongoing leaks and required replacement, but the existing river rock ballast was still available for reuse. The new roof assembly was therefore completed in stages, with the new 2-ply SBS modified bitumen system installed first, followed by the separation sheet, 2-inch XPS insulation, and Fabrene fabric layer. The existing ballast was then reused over the completed assembly rather than replaced.

2. Refurbishing an Aging Sloped Metal Roof

The sloped metal roof was nearing the end of its service life and required more than simply applying a new coating over the existing surface. Our crew first cleaned and prepared the metal, repaired the fastener holes, and applied the manufacturer-specified primer. Once the surface was properly prepared, the new jet black thermoplastic rubber coating was installed.

PROJECT OUTCOME

The project addressed both of the building’s roofing concerns with a combination of replacement and refurbishment. The leaking inverted 4-ply built-up roof was replaced with a new 2-ply SBS modified bitumen system and rebuilt perimeter detail, while the existing river rock ballast was retained and reused as planned. The sloped metal roof was also refurbished with a new coating, completing a major upgrade to the building’s commercial roofing system.

The sloped metal roof received a complete surface preparation, fastener repairs, manufacturer-specified primer, and new jet black thermoplastic rubber coating. Along with the new jet black perimeter sheet metal flashing, the work gave the building a significantly refreshed appearance while addressing the aging condition of both roofing systems.

Location: Toronto, Ontario
Roof Type: Low-Slope Residential Roof
Project Scope: Complete removal of a failing modified bitumen membrane and defective top coating, followed by the installation of new coverboard insulation and a fully adhered 60 mil Carlisle TPO roofing system.

PROJECT OVERVIEW

Industrial Roofing Services Limited was contacted by a homeowner experiencing severe water intrusion, with active leaks running down their interior walls. Upon a thorough inspection, our team identified that the home’s aged modified bitumen roof was actively peeling up and failing along the perimeter. We also discovered that a previous contractor had attempted to resolve the issue by applying a surface coating over the membrane. Unfortunately, this temporary fix was also failing, allowing water to bypass the system and cause significant interior damage.

To permanently stop the leaks and protect the home’s interior framing and drywall, our team determined that patching the roof was no longer a viable option. A complete tear-off down to the structural wood deck and fully replacing the roof system was required to restore the home’s watertight integrity.

WORK COMPLETED

Our residential crews executed a complete roof replacement, which included:

• Complete tear-off of the aged modified bitumen membrane and the failed surface coating down to the bare wood deck
• Thorough cleaning and preparation of the exposed structural decking
• Installation of new coverboard insulation to create a rigid, uniform substrate
• Application of a fully adhered 60 mil Carlisle TPO membrane
• Securing all perimeter edge details to prevent future peeling or wind uplift

New Roofing System Installed

• Substrate Preparation: High-quality coverboard insulation was installed directly over the wood deck. This provides a clean, smooth, and durable foundation that enhances the performance and puncture resistance of the new membrane.
• Membrane System: 60 mil Carlisle TPO (Thermoplastic Polyolefin). Rather than mechanically attaching the membrane, we utilized a fully adhered application method. This makes sure the TPO is bonded completely to the coverboard, offering superior wind resistance, a seamless aesthetic, and highly reliable waterproofing for residential low-slope roofs.

Project Challenges & Solutions

1. Rectifying Failed Previous Repairs

The combination of a peeling perimeter and a defective top coating meant the old roof had entirely lost its structural integrity. Applying another layer of coating would not have stopped the severe wall leaks. By stripping the roof down to the original wood deck, we eliminated the flawed materials entirely, ensuring our new TPO system had a flawless foundation to adhere to.

2. Racing Against the 2026 Winter Season

With water already infiltrating the home’s interior walls, time was a critical factor. Leaving the roof exposed to freezing temperatures, ice accumulation, and snow loads would have resulted in catastrophic interior damage. Our team prioritized this project’s scheduling to make sure the full tear-off and installation were completed efficiently, making the home 100% watertight before the harsh 2026 winter weather arrived.

PROJECT OUTCOME

By removing the deeply compromised modified bitumen roof and addressing the root cause of the perimeter failures, Industrial Roofing Services Limited successfully stopped the severe interior wall leaks. The transition to a modern, fully adhered 60 mil Carlisle TPO membrane provides the homeowner with a highly durable, weather-resistant barrier.

The project was completed on schedule, granting the client total peace of mind. They now have a clean, professionally installed roofing system that will keep their home safe, dry, and protected through the 2026 winter and for many years to come.

Location: Woodbridge, Ontario
Roof Type: Sloped Shingle Roof
Project Scope: Complete removal of failing 3-tab shingles, correction of underlying moisture-barrier deficiencies, installation of a new architectural shingle system with custom metal details, and full site remediation.

PROJECT OVERVIEW

Industrial Roofing Services Limited was selected to fully replace a sloped roof for a large retirement facility in Woodbridge. The building’s existing 3-tab shingles had become extremely aged and brittle, offering very little defense against harsh weather conditions.

During the initial tear-off phase, our crews uncovered a significant vulnerability: the original roofing system had been installed without any underlayment or ice and water shield. This meant the bare wood decking was highly susceptible to rot and moisture intrusion. Our objective was not only to replace the failing shingles but to completely rebuild the roof’s waterproofing foundation to guarantee the safety and comfort of the facility’s residents.

WORK COMPLETED

Our team executed a comprehensive roof replacement, which included:

• Complete tear-off and removal of the brittle, aged 3-tab shingles
• Thorough inspection of the exposed wood deck to guarantee structural integrity
• Installation of a double layer (2 layers) of ice and water shield at all eaves and valleys
• Application of new underlayment across the entire roof decking
• Installation of new metal valleys and perimeter drip edges
• Supply and installation of premium architectural shingles
• Comprehensive post-project cleaning of all eavestroughs and downpipes
• Strict site cleanup to remove all construction debris from the facility grounds

New Roofing System Installed

• Primary Moisture Barrier: To correct the flaws of the original roof, we applied a new layer of underlayment across the entirety of the wood decking, creating a vital barrier against wind-driven rain.
• Reinforced Ice Protection: We installed two continuous layers of ice and water shield at the eaves and inside the roof valleys, the areas most prone to winter ice damming and heavy water flow.
• Architectural Shingles: The building was upgraded to a modern architectural shingle, providing superior thickness, enhanced wind resistance, and a much longer lifespan than the previous 3-tab system.
• Custom Metal Flashings: New metal valleys and drip edges were installed to actively direct water away from the fascia and efficiently channel it into the gutter system.

Project Challenges & Solutions

1. Correcting Hidden Installation Deficiencies

Discovering that the original roof lacked basic underlayment and ice protection required an immediate pivot in focus to structural defense. By thoroughly inspecting the bare wood deck and installing a robust, multi-layer waterproofing foundation, we effectively eliminated a hidden risk that had been threatening the building for years.

2. Prioritizing Resident Safety and Site Cleanliness

Working at an active retirement home requires an elevated level of care, respect, and site management. Protecting the residents and staff was our top priority. We made sure that all work zones were kept organized and that the property was left spotless upon completion. As an added measure of service, our crews meticulously cleaned out all eavestroughs and downpipes to guarantee the new roof system would drain perfectly, leaving zero construction debris behind.

PROJECT OUTCOME

The retirement home is now protected by a fully modernized architectural roofing system. By addressing the critical lack of underlayment and installing double-layered ice protection, Industrial Roofing Services Limited corrected a major structural vulnerability.

The transition from brittle, outdated shingles to a fortified architectural assembly provides the property management team with long-term peace of mind. The facility now boasts a beautiful, highly durable roof that will keep its residents safe, dry, and comfortable for decades to come.

Location: Woodbridge, Ontario
Project Size: 140,000 Square Feet
Project Scope: Large-scale membrane replacement utilizing an infrared moisture scan for targeted insulation removal, complete facility-wide insulation overlay for improved R-value, and installation of a mechanically attached 60 mil Carlisle TPO single-ply roofing system.

PROJECT OVERVIEW

Industrial Roofing Services Limited was brought in to address an aging and failing built-up roof (BUR) membrane on a massive 140,000-square-foot manufacturing facility in Woodbridge. When dealing with a roof of this magnitude, a full tear-off down to the structural deck can be incredibly costly and disruptive.

To determine the most efficient and budget-friendly approach for our client, our team initiated the project by conducting a comprehensive infrared moisture scan of the entire roof surface. The scan revealed that the overall quantity of saturated insulation was relatively low. This critical data allowed us to pivot from a full tear-off to a strategic replacing of the roof. By saving the dry, viable insulation and only removing the compromised materials, we were able to deliver a modern, energy-efficient roofing upgrade while providing significant cost savings for the facility’s ownership.

WORK COMPLETED

Our crew executed a precise and large-scale membrane replacement, which included:

• Conducting an initial infrared scan to map out localized areas of wet insulation
• Vacuuming and extracting all existing pea gravel from the roof surface
• Completely removing the failing 4-ply built-up roof membrane
• Excavating and responsibly disposing of the targeted wet insulation identified in the scan
• Installing replacement insulation in the excavated areas to level the system
• Installing a brand new layer of insulation across the entire facility to boost thermal performance
• Mechanically attaching a new 60 mil Carlisle TPO single-ply membrane
• Precision heat-welding all membrane seams to create a unified, watertight barrier

New Roofing System Installed

• Diagnostic Technology: Thermal infrared scanning was utilized prior to construction to scientifically verify the condition of the underlying assembly, preventing unnecessary waste.
• Insulation Upgrade: In addition to replacing the compromised sections, a continuous new layer of insulation was installed, significantly improving the building’s overall R-value and reducing long-term heating and cooling costs.
• Membrane System: 60 mil Carlisle TPO (Thermoplastic Polyolefin). This high-performance single-ply membrane is highly reflective, exceptionally durable, and specifically well-suited for low-traffic roof areas.
• Seam Integration: The TPO membrane was mechanically attached to the deck and all seams were heat-welded, fusing the material together to form an impenetrable shield against water infiltration.

Project Challenges & Solutions

1. Heavy Material Removal at Scale

Before the new system could be installed, years of existing pea gravel needed to be removed from the sprawling roof. We utilized specialized industrial vacuum equipment to efficiently clear the stone from the roof surface, keeping the site clean and preparing a smooth substrate for the membrane replacement without halting the manufacturing work happening inside the building.

PROJECT OUTCOME

By combining advanced diagnostic technology with expert installation, Industrial Roofing Services Limited successfully transformed a failing BUR system into a highly efficient, watertight asset. The decision to perform a membrane replacement rather than a complete tear-off resulted in substantial cost savings for the client while still delivering a massive upgrade in thermal performance (R-value).

The new 60 mil Carlisle TPO system offers a clean, reflective, and low-maintenance finish that is perfectly tailored to the low-traffic demands of the facility. Thanks to it’s brand new flat roof, the manufacturing plant is now fully protected by a modern single-ply system designed to deliver long-term reliability and energy efficiency.
