Re-roofing
designed to last

At LK Toitures, commercial roof renovation is much more than just replacing materials. It’s a strategic intervention designed to ensure waterproofing, durability, and energy efficiency for high-value buildings. Thanks to our specialized expertise, we work on complex, large-scale roofs while addressing the specific needs of commercial and industrial buildings.

Our approach: beyond roof renovation

Before any work begins, our team conducts a thorough analysis of the roof and related building components. This assessment allows us to offer tailored solutions that match the existing structure, the building’s purpose, and its exposure to weather conditions.

Our roof renovation services include:

Demolition of existing structures
Safe removal of obsolete materials or elements prior to reconstruction. A key step in building a solid foundation for the future.

Complete waterproofing renovation
Application of high-performance waterproofing systems (elastomeric membrane, TPO, etc.) tailored to climate conditions and building usage.

Concrete repair and load-bearing structures
Rehabilitation of slabs, beams and other structural components to ensure roof stability and durability.

Installation and refurbishment of skylights
Updating or replacement of skylights to ensure better insulation, watertightness and optimal lighting.

Integrated mechanical and electrical work
Moving, modifying or replacing mechanical units, conduits, wiring and other technical elements during refurbishment.

Wall cladding and repair of vertical facings
Modernization or restoration of facades adjacent to the roof to create a homogeneous, high-performance envelope.

Earthworks, landscaping and excavation
Management of access, drainage or greening around the building as part of wider roof-related work.

Joinery and finishes
Integration of structural elements, framing, soffits or other architectural details required for a neat finish.

Waterproofing and coating of terraces
Specialized work on roof terraces, including membranes, slabs, railings and finishes, particularly for condominium projects.


Each project is overseen by a dedicated project manager who ensures smooth coordination throughout every phase of the worksite.

Very satisfied with the work done and the service. Your team was friendly, efficient, and professional, with great attention to quality workmanship. No water leaks have been noticed since the initial repairs.

Justin Hugues-Deraiche – Into Inc

The service was impeccable! Nothing to complain about, my technician had only positive feedback about the service team on-site.

Xavier Sylvain-Salvador – Ingétec

As far as I’m concerned… Quote, appointment, and report after the visit: A-1. Scheduling the work appointment – A-1. As for the day of the work, I received no feedback, so I presume it’s also A-1… If there are any comments, I will let you know. Invoice and report, A-1. Keep it up! (Note: getting your quote report so quickly after Dany’s visit is really awesome!)

Richard Bertrand - Daniel Abergel

A1 service. I haven’t received the service report. I saw the team when they arrived but not when they left.

Big thanks again for the great work! I really appreciated working with your company. This certainly won’t be the last time we get in touch.

Vincent Sabbagt

Thank you for your intervention. The work was well done, and the site and parking area were clean as well. I really appreciate it, especially since we had to ask the neighbor for permission to use their parking space. Communication was good, as were customer service and work quality—everything was excellent.
