Questions About Our Free Roof Assessment

Here, you will find answers to the most frequently asked questions about our commercial, industrial, and institutional roof inspection services.

Is a preventive maintenance program required to maintain the manufacturer’s warranty?2026-09-21T15:23:44-04:00

In many cases, yes. Many manufacturers require periodic roof inspections and maintenance to keep certain warranties fully valid. Requirements vary depending on the manufacturer and the roofing system installed. Keeping inspection reports, maintenance records, and proof of repairs is strongly recommended.

Do you offer customized preventive maintenance contracts for property managers?2026-09-21T15:23:12-04:00

Yes. At LK Toitures, we offer preventive maintenance programs tailored to the needs of property managers. Regular inspections and ongoing roof condition monitoring help identify problems early, extend the life of the roofing system, and reduce the risk of costly repairs.

What are the most common problems identified during a flat roof inspection?2026-09-21T15:14:45-04:00

The most common problems include:
Ponding water
Cracks or tears in the roofing membrane
Damaged or defective flashing
Open seams
Clogged drains
Deterioration around mechanical equipment
Damaged or deteriorated sealants
Moisture trapped in the insulation
We also use infrared thermography to assess roofing systems. This technology can detect certain anomalies and areas of moisture beneath the membrane, providing a more accurate picture of the roof’s overall condition.

How often should the roof of an industrial building be inspected?2026-09-21T15:12:16-04:00

Industry best practices generally recommend a professional roof inspection at least twice a year—once in the spring and once in the fall.
An additional inspection is also recommended after:
Strong winds
A major storm
Work performed on the roof by other trades
Any event that may have damaged the roofing membrane

What exactly does a commercial roof inspection involve?2026-09-21T14:57:22-04:00

A roof inspection provides a clear picture of the condition of your roofing system. The key components inspected include the membrane, metal flashing, and rooftop accessories.
The inspection helps identify your roof’s maintenance needs and supports effective budget planning. The Association des maîtres couvreurs du Québec (AMCQ) recommends having your roof inspected twice a year—once in the spring and once in the fall—to help maintain warranty compliance.

Is annual maintenance of a commercial flat roof really a priority?2026-09-21T14:56:56-04:00

Yes—from the very first year of the roofing system’s life. Annual maintenance helps you comply with warranty requirements and extend the lifespan of your roofing membrane.
Preventive maintenance is designed to identify and address issues and deterioration that may develop over time. Maintenance is performed following an inspection, which determines whether your roof requires minor or major repairs.
Ask your technician about our preventive maintenance plan. Our team can recommend a solution tailored to your needs and your building: 450-437-4118.

They chose LK Toitures

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.

Jean-Guy Arseneault – Boulart

We were very satisfied with your service and the work done. Your employees were very professional and friendly.

We had excellent communication, and the team on-site seemed very professional and conscientious. I still need to visit the site to inspect the completed work.

Thiéry Roy – CISSSLAU

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.
