Toiture PROJEX : be informed right

When it comes time to make roofing decisions, too much research is better than not enough! The majority of bad experiences shared by customers could have been avoided with a few simple checks.

Because Toiture Projex values your peace of mind, we have prepared the following list of key points and conditions that should be met by any reliable and competent company.

Licences and accreditations

While this may seem insignificant, the customer, when hiring a contractor, becomes what is known in the industry as the "chief contractor". This means that the customer bears a large share of the responsibility for the work and might be found at fault if some verification procedures are not carried out or if complications arise at the work site.

The chief contractor is responsible for ensuring that the roofing contractor has the appropriate accreditations and licences required to perform the work. Making sure the work complies with the regulations is a major part of the chief contractor's responsibilities.

Some of these accreditations are as follows:
Quebec Business Number (NEQ)
If the contractor fails to fulfill its tax obligations with the government, the latter has the right to claim the outstanding tax amount from the chief contractor.
Régie du Bâtiment du Québec (RBQ)
Certificates from the RBQ confirm that the contractor has the qualifications required to perform the work.
Commission de la Construction du Québec (CCQ)
The mission of the CCQ is to make sure that work is carried out according to standards. If the CCQ assigns an inspector and the company is declared "not in good standing" (this being considered a criminal offence), it has every right to shut down a work site.
Office de la Protection du Consommateur/Quebec Consumer Protection Bureau
The Bureau helps consumers make informed decisions and governs consumer-merchant relations. Toiture Projex holds an itinerant merchant permit. Consequently, our customers are also protected in their agreement with us under the provincial jurisdiction of that organization.
It offers consumer protection in exchange for a bond that varies between $10,000 and $20,000, paid by the contractor when it registers with the organization.
It is important that your assets are protected in the event of damages. Toiture PROJEX holds a two million dollar civil liability policy with the A.M. Frederick Underwriting Management Ltd. insurance company.
Do not hesitate to ask for supporting documents, and make sure they are all still valid. Also ask for references from former customers who can attest to the company's work ethic and level of services.


Toiture PROJEX : written agreement

It is said that words once spoken fly away, words once written remain forever. Oral agreements are risky, so make sure you enter into a formal written agreement that clearly spells out each party's rights and obligations. Here are a few points you should consider:


Do not rely on price alone to make a decision. The lowest quote may prove to be the most costly, regardless of what is in writing!

The contractor is not always able to tell what lies beneath an existing roof. It has a history, and can therefore yield many unpleasant surprises! For example, when removing the old roof, we may find several layers of roofing (rather common with asphalt and gravel roofs), which puts additional weight on the structure of the building and will likely entail extra labour and materials. Another example is the possibility of finding mould on the decking, which may very well have to be replaced.


Make sure you choose the right roofing system - one that fulfills your personal needs as well as those of the building itself. The price will vary based on the durability and longevity of the system selected.


There are several factors that determine the cost of a roofing project, the main ones being:

  • Area of the roof: Some roofing systems require a certain number of square feet to be added to the area to be covered. Square footage is calculated by measuring the ground area as well as the "rises" or "parapets", i.e. walls that run along the perimeter of the building or separate a roof from an adjacent one. Depending on the system chosen (elastomeric membrane, for example), these surfaces must be included in the calculation or the waterproofing system will not be as effective as it should be.
  • Tapered insulation: Water accumulation (improper drainage) can cause problems that will likely lead to premature deterioration of the roofing system. To prevent such accumulation from occurring, we highly recommend that you have tapered insulation installed around roof drains.
  • Roof access and logistics: Delivery of materials and roof access are important points to consider. If the area is surrounded by electrical wires or the property is not easily accessed, it will make it more difficult to do the work. Administrative tasks must be dealt with before the work even starts, such as visiting the borough offices to ensure that our procedures are compliant with municipal regulations, purchasing a permit for occupation of a public thoroughfare, ensuring worksite safety and restricting access to the worksite before work begins, proper placement of the waste and refuse system, etc.
  • Choice of roofing system:

    Asphalt and gravel: This is a system that is quick and inexpensive to install. Unfortunately, the quality and flexibility of the materials are not what they used to be and this decreases the lifespan of this system.

    Elastomeric bitumen membrane roofing: Completely waterproof, elastomeric membrane roofing is a durable and environmentally-friendly option. A high-performance product that delivers excellent value for your money.

  • Mechanical , ventilation, and skylight components: The number and type of mechanical components on the roof affect price. For adequate air flow, ventilators must often be added or replaced by newer models.
