Why choose an RGE-certified roofing company in Paris?

What is RGE certification?

RGE certification (Reconnu Garant de l'Environnement — Recognised Environmental Guarantor) is a quality label awarded by accredited certification bodies (Qualibat, Qualifelec, Cerqual...) that attests a construction company has the technical skills required to carry out energy renovation works in compliance with current standards, and which conditions access to French state grants for homeowners.

Since its launch in 2011, the RGE label has become essential in the energy renovation sector. In Paris and Île-de-France, where thousands of older buildings need renovation, choosing an RGE-certified company is not just a quality guarantee — it is a legal prerequisite to access financial aid that can cover up to 75% of insulation work costs.

Who issues RGE certification?

RGE is not a single label — several certifications are recognised under the RGE scheme, issued by different bodies depending on the type of work.

For roofing and roof insulation: Qualibat is the most common certifier. To obtain Qualibat RGE certification, a company must:

1. Ensure employees carry out qualifying energy performance training (Feebat programme or equivalent)
2. Have at least one worksite audited by an independent Qualibat inspector
3. Maintain skills through compulsory continuing education every 4 years
4. Renew certification every 4 years with a worksite inspection

How to verify a company's RGE certification: Visit faire.fr (official ADEME directory), enter the company name or SIRET number, and check the certification domains and validity date.

Why is RGE certification mandatory for grants?

Since France's 2014 Energy Transition laws, using an RGE-certified company is a legal requirement for all state grants:

• MaPrimeRénov' (ANAH): 100% of eligible works require an RGE contractor
• CEE (Energy Savings Certificates): RGE mandatory
• Eco-PTZ (zero-interest loan): RGE mandatory

The potential savings: For 80 m² of loft insulation in Paris, grants for a low-income household can reach:

• MaPrimeRénov': up to €2,000
• CEE: up to €1,500
• Total grants: up to €3,500 on a project costing €5,000–8,000

Without an RGE contractor, all these grants are lost. The apparent premium of an RGE company is far outweighed by the grants it enables you to access.

Quality guarantees provided by RGE certification

Up-to-date technical training

RGE company employees have completed specific training on building energy performance and insulation techniques compliant with current standards. These are regularly updated.

In practice this means: real knowledge of insulating materials and their actual thermal performance (R-value), mastery of ventilation rules (thermal bridges, moisture management), ability to select the right materials for each situation.

Independent worksite audit

To obtain and maintain certification, each RGE company must have its worksites audited by an independent Qualibat inspector, who verifies: the conformity and performance of installed materials, workmanship quality, and compliance with best practices.

Relevant Qualibat qualifications for roofing

• 3111: Tile and slate roofing
• 3112: Zinc, lead and copper roofing
• 3121: Roof waterproofing
• 4111: Loft insulation

Verify that the company holds qualifications matching the specific works you need.

Insurance advantages of RGE certification

RGE-certified companies typically hold decennial liability insurance (garantie décennale) specifically covering energy performance works. They benefit from better insurance terms due to fewer claims among certified companies.

If you use a non-certified company and problems arise: the company may have no valid decennial insurance, leaving you without recourse; your own damage insurance may refuse to cover defects if the contractor lacked required RGE certification.
