Why does my roofer have to show me his ten-year before work?

With regard to the rules of construction practice, the roof is an inseparable element of the house which contributes to its integrity. It is therefore covered by the ten-year guarantee. The insurance presented by your roofer will protect you in the event of a defect or poor workmanship on this work.

Why require it before the works?

It is the law that lays down the guidelines, the craftsmen must produce this document, from the moment they draw up an estimate. Since July 2016, a certificate of subscription to a ten-year guarantee must naturally accompany quotes and invoices. Through this document, your roofer must communicate a minimum of information, as the specialist Ladecennale.fr reminds us. Among other things, it should include the references of the contract as well as the identity of the insurer and the craftsman, as insured.

Also note that this part specifies the elements relating to the scope of the warranty. This concerns aspects as varied as the techniques used or the geographical area. Be careful and check, in your case, that the professional activity covered by the guarantee is that of the roofer. You must therefore be in possession of this proof as soon as the work begins. After the work and in the event that you sell your property within 10 years, the buyer must also have this certificate.

When to implement the ten-year roof guarantee?

If you notice defects in the installation or design of your roof, you can claim the terms of the ten-year guarantee provided by your roofer. This is also the case if you notice irregularities concerning the materials used for the realization of the work. Thus, the observation of condensation problems inherent in the construction of a cold flat roof can make you resort to the ten-year guarantees.

The same applies if poor rainwater drainage is due to inappropriate fixing of the insulation panels of a warm flat roof. Poorly made joints, tears or cracks in coating materials like EPDM can spell disaster for your home. Do not hesitate to assert your rights in the presence of such defects.

What to do in the presence of a defect on the work of a roofer?

The construction or renovation work carried out by your roofer dates back less than 10 years and you notice an anomaly in the work? React in accordance with your situation in relation to the property damage insurance. If you do not benefit from it, you have 2 maneuvers, to alternate in order. Write and send a registered letter to your craftsman, instructing him to carry out the repairs, according to the terms of the guarantee. Photos and details demonstrating the ten-year nature of the damage must be attached to this letter. Depending on the case, the roofer will carry out the repairs without declaring a claim or will seize his insurer. If he does not respond to your formal notice, contact his ten-year insurer directly. In doing so, you invoke the Insurance Code in its article L124-3, by constituting yourself as an injured third party.
