Difference between warranty on materials and warranty on work:
The warranty on installation is different from the warranty on materials. These two guarantees are complementary and serve to protect the owners of asphalt shingle roofs:
Materials account for only 30% of the total cost of an asphalt shingle roof, with the largest costs being labor and pavement installation costs. Therefore, in the event of a claim from the manufacturer to enforce the warranty on materials, the reimbursement should not exceed 30% of the total cost of the roof. The warranty on the installation is valid for several years and is generally not degressive. On the other hand, the guarantee on materials is degressive and the 100% refund ceases well before the end of the warranty period offered. This means that even with these two guarantees, it is difficult to get a full refund of asphalt shingle roofing costs a few years after installation.
Explanation of limited lifetime guarantees
Manufacturers offer limited lifetime guarantees through roofers. This guarantee is called “limited” because its duration is modeled on the life expectancy of the material. So, if the lifetime of your asphalt shingle coating is estimated at 15 years, the limited lifetime warranty will be 15 years. One must be aware of this subtlety, because many homeowners mistakenly think that they will be covered throughout their lives.
This guarantee is regressive and is divided into several periods that offer different levels of protection. If the first period gives you a 100% guarantee on the value of asphalt shingles, this percentage will decrease over the following periods. There will be no guarantee, and therefore refund, after the estimated lifetime of the coating. Therefore, a few years after installation, the owner will have to put in his pocket in case of deficiency of materials, even if he has a guarantee.
Exclusions of guarantees
When you have a warranty on installation or materials, you should read the warranty exclusions that appear on the contract. Indeed, there are several cases in which your guarantees can not apply:
It is also important to know that the reimbursement services of manufacturers work much like the reimbursement services of insurance companies. Indeed, from the second claim, the manufacturers will be reluctant to pay you back.
