Manufacturers' warranties usually offer coverage when there is a defect in the roofing material that causes leaks under normal conditions. A manufacturer's coverage will typically cover the cost of replacing the materials, not the labor to do so. They also do not cover replacing the entire roof, just repairing or replacing the defective areas.
Manufacturers' warranties often exclude damage due to pre-existing conditions of the roof. If the shingles were installed improperly or the roof structure and gutter design was faulty, coverage may be denied. Many warranties are prorated, meaning the longer the roof is on your home the less coverage you have.
Manufacturers may recognize quality professionals that they trust. These contractors may be able to offer additional or extended manufacturers' warranties.
Be sure to understand the coverage and limitations of a manufacturer's warranty before using it to make your roofing decisions.
While a good warranty to cover defects is important, choosing your roofing contractor is as much so.
Manufacturers' warranties do not cover problems arising from installation. This is where a workmanship guarantee comes in.
A workmanship guarantee is offered by the contractor and covers all defects related to installation work only. A qualified contractor will know what type of material to use on your roof and how to install it properly, reducing the possibility of roof leakage. Your contractor will also recognize potential problems such as structure, drainage and ventilation issues and address those ahead of time so they won't damage your new shingles in the future. A reputable contractor will offer a labor warranty to cover any issues that may arise for additional peace of mind.
When considering your new roof investment, be sure to look at the coverage warranties offer and especially the quality and knowledge of the company installing them.
