The warranty of your residential or commercial roofing system covers manufacturer defects and faulty installation. This means that if your contractor uses damaged materials or installs a certain component incorrectly, your warranty will cover the costs to correct the problem. Moreover, it always pays to invest in roofing products with comprehensive warranties. 

Read on to find out the common causes of a voided roofing warranty. 

Using Mismatched Components

Your warranty will likely become invalid when your roofer uses components from different manufacturers. This practice can also compromise the structural integrity of your roof. Your roofing contractor must use matching system components and adhere to the manufacturer’s installation requirements. 

Installing New Shingles Over the Old Roof

A reputable roofing contractor will not recommend installing new shingles over the old ones just so you can save on costs. However, some roofers offer this option to attract customers due to its lower cost. Keep in mind that layering shingles will not only void your warranty but also reduce the life of the shingles and damage the structure of your roof. A complete tear-off remains the best roof replacement option. 

Insufficient Ventilation

Another thing that can void your warranty is poor attic ventilation. Sufficient ventilation is crucial to the longevity and stability of your roof. It can also contribute to warping of the roof deck, early roof deterioration and mold and mildew growth. This is another reason you should hire a skilled roofing contractor for your project. A good roofer will make sure that your roof is properly vented to prevent costly moisture-related issues.
