Investing in a GAF roofing system can bring peace of mind thanks to the strength of their warranties, but it’s easy to accidentally void that valuable coverage. It is crucial to understand the major pitfalls homeowners in Iowa face, especially with fluctuating weather and the requirements of professional roofing installation. Here are the top items that can put your GAF warranty at risk and how to avoid them.
1. Unapproved Roof Modifications
Making unauthorized changes to your roofing system will often void your manufacturer’s warranty. Examples include installing satellite dishes, solar panels, or skylights without abiding by GAF’s approved installation procedures. Unauthorized roof penetrations can cause leaks, and any water intrusion will not be covered. Instead, always consult a professional with experience in roof repair, and make sure modifications are documented and approved.
2. Improper Installation by Non-GAF Certified Contractors
GAF requires that its roofing systems be installed by certified contractors. If you opt for a low-cost, non-certified installer, you risk shingle failures, poor ventilation, or incorrect underlayment, all of which can negate your warranty. Using a GAF Master Elite or Certified installer, such as Evans Roofing Home Repair, Inc., ensures that your roof replacement meets warranty standards and is built to withstand the variable Iowa weather.
3. Inadequate Ventilation and Insulation
Failing to provide proper attic ventilation and insulation can result in excess heat and moisture build-up, leading to premature shingle wear. This is a common issue in the Midwest, where seasonal temperature swings are normal. When attics overheat or gather condensation, not only do shingles age prematurely, but the issues are deemed installation-related, thus disqualifying the warranty coverage. Always request an inspection of ventilation when scheduling routine maintenance or roof inspection.
4. Pressure Washing or Using Harsh Cleaning Methods
Some homeowners in rural Iowa use pressure washers to clean their roofs of algae or debris. Unfortunately, pressure washing can remove protective granules from shingles, leading directly to warranty cancellation. Instead, GAF recommends low-pressure, manufacturer-approved cleaning methods to protect both the roof and the warranty.
5. Neglecting Routine Maintenance
Failing to keep up with regular maintenance is a leading cause of voided warranties. If debris, moss, or failing flashing are left unaddressed, water damage or structural issues can result, and these are considered preventable problems by GAF standards. Schedule an annual professional roof inspection to ensure your system remains in good standing with GAF and to spot issues before they threaten your warranty.
6. Layering New Shingles Over Old Ones
Some homeowners believe installing a new layer of shingles on top of the old one is more economical, but GAF explicitly prohibits this for most warranty protections. Layering can hide underlying damage and compromise roof integrity. Always opt for a full tear-off during roof replacements so that your new warranty is valid and your roof performs as intended.
