THE WORK BEHIND THE FINISH
Protection is in the details.
A GAF roof combines the visible shingles with the layers and accessories beneath and around them. We explain what is included in your roof and the warranty options available for the selected system.
The layers beneath
Review roof deck protection, leak barriers and flashing around the most exposed details.
Airflow & coverage
Include ventilation in the plan and review the eligibility requirements of the selected warranty.
Is Optimal a GAF Certified contractor?+
Yes. You can view Optimal Home Improvement’s contractor profile on the GAF website.
Which GAF warranty can I get?+
Eligible installations may qualify for enhanced coverage, including the GAF System Plus Limited Warranty. The exact coverage depends on the products, installation and registration requirements. Request the written terms.
Why choose a system instead of shingles alone?+
Underlayment, leak barriers, starter strips, ridge caps and ventilation each have a role. Planning the components together helps make the installation scope clear.
