MATERIALS & SYSTEMS
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.
YOUR PROJECT, YOUR PRIORITIES
Understand what goes into the system.
Select a starting point. We’ll confirm the right scope with an inspection.
Choose shingles, starter and ridge together.
The shingle color is only one decision. Starter strips and hip and ridge products should be specified with the chosen roof system.
- What we look at
- The exact GAF product names, colors and compatible accessories in your proposal.
- Bring to the conversation
- Use the GAF visualizer to narrow down a few colors.
Plan the vulnerable connections.
Roof deck protection, leak barriers and flashing each have a role. Their placement should reflect the roof’s shape and exposure.
- What we look at
- Eaves, valleys, penetrations, chimneys, skylights and deck condition.
- Bring to the conversation
- Point out any past leaks or ice-related trouble spots.
Confirm the details of your installation.
Ventilation and warranty eligibility need to be reviewed for the actual system. A brand name alone does not define the coverage.
- What we look at
- Intake and exhaust, required components and applicable registration requirements.
- Bring to the conversation
- Request the written material and workmanship terms before approving.
