FAQS

Why should I hire a GAF certified roofer instead of a regular roofer?

A GAF certified roofer is trained, tested, and approved by GAF to install their products correctly. This gives you access to better-quality installations and stronger warranty options compared to non-certified contractors.

How long does a GAF roof installation take?

Most GAF roof installations in Fort Collins are completed within one to two days, depending on roof size and weather. Certified installers follow GAF’s process to ensure everything is done correctly and efficiently.

Are GAF roofs good for hail-prone areas like Fort Collins?

Yes. Many GAF roofing systems are designed with impact-resistant technology that helps protect against hail damage, making them a reliable choice in Colorado.

How do I know if my home needs a new GAF roof?

Signs include missing shingles, leaks, granule loss, storm damage, or a roof that’s over 20 years old. A GAF certified roofer can inspect your roof and recommend the right solution.

Is GAF roofing more expensive than other brands?

Not necessarily. GAF offers a wide range of shingles, from budget-friendly options to premium lines. Homeowners in Fort Collins often find the durability and warranty value worth the investment.
