FAQs

Why are GAF roofing materials a smart choice for homes in Johnson City?

GAF is North America’s largest roofing manufacturer and engineers its shingles specifically to handle diverse regional climates like ours. Johnson City experiences hot, humid summers, heavy rainfall, and the occasional winter freeze. GAF’s advanced asphalt formulas, fiberglass mat cores, and patented LayerLock™ technology give their shingles a Class A fire rating, 130 mph wind resistance (with the required accessory system), and StainGuard® algae protection—features that collectively combat UV exposure, wind-driven rain, and algae staining common in East Tennessee. The result is a roof that looks great and performs reliably for decades.

What does “Roofing Done Right” mean in your installation process?

“Roofing Done Right” is our commitment to precise workmanship and strict adherence to GAF’s installation guidelines. Every project begins with a free on-site inspection and digital roof measurement. We remove old materials down to the decking, replace any rotten wood, install proper drip edge, leak barrier, and a full layer of GAF Deck-Armor® or Tiger Paw™ underlayment. Next, we install your selected GAF shingles using six-nail fastening patterns and LayerLock™ factory-printed nailing zones for accuracy. All flashing, ridge vents, and sealants are GAF-approved products, ensuring the entire roofing system qualifies for enhanced warranty coverage. A final 40-point quality check and job-site cleanup make sure your roof is truly “done right.”

Which GAF shingle lines do you offer, and how do I choose the best one?

We stock the most popular GAF architectural and designer series: Timberline HDZ®, Timberline UHDZ™, Timberline® AS II (impact-resistant), and the premium Glenwood® and Slateline® lines. Timberline HDZ is our best-seller, balancing cost and performance for most Johnson City homes. If you want higher curb appeal and thicker shadow lines, UHDZ delivers an ultra-dimensional look. For hail-prone areas, Timberline AS II’s Class 4 impact rating can lower insurance premiums. Historic homes often look stunning with Glenwood’s triple-layer shake aesthetic. During your consultation we assess roof pitch, ventilation needs, neighborhood HOA rules, and your budget to recommend an ideal shingle and color blend.

How long can I expect a GAF roof to last in Johnson City’s climate?

When installed by a GAF Certified™ contractor like us, most GAF Lifetime architectural shingles last 25–30 years on average in Johnson City, with many roofs surpassing 35 years when properly ventilated and maintained. The shingles’ Advanced Protection® asphalt resists thermal cracking during hot summer days, while their Dura Grip™ adhesive seals tabs tightly against high winds. Annual gutter cleaning, attic ventilation checks, and quick repairs to storm damage can extend your roof’s service life to the upper range of its expectancy.

What warranties come with GAF materials and your installation?

All GAF Lifetime shingles automatically include a Lifetime Limited Material Warranty plus 10 years of Smart Choice® protection for non-prorated material and installation labor costs. Because we participate in GAF’s Certified™ program, you can upgrade to the System Plus (20-year workmanship) or Golden Pledge® (25-year workmanship) warranties, which also cover tear-off, disposal, and wind damage up to 130 mph when the full GAF roofing system is installed. These warranties are transferrable once in the first 20 years, adding resale value to your Johnson City home.

How do I begin a roofing project with your team and what’s the typical timeline?

Start by calling or filling out our online form to schedule a no-obligation roof inspection—usually booked within 48 hours. After the assessment, we provide a detailed proposal, shingle samples, color visualizations, and financing options if needed. Once you approve, we pull permits and order materials; lead time is 1–2 weeks, depending on shingle selection. Most residential tear-off and replacements take 1–3 days, with larger or more complex roofs requiring up to a week. A final walkthrough, photographic documentation, and warranty registration complete the project, ensuring you receive proof of coverage and total peace of mind.
