FAQ

Frequently Asked Questions

We install GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark. The three most popular architectural shingles in the country. All three are solid choices. GAF gives us access to the Golden Pledge warranty (25-year workmanship). Owens Corning Duration has SureNail technology for wind resistance. CertainTeed Landmark is a reliable mid-range option. We help you choose based on budget, color preference, and warranty goals.

Yes. We offer 12-month same-as-cash, low-interest plans up to 144 months, and no-money-down options through GreenSky and Hearth. Credit approval takes about 5 minutes. A new roof is a major expense. Financing lets you get it done now without draining your savings.

You get two warranties: one from the manufacturer on the materials and one from us on the workmanship. As a GAF Master Elite contractor, we can offer the Golden Pledge. That's 25 years on workmanship plus 50 years on the shingle. Owens Corning and CertainTeed have similar programs. Our own workmanship warranty is in writing and covers installation defects.

One day for most homes. Our crews are experienced and we pre-stage materials the day before install. Bigger or steeper roofs can run to two days. The dumpster shows up at 7 AM and leaves when we're done. Your life gets back to normal fast.

Depends on size, pitch, and materials. Average in Janesville is $12,000-$16,000 for a standard residential replacement with architectural shingles. We price by the square and itemize everything so you can compare to other quotes. Free estimates. Call (877) 349-1553.
