You called a few roofers, got some estimates back, and now you’re staring at numbers that feel way higher than you expected. You’re not alone — this is one of the most common reactions homeowners have when they start shopping for a new roof. So what exactly is driving that price?
First, roofing is skilled labor. Unlike a lot of home improvement tasks, replacing a roof requires trained crews working at height with heavy materials, specialized tools, and a tight timeline. Labor alone typically accounts for 40 to 60 percent of the total project cost, and experienced crews command higher rates — for good reason.
Materials are the next major component. Quality shingles from manufacturers like Owens Corning or GAF aren’t cheap, but they’re engineered to last decades. Add in the underlayment, ice-and-water shield, flashing, ridge cap, nails, and other components, and the material list adds up quickly.
Your estimate should also include disposal of the old roofing — hauling away torn-off shingles and debris isn’t free. Permit fees, which many homeowners forget to factor in, are another real line item depending on your municipality.
Then there’s the warranty. A contractor offering a lifetime labor warranty is building the cost of standing behind their work into their price. That’s not a red flag — it’s actually a green one.
Here’s the part most homeowners miss: a suspiciously low quote usually means something is being left out. Maybe they’re skipping the ice-and-water shield, using lower-grade shingles, or planning to skip the permit. You might save a few thousand dollars upfront and spend far more correcting problems down the road.
At GenSun Roofing, we’ve been in this business for 35 years and we price our work fairly and transparently. We’re consistently 10 to 20 percent lower than other quality roofers — not because we cut corners, but because we operate efficiently and pass those savings on to you.
When you receive a GenSun estimate, every line item is explained clearly, often with supporting visuals, so you understand exactly what you’re paying for and why. A high quote doesn’t have to mean an unfair one — it just has to be justified.
