Built here in the Bay Area
Finished GAF roofs, active installs, and the crews that put them together.
Why roof quotes can be thousands apart
One Bay Area roof can draw bids from $18,000 to $40,000. The same shingles can carry very different totals once sales costs and pricing methods are added.
The typical roofer
The commission is built into the bid
A 30–40% sales commission can add $3,000 to $8,000 before the crew touches your roof.
The estimator controls the number
You see one price after a sales appointment, with little room to check how it was built.
Comparing takes days or weeks
Every new number means another appointment, another pitch, and another round of follow-up.
The pitch comes before the details
You are asked to buy before you can compare every system and line item side by side.

Read what homeowners say after the roof is done
"I got three quotes from traditional roofers, all $15k+. Hamilton's online price was $11,200 for better materials. The savings from cutting out the salesman are real."

"Roof City did an excellent job on my roof. They were professional, fast, efficient, and clean. They over- delivered on their promise to do a five- star job in two days, which included all materials and permits needed…"

Questions homeowners ask us
How can you price my roof without visiting first?
Satellite imagery gives us the size, pitch, and shape of your roof so you can see a real starting price now. Before work begins, a Hamilton project manager visits your home to confirm the measurements and inspect anything the imagery cannot show.
Why is Hamilton’s price lower than many roof quotes?
A traditional roofing quote often carries a 30–40% sales commission. Hamilton lets you price the roof online, compare all three GAF systems, and put more of your budget into the roof itself instead of an in-home sales pitch.
What warranty comes with my roof?
Every system includes a GAF manufacturer warranty, from 25 years to lifetime depending on the material you choose, plus Hamilton’s 35-year labor guarantee. Hamilton is a GAF Master Elite contractor, a certification held by fewer than 2% of roofers nationwide.
Can I finance the roof?
Yes. Approved homeowners can choose 0% APR financing for up to 60 months during checkout. The application takes about two minutes, and there are no prepayment penalties.
What if the on-site visit changes the price?
You will see exactly what changed and why. We update the itemized quote, and you approve any change before the job moves forward. The decision stays with you.
How long will my roof replacement take?
Most residential roofs take 1–3 days, depending on size and complexity. Hamilton handles the permits, material delivery, installation, cleanup, and final walkthrough.
