How a Free Roof Quote Works

Simple. Honest.
No pressure.

We know how roofing companies usually work. The high-pressure pitch, the “today-only discount,” the contract on a clipboard. That’s not us. Here’s how we do it instead.

Call & describe your project

A senior estimator answers — usually under 30 seconds — and asks the right questions to understand your roof.

We come out and inspect

We climb your roof, document it on video, and write up a real quote with real materials and a real timeline.

You decide. No pressure.

Take a week. Get other quotes. Show your neighbor. If you don’t like ours, you owe us nothing — not even a follow-up call.

Common Questions · Roofing Company Near You

Roofing questions,
answered honestly.

Are you a licensed roofing contractor?
Yes. Grandmark Service Company holds California contractor’s license #1030917 and carries full general liability and workers’ compensation insurance. Our license is verifiable on the CSLB website at any time.
Do you provide free roofing estimates?
Yes. We provide free, no-pressure roof quotes for homeowners considering roof replacement or major repair. A senior estimator visits your home, climbs your roof, and gives you a real number — not a high-pressure sales pitch.
What residential roofing services do you offer?
We’re a full-service residential roofing company offering roof replacement, roof repair, leak repair, storm damage repair, video roof inspections, and roof maintenance. We work with asphalt shingle, composition, tile, flat/low-slope, modified bitumen, and TPO roofing systems.
How long does a roof replacement take?
Most residential roof replacements take 1 to 3 days depending on the size of the home, the existing roof condition, and the materials being installed. Tile and complex roof lines can take longer. We give you a precise timeline before any work begins.
Do you offer financing for roof replacement?
Yes. We offer roof financing with flexible terms, including options for qualified homeowners. Call (209) 242-8674 and a senior estimator will walk you through the options based on your project.
How long do residential roofs last?
Asphalt shingle roofs typically last 20-30 years. Tile roofs can last 40-50+ years. Flat/low-slope membranes vary by material. The actual lifespan depends heavily on install quality and ventilation — which is why we record every install on video so you can verify the workmanship.
