TRUSTED BY INDUSTRY LEADERS
Father And Son. Restaurant Roots. Contractor Results.
Most contractors started in someone's garage. We started in a kitchen. Our founder spent years managing restaurants before he ever picked up a tool. What he learned: people remember how you made them feel long after they forget what you charged them. That mindset followed him into contracting. Today, United Builders GC is a father-and-son operation serving the Inland Empire, Orange County, and LA. Roofing, solar, remodeling, painting, commercial. We answer the phone. We show up when we say we will. We walk you through everything before any work begins. And when the job is done, we walk you through it again. This is not a franchise. There is no call center. No layers. No runaround.

Frequently Asked Questions
Got questions about roofing, solar, remodeling, or commercial work? Here are the answers to the ones we hear most.
Get StartedMost projects begin with a 4-6 week planning phase for permitting, materials, and safety prep. Once construction begins, timelines vary by size. Small projects might wrap in under two months, while larger ones can span 10-14 weeks. Weather and site conditions can also affect duration.
In some cases, a roof overlay may be possible, saving time and money. But if there's structural damage, code restrictions, or multiple roof layers, a full tear-off may be the only safe and compliant option. A proper inspection is key to making the right call.
Booking in early spring or late fall can help you avoid peak season delays. Summer to early fall is busiest in the industry, so the earlier you plan, the more options you'll have, especially if you're managing multiple sites.
An inspection is the first step. Minor issues like punctures or seam separation can usually be repaired. But widespread damage, saturation, or age-related wear may point to the need for full replacement. We'll help you assess based on condition, risk, and budget.
