Choosing the right roofing contractor is one of the most important decisions you'll make as a homeowner. A quality roof replacement is a significant investment that should last 25-50+ years—but poor workmanship, unlicensed contractors, or unscrupulous business practices can turn your investment into a costly nightmare.
This guide will help you evaluate roofing companies in Los Angeles and make an informed decision based on the factors that truly matter.
🚩 Red Flags: Warning Signs to Avoid
Before we discuss what to look for, here are critical warning signs that should send you running:
No License or Insurance
Requires upfront payment of 50% or more before work begins
Pressure to Sign Immediately
"Today only" pricing or aggressive sales tactics
Cash-Only Payment
No credit card acceptance or written contract provided
No Written Warranty
Verbal promises only, no documented workmanship guarantee
Door-to-Door Solicitation
"Storm chasers" offering to inspect your roof after weather events
Lowest Bid by Far
Quote significantly lower than others (likely cutting corners)
Essential Factors to Evaluate
1. Valid License & Insurance
This is non-negotiable. In California, roofing contractors must have a valid C-39 Roofing Contractor License issued by the Contractors State License Board (CSLB).
What to Verify:
- •Active C-39 license (verify at CSLB.ca.gov)
- •General liability insurance (minimum $1M coverage)
- •Workers' compensation insurance (protects you from liability if workers are injured on your property)
- •Contractor's bond (required by state law)
2. Proven Experience & Local Reputation
Roofing is a skilled trade that requires years of experience to master. Look for contractors with a proven track record in Los Angeles and surrounding areas.
Questions to Ask:
- •How long have you been in business? (Look for 10+ years)
- •How many roofs do you install per year in Los Angeles County?
- •Can you provide references from recent projects in my area?
- •Do you have manufacturer certifications from GAF, Owens Corning, or CertainTeed?
3. Strong Workmanship Warranty
A contractor's workmanship warranty is their promise to stand behind their installation quality. Industry standard is 1-2 years—but experienced contractors offer much longer.
What to Look For:
- •Minimum 5-year workmanship warranty (10+ years is excellent)
- •Written warranty document (not just verbal promises)
- •Clear coverage terms (what's included, what's excluded)
- •Transferable warranty (adds value if you sell your home)
4. Transparent, Detailed Pricing
A professional contractor provides detailed, written quotes with clear line items—not vague estimates or suspiciously low prices.
Your Quote Should Include:
- •Itemized material costs (shingles, underlayment, flashing, etc.)
- •Labor costs and crew size
- •Tear-off and disposal costs
- •Permit fees and inspection costs
- •Payment schedule (avoid large upfront deposits)
- •Project timeline and completion date
5. Professional Communication & Customer Service
How a contractor communicates during the sales process is a strong indicator of how they'll treat you during and after the project.
Good Signs:
- •Prompt responses to calls and emails
- •Willingness to answer questions and explain options
- •No pressure tactics or hard sells
- •Professional presentation and demeanor
- •Clear project timeline and expectations
