Complete roof replacement on our Chula Vista home - $14,200 total, done in under 2 days. Robert and his crew arrived on time, protected our landscaping, and left the yard spotless. The city inspection passed on the first visit. GAF Timberline shingles look incredible. Best contractor experience I have ever had.
Roof was leaking badly during a San Diego rainstorm in Carlsbad. Called at 10pm and they were at my house in under 45 minutes. They tarped the roof that night and completed the $4,800 repair the next morning. The insurance claim was fully approved and they handled all the paperwork. Incredible service.
30-year-old roof in Santee finally needed full replacement. Total cost $18,500. The crew discovered rotted decking and repaired it at no extra charge. They pulled all permits, coordinated the city inspection, and finished on schedule. I have already recommended them to three neighbors on my street.

25-30 years is the average lifespan of a standard asphalt shingle roof in San Diego's climate, per NRCA guidelines. San Diego's 65+ annual sunny days and high UV intensity accelerate shingle degradation compared to wetter climates. Premium GAF Timberline HDZ shingles carry a limited lifetime warranty. Metal roofing systems last 40-70 years. Regular maintenance and annual inspections extend any roof's life by 5-7 years (NRCA).
$200-$450 is the typical City of San Diego Development Services permit fee for residential roof replacement, required for any tear-off and replacement exceeding 25% of the existing roof area. Our CSLB C-39 #1087543 license authorizes us to pull all required permits on your behalf.
