TopCal Roofing replaces roofs across Pasadena and all of Los Angeles County with asphalt shingle, clay tile, TPO, and metal — backed by manufacturer warranties up to 50 years. Free inspection included. $500 OFF any replacement.
A roof replacement is a major investment — but waiting too long costs far more. Pasadena's intense summer heat, UV exposure, and periodic Santa Ana wind events accelerate wear on every roofing material. Our licensed inspectors help you make the right call: repair or replace.
These signs indicate that full replacement is the smarter financial decision:
If two or more of these apply, full replacement almost always delivers better long-term value than continued patching. We'll tell you honestly which way to go — we don't upsell replacements when a repair will do the job.
Certified installers of all major residential roofing materials. Every job comes with a manufacturer warranty and our workmanship guarantee.
The most popular choice for Pasadena homes. We install Owens Corning Duration Series — algae-resistant, wind-rated up to 130 mph, available in 30+ colors. Most cost-effective with a 25–30 year lifespan in Southern California's climate.
