4.9 stars · 471 verified reviews

Simi Valley extends our service area into Ventura County, where we work across the 93063, 93065, and 93066 zip codes. Simi Valley's housing stock skews newer than much of LA - many homes here are 1980s–2000s construction that's approaching or past the 25-year mark for original asphalt shingle roofs. The city's inland location means hot, dry summers and Santa Ana wind events that test roof fastening systems.

We specify SureNail technology on all Simi Valley projects for wind resistance, and we've completed multiple full replacements and repairs throughout the city. Simi Valley Building & Safety permit requirements are separate from LA County, and we handle the full process..

Frequently Asked Questions — Roofing in Simi Valley

Do you handle Ventura County building permits for Simi Valley?
Yes. Simi Valley Building & Safety is separate from the City of LA and LA County — it's the City of Simi Valley's own building department. We're familiar with the Simi Valley permit process and handle the full application, including any cool-roof documentation required for re-roof permits. Turnaround times are generally comparable to other jurisdictions we work in. There's no extra process for you as the homeowner — we manage it entirely.
How do Santa Ana winds affect roofing in Simi Valley?
Santa Ana wind events are a real design consideration for Simi Valley roofing. High-wind uplift can pull fasteners loose or lift shingles on roofs that weren't installed to modern wind-resistance standards. We specify Owens Corning SureNail technology on all Simi Valley installations — a nailing strip embedded in the shingle that provides measurably better fastener holding power. We also pay close attention to starter strip installation and edge metal detailing, which are the most common failure points in wind events.
When should I replace the roof on my Simi Valley home?
Many Simi Valley homes are 1980s–2000s construction with original asphalt shingle roofs now hitting or passing the 25-year mark — right at the end of the typical service life for three-tab shingles in a hot, dry climate. If your home falls in that age range, a professional inspection is worth doing even if you haven't noticed any leaks. Leaks are often the last symptom to appear — by then, there may already be water damage to the underlayment or decking.
