Treggo Lume Home Roofers provides roofing services in Simi Valley, California, from 1712 Erringer Rd, Simi Valley, CA 93065. Call (805) 669-9300 for a written scope after inspection of the actual roof.
Simi Valley is an incorporated city in Ventura County, and permits inside city limits run through the City of Simi Valley Building & Safety Division, not through LADBS.
Roof work here is driven by inland heat, concentrated winter rain and Santa Ana wind, and the scope for each home follows its era, roof type and parcel fire-zone status.
For a single-family re-roof in CEC Climate Zone 9, the Title 24 Part 6 prescriptive cool-roof values are an aged solar reflectance of at least 0.20 with thermal emittance of at least 0.75, or an SRI of at least 16, on steep slopes of 2:12 or more, and at least 0.63 with emittance of at least 0.75, or an SRI of at least 75, on low slopes under 2:12. That requirement is triggered when more than 50 percent of the roof area is replaced, which is a different threshold from the City permit trigger, and the parcel's zone should be checked with the CEC zone finder before a product is specified.
Simi Valley contains High and Very High Fire Hazard Severity Zone parcels, but it is not correct to say that all of Simi Valley is Very High. The parcel's zone must be checked in the CAL FIRE / VCFD Fire Hazard Severity Zone viewer, and on a wildland-urban interface parcel the current citation is Title 24 Part 7, the California Wildland-Urban Interface Code, not the retired CBC Chapter 7A. On such a parcel a Class A fire-rated roof assembly is required.
We fix the cause, not just the symptom, and we show you the proof.
Published regional market ranges include architectural asphalt at $550 to $900 per square and tile re-lay at $900 to $1,600 per square in a Torrance / South Bay 2026 guide, and California repair work most commonly at $450 to $3,200 in a Modernize guide updated 26 August 2026. One square is 100 square feet of roof surface, not floor area, and a written estimate follows inspection of the actual roof.

A written scope follows inspection of the actual roof, because size, pitch, number of layers, material, access, and permit requirements all change the work. This website does not publish a firm price for this business; published market ranges elsewhere on this site are labelled as market data, not as a quote.
The better choice depends on the house: tract or hillside position, roof pitch, weight the framing can carry, fire-zone status, and ventilation. Compare those factors for the actual roof rather than a single ‘best’ label, and confirm permit and fire-zone requirements for the parcel.
For an active leak, limit interior water damage, avoid walking on a wet or damaged roof, and call (805) 669-9300 to discuss make-safe work such as tarping. Tarping is temporary, not a repair, and no arrival or completion time is promised on this website.
Check the contractor's CSLB C-39 licence on the CSLB tool, ask how the permit, underlayment, flashing, ventilation and disposal are handled, and get the scope in writing before work starts. Ask whether the figure is a firm scope or an estimate, and what is excluded.
