Roofing Contractors in LancasterSymbium Permits, One-Layer Rule, Zone 14

Permits: Symbium, One Layer, No Wood Shake

Since September 1, 2025, every new residential reroof permit in the City of Lancaster goes through Symbium, the city's online permitting system, which issues the permit automatically when the job qualifies; if it doesn't, city staff take it from there. Inspections and fees run through the city's Accela portal. The city's reroof rules are short:

• One existing layer at most. You can reroof over a single existing layer; if there's more than one, all of them come off first.
• No wood shake or wood shingle. Neither is allowed in the City of Lancaster.
• Structural calculations only if the roof structure changes.

Homes in unincorporated communities around the city permit through LA County Public Works instead.

High-Desert Weather, by the Numbers

Lancaster sits in the Antelope Valley, and its weather is nothing like the LA basin's. NOAA's 1991–2020 normals for the Lancaster Fox Field station show:

That range is worth raising with any bidder: ask which products they use on Antelope Valley roofs and why. Rain is scarce, which is a reason not to put off a leak: a small one can go unnoticed for months between storms. The valley is Title 24 climate zone 14, where both steep-slope and low-slope residential reroofs need a cool-rated product unless an exception applies; see the Title 24 cool roof guide.

Solar, and a Mix of Old and New Roofs

Lancaster's homes span more decades than Palmdale's: 29% were built before 1980 and 62% between 1980 and 2009. Under a 2013 city ordinance, new homes permitted in Lancaster from 2014 on have to include solar, so many newer roofs carry panels, and a reroof means removing and reinstalling them; see reroofing with solar panels. Power is delivered by Southern California Edison, with Lancaster Choice Energy, launched in 2015, as the city's supplier. Check your parcel on CAL FIRE's 2025 fire hazard maps before choosing materials, especially toward the foothills.
