What we do
Firmament Roofing takes on full roof jobs. A homeowner or building manager describes the roof and the job. We read it, note which code items probably apply at that address, and arrange an assessment that looks at the roof layer by layer.
The name comes from how we think about the job. A roof is a stack: framing, deck, waterproof layers, flashing, then the visible covering. Problems that show up on the surface usually start lower down, so our pages explain each layer and what a replacement does to it.
We give you a clear description of the work, the rules that apply in Los Angeles County, and the checks to make before you sign any roofing contract, ours included.
How requests are handled
Four habits shape every page and every request.
Structure first
A replacement is described from the deck outward. If the boards are unsound, nothing laid over them will last, so the deck comes before any talk of color or brand.
Full jobs lead
We lead with full jobs: replacements, tear-off reroofs and new roofs. The form takes any roof job, and we weigh repair against replacement honestly.
Code named early
Cool roof values, fire class and the permit path change what a bid should contain. We name them on the page for your place, with their source.
Everything in writing
The scope, the contract and the permit are settled in writing before work starts.
What a homeowner should check before signing
Ask for a written scope. Confirm the permit is pulled before work starts.
Questions about roofers
How many roofing contractors are in the US?
No source we found gives a company count. The Bureau of Labor Statistics counts 166,900 roofer jobs in the US for 2025, and that figure is workers, not businesses. For the Los Angeles-Long Beach-Anaheim area the same agency estimated about 4,680 roofers in May 2023.
Can a general contractor do roofing work in California?
Whoever does the work, a roof job runs on paper: a written scope, a contract that follows California's home improvement rules and a permit.
How long does the average roofing contractor stay in business?
A manufacturer's product warranty comes from the maker, so it does not depend on the installer staying open.
