About us
One company. One standard. One way.
The name isn't a slogan — it's a filter. There's one way we install a roof: to the manufacturer's spec, with photos to prove it, backed in writing. If a job can't be done that way, we don't take it.
Our story
Started on the roofs of Downey.
One Way Roofing was founded by roofers who'd spent years watching the same story repeat: a storm rolls through, out-of-town crews flood the neighborhood, and homeowners end up with vague bids, rushed installs, and warranties nobody honors.
We decided to be the opposite of that — a local shop on Firestone Boulevard where the person who quotes your roof is accountable for it, every install follows the spec sheet, and the phone gets answered at 2 AM because that's when roofs fail.
Today our crews handle everything from a single slipped tile to full commercial re-roofs across LA County. The standard hasn't moved.
How we work
Four rules we don't bend.
01
Do it once
Spec-sheet installs, no shortcuts. If something isn't right, we redo it on our dime — that's what the written warranty is for.
02
Say it straight
Photos and plain English. If the honest answer is "your roof is fine," that's the answer you get.
03
Leave it cleaner
Daily cleanup, protected landscaping, and a magnetic nail sweep before we call any job finished.
04
Answer the phone
24/7, 365. During the job, after the job, and at 2 AM in a storm three years later.
