Meet the Los Angeles Team Behind Mercer Roofing Co Los Angeles
Every roof in Los Angeles takes a beating from the sun, the Santa Anas, and the occasional winter downpour that sends water where it was never meant to go. The crew at Mercer Roofing Co Los Angeles knows this because we live here. We drive the same freeways you do, and we’ve seen what happens when a roof in Silver Lake or Sherman Oaks gets ignored for one season too many. What unites this team is simple: we show up on time, we badge in at the door, and we write the price down before a single shingle comes off. That’s the Threshold Standard, and these are the people who carry it onto every ladder in the city.

Our People
Raymond T. – Lead Technician
Raymond has been on Los Angeles roofs since before the 405 expansion made everyone rethink their commute. He started as a tear-off hand in the San Fernando Valley and worked his way up by doing the unglamorous things right: checking decking for dry rot, flashing chimneys so they don’t leak in the first big rain, and never leaving a jobsite until the magnet sweep is done. Raymond is manufacturer-certified on GAF and CertainTeed shingle systems, which means when a warranty claim hinges on correct nailing patterns, he’s the one who gets it right. Off the roof, Raymond restores old Schwinn cruisers and rides them along the LA River path on Sunday mornings when the traffic is actually tolerable.
Elena M. – Senior Installer
Elena came to Mercer Roofing Co Los Angeles after years of custom residential work in Pasadena and the hills above Glendale, where steep pitches and million-dollar views demand precision. She leads our full roof installation projects, from tearing off old shake in Eagle Rock to laying architectural shingles on new construction in Mid-City. Elena holds Owens Corning and Atlas installation certifications, and she’s the one who trains newer crew members on how to keep the underlayment tight and the ridge lines straight. Ask her about the time a roof on Mount Washington got hit with a microburst mid-install, and she’ll tell you how she got the whole deck re-secured before the homeowner got home from work. She bakes sourdough on the weekends and has strong opinions about which neighborhood bakery in Highland Park actually gets the crust right.
Priya S. – Service Coordinator
When you call Mercer Roofing Co Los Angeles, Priya is often the live voice on the other end of (213) 521-8272. She’s the person who takes your details, schedules the inspection, and makes sure the technician’s name and photo are sent to you before anyone knocks on your door. Priya knows the city block by block, from the flat commercial roofs of Vernon to the hillside homes of Los Feliz, and she can usually tell you what to expect before we even send someone out. Before joining Mercer, Priya worked in dispatch for a plumbing company in Koreatown, so she’s heard every version of “my roof is leaking” a homeowner can muster. She keeps a running list of the best breakfast burritos within a mile of our service area, and she shares it freely with new technicians.
Danny W. – Apprentice Technician
Danny is the youngest member of our Los Angeles crew, and he’s earning his place the same way everyone else did: by carrying bundles up ladders, keeping the ground clean, and learning from Raymond and Elena on every job. He’s currently working toward his first manufacturer certification in IKO shingle installation, and he’s already got a good eye for the small things that cause big leaks, like improperly lapped flashing or valley metal that’s shifting. Danny grew up in Long Beach and spent two years doing finish carpentry before he found his way to roofing. He’s the reason every Mercer jobsite in Los Angeles gets a final magnetic sweep before we leave, because Danny’s the one who ends up doing it most days, and he takes it seriously.
One Standard, Every Job
The Threshold Standard isn’t a slogan we put on a shirt. It’s the framework every crew member at Mercer Roofing Co Los Angeles is held to on every single visit, whether we’re repairing a small leak in Koreatown or rebuilding a roof in the Palisades. Every technician is background-checked and identity-verified before they ever step onto your property. They arrive in a clean, marked uniform with a photo ID badge they present at the door. Their name and photo are sent to you before they arrive, so the person who shows up is the person we said was coming. Grant Whitlock, Owner of Mercer Roofing Co Los Angeles, has held this line since the company was founded in 2000, and it’s why every repair gets a written guarantee, every job gets a written price before work starts, and every homeowner gets a straight answer. That’s how roofs get done once and done right in this city.
