Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
Fast, Reliable Roofing Company Across Poway
A typical roof repair in Poway runs $450 – $1,800, while a full re-roof on a 1970s – 90s tract home generally lands between $14,000 and $28,000 depending on pitch, decking condition, and whether the parcel sits in a CAL FIRE Very High Fire Hazard Severity Zone. Most jobs here start with a written price before a single tile is lifted. We know Poway’s gable-heavy rooflines, steep hillside lots, and the fire-code rules that change what a “simple fix” actually costs. Call (743) 200-8347 and a live person answers, 24/7.

Why Mercer Roofing Is Poway’s Preferred Roofing Company
Poway homeowners call us because we treat their house as a place to be protected, not a job site. The big differentiator is simple: you know exactly who is coming. We send each technician’s name and photo before they arrive, and they present a photo ID badge at the door. For a parent home alone with young kids, or an older homeowner in Rancho Arbolitos, that proof at the threshold is worth more than any slogan.
Our Roofing Company teams work Poway every week – from the Spanish-style tracts near Twin Peaks Road to the hillside lots off Espola Road. We’ve walked hundreds of roofs in this city. We know what the afternoons above 100°F do to old concrete tile ridge caps in Old Coach Road neighborhoods. We know the Santa Ana window when an inspector starts looking hard at ember exposure. We plan around tight lots where staging on the street means coordinating with neighbors before a single bundle hits the ground.
Every repair includes a written guarantee. If a repair fails within a year, the second visit is free. That is not a wink and a handshake. It is printed on the estimate and signed before the work begins.
Founded in 2000, Mercer Roofing is part of the Threshold Group family of home-service companies. Each location is independently owned and operated and held to the Threshold Verified standard – background-checked, photo-badged, uniformed technicians on every visit. No subcontractor roulette.
Commercial Roofing in Poway
Commercial Roofing in Poway covers the low-slope and flat roofs on the city’s retail centers, office parks, and industrial buildings along Poway Road and Scripps Poway Parkway. A commercial leak on a built-up or modified bitumen roof in Poway typically runs $800 – $4,500 to repair, while a full commercial re-cover or replacement on a 5,000 – 15,000 square foot building generally falls between $35,000 and $110,000 depending on insulation, decking, and the fire-assembly requirements tied to the parcel’s FHSZ designation.
Poway’s inland heat means commercial roof membranes here age faster than they do in coastal San Diego. Thermal cycling on a 105°F afternoon stresses seams and flashing. We inspect roof penetrations, drain lines, and any area where standing water pools after a winter storm – because those are the spots that fail first on a Poway commercial roof.
Flat Roof Repairs and Coating
Small punctures, split seams, and failed pitch pockets get patched and sealed. We use materials matched to the existing assembly, and we photograph every step so the property owner sees exactly what was opened and what was done.
Full Commercial Replacement
When decking rot or widespread membrane failure makes patching a losing game, we strip to the substrate, replace compromised wood or insulation, and lay a new assembly that meets Poway’s current fire-code requirements. Permits are pulled, inspections are passed, and pricing is written before anything is removed.
Metal Roof Installation in Poway
Metal Roof Installation in Poway is a smart option for homeowners in the fire-zone parcels where Class A assemblies matter most. A standing-seam or stone-coated steel roof on a typical Poway ranch home runs $22,000 – $48,000, with stone-coated products like certain Boral profiles coming in at the upper end. The price reflects material, roof complexity, tear-off of the old tile or shake, and whether the decking needs repair before new underlayment goes down.
Metal is fire-resistant, sheds embers, and handles Poway’s thermal extremes better than asphalt shingles. It also weighs less than concrete tile, which matters on some of the older 1970s truss systems we find in neighborhoods south of Poway Road. That said, metal roofs here need proper fastening for Santa Ana wind uplift – a roof that would sit fine on a coastal home can peel at the ridge in a 60 mph gust if the install is sloppy.
Stone-Coated Steel
Stone-coated steel gives the look of tile or shake but carries a Class A fire rating and stands up to the UV exposure Poway brings. It is quiet in the rain, holds up under thermal cycling, and needs far less maintenance than mortar-set tile.
Standing Seam
Standing-seam panels run clean lines, handle steep pitches well, and hide all fasteners under the seam. We install them with proper clip systems that allow thermal movement – critical when a Poway summer roof surface can hit 140°F and then drop 80 degrees overnight.
Trusted Brands We Service in Poway
We install and repair roofs using manufacturer-recognized shingle and tile brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means warranty support comes directly from the manufacturer, not just from us. For Poway customers, we stock local parts: ridge cap, underlayment fasteners, drip-edge profiles, and matching tile colors for the 1970s – 90s tract homes that dominate this market. When a cracked tile on your Spanish-style ranch needs a matching replacement, we can usually find it same-week without ordering from out of state. Fast turnaround matters when a Santa Ana wind event has torn a ridge cap off and the next gust is two days out.
Common Roofing Company Problems We See in Poway Homes
- Cracked ridge cap mortar from 100°F thermal cycling. Poway’s inland heat expands and contracts mortar joints faster than coastal temps ever do. Hairline cracks let water in, and in a fire zone, they are an ember entry point an inspector will flag.
- Brittle underlayment on 1970s – 80s concrete tile roofs. The tile may look fine while the felt below it has dried out and split. A tile reset turns into a full decking strip once we open it up – which is exactly why our written price process matters.
- Wood shake roofs that are now non-compliant. Thousands of Poway homes were built with shake, and many still have it. Insurance carriers are requiring Class A replacements, and the permit pull on an FHSZ parcel is not optional.
- Santa Ana uplift on gable-heavy rooflines. Old fasteners loosen over time. A gust hits a gable end, peels a section of tile, and suddenly the whole roof is exposed. We check fastener patterns on every inspection, not just the visible tile surface.
Pricing for Roofing Company in Poway, CA
Here are the ranges we quote in Poway, based on jobs we have actually done here. A spot repair – cracked tile reset, small flashing patch, or minor leak seal – runs $450 – $900. A larger repair involving valleys, penetrations, or underlayment replacement lands between $1,200 and $3,800. Full re-roofs on standard Poway tract homes run $14,000 – $28,000 for architectural shingles, with concrete tile or stone-coated steel pushing $22,000 – $48,000. Decking repair adds $2 – $4 per square foot when rot or dry-rot is found. The fire-zone trigger is real: if your parcel is in a Very High Fire Hazard Severity Zone, a partial re-roof just became a full Class A assembly. That is not us upselling. That is the code.

FAQs About Roofing Company in Poway
Yes, if your parcel is in a CAL FIRE Very High Fire Hazard Severity Zone, the city inspects the entire roof assembly – not just the repaired section – when the permit is pulled. Ridge cap mortar, underlayment type, and starter strip all get reviewed. We flag this on the estimate before work begins, so there are no surprises at inspection. Call (743) 200-8347 and we’ll check your parcel’s FHSZ status for free.
We send neighbor notice before a tear-off, stage materials on the driveway rather than the street when possible, and keep a magnet sweep running through the whole job. On shared-wall or close-lot parcels we lock in work-hour communication up front. A clean, calm site is part of the Mercer standard. Call us for a written plan on how we’d handle your specific lot.
Hillside lots off Blue Sky Reserve or Old Coach Road often need extra equipment or hand-carrying when a truck can’t get close to the house. Steep driveway grades, tight turnaround space, and long carry distances add labor hours. It is not a mystery charge – it shows up as a line item on the written estimate so you know before you sign. Call (743) 200-8347 for a site walk that accounts for actual access conditions.
Your options are a full tear-off and replacement. Wood shake is non-compliant in Poway’s fire-zone parcels, and most insurance carriers will not renew a policy over it. We replace shake with Class A architectural shingles, concrete tile, or stone-coated steel, and we handle the permit and the FHSZ compliance review as part of the job. Written pricing before demolition starts, every time.
Santa Ana conditions shift our focus from water intrusion to wind uplift and ember exposure. We check fastener patterns and ridge cap mortar specifically when a Santa Ana event is in the forecast, because those are the components that fail first in a fire zone. We also seal any exposed wood-based underlayment before the ember cast arrives. Call us before the next wind event – a written inspection is free with every estimate.
