Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
Fast, Reliable Roofing Company Across East Hemet
Roofing work in East Hemet runs on two different tracks, and most roofers only know one of them. A standard asphalt-shingle re-roof makes sense on the tract homes north of Highway 74, but step into the unincorporated mobile home parks off Stetson Avenue or south of Florida Avenue and you’re looking at low-slope HUD-code panel roofs that need elastomeric coating, TPO overlays, or full metal-panel replacement. Mercer Roofing handles both, with written pricing before any work starts and a 365-Day Done Right Promise on every job. If you need a Roofing Company that knows which permit track your address falls under, call (743) 200-8347 for a free estimate.
Why Mercer Roofing Is East Hemet’s Preferred Roofing Company
East Hemet homeowners call us because we send the technician’s name and photo before anyone rings your doorbell. That matters here. People are often home alone during the day, parents have young children napping, and older homeowners want proof of who’s at the door before they open it. Every Mercer technician is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. It’s the Threshold Verified standard, and we’re held to it on every visit, no exceptions.
We also answer the phone with a live person, 24/7. Not a voicemail. Not a call-back form. When a Santa Ana wind event tears a panel loose at 2 a.m., you get a human being on the line who can dispatch a crew to East Hemet. Grant Whitlock leads our team, and he built our reputation on showing up when we say we will and putting every price in writing before a single nail is driven.
Our East Hemet customers keep calling back because we don’t guess at the roofing system your home actually needs. We inspect the slope, the deck, the fasteners, and the existing membrane before we quote anything. That pre-inspection is the difference between a roof that survives the next 105°F summer and one that fails at the seams in three years.
Commercial Roofing in East Hemet
Commercial Roofing in East Hemet means something specific: low-slope and flat roofs on the small retail strips along State Street, the storage buildings and auto shops near the Highway 74 corridor, and the office pads tucked into the unincorporated commercial pockets east of Hemet. These buildings take the worst of the San Jacinto Valley sun, and their membranes cook faster than anything on the coast. A typical TPO overlay or full commercial membrane system in East Hemet runs $8,000 to $45,000 depending on square footage, insulation replacement, and how many rooftop units need re-flashing. Written pricing always comes first, and the 365-Day Done Right Promise applies to every commercial job we do.
TPO and Elastomeric Coatings for Flat Roofs
East Hemet’s inland elevation and intense UV load means flat roofs need a system that reflects heat rather than absorbing it. TPO membrane in white or light grey is the standard call for most commercial buildings here, and we install it over the existing deck after addressing ponding areas. Elastomeric coating restores older built-up roofs and buys years of service before a full tear-off is necessary.
Re-Flashing and Drainage Correction
Commercial leaks in East Hemet rarely start in the field of the roof. They start at penetrations, curbs, and scuppers where the original flashing has oxidized and separated. We re-flash every penetration and correct drainage so water stops pooling at the low points. A full commercial inspection with written findings is the best starting point, and it’s included with every estimate.
Metal Roof Installation in East Hemet
Metal Roof Installation in East Hemet is not a niche upgrade. It’s the correct repair for thousands of older manufactured homes whose original low-slope steel or aluminum panels have backed-out fasteners and oxidized seams. We pull the failed sealant, reset or replace fasteners, re-seal the roof-to-wall joints, and set new drip edge. On the worst ponding areas, we spot-set TPO over a base of elastomeric coating. A full metal-panel replacement on an average East Hemet manufactured home runs $9,000 to $18,000. A fascia-to-ridge residing with standing seam runs $18,000 to $35,000 on larger double-wides, and that includes the permitting work through Riverside County Building and Safety.
Panel Repair vs. Panel Replacement
If the panels themselves are sound, we repair. Backed-out fasteners get reset, oxidized seams get cleaned and sealed, and the leading edge gets new drip edge and roof-to-wall sealant. That’s $2,500 to $6,500 on most homes. If the panels are corroded through or the deck is soft from years of slow seep, replacement is the honest call.
HUD-Code Roof Overs and Permitting
East Hemet’s manufactured homes are HUD-code structures, not site-built houses. The permit path runs through Riverside County Building and Safety, not a city building department, and the county inspects the roof-to-wall connection as part of the sign-off. We document existing conditions before we touch the deck, so your original builder warranty stays intact if the home is still under coverage.
Trusted Brands We Service in East Hemet
We install and repair GAF, CertainTeed, and Owens Corning shingle systems on East Hemet tract homes, and we stock local parts for those brands so we’re not waiting on a distributor in Riverside when your roof needs work. For manufactured homes, we work with the metal panel and TPO membrane lines that match what’s already on the roof. You get manufacturer-recognized materials and a written guarantee on every repair, included with every job. If a repair fails within 365 days, the second visit is free.
Common Roofing Company Problems We See in East Hemet Homes
- Wrong system quoted on manufactured homes. Crews that quote a standard asphalt-shingle re-roof on a low-slope HUD-code panel roof are quoting the wrong system and the wrong price. The roof can’t shed water the way a shingle roof does, and the shingles will fail early.
- Failed roof-to-wall connections on pre-1990s parks. The leading-edge fasteners on older manufactured homes in East Hemet corrode from decades of thermal cycling and Santa Ana wind uplift. Cracked sealant at that joint is the number one slow leak source we find.
- Overheated membranes and adhesives. Summers here regularly exceed 105°F. That cooks membrane adhesives and degrades underlayment and architectural shingles far faster than coastal Southern California, so valleys and penetrations need ice and water shield even though it never snows.
- Builder warranties voided by careless re-roofs. On newer master-planned tract homes in East Hemet, drilling through the deck or disturbing the ridge vent and starter strip without documented pre-inspection can void the builder warranty. We write a warranty-preserving scope before we touch anything.

FAQs About Roofing Company in East Hemet
Yes, but only if the roofer documents existing conditions before touching the deck and writes a scope that specifically preserves the ridge vent, starter strip, and deck attachments. We photograph everything, note existing conditions in the written quote, and avoid drilling through the deck wherever possible. The builder warranty stays intact because we never disturb what we don’t need to, and we prove it with the pre-inspection record. Call (743) 200-8347 for a warranty-safe re-roof quote.
Most manufactured homes in East Hemet have low-slope roofs, often 3/12 or lower, which is below the minimum slope where asphalt shingles actually shed water. Shingles on that slope trap water and fail within a few years. Elastomeric coating seals the metal panels, and TPO overlay handles the flat or ponding sections correctly. We’re out on these roofs every week, and the wrong-system re-roof is the most expensive mistake a homeowner here can make.
Most East Hemet tract homes run between 12 and 22 squares, and most manufactured homes run between 8 and 16 squares. A square is 100 square feet of roof area, and the number on the quote should match the roof’s actual measured planes, including overhangs. We measure on-site and show you the math in the written quote. If another bidder’s square count seems high or the price per square is hidden, ask to see the measurements.
Some will, some won’t, and the answer lives in your CC&Rs and architectural guidelines. Many East Hemet HOAs restrict material changes to those that match the original builder palette, so a standing-seam metal roof in a neighborhood built with architectural shingles may need written board approval. We can provide the material specifications and wind-rating documentation the HOA usually requests. The best first step is pulling your HOA’s architectural standards and bringing them to the estimate.
The wind rating matters less than the slope. On a tract home with a conventional pitch, we install shingles rated for the wind uplift the San Jacinto Valley experiences during Santa Ana events, and we use the manufacturer’s high-wind nailing pattern. On a low-slope manufactured home roof, the shingle rating is irrelevant because shingles are the wrong system entirely. That roof needs elastomeric coating or TPO, with the roof-to-wall connection addressed separately.
