Roofing Services We Provide in Mariposa
We handle the full range of residential roofing services for Mariposa homes, from a single leak to a complete system replacement. Exterior work is all we do, and that focus is deliberate. It means roofing done once, done right, with in-house crews who work on roofs every day rather than between other trades. Whatever your roofing needs, we scope them honestly.
Roof Repair & Leak Repairs
We fix leaks, reseal or replace flashing, and swap out missing or damaged shingles before a small opening becomes interior water damage. Because western Mariposa County gets most of its rain in winter, the time to address a worn valley or a loose penetration is before that wetter season arrives. When needed, our crews can perform temporary measures to stop active damage while we schedule the permanent fix. Single-issue repairs commonly run between $800 and $1,500, though an inspection confirms the real scope.
Roof Replacement & Full Replacement
A full roof replacement covers the complete system: tear off, decking inspection and repair, underlayment, flashing, ventilation, and a Class A assembly suited to wildfire-area rules. Because Mariposa County treats the entire county as Wildland-Urban Interface territory, the reroof certification addresses deck, slope, roof covering, flashing, gutters, WUI compliance, insulation, ice-barrier provisions, and applicable cool-roof standards. We build to that certification, not around it.
Roof Inspections
We perform roof inspections annually and after major storms, which is the right cadence for catching wear early. On older and historic Mariposa roofs, our roofers look closely at flashing details, prior roofing layers, ventilation, and decking condition that may not show from the ground. Our inspection and emergency response also cover immediate repairs when a storm leaves you exposed, and we clear any debris left behind.
Tile Roof, Metal, Asphalt & Flat Roofing Materials
We install asphalt shingle, tile, metal, and flat roofing, matched to local heat, UV exposure, and fire considerations. Asphalt shingles remain the most common material across the country and are a strong value choice. A tile roof can last well over 50 years with proper maintenance, and tile stands up to our intense summer sun. Metal handles severe weather and heat well. Flat and single-ply systems suit certain structures and outbuildings. The right system is the one suited to your roof’s conditions, not a one-size answer. We also install solar on roofs built to carry it, with sealed penetrations.
Commercial Roofing & Mobile Home Roofing
Mobile homes are a meaningful part of Mariposa’s housing, with a local profile reporting 122 mobile homes among roughly 826 housing units. We inspect and replace mobile home roofs with the same documented scope we bring to site-built houses. We also handle commercial roofing for local business properties and outbuildings, applying the same written-scope approach our residential customers rely on. For property owners who also need related exterior work, we can act as a general contractor on the broader scope.
Storm & Insurance Documentation
After wind or storm damage, we photograph and document the condition of your roof to support a homeowner’s insurance claim. We work with your insurance company through the process, but we never guarantee an outcome. The goal is clear, honest documentation that helps you and your adjuster see the same thing.

We serve Mariposa from our Fresno office, so distance never becomes an excuse for silence, and our team has decades of combined roofing experience behind each job.
California roofing contractors are required to carry general liability and workers’ compensation insurance, and a serious professional provides both a manufacturer material warranty and a workmanship warranty. We give you an itemized written estimate covering every part of the job, so you can read reviews and the rating of other roofing companies across multiple platforms and still find our paperwork matches what we promised. We strive to earn that trust on the first visit.

A Client Success Manager and a dedicated project manager coordinate your schedule, inspections, and any approvals, with clear check-ins so you are never left guessing. If a question comes up by phone, it gets answered; we aim to have a real person standing by rather than a message left ignored. We also have Spanish-speaking staff when that helps. That concierge approach comes straight from how we treat our own families.

How Our Mariposa Roofing Process Works
Our Mariposa process follows a simple, defined path from first call to final inspection, with a named project manager handling permits and a Client Success Manager keeping you updated.
- Free inspection and quote. We examine the roof, decking access, and conditions, then give you a written estimate that details scope, material brands, costs, and timelines. Nothing starts without that document in your hands.
- Permit and scheduling. We pull the required county permit for a major replacement and plan the work around weather, access, and material delivery. Mariposa County plan-checks non-engineered minor projects in roughly five to eight working days.
- Tear-off and system build. We remove the old roof, inspect and repair decking, then install underlayment, flashing, ventilation, and your Class A covering. A typical replacement takes one to five working days depending on size and conditions.
- Inspection. Reroofs are eligible for the county’s electronic inspection program when done by an accepted licensed contractor. Traditional inspections require at least 48 hours’ notice, and areas not on the county’s Tuesday or Thursday routes are inspected Monday, Wednesday, and Friday.
- Cleanup and walkthrough. We follow Mariposa County’s disposal guidance for asphalt, dimension lumber, and untreated wood shingles, clean the site, and walk the finished roof with you.
Urgent repairs can often be accommodated around the clock within 24 hours. For anything larger, the written estimate is your protection, and we stick to it. Ongoing maintenance keeps a sound roof sound for years.

Mariposa Roofing: Permits, Climate & Local Details
Roofing in Mariposa runs through Mariposa County, not a city department, and knowing that county system is what separates a prepared roofing contractor from a guess. Permits are issued by the Mariposa County Building Department at 5100 Bullion Street, and applications can be initiated through the county’s Development Services online permitting system.
The county’s April 24, 2025 fee schedule listed a $313 flat fee for “Re-Roof or Re-Side,” and an April 2026 report recorded one residential reroof with $335 in fees paid. Because these figures can change, we confirm the current amount and fold applicable permitting into your written scope, so there are no surprises on your invoice. What you pay is what the estimate said.
Two local requirements shape most projects. First, the entire county is Wildland-Urban Interface territory, so the reroof certification addresses Class A assembly, compliant flashing, and WUI provisions. Second, the reroof form requires an ice barrier for permitted work above 3,500 feet. The town of Mariposa sits around 2,000 feet, but outlying parcels using a Mariposa address can sit higher, so we check elevation by parcel rather than assume it.
If your home is in the historic downtown core, there is an added step. The Historic Design Review Overlay applies primarily to downtown Mariposa, and the county’s design-review application lists reroofing as exterior work subject to Planning Department review. The Mariposa Town Historic District is roughly bounded by Charles Street, 11th Street, Jones Street, and 4th Street, and the historic residential grid runs 2nd through 11th streets alongside Jessie, Bullion, Jones, and Old Highway 140. We coordinate that review with the building permit when it applies.
Housing age matters here. A 2020 to 2024 profile reports a median structure year of 1975 for Mariposa, and National Register records note that most buildings beyond 11th Street were built in the latter half of the 20th century, many in the 1940 to 1950 period. Older roofs are more likely to hide worn flashing, tired ventilation, or decking that only shows at tear-off, which is why our roofers inspect rather than promise.
Climate and terrain drive our scheduling. Summers are warm with strong sun that ages shingles and seals, while heavier winter rain tests flashing and drainage. Terrain shifts quickly around town, near Mariposa Creek, Stockton Creek Reservoir, the fairgrounds, high school, and hospital, so access and staging get planned ahead. Our crews reach town from our Fresno office by Highway 41 toward Oakhurst and Highway 49 north into the Mariposa area, and local supply runs through places like Coast Hardware at 5028 Highway 140 when we need something on short notice.

Frequently Asked Questions
Do I need a permit to replace my roof in Mariposa?
Yes. The Mariposa County Building Department at 5100 Bullion Street issues the reroof permit, and we pull it for you and include it in your written scope. Contractors are required to pull building permits for major roofing replacements, and California roofing work totaling $500 or more must be done by a licensed contractor. The county’s April 24, 2025 schedule listed a $313 flat “Re-Roof or Re-Side” fee, which we confirm before billing.
How much does a new roof cost in Mariposa?
There is no honest fixed price without an inspection, because cost depends on roof size, pitch, material, decking condition, and access. A new roof is not an expensive guess when the scope is written down first. Industry ranges for a full replacement often fall between $10,000 and $20,000, and inspections typically run $140 to $400 in California, but those are general figures, not your quote. Requesting multiple written estimates is the smart way to compare roofing companies fairly, and ours is free and itemized, so you can judge whether you are getting a great price for the quality.
Does my Mariposa roof need to be Class A for wildfire protection?
Yes, in practical terms. Mariposa County identifies the entire county as Wildland-Urban Interface territory, so the reroof certification addresses Class A assembly and WUI compliance. If your permitted work is above 3,500 feet, the reroof form also requires an ice barrier, which is one reason we verify your parcel’s elevation rather than assume it from the mailing address.
Can you reroof a home in Mariposa’s historic downtown district?
Yes, but exterior work in that area may need Planning Department design review in addition to the building permit, and we coordinate both. The Historic Design Review Overlay applies primarily to downtown Mariposa, within a district roughly bounded by Charles Street, 11th Street, Jones Street, and 4th Street. We confirm overlay status by parcel so the approvals line up before the crew arrives.
How long does a roof replacement take in Mariposa?
It depends on size, pitch, access, decking condition, material, weather, and inspection timing, so we don’t promise a fixed number. Most replacements take one to five working days once underway, and the county generally plan-checks non-engineered minor projects in about five to eight working days. Emergency repairs are handled far sooner, often within 24 hours, when you have an active leak.
Do you serve areas beyond Mariposa?
Our office is in Fresno, and we serve the wider region of the USA’s Central Valley and foothills, including communities like Madera, Clovis, Visalia, and Sanger, with occasional requests reaching toward San Jose. If you are outside the immediate Mariposa area and want to know whether we cover your city, send us a request or call and we will tell you plainly.
Do you charge extra to come from Fresno, and what if you find rotten decking?
Any travel handling is stated plainly in your written estimate, with no hidden line later. Our crews reach the Mariposa area from our Fresno office by Highway 41 and Highway 49, and that logistics planning happens before work begins. If we uncover rotten or damaged decking after tear-off, we photograph and document it, then get your authorization before any added work. Your itemized estimate spells out how concealed conditions are handled, so a surprise under the shingles never becomes a surprise on the bill.
