How it works
Your Modesto apartment building roof project in four steps.
Modesto Portfolio Inspection
We walk every building, drone every roof, and deliver a written asset report covering remaining useful life, deck condition, and code gaps. Free for Modesto portfolios of any size.
CapEx Plan
You receive a flat-bid proposal per building plus a per-door cost breakdown sized for the Modesto market. We sequence the work to fit your reserve study and protect NOI through your hold period.
Tenant Notification
14-day, 7-day, and day-before notices in English and Spanish. We coordinate with your property manager on Modesto noise-ordinance hours, balcony access, and pet/vehicle protection.
Phased Modesto Install
Building-by-building schedule. Same-day tear-off and dry-in before tule fog rolls in. Magnetic sweep every evening. No Modesto tenant ever sleeps under an open roof.
Built for occupied Modesto buildings
Built for occupied Modesto buildings.
A Modesto multi-family roof project is a tenant experience, not just a construction project. Every disruption is a phone call to your property manager. We engineer those calls out.
Tenant disruption planning
Bilingual notices, designated quiet hours that match City of Modesto noise ordinance, and protected balconies. Property managers get a single point of contact — our project manager — for the entire Modesto job. Tenants stay informed, and your office phone stays quiet.
Evening & weekend work
When lease provisions and Modesto noise ordinance allow, we run finish work after hours. Tear-off stays in noise-allowed daytime windows. Heat welding, edge metal, and clean-up shift to evenings to compress total disruption on your Modesto building.
Phased install schedule
We sequence buildings so your Modesto leases stay marketable through the project. Vacant unit turns get prioritized. Move-in dates get protected. We coordinate with your leasing team on showings along McHenry, Briggsmore, and the College Area.
Warranty tier
The highest warranty tier — backed in writing for your Modesto portfolio.
As an Owens Corning Platinum Preferred, GAF Master Elite, and CertainTeed Select ShingleMaster contractor, we register the highest manufacturer warranties available on every Modesto multi-family job. That matters more for apartment owners than for single-family because warranties travel with the asset at sale.
- GAF Golden Pledge — 50-year material coverage, 25-year workmanship coverage, transferable once at sale. Standard on Modesto asphalt low-rise apartment buildings.
- OC Platinum Protection — non-prorated lifetime materials and workmanship, transferable. Available on qualifying Modesto garden-style complexes.
- 20-30 year NDL TPO — No Dollar Limit manufacturer warranties on low-slope Modesto buildings (Carlisle SynTec, GAF EverGuard, Firestone UltraPly).
- Econo Roofing workmanship — 5-10 year transferable workmanship warranty layered on top, covering install defects the manufacturer warranty does not.
Your buyer's broker, lender, and inspector all get a clean warranty package at sale. That protects exit cap rate and shortens diligence on Modesto trades. Read our complete roof warranty guide to compare manufacturers.
When to act
Signs your Modesto apartment building's roof needs replacement.
Catch these early and you preserve NOI. Miss them, and a Modesto tenant complaint becomes a habitability claim under California Civil Code 1941.1.
Repeat tenant leak calls
The same unit calls in a leak after every Modesto storm. That is not a flashing problem. That is a system at end of life.
Granule loss in gutters
Heavy mineral-granule deposits at downspouts mean asphalt shingles are 15+ years in. Plan replacement before the next Stanislaus County rainy season.
Ponding on flat sections
Standing water 48 hours after a storm on a low-slope Modesto carport or clubhouse indicates drainage failure. The membrane below is degrading fast.
Interior ceiling stains
Brown rings on a Modesto tenant's ceiling are a habitability red flag. Document and repair within 30 days or risk a CA Civil Code 1941.1 claim.
Rising HVAC costs
Modesto summers run 100°F+ for weeks. Underperforming insulation drives cooling costs hard. A Title 24 cool-roof upgrade often pays back within the hold period.
Roof age 18+ years
Most asphalt apartment roofs in the Modesto climate reach end of life around 18-22 years. Plan replacement at year 18 to avoid emergency calls.

Frequently asked
Common Modesto multi-family roofing questions, answered.
How do you minimize tenant disruption during a Modesto multi-family re-roof?
For Modesto apartment buildings, we build a written tenant communication plan before mobilization. Residents receive 14-day, 7-day, and day-before notices in English and Spanish. We schedule loud tear-off for daytime weekday windows that align with City of Modesto noise ordinance hours and your lease's quiet hours. Work is phased building-by-building so no Modesto tenant lives under an open roof. Evening and weekend finish work is available when lease provisions and the local ordinance allow.
What does multi-family roofing cost per door in Modesto, CA?
For a typical Modesto garden-style complex along the McHenry or Briggsmore corridors, expect $1,800-$3,800 per door for asphalt re-roofs and $3,500-$6,500 per door for TPO or modified bitumen on low-slope buildings. A 60-unit Modesto complex usually lands $140,000-$320,000 depending on slope, deck condition, Title 24 cool-roof upgrades for our 100°F summers, and whether you bundle gutters and skylights. We provide flat-bid pricing per building and per door.
How long do City of Modesto building permits take for a multi-family re-roof?
City of Modesto Building Division typically issues over-the-counter re-roof permits in 1-3 business days for straightforward like-for-like replacements. Plan-check submittals for structural deck work, ventilation upgrades, or Title 24 cool-roof compliance on larger garden-style complexes can run 2-4 weeks. We pull the permit, schedule the in-progress and final inspections, and deliver the closed permit to your file as part of the close-out package.
Do you handle CapEx planning and reserve studies for Modesto portfolios?
Yes. For Modesto investors and Stanislaus County syndication GPs, we provide a roof asset report covering remaining useful life per building, estimated replacement cost, and a recommended capex schedule. This integrates with your reserve study or business plan and helps you protect NOI by phasing replacements across your hold period instead of taking one large hit during a Modesto leasing season.
Can you work around occupied Modesto apartment buildings without relocating tenants?
Yes. We have re-roofed Modesto apartment communities from 8-unit College Area walk-ups to 240-unit Briggsmore corridor garden-style complexes without a single tenant relocation. Crews protect balconies, walkways, and patios. We sweep magnetically every evening so kids, pets, and tires stay safe. Modesto tenants stay in their units throughout the project.
What warranties do you offer on Modesto multi-family roofs?
As OC Platinum Preferred and GAF Master Elite contractors serving Modesto and Stanislaus County, we register the highest warranty tier available. For asphalt low-rise: GAF Golden Pledge (50-year materials, 25-year workmanship). For low-slope TPO: 20-30 year No Dollar Limit (NDL) manufacturer warranties. Workmanship warranties from Econo Roofing run 5-10 years and are transferable to a new buyer at sale, which protects your Modesto asset's marketability.
How does Modesto's tule fog and 100°F summer climate affect apartment roof life?
Modesto's combination of 320+ UV days, 100°F+ summers, and winter tule fog cycles is hard on apartment roof systems. UV degrades asphalt granules, summer heat thermally cycles flat membranes, and fog moisture exploits any flashing weakness. Most asphalt apartment roofs in Modesto reach end of life around 18-22 years, slightly earlier than coastal California. Title 24 cool-roof upgrades and ENERGY STAR-rated TPO membranes pay back faster here than almost anywhere in the state.
Overview
About Modesto multi-family roofing.
Modesto multi-family roofing covers any Stanislaus County property with five or more rental units under common ownership: garden-style apartments off McHenry and Briggsmore, 9th Street historic walk-ups, College Area townhome rentals, mixed-use podium buildings downtown, condo conversions, and small portfolios of duplexes and fourplexes scattered across the city. The work is technically similar to commercial roofing — TPO and modified bitumen on low-slope sections, asphalt and tile on pitched sections — but the operational reality is fundamentally different. You are not roofing an empty warehouse on Yosemite Boulevard. You are roofing 60 households who pay your debt service every month.
That changes how a real Modesto multi-family contractor scopes the job. The technical install is maybe 40% of what we do. The other 60% is tenant communication, lease compliance, balcony and vehicle protection, daily magnetic sweeps, vacant-unit prioritization, and phased mobilization that lets you keep marketing the property while crews are on site. A contractor who treats a Modesto apartment roof like a single-family roof — show up Monday, tear off, install, leave Friday — will generate enough tenant complaints to wipe out a quarter of NOI.
We have been roofing apartment buildings across Modesto, Turlock, Ceres, Riverbank, Oakdale, and the rest of Stanislaus County since 1996. Owners come back to us for the second, third, and fourth Modesto building because the project actually does close on time and on budget, and tenant calls actually do stay under control.

Our approach
How we approach Modesto multi-family replacements.
Per-door capex calculation
We deliver pricing both as a total project number and as a cost-per-door figure. That second number is what your investor letter, reserve study, and underwriting model actually need. We benchmark against comparable Modesto and Stanislaus County properties so you know if your scope is in line with the market.
Tenant comms package
You get a written communication plan, a draft 14-day notice in English and Spanish, FAQ language for your Modesto leasing office, and a single project manager phone number tenants and your property manager can call. We handle the calls so you do not have to.
Lease & ordinance compliance
Before mobilization we review your standard lease and Modesto's noise ordinance for quiet hours, balcony access provisions, and 24-hour notice requirements. If your lease says quiet hours start at 8pm, we are off the roof at 7:45. If it requires 24 hours' notice for balcony access, we deliver 48.
Phased install execution
We sequence buildings to minimize impact on Modesto leasing velocity. Vacant units get prioritized so they hit market with fresh roofs. Move-in dates get protected. Showings get scheduled around our work, not the other way around.

Read before you decide
Read before you sign a Modesto roof contract.
Three things every Modesto apartment owner should understand before signing a multi-family roof contract.
Tenant rights and CA Civil Code 1941.1
California habitability law requires landlords to maintain "weatherproofing" — including the roof. A documented active leak with a delayed repair becomes legal exposure fast on a Modesto property. Document every tenant leak call in writing, schedule the repair within 30 days, and keep photos. Our claim documentation guide covers the paper trail.
Lease provisions about access and noise
Your standard Modesto lease almost certainly defines quiet hours, balcony access notice, and parking. The City of Modesto noise ordinance also caps construction hours. Read those clauses before scheduling work. A contractor who breaches them creates lease-violation exposure for you, not them. We review your lease as part of mobilization.
CapEx vs OpEx classification
Full Modesto roof replacements are typically capitalized and depreciated. Routine repairs may qualify as OpEx under IRS safe harbors. The classification affects your tax basis, depreciation schedule, and 1031 exchange planning on your next Stanislaus County trade. We provide line-item proposals so your CPA can categorize. We are not tax advisors.
When to call
When to call us for your Modesto multi-family roof.
Most Modesto apartment owners call us in one of four moments. Each gets a different scope.
- Pre-acquisition diligence. You are under contract on a 40-unit Modesto building and need a roof condition report inside the inspection period. We turn these in 48-72 hours with photos, remaining-life estimates, and replacement cost ranges your underwriter can plug into the model.
- Annual capex planning. Q4 budget season. You need replacement cost estimates for Modesto buildings flagged in last year's reserve study. We deliver written per-door pricing your asset manager can drop into the model.
- Active leak emergency. A Modesto tenant called in a leak this morning. We dispatch a tarp crew within 4 hours, document for insurance, and follow up with a permanent repair scope by end of week.
- End-of-hold disposition. You are listing the Modesto property and the buyer's inspector flagged the roof. We provide a written replacement quote and timeline so you can negotiate the credit or schedule the work pre-close.
Whatever the trigger, the first call is free, and the written report is yours to keep regardless of whether you hire us. Reach the Modesto multi-family team directly at (209) 668-6222.
Materials & systems
Materials & systems for Modesto apartment buildings.
We match the system to the building type, your hold period, and the Modesto climate. Most local 1970s-1990s garden-style complexes get a hybrid: asphalt or tile on pitched roofs, TPO or modified bitumen on flat carport and clubhouse sections.
TPO (Thermoplastic Polyolefin)
Highly reflective white membrane. Ideal for Modesto low-slope apartment buildings, carports, and clubhouses where Title 24 cool-roof compliance and 100°F summer cooling costs matter. 20-30 year NDL warranties. Heat-welded seams.
Modified Bitumen
Multi-layer asphalt system with strong puncture resistance. Excellent choice for Modesto buildings with rooftop HVAC, foot traffic, or solar. 15-20 year service life. Self-adhered or torch-applied.
EPDM (Rubber)
Proven 50-year track record on low-slope multi-family. Cost-efficient for large flat areas common on Briggsmore-corridor complexes. Very low maintenance. Good fit for mid-hold Modesto portfolios where reliability matters more than reflectivity.
Asphalt for low-rise
For Modesto's typical 2-3 story garden-style apartments with pitched roofs, architectural asphalt shingles deliver the best price-per-door. GAF Timberline HDZ with Golden Pledge warranty is our default spec.
Compare options on our dedicated Modesto pages: flat roofing, metal roofing, and tile roofing. For sloped buildings, see Modesto roof replacement.
Process & timeline
What to expect — our Modesto multi-family roofing process.
Modesto portfolio inspection & capex report
We walk every building, drone every roof, and core-sample suspect low-slope sections. Within 5 business days you receive a written roof asset report covering remaining useful life, deck condition, ventilation, and code gaps. Per-building replacement budgets sized for the Modesto market are included.
Tenant communication plan
14-day, 7-day, and day-before notices delivered in English and Spanish. We coordinate with your property manager on Modesto noise-ordinance hours, balcony access, and pet/vehicle protection. Our project manager becomes the single tenant point-of-contact.
City of Modesto permit & phased mobilization
We pull the permit from City of Modesto Building Division — typically 1-3 days. Crews then sequence work building-by-building. We protect cars with tarps, balconies with plywood, and walkways with cones. Materials stage off lease-paths and away from tenant entries.
Tear-off and dry-in same day
We strip the existing roof and dry-in with synthetic underlayment before crews leave the site. No Modesto tenant ever sleeps under an open roof. Active weather forecast — including winter tule fog moisture — triggers a hold-the-line stop.
Install new system & flashings
Shingles, TPO, or modified bitumen installed to manufacturer spec. Re-flash all penetrations, valleys, and parapet walls. Upgrade ventilation to current code. Photograph every detail for your warranty file.
Final walk, magnetic sweep & warranty register
Walk every roof with the owner or property manager. Magnetic sweep all common areas, parking lots, and tenant patios across the Modesto property. Register manufacturer warranty within 30 days. Deliver transferable workmanship warranty with the close-out package.
Typical 60-unit Modesto complex: 14-21 working days. Larger Stanislaus County portfolios are scheduled across 2-4 month windows to align with leasing seasons. Read the full inspection process guide.
Cost
Multi-family roofing cost in Modesto, CA.
Modesto multi-family pricing is most useful expressed per door. That number plugs into your underwriting model and reserve study directly.
- Asphalt re-roof, 2-3 story Modesto garden-style: $1,800-$3,800 per door. A 60-unit Modesto complex usually lands $108,000-$228,000.
- TPO low-slope, mid-rise Modesto apartment: $3,500-$6,500 per door. A 100-unit Modesto mid-rise commonly runs $350,000-$650,000.
- Modified bitumen on carport & clubhouse: $8-$15 per square foot. Typical 12,000 sq ft Modesto carport project: $95,000-$180,000.
- Title 24 cool-roof upgrade: $0.40-$1.20 per square foot incremental. Often pays back in HVAC savings within 4-7 years given Modesto's 100°F+ summers and 320+ UV days.
- Tile re-roof, premium Modesto garden-style: $4,500-$8,500 per door. Concrete tile, 50-year material life.
We provide flat-bid pricing per building and per door, accept commercial financing through approved lenders, and structure progress payments to align with phased install milestones.

Why Modesto apartment owners choose us.

"We re-roofed a 96-unit garden-style complex off Briggsmore with Econo over six weeks. Zero tenant relocations, zero habitability complaints, and the per-door number matched the proposal exactly. Mario's team handled the bilingual notices for us."
"As a syndication GP I needed a written capex report that my LPs could review. Econo turned it around in four business days for a 240-door Modesto asset and stayed accurate to within 3% on the actual install. Re-hired them on building two."
"Our property manager was nervous about disruption on a 48-unit College Area building during peak leasing. Econo phased the work around our showings, swept the parking lot every night, and we leased two new units while crews were on site."
A note from Mario

Every Modesto project gets a tenant communication plan, evening/weekend work options, and a phased install schedule designed to keep your building leased and your NOI protected through California's hottest summer days."
