Preliminary roof budget
Budget Your Roof
Choose a Zenith product configuration, enter the home's living area and roof complexity, and receive a preliminary planning range.
Planning guidance: This is a preliminary budget range. Roof measurements, decking, extra layers, low-slope areas, access and concealed conditions can change the final proposal.
Choose complexity
Match the number of roof sections, pitch changes and access. This is a planning choice, not a satellite roof measurement.
Review the range
The widget provides a preliminary range using the selected Zenith Owens Corning configuration. It is not a contract price.
Confirm the scope
Zenith verifies roof area, decking, tear-off layers, flashings, ventilation, low-slope sections and warranty eligibility.

A practical starting comparison
Oakridge, Duration or Duration COOL?
The right answer depends on the property, current product data, design direction and applicable code path. Zenith confirms those details before the final specification.
Owens Corning
Oakridge
A value-focused architectural shingle and a step up from a traditional three-tab look. We compare the current regional palette, complete-system components and physical samples before ordering.
TruDefinition
Duration
A performance-focused architectural shingle featuring Owens Corning SureNail technology, a visible engineered fabric strip in the nailing area designed to support consistent fastening.
TruDefinition
Duration COOL
A California-only Duration Series option with SureNail technology and CRRC-rated solar-reflective choices. The exact product, color and active rating must fit the property's code path.
| Decision point | Oakridge | Duration | Duration COOL |
|---|---|---|---|
| Planning position | Value-focused architectural shingle | Performance-focused architectural shingle with SureNail technology | California cool-roof option with SureNail technology and solar-reflective choices |
| Color planning | Compare the current regional palette and physical samples | Compare the current regional palette and physical samples | Compare current COOL colors, physical samples and active product ratings |
| Cool-roof path | Verify whether the exact selected product, color and assembly fit the applicable code path. | CRRC-rated options offered for California cool-roof choices; the exact listing and project still control. | |
| What stays the same | Deck condition, roof slope, underlayment, flashing, ventilation, accessories and installation quality still determine the complete scope. | ||
Product features and regional availability can change. Confirm the specified product, color, current rating and accessory package in the written proposal. Review the official Duration Series comparison.
Owens Corning Total Protection Roofing System
Owens Corning Total Protection works in layers.
Owens Corning describes the Total Protection Roofing System as an integrated group of components designed to help a roof perform in three critical areas. Zenith still verifies the deck, slope, transitions and attic before specifying the final assembly.
Help keep moisture away from the roof deck
- Ice and water barrier at vulnerable areas
- Synthetic underlayment beneath the shingles
Build the protective shingle assembly
- Starter shingles at eaves and rakes
- Field shingles plus matching hip and ridge shingles
Plan balanced attic ventilation
- Intake ventilation that allows outside air to enter
- Exhaust ventilation that helps release heat and moisture
Important system distinction: Owens Corning states that non-Owens Corning items such as flashing, fasteners, pipe boots and wood decking are excluded from the branded Total Protection Roofing System. Zenith still inspects and specifies those roof-critical details separately. Read the official system overview.
How Zenith turns the manufacturer system into a roof-specific scope
Inspect the deck
Open the roof, document concealed conditions and correct the nailing surface where the approved scope requires it.
Protect transitions
Specify compatible underlayment and focused protection at eaves, walls, chimneys, valleys and penetrations.
Build the shingle field
Coordinate starter, field shingles, hip and ridge products, drip edge and flashing as one installation.
Balance ventilation
Evaluate intake and exhaust for the actual attic instead of prescribing one vent type for every property.

Online tools help with planning. These four checkpoints show what our crew verifies, installs and documents at the property.
California cool-roof guidance
Does Title 24 require a cool roof for my property?
It depends. For permit applications submitted on or after January 1, 2026, California's 2025 Energy Code applies. The correct path still depends on climate zone, building type, roof slope, project scope and applicable exceptions. A product name by itself does not settle compliance.
Manufacturer protection option
The exact protection level and eligibility are confirmed in the written Zenith proposal.
Owens Corning Preferred Contractor warranty options
Which Owens Corning warranty is included?
Zenith can offer eligible Owens Corning System Protection and Preferred Protection limited warranties as a Preferred Contractor. Coverage is not automatic. It depends on the selected shingles, qualifying components, installation requirements and registration, so the proposal must identify the exact protection level.
- Named shingles and accessories
- Manufacturer protection level
- Zenith workmanship coverage
- Registration and closeout documents
50-year Owens Corning warranty guidance
Standard, System Protection and Preferred Protection compared.
This plain-language comparison separates product-defect coverage, contractor-workmanship coverage and qualifying component requirements before the roof inspection.
Direct answer
What is the Owens Corning 50-year warranty? Owens Corning's current comparison lists a 50-year TRU PROtection period for qualifying System Protection and Preferred Protection roofing systems. Preferred Protection also lists workmanship coverage for the first 10 years. These are different coverage categories, and the actual warranty document controls.
Standard Product Limited Warranty
10-year TRU PROtection periodCurrent limited-lifetime product coverage for eligible shingles. It does not list contractor workmanship coverage.
- Does not require Preferred Contractor status
- Component coverage remains subject to current requirements and the actual warranty terms
System Protection Limited Warranty
50-year TRU PROtection periodExtended manufacturing-defect protection for a qualifying Owens Corning roofing system. It does not list workmanship coverage.
- Installed by an Owens Corning Preferred or Platinum Contractor
- Generally requires qualifying hip and ridge shingles plus two other Owens Corning accessories
Preferred Protection Limited Warranty
50-year TRU PROtection plus 10-year workmanshipCombines the qualifying 50-year manufacturing-defect protection period with workmanship coverage for the first 10 years.
- Installed by an Owens Corning Preferred or Platinum Contractor
- Generally requires hip and ridge shingles, underlayment and two additional qualifying Owens Corning accessories
TRU PROtection is the initial enhanced coverage period.
Owens Corning explains that this initial period includes labor cost to repair or replace qualifying defective materials. The exact shingle, components, structure type, limitations and warranty terms determine coverage.
Keep the roof details documented.
Owens Corning currently requests the installation date, shingle type, shingle color and installed squares for registration. Zenith's closeout identifies the installed products and warranty submitted for the project.
Second-owner timing matters.
Owens Corning currently states that transfer to a second owner must be initiated within 60 days of the real-estate transfer and may require supporting documents and a fee.
Reviewed August 14, 2026. Product and warranty requirements can change. See the actual warranty for complete details, limitations and requirements.

Direct answers before the estimate
Owens Corning roofing answers.
Clear, source-informed guidance reviewed for Zenith by Bryan Ramirez, roofing contractor and company principal. CSLB C-39 #1036112.
Is Zenith Roofing Services an Owens Corning Preferred Contractor?
Yes. Zenith Roofing Services is an Owens Corning Preferred Contractor and a California C-39 roofing contractor, CSLB #1036112. Enhanced manufacturer protection depends on the selected system, qualifying components, installation requirements and registration.
What does Owens Corning Preferred Contractor mean?
Owens Corning describes Preferred Contractors as independent contractors who meet its requirements for professionalism and reliability. Current program requirements include applicable licensing and insurance, at least $1 million in general liability insurance, and approved business credit. Preferred Contractors may offer eligible System Protection and Preferred Protection limited warranties.
What is the Owens Corning 50-year warranty?
Owens Corning's current warranty comparison lists a 50-year TRU PROtection period for qualifying System Protection and Preferred Protection roofing systems. Preferred Protection also lists workmanship coverage for the first 10 years. The actual warranty document, installed products and registration control coverage.
What is the difference between System Protection and Preferred Protection?
Both current extended options list a 50-year TRU PROtection period for qualifying systems. System Protection does not list workmanship coverage and generally requires Owens Corning hip and ridge shingles plus two other qualifying accessories. Preferred Protection lists 10 years of workmanship coverage and generally requires hip and ridge shingles, underlayment and two additional qualifying accessories.
What components are required for Preferred Protection?
Owens Corning currently identifies four qualifying roofing components for Preferred Protection: Owens Corning hip and ridge shingles, Owens Corning underlayment and two additional qualifying Owens Corning accessories. Eligibility must be confirmed for the specific roof and documented in the proposal.
Is the Total Protection Roofing System the same as a warranty?
No. Total Protection describes the integrated SEAL, DEFEND and BREATHE roofing-system approach. A warranty is a separate legal document with its own product, contractor, installation and registration requirements.
Which Owens Corning shingles does Zenith install?
Zenith installs Owens Corning Oakridge, TruDefinition Duration and Duration COOL architectural shingle systems when they fit the roof, design goals and applicable requirements. Product availability, color, roof slope, ventilation and accessories are confirmed in the proposal.
Does every California reroof require a Title 24 cool roof?
No single answer applies to every roof. The current energy-code path depends on permit date, climate zone, building type, roof slope, project scope and applicable exceptions. Zenith verifies the jurisdiction and specified product rating before recommending a cool-roof assembly.
Can Budget Your Roof provide a final roof price?
No. It provides a preliminary planning range. It cannot see concealed layers, damaged decking, flashing conditions, low-slope areas, ventilation or access constraints. A final Zenith proposal requires roof measurements and an inspection.
What should a homeowner do before replacing a roof?
Document roof concerns and warning signs, compare products and colors, review the complete written scope and warranty options, prepare the property for installation, and keep the final registration and closeout records.
What is included in a complete Owens Corning roof system?
A complete roof is more than visible shingles. The specified assembly can include deck correction, underlayment, leak protection, drip edge, starter, field shingles, hip and ridge shingles, flashing and balanced ventilation. The proposal should list the exact components.
What information is needed to register a warranty?
Owens Corning currently lists the installation date, shingle type, shingle color and number of installed roofing squares among the information needed for registration. Zenith supplies applicable closeout documents for the warranty included in the contract.
Can an Owens Corning roof warranty transfer to a new owner?
Owens Corning currently states that transfer to the second owner must be initiated within 60 days of the real-estate transfer. Supporting documents and a fee may apply under the warranty in effect at installation.
