What Roof Replacement Should Include: A Homeowner Scope Checklist

What Roof Replacement Should Include

A roof replacement should be written as a scope of work, not as a vague promise to install a new roof. Homeowners should be able to see what will be removed, what will be inspected, what will be installed, what may change after tear-off, who is responsible for permits and cleanup, and what records will be handed over when the job is complete.

The raw question is simple: what is included in roof replacement for homeowners? The useful answer is more specific. A complete roof replacement scope usually covers tear-off or approved re-cover work, deck inspection, damaged deck repair terms, underlayment, drip edge or edge metal where required, flashing details, roof covering installation, ventilation and penetration treatment, debris control, final inspection, warranty paperwork, and a clear record of what changed during the job.

That does not mean every house needs the same materials or the same sequence. The International Residential Code roof-assembly chapter explains that roof assemblies include the deck, substrate or thermal barrier, insulation, vapor retarder, roof covering, and other weather-exposed parts, and it says materials and methods used for replacing or re-covering an existing roof covering must comply with that chapter: https://codes.iccsafe.org/content/IRC2024P2/chapter-9-roof-assemblies. Local amendments, product instructions, roof slope, climate, and existing conditions can change the final requirement.

The homeowner's job is not to design the roof system. The homeowner's job is to make sure the written proposal names the major pieces, identifies the decision points, and leaves a clean paper trail.

Start With the Written Scope

The written scope should tell you whether the contractor is proposing a full tear-off, a re-cover over existing material, or a partial replacement tied to a specific roof section. Those are different projects. NRCA's homeowner resources describe two reroofing options: complete replacement, which removes the existing roof, and re-cover, which installs new roofing over existing roofing where allowed: https://www.nrca.net/roofing-guidelines/resources.

For most homeowners, the written scope should answer these questions before work starts:

• Which roof sections are included?
• Are old shingles, underlayment, nails, flashing, vents, and accessories being removed or reused?
• How will the contractor inspect the deck after tear-off?
• What happens if rotten, delaminated, soft, or broken decking is found?
• Which underlayment, starter, field shingle, ridge material, and accessories are being installed?
• Which flashings, pipe boots, vents, skylight details, chimney details, wall intersections, and valley details are included?
• Who obtains permits and schedules required inspections?
• How will plants, siding, windows, gutters, driveways, attic contents, and neighboring property be protected?
• What cleanup, magnetic nail sweep, haul-off, and final walkthrough are included?
• Which manufacturer, workmanship, and transferable warranty documents will be provided?

If the proposal only says "replace roof," ask for a clearer scope. The Federal Trade Commission advises homeowners to check contractors before committing, get written contracts, read them carefully, and avoid red flags such as large cash demands or pressure tactics: https://consumer.ftc.gov/articles/how-avoid-home-improvement-scam. That advice applies especially well to roof replacement because many important decisions are hidden until the old roof is opened.

Tear-Off, Re-Cover, and Deck Inspection

Tear-off means the existing roof covering is removed so the contractor can inspect what is underneath. Re-cover means a new covering is installed over an existing covering where that approach is allowed and appropriate. A homeowner should not assume re-cover is allowed just because it is cheaper or faster. Code requirements, existing layers, deck condition, material type, manufacturer instructions, and local inspection rules matter.

The deck is one of the most important scope items because it is also one of the easiest items to understate. A proposal should say whether deck replacement is included only as an allowance, included up to a named quantity, priced by sheet or linear foot after discovery, or handled through written change approval. It should also define how approval will happen: photo, description, unit price, homeowner authorization, and final invoice record.

A strong deck clause avoids two bad outcomes. The first is a surprise bill with no clear evidence. The second is a rushed decision where damaged decking is covered because no one agreed on a process. RoofPredict records can help homeowners keep before, during, and after photos tied to the property record, but the contractor still needs to document what was opened and what was replaced.

Ask for deck photos before the new underlayment covers the surface. Useful photos show the roof section, the damaged area, any removed material, and the repaired area. For larger jobs, ask the contractor to mark changed areas on a simple roof sketch or work order note. The goal is not to micromanage the crew. The goal is to preserve a clear record of what changed after tear-off.

Underlayment, Edge Details, and Roof Covering

Underlayment is the layer installed over the deck and below the roof covering. It is part of the water-shedding system, but it is not a magic substitute for correct roof covering, flashing, slope, ventilation, or drainage. The written scope should name the underlayment type, where self-adhered membrane will be used if required or selected, and how valleys, eaves, rakes, penetrations, and low-slope transitions will be treated.

Edge details matter because water, wind, and debris often attack roof edges first. The scope should say whether drip edge or other edge metal is included, where it will be installed, and whether gutter removal, gutter reset, or gutter protection is included. If gutters are staying in place, ask how the crew will protect them and how edge installation will be handled around them.

The roof covering section should name the material family and product line without relying on shorthand. For asphalt shingles, the scope should include starter, field shingles, hip and ridge material, fasteners, and related accessories. ARMA explains that proper nailing is essential for asphalt shingle performance and that manufacturer instructions and applicable codes should be followed: https://www.asphaltroofing.org/nail-application-of-asphalt-strip-shingles-for-new-and-recover-roofing/.

Do not let the proposal stop at color and brand. Color matters, but performance depends on the roof system being installed correctly for that house. If a contractor says a product choice changes ventilation, deck repair, warranty, high-wind details, impact resistance, energy performance, or maintenance obligations, ask for the manufacturer document or code reference behind that statement.

Flashing, Penetrations, and Ventilation

Flashing is where many scope disputes start. Chimneys, sidewalls, headwalls, skylights, valleys, pipe penetrations, vents, dormers, and roof-to-wall intersections should be named in the written scope. The proposal should say whether flashing will be replaced, reused, inspected and repaired as needed, or excluded. Reusing flashing may be acceptable in some cases and risky in others; the important point is that the decision should be visible before the job starts.

The ICC roof-assembly chapter includes flashing provisions for roof intersections, slope changes, and roof openings. IBHS also summarizes that building codes set minimum roof assembly requirements and that code focus areas include weather protection, structural performance, materials, and installation: https://ibhs.org/guidance/ricowi-roof-guide-codes-and-standards/. Homeowners do not need to memorize the code. They do need to ask whether the proposal addresses the vulnerable places where water usually enters.

Ventilation should be handled with the same care. A roof replacement can involve ridge vents, box vents, powered vents, soffit intake, bath fan terminations, kitchen exhaust, dryer exhaust, or attic airflow issues. The written scope should say which vents are being installed, replaced, removed, or left alone. It should also identify any ventilation issue that is outside the roofing contractor's scope but visible during the project.

Penetrations deserve their own review. Pipe boots, satellite mounts, abandoned brackets, solar standoffs, skylights, and older vents can become leak points if they are ignored. Ask the contractor to identify what will be removed, reset, replaced, sealed, or excluded. If solar panels, HVAC equipment, masonry, or electrical work is involved, the scope should identify who owns that coordination.

Cleanup, Protection, and Daily Job Control

Roof replacement is loud and messy. A professional scope should still make the job predictable. Homeowners should know where materials will be staged, where debris will fall, whether a dumpster or trailer will be used, how driveways and landscaping will be protected, and how the contractor will handle weather exposure if the roof cannot be closed in one day.

Daily job control matters most when the project spans several days or when weather interrupts the work. Ask who will be your point of contact, how schedule changes will be communicated, and what happens if uncovered areas need temporary protection. Avoid any wording that suggests the contractor can open more roof than the crew can reasonably protect.

Cleanup should be more specific than "leave clean." Ask whether the contractor includes debris haul-off, magnetic nail sweep, gutter cleaning related to roofing debris, attic debris checks where accessible, driveway and lawn checks, and removal of leftover materials. If you have pets, children, a shared driveway, or close neighbors, tell the contractor before work starts.

The handoff should also be named. At the end, a homeowner should receive the final invoice, warranty instructions, product information, permit or inspection proof where applicable, photos or notes for deck repairs, and a list of any excluded or unresolved conditions. If an issue was discovered but not repaired because it involved masonry, carpentry, insulation, electrical, or ventilation work outside the roof scope, that should be documented.

Choices That Are Usually Outside the Base Price

Many roof replacement disputes happen because the homeowner thought an item was included and the contractor treated it as extra. The exact contract controls, but homeowners should pay close attention to these possible add-ons:

• Decking, fascia, rafter tail, or structural repairs discovered after tear-off
• Chimney repair, chase cover replacement, or masonry work
• Skylight replacement, solar removal and reset, or specialty equipment coordination
• Gutter replacement, gutter guard removal, or downspout changes
• Attic ventilation corrections beyond simple vent replacement
• Interior stain repair, insulation work, mold remediation, or electrical work
• Permit fees, HOA forms, engineering letters, or special local inspection requirements
• Upgraded underlayment, impact-rated material, cool-roof material, designer colors, or special-order products
• Extra protection requirements for pools, delicate landscaping, shared driveways, or steep access

ENERGY STAR explains that cool roofs use solar reflectance and thermal emittance to help roofs stay cooler: https://www.energystar.gov/products/cool-roofs. That is useful selection context, but it should not be turned into an unsupported promise about utility bills, comfort, tax treatment, or payback. If a contractor sells an upgrade based on energy, wind, hail, fire, insurance, or resale claims, ask for the specific product documentation and any local program requirements.

The same principle applies to warranties. A manufacturer warranty, a workmanship promise, and a contractor service policy are different documents. Ask what is covered, who backs it, what can void it, whether registration is required, whether transfer is possible, and what maintenance is expected.

How to Compare Roof Replacement Scopes

When comparing proposals, line up scope items before comparing totals. A lower bid may be cheaper because it excludes flashing, permits, deck repair, disposal, ventilation work, cleanup, or warranty handling. A higher bid may be clearer because it includes those items. The only way to know is to compare what is actually written.

Use a simple comparison table:

• Tear-off or re-cover approach
• Deck inspection and deck repair pricing
• Underlayment and edge details
• Flashing replacement or reuse
• Ventilation and penetration handling
• Material line and accessory package
• Permit and inspection responsibility
• Property protection and cleanup
• Change-order process
• Warranty and handoff records

Ask each contractor to clarify vague language in writing. If a contractor will not define the scope, will not identify the product system, will not explain change-order pricing, or pressures you to sign before you understand the terms, pause. The FTC's Cooling-Off Rule may apply to certain sales made at a home or temporary location, but it does not cover every transaction: https://consumer.ftc.gov/articles/buyers-remorse-ftcs-cooling-rule-may-help. Homeowners should understand cancellation terms before signing instead of assuming they can unwind the agreement later.

RoofPredict can help keep the comparison organized by storing roof photos, property context, contractor notes, report status, and follow-up tasks in one record: https://www.roofpredict.com/. It does not replace a contractor's professional inspection or local code review. It helps homeowners keep the project facts from getting scattered across texts, emails, photos, and paper estimates.

A Practical Homeowner Checklist

Before signing, ask for a written scope that covers the roof sections included, roof removal approach, deck inspection process, deck repair pricing, underlayment, flashing, ventilation, penetrations, edge details, cleanup, warranties, and final documentation.

Before work starts, move vehicles, patio items, fragile planters, and attic valuables away from work areas. Confirm driveway access, material staging, pets, gates, sprinkler heads, satellite equipment, solar equipment, and neighborhood restrictions. Confirm who is responsible for permits, HOA notices, and inspection scheduling.

During work, ask for photos of opened roof areas, especially deck repairs and flashing conditions. Keep change approvals in writing. If the crew discovers something outside the original scope, ask whether it is urgent, whether the roof can be made weather-tight, and whether another trade or official inspection is needed.

At completion, walk the exterior with the contractor. Look at shingles, ridge details, valleys, wall intersections, penetrations, gutters, siding, windows, landscaping, driveway, and cleanup areas from the ground. Do not climb on the roof unless you are trained and equipped to do so. Ask for final photos, warranty instructions, product documents, permit or inspection records where applicable, and a summary of any unresolved conditions.

A good roof replacement should leave you with more than a new roof covering. It should leave you with a clear record of what was removed, what was found, what was installed, what was excluded, and who to contact if a problem appears.

Frequently Asked Questions

Does roof replacement always include new decking?

No. Many roof replacements include deck inspection, not full deck replacement. Damaged or unsuitable decking may be repaired or replaced after tear-off, but the proposal should define how that work is priced, approved, photographed, and invoiced.

Should flashing be replaced during roof replacement?

Sometimes yes, sometimes no. The scope should say which flashing will be replaced, reused, repaired, or excluded. Pay close attention to chimneys, sidewalls, skylights, valleys, pipe boots, and roof-to-wall intersections.

Are gutters included in roof replacement?

Not automatically. Some roof scopes include gutter removal and reset, some include gutter replacement, and some exclude gutters entirely. Ask how gutters will be protected and whether gutter cleaning related to roofing debris is included.

What paperwork should I receive after the job?

Ask for the final invoice, warranty instructions, product information, permit or inspection records where applicable, deck repair notes or photos, and a list of any conditions the contractor observed but did not repair.

Can RoofPredict decide whether a roof replacement scope is correct?

No. RoofPredict can help organize photos, property context, notes, reports, and follow-up tasks. A licensed contractor, local building official, manufacturer instructions, and the signed contract control project-specific decisions.
