Roof Replacement

Know why
before you replace.

A roof replacement is a major investment. Whether your roof is showing its age, experiencing repeated problems or has already been recommended for replacement, you should understand the evidence supporting that recommendation—and the complete system you are purchasing.

Dominion evaluates the condition of the roof, explains why replacement may or may not be appropriate and provides a written scope that defines what will be installed beyond the shingles you see.

01Does Your Roof Really Need Replacement?

Does your roof really need to be replaced?

Finding a problem with a roof is not the same as proving that the entire roof needs replacement.

A leak, damaged shingle, deteriorated pipe boot or installation deficiency may be a legitimate concern, but the existence of one problem does not automatically determine the solution. Some conditions can be corrected with a targeted repair. Others may be symptoms of deterioration or deficiencies affecting a much larger portion of the roofing system.

Age matters, but age alone is not a diagnosis either. An older roof may remain serviceable or repairable, while a newer roof may have significant problems caused by materials, installation, ventilation or storm-related conditions.

A credible replacement recommendation should explain:

  • What conditions were observed
  • Where those conditions are located
  • How much of the roofing system is affected
  • Whether the problems are isolated or widespread
  • Whether a reliable repair is possible
  • What limitations or unknowns remain
  • Why replacement is more appropriate than repair or continued monitoring
  • What evidence supports the recommendation

A roof replacement should not be recommended simply because one problem was found or because the roof has reached a particular age. The recommendation should be supported by the condition of the complete roofing system and a clear explanation of why replacement is the appropriate next step.

02More Than Shingles

You are not just buying shingles. You are buying a roofing system.

Shingles are the most visible part of a roof, but they cannot perform properly by themselves. A complete roof replacement must account for the materials and details that support the roof, manage water, seal vulnerable areas and provide balanced ventilation.

Depending on the home and approved scope, the roofing system may include:

  • Roof decking
  • Drip edge
  • Ice-and-water protection
  • Underlayment
  • Starter shingles
  • Field shingles
  • Step, wall and chimney flashing
  • Pipe boots and other penetrations
  • Intake ventilation
  • Exhaust ventilation
  • Fasteners
  • Ridge-cap shingles

A roofing proposal should clearly explain how each applicable component will be handled. It should identify what will be removed, replaced, reused, added, inspected or excluded.

Two contractors may propose the same shingle brand while providing very different roofing systems. The quality and completeness of the scope matter just as much as the product name printed on the bundle.

03What Tear-Off Can Reveal

Some conditions cannot be confirmed until the roof is removed.

A complete roof evaluation should consider more than what can be seen from the exterior. That is why Dominion makes attic access a priority whenever the space can be entered safely.

The exterior inspection shows the condition of the roof covering, flashings, penetrations and other visible components. The attic provides another perspective by allowing the inspector to evaluate the accessible underside of the roof deck for staining, deterioration, previous water entry and other visible concerns.

Looking at the roof from both sides can reveal conditions that may be missed during an exterior-only inspection. It can also help determine whether an isolated exterior concern has affected the decking beneath it.

Even with attic access, however, large portions of the deck may remain concealed or inaccessible. Tear-off provides the first opportunity to inspect the entire exposed upper surface of the roof deck.

If soft, delaminated, rotted or structurally unsound sheathing is discovered, new roofing materials should not be installed over it. Dominion photographs the affected areas, explains what was found and documents the necessary correction before the decking is covered by the new roofing system.

04The Roof-Replacement Process

A defined process. A documented installation.

01

Confirm the scope

Before work begins, the proposal should identify the roofing materials, applicable components, installation details, known exclusions and how concealed conditions will be handled.

02

Protect the property

The work area is prepared to help protect the home, landscaping and surrounding property during removal and installation.

03

Remove the existing roof

Existing roofing materials are removed so the underlying deck and critical transition areas can be evaluated.

04

Inspect and prepare the decking

The exposed deck is inspected. Deteriorated or structurally unsound areas are documented and corrected before the new roofing system is installed.

05

Install the complete roofing system

Dominion replaces the underlayment, protective membrane, starter, flashings, ventilation, hip and ridge cap, and shingles according to the approved scope and applicable installation requirements.

06

Complete the work and document the result

The work area is cleaned, the completed roof is reviewed and the finished installation is documented.

05Comparing Roofing Proposals

The same shingle does not always mean the same roof.

Two proposals may name the same shingle manufacturer and color while including very different materials, installation details and contractor responsibilities.

Before comparing the totals, compare how each proposal addresses:

  • Removal and disposal of the existing roofing materials
  • Decking inspection, allowances and pricing for necessary replacement
  • Drip edge and edge-metal details
  • Ice-and-water protection
  • Underlayment
  • Starter shingles
  • Field shingles
  • Step, wall and chimney flashing
  • Valleys and roof transitions
  • Pipe boots and other penetrations
  • Intake and exhaust ventilation
  • Fastener type, placement and installation requirements
  • Ridge-cap shingles
  • Property protection and cleanup
  • Permits and inspections, when required
  • Manufacturer and workmanship warranties
  • Exclusions, allowances and change-order procedures

A lower proposal may represent a genuine price difference, a different roofing system or work that has been omitted or left undefined. The proposal should make those differences clear enough for the homeowner to compare the complete scope—not merely the shingle brand and final number.

06What Affects Roof-Replacement Cost?

Why can roof-replacement prices vary?

Roof-replacement cost depends on more than the home’s interior square footage or the price of the selected shingle.

Important factors can include:

  • The measured roof area
  • Roof pitch, height and accessibility
  • The number of slopes, valleys, dormers and transitions
  • The number of existing roofing layers
  • Tear-off and disposal requirements
  • Material type and roofing-system components
  • Flashing, ventilation and penetration details
  • The amount of damaged decking discovered
  • Property-protection requirements
  • Permit and inspection requirements
  • Warranty level and eligibility requirements
  • Other project-specific conditions included in the written scope

A responsible proposal should explain what is included in the price, what remains an allowance and which conditions could change the final scope. Without that information, two totals cannot be compared accurately.

07Choosing the Right Roofing System

The right roof is not the same for every home.

Material selection should account for more than color, brand recognition or the longest warranty printed in a brochure.

The appropriate roofing system depends on factors such as:

  • The home’s architecture and roof configuration
  • Expected service life
  • Installation requirements
  • Maintenance expectations
  • Appearance
  • Budget
  • Ventilation and water-management needs
  • Manufacturer requirements
  • Warranty eligibility
  • The homeowner’s long-term plans for the property

Architectural asphalt shingles may provide an appropriate balance of performance, appearance and cost for many homes. Standing-seam metal may be considered when the homeowner values a different appearance, system design and long-term ownership strategy.

The material is only one part of the decision. Even a high-quality product depends on the decking, underlayment, flashing, ventilation, fasteners and installation details beneath and around it.

08Understanding Roofing Warranties

A material warranty and a workmanship warranty are not the same.

Roofing warranties can sound similar while protecting against very different problems.

Manufacturer or material warranties generally apply to qualifying defects in the roofing products. Coverage, duration, proration, registration requirements, transferability, exclusions and available enhanced protection depend on the specific manufacturer and warranty level.

Workmanship warranties address installation-related responsibilities defined by the roofing contractor. Their duration, coverage, exclusions and claims process should be stated clearly in the agreement.

Before selecting a proposal, homeowners should understand:

  • Who provides each warranty
  • What materials and work are covered
  • How long each type of coverage lasts
  • Whether coverage becomes prorated
  • Whether labor, tear-off and disposal are included
  • What registration or contractor qualifications are required
  • Whether the warranty can be transferred
  • What maintenance or notification requirements apply
  • Which conditions and causes are excluded
  • Who should be contacted if a problem develops

A long warranty term does not explain everything by itself. The actual coverage, eligibility requirements and responsible party matter.

09Timing and Preparation

How long does a roof replacement take?

The installation timeline depends on the size and complexity of the roof, the materials being installed, weather conditions, accessibility and any concealed conditions discovered during tear-off.

Before work begins, Dominion explains the anticipated schedule and any property preparations that may be needed. Homeowners may be asked to:

  • Move vehicles away from the work area
  • Secure fragile items on walls or shelves
  • Protect belongings stored in the attic
  • Move outdoor furniture and decorations
  • Keep children and pets away from active work areas
  • Make sure gates and necessary access points are available
  • Tell Dominion about any special property concerns before installation begins

Roof replacement involves noise, vibration, falling debris and active work around the home. Clear preparation and communication help protect the property and allow the installation team to work safely.

If weather, damaged decking or another unexpected condition affects the anticipated schedule, Dominion will explain what changed and how it affects the project.

10Roof-replacement questions

Roof-Replacement Questions

What happens if damaged decking is discovered during tear-off?

If damaged or deteriorated decking is discovered during roof tear-off, the affected areas should be documented and replaced before the new roofing system is installed. New roofing materials should not be installed over soft, delaminated, rotted or structurally unsound sheathing.

Because portions of the roof deck may be concealed during the initial assessment, some conditions cannot be confirmed until the existing roofing materials are removed. Dominion photographs the affected areas, explains what was found and documents the necessary correction before the decking is covered by the new roof system.

What should I compare besides price when reviewing roofing proposals?

The lowest roofing proposal is not always the least expensive choice once differences in scope, materials and installation standards are considered. Homeowners should compare exactly what each contractor will install, how vulnerable areas will be handled and what is excluded or left undefined.

Look beyond the shingle brand. Compare underlayment, ice-and-water protection, starter shingles, flashing, ventilation, pipe boots, fasteners, ridge components and provisions for damaged decking. Also review workmanship standards, warranties, contractor qualifications, cleanup, property protection, supervision and how unexpected conditions will be documented and priced.

A thorough proposal should make the complete roofing system understandable. If two prices are significantly different, the first question should be what is missing or different—not simply which number is lower.

11Roof Replacement

Replace your roof with a clear understanding of why.

If your roof truly needs replacement, Dominion will show you the evidence supporting that recommendation and clearly define the roofing system you are purchasing.

If repair, monitoring or further evaluation is more appropriate, the assessment should make that clear too.
