Our goal is not simply to put new shingles on your house. We build a complete roofing system designed to protect your home for years to come.

When Should You Replace Your Roof?

Not every roofing problem requires a complete replacement. Some issues can be resolved with professional roof repair. However, replacement may make more sense when the roof has widespread or recurring problems.

Common signs that you may need a new roof include:

  • Your roof is approaching or exceeding its expected lifespan
  • Shingles are cracked, curling, loose, or missing
  • Granules are washing into gutters
  • Leaks continue after previous repairs
  • The roof has widespread storm or hail damage
  • There are visible areas of sagging
  • Flashing or other roofing components are deteriorating
  • Your roof requires frequent repairs
  • Water damage is affecting the roof deck or interior
  • The roofing system has significant age-related deterioration

Can a Roof Be Repaired Instead of Replaced?

Sometimes, yes. A localized leak or isolated shingle problem may only require a repair. However, when damage is widespread or the roofing system is near the end of its useful life, continuing to repair individual problems may not be the most cost-effective long-term solution.

Our team can inspect your roof and explain whether roof repair or complete roof replacement is appropriate for your home.

What's Included in Our Roof Replacement Service?

A professional roof replacement involves much more than installing new shingles.

  1. 1

    Roof Inspection & Assessment

    We begin by evaluating the existing roofing system and identifying visible damage, deterioration, ventilation concerns, flashing problems, and other conditions that may affect the replacement.

  2. 2

    Full Roof Tear-Off

    When a complete replacement is required, the existing roofing materials are removed so the underlying roof deck can be properly inspected.

  3. 3

    Roof Deck Inspection

    After the old roofing material is removed, we inspect the deck for signs of deterioration or damage. Any necessary preparation should be addressed before the new roofing system is installed.

  4. 4

    Underlayment & Ice-and-Water Protection

    We install the appropriate protective layers as part of the roofing system, including upgraded underlayment and ice-and-water protection where required or appropriate.

  5. 5

    Flashing & Roof Details

    Roof-to-wall areas, valleys, penetrations, chimneys, and other vulnerable areas require proper flashing and detailing to help prevent water intrusion.

  6. 6

    GAF Architectural Shingles

    We install GAF Timberline HDZ® architectural shingles, a popular roofing option designed to provide durable protection and an attractive finished appearance.

  7. 7

    Ventilation

    Proper attic ventilation is an important part of a roofing system. We evaluate ventilation as part of the replacement process and address applicable ventilation requirements.

  8. 8

    Final Inspection & Cleanup

    After installation, we inspect the completed roofing system and clean the work area so your property is left in good condition.

How Much Does a New Roof Cost in New Jersey?

The cost of a new roof depends on several factors, so there is no single price that applies to every New Jersey home.

The roof replacement cost can be influenced by:

  • Roof size and complexity
  • Number of roofing squares
  • Roof pitch
  • Existing roofing layers
  • Condition of the roof deck
  • Shingle type and roofing materials
  • Flashing requirements
  • Ventilation requirements
  • Skylights, chimneys, and other roof penetrations
  • Accessibility of the property
  • Required repairs or structural preparation
  • Local project requirements

How Much Does It Cost to Replace a Roof?

A professional estimate is the best way to determine the actual cost of replacing your roof. Online averages can provide general context, but they cannot account for the condition, size, design, and material requirements of an individual New Jersey home.

Instead of relying on a generic roof replacement price, Alte Roofing & Siding can inspect your roof and provide a project-specific estimate.

How Long Does a Roof Replacement Take?

The time required to replace a roof depends on the size and complexity of the project, weather conditions, material availability, roof condition, and any additional work discovered during the replacement.

A straightforward residential roof replacement may be completed relatively quickly, while larger or more complex roofs can require additional time.

Before work begins, our team can explain the expected project timeline based on your home's specific roofing system.

Should I Stay Home During Roof Replacement?

You generally do not need to remain inside your home throughout the entire roofing project. However, roof replacement can create considerable noise and activity around the property.

If you work from home, have young children, pets, or have other concerns about noise and access, discuss them with your roofing contractor before installation begins.

How Long Does a Roof Last?

The lifespan of a roof depends on the roofing material, installation quality, weather exposure, ventilation, maintenance, and other factors.

For homeowners asking how long a roof lasts, there is no universal number that applies to every roofing system. A roof exposed to severe weather or poor ventilation may deteriorate differently from one that is properly installed and maintained.

Regular inspections can help identify aging or damaged components before they develop into larger problems.

How Often Should a Roof Be Replaced?

There is no fixed replacement schedule for every home. A roof should be evaluated based on its age, condition, material, installation, and history of repairs.

If your roof is aging and you are experiencing recurring leaks, missing shingles, widespread deterioration, or other problems, a professional inspection can help determine whether repair or replacement is appropriate.

Our GAF Roofing System

For qualifying projects, we install GAF Timberline HDZ® architectural shingles as part of a complete roofing system.

A roofing system is made up of multiple components working together — not just the visible shingles.

Depending on the project, the system may include:

  • Architectural shingles
  • Underlayment
  • Ice-and-water protection
  • Starter strips
  • Ridge cap shingles
  • Flashing
  • Ventilation components
  • Roof deck preparation

We also offer access to applicable GAF warranty options for qualifying installations.

Roof Replacement vs. Roof Repair

Choosing between repair and replacement depends on the condition of your existing roof.

Roof RepairRoof Replacement
Localized damageWidespread deterioration
Isolated leaksRecurring or multiple leaks
Small number of damaged shinglesLarge areas of damaged shingles
Roof has significant remaining service lifeRoof is near the end of its useful life
Limited damageExtensive storm or age-related damage

A professional inspection is the best way to determine which option makes sense for your property.

Frequently Asked Questions

How much does a roof replacement cost?

Roof replacement cost varies based on roof size, design, materials, pitch, existing roof condition, deck repairs, flashing, ventilation, and other project requirements. The most accurate way to determine your cost is through a professional roof inspection and estimate.

How long does it take to replace a roof?

The installation timeline depends on the size and complexity of the roof, weather, materials, and any additional preparation required. Your project estimate can provide a more specific expected timeline.

How long should a roof last?

Roof lifespan varies according to roofing material, installation quality, weather exposure, maintenance, ventilation, and other conditions. An inspection can help determine the current condition of an aging roof.

When does a roof need to be replaced?

A roof may need replacement when it has widespread damage, recurring leaks, extensive shingle deterioration, significant age, or other conditions that make continued repairs impractical.

Should I repair or replace my roof?

A localized roofing problem may be repairable, while widespread deterioration or an aging roofing system may justify replacement. A professional inspection can help determine which option is appropriate.

Does homeowners insurance cover roof replacement?

Homeowners insurance coverage depends on the policy and the cause of the damage. Sudden covered events such as certain types of storm damage may be treated differently from normal aging, deterioration, or lack of maintenance. Review your policy and speak with your insurance provider about your specific coverage.

Can hail damage require a roof replacement?

Yes. Significant hail damage can affect shingles and other roofing components. The appropriate solution depends on the severity and extent of the damage. A professional inspection can determine whether repairs or replacement are warranted.

How often should you replace your roof?

There is no universal replacement interval. Roof age, material, installation quality, weather exposure, maintenance, ventilation, and damage history all affect how long a roof remains serviceable.

What is included in a roof replacement?

A complete replacement may include removal of existing roofing, roof deck inspection, underlayment, ice-and-water protection, flashing, ventilation components, new shingles, ridge caps, and cleanup, depending on the project.

How many roofing squares are needed for my home?

A roofing square represents 100 square feet of roofing area. The number required depends on the actual roof surface area and additional material needed for installation. A professional measurement provides the most accurate calculation.
