Best Roof Replacement Methods

When it comes to replacing your roof, choosing among the best roof replacement methods is critical. Roof replacement is a significant investment, and the method you select can impact the cost, lifespan, and overall performance of your new roof. The professionals with Dickson Roofing have information on different methods, including when and why to choose them.

Tear-Off and Re-Roof

Best Roof Replacement MethodsThe tear-off and re-roof method is one of the most common approaches to roof replacement. It involves removing the existing roofing materials, such as shingles, and replacing them with new ones. This method is often chosen when the underlying structure of the roof is in good condition and there’s only a need to replace the exterior layer.


  • Ensures a fresh start with new roofing materials.
  • Allows for a thorough inspection of the roof deck and structure.
  • Suitable for various roofing materials, including asphalt shingles and metal roofing.


  • May be more labor-intensive and time-consuming.
  • Can generate more waste due to the removal of the old roofing materials.


A roof-over, also known as a layover, involves placing new roofing materials over the existing ones. This method is a cost-effective and time-saving alternative to a tear-off and re-roof. It’s generally suitable when the old roofing materials are in relatively good condition and you want to add an additional layer of protection.


  • Reduces labor and disposal costs.
  • Provides an extra layer of insulation and protection.
  • Faster installation compared to a tear-off.


  • May not be suitable for all types of roofs or in areas with building code restrictions.
  • The added weight of multiple layers can strain the roof’s structure.

Metal Roof Retrofit

If you have an existing shingle roof and want to upgrade to a more durable and long-lasting material, a metal roof retrofit is a viable option. This method involves installing a metal roof over the existing shingles, creating a protective barrier.


  • Metal roofs are exceptionally durable and have a long lifespan.
  • Enhanced energy efficiency and curb appeal.
  • Minimal disruption to the interior of your home during installation.


  • The roof deck and structure must be in good condition to support the added weight.
  • There may be more budget-friendly options, but it offers long-term savings.

Full Roof Restoration

Roof restoration is a method that focuses on extending the life of your existing roof by repairing, re-coating, and reinforcing it. It’s especially suitable for flat or low-slope roofs and can be a cost-effective alternative to complete replacement.


  • Extends the life of your existing roof.
  • Restores the waterproofing capabilities of your roof.
  • Cost-effective compared to full replacement.


  • Not suitable for roofs with extensive structural damage.
  • Requires periodic maintenance and re-coating to maintain effectiveness.
