Types of Roofing Warranties

There are a wide range of warranties available for you; however, you can divide them into three main types:

  • Standard manufacturer’s warranty: This type of warranty covers the products you purchase
  • Workmanship warranty: This is provided by your contractor and it covers the installation.
  • Extended manufacturer’s warranty: This type of warranty covers contractor workmanship along with expanded coverage for the products.

Let us discuss the coverage provided by each type.


Most roofing shingles come with a basic warranty that has limited lifetime coverage as per the industry standard. 

In most cases, a lifetime warranty provides you coverage as long as you own your home. The coverage you receive varies depending on the manufacturer:

  • Most manufacturer warranties only cover the cost of defective materials. In this case, you are responsible for any labor charges for removing and disposing of failed shingles and installing replacements.
  • Most manufacturers also cover the cost of replacing defective shingles for a certain period. If any shingles are found to be defective during the initial period, the manufacturer is completely responsible for the replacement of shingles. 

This initial coverage also includes labor costs for the installation of the replacement shingles. However, it doesn’t cover the tear-off and disposal of the defective shingles. 

In case of a failure during the prorated period, you only receive a portion of the cost or a lesser amount of new shingles.

  • These standard manufacturer warranties only provide coverage against manufacturing defects. They don’t cover shingles that get damaged due to poor installation techniques. 

It also does not cover the losses that occur due to poor handling during installation such as ice and water shield, underlayment, flashing, or ventilation products. 

However, they may be covered by individual warranties against defects depending on the manufacturer of these products. 


Your roofing contractor is responsible for the longevity of your roof up to a great extent. 

A reputable roofing contractor provides a workmanship warranty that covers the damage that occurs during the installation process. 

The length of this type of warranty might vary depending on the contractor. Some contractors offer lifetime coverage. 

A good workmanship warranty should protect you against failures in materials that occur due to poor handling by a worker or improper installation techniques regardless of the coverage term.

Contractor workmanship warranties cover the cost of labor and the materials needed to make necessary repairs. They also cover any related damages done to the home’s interior, as well as your furnishings and personal effects.

Contractor warranties do not cover the following things:

  • Damage caused by storm, high wind, and impact
  • Water damage due to ice dams
  • Damages caused if your roof is altered after installation
  • The harm caused by foot traffic
  • Leaks happen due to falling tree branches and debris.


A reputable manufacturer ensures high quality of installation and the optimum performance of their roofing products.

The certified roofers offer optional extended warranty coverage on new roof installation. 

However, you might have to pay an additional cost for most extended warranties. This type of warranty covers the following:

  • Ice and water barriers
  • Underlayment
  • Hip and ridge cap shingles
  • Soffit and ridge vents
  • Starter and field shingles

Trusted manufacturers provide a wide range of benefits through an extended warranty:

  • Coverage for all roof system components; excluding flashing, wood decking, and fasteners
  • Lengthy, non-prorated, or continuous, coverage for defective materials. This includes labor costs for repairs or replacements and is extendable for up to 50 years.
  • Workmanship coverage against installation errors of the roof system. This might provide lifetime coverage with prorating beginning after a certain number of years and includes labor, tear-off, and disposal costs.


You should choose an extended manufacturer’s warranty after choosing a brand of roofing and a reputed roofing contractor in your location. This type of warranty will help you with a wide range of benefits. You should check the authenticity of your contractor and check the type of coverage they provide you before hiring them.
