Our Warranty Breakdown:

Material warranties are through the manufacturer and can range from 25 years to Lifetime, which is 50 Years depending on the manufacturer and the materials being installed for your project.

Workmanship warranties or also known as labor warranties vary depending on the product being installed. Here’s a brief explanation of our workmanship warranties:

Roofing: 5 Years to 25 Years; depending on the materials being installed. 25 Year Workmanship warranties may also be backed by a manufacturer if you purchase the warranty upgrade.

Siding: 10-Year Workmanship Warranty

Windows & Doors: 10-Year Workmanship Warranty

Gutters & Gutter Guards: 1-Year Workmanship Warranty

Repair Services: 1-Year Workmanship Warranty

Note: Warranties are subject to change and will always be listed on any written proposal or signed contract. Your signed contract is considered proof of warranty with St Joseph’s Roofing. So, please make sure you retain your signed contract for your records.

What is the difference between your workmanship warranty and a material warranty?

  • Our workmanship warranty protects you in the event that you had a leak caused by improper installation. Example: we install your roof and 3 years later your roof leaks near your chimney. We would be responsible for fixing the leak free of charge.
  • Materials warranties are through the manufacturer of the materials and protect you in the event that the materials fail prematurely. Example: we install your siding and 12 years later it is warped and discolored. The manufacturer would be responsible for providing new materials (usually at a prorated rate.)

NOTE: The most common problems are usually NOT caused by the materials, in most cases where people have problems with their roofing, siding, or gutters it is caused by something the installer did wrong. That is why the company you choose to install your new roofing, siding, gutters or windows can make the difference between major headaches and peace of mind.

Understanding the Basics of Roofing Warranties

Although it may seem as though there’s a wide range of warranties offered on roofing, there are really just three main types:

  • The standard manufacturer’s warranty that covers the products you purchase
  • workmanship warranty from your contractor that covers the installation
  • An extended manufacturer’s warranty that covers contractor workmanship along with expanded coverage for the products

Here, we’ll take a closer look at the coverage provided by each type and explain what it means in practical terms.

Standard Manufacturers’ Warranties

Most roofing shingles come with a basic limited lifetime warranty, which is the industry standard. In most cases, a lifetime warranty means you’re covered as long as you own your home. The degree of protection you receive depends on the definition of “limited,” and this can vary depending on the manufacturer:

  • Most manufacturer warranties strictly cover the cost of defective materials, so you’re responsible for any labor charges to remove and dispose of failed shingles and install the replacements.
  • Most manufacturers cover the cost of replacing defective shingles for the first few years and then offer prorated coverage from that point on. If any shingles are found to be defective during the initial period, the manufacturer gives you replacement shingles at no cost. This initial coverage also includes labor costs for installation of the replacement shingles but doesn’t cover tear-off and disposal of the defective shingles. If a failure happens during the prorated period, you’ll receive just a portion of the cost or a lesser amount of new shingles.
  • Industry-wide, these standard manufacturer warranties only provide coverage against factory defects: they don’t cover shingles that prematurely fail because mistakes were made during installation, or issues with any other components your roofer installed, such as ice and water shield, underlayment, flashing or ventilation products. Depending on the manufacturer of these other components, they may be covered by individual warranties against defects, as well.

Contractor Workmanship Warranties

The contractor who installs your roofing plays a key role in its performance and longevity. Reputable, skilled roofers stand behind each installation job with a workmanship warranty. The length of this type of warranty can vary a lot depending on the contractor, but some offer lifetime coverage. While a longer coverage period is better, a good workmanship warranty should protect you against material failures that occur because of worker errors or improper installation techniques regardless of the coverage term.

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

Contractor warranties typically exclude issues that aren’t related to their installation workmanship, such as:

Factors such as a contractor’s length of time in business, their track record of doing quality work, and commitment to customer satisfaction should trump any warranty they claim to offer, so be sure to vet anyone you’re considering hiring thoroughly.

Extended Manufacturer Warranties = Comprehensive Coverage

Leading manufacturers understand the direct connection between installation quality and how well their roofing products perform long-term. To help homeowners get lasting value and provide peace of mind, they offer optional extended warranty coverage on new roofs installed by authorized contractors who are certified to install the roofing system according to the manufacturer’s installation requirements.

Most extended warranties are available for an additional cost and require that you have a complete roof system installed, which usually includes certain coordinating components such as:

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

The most comprehensive extended warranties offered by trusted manufacturers provide a range of benefits, such as:

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

Don’t Neglect Warranty Registration

Once you’ve chosen a brand of roofing and an installation contractor and decided that an extended warranty is your best option, be sure to check the manufacturer’s requirements for registering your warranty.

If an authorized contractor is handling the installation of your new roof, they may have to register its warranty with the manufacturer within a specified time frame.

Double-checking that the requirements have been met can help you avoid any headaches about non-registration if you have to file a warranty claim in the future.

Not much can protect you against installation defects apart from a roof workmanship warranty from the installer.

Also keep in mind that a warranty is only as good as the company backing it. 

NOTE: The most common problems are usually NOT caused by the materials, in most cases where people have problems with their roofing, siding, or gutters it is caused by something the installer did wrong. That is why the company you choose to install your new roofing, siding, gutters or windows can make the difference between major headaches and peace of mind.
