When investing in a new roof, one crucial aspect that homeowners should carefully consider is the roofing warranty. A warranty provides peace of mind, ensuring that the roof's quality and performance are protected against potential defects or failures. However, understanding the different types of warranties and what they cover is essential to make an informed decision. In this blog post, we will delve into roofing warranties, including manufacturer warranties from reputable companies like IKO and GAF, as well as company warranties provided by roofing contractors. Let's explore what's covered, what's not, and the cost of these warranties to help homeowners make the best choice for their roofing needs.


Manufacturer Warranties:

Manufacturer warranties, also known as material warranties, are offered by the roofing material manufacturers. Companies like IKO and GAF provide various warranty options to back their roofing products, each with different coverage periods and conditions.

a. Limited Lifetime Warranty: This type of warranty is often the most comprehensive and commonly offered by manufacturers. It typically covers the roofing material against defects, premature aging, and granule loss for the lifetime of the original homeowner or a specified period. b. Limited Warranty: The limited warranty provides coverage for a specified number of years but may not last the entire lifetime of the roof. It usually covers manufacturing defects but may not include granule loss or other issues not directly related to manufacturing. c. Prorated Warranty: Some manufacturer warranties may be prorated, meaning the coverage decreases over time. As the roof ages, the manufacturer may cover a decreasing percentage of replacement or repair costs.

Company Warranties:

Apart from manufacturer warranties, roofing contractors may also offer their own company warranties. These warranties are often called workmanship warranties or installation warranties. Unlike manufacturer warranties that cover the roofing material, company warranties protect against installation-related issues.

a. Workmanship Warranty: A workmanship warranty covers the quality of the roofing installation provided by the contractor. It assures the homeowner that the roofing company will fix any installation-related problems during the specified warranty period.


What's Covered in Roofing Warranties:

Manufacturer Warranties:

a. Material Defects: Manufacturer warranties typically cover roofing materials against defects in materials, such as shingle defects or manufacturing flaws. b. Premature Aging: Some manufacturer warranties protect against premature aging, which occurs when the roof fails to perform as expected within a specific time frame. c. Granule Loss: Many warranties cover the loss of granules on asphalt shingles, which can affect their protective properties and overall lifespan. d. Algae Resistance: Some warranties include protection against algae growth on shingles, ensuring the roof's appearance remains attractive.


Company Warranties:

a. Installation Errors: Workmanship warranties ensure that the roofing company will correct any installation errors that lead to leaks, water damage, or other issues. b. Flashing and Sealing: Company warranties often cover problems related to flashing and sealing around roof penetrations, ensuring water-tightness and proper installation. c. Ventilation Issues: Workmanship warranties may address ventilation problems caused by improper installation, which can impact energy efficiency and indoor comfort.


What's Not Covered in Roofing Warranties:

Manufacturer Warranties:

a. Acts of Nature: Manufacturer warranties typically exclude coverage for damage caused by natural disasters or extreme weather events, such as hurricanes, tornadoes, or hailstorms. b. Improper Installation: If the roofing material is not installed according to the manufacturer's guidelines or industry standards, the warranty may be voided.


Company Warranties:

a. Manufacturer Defects: Company warranties do not cover material defects, as these issues fall under the manufacturer's responsibility. b. Acts of Nature: Like manufacturer warranties, company warranties usually exclude damage caused by natural disasters or extreme weather events.


Cost of Roofing Warranties:

The cost of roofing warranties can vary depending on several factors, including the type of warranty, the roofing material used, and the roofing company's reputation. Manufacturer warranties are often included in the price of the roofing material, while company warranties are typically an additional expense.

Manufacturer warranties may be prorated, meaning the coverage decreases over time, and premium warranties with longer coverage periods may come at a higher cost. It's essential for homeowners to understand the terms and limitations of the warranties and weigh the cost against the added protection and peace of mind.

IKO and GAF Warranties: IKO and GAF are two well-known roofing material manufacturers, and both offer comprehensive warranties to back their products.

IKO: IKO provides a range of warranty options, including their Limited Lifetime Warranty and Iron Clad Protection Warranty. Their warranty coverage varies based on the specific roofing material used and its quality level.

GAF: GAF's warranties include the GAF Shingle & Accessory Limited Warranty, providing coverage for their asphalt shingles and associated accessories. They also offer the GAF Systems Plus Limited Warranty, offering additional protection when installing multiple GAF products together.

Understanding roofing warranties is vital when considering a new roof installation. Manufacturer warranties provide coverage for material defects, premature aging, granule loss, and algae resistance. On the other hand, company warranties protect against installation errors and workmanship issues. When evaluating warranties, it's crucial to know what's covered and what's not, as well as any exclusions or limitations.

Homeowners should thoroughly review the terms and conditions of both manufacturer and company warranties before making a decision. Consider factors such as the warranty coverage period, prorating, transferability, and any required maintenance to maintain the warranty's validity.

Tips for Maximizing Roofing Warranties:

  1. Choose Quality Materials: Opt for roofing materials from reputable manufacturers like IKO and GAF, known for their reliable warranties and durable products.

  2. Hire Professional Roofers: Select a licensed and experienced roofing contractor to ensure proper installation and adherence to manufacturer guidelines, avoiding potential warranty voids due to installation errors.

  3. Perform Regular Maintenance: Regular roof maintenance, such as clearing debris, inspecting for damage, and addressing minor issues promptly, can help prolong the life of the roof and maintain warranty coverage.

  4. Document Roof Repairs: Keep records of any repairs or maintenance performed on the roof, as some warranties may require proof of proper maintenance to remain valid.

  5. Read the Fine Print: Thoroughly read and understand the warranty terms, including any exclusions or limitations, to know precisely what is covered and what actions could void the warranty.

  6. Work with Certified Installers: For certain manufacturer warranties, using certified installers may provide additional benefits or extended coverage.

  7. Review Workmanship Warranties: When choosing a roofing contractor, inquire about their workmanship warranty and the duration of coverage they offer for their installation services.

Roofing warranties play a critical role in protecting homeowners from unexpected expenses related to roofing defects and installation errors. Manufacturer warranties from reputable companies like IKO and GAF cover material defects, premature aging, granule loss, and algae resistance. Meanwhile, company warranties safeguard against installation errors and workmanship issues. Homeowners must carefully read and understand the warranty terms and take proactive steps to maintain their warranty's validity. By choosing quality materials, working with professional roofers, and performing regular maintenance, homeowners can ensure that their roof remains protected and covered for years to come.
