What's GAF Timberline HDZ Shingles Warranty?

By

When it comes to selecting roofing materials, understanding the warranty is crucial to ensure you're making a sound investment. GAF Timberline HDZ shingles, a top choice among homeowners and contractors alike, come with a comprehensive warranty program. But what does this mean for you? Let's delve into the details of the warranty on GAF Timberline HDZ shingles.

Firstly, it's essential to understand that GAF offers not one, but two warranties for their Timberline HDZ shingles: a lifetime limited warranty and a wind warranty. Both warranties are designed to provide homeowners with peace of mind, knowing that their roof is protected against various potential defects and damages.

The Lifetime Limited Warranty

The lifetime limited warranty covers any manufacturing defects in the Timberline HDZ shingles for as long as the original homeowner owns their home. This warranty is transferable once to the next homeowner, adding to the appeal of GAF products for home sellers.

However, it's crucial to note that this warranty does not cover general wear and tear,Impact damage, or damage caused by improper installation. To maintain the warranty's validity, it's imperative to install the shingles according to GAF's specifications and have the work done by a GAF-certified roofing contractor.

Lifetime Warranty Coverage

The lifetime limited warranty covers 100% of the cost of replacement (prorated for the length of ownership) for shingles found to be defective due to manufacturing issues. This includes labor costs, up to the amount initially paid for labor when the roof was installed.

Moreover, GAF offers non-prorated coverage for the first 10 years, meaning there are no deductions from the replacement cost during this period. After the initial 10 years, coverage is prorated based on the shingle's age.

30-Year Warranty on Starts

In addition to the lifetime coverage on the shingles, GAF also offers a 30-year warranty on the starter strip shingles used at the eaves and rakes of the roof. These shingles are designed to protect against wind uplift and provide a weather-tight seal at the edges of the roof.

The 30-year warranty covers 100% of the cost of replacing the starter strip shingles if they are found to be defective due to manufacturing issues. This warranty also covers labor costs, up to the amount initially paid for labor during the roof's installation.

The Wind Warranty

GAF Timberline HDZ shingles are designed to withstand high winds, making them an excellent choice for homeowners in areas prone to severe weather. The wind warranty provides additional coverage against wind damage, above and beyond the lifetime limited warranty.

This warranty covers repair or replacement costs if the shingles are damaged or blown off due to wind speeds up to 130 mph (depending on the specific product you choose). The coverage period and the amount covered vary by product, so it's essential to consult the warranty documents for specific details.

Coverage Period and Amount

The wind warranty coverage period typically ranges from 15 to lifetime, depending on the specific GAF Timberline HDZ product you choose. For instance, Timberline HDZ series with Dura Grip adhesive seals come with a lifetime wind warranty, while other series may have a 15-year wind warranty.
