This article will discuss warranties, price, features, and more. Mr. Happy House is here to provide the facts and give you a review of the GAF Timberline HDZ shingles and why we use them on every roof installation.

What are GAF Timberline HDZ Shingles?

Timberline HDZ shingles are a line of asphalt shingles produced by GAF, a roofing shingle manufacturing company. These shingles are the number one shingles in the nation and they are produced by one of the top manufacturing companies in the United States – GAF. 

These shingles were the first shingles in the country to obtain a wind warranty with no maximum wind speed. They utilize layer-lock technology which is shingle to shingle seal that mechanically fastens the shingles together. This allows the shingles to be more durable against strength and wind uplift. This line of shingles offers almost two inches of nailing zone. 

GAF tested and found this extra-large nailing zone increased installation time by 30% compared to their Timberline HD shingles. It is almost impossible to miss the strike zone on these shingles, unless the installer is not experienced in roofing.

Pros of GAF Timberline HDZ Shingles

There are a lot of pros to using GAF Timberline HDZ shingles. GAF is the top asphalt shingle company in the United States and their shingles come in multiple color options. They also have one of the best warranties and they allow a warranty to be transferred to a second owner if the house is sold during its warranty coverage period. 

Many homeowners prefer the Timberline HDZ shingles because of their layer-lock technology and the larger strike zone. The GAF Timberline HDZ shingles have a stronger bond and lower installation time compared to other shingles. 

This allows roofers like us to get work done accurately and get off a roof in a timely manner. In this part of the article is going to go more in-depth on the pros of using GAF Timberline HDZ shingles.

GAF is North America's Leading Roofing Shingle Manufacturer

GAF is North America’s top manufacturers of asphalt shingles. It is estimated that GAF products cover 1 in 4 houses in the United States! GAF has been in business since 1886 and they have led the roofing industry in several different technological advances. Since GAF has been in business for a long time and has an outstanding reputation and foothold in the roofing industry, it is unlikely they will stop producing shingles anytime soon. 

This means that their products will be available for a long time. Therefore, if a house needs extra shingles for an additional patio cover addition, the homeowner will not have to hunt down a matching color and style. This is not an issue for people who use Mr. Happy House to install their roofs. Mr. Happy House is certified to work with GAF Timberline HDZ shingles and will ensure the shingles are properly installed.

GAF Timberline Shingles Have Multiple Color Options

GAF Timberline HDZ shingles come in a variety of different colors. This allows people to ensure their home’s roof will meet HOA requirements if the neighborhood has an HOA. The Timberline HDZ Shingles even have a collection of colors called the Harvest Blend collection

It is no easy task to pick which color shingle matches a house’s exterior paint color and the style of the house. Our team at Mr. Happy House can help with that decision. We are a local company in The Woodlands, Tomball, Spring, and Northwest Houston area and are familiar with some of the HOA requirements in the area. We can also help determine which roof shingle color will best match your home’s exterior paint color and architectural style.

GAF Offers some of the Best Roof Warranties

GAF has one of the best warranty policies when compared to other brands of shingles. This is great for both the homeowner and the contractor. GAF’s warranties do often require the purchase of accessory products to qualify for the warranty. Our team at Mr. Happy House ensure the proper accessories have been installed on your roof to qualify for GAF’s top warranty. 

The Timberline HDZ shingles are the first line of shingles to have a wind warranty with no maximum wind speed. GAF did this because of how durable the shingles are. The Timberline HDZ shingles also release copper overtime to protect the roof from blue-green algae. This feature is part of their stain guard and algae protection.

Warranty Can Be Transferred if the Home is Sold

Not every homeowner plans to live in a house for their entire life, but the roof may need to be replaced sometime during occupancy. With GAF shingles, the warranty can be transferred to a new homeowner once the house is sold. GAF requires an email or phone call from the new homeowner stating the address and the date the property was purchased. 

They want written notification within 60 days of purchasing the house. They may also ask for the deed or other verification that the property has been purchased. This is an amazing feature as many other roofing shingle manufacturers do not offer this as an option. Being able to transfer the warranty is beneficial for both the current homeowner and a future homeowner.

Layer-Lock Technology

The GAF Timberline HDZ shingles layer-lock technology mechanically fastens and strengthens the common bond on the shingles. This technology along with the increased strike zone allows nails to pass through two layers of shingles. 

Once the shingles are laid down they are secured to the roof by the adhesive bond in at the ends of the shingle. This layer-lock technology provides can provide you ease and comfort because this is what allows these roofing shingles (specifically the Timberline HDZ shingles) to have no maximum wind limit.

Cons of GAF Timberline HDZ Shingles

One issue with roofing warranties is that homeowners often have to jump through hoops to use the warranty and while GAF does have one of the best roofing shingle warranties, it doesn’t mean GAF will pay for the replacement of your roof if it isn’t installed properly, which is why it is highly important to hire a reputable and experienced roofing company to perform the installation. 

However, if there is a problem after installation that is related to the roofing shingles, GAF will require proof of damage. This can be a time-consuming task and often requires a lot of back and forth communication and photos. GAF wants to ensure that the issue is with the product and not with the contractor who installed the roof, which is why it is highly important that you do a lot of research on finding the best roofing contractor who has experience in installing GAF Timberline HDZ shingles.

In Conclusion

GAF is one of the leading shingle companies across the country and the Timberline HDZ shingles are their number one product. GAF has been producing shingles for over a decade and there is no sign they will be backing down production. Therefore, their products will be available years after the roof has been installed. 

There are a lot of pros to using the Timberline HDZ shingles such as the color options, affordability and quality compared to other shingles, and so much more. Once a shingle has been chosen it is important to choose a contractor who is GAF Certified as GAF will not provide a warranty unless the roofer is certified. 

That is where our team at Mr. Happy House can come in. We are professional roofers in The Woodlands, TX. We are certified through GAF and will ensure everything is installed properly so that you can have a long lasting and beautiful roof.
