At first glance, roofs can seem fairly straightforward. In reality, modern roofs are complex and dynamic, and they contain multiple layers and specially designed features to provide excellent longevity and protection. When the time comes to replace your roof, you’ll find that choosing the right components for each element of your roof is essential. Here are some of the basic elements of a roof and a few reasons why GAF components and certified installation is so useful in the Lexington, KY, area.

Structural and Protection

The primary structural layer of your roof is called the roof deck. Your roof deck is typically made of wood, and it provides support for the layers and elements which lie on top of it. Roof decks, however, require protection, and there are several layers to go on before shingles are added.

The underlayment is a protective layer which typically relies on synthetic materials, many of which include fiberglass. It provides an extra layer of protection against water damage. Furthermore, this thin layer can also keep wind-driven elements from damaging your roof deck. The underlayment works in conjunction with the ice and water barrier, which is especially important in areas like Lexington, KY, which receive ample rain and snow. No matter how well a roof is constructed, Mother Nature has a way of forcing water into small cracks. These protection layers work to prevent harm.


Even shingles are more complex than many people realize. One of the most important elements of your shingle system is the starter strip shingles, which are installed along the eaves and roof rake edges. They protect against wind damage, keeping your other shingles in place, and they help form a moisture-proof barrier, extending the lifespan of other roof elements.

Next, your roof replacement will require installing standard shingles. The shingles provide the primary defense against moisture damage, and they also ensure your roof structure remains intact in harsh conditions. Although many materials can be used for shingles, asphalt shingles are by far the most common. Unlike other elements of your roof, shingles are also relatively inexpensive to replace. Using them helps keep other parts of your roof protected for decades.

Ridge shingles are designed to cover multiple shingles which meet at an angle.

Attic and Ventilation

Perhaps the most surprising element of roof design is how complex attics are. Proper ventilation is essential for maintaining the right temperature and humidity in your home, especially in areas such as Lexington, KY, where the temperature varies dramatically over the year.

Ridge attic ventilation is a popular contemporary option, and it provides an efficient way to maintain the ventilation needed in your attic. When you’re installing a new roof, you also have the opportunity to consider any changes you want to make to your attic. If your roof hasn’t been replaced in a long time, you may find it worth investing in an attic redesign to make it easier to control your home’s climate. In some cases, adding a few modern additions can lead to significantly lower energy bills.

Expertise Matters

When planning your roof replacement, it’s important to ensure all elements are designed to work well together. For this reason, many experts recommend only working with a GAF Certified Roofing Expert. These professionals know how to design a roof which makes the most of the elements used, and they can help you avoid potentially costly mistakes less experienced roof designers might make.

Furthermore, working with a certified expert opens up a number of special warranty options. Because your roof is a significant investment, knowing these extended options are available can offer peace of mind, and they let you rest assured your roof can be appropriately serviced if issues arise in the future. Know that you have an important role to play in the roof design process. Start the process early so you can provide the input your roofer needs to help determine the best options.

Installing a new roof can be somewhat nerve-wracking. However, experts are available to help walk you through the process. They will work to design a roof which will protect your home for decades to come. Because of this, it’s always best to work with a local provider whenever possible. By working with AIC Roofing & Construction, you’ll be able to work with a GAF Master Elite Contractor with ample experience using the best components available.
