Overview Of GAF Roofing Products

A strong roof relies on the whole system working together, not just the individual components. Underlayment, ventilation, and leak protection all add to its durability and comfort. When these parts work together, your roof performs better year-round and withstands daily wear.

GAF roofing products cover a wide range of roof types, from homes to commercial buildings. You can select materials suited for low-slope areas, steep-slope surfaces, or roofs with multiple sections. When installed correctly, many GAF roofing products also improve energy efficiency and offer reliable warranty coverage.

In Ann Arbor and East Detroit, we help you narrow choices based on roof shape and goals. We also confirm compatibility across layers. That way, your GAF roofing materials work as a single, integrated system.

GAF Residential Roofing Materials

Shingles

Since shingles sit on top of most sloped residential roofs, they’re the layer you notice first. They protect against water and sunlight while also influencing the roof’s appearance. GAF offers many styles and colors, so you can match the roof to your home’s look. It’s a practical way to pair performance with design.

Leak Barriers

Leak barriers reinforce the roof’s most exposed areas, including valleys, edges, and spots around penetrations. Roofers install them at these transition points to help reduce the risk of intrusion. Once shingles go on top, the leak barrier becomes the secondary line of defense. It helps block moisture that gets forced into tight areas during harsh weather.

Roof Underlayment

A roof system works better when the layers support each other, and underlayment is one of those layers. It goes between the deck and the shingles and helps manage moisture. Because it evens out the surface, roofers can install shingles more consistently. When the layout is done correctly, underlayment also strengthens protection at overlaps and fasteners.

Hip And Ridge Cap Shingles

Along the roof’s ridges and hips, cap shingles create a clean finished edge. They cover the seams where roof planes meet, which helps protect those joints. Because they sit right at the peaks and angles, they also improve the roof’s overall appearance. This detail helps the roof look more uniform from the ground.

Ventilation And Roof Vents

Balanced ventilation helps the attic breathe. Moving heat and moisture out through roof vents helps improve indoor comfort, and shingles perform better. Proper airflow also reduces the risk of moisture buildup in the attic. That matters because moisture can degrade insulation and decking over time.

Solar Shingles

Solar shingles are a good choice if you want to generate power without large panels. They lie flat and blend in with your roof, so they look smooth and neat. They work as both roofing and an energy source, making them a great option if appearance is important to you.

Metal Roofing

Roofers often recommend metal because it performs well in changing weather and sheds water reliably. It’s also built for long-term durability, which adds to its value over time. On top of that, metal roofing can suit many residential roof styles and create a more modern finish.

GAF Commercial Roofing Materials

TPO Roofing Membranes

TPO membranes are a good fit for low-slope commercial roofs because they cover large areas without seams. This helps keep out moisture and protects the roof. Many building owners also like TPO because it reflects sunlight, helping keep the building cooler.

PVC Roofing Membranes

Low-slope roofing systems often use PVC membranes as an alternative to other single-ply options. When crews weld the seams correctly, PVC delivers strong seam performance. It also offers chemical resistance, which can be important for roofs exposed to certain exhaust discharges. That added protection supports better long-term system reliability.

Asphaltic Membranes

Asphaltic membranes help create durable commercial roof assemblies, especially in multi-ply systems. They provide a reliable waterproofing layer across low-slope surfaces. Roofers can choose from several installation methods based on the roof design and site conditions, helping tailor the system to the building.

Insulation

Insulation helps a commercial roof do more than cover the building. It supports energy efficiency and helps maintain a more comfortable interior. For low-slope designs, insulation can also help form the slope needed for drainage. When matched with the right membrane and coverboard, it supports stronger overall performance.

Roof Coatings

Roof coatings provide added protection on certain commercial roofs. They help shield the surface from wear and can reflect sunlight, reducing heat absorption. For eligible systems, roofers often include coatings in a maintenance plan. Over time, the coating supports more consistent roof performance.

Coverboards

Many systems include coverboards as the layer that bridges insulation and the membrane. They help improve impact resistance and add overall toughness to the assembly. Coverboards also smooth out the substrate, which helps the membrane perform better. This can support a more uniform finish across the roof.

Benefits of Choosing GAF Materials

Many property owners turn to GAF roofing products for dependable performance and a wide range of options, making it simpler to build a roof that meets your priorities. With our help, you can narrow your selections to what fits your building and design.

Atmospheric elements like the sun, wind, and seasonal swings can be tough on a roof, which is why you want a durable system. Layered systems are designed to handle that kind of exposure more consistently. When qualified roofers install the entire system, warranty options can provide added reassurance.

We help homeowners in East Detroit and Ann Arbor choose GAF roofing materials that match their roof and their long-term priorities. We also explain how each layer supports the final result.

Proper Installation And Product Compatibility

Materials alone do not guarantee a strong roof. Roofers must keep layers aligned, seal transitions at critical points, and use fastening patterns that fit the system. Underlayment needs to be paired correctly with the shingles above it. Ventilation must also match the attic conditions and the roof design. Our proper installation ties the entire system together.

Compatibility also matters on commercial roofs. Membranes, insulation, and coverboards must work together. We design our installation system to reduce stress on seams and ensure proper drainage. When you work with John McCarter Construction, you get guidance from a team of expert roofers who understand system design.
