There are a few types of residential roofing materials we offer including:
- Asphalt 3-Tab
- Asphalt Archetectural, also called dimensional
- Standing seam galvalume metal roof
Here, we compare the two types of asphalt and give some information about each option.
Because 3-tab shingles and architectural shingles are both asphalt shingles, they are similar in composition. They are both made with asphalt and adhesives, and as well as granules for the outermost layer and a fiberglass mat for the backing.
3-tab shingle
Physical composition
The primary differences between the two are the amount of material used, as well as the overall quality of each product. Essentially, architectural shingles are more substantial than 3-tab shingles. In fact, they are about 50 percent heavier than the 3-tab kind. The base mat on an architectural shingle is thicker than that on a 3-tab shingle. This makes the architectural shingle a sturdier roofing material. Architectural shingles also comprise stronger adhesives, and they have more granules on their top surface. They are also made from asphalt of a finer quality than 3-tab shingles.
Architectural or dimensional shingles
Aesthetics
These two types of asphalt shingles also differ in their appearance. 3-tab shingles are flat, and they have a single tab shape and size. They are uniform, which gives them a flat look.
Architectural shingles are also referred to as dimensional shingles. This is because they provide a more dimensional look to the roof. Each shingle appears more dimensional because it is; multiple layers of materials adhere to the base. These shingles can be made to resemble cedar shakes, which may add much to a home’s curb appeal. They can also be constructed to simulate the look of slate, but without the added weight that slate would bring to a roof.
Wind Ratings
The two shingle types yield different wind resistance ratings. While there may be some subtle variations, 3-tab shingles are generally rated for winds of up to approximately 60 miles per hour (mph). Since architectural shingles are thicker and of a higher quality, it makes sense that they have higher wind ratings than 3-tab shingles. They typically are rated for winds of between 80 mph and 120 mph.
Lifespan
Because of their durability and high-quality composition, architectural shingles generally have a longer lifespan than the 3-tab variety. They stand up better to weather conditions such as heat, snow, ice, rain, and strong winds. Their average lifespan is about 18 to 20 years. However, they may last up to 30 years under optimal conditions. When 3-tab shingles are exposed regularly to severe weather, they may last about 7 to 10 years. In areas with mild climates, they may last as long as 12 to 15 years.
Warranty
The warranties that come with these shingles are reflective of their overall value. Since 3-tab shingles have a shorter lifespan, they have shorter warranties. 3-tab shingles generally have warranties of 25 to 30 years. Architectural shingles typically come with warranties of 50 years, and some of them may even have lifetime warranties.
Cost
The overall cost of both types of shingles is relative. Although 3-tab shingles may be less expensive to install, they usually need to be repaired and replaced sooner than architectural shingles.
So, the suitability of each of these shingle varieties is also relative. 3-tab shingles are more economical in the short term, so they may be ideal for rental properties and budget homes. Architectural shingles may be a better choice for high-end homes, as well as for homeowners who value aesthetics and longevity over lower initial costs.
Metal Standing Seam Roofs: Galvalume
We sell galvanized metal products as well. Our main metal roof product at 3 Rivers Roofing is painted or bare 24-gauge Galvalume coils and sheets used on our standing seam roof. Galvalume standing seam combines three of the most important metals used in roofing today—steel, aluminum, and zinc. Manufacturers begin with a carbon steel base sheet that is then continuously hot-dipped with aluminum and zinc alloys until it reaches a coating consisting of 55% aluminum, 43.4% zinc, and 1.6% silicone. This galvalume roof lasts 60+ years.
