Architectural vs 3 Tab Shingles: Which Is Better for Idaho Homes?

Architectural shingles are the better choice for most Idaho homes. They are thicker, carry higher wind ratings, and typically last close to a decade longer than 3 tab shingles, which are flat, lighter, and the most affordable asphalt option on the market. Dodd Roofing and Exteriors installs architectural shingles on the large majority of Treasure Valley roofs because Idaho sun, foothills wind, and summer hail wear a thin shingle out fast.

What Is a 3 Tab Shingle?

A 3 tab shingle is a single flat layer of asphalt cut with two notches, so each strip reads as three tabs once it is on the roof. Every course looks identical, which gives the roof a flat, uniform, slightly striped look. They weigh less, install quickly, and cost the least of any asphalt product. Most Treasure Valley homes built before the mid 1990s started out with them.

What Makes an Architectural Shingle Different?

Architectural shingles, also called dimensional or laminate shingles, bond two or more layers of asphalt together. The extra layer adds weight and thickness, which is where the shadow lines and the wood shake look come from. That same thickness is what resists wind lift, granule loss, and impact. Manufacturers back them with longer limited warranties, and most Class 4 impact rated products are built on an architectural base.

Which Holds Up Better in Treasure Valley Weather?

Architectural, and the gap is not small here. Summer surface temperatures on a Boise roof soften asphalt every afternoon, and a thinner mat dries out and curls sooner. Wind coming down out of the foothills catches tab edges first, so blow offs on 3 tab roofs usually start along rakes and ridges. Hail bruises a single layer mat more easily than a laminated one. We see 3 tab roofs here reach the short end of their rating while architectural roofs run closer to the full term. Our guide to the best roofing material for Treasure Valley homes covers metal and tile as well.

Do Architectural Shingles Cost More?

Yes, though less than people expect. The shingle itself runs meaningfully more per square, but material is only part of a roof price. Tear off, underlayment, flashing, ventilation, disposal, and labor stay the same either way, so the upgrade usually adds a modest percentage to the total job while adding years to the roof. Spread over the extra life, architectural is the cheaper roof. Our Boise roof replacement cost guide walks through how the rest of the estimate breaks down.

Are 3 Tab Shingles Ever the Right Choice?

Sometimes. A detached garage, a shed, a rental you plan to sell soon, or a repair that has to match an existing 3 tab roof are all fair uses. They also still show up on new construction where the builder priced the roof tight. If your house has 3 tab shingles now and they are past 15 years, plan on the upgrade at replacement instead of matching what is there.
