How They Differ From Three-Tab Shingles
Traditional three-tab shingles are a single, flat layer with a uniform, repeating pattern. Architectural shingles laminate multiple asphalt layers together, creating varied tabs and shadow lines that mimic the look of wood shake or slate.
That extra material does more than improve appearance. Key practical differences include:
- Weight and thickness — more asphalt and fiberglass per shingle means better resistance to cracking and tearing.
- Wind rating — most architectural shingles are rated for higher wind speeds than three-tab products.
- Lifespan — they are generally engineered to last longer under repeated weather stress.
Why They Hold Up in the Inland Northwest Climate
Roofs around Spokane and North Idaho take a beating: heavy winter snow loads, repeated freeze-thaw cycles, ice dams along the eaves, summer hail, and gusty wind off the Palouse and mountains. The layered construction of architectural shingles is well suited to this punishment.
- Freeze-thaw resistance — thicker shingles flex less and are less prone to the cracking that thin, brittle shingles suffer when temperatures swing above and below freezing.
- Wind and hail — the heavier laminate stays sealed down better and shrugs off impacts that can bruise or crack lighter shingles.
- Snow shedding — a dimensional surface combined with proper installation helps the roof shed snow and channel meltwater toward the gutters.
What to Pair Them With
Architectural shingles perform best as part of a complete system, not on their own. In our climate that means a quality underlayment, a self-adhering ice-and-water barrier along the eaves and valleys to defend against ice dams, and balanced attic ventilation to keep the roof deck cold and reduce ice-dam formation in the first place.
If your current roof is aging, curling, or losing granules, a full roof replacement with architectural shingles and the right accessories is often the most durable long-term choice for an Inland Northwest home.
Are They Worth the Extra Cost?
Architectural shingles typically cost more than three-tab, but homeowners usually find the difference worthwhile because of the longer service life, stronger wind and weather performance, and improved curb appeal. They are also the standard for most manufacturer warranty programs.
As a GAF Master Elite contractor, DG Contracting installs architectural shingles to manufacturer specifications and backs the workmanship with a 25-year warranty. The right product still depends on your home, budget, and roof design.
