Shingle Roofing Boise is a roofing company serving Boise and the Treasure Valley, and architectural shingle roof replacement is one of the services we handle most. This page covers what the work involves here specifically — the climate, the code, and what it costs — rather than what it involves in general.

What we do on the first visit

The first visit is an inspection, not a sales call. We walk the roof with you, check the deck from the attic side where we can, count valleys and penetrations, and note the pitch and how much staging or safety equipment the job needs. We confirm whether any prior layers are on the roof already — code allows a maximum of two before a full tear-off is required — and then you get a written per-square price with tear-off and any deck repair as separate lines.

If we think repair is the better spend than replacement, or a different material suits your situation better, we say so on that visit — including when it means the smaller job for us.

What's included

On-site inspection and a written per-square price before any work starts
Full tear-off to the deck — never a shingle roof-over on a second layer, past the two-layer limit code allows
Deck inspection and replacement of any rotten or delaminated sheathing, priced as its own line
Ice-and-water shield at eaves, valleys, and penetrations; synthetic underlayment across the field
Drip edge and new flashing at chimneys, walls, and vents — not reused off the old roof
Installation held to the manufacturer's temperature spec so the self-sealing adhesive strip actually bonds
Balanced ridge and soffit ventilation checked and corrected, not just matched to what was there
Full site cleanup with a magnet sweep for dropped nails and haul-away of the old shingles

What this costs in Boise

Architectural Shingle Roof Replacement runs $350–$650 per roofing square installed in this area. 2026 published Boise-area installed pricing for architectural/dimensional asphalt shingle (legacyroofingidaho.com). The things that move a job up its range are tear-off, how much deck repair is needed, pitch, and how many valleys and penetrations your roof has. If you want a number before you call, the roof cost calculator will get you close.

Shingles curling, cupping, or losing granules in patches
Daylight visible through the roof deck from the attic
Soft or spongy spots when walking the roof
Missing shingles or exposed nail heads after a wind event
Water stains on interior ceilings, especially near valleys or chimneys

Questions

Architectural Shingle Roof Replacement questions

How long does an architectural shingle roof replacement take in Boise?

Most single-family homes take one to two days once material is on-site, weather permitting. Steep-pitch or heavily-cut roofs (multiple valleys, dormers, chimneys) can run closer to three. We give you a specific day estimate at the inspection, not a generic range.

What's the real difference between architectural and 3-tab shingles?

Architectural shingles are made from two or more laminated layers, giving them a heavier, dimensional look and a higher wind rating — typically 110-130 mph versus a 3-tab's flatter profile and lower rating. They also carry longer manufacturer warranties. The tradeoff is cost: architectural runs roughly $350-650 per square installed in this market versus $250-400 for 3-tab.

Which shingle brands do you install?

We install GAF, Owens Corning, CertainTeed, and Malarkey architectural lines. Each has real differences in algae resistance, wind-rating technology, and warranty terms worth understanding before you pick one — see our brand comparison guide for specifics.

Will a repair patch ever match my roof's original color exactly?

Not perfectly, and we won't tell you otherwise. Asphalt shingles fade with UV exposure over time, so a patch installed years after the original roof will usually look slightly different at first and blend somewhat as it weathers. We'll tell you honestly how noticeable it's likely to be before we do the work.

Do you charge for an estimate?

No. Estimates are free across Boise and the Treasure Valley, including the drive. We walk the roof with you, check the deck from the attic side where we can, and hand you a written per-square price with tear-off and any deck repair broken out as their own lines.
