A straightforward single-story asphalt shingle roof with few penetrations can finish in a single day; steep-pitch roofs, multiple valleys, or a full deck replacement push that to two or three. Permit turnaround and material lead time usually add more calendar days than the install itself. **Do I need a permit to replace my roof in Boise?** Yes. Boise requires a building permit for reroofing even though it isn't new construction — the fee is valuation-based, roughly $70.76 plus $12.71 per $1,000 of valuation over $2,000. Homeowners often assume reroofing is permit-exempt; it isn't, and we pull it as part of the job rather than leaving it to you. **Is a full tear-off always necessary, or can you roof over the old layer?** Code allows a maximum of two roofing layers, so a roof-over is sometimes technically legal — but we don't recommend it. A tear-off is the only way to actually inspect and fix deck damage underneath, and a second layer traps heat and moisture against the new shingles, shortening their life. If your roof is already on its second layer, a tear-off is required, not optional. **What roofing material handles Boise's climate best?** Architectural asphalt shingles rated for high wind are the standard choice and the best value for most homes. Metal roofing costs more up front but handles the valley's UV exposure and thermal cycling with less long-term wear. The honest answer depends on your budget, roof pitch, and how long you plan to stay in the home — we'll walk through the trade-offs at the inspection, not push one material regardless of your situation. ## Signs you need this - 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 - Roof is 20+ years old and was installed during the 1990s–2000s building boom
