Choosing Siding for the Nampa Climate
Every region wears siding out in its own way. For Nampa, with summer highs near 84°F, the main factors are these:
Climate regions run from 1 (cool) to 5 (hot); Idaho sits in region 1.
Wildfire. In fire-prone areas the siding material matters. Fiber cement does not burn, vinyl melts and wood can ignite, so many such areas favor or require ignition-resistant walls.
Cold-weather impacts. Cold makes vinyl stiff and easier to crack when something hits it. Thicker panels survive a winter of shovels, balls and ladders better; fiber cement ignores the cold, but its cut ends must be sealed.
Sliding snow. Snow dropping off a roof can strike lower walls and deck rails hard. Fiber cement or a heavy vinyl panel takes that hit better than a thin one.
Most whole-house siding jobs here happen between the spring thaw and the first hard frost. Vinyl turns brittle and hard to cut cleanly in the cold, which is why few crews install it in midwinter. Nampa is in Canyon County, and most siding crews here cover the wider county. Ask at least one contractor from outside the city for a bid; travel rarely adds much on a whole-house job.

Siding is priced by the square (100 sq. ft. of wall). In Nampa, vinyl runs about $687.95 per square and fiber cement about $1,234.01, materials and labor, before trim and tear-off.
When is removing old siding worth it?
It depends on what is under it. Sound, flat walls can take a new layer; soft spots, stains or bulges mean the old siding should come off, at about $2,010 to $4,010 here.
