Big temperature swings
The National Weather Service notes that Reno's high-desert setting produces large temperature swings from day to night and season to season. Siding expands and contracts with those swings every day. Vinyl moves the most and must be installed loosely enough to slide; panels nailed tight will buckle on warm afternoons. Caulked joints in any material stretch and compress and eventually fail, so plan to inspect and renew caulk regularly.
Freeze-thaw and moisture
NOAA's engineering weather data for the Reno airport records about 123 freeze-thaw cycles a year, and Washoe County's residential design criteria use a 17°F winter design temperature. Water that gets into gaps, unsealed edges or cracks freezes and expands, widening them. Engineered wood and fiber cement need their cut edges handled according to the manufacturer's instructions, and all siding needs proper clearance from the ground and roofs so snow and meltwater don't sit against it. Vinyl becomes more brittle in cold weather and can crack if hit.
Intense sun
Reno's sun is strong at altitude. Paint and factory finishes on south- and west-facing walls fade faster. Lighter colors and quality finishes last longer.
Wind
Strong winds in the Reno area can loosen siding that isn't properly fastened. Manufacturers specify fastening for wind resistance; ask the contractor which wind rating the installation meets.
Wildfire considerations
Parts of the Reno area are near wildland vegetation. In those areas, noncombustible or ignition-resistant siding such as fiber cement, along with ember-resistant vents and good clearance between plants and walls, reduces risk. Check whether local codes require specific materials at your address.
Behind the siding
A new water-resistive barrier, properly flashed windows and doors, and kickout flashing where roofs meet walls protect the sheathing.
Before you hire
Ask Reno siding contractors which product suits your exposure, how they'll fasten for wind, how they'll handle expansion, whether fire-resistant materials are recommended, and what warranties cover. Look up the contractor with the Nevada State Contractors Board.
Choosing a material for Reno
Fiber cement is a strong choice where fire resistance and durability matter. Engineered wood gives a wood look at lower weight and installs quickly. Vinyl is the most affordable but needs careful installation for Reno's temperature swings and becomes more brittle in cold. Ask the contractor to explain how each would perform on your home's sunniest and windiest walls.
Maintenance
Inspect caulk every spring after winter freeze-thaw cycles, touch up paint, and look at the bottom edge of siding for damage from snow and ice. Clear snow away from walls after storms.
Permits
Re-siding may need a permit from the City of Reno, City of Sparks or Washoe County. Ask whether it's included in the price.
Windows and doors
If windows are aging, replace them with the siding so their flashing is integrated and the new siding isn't disturbed later.
