Census and NOAA figures for the city of Thornton in Adams County, not the metro, with a source for each.
The median home in the city of Thornton was built in 1997, newer than the U.S. median of 1980 and newer than the Colorado median of 1988.1 Most of Thornton's housing is recent: only 22% of units predate 1980 (U.S. 50%) and 18% were built since 2010.1 A large share of newer homes means many systems are still inside a warranty; checking that comes before any repair quote. Owner-occupied and rented homes in Thornton are of similar age: median build years 1997 and 1998.1
Housing in Thornton is mostly detached single-family: 62% of units, with 20% in buildings of five or more units.1 A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. 71% of occupied homes in Thornton are owner-occupied (66% statewide).1 The median owner-occupied home in Thornton is valued at $517,500 (ACS), close to the Colorado median of $539,400.1
Winters are long: the Denver-Stapleton station averages 156 nights a year at or below 32°F and 62 at or below 20°F.2,3 Long winters put freeze-thaw, ice dams and snow load at the center of roofing and masonry decisions. Summers bring about 42 days a year at or above 90°F.2,3 Annual precipitation is low, about 15 inches.2,3 Low rainfall shifts the wear to UV and heat, which age finishes and sealants.
Snowfall averages about 49 inches a year.2,3 Real snowfall means ice-and-water membrane, attic ventilation and roof load are standard parts of a roofing scope. Heating dominates the year: about 5,765 heating degree days against 813 cooling degree days (base 65°F).2,3 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope.
Thornton sits in IECC climate zone 5B (Cold).4 Building permits in Thornton are normally issued by the city building department.5,6
