Local know-how

Homes in Centennial: what we see

The Colorado climate and what it does to a house.

The Front Range sees big temperature swings, strong high-altitude sun, heavy spring snow and some of the worst hail in the country.

Chimneys & fireplaces

Daily freeze and thaw opens cracks in the crown and mortar joints, and water that gets in freezes again overnight. Crowns and caps take the most damage.

Roofs

Hail bruises shingles and dents metal, and the damage is easy to miss from the ground. Strong sun ages shingles faster at altitude.

Gutters

Snow melts by day and refreezes in the gutters at night, so ice dams and pulled-off gutters are common after a heavy storm.

Attic insulation

Cold winters and warm summers both push on the attic. More insulation keeps snow on the roof from melting into ice dams and cuts the heating bill.
