Denver's weather swings hard: dry, sunny winter days broken by arctic cold snaps, heavy wet spring snow, and summer afternoons with hail and downpours. Downtown buildings, with large roofs, exposed garages and dense piping, feel all of it. Use this calendar as a starting point and adapt it to your building's systems, vendor contracts and history of problems.

Through the year

September
Roof inspection and repairs before freezing weather. Clear drains and scuppers. Check curtain wall sealant and weep holes.
October
Service dry-pipe sprinkler systems and drain low points per the fire protection vendor. Test garage heaters and heat-trace. Shut and drain exterior hose bibbs.
November
Walk unheated spaces: garages, stair penthouses, loading docks. Confirm thermostats in vacant suites are not set too low.
December to February
Before forecast cold snaps, check vulnerable areas and keep doors to unheated spaces closed. Monitor sump pumps and garage drains during thaws.
March to April
Heavy wet snow season. Watch roof drains and rooftop equipment. Inspect for winter damage to flashing and parapets.
May to August
Hail and thunderstorm season. Keep temporary roof cover materials on hand. Inspect roofs after any significant hail.

FAQs

Is leak detection worth adding to an older downtown building?

Many owners find it useful in high-risk spots: under water heaters, in pump rooms, near tenant kitchens and above server rooms. The value depends on someone receiving and acting on the alert, including at night and on weekends.

When should roof inspections happen in Denver?

Commonly in fall before freezing weather and again after any significant hail or wind event. Spring is a good time to check for winter damage to flashing and drains.
