Summerland's station numbers
Summerland sits on a natural bench on the west side of Okanagan Lake, under Giant's Head Mountain. Its climate table, from the Summerland station's 1981–2010 normals, shows 118.8 days a year with measurable precipitation and 100.8 days with rain. January averages a high of 1.2 °C and a low of −4.1 °C, and the coldest reading on record is −30.0 °C.
Heat and sun on the Summerland benches
July averages a high of 28.4 °C. The all-time record in the table is 44.7 °C, in June; the July record is 40.0 °C. With under 340 mm of precipitation in a year, a roof here wears out from sun far more than from water.
Asphalt dries and sheds its granules; cedar splits. Interlock® aluminum shingles have neither material in them, and aluminum cannot rust.
Wildfire and the District of Summerland
The Bald Range wildfire spread quickly on the evening of August 7, 2026, and the whole town was evacuated. CP24 reported about 150 structures damaged or destroyed, and the District lifted its last evacuation orders on October 1, 2026.
The District's wildfire risk reduction runs under its Community Wildfire Resiliency Plan. In early 2024 that included thinning, pruning and pile burning on about 100 hectares of Crown land just east of McLennan Road. The District has also offered free FireSmart Home Assessments, booked by email at ryan@summerlandfs.ca.
Embers and the edges of a Summerland roof
We offer Class A Fire Rated Available, as a complete assembly, and the aluminum does not ignite. No roof is fireproof. FireSmart BC's homeowner's manual sorts roofing into Class A, B and C, and its advice for the rest of the house is plain:
- Take dry leaves and needles out of the gutters on a regular schedule
- Cover attic and soffit vents with 3 mm metal mesh
- Keep anything that burns at least 1.5 metres from the walls
Snow on a Summerland roof
The station averages 54.0 cm of snow a year over 20.7 snowy days. Snow comes off a metal roof in one go, so snow guards are planned at the estimate over entries, decks and the driveway.
Ice damming is caused by attic heat melting snow at the eaves, and it is a warranty exclusion, so we look at insulation and venting too. The roof is warranted for wind to 193 km/h (120 mph), installed to manufacturer specification.
Summerland questions, answered
How hot does it get in Summerland?
Hot enough to matter for a roof. The Summerland station's normals give a July average high of 28.4 °C, and the record in the table is 44.7 °C, set in June. Aluminum is not damaged by that heat. Pick a colour you like in the sun; the material itself does not dry out or crack.
Does the District of Summerland help with FireSmart?
Yes. In February 2026 the District announced free FireSmart Home Assessments with a qualified FireSmart service provider, giving practical recommendations for the home and property. They are booked by email at ryan@summerlandfs.ca. The roof is one part of what an assessment looks at.
Do I need snow guards in Summerland?
Usually over doors, decks and parking. The station averages 54.0 cm of snow a year, and a metal roof sheds it all at once rather than letting it melt where it fell. We mark where guards belong when we measure the roof, and they appear on the written estimate.
