Chelsea sits in western Washtenaw County, an affluent small city of about 5,467 people (2020 Census) anchored by the Purple Rose Theatre, Jiffy Mix headquarters, and a National Register downtown. Housing stock runs the full range, from 1860s downtown homes to current-build subdivisions on the edges. Roofs here take a beating. Roughly 33 to 36 inches of snow a year. January lows in the low 20s. Freeze-thaw cycles every winter that crack sealant and lift shingle tabs. Spring and summer wind and hail events drive most of the homeowner insurance claims in Michigan, around 40% of all losses (III).
SkyeVantage coordinates asphalt shingle roof replacements in Chelsea end to end. Materials at wholesale cost. Synthetic underlayment, ice and water shield at the eaves and valleys to meet Michigan code, drip edge, ridge cap, and the right ventilation so the shingles you paid for actually last 25-plus years. A Preferred Roofing Network crew handles the tear-off and install. Axium inspects.
One flat fee covers the coordination, the labor, the materials setup, and the dumpster. Everything else is at cost. You see the receipt.
Chelsea has a humid continental climate (Köppen Dfb), the same pattern as the rest of Washtenaw County and the western Ann Arbor area. NOAA 30-year normals for the county:
- Annual snowfall: roughly 33 to 36 inches. Ice damming risk on north-facing eaves through December to March.
- Winter temps: January average in the low 20s°F. Freeze-thaw cycles repeatedly stress sealants, flashings, and shingle adhesion.
- Summer temps: July average in the low 70s°F with regular 80-plus degree days. UV exposure on south and west slopes accelerates granule loss.
- Annual precipitation: roughly 36 inches of rain. Water management at valleys, step flashings, and chimney saddles is non-negotiable.
- Severe weather window: Spring through early fall. Wind, hail, and severe thunderstorms drive most of MI’s homeowner claims.
