Detroit averages 30 freeze-thaw cycles per winter. Water infiltrates tiny gaps in skylight flashing during fall rains. When temperatures drop below freezing, that water expands and widens the gap. By spring, what started as a hairline crack becomes a channel for water to pour through during heavy rain. Roof window leaking problems in Detroit often trace back to winter ice damage that went unnoticed until the first major spring storm. The constant temperature swings stress sealants and metal flashing faster than in stable climates.
Peak Roofing Detroit has repaired leaking skylights in neighborhoods from Rosedale Park to the Villages since our company started. We understand how Detroit's older homes were built and where skylights typically fail. Many roofers from outside the metro area do not account for our clay soil movement or the way our winter ice dams form. Local expertise matters when diagnosing skylight leaks because the failure patterns here differ from drier or warmer regions. We use installation methods proven to survive Michigan winters.
