TUCSON, Ariz., Jan. 19, 2026 /PRNewswire/ -- West Coast Roofing, LLC, a premier roofing contractor serving the Arizona community, has issued a public advisory regarding a silent but damaging phenomenon known as "thermal shock." As winter temperatures settle across the state, the company highlights the significant risks associated with the drastic temperature fluctuations that characterize Arizona winters.

Thermal shock occurs when roofing materials are subjected to rapid cycles of expansion and contraction. In the high desert climate of Arizona, it is common for daytime temperatures to remain mild, while nighttime lows drop significantly, often nearing freezing. This extreme daily variance places immense stress on roof systems. West Coast Roofing, LLC advises that over time, this repetitive movement causes materials to warp, crack, or split, ultimately compromising the structural integrity of the roof.

Identifying the Risks of Rapid Temperature Changes

While many homeowners associate winter roof damage with precipitation, the stress of thermal shock often goes unnoticed until visible leaks appear. Flat roofs, which are prevalent in Arizona architecture, are particularly susceptible, as are the underlayments beneath tile roofs. When materials become brittle due to age and thermal stress, they lose the ability to flex, leading to fractures that allow water infiltration.

West Coast Roofing, LLC, notes that metal flashings and roof membranes often expand and contract at different rates. This differential movement can cause seams to separate or pull away from walls and vents. If left unchecked, these small openings become entry points for moisture during winter rains.

Preventative Maintenance is Key

The company emphasizes that proactive maintenance is the most effective defense against thermal shock. Routine inspections allow professional roofers to identify early signs of stress, such as hairline cracks, blistering on flat roofs, or displaced tiles. Addressing these minor issues before they escalate into major failures helps homeowners avoid costly emergency repairs. West Coast Roofing, LLC, encourages residents to prioritize professional evaluations during the winter months to ensure their property remains protected.
