Impact of Weather Conditions on Commercial Roofing

Commercial Roof Repair

Weather conditions play a crucial role in the longevity and performance of commercial roofing systems. From scorching summers to freezing winters and everything in between, each type of weather poses unique challenges and considerations for maintaining the integrity of your commercial roof. Understanding these impacts can help property owners and managers make informed decisions regarding maintenance, repairs, and materials. Here’s how different weather conditions affect commercial roofing:

Heat and UV Radiation

Impact: Intense heat and UV radiation can accelerate the deterioration of roofing materials over time. This is particularly true for roofs exposed to direct sunlight for extended periods, such as those in hot climates or with southern exposures.


  • Material Choice: Opt for roofing materials with high reflectivity and emissivity to reduce heat absorption and minimize thermal expansion and contraction.
  • Coatings: Apply UV-resistant coatings to protect roofing membranes from degradation and extend their lifespan.

Cold and Freezing Temperatures

Impact: Cold weather can cause roofing materials to contract, which may lead to cracking, splitting, or other forms of damage. Additionally, freezing temperatures combined with moisture can result in ice dams and frost heave, further compromising the roof’s integrity.


  • Insulation: Ensure proper insulation to prevent heat loss and reduce the risk of ice dams forming along roof edges.
  • Winter Maintenance: Schedule regular inspections and promptly address any signs of damage or leaks caused by freezing temperatures.

Rain and Moisture

Impact: Excessive rain, snowmelt, or prolonged exposure to moisture can lead to ponding water, leaks, and mold growth. Poor drainage systems or clogged gutters exacerbate these issues, potentially causing structural damage over time.


  • Roof Slope and Drainage: Maintain proper roof slope and ensure effective drainage to prevent ponding water and minimize the risk of water infiltration.
  • Waterproofing: Apply waterproof membranes and sealants as part of regular maintenance to protect against moisture penetration.

Wind and Storms

Impact: High winds, hurricanes, and severe storms can lift roofing materials, tear off shingles or membranes, and damage flashing and other roof components. Wind-driven debris can also puncture or dent roofs, leading to leaks and structural compromises.


  • Securement: Use wind-resistant roofing materials and ensure proper installation techniques to withstand high wind speeds.
  • Post-Storm Inspections: Conduct thorough inspections after severe weather events to identify and address any storm-related damage promptly.

Hail and Impact Damage

Impact: Hailstorms can cause significant damage to commercial roofs, depending on the size and velocity of the hailstones. Impact damage may result in punctures, dents, and granule loss on roofing materials, compromising their waterproofing capabilities.


  • Impact-Resistant Materials: Consider impact-resistant roofing materials such as metal or certain types of shingles that are designed to withstand hail damage.
  • Insurance Coverage: Review your insurance policy to understand coverage for hail damage and ensure prompt filing of claims if necessary.

Maintaining a commercial roofing system involves understanding and mitigating the impacts of various weather conditions. Regular inspections, proactive maintenance, and choosing the right roofing materials are crucial steps in ensuring the longevity and performance of your roof. By addressing weather-related challenges promptly and effectively, property owners and managers can protect their investments and maintain a safe and secure environment for occupants and assets within commercial buildings. Consulting with a professional roofing contractor can provide further guidance on weather-specific strategies to optimize the durability and resilience of your commercial roof.
