At ELED Construction, we specialize in roofing solutions that stand up to the demands of Long Island’s climate. In this post, we’ll explain how the weather impacts your commercial roof and what steps you can take each season to protect your property and extend the life of your roof.

Winter: Ice, Snow, and Freeze-Thaw Damage
Common Threats:
-
Ice dams
-
Snow load stress
-
Freeze-thaw cycles
-
Cracking membranes and flashing
Heavy snow accumulation on flat or low-slope roofs adds weight and creates ponding water when it melts. Ice dams can form when warm air from the building melts snow, which then refreezes at the edges—forcing water underneath roofing materials. Repeated freezing and thawing can also lead to cracks in membranes and flashing.
Prevention Tips:
-
Schedule a fall inspection to ensure your roof is sealed and draining properly
-
Clear snow promptly after heavy storms
-
Ensure proper attic insulation and ventilation to reduce ice dam formation
-
Install snow guards or ice-melt systems if needed
Spring: Storms and Standing Water
Common Threats:
-
Heavy rain
-
Clogged drains and scuppers
-
Wind-blown debris
-
Membrane punctures
Spring storms often bring strong winds and large volumes of rain. If your roof’s drainage system is clogged or damaged, water can pool and begin to wear down the roofing membrane. Flying debris from nearby trees or structures can also cause punctures or tears.
Prevention Tips:
-
Inspect and clean gutters, scuppers, and internal drains
-
Schedule a post-winter inspection for any damage from snow or ice
-
Trim nearby trees and secure rooftop equipment
-
Repair any visible signs of membrane damage immediately
Summer: Heat, UV, and Humidity
Common Threats:
-
UV degradation
-
Heat-induced expansion and contraction
-
High humidity
-
Mold or algae growth
Long Island summers bring intense sunlight and high humidity. UV rays can dry out and crack certain roofing materials over time. Heat causes roofing components to expand and contract, which may loosen seams or flashing. High humidity levels can contribute to mold growth beneath the roof deck if ventilation is poor.
Prevention Tips:
-
Use reflective or energy-efficient roofing materials (like TPO or PVC)
-
Ensure the roof is well-ventilated to reduce heat and moisture buildup
-
Apply UV-protective coatings where appropriate
-
Schedule routine inspections for signs of cracking or membrane separation
Fall: Coastal Storms and Wind Damage
Common Threats:
-
Hurricanes or tropical storms
-
High wind uplift
-
Tree limb damage
-
Gutter blockages from falling leaves
Autumn in Long Island often means powerful nor’easters and hurricanes. Commercial roofs are at risk of wind uplift, where roofing materials are lifted or torn away by strong winds. Debris can clog gutters or fall onto the roof, creating puncture hazards.
Prevention Tips:
-
Schedule a fall inspection before storm season begins
-
Secure flashing, membranes, and rooftop units
-
Install wind-rated materials when replacing or repairing roofs
-
Remove fallen leaves and debris from the roof surface
Why Routine Roof Maintenance Matters in All Seasons
Neglecting your roof between seasons allows minor issues to turn into major repairs. Routine inspections and maintenance can help you:
-
Extend the lifespan of your commercial roof
-
Prevent emergency repair costs
-
Improve energy efficiency year-round
-
Stay compliant with manufacturer warranties and insurance requirements
