Commercial roofs in Long Island face a unique mix of seasonal weather, from summer heat and humidity to freezing winters and coastal storms. These conditions can take a serious toll on your building’s roofing system if left unaddressed.

At ELED Construction, we’ve seen firsthand how minor issues quickly turn into major problems—leading to costly repairs or full roof replacements. Whether you manage a warehouse, retail building, or office space, understanding these common roofing problems can help you protect your investment.

1. Ponding Water

What it is:

Flat and low-slope commercial roofs are prone to water accumulation after rain. If the water sits for more than 48 hours, it’s considered “ponding.”

Why it’s dangerous:

Ponding adds weight to the structure and degrades the roofing membrane over time. It can lead to leaks, mold growth, and even structural failure.

Prevention tips:

  • Ensure proper drainage design (gutters, scuppers, interior drains)

  • Schedule biannual inspections to detect low spots

  • Install tapered insulation to redirect water flow

  • Clean drains regularly to prevent clogs


2. Damaged Flashing

What it is:

Flashing is the material (often metal) installed around roof edges, vents, chimneys, and HVAC units to keep water out.

Why it’s dangerous:

When flashing becomes loose, cracked, or corroded, water can seep into seams and roof penetrations, leading to interior leaks.

Prevention tips:

  • Include flashing checks in routine inspections

  • Reseal or replace damaged flashing promptly

  • Use high-quality flashing materials designed for commercial use

  • Limit foot traffic near flashings to prevent accidental damage


3. Membrane Punctures or Blistering

What it is:

Commercial roofing systems like TPO, EPDM, or modified bitumen are durable—but not invincible. Punctures from foot traffic, debris, or tools, and blisters from trapped air or moisture are common.

Why it’s dangerous:

Compromised membranes let water into the insulation layer and building structure, reducing energy efficiency and causing hidden damage.

Prevention tips:

  • Limit rooftop access to trained personnel

  • Use walk pads in high-traffic areas

  • Inspect after storms or maintenance visits

  • Repair small punctures before they worsen


4. Poor Drainage System Maintenance

What it is:

Commercial roofs rely on drains, gutters, and scuppers to remove water. These systems easily get clogged with debris like leaves, dirt, or roofing material fragments.

Why it’s dangerous:

Blocked drainage leads to standing water, roof deterioration, and even ice dams in winter.

Prevention tips:

  • Clean all drainage components at least twice a year

  • Inspect after storms or seasonal changes

  • Install protective grates or filters to reduce debris buildup

  • Repair sagging gutters or damaged downspouts promptly


5. Weather-Related Damage

What it is:

Long Island storms, high winds, hail, and heavy snow can damage commercial roofs—ripping off shingles, displacing flashings, and creating membrane tears.

Why it’s dangerous:

Storm damage is often hard to detect from the ground, allowing small leaks to grow unnoticed and voiding warranty or insurance claims.

Prevention tips:

  • Schedule roof inspections after every major storm

  • Document roof condition annually for insurance purposes

  • Install wind- and impact-rated materials suited to Long Island’s climate

  • Keep nearby trees trimmed to prevent branch damage


The Cost of Ignoring These Problems

Neglecting routine maintenance and inspections can lead to:

  • Emergency repairs costing thousands of dollars

  • Damage to inventory, insulation, or structural components

  • Mold remediation and interior restoration expenses

  • Increased energy costs from poor insulation performance

  • Premature roof replacement before the system’s expected lifespan

Routine roof care is a fraction of these costs—and it extends your roof’s durability.
