Your commercial roof is the first line of defense against New Jersey’s unpredictable weather, from intense summer storms to heavy snow in winter. But when small issues go unnoticed, they can quickly turn into expensive damage—leaking into offices, halting operations, and even violating lease agreements.
At Boundless Roofing & Chimney, we help property owners across the state catch problems early. Here are the 9 most important signs your commercial roof needs immediate repair—and what to do about them before it’s too late.
1. Visible Water Ponding
If water sits on your flat roof longer than 48 hours after a storm, that’s called ponding. While common, it’s a serious issue.
Why it’s urgent:
Standing water accelerates membrane breakdown, increases leak risk, and adds weight stress to the structure—especially dangerous in winter.
Immediate action: Have drainage checked and consider installing tapered insulation or correcting the slope.
2. Ceiling Stains or Interior Leaks
If tenants or employees notice stains, watermarks, or dripping water inside the building—especially near vents, walls, or ceiling panels—it means water is already breaching the roof system.
Why it’s urgent:
Moisture inside the building can damage insulation, electrical systems, and drywall—and lead to mold growth.
Immediate action: Schedule a leak detection and emergency patch with a roofing expert.
3. Cracks, Blisters, or Bubbles on the Roof Surface
Flat roof membranes (like EPDM, TPO, or BUR) are designed to be smooth and seamless. If you see bubbles, cracks, or “blisters,” it means water or air has gotten trapped under the surface.
Why it’s urgent:
These areas can rapidly peel open, especially during freeze-thaw cycles or high UV exposure, exposing your structure to water damage.
Immediate action: Boundless Roofing & Chimney can repair damaged sections or reinforce vulnerable zones with new membrane.
4. Loose or Damaged Flashing
Flashing is used to seal joints, edges, and roof penetrations like vents and HVAC units. If it’s missing, cracked, or lifting, water can flow straight into the roof system.
Why it’s urgent:
Flashing failures are one of the top causes of roof leaks in commercial buildings.
Immediate action: Re-seal or replace flashing immediately before the next storm.
5. Mold, Mildew, or Unpleasant Odors Indoors
Mold or mildew in upper floors, musty smells, or frequent HVAC issues could mean water has entered your roofing insulation.
Why it’s urgent:
Mold is a health hazard that can spread quickly and cause liability risks or code violations.
Immediate action: Call for a full moisture scan and consider replacing affected roofing layers and insulation.
6. Increased Energy Bills
A sudden or consistent spike in energy costs can indicate your roof is no longer properly insulating your building.
Why it’s urgent:
Heat loss or gain through the roof means HVAC systems must work harder, increasing wear and tear.
Immediate action: Inspect insulation and membrane integrity; apply a reflective coating or replace degraded sections.
7. Sagging or Uneven Roof Deck
If parts of the roof appear to dip, buckle, or feel soft underfoot, you may be experiencing structural deck failure.
Why it’s urgent:
This can signal rotting wood, corroded metal decking, or trapped water—posing collapse risk.
Immediate action: Avoid foot traffic in the area and call a professional for a structural assessment.
8. Gutter or Drain Overflow
If water pours over the side of your building during rain—or pools near downspouts—your drainage system is clogged or undersized.
Why it’s urgent:
Improper drainage increases the risk of ponding, leaks, and foundation erosion.
Immediate action: Clean all internal drains, scuppers, gutters, and check for blockage from debris or ice.
9. Past Repairs That Keep Failing
If you’ve had to fix the same section of roof more than once in the past 1–2 years, it’s no longer just a patch job—it may require structural repair or replacement.
Why it’s urgent:
Repeat leaks indicate widespread membrane breakdown or installation errors.
Immediate action: Consider a full inspection and long-term solution plan with our team.
