Flat roofs are durable and cost-effective—but only when properly maintained. If neglected, they’re more prone to pooling water, blistering, and costly leaks. Here’s how property owners in New Jersey can extend the life of their flat roofing system and avoid unexpected repairs.
🧽 1. Clean Off Debris Every Season
Leaves, branches, and dirt trap moisture. Over time, this leads to mold growth and structural damage. Schedule a flat roof cleaning at least 3–4 times per year, especially in the spring and fall.
🔍 2. Perform Biannual Inspections
Check for:
Standing water or ponding after 48 hours of rainfall
Soft spots or blisters under the membrane
Loose flashing or damaged seams
Cracks near penetrations (vents, pipes, skylights)
Tip: Have a licensed roofer inspect your roof each spring and fall, and after any major storm.
💧 3. Reapply Roof Coating as Needed
Elastomeric coatings or aluminum-based sealants help waterproof your flat roof. Re-coating every 5–7 years can add up to 10 extra years to your system.
🧰 4. Keep Drains & Scuppers Clear
Backed-up drainage is a major cause of leaks. Ensure internal drains, gutters, and scuppers are always clean and flowing properly—especially after storms.
⏳ 5. Know the Warning Signs of Aging
If your flat roof is over 15 years old and you’re noticing:
Water stains inside the building
Bubbling or tearing on the surface
Inconsistent heating/cooling bills
…it may be time to plan for replacement within the next 1–2 years.
📍 New Jersey Property Owner Tip:
Snow and ice in winter can accelerate roof damage. If snow sits for more than 3 days, consider a professional snow removal to avoid stress and water intrusion.
