Flat roofs are common on both residential and commercial buildings throughout Long Island, thanks to their modern look, usable space, and affordability. However, flat roofs require routine maintenance to avoid drainage problems, leaks, and structural issues.
At ELED Construction, we specialize in flat roof installation, repair, and maintenance. If your home or business has a flat roof, this guide will help you understand how to protect your investment with proactive care.

Why Flat Roof Maintenance Matters
Unlike sloped roofs, flat roofs don’t naturally shed water. Without regular upkeep, water can collect, leading to:
-
Ponding and standing water
-
Roof membrane deterioration
-
Leaks and interior water damage
-
Mold, mildew, and insulation rot
-
Shortened roof lifespan
Routine inspections and preventive maintenance are key to avoiding these problems and extending the life of your roof.
1. Inspect Your Roof Regularly
Perform visual inspections at least twice a year — ideally in spring and fall — and after major storms. Look for:
-
Cracks, blisters, or bubbling in the membrane
-
Pooling water or slow drainage
-
Loose flashing or sealing around vents and edges
-
Soft spots that suggest water saturation
-
Dirt or debris buildup
Pro tip: Hire a professional for a thorough inspection if you’re unsure what to look for.
2. Keep the Roof Clean
Leaves, branches, and debris can clog drains and gutters, causing water buildup. A clean flat roof ensures proper water flow and prevents mold or decay.
Clean your roof by:
-
Removing organic material by hand or with a soft broom
-
Washing away dirt and residue (never use high-pressure washers)
-
Clearing all drains and scuppers
Schedule cleanings at least twice a year, and more frequently if your building is near trees.
3. Check and Maintain Drainage Systems
Drainage is the most important part of a flat roof. Even a slight backup can cause ponding water, which weakens the roof structure over time.
-
Make sure internal drains and exterior scuppers are clear
-
Ensure downspouts and leader pipes are working properly
-
Look for signs of rust or clogs
-
Test water flow with a garden hose
4. Repair Minor Issues Promptly
Small cracks or punctures in your flat roof can quickly become major leaks. Common causes include:
-
Foot traffic
-
HVAC equipment
-
Weathering and UV damage
-
Thermal expansion and contraction
Have any issues repaired quickly by a professional roofer to avoid moisture intrusion.
5. Monitor for Ponding Water
Ponding is when water sits on your roof for more than 48 hours. Even small pools of water can degrade the roofing material, especially in cold or humid conditions.
If you see ponding water:
-
Check for clogged drains
-
Look for low spots in the roof surface
-
Ask a professional about re-pitching or installing tapered insulation
6. Inspect Flashing and Seals
Flashing is the protective barrier between the roof membrane and vertical structures like vents, skylights, or parapet walls. Look for:
-
Loose or lifted flashing
-
Rust or corrosion
-
Gaps or failing caulking
Proper flashing ensures water doesn’t seep into the roof seams or building interior.
7. Limit Foot Traffic
Flat roofs are often used for HVAC access or storage, but foot traffic can damage the surface over time. To reduce wear and tear:
-
Install walk pads or pavers
-
Limit rooftop access to necessary personnel
-
Clearly mark walkways and mechanical areas
8. Schedule Annual Professional Maintenance
Even if everything looks fine to the untrained eye, annual flat roof maintenance by a licensed contractor like ELED Construction ensures early detection of hidden problems.
