A leaking roof is one of those problems that gets worse the longer you wait. Water doesn’t stay in one place. It moves along rafters, soaks into insulation, and shows up on a wall or ceiling well away from where it actually entered. By the time you notice a stain, the damage behind it is often more extensive than it looks.
If your roof is leaking, here is exactly what to do, in order, from the moment you discover it.
Step 1: Protect Your Interior Right Now
Before you call anyone or do anything else, protect what you can inside. Move furniture and valuables away from the affected area. Place buckets or containers under active drips. Use old towels or tarps to protect flooring.
If water is coming through a ceiling and you can see the drywall bulging, there may be water that has collected above it. Carefully puncture the lowest point of the bulge with a screwdriver to let it drain in a controlled way. This sounds counterintuitive, but it prevents a larger ceiling collapse later.
Once the interior is protected, you can turn your attention to the roof itself.
Step 2: Document the Damage Before You Touch Anything
Before any repairs happen, document everything. Take photos and video of every affected area, including the ceiling stains, any visible damage, and whatever you can safely observe from outside or through an attic access point.
This documentation matters for two reasons. First, it establishes a record of the damage at the time of discovery, which matters if you file a homeowner’s insurance claim. Second, it helps the roofing contractor understand the scope of what they’re walking into before they get on the roof.
Do not attempt to make repairs yourself before documenting. A patched area or removed material can complicate an insurance assessment.
Step 3: Don’t Assume You Know Where the Leak Is Coming From
This is one of the most important things to understand about roof leaks: where water appears inside your home is almost never where it entered the roof.
Water travels. It follows the path of least resistance along structural members, underlayment, and insulation before it shows up as a stain or drip. A leak appearing above a bedroom window may have entered the roof 10 feet away. A drip near a light fixture may be traveling from a penetration on the opposite side of the roof.
This is why attempting a DIY fix is often ineffective. You patch the area above the stain, the leak continues, and you’ve spent money without solving anything. Locating the actual source of a roof leak requires examining the full roof systematically, including the flashing around every penetration, the condition of seams and membrane, and the state of the underlayment.
Step 4: Call a Licensed Roofing Contractor
Once you’ve protected the interior and documented the damage, call a licensed roofing contractor. Not a handyman. Not a general contractor who also does roofing. A contractor who specializes in roofing, is licensed in New York City, and can pull a permit if the scope of work requires one.
The difference matters. A licensed roofer understands the full range of failure points specific to New York’s climate and housing stock. They carry the right insurance. And they’re accountable in a way that an unlicensed handyman isn’t.

What’s Actually Causing Your Roof to Leak
Once a contractor is on the roof, here are the most common culprits they’ll be looking for.
Separated or Failing Seams
On flat roofs, the seams between membrane sections are one of the highest-risk areas. Over time, the adhesive or heat-welded bonds can separate, especially where the roof experiences temperature extremes or foot traffic. A separated seam is a direct water entry point.
Our flat roof repair work in Queens, Brooklyn, and Manhattan regularly involves locating and properly sealing failed seams before they allow further water intrusion into the building.
Damaged or Missing Shingles
On sloped residential roofs, missing or damaged shingles expose the underlayment beneath, which is not designed to handle prolonged direct weather exposure on its own. A shingle roofing issue that looks minor from the ground can be more significant when viewed up close.
Flashing Failures
Flashing is the metal material installed around chimneys, skylights, vents, and roof edges to seal the transition points between the roof and other surfaces. It is one of the most common leak sources on both flat and sloped roofs. Flashing can corrode, pull away from the surface it’s sealing, or was never properly installed in the first place.
Aged or Deteriorated Membrane
Flat roof membranes, including EPDM and TPO systems, have a finite lifespan. A membrane that has become brittle, cracked, or is showing significant surface deterioration is no longer doing its job reliably. At some point, patch repairs stop being cost-effective and a full replacement becomes the better investment.
A roof waterproofing assessment can help determine whether the membrane is salvageable or whether replacement is the more practical path forward.
When Is a Repair Enough? When Do You Need a Replacement?
The honest answer is: it depends on the age of the roof, the extent of the damage, and the overall condition of the system.
A targeted repair makes sense when the damage is localized, the rest of the roof is in good condition, and the repair will realistically last several more years. We tell you honestly when a repair is the right call.
A replacement makes more sense when the roof is approaching or past its expected lifespan, when multiple areas are failing simultaneously, or when the cost of ongoing repairs is approaching the cost of a new roof. Putting money into a roof that’s already at the end of its life is a short-term fix that delays an inevitable expense.
The National Roofing Contractors Association recommends having your roof inspected at least once a year and after any significant storm event. According to the NRCA, early identification of minor problems is one of the most effective ways to extend the useful life of any roofing system.
Frequently Asked Questions
How do I know if my roof is leaking or if it’s a plumbing issue?
Roof leaks and plumbing leaks can look similar from inside the home. A few things to check: does the water appearance correlate with rain events? Is it coming from an area directly below the roof rather than near a pipe or fixture? A roofer and a plumber can each assess their respective systems. If you’re not sure, start with a roof inspection, since roof leaks are more time-sensitive in terms of interior damage.
Can a roof leak fix itself in dry weather?
The leak will stop during dry weather, but the underlying problem does not resolve. The entry point is still there. The next rain event will produce the same result, and the cumulative moisture damage to insulation, sheathing, and interior materials continues to build.
How long can I wait before calling a roofer?
Ideally, you call within the day. Even if it’s not actively raining, water that has already entered the roof system continues to affect the materials around it. The longer you wait, the more extensive the remediation.
Will my homeowner’s insurance cover a roof leak in NYC?
It depends on the cause. Sudden damage from a storm event is typically covered. Leaks resulting from deferred maintenance or normal wear and tear usually are not. Documenting the damage immediately after discovery strengthens any claim you file.
