A vent boot runs $200 to $500. Chimney flashing runs $400 to $1,200. A valley runs $500 to $1,500. Lamar Homes repairs start at $625, and the number that matters comes from finding what actually failed rather than from any table.
The table
Roof leak repair cost by what actually failed
What has failed
Published range
Why it costs that
Vent pipe boot
$200 – $500
One part, one hour, no metalwork. The most common leak and the cheapest.
A few missing or cracked shingles
From $150
Cheap if it is genuinely only shingles and the decking is dry.
Chimney flashing
$400 – $1,200
Shingles lifted, old flashing out of the mortar joint, new metal let in and sealed.
Valley
$500 – $1,500
The most concentrated water on the roof. Shingles come back on both planes.
Complex or multiple leaks
Can exceed $2,500
Several causes, or one cause that has been wet long enough to take the decking with it.
Mould remediation, if it got that far
$500 – $5,000
Not a roofing cost. It is the cost of the months before you called.
National 2026 ranges from Veteran Roofing Systems' price guide. Lamar Homes repairs in the Triangle start at $625; the final price comes from the inspection, not from a table.
The short answer
You are not buying a repair, you are buying a diagnosis
Every one of those ranges assumes somebody already knows what is wrong. That is the whole trick of pricing a leak: the repair is often cheap and the finding is the skilled part. [A roofer who quotes your leak over the phone is quoting somebody else's roof and hoping it rhymes with yours.]
Our repairs start at $625 and the inspection that produces the number is free. We get on the roof, photograph what is actually there, and hand you one written price with the decking as its own line, because decking is the thing that turns a small repair into a real one.
Five things that change the price for the same leak
Same cause, same shingles, very different invoice.
Access and pitch
A walkable single story is a ladder and an hour. A steep third story is staging, harnesses and two people. The leak does not know the difference; the price does.
How long it has been wet
Decking that has been damp for a season is soft, and soft decking comes out. This is the single biggest jump between a $600 repair and a $2,000 one, and it is entirely a function of waiting.
How many causes there are
Two leaks in two places is two repairs. It is also a signal worth taking seriously on a roof over fifteen, because the third one is usually already forming.
Emergency versus scheduled
A tarp tonight and a repair on Thursday costs more than a repair on Thursday. Sometimes that is the right trade, and sometimes the rain has passed and it is not.
What the last person did
Roofing cement over failed flashing is cheap to apply and expensive to undo, because it has to come off before the real repair goes on. Old bad repairs are a real line on a real quote.
Insurance
When the leak is somebody else's bill
The line insurers draw is sudden and accidental against wear and neglect. A limb through the roof in a storm is covered. A twenty year old roof that finally gave up is not, no matter how sudden it felt to you.
Which means the evidence decides it. Dated photographs from the roof, a written report that describes the damage as storm damage rather than age, and a claim filed inside your policy's window. We do all three as part of the inspection, and we meet the adjuster on the roof with you. Our insurance claims page covers the process.
One honest caution: if the repair is near your deductible, claiming can cost more than paying. We give you the repair price before anyone files, so the choice is yours with a number in hand.
The cost of waiting
What a $300 leak turns into
The published guides put it bluntly, and so will we.
Plywood that stays damp loses strength and delaminates. Once it is soft it is a carpentry job before it is a roofing job, and the roofing still has to happen afterwards.
Mould
Published remediation runs $500 to $5,000, and none of it is roofing work. It is the price of the months between the first stain and the phone call.
The claim you can no longer make
Most policies have a window for reporting storm damage, and an insurer who sees months of staining will call it maintenance. Waiting can turn a covered claim into your problem.
What we do
One inspection, one written price
We get on the roof, find the actual entry point, photograph it, and hand you a written price with the repair, any decking and any old-repair removal as separate lines. It is free and there is no obligation, and if the roof has years left in it that is what the report will say.
Repairs start at $625. If the honest answer is that the roof is past repairing, we quote the replacement beside the repair so you can see both numbers rather than take our word for which one you need. Our roof replacement cost guide has those ranges.

Questions
Roof leak repair cost questions
How much does it cost to fix a roof leak?
Our repairs start at $625. Nationally, published 2026 ranges put a leak repair between $350 and $1,500, with a simple vent boot at the low end and a valley or chimney rebuild at the high end. The figure depends on the cause, the access and the decking.
How much does it cost to replace roof flashing?
Chimney flashing is published at $400 to $1,200 nationally, and valley work at $500 to $1,500. Both are more than a boot because both mean lifting shingles and doing metalwork rather than swapping a part.
Does homeowners insurance cover a roof leak?
Generally yes when a storm caused it and no when age or lack of maintenance did. Sudden and accidental damage is covered; a roof that wore out is not. Dated photographs and a written report are what decide it.
Is it worth claiming on insurance for a leak?
Not always. If the repair is close to your deductible, claiming costs you the excess and a claim on your record for very little. We tell you the repair price first so you can do that maths before anyone files anything.
Why is my leak repair more expensive than the quote next door?
Access and decking, usually. A single story walkable roof and a steep third story with the leak behind a chimney are different jobs with the same description. Anyone quoting a leak without getting on the roof is guessing.
