Roof Leak Detection in Jamesburg

Yes -- that is largely what this is for. You get a written finding naming the entry point and the component that failed, with photographs. It is deliberately specific about WHICH building component, because that is what somebody has to match against the governing documents.

Then the report says so. Some leaks only present under particular wind directions or after prolonged rain and cannot be reproduced on a dry Tuesday. A report that invents a conclusion to justify the visit is worse than one that records what was ruled out.

It is a Florida rule and it does not apply in New Jersey. The 25% rule comes from the Florida Building Code Existing Building, where repairing or replacing more than a quarter of a roof within a year can require the whole thing to be brought up to current code. New Jersey has no equivalent provision. It turns up in searches here because national content repeats it without saying which state it belongs to, and anyone quoting it at you in this state is citing the wrong code book.

In New Jersey the question is not the job title, it is the registration. Anyone doing home improvement work on a residence must be registered as a home improvement contractor, and the registration number has to appear on their advertising, their vehicle and any contract. Beyond the paperwork, the practical limit is diagnosis: sealing a visible hole is within most people's reach, and working out that water is entering at a chimney and surfacing two rooms away generally is not.

Most leak repairs in this market run $350 to $1,800, with genuinely minor work from about $150. The wide spread is because it covers two different jobs: putting right a failure you can see, and finding one you cannot. If a quote is at the top of that range, the thing to ask is what it includes by way of actually locating the entry point, because that is where the work is.
