Flat Roof Leak Repair in Jamesburg

Not in itself. Water that clears within a day or two of rain is normal. Water still there a week later is a seam being tested continuously, and it usually means the fall does not actually run or an outlet is not at the low point.

It depends who built it. Where a low-slope addition was put on by the original builder it is usually treated as part of the structure; where a previous owner added it, it frequently is not, and may not appear in the reserve study at all. That is worth establishing before it fails rather than after.

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.
