Flat Roof Replacement in Mayfield Heights

EPDM at $5 to $9 a square foot and TPO at $6 to $12, and on normal residential additions either will do the job if the detailing is right. What matters far more here is the upstand height and the drainage, because both have to work with snow sitting on the roof rather than rain running off it.

Not in itself -- water that clears within a day or two is normal. Water still there a week later is a seam being tested continuously. In winter it is worse than that, because ice over an outlet means the roof has no drainage at all until it thaws.

Middle-aged rather than old. Twenty years is well inside the normal service life of architectural asphalt and at the end of it for three-tab, so the first useful question is which one you have. After that it is condition, not the date: granule loss, brittleness, how flat the covering lies, whether the deck is sound. In this climate add one more -- whether it has been damming, because a roof with twenty winters of meltwater under its bottom courses is older at the eaves than it is anywhere else.

On Greater Cleveland rates a 1,500 square foot roof works out at roughly $5,250 to $12,000 depending on product and complexity, and most land nearer $10,000 once tear-off, ice barrier and a permit are included. One frequent source of confusion: 1,500 square feet of FLOOR is not 1,500 square feet of roof. Pitch, overhangs and dormers commonly make the roof area a third larger, which is why quotes can look inexplicably far apart.

It is a Florida rule and it has no force in Ohio. 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 roof to be brought up to current code. Ohio has no equivalent provision. It shows up in searches here because national content repeats it without saying which state it belongs to -- and anyone quoting it at you in Ohio is citing the wrong code book.
