Flat Roofing in Alexandria Township

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 run where somebody said it did.

Because it has probably been terminated with sealant rather than properly formed and fixed. On old masonry there is often nowhere obvious to tuck an upstand into, so somebody reaches for a tube. Sealant is a finish, not a fixing, and it is the commonest failure on this kind of roof out here.

It depends far more on the material than on the state, and out here the materials are not all asphalt. Architectural asphalt typically gives 20 to 30 years and three-tab 15 to 20. Standing seam metal commonly gives 50 and more. Exposed-fastener panel gives a long life too, but its screws and washers are consumables and want re-tightening -- a panel roof nobody has touched in 25 years is on borrowed time at its fixings rather than in its sheets. Natural slate outlasts all of them, frequently by a century, which is why so much of it around here needs nails rather than stone.

For a standard house, $12,000 to $18,000 covers most 2,000 square foot properties, within a full range of $9,500 to $26,000. The more useful answer for this area is that you cannot price an old building from a published range at all, because the number turns on things nobody can see from the road: what is under the covering, how many layers, whether the deck is boards, and whether the frame was built for the weight of what is on it.

In architectural asphalt, roughly $6,600 to $9,600 on New Jersey rates. But watch the units: 1,200 square feet of FLOOR is not 1,200 square feet of roof. Pitch, overhangs and dormers commonly make the roof area a third larger, and on a steep old farmhouse the difference is bigger still. That single confusion explains most quotes that look inexplicably far apart.
