To repair a roof or not, that is the question. Actually, the question is based on whether the cost is worth doing it now or waiting a while. In which case, it is more like a gamble. And a wager that each homeowner makes virtually every day. Yet, when an obvious problem comes up, such as water trickling overhead, into your living space, the decision is easy: fix the leak! Do nothing between now and the next time your roof needs to be replaced and the odds are against you. Sure, you might get lucky, but you have ample opportunity to make your own luck.
We Can Fix It
High end costs are $1,500 to $3,000 and are generally repairing material under the roof’s outer layer, possibly addressing damaged wood in other parts of the house, such as outer walls. Plus replacing all shingles on sections of the roof (think 10 by 10-foot areas).
Moderate repairs are likely fixing and/or sealing fixtures on the roof and replacing shingles and flashing around these objects.
Asphalt shingles cost roughly $500 to $1,000 to replace or repair 10 by 10 square feet section
Chimneys, vents, skylights and related fixtures on a roof are going to vary in price. In general, the cost would start around $450 and go up. Generally, shingles around the fixture need to be removed to repair sealing and fix flashing. Then shingles are replaced.
If there are multiple fixtures needing repair, yes, the cost will go up, but generally a contractor will reduce the rate for each as they are already up there, with all the tools.
With chimneys, the cost can quickly go to the $750 range or higher as the damage to the chimney structure may be determined a source of roof problems and that would need to be fixed first.
Damage to flashing in valleys means removing shingles around it, fixing the flashing or (more likely) replacing it, and then replacing the shingles, and sealing everything. This ranges from $200 to $600, and depends on how long the valley is, how steep the slope of the roof and how many shingles actually need to be replaced.
