It is the first question almost every homeowner asks, and it is a fair one. The trouble is that a roof is not a product off a shelf. Two houses on the same street can carry very different numbers, and the only honest way to price a roof is to look at it. Still, you deserve a straight explanation of what drives the cost and a realistic range before anyone shows up. So here it is, plainly.
What Actually Drives the Price
A few things do most of the work when it comes to the final number. The first is simply size. Roofers measure in squares, where one square covers one hundred square feet, so a bigger roof means more material and more labor. Pitch matters too. A steep roof is slower and more dangerous to work on, and that shows up in the price.
The next factor is how many old layers have to come off. A roof that already carries two layers of shingles takes longer to tear off and hauls away more debris than a single layer. Once that old roofing is gone, we get our first real look at the decking underneath. If the plywood is solid, great. If we find soft or rotted boards, those need to be replaced so the new roof has something sound to attach to.
The material you choose changes the number as well. A basic three tab shingle and a heavier architectural or designer line are not the same price, and they are not the same roof. Finally, the details add up. Chimneys, valleys, skylights, and proper ventilation all take extra flashing, time, and care to do right. A simple gable roof and a cut up roof with several of these features will not land in the same place.
The Rough Range
With all of that said, people still want a number to hold onto, so here is an honest one. On a typical single family home in the South Hills, an asphalt shingle replacement generally runs somewhere from around $10,000 to $20,000.
Please read that as a rough range and not a quote. Where your roof falls inside it, or whether it sits outside it, depends entirely on the factors above. A smaller, simple roof with one layer to remove sits toward the low end. A large, steep, multi layer roof with several skylights and bad decking sits toward the high end. The only way to know your number is to measure your roof.
How R&G Prices a Roof
Our process is straightforward. We come out, walk the roof, and actually inspect it. Then we hand you a written, itemized estimate, and that is free. You can see exactly what you are paying for, line by line, instead of a single lump sum with no explanation.
The number on that paper is the number you pay. When a roof is properly inspected before the work, there are no surprise change orders for things that should have been caught up front. We have been doing this in the South Hills since 1999, out of Castle Shannon, and that reputation is the whole business. We are an Owens Corning Preferred Contractor, which means qualifying systems can carry extended manufacturer warranty options, so the roof is protected long after we have packed up.
Sometimes a Repair Is the Right Call
Not every roof needs to be replaced. If you have a roof with plenty of life left and a localized problem, a repair is often the smarter and cheaper move. We will tell you that honestly. We would rather fix what can be fixed and keep you as a customer than sell you a roof you do not need yet. If it can wait, we will say so.
