7 Signs Your Roof Needs Replacing

Both are good products. They fail in different ways, cost different amounts, and suit different houses. Here is the comparison without the manufacturer marketing.

Vinyl gets more brittle as it gets colder. At Buffalo's January temperatures, a decent impact — a snowblower throwing a chunk of ice, a ladder set down carelessly, a stone off a mower in the shoulder season — can crack a panel where in July it would have flexed. This is the most common real-world vinyl failure we see.
Fiber cement is not brittle in the same way. It is a cementitious board, and cold does not change its behaviour much. It can chip at the edges if handled badly, but it does not crack from a cold-weather knock.
Vinyl moves a lot with temperature — a long panel can change length noticeably between a January night and a July afternoon. That is why vinyl is designed to hang loosely, with nails driven to leave a little play and gaps left at the ends. Install it nailed tight and it buckles and waves in the summer heat. This is the single most common vinyl installation mistake, and once it waves, it stays waved.
Fiber cement barely moves. It gets fastened firmly and stays where you put it, which is part of why it holds a crisp line on a long wall.
Neither is the actual water barrier — the house wrap behind it is. But fiber cement is more forgiving of persistent damp, which matters on north walls, under deep eaves, and near grade. Its known vulnerability is wicking moisture at cut ends and at horizontal surfaces, which is why proper installation leaves a gap where the board meets a roof or a deck, and why field cuts get sealed. Done right it is excellent here. Done badly, the bottom course starts to soften after several winters.
Installed costs vary with the house, the amount of trim and detail work, and whether there is old siding to remove. As a working range for Western New York:
On a typical WNY two-storey that difference is not trivial — it is often the deciding factor, and there is nothing wrong with that. Vinyl on a house that needs siding now beats fiber cement on a house that keeps waiting.
These are Western New York market ranges, not a TNE quote. Our estimates are free and specific to your house.
Good vinyl, properly installed, will give you 25 to 40 years. It never needs painting. It does need washing — north-facing walls in shaded neighbourhoods pick up green algae, and a low-pressure wash once a year or two keeps it looking right. Faded vinyl cannot be restored; badly faded panels get replaced, and matching a discontinued colour is a genuine problem.
Fiber cement will go 40 to 50 years or more. Prefinished factory coatings typically carry long finish warranties; site-painted fiber cement will want repainting somewhere around 10 to 15 years, which is a real future cost to factor in. Caulk joints need checking every few years.
Installation quality matters more than the product choice. We have seen fifteen-year-old vinyl that looks great and three-year-old fiber cement that is failing at the bottom course because nobody left a gap above the deck. Whichever you pick, the things that decide how it ages are the house wrap, the flashing at windows and doors, the fastening pattern, the clearance at grade and horizontal surfaces, and the trim details.
Those are also the things that are invisible once the job is done, which is exactly why they get skipped by whoever gave you the cheapest number.

The ones we get asked most often.
Sometimes, but we usually recommend against it. Removing the old siding lets us see and fix the sheathing, install proper house wrap, and flash the windows correctly. Going over the top hides problems rather than solving them.
A little, and less than the marketing suggests. Insulated vinyl adds a modest R-value. The bigger energy win in most WNY homes is air sealing and attic insulation, not the walls. We will not tell you siding will transform your gas bill.
Sometimes. Colours get discontinued and existing siding fades, so an exact match on an older house is often not possible. We will be straight with you about how noticeable it will be before you commit.
Yes — and doing them at the same time as the siding is both cheaper and how you get the detailing to look right.
