Asphalt Roofing in Laconia
Belknap County · Typical roofs: Mill-era gables, post-war ranch hips, converted-cottage add-ons · Exposure: City ground, moderate exposure; plough and shovel piles at the eaves
Complexity is what decides where a metal roof lands inside its published band. That is stated plainly on our cost page and it is the single most useful thing to understand before comparing two quotes. What gets said less often is that complexity does not load the two materials equally.
Shingle absorbs awkward geometry cheaply. A valley is cut shingle over membrane; a hip is a capped course; a dormer cheek is flashed with step flashing that comes out of a box. The same details in standing seam are fabricated — a valley pan with hemmed edges, a custom flashing at every penetration, panels cut to a rake that is no longer parallel to anything. The extra labour a complicated roof creates lands almost entirely on one of the two materials.
So the honest arithmetic on the converted cottages around the Weirs and Paugus Bay is not $8 against $16. Forty years of additions on those buildings produce valleys nobody drew, changes of pitch where a later ell dies into the original roof, and dormers added one at a time. A roof like that pushes a metal number toward the top of $12–$20 while moving an asphalt number far less inside $6–$10. The ratio opens up, and it opens up exactly where the roofs are hardest.
The reverse is true across the post-war ranch belt, where clean shapes keep metal near the bottom of its band and the two materials are closest together. Same city, same climate, opposite answer.
BasisInstalled bands of $6–$10 for asphalt and $12–$20 for standing seam, and the statement that position inside the metal band is mostly decided by complexity, are on the sourced cost page.
Laconia Note
In Laconia, have the asphalt and the metal quote measured off the same roof, then ask each of them how the valleys are detailed. On a cut-up conversion the valleys are where the cost difference lives and where the eventual leak turns up.
If It Is Asphalt, Spend the Money in the Right Places
First, the reason most people here price metal at all. It is ice dams, and metal will not fix them. It helps, genuinely: a metal plane sheds snow, and snow that has gone cannot melt into a dam. But the dam is caused by heat escaping into the roof assembly, melting snow from underneath, and that meltwater refreezing at a cold eave — and no covering changes that sequence. On a converted cottage the difference between the asphalt number and the metal number buys a great deal of air sealing and ventilation, which is the thing that actually stops it. Air sealing and ventilation first, roofing second, in that order, every time.
Then the valleys, because that is where a cut-up roof fails. On the long valleys of a conversion we specify an open metal valley rather than weaving the shingle through it. Water moves off a metal channel faster than it does across a shingle lap, and the pine and oak litter that collects on these lots washes through instead of damming in the weave. It costs a little more per valley. It is also where the leak turns up in year fifteen.
Then the deck, before anyone commits to a price. A cottage that has been added onto repeatedly has a patchwork underneath: board sheathing in the original, plywood or OSB in the later work, and frequently an old covering left in place where a plane was roofed over rather than stripped. Agree the deck repair rate in advance, per sheet and per board, so that what is found on the second morning is a known price rather than a negotiation.
And on a city lot, the tear-off is its own job. Where the container stands, whether it needs the street, and what disposal costs should be their own lines. Our fifty-year comparison works tear-off and disposal at $1.25 per square foot on every asphalt replacement, which is a reasonable place to start reading a quote from.
BasisThe $1.25 per square foot tear-off and disposal allowance is the figure used in the fifty-year comparison on the cost page. The ice-dam mechanism is set out in full in the ice dam guide.
Asphalt in Laconia runs the published $6–$10 per square foot installed — about $9,600–$16,000 on a 1,600 sq ft roof, against $19,200–$32,000 for standing seam. Service life is 18–25 years, up to 30 on premium architectural that is properly ventilated. Tear-off and disposal belong on their own line. Apply every one of those rates to your measured roof area rather than your footprint, which on the steeper village stock is roughly 1.45 times the floor plan.
- Both quotes measured off the same roof, so the difference between them is real
- Open metal valleys specified on a conversion roof rather than woven shingle
- Deck repair priced per sheet and per board before tear-off begins
- Ventilation corrected while the deck is open, not left as found
- Air sealing costed alongside the roof where ice dams are the reason you called
- Tear-off, disposal and where the container stands quoted as separate lines

Roofing Questions in Laconia
Is asphalt ever the right answer in Laconia?
On a heavily cut-up conversion roof it is the right answer more often than on any other stock in the city, and we would rather say so than sell you the larger job. Complexity loads a metal quote much harder than it loads an asphalt one, because every awkward junction becomes a fabricated detail rather than a cut shingle. The wider that gap gets, the harder metal has to work to justify itself.
We are pricing metal because of our ice dams. Will it fix them?
No. It will help — a metal roof sheds its snow, and snow that has left the roof cannot melt into a dam — but it does not fix the cause. Ice dams come from heat escaping into the roof assembly, melting snow from underneath, and that water refreezing where it reaches a cold eave. The covering has no part in that sequence. If dams are why you called, put the money into air sealing and ventilation first and choose the roofing afterwards.
Why is our metal quote more than double the asphalt one?
Almost certainly because of the shape of the roof rather than anything to do with the quote. The published bands are $6–$10 and $12–$20, which look like a clean doubling until you put a complicated roof through them. Valleys, changes of pitch and added dormers push the metal figure toward the top of its band while barely moving the asphalt one. Ask both roofers to show you the roof area and the number of valleys they priced, and the gap usually explains itself.
How long will an asphalt roof actually last here?
Eighteen to twenty-five years, and up to thirty for premium architectural shingle over a roof that is properly ventilated. What ends it in New Hampshire is freeze-thaw cycling cracking the binder and loosening the granules, which is why national lifespan figures read a few years generous for this climate. Ventilation is the one variable you control, and it is the reason we would rather correct it during the re-roof than after it.
