A new roof is one of the bigger projects most homeowners take on, and the first question is almost always the same: how much will it cost? The honest answer is that it depends on your roof. Two houses on the same street in Duluth can have very different prices because of the size, the pitch, what is under the old shingles and the materials you choose.
This guide explains what drives the price of a roof replacement here, how to compare quotes fairly, and how to plan the timing so your project goes smoothly.
How roofs are measured and priced
Roofers measure roofs in squares. One square is 100 square feet of roof surface. A typical Duluth house might have anywhere from 15 to 35 squares, depending on the footprint, the pitch and how many sections the roof has. Steep roofs have more surface area than flat ones over the same footprint, so a steep house on the hill can have far more roof than a ranch house with the same floor plan.
The quote is built from the materials for those squares, the labor to remove the old roof and install the new one, and the extras that every roof has: flashing, vents, drip edge, ice and water shield, disposal and permits.
What drives the price up or down
Size and pitch
More squares mean more materials and more labor. Steep roofs also take longer and need extra safety equipment, so the price per square rises with the pitch.
Complexity
Valleys, dormers, skylights, chimneys and several roof levels all add flashing work and cutting. A simple gable roof costs less per square than a roof with many facets.
Layers to remove
Many older Duluth homes have two layers of shingles, and some have more. Each layer adds removal time and disposal weight. We tear off down to the deck on every replacement, so we can check the sheathing and install the underlayment properly.
Deck repairs
Once the old roof is off, soft or rotted sheathing has to be replaced. On older homes we sometimes find board decking with wide gaps that needs new plywood over it. Your quote should say how deck repairs are priced, usually by the sheet, so there are no surprises.
Materials
Standard architectural shingles are the most common choice. Impact-resistant shingles cost more but hold up better to hail. Metal roofing costs more up front but can last 40 years or more and sheds snow well. Your choice of material is often the biggest single factor in the price.
Ventilation and ice protection
In Duluth, ice and water shield at the eaves and in the valleys is a must, and balanced attic ventilation helps prevent ice dams. If your attic needs new soffit or ridge vents, that adds to the cost but pays off in a longer-lasting roof.
Gutters and extras
Many homeowners replace gutters, skylights or chimney flashing at the same time as the roof, since everything is already exposed. These are usually listed as separate line items.
How to compare quotes fairly
The lowest number is not always the best value. When you compare quotes, check that each one includes the same things:
- Full tear-off to the deck, and how many layers are being removed
- How deck repairs are priced if rotted sheathing is found
- Ice and water shield at the eaves and in the valleys, and how far up the roof it goes
- Type of underlayment over the rest of the roof
- New drip edge, step flashing and chimney flashing, not reused old metal
- Ventilation changes, if any
- Shingle brand and line, and the manufacturer warranty
- The roofer’s own workmanship warranty, in writing
- Permit, disposal and clean-up, including a magnet sweep for nails
Also confirm that the roofer holds a Minnesota residential roofer license and carries insurance. A quote that leaves out flashing or ice and water shield may look cheaper but cost more when the roof fails early.
Timing your roof replacement
Shingles need warm temperatures to seal properly, so most roof replacements in Duluth happen from May to October. Spring and early summer fill up quickly with storm work and roofs that leaked over the winter, so booking an estimate early gives you the most choice of dates.
If your roof is leaking now but the season is over, a roof repair can often hold things together until spring. We will tell you honestly whether a repair makes sense or whether it is time to plan for a new roof.
Signs it is time to budget for a new roof
- The roof is 20 or more years old
- Shingles are curling, cracking or missing in several places
- Granules collect in the gutters after every rain
- You get ice dams and leaks every winter
- Several areas have been repaired and new leaks keep appearing
Getting an accurate price for your roof
The only way to know what your roof will cost is to have it measured and inspected. Our estimates include a look at the roof and the attic, photos of what we find and a written quote that lists materials, warranty and every line item. There is no pressure to book, and you can use the quote to compare with others.
