Roof replacement in Fort Collins

When it's time

A Fort Collins roof replacement tends to come due in waves, because so many roofs were replaced after the same hailstorms. Whole streets in Fossil Creek, Miramont and the neighborhoods off Harmony Road were re-roofed within a year or two of each other, and those roofs are now hitting the 15–20 year mark in a climate that wears out a 30-year shingle in about 20. The signs:

• Granules an inch deep in the gutters and bare black patches on the south and west slopes
• Shingle edges curling or cupping, where hail and wind both get their grip
• Hail bruises — soft, dark spots the size of a fingertip — on more than one slope
• Two or more repairs in the last couple of years in different places
• A roof already on its second layer, visible at the drip edge
• Decking that feels spongy underfoot

Two of those and it's time for an inspection. Read the guide on signs a Fort Collins roof is near the end, then request an estimate. If the roof has three more years, a good roofer will say so.

What a full replacement should include

Residential roof replacement in Fort Collins, CO has three jobs the rest of the country mostly doesn't: take a hailstone without bruising, hold on in a chinook, and shed a foot of wet April snow without letting meltwater back up under the eaves. A full replacement should include:

Full tear-off to the deck. No roof-overs. A second layer hides rotten decking, adds weight, and can void the shingle warranty — check the manufacturer's terms.

Decking inspection and replacement. Every sheet should be walked. Soft or delaminated plywood typically runs $90–$150 per 4x8 sheet to replace — expect an allowance in the quote and photos of any sheet that gets swapped.

Synthetic underlayment across the whole deck. Felt wrinkles in the dry air here and tears in the wind before the shingles are on.

Ice-and-water membrane along the eaves, in every valley, and around every penetration. Whether a re-roof needs a permit, and what the code requires at the eaves, depends on the job — check with the City of Fort Collins building department (or your town's), and ask your roofer who pulls the permit.

Architectural shingles — or Class 4. Standard architectural shingles from GAF, Owens Corning, CertainTeed or Malarkey nailed with six nails per shingle, or a UL 2218 Class 4 impact-resistant line for $40–$90 more per square. Many Fort Collins homeowners choose Class 4, and the Class 4 page explains why.

New drip edge, pipe boots and flashing. A good roofer replaces old flashing rather than reusing it: step flashing at walls, new counter-flashing at chimneys, new boots on every vent.

Ventilation. Ridge vent cut in, soffit intake cleared or added. Poor roof ventilation (Fort Collins attics often have it) is why shingles cook from below in July and why ice dams form in March, and it's cheap to fix during a replacement.

Permit and inspection. Ask who pulls the permit and when the city inspection is scheduled before you sign.

Cleanup. Tarps over the landscaping, a trailer for the old roof, and a magnet sweep of the lawn and driveway for nails before the crew leaves.

Roof replacement options: architectural, Class 4 or metal

Standard architectural shingles are the baseline and the cheapest roof that suits this climate. Class 4 impact-resistant shingles add $40–$90 per square and usually ride out the hail that would total a standard roof. With metal roofing, Fort Collins homeowners usually mean standing seam, and it makes sense on a house you'll keep 15 years or more: it doesn't bruise, most panels carry a Class 4 rating, and it sheds snow. It costs two to three times what shingles do — $30,000–$50,000 on a typical 2,000 sq ft two-story. Ask for the shingle and metal prices side by side.

What it costs

Architectural shingle roof replacement in Fort Collins runs $450–$800 per square installed. A typical 2,000 sq ft two-story in Rigden Farm or English Ranch with 24–28 squares of roof is about $12,000–$20,000, and a simple 1,300 sq ft ranch off Drake Road is typically $9,500–$13,000. Steep pitches, a second layer to remove, lots of valleys and dormers, and decking replacement push toward the top. Roof installation in Fort Collins takes one to two days on most homes. The cost page breaks it down by house size, and the post on 2026 roof replacement costs explains what moves the number.

When hail did the damage, a claim may pay for the replacement minus your deductible — see hail damage and claims. When it's just age, it's a purchase; ask about financing options, and don't let anyone push you into one.

How a replacement day usually goes

1. Delivery. Shingles and underlayment arrive a day or two ahead, usually on the driveway or loaded straight onto the roof. Move cars, and anything fragile off the walls inside, because the hammering carries.
2. Tear-off. The old roof comes off one section at a time into a trailer or dumpster, down to the bare deck.
3. Deck check. Every sheet gets walked. This is when soft plywood shows up, and when you should get a call and a photo before the allowance is exceeded.
4. Dry-in. Membrane at the eaves and valleys, synthetic underlayment over the rest. Once this is down, a passing shower is not a problem.
5. Shingles, flashing and ridge. Starter course, field shingles, new boots and flashing, then the ridge vent and caps.
6. Final walk. Ask to walk the property with the crew lead: nails swept, gutters cleaned out, no shingle scraps in the beds.

Mistakes to avoid when you replace

• Choosing on the bottom number alone. The cheapest quote is usually the one missing a line — the membrane, the decking allowance or the permit.
• Skipping the ventilation. The deck is open; this is the cheapest moment you will ever have to fix a hot attic.
• Signing a contingency agreement before you've seen a written price. You can't compare anything once you've signed.
• Not asking about the gutters. Hail-dented gutters left on a new roof keep rotting the fascia. Price them separately, from a gutter contractor if needed.
• Paying most of it up front. A large deposit before materials arrive is a red flag; ask how the payments are staged.
