Cost to Reframe a Roof and Replace Trusses (2026 Guide)

For most homeowners, a roof replacement is a straightforward exterior project: tear off the old shingles, lay down some underlayment, and nail down the new shingles. However, if your roof has suffered catastrophic damage from a massive fallen tree, severe water rot from decades of neglect, or a massive winter snow collapse, simply replacing the shingles is no longer an option. You must rebuild the actual skeleton of the house. Understanding the true cost to reframe roof structures is vital when planning a massive structural renovation or recovering from a disaster. In this highly technical framing guide, we will break down exactly how much it costs to replace roof trusses, analyze the replacing roof rafters cost, and explain how contractors price building a roof entirely from scratch.

The average cost to reframe roof structures ranges from $15,000 to $30,000 for a standard residential home. If you are entirely rebuilding the structure, the cost to build a roof from scratch typically ranges between $15 and $30 per square foot for the wooden framing and labor alone (excluding the final shingles).

How Much Does It Cost to Reframe a Roof?

If your home’s roof has a visibly severe sag in the center, or if the ridge line looks like a roller coaster rather than a perfectly straight line, you have a massive structural failure on your hands. The wooden framing inside your attic is actively collapsing.

When you ask a general contractor how much does it cost to reframe a roof, the estimate will be broken down into three distinct phases:

1. Demolition ($2,000 - $5,000): The crew must completely tear off the exterior shingles, rip off the plywood decking, and carefully dismantle the rotting wooden framing without damaging the ceiling drywall inside your home.
2. Structural Framing ($10,000 - $20,000): Expert carpenters will install the brand new wooden trusses or custom-cut rafters to form the new skeleton of the roof.
3. Plywood Sheathing ($3,000 - $5,000): Once the framing is up, the crew must nail down massive sheets of OSB or plywood to create the flat deck that the shingles will eventually attach to.

For a standard 2,000-square-foot home, the baseline cost to reframe roof structures will reliably land around $20,000 for the lumber and carpentry labor alone. Note: You will still have to pay an additional $8,000 to $12,000 to a roofing contractor to actually install the shingles on top of your new frame.

What Is the Cost to Replace Roof Trusses?

When building modern homes, contractors do not cut the roof framing by hand. Instead, they use pre-fabricated “trusses.” Trusses are highly engineered, triangular wooden webs that are built in a factory, shipped to your house on a flatbed truck, and lifted onto your walls with a massive crane.

If your home has suffered severe fire damage or a tree collapse, the cost to replace roof trusses is highly dependent on logistics. A single prefabricated wooden truss typically costs between $75 and $250. A standard home requires a truss placed every 24 inches, meaning you will need roughly 30 to 40 trusses (totaling $3,000 to $8,000 in raw materials).

However, the real expense is the crane rental and the specialized carpentry labor required to set them perfectly plumb and level. You should expect the total installed cost to replace roof trusses to hover around $12,000 to $18,000 for a medium-sized home.

What Is the Replacing Roof Rafters Cost?

If you live in a historic home built before the 1960s, your roof was likely “stick-framed” using traditional rafters instead of factory-built trusses. Rafters are long, thick pieces of lumber (usually 2x8s or 2x10s) that are cut by hand on the job site and nailed to a central ridge board.

If a severe roof leak has rotted out a section of your historic roof, the replacing roof rafters cost will be calculated purely by the hourly rate of a master carpenter. Because stick-framing requires complex geometry, precise manual cuts, and slow installation, the labor is significantly more expensive than simply dropping factory trusses with a crane.

To replace a small section of rotted rafters (perhaps a 10-foot section), a carpenter will typically charge $2,000 to $4,000. If you need to stick-frame an entire 2,000-square-foot roof from scratch, the highly specialized labor will easily push the replacing roof rafters cost past $25,000.

The Hidden Cost to Build a Roof (Permits and Engineering)

You cannot simply hire a carpenter to start ripping off your roof and cutting new wood. Modifying the structural framing of a house is the most heavily regulated aspect of residential construction.

Before any framing begins, you face two massive hidden costs:

1. Structural Engineering ($1,000 - $3,000): You must hire a licensed structural engineer to draw up official blueprints for the new roof. The engineer will calculate the exact “snow load” and “wind load” the new roof must withstand, dictating exactly what size lumber the carpenters must use.
2. Municipal Permits ($500 - $1,500): You must submit those stamped engineering blueprints to your local city building department to secure a structural permit. During the framing process, a city inspector will visit your house multiple times to verify that every single hurricane tie and nail meets the strict building code.

Conclusion

Understanding the true cost to reframe roof structures prepares you for one of the most expensive and invasive renovations in home ownership. By expecting to pay between $15,000 and $30,000 for the structural framing alone, you can properly negotiate with your insurance company following a catastrophic tree collapse or fire. Whether you are paying the high labor premium of the replacing roof rafters cost for a historic home or utilizing a crane for the cost to replace roof trusses on a modern house, always prioritize hiring a licensed, bonded, and insured structural framing crew.

Once your new framing is complete, you will need to budget for the actual exterior shingles. Try our Free Roofing Calculator today to get an instant, accurate estimate for the final finishing touches on your brand new roof.

FAQ

Can I change the pitch of my roof during a reframe?

Yes. If you are already paying the massive cost to tear off the entire roof and build a new skeleton from scratch, this is the perfect time to completely change the architectural look of your home. You can ask your structural engineer to design a much steeper pitch to shed snow faster, or add massive dormer windows to create livable attic space.

Will my homeowners insurance cover the cost to reframe a roof?

If the structural damage was caused by a sudden, catastrophic “act of God” (such as a massive oak tree falling on your house during a storm, or a lightning fire), your homeowners insurance policy will generally cover the entire cost to rebuild the roof framing. However, if the framing simply rotted away over 20 years due to a slow leak you ignored, the insurance company will deny the claim citing “lack of maintenance.”

Can I live in my house while the roof is being reframed?

No. During a structural roof reframe, the entire top of your house is completely exposed to the elements. The demolition process creates massive amounts of toxic dust, falling debris, and intense vibrations that will crack the drywall below. You must completely vacate the premises and secure temporary housing for the 2 to 4 weeks it takes to reframe and weatherproof the house.
