What does a new roof structure cost?
Short answer. Replacing the roof structure, meaning the rafters or trusses rather than just the shingles, is a framing project that costs many times more than a standard reroof, because it involves engineering, permits, temporary weather protection, new framing, new decking and a complete new roof. Most homes never need it; it comes up after a fire, a tree strike, long-term rot, or a remodel such as adding a second story.
When the structure is the problem
- A tree or large limb has cracked rafters or trusses.
- Fire has charred framing.
- Years of leaks have rotted rafters, especially at the eaves or around chimneys.
- The ridge sags noticeably or rafters bow between supports.
- A remodel changes the roof shape, adds a story or removes load-bearing walls.
Repair vs full replacement
Many structural problems are fixed locally: sistering new lumber alongside damaged rafters, replacing a few trusses with engineered repairs, or adding supports. Full replacement is reserved for widespread damage or a redesign.
What drives the cost
- Engineering and permit fees; structural work requires inspections everywhere in Georgia.
- The size of the area being reframed and lumber prices.
- Engineered trusses versus site-built rafters.
- Temporary protection of the house while it is open.
- New decking, underlayment and roofing on top.
- Interior ceiling repairs, insulation and electrical work.
Insurance
Sudden damage from a falling tree, fire or wind may be covered under your dwelling coverage, depending on the policy. Rot from long-term leaks generally is not.
Who does it
Structural framing typically involves a licensed residential or general contractor and often an engineer. See roofing permits in Georgia, signs you need a new roof and OSB vs plywood roof decking.
