Repair or Replace Your Siding in 2026? Rot, Hail Damage and Costs
Last reviewed October 10, 2026
Quick answer
Repair siding when damage is limited to a few boards or one wall and matching material is available. Replace it if rot, warping, or hail damage covers multiple walls, water is getting behind it, or matching boards cannot be found. Repairs usually run $300 to $1,500; full replacement on a typical home runs about $10,000 to $25,000 depending on material.

Signs repair may be enough
- Damage is limited to a few boards or one wall
- Matching siding is still available
- The wall behind the damage is dry and solid
- Damage is cosmetic, such as small dents or faded paint
Signs replacement is necessary
- Rot or soft spots appear on several walls
- Hail damage covers multiple sides of the house
- Boards are warped, buckled, or loose across large areas
- Peeling paint or stains inside the home near exterior walls
- Matching material is discontinued
When waiting makes it worse
- Water behind siding can rot sheathing and framing
- Moisture can lead to mold inside walls
- Gaps let insects and pests into the home
- Insurance may deny long-neglected storm damage
Safety concerns
- Use ladders safely and avoid working near power lines
- Older homes may have asbestos or lead paint in siding
- Do not pressure wash directly upward into siding seams
Expected remaining lifespan
Vinyl siding typically lasts 20 to 40 years, fiber cement 30 to 50, and wood 20 to 40 with regular painting. Hail and sun exposure shorten lifespan.
DIY versus professional
Homeowners can caulk gaps, repaint wood siding, and replace a single vinyl panel. Multiple-wall repairs, rot repair, and full replacement belong with a licensed, insured siding contractor.
Questions to ask a contractor
- Are you licensed and insured?
- Will you replace water-damaged sheathing, and at what price?
- What house wrap and flashing are included?
- Can you match my existing siding for repairs?
