Why Roof Trim Boards Matter
Before diving into pricing, it’s important to understand why exterior roof trim boards are essential.
1. Protection from the Elements
Roof trim helps seal the edges of your roofing system, keeping water, pests, and debris from entering the attic or damaging the siding.
2. Support for Gutters
Fascia boards, in particular, provide critical support for your gutter system. If the trim is damaged, your gutters could sag or detach entirely.
3. Improved Curb Appeal
Rotting or cracked trim boards are noticeable from the street and can significantly lower your home’s aesthetic value and resale price.
Common Types of Roof Trim Boards
The type of material used will greatly influence how much cost to replace exterior house roof trim boards. Here are the most common options:
1. Wood Trim Boards
- Pros: Natural look, customizable, paintable
- Cons: Susceptible to rot, pests, and weather damage
- Cost: $1.50 – $3.50 per linear foot (materials only)
2. PVC (Plastic) Trim Boards
- Pros: Weather-resistant, rot-proof, low maintenance
- Cons: More expensive than wood, limited color options
- Cost: $3.50 – $7.50 per linear foot
3. Fiber Cement
- Pros: Extremely durable, moisture and insect resistant
- Cons: Heavier, more labor-intensive to install
- Cost: $4.00 – $8.00 per linear foot
4. Aluminum or Metal-Wrapped Trim
- Pros: Low maintenance, water-resistant
- Cons: Prone to denting, may expand/contract
- Cost: $3.00 – $6.00 per linear foot
How Much Cost To Replace Exterior House Roof Trim Boards?
Now to the main question: What’s the actual cost?
Here’s a breakdown of average costs per linear foot, which is the standard way of measuring roof trim replacement.
| Category | Cost Range (Per Linear Foot) |
|---|---|
| Material Only (Wood) | $1.50 – $3.50 |
| Material Only (PVC) | $3.50 – $7.50 |
| Labor | $4.00 – $8.00 |
| Removal & Disposal | $0.50 – $2.00 |
| Total (All-In) | $6.00 – $16.00 |
Full Replacement Estimate Example:
If your house requires 200 linear feet of trim:
- Low-End: 200 x $6.00 = $1,200
- High-End: 200 x $16.00 = $3,200
Factors That Influence Replacement Cost
While the per-foot estimate gives a general idea, actual costs vary depending on several key factors:
1. Extent of Damage
Is the damage isolated to a small section, or does it extend around the entire house? Spot repairs are cheaper, but full replacement offers better long-term value.
2. Accessibility
If your home has a steep roof, multiple stories, or complex architecture, labor costs will rise due to the additional time and safety measures required.
3. Location
Labor and material costs vary by region. Urban areas often have higher labor rates than rural ones.
4. Type of Trim
Premium materials like fiber cement and PVC will increase costs but may require less maintenance and fewer replacements in the future.
5. Paint and Finishing
Some materials come pre-finished, while others require painting or sealing, adding to both labor and material expenses.
When Should You Replace Roof Trim Boards?
Replacing roof trim boards isn’t always urgent, but there are clear signs that it’s time to invest:
- Visible Rot or Cracks
- Peeling Paint or Warping
- Gutter Separation or Sagging
- Animal or Insect Infestation
- Water Stains on Soffits or Fascia
If you notice any of these signs, it’s a good idea to get a professional evaluation before the damage spreads to structural components like roof decking or rafters.
DIY vs Professional Replacement
DIY Option:
Homeowners with the right tools and skills might consider replacing the trim boards themselves to save on labor.
- Pros: Save 30–50% of the cost
- Cons: Safety risks, time-consuming, potential for mistakes
Estimated DIY Cost:
- Tools & Materials: ~$300–$800 for an average home
Professional Installation:
Hiring a contractor ensures the job is done safely and efficiently, especially for second-story homes or complex rooflines.
- Pros: Quality assurance, warranty, faster turnaround
- Cons: Higher cost
Cost-Saving Tips
Looking to reduce the cost of replacing exterior trim? Here are a few practical tips:
✔️ Get Multiple Quotes
Always get at least 3 estimates from licensed contractors to compare pricing, experience, and customer reviews.
✔️ Replace During Roofing Projects
If you’re already replacing your roof, adding trim replacement to the job may lower the cost due to shared labor and equipment.
✔️ Choose Mid-Range Materials
PVC trim offers durability with less maintenance than wood, and it’s often cheaper than fiber cement or metal.
✔️ Partial Repairs
If only part of your trim is damaged, targeted repairs may cost as little as $150–$500.
What’s Included in Trim Replacement Services?
When hiring a professional, a full trim replacement typically includes:
- Removal of old boards
- Disposal of materials
- Installation of new trim
- Caulking and sealing
- Painting or finishing (if not prefinished)
- Inspection for underlying damage
Hidden Costs to Watch Out For
Some additional costs may arise, depending on the condition of your existing structure:
1. Rotten Roof Decking
If trim boards are rotting, nearby decking or rafters may be damaged as well. Replacing this could cost an extra $300–$1,000+.
2. Gutter Reattachment
If your gutters are attached to the fascia, they’ll need to be removed and reinstalled. Some contractors charge extra for this.
3. Permits
In some cities, permits may be required for exterior work. These can add $50–$150 to your bill.
How to Maintain Roof Trim Boards
To extend the life of your new trim boards and avoid early replacement costs:
- Inspect Annually: Look for cracks, water damage, or peeling paint.
- Clean Gutters: Clogged gutters cause overflow that can damage fascia.
- Seal and Paint: Keep wood trim sealed and painted every 3–5 years.
- Address Leaks Promptly: Stop leaks before they cause wood rot.
Conclusion
So, how much cost to replace exterior house roof trim boards? It depends on several variables including the type of material, labor costs, house design, and regional pricing. On average, expect to spend $6 to $16 per linear foot, with a full home replacement ranging between $1,200 and $3,200 for most standard-sized homes.
Although it’s possible to save with a DIY approach, hiring a professional ensures lasting quality and avoids hidden complications. Whatever route you choose, maintaining your roof trim is essential for protecting your home, preserving curb appeal, and ensuring long-term value.
If your trim is showing signs of wear, don’t wait—address it early to prevent more expensive repairs down the road.
