Exterior Renovation Case Study in Mount Prospect, IL: Roof Replacement & James Hardie® Siding Upgrade
In Mount Prospect, Illinois, this 1970s home underwent a complete exterior transformation designed to improve both structural integrity and curb appeal. The homeowner initially reached out after noticing active work happening in the neighborhood; an important reminder of how visible craftsmanship can inspire confidence and new projects.
Project Overview & Initial Challenges
This home presented several underlying issues that went beyond surface-level aesthetics. The existing roof structure was unsafe to walk on due to 24” on-center framing paired with thin, deteriorating plywood. There were also concerns surrounding moisture intrusion and potential mold caused by ice damming, which is common in older Midwest homes.
Additionally, the existing vinyl siding no longer reflected the homeowner’s pride in the property. After years of ownership and investment, the exterior lacked the durability and elevated appearance they were looking for.
Scope of Work & Exterior Upgrades
To address both structural concerns and visual impact, the project included a full roofing system upgrade and a premium siding installation.
Our roof replacement and ventilation improvements included:
- A full replacement of compromised roof decking
- Installation of a proper baffle system to improve attic airflow
- New GAF Timberline HDZ shingles in Charcoal for long-term performance and a modern look
These updates not only resolved safety concerns but also corrected ventilation issues that can lead to moisture buildup and long-term damage.
We provided a James Hardie® siding installation with custom accents, such as:
- Cedarmill lap siding combined with shake accents in Deep Ocean
- Arctic White trim for sharp contrast and clean lines
- ½” insulation board for enhanced energy efficiency and sound control
The combination of lap and shake siding created visual dimension, while the bold color selection elevated the home’s overall presence in the neighborhood.
Additional exterior enhancements included:
- Aluminum soffit and fascia in white
- New gutter system with integrated gutter guards
- Custom trim details to highlight architectural features
Together, these elements created a cohesive and polished exterior designed to last for decades.
Before, During, and After Transformation
The before condition showed clear signs of aging materials and outdated design. During construction, structural improvements (particularly roof decking replacement) highlighted the importance of addressing what lies beneath the surface. The final result is a dramatically improved exterior that feels both modern and durable, while still fitting seamlessly into the Mount Prospect neighborhood.
Here are details about the project size and timeline:
- Duration: 9 working days
- Roof Size: 2,900 sq ft
- Siding Coverage: 1,300 sq ft
Efficient project management ensured minimal disruption while maintaining high-quality installation standards.
Cost Breakdown for Mount Prospect Homeowners
For homeowners in Mount Prospect and surrounding areas considering a similar exterior renovation, here’s a realistic cost range based on this project:
- Roof Replacement (with partial deck replacement & ventilation fixes):
$21,000 – $25,000 - James Hardie® Siding Installation (including shake accents, insulation, and trim upgrades):
$23,000 – $30,000
These ranges reflect mid-to-large size homes with structural considerations and premium material selections.
Why This Project Stands Out
This project is a strong example of how addressing both structural integrity and design can significantly increase a home’s value. Rather than simply replacing materials, the approach focused on:
- Long-term durability (engineered siding and roofing system)
- Energy efficiency improvements
- Elevated curb appeal through thoughtful design choices
The addition of insulation and ventilation corrections ensures that the home performs as well as it looks, which is something especially important in Illinois’ fluctuating climate.
