Evaluating Your Existing Facade
Before selecting new siding or cladding, a thorough evaluation of the existing facade is essential. This involves more than just a visual inspection. You need to understand the current wall assembly, including its structural components, insulation, weather resistive barrier (WRB), and drainage plane. For many older Buffalo homes, the existing wall might be a simple sheathing and siding combination, while newer structures could have more complex rainscreen systems.
Key questions to answer include: What is the current condition of the sheathing? Are there signs of moisture intrusion, rot, or pest damage? Is the existing insulation adequate, or will this renovation be an opportunity to upgrade? A professional inspection, potentially involving opening up sections of the wall, can reveal hidden issues that must be addressed before new cladding is installed.
Material Selection: Balancing Aesthetics and Performance
The Buffalo climate presents unique challenges, with cold winters, snow, and freeze-thaw cycles. Your choice of siding and cladding should not only complement your desired aesthetic but also stand up to these conditions. Lumber Plus offers a range of materials suitable for exterior applications, each with distinct characteristics.
Thermally modified wood, such as Ayous or Ash, offers enhanced stability and resistance to decay, making it a robust option. Maximo Accoya is acetylated wood known for its exceptional durability and dimensional stability. For a different aesthetic and potentially lower maintenance, Norx composite cladding provides a consistent look and often requires less upkeep over time. Brazilian hardwoods like Ipe, Cumaru, and Garapa offer natural beauty and inherent strength. Consider how each material's properties align with your project's performance requirements and maintenance expectations.

Understanding Wall Assembly and Rainscreen Principles
A facade renovation is an opportune moment to improve the overall wall performance. Many modern cladding systems, especially in climates like Buffalo, benefit from a rainscreen assembly. A rainscreen creates a ventilated air gap between the exterior cladding and the weather resistive barrier, allowing moisture to drain and walls to dry.
Proper detailing of the rainscreen, including flashing around windows and doors, weep holes, and insect screens, is crucial for its effectiveness. If your existing wall does not have a rainscreen, incorporating one during the renovation can significantly enhance the durability and longevity of your new siding and cladding, preventing moisture-related issues that can lead to costly repairs down the line.
Installation Considerations and Substructure Compatibility
The installation method for your chosen siding or cladding will depend on the material and the existing wall structure. For wood and composite options, a robust substructure of furring strips or battens is typically required to create the necessary air gap for a rainscreen and to provide a secure fastening surface. Ensure that your existing sheathing can adequately support this substructure and the new cladding.
Fastening choices are also critical. Stainless steel fasteners are often recommended for exterior applications to prevent corrosion and staining, especially with certain wood species. Always refer to manufacturer guidelines for specific installation instructions, fastener types, and spacing requirements to ensure the long-term performance of your facade.
Worked Example: Renovating a 20-foot by 10-foot Wall Section
Imagine you are renovating a single wall section of a Buffalo home, measuring 20 feet wide by 10 feet high, totaling 200 square feet. The existing wall is traditional wood siding over plywood sheathing, showing signs of wear and minor rot near the base. You decide to replace it with 1x6 (nominal) thermally modified Ayous cladding, installed horizontally with a rainscreen system.
First, after removing the old siding, you discover some deteriorated plywood. This will need to be replaced. Next, a new weather resistive barrier will be applied. Then, vertical furring strips, typically 3/4-inch thick, will be installed over the WRB, spaced to accommodate the cladding and local building practices. For horizontal cladding, these furring strips provide the drainage plane and a secure nailing surface.
The 1x6 Ayous cladding boards have an actual face width of approximately 5.5 inches. To cover 10 feet (120 inches) vertically, you would need approximately 120 inches / 5.5 inches = 21.8 boards. Rounding up, you would plan for 22 courses of boards. For the 20-foot (240-inch) width, if using random lengths, you would aim to stagger joints over the furring strips. If using 10-foot lengths, you would need two 10-foot boards per course, totaling 44 boards (22 courses x 2 boards/course) for a basic estimate, plus an allowance for cuts and waste, often 10-15%. This planning ensures full coverage and accounts for the specific dimensions and installation method.
Before you order
- Have you assessed the existing wall assembly (sheathing, WRB, insulation)?
- Are there any signs of rot, moisture damage, or pest infestation that need remediation?
- Is the existing substructure adequate for the new cladding, or will it require upgrades?
- What are the local building code requirements for exterior cladding and rainscreen assemblies?
- Have you chosen a cladding material suitable for Buffalo's climate (e.g., thermally modified wood, Maximo Accoya, Norx composite)?
- Is the chosen material compatible with your desired aesthetic and maintenance expectations?
- Will you incorporate a rainscreen system, and have you planned for proper ventilation and drainage?
- Have you considered the fastening system and its compatibility with the chosen cladding and substructure?
- Have you accounted for waste and cuts in your material quantity estimate?
- Do you have a plan for flashing around windows, doors, and other penetrations?
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.

Questions to help you decide
What is a rainscreen system and why is it important for facade renovations?
A rainscreen system is an exterior wall assembly that includes an air gap between the outer cladding and the inner weather resistive barrier. This gap allows for drainage of any water that penetrates the cladding and promotes ventilation, helping the wall dry out. For facade renovations, especially in climates with significant rainfall and freeze-thaw cycles like Buffalo, a rainscreen is important because it enhances moisture management, reduces the risk of rot and mold, and can improve the overall durability and longevity of the wall assembly.
How do I choose between wood and composite cladding for a renovation?
The choice between wood and composite cladding depends on your priorities. Wood cladding, such as thermally modified wood or Brazilian hardwoods, offers a natural aesthetic, can be stained or left to weather, and is generally repairable. However, it typically requires more maintenance. Composite cladding, like Norx, often provides a consistent appearance, can be lower maintenance, and offers good durability. Consider your budget, desired aesthetic, maintenance commitment, and the specific performance characteristics required for your Buffalo project when making your decision.
What should I look for when inspecting my existing wall before cladding removal?
When inspecting your existing wall before cladding removal, look for signs of moisture damage such as staining, discoloration, or softness in the sheathing. Check for pest activity like insect tunnels or nests. Evaluate the condition of existing flashing around windows, doors, and rooflines. Also, assess the structural integrity of the studs and any framing, looking for rot or decay. Document any issues with photos and consider consulting a professional if significant damage is suspected, as these issues must be addressed before new cladding can be installed.
