Can Homeowners Use Mixed Roofing Materials in MA?

If you're preparing for a roof replacement and considering incorporating mixed roofing materials, continue reading to discover how this choice could impact your home.

Technical Considerations for Using Mixed Roofing Materials

Is your roof structure compatible with different types of roofing materials?

Different roofing materials vary in weight. For instance, metal roofs are much heavier than asphalt shingles. You must verify that your home's roof structure can handle the combined weight of these materials.

Will the combined roofing materials provide a tight water seal?

Mixing different roofing materials can make waterproofing more complex, as each material may require a unique installation method. To prevent leaks, it is essential to create a secure, watertight seal where materials meet. For this reason, different materials are typically installed in separate areas, or careful attention is given to ensuring compatibility at transition points.

Do the roofing materials expand at different rates?

Local building regulations may have stipulations regarding the use of mixed roofing materials. It's important to check the local regulations to prevent legal or compliance issues, especially with historically significant structures.

Different roofing materials expand and contract at different rates with temperature changes. Unless properly addressed during the installation, this movement can lead to structural issues over time.

Asphalt Shingles with Metal

This combination involves using traditional asphalt shingles for the majority of the roof, with metal accents or sections.  This is particularly used for areas like porches or as a contrasting design element. Asphalt shingles are valued for their cost-effectiveness and ease of installation, while metal roofing adds longevity, energy efficiency, and a modern aesthetic.

Benefits of Asphalt Shingles - Metal Combination

GAF offers products like the StainGuard Plus and StainGuard Plus PRO shingles, which aren't exactly self-cleaning but have algae-resistant properties that help maintain the roof's appearance by preventing algae growth.

• Cost Efficiency: Asphalt shingles are less expensive, making this option budget-friendly.
• Durability: Metal sections provide added durability and resistance to weather elements like snow and wind.
• Aesthetic Appeal: The contrast between asphalt and metal can create a striking visual effect.

Main Manufacturers Asphalt Shingles - Metal Combination

• GAF - Known for their wide range of asphalt shingles, and provide a metal edge for TPO.
• Owens Corning - They provide durable asphalt shingles and have ventured into metal roofing products, offering a metal underlayment for their roofing systems.

Slate and Synthetic Shingles

Slate is renowned for its longevity and classic beauty, but is heavy and expensive. Synthetic shingles, made from materials like rubber or plastic, mimic the look of slate without the weight and cost.  These shingles are often used in combination to balance cost and aesthetics.

Benefits of Slate/Synthetic Shingles Combination

• Longevity: Genuine slate can last over 75 years, while synthetic shingles offer a good lifespan at a reduced cost.
• Weight: Synthetic options are significantly lighter, reducing structural load.
• Aesthetic: The look of traditional slate with modern material benefits.

• Modern Functionality: Metal roofing enhances the roof's performance against Massachusetts' harsh weather.

Rubber Roofing with Traditional Materials

Description: EPDM (Ethylene Propylene Diene Monomer) rubber roofing is often used on flat or low-slope roofs due to its durability and ease of repair. When combined with traditional materials like asphalt or metal on pitched sections, it offers a comprehensive roofing solution.

Benefits of Rubber/Shingles Combination

• Durability: Rubber is extremely durable, and is especially good for flat roof sections.
• Cost-Effective:  Rubber roofing is generally more expensive than shingles.  Therefore, the rubber roofing is used only on the low-pitched areas of the roof whereas shingles are used on the rest.   This provides a great compromise in aesthetics, practicality, and price.
• Versatility: Works well with various traditional materials for a cohesive look.

Main Manufacturers of Rubber/Shingles Combination

• Firestone Building Products - They are leaders in EPDM rubber roofing, which can be paired with traditional materials for combined projects.
