Metal Roofing Over Shingles: Pros and Cons: Fast-Track Guide to Understanding Metal Roofing Over Shingles

Considering metal roofing over shingles? You're not alone! This option is gaining popularity for many homeowners looking for a durable and efficient roofing solution. So, what are the pros and cons of this roofing strategy?

Pros of Metal Roofing Over Shingles

1. **Durability**: Metal roofing is known for its longevity, often lasting 40-70 years. This durability provides long-term savings, as you won’t have to replace your roof as frequently.

2. **Energy Efficiency**: Metal roofs reflect heat, which can reduce cooling costs by up to 25%. This is particularly beneficial in warmer climates where energy bills can skyrocket during the summer months.

3. **Weight and Installation**: Installing metal roofing over existing shingles saves time and labor costs. Metal is lighter than many other roofing materials, meaning it can often be placed directly over the shingles without additional structural changes.

4. **Aesthetic Variety**: Metal roofing comes in various styles and colors, allowing homeowners to choose materials that match their home’s architecture.

Cons of Metal Roofing Over Shingles

1. **Cost**: The initial investment for metal roofing can be higher compared to traditional asphalt shingles. Homeowners may need to weigh long-term savings against short-term costs.

2. **Noise**: Metal roofing can be noisier during heavy rain or hail. While this can be mitigated with proper insulation, it’s an important consideration for many.

3. **Expansion and Contraction**: Metal roofing materials expand and contract with temperature changes. If not properly secured, this can lead to issues such as warping or lifting.

4. **Limited Lifespan of Underlying Shingles**: If your shingles are significantly aged or damaged, adding metal roofing may trap moisture, leading to potential decay and the need for earlier replacement.
