Once the decision to replace the roof has been made, the next issue to settle is what type of materials will be used for the new one. There are three options, all of which are good, but each with different pros and cons. 

Metal Roofs

Metal roofing is a type of roofing that uses metal panels or tiles. It offers durability, energy efficiency, and aesthetic appeal. 

One of the biggest advantages of metal roofing is its longevity. When properly installed and maintained, a metal roof can last fifty years or more. Metal roofs are also highly resistant to fire, wind, and hail damage.

In addition to its durability, metal roofing is also energy-efficient. The reflective surface helps reduce heat absorption, which can lower cooling costs during the humid summer months of the Pittsburgh area. 

However, there are some drawbacks. One potential issue is noise--rain or hail hitting the surface of a metal roof can be loud and disruptive if not properly insulated. And while metal roofing may be able to  save money in the long run due to its longevity and energy efficiency, it typically has a higher upfront cost compared to other materials. Furthermore, while many people appreciate the sleek modern look of metal roofing, others may find it too industrial or out of place on certain architectural styles.

Shingle Roofs

Shingles are commonly made from materials such as asphalt, wood, or fiberglass. One of the biggest advantages of shingle roofing is its affordability. Shingles are relatively inexpensive compared to other roofing materials. Shingle roofs are also easy to install and repair, making them a popular choice for homeowners on a budget.

Another benefit of shingle roofing is its versatility. Shingles come in a wide range of colors and styles, making it easy to find an option that complements the style and design of a home. Additionally, shingles offer good insulation properties, which can help keep the home cool in the summer and warm in the winter.

The negatives start with durability. While shingles can last up to thirtyyears with proper maintenance, they are more susceptible to damage from wind, hail, and other weather events compared to metal. Another consideration is environmental impact--asphalt shingles are not eco-friendly and contribute significantly to landfill waste when replaced. Additionally, shingle roofs require regular maintenance, such as cleaning debris from gutters and replacing damaged or missing shingles.

Flat Roofs

Flat roofs are commonly can be made from materials such as PVC, TPO, or modified bitumen. Common in commercial roofing, they have become more popular with residential property owners in recent years. 

Flat roofs require less material and labor compared to sloped roofs, which can save money on installation costs. They also provide additional space for outdoor living areas or rooftop gardens.

Another benefit of flat roofing is its accessibility. Because they are level, flat roofs are easier to access for maintenance and repairs compared to sloped roofs. This can save time and money on regular upkeep.

But everything has a downside and flat roofs are no different. One issue is drainage--because flat roofs do not have a slope to naturally drain water, they require additional measures to prevent the water buildup that can lead to leaks or damage. And while flat roofs can last up to twenty years with proper maintenance, they are more susceptible to damage from heavy rain or snow accumulation, as compared to sloped roofs.
