Residential vs Commercial Roofing: What are the Differences?

Residential roofing typically involves materials such as asphalt shingles, wood shakes, and metal panels, designed for homes with pitched roofs, focusing on aesthetic appeal and durability. In contrast, commercial roofing often uses materials like single-ply membranes (TPO, EPDM), built-up roofing (BUR), and modified bitumen, tailored for flat or low-slope roofs on larger buildings, prioritizing durability and energy efficiency. Commercial roofs usually require more maintenance and have more complex installation processes due to their size and structure.

At Northeast Exteriors, it's important to know the differences between residential and commercial roofs. Each type has different purposes and needs specific designs, materials, and maintenance. Let's explore these differences to help you choose the right roof for your needs.

Key Takeaways:

• Roof Design: Residential roofs are typically steeply pitched and smaller in size, while commercial roofs are often flat or low-sloped, covering larger areas and accommodating various installations like HVAC systems and skylights.

• Roofing Materials: Residential roofs commonly feature asphalt shingles, wood shakes, and tiles, whereas commercial roofs utilize materials such as modified bitumen, single-ply membranes (PVC, TPO, EPDM), and sprayed polyurethane foam.

• Installation and Maintenance: Commercial roofs are more complex and time-consuming to install due to their size and additional layers, requiring more frequent inspections and maintenance compared to residential roofs.
