Differences Between a Residential and Commercial Roof

Differences Between a Residential and Commercial Roof

Both residential and commercial rooftops have similar characteristics, such as a strong support deck, weatherproofing and insulation. However, five primary differences between a residential and commercial roof do exist.

1. Size

Every commercial building or home is different. However, roofs of larger buildings typically take up more room on a commercial site than on residential property. If it’s a flat roof, it might extend further out to the edge of a lot line than a sloped residential roof would.

2. Design

Professional contractors typically position a commercial roof at a flatter angle than residential roofs. It might have a slight slope for water drainage, but the almost-flat design allows for ease of inspection and repair without requiring maintenance workers to stay on a power lift. Residential roofs often are steeper for various reasons, such as for easy water runoff and to conserve lot space or not allow debris accumulation on top of them.

However, industrial plants, restaurants or other large buildings typically cost more to construct than a home. Therefore, these types of commercial buildings usually have a simpler roofing design than a residential dwelling would.

3. Materials

You could interchange residential and commercial roofing materials with one another. For instance, both wood and metal structural decks can be used on private residences and public office buildings. You also can use asphalt or a form of rubber or plastic for the top weatherproof layer.

They also both have similar forms of insulation or UV and moisture protection. However, your business might have extra needs, such as testing room climate control, that are not always possible using roofing materials made for homes. Commercial buildings might also require more soundproofing and security too, which can come from choosing durable rooftop layers.

Residential roofs often are steeper for various reasons, such as for easy water runoff and to conserve lot space or not allow debris accumulation on top of them.

4. Obstacles

A commercial roof might have round smokestacks or square vents installed on it. A home also might, but some houses just have a chimney and maybe one or two air escape systems. On the contrary, a business site might have several vents on it as well as water pipelines for drainage that are more complex than what you would see on a single-family home.

5. Installation Time

Because of the massive size of many commercial buildings, these roofs could take more time to install than residential ones. It’s part of the reason that companies opt for simple rooftops that don’t have all kinds of fancy carvings in their frames.
