Residential and Commercial Roofing Experts

At C.K. Lewis Construction, Inc., we help our Maryland clients create the roofing solution that fits the needs of the site and works within their budget. There are many differences between residential and commercial roofing. We’ll help you determine which products are right for your project and situation.

Because there are many techniques and materials that can be used in a residential or commercial roofing project, the needs of each type of roof can vary greatly. But no matter which materials you use, or which type of structure you are roofing, it’s important to use experienced roofing contractors who understand each site’s special needs and constraints.
 

Residential vs. Commercial: Roofing Design

One of the biggest differences between residential and commercial roofs is the size and design. Because commercial roofing often covers thousands, or even tens of thousands of square feet, it is usually low sloped or flat. Commercial roofs often support hefty HVAC systems that are regularly service and are therefore subject to frequent foot traffic. Flat commercial roofs must also be able to withstand heavy snow loads.

Residential homes are generally smaller, and usually feature sloped roofs designed to shed water and snow. These roofs are rarely walked on, and usually require much less maintenance.

Installation of Residential vs. Commercial Roofs

Installing a residential roof is usually a straightforward process. The residential roofs that C.K. Lewis Contractors work with are generally smaller and can be built in a day or two. For some residential projects, the use of specialized roofing materials or exceptionally complex construction may require additional time to install.

When our team works with commercial roof installations, our roofing experts must consider the impact of external piping, air flow systems, and more. Commercial roofs are also much larger and use a more complicated combination of materials. For example, the materials and adhesives used on flat roofs can require days to dry or cure. Commercial construction is also subject to additional regulations and inspections. It can take weeks to complete.

Roofing Materials

There is a wide variety of roofing materials available for use on both residential and commercial buildings in Maryland. Any roofing project will use a variety of substrates and materials that work together to provide protection from the elements. In Maryland, roofing not only keeps buildings dry, it must also be able to withstand a wide range of temperatures, heavy rainfall, snow, and ice. In some areas, roofs must stand up to the challenges of salty sea air and saltwater corrosion.

Asphalt for Commercial and Residential Roofs

Asphalt and coal-tar pitch are the bituminous materials used in built-up roofing, or asphalt shingles. Asphalt is usually the preferred material for sloping roofs, while coal tar is preferred for flat roofs and commercial applications.

Wood Shingles for Residential Roofing

Wood shingles are usually made with decay-resistant wood such as red cedar or cypress. Wood shingles may be machine-sawn or hand-split shakes. Wood shingles are often treated with fire-retardant coatings and are one of the less costly roofing materials. This is also a popular choice for historic, rustic, or seaside homes.

Metal Roofs for Residential and Commercial Roofing

Metal roofs are durable choices for flat, commercial roofs, but are becoming a popular choice for pitched roofs and residential homes as well. If used on flat roofs, the sheets are usually soldered or welded together. On pitched roofs, they are attached with nails or screws.

Made of galvanized iron, copper, aluminum, steel, and terne plate, metal roofs come in a rainbow of colors to suit any aesthetic. Metal roofs are often a cost-effective, long-lasting roofing choice for residential homes. While a metal roof may be the more costly choice for commercial installations, it is a durable and reliable roofing choice that can last for decades.

Slate, Clay, and Cement Roofing Tiles for Residential and Commercial Roofing

Tiles made from slate, clay, or cement can provide a look and feel that no other roofing materials can offer. Tile roofs tend to be heavy, durable, fireproof, and more expensive. They must be applied to sloping roofs, lapped over the proceeding courses, and attached with nails.

While clay tiles are rarely appropriate for areas with cold winters, cement tiles can look like clay, and are a practical choice for colder climates. Slate tiles represent a significant investment but provide historical accuracy for many types of buildings. When properly maintained, high-quality slate tiles can last for centuries.

Glass and Plastic Roofing for Commercial and Residential Applications

When a building has skylights, an atrium roof, or greenhouse features, glass or plastic roofing expertise is needed. Because glass and plastic are not fire-resistant, wire reinforced glass or fiberglass-reinforced acrylic sheets are usually recommended.
