You could say that your roof is your home’s “crowning glory.” Not only does it offer protection to your house, but it reflects a significant portion of your its value. Roof damage, whether it is minor or significant, can take a toll on your budget and home equity. Roof problems can take many forms — loose shingles, intermittent holes, hail damage or complete devastation from a major weather event or house fire. Damage isn’t the only reason to replace your roof. The average lifespan of a residential roof is 25 years.

Roofs on commercial properties are not immune to problems and can be even more prone to damage, particularly if they are in a location with harsh elements. Commercial properties are also more vulnerable to fires and industrial damage. The roofs of commercial properties don’t last quite as long; around 22 years. In both cases, the longevity of a roof depends on the materials used and the climate.

Type of residential roofs:


Roof tiles are made of clay, ceramic, concrete or slate and they are commonly used in Mediterranean-style architecture. Tile roofs are fireproof and can withstand heavy winds. They also offer better ventilation then asphalt roofs. Tile roofs are the most expensive, but the longest-lasting over time.


Asphalt shingles come in three varieties: three-tab, fiberglass and architectural-style. Asphalt shingles are the most popular because they are the least expensive, while architectural-style asphalt shingles are the most attractive and most expensive of this group. Other types of materials used for shingles include metal, composite, rubber and solar. Asphalt shingles are known for their durability and longevity.

Wood Shakes:

Wood shake shingles are frequently the preferred style of HOAs because of their high-end appearance. These shingles are crafted from aged cedar or redwood and are cut so that the natural grain is exposed, which creates their elegant appearance. Wood shakes last longer than asphalt but require more maintenance. These days, most wood shake shingles are treated to increase their fire resistance.

Types of commercial roofs:

Modified bitumen:

Modified bitumen is asphalt roofing material with added membranes of fiberglass or polyester. This gives the roof extra strength and this compound is ideal for commercial buildings that have roofs that are either flat or have a low slope. Modified bitumen is water-resistant and provides superior weather protection. While more expensive than regular asphalt, this roofing compound is less expensive than others.


TPO (thermoplastic olefin) roofing is a popular choice for commercial buildings because of it’s relatively low cost and energy efficiency. It’s a single application compound consisting of three layers, is easy to install and costs less than other commercial roofing materials. TPO is more common in states with warmer temperatures because of its cooling properties. Color choices are limited to white, light grey and tan but lower A/C bills may outweigh the lack of design options.


EPDM is a synthetic rubber roofing membrane made of ethylene and propylene and is a popular choice for commercial buildings across the country. It is primarily used on flat roofs. EPDM is the least expensive roofing material for commercial buildings because it’s lightweight and easy to install. Other advantages include puncture-resistance, fire-resistance and the ability to withstand extreme temperatures and exposure to strong winds and hail.


Asphalt shingles are frequently used for commercial buildings for many of the same reasons as for homes. They are lightweight, durable, inexpensive and have a long lifespan. Asphalt shingle properties have evolved over the years and are now more energy-efficient, wind-resistant and available in a wider selection of colors. They are also now more environmentally-friendly and made of recycled materials; important considerations for businesses that want to reduce their carbon footprint.
