5 Most Frequently Asked Questions Property Owners Ask About Commercial Roofing

Managing a commercial property comes with its own set of challenges, with the roof being one of the most significant aspects. With its importance in providing shelter and protection, it's no wonder commercial roofing frequently becomes a topic of inquiry among property owners. In this article, we'll tackle the five most frequently asked questions about commercial roofing. By delving into these key areas, we aim to provide you with an in-depth understanding to better manage your property's roofing needs.

1. What are the different types of commercial roofing systems?

Variety is certainly the spice of life, and this rings true for commercial roofing systems as well. There are several types, each with its own strengths and potential drawbacks.

1. Built-Up Roofing (BUR): This system utilizes alternating layers of roofing felt or fabrics, coupled with bitumen (asphalt or coal tar). The top layer can be a gravel or mineral surface. BUR is known for its robustness and water resistance.

2. Single-Ply Roofing: This consists of a single layer of a plastic or rubber-like compound. The two most common types are Thermoplastic Polyolefin (TPO) and Ethylene Propylene Diene Monomer (EPDM). Single-ply roofing is valued for its durability, flexibility, and energy efficiency.

3. Metal Roofing: This type of roofing is obviously comprised of metal panels or tiles. However, these are often coated for additional protection. Metal roofs are popular for their long lifespan, recyclability, and range of aesthetic options.

4. Spray Polyurethane Foam (SPF) Roofing: SPF roofing involves spraying a liquid onto the existing roof, which expands into foam and hardens into a solid layer. It provides excellent insulation and water resistance.

5. Green Roofing: This involves the creation of a "living roof" with plants and a growing medium over a waterproof membrane. Green roofs contribute positively to the environment, improve energy efficiency, and add aesthetic appeal.

2. How long does a commercial roof typically last?

The lifespan of a commercial roof depends on various factors including the type of roofing system, installation quality, ongoing maintenance, and environmental conditions. Generally speaking:

• Built-Up Roofing can last 15-30 years
• Single-Ply Roofing tends to have a lifespan of 15-20 years
• Metal Roofing can often endure 30-45 years, sometimes even more with exceptional care
• Spray Polyurethane Foam Roofing has an expected lifespan of over 20 years
• Green Roofing systems can last upwards of 40 years with proper care and maintenance
• Remember, regular inspections and maintenance can extend the life of your roof, making it a crucial part of your property management plan.

3. How often should a commercial roof be inspected and maintained?

Industry standards recommend at least two roof inspections per year, usually in the spring and fall. However, additional inspections may be necessary after significant weather events. Preventative maintenance goes hand in hand with these inspections, addressing minor issues before they become major problems.

4. How much does a new commercial roof cost?

Pricing for a new commercial roof can vary greatly due to several factors, including the type of roofing system chosen, the size of the roof, the location of the property, and the current roof's condition. Here's a rough guide for some of the common roofing types, though it's important to consult with a reputable commercial roofing contractor for an accurate estimate:

Built-Up Roofing (BUR): This robust system typically costs between $5 to $10 per square foot, including installation. BUR's multiple layers contribute to this cost, but they also provide superior durability and water resistance.

Single-Ply Roofing: This system, including TPO and EPDM varieties, can range from $3 to $5 per square foot, installed. The cost-effectiveness of single-ply roofing, along with its durability and flexibility, makes it a popular choice for many commercial properties.

Metal Roofing: Metal roofs can be more expensive upfront, with costs ranging from $5 to $12 per square foot, depending on the metal type. However, their long lifespan and recyclability can make this a cost-effective solution over the roof's life.

Spray Polyurethane Foam (SPF) Roofing: SPF roofing typically costs between $4 to $7 per square foot, installed. Despite its slightly higher cost, it provides excellent insulation and water resistance, which could lead to energy savings in the long run.

Green Roofing: Green roofs can vary greatly in cost due to their complexity, ranging from $10 to $25 per square foot, or even more for intensive systems. However, the environmental benefits, improved energy efficiency, and aesthetic appeal can justify the investment for many property owners.

In addition to the roofing system costs, you'll also need to consider potential removal and disposal costs for your existing roof. These costs can range from $1 to $5 per square foot, depending on the roof's condition and local waste disposal rates.

(Government incentives are also a massive potential bonus to look into... One notable opportunity for cost savings comes in the form of tax deductions under the Inflation Reduction Act, specifically Section 179D. Section 179D provides for a deduction of $2.50–$5.00 per square foot for the installation of an adequately energy-efficient commercial building property, which includes certain types of roofing systems in addition to HVAC, lighting, and other kinds of envelopes.)

5. Can a commercial roof be repaired, or does it need to be replaced?

Roof replacement is a significant investment, so it's understandable that many property owners ask this question. Often, a repair or restoration may be all that's needed to extend your roof's life. Roof coatings are an amazing option because of how relatively inexpensive they are, as well as how much money they can save due to lowering energy costs from their reflective properties. However, factors such as the roof's age, the extent of damage, and the cost-effectiveness of repair versus replacement will all play a role in this decision.
