The Importance of Understanding Re-roofing

For commercial property owners and building managers, maintaining a functional and safe building is a top priority. One critical aspect of this task is ensuring that the roof of the building is in excellent condition. Over time, weather conditions, natural wear and tear, and unexpected events can lead to the need for a roof upgrade. This blog will explore the concept of commercial roof re-roofing, offering insights into its advantages and potential challenges. By the end of this post, you'll know if re-roofing is the right choice for your commercial property.

What is Re-roofing?

Re-roofing is the process of installing a new roofing system over an existing one. This method is often considered by property owners looking for a cost-effective and efficient way to address roofing issues without fully removing the current roof structure. Unlike a complete tear-off, which involves stripping all existing materials down to the roof deck, re-roofing adds an additional layer to reinforce the existing structure.

This method is suitable for various types of roofing systems, including flat and sloped roofs. For commercial properties, re-roofing can provide benefits such as improved durability and weather resistance. However, it is important to note that re-roofing may not be suitable for all situations, especially if the existing roof has significant damage or structural issues.

Legality of Re-roofing a Commercial Roof

Before deciding on re-roofing, it is crucial to understand the legal aspects involved. Different regions have varying regulations regarding the number of roofing layers allowed and the conditions under which re-roofing is permitted. It is essential to consult local building codes and ordinances to ensure compliance with the law.

In some areas, building codes may restrict re-roofing if the current roof already has two or more layers. Additionally, specific materials might be required to meet fire safety and energy efficiency standards. Collaborating with knowledgeable roofing contractors can ensure that your re-roofing project adheres to all necessary regulations, avoiding potential legal and safety issues.

Exploring Re-roofing Options

When considering re-roofing commercial roof, understanding the available options is vital. Various materials and techniques can be employed depending on the existing roof type and the desired outcome. Some common re-roofing materials include asphalt shingles, metal roofing, and rubber membrane systems. Each material offers unique benefits and considerations, such as durability, ease of installation, and cost-effectiveness.

For example, metal roofing is known for its longevity and resistance to harsh weather conditions, making it a popular choice for commercial properties. On the other hand, asphalt shingles may be more budget-friendly but could require more frequent maintenance. Consulting with experienced commercial roofers can help you select the best option for your building's specific needs.

Benefits of Re-roofing

Re-roofing presents numerous advantages for commercial property owners and managers. One of the primary benefits is cost savings. Since re-roofing involves adding an additional layer rather than a full tear-off, labor and material costs are generally lower. This makes it an attractive option for those operating on a tight budget.

Another advantage is the reduced time required to complete the project. With a shorter installation process, disruptions to your business operations can be minimized, allowing you to maintain productivity while upgrading your roof. Additionally, re-roofing can enhance the overall appearance of your property, providing a fresh and updated look without the need for extensive renovations.

How Much Does a Commercial Re-roof Cost?

The cost of a commercial re-roof project can vary significantly based on several factors. These include the size of the roof, the materials used, the complexity of the project, and the location of your property. On average, re-roofing tends to be more affordable than a complete tear-off, but it is important to obtain detailed estimates from reputable Vancouver roofing companies.

Be sure to consider long-term maintenance and potential repairs when evaluating the cost of re-roofing. While the initial investment may be lower, choosing high-quality materials and skilled commercial roofers can help prevent future issues and maximize the lifespan of your new roofing system.

• Modified Bitumen
• Metal Roofing
• Green Roofing
• Spray Foam Roofing
• Roof Coatings

By the end of this post, you'll have a clear understanding of each system's advantages and considerations, allowing you to choose the right roofing solution for your needs.

1. Built-Up Roofing (BUR)

Built-Up Roofing (BUR) is one of the oldest and most reliable forms of commercial roofing systems. It consists of multiple layers of asphalt, felt, and gravel, creating a sturdy and durable roof that can withstand harsh weather conditions.

Durability and Longevity

One of the primary advantages of BUR is its durability. With proper maintenance, these roofs can last up to 30 years or more. The multiple layers provide excellent resistance to UV rays, extreme temperatures, and heavy rain, reducing the risk of leaks and damage over time.

Cost-Effectiveness

While the initial installation cost of BUR may be higher compared to some other roofing options, its long lifespan often makes it a cost-effective choice in the long run. Property owners can save on frequent repairs and replacements, making it a wise investment for commercial buildings.

Suitable Environments

BUR is ideal for flat or low-slope roofs and is commonly used in urban settings, where its ability to absorb heat can contribute to energy efficiency. However, its weight may require additional structural support, so it's essential to consult with a qualified roofing contractor before installation.

2. Single-Ply Membrane

Single-Ply Membrane roofing systems have gained popularity for their ease of installation, flexibility, and energy efficiency. These roofs are made from a single layer of synthetic material, usually either TPO (Thermoplastic Olefin) or EPDM (Ethylene Propylene Diene Monomer).

Energy Efficiency

One of the standout features of Single-Ply Membrane systems is their energy-efficient properties. TPO membranes, in particular, are designed to reflect sunlight and reduce heat absorption, which can lead to lower cooling costs for commercial buildings.

Quick Installation Process

Green roofs are known for their ability to improve air quality, reduce stormwater runoff, and support local biodiversity by providing habitats for birds and insects. These environmental advantages align with the growing trend of sustainable building practices.

Insulation and Energy Efficiency

In addition to their ecological benefits, green roofs offer excellent insulation properties. The layers of soil and vegetation help regulate indoor temperatures, reducing the need for heating and cooling systems and ultimately lowering energy costs.

Aesthetic Appeal

Beyond their environmental and energy-efficient attributes, green roofing systems enhance the visual appeal of commercial buildings. They can be designed to include pathways, seating areas, and native plants, creating a serene and inviting atmosphere for employees and visitors.

6. Spray Foam Roofing

Spray Foam Roofing systems are a modern solution gaining traction in the commercial sector. This roofing option involves applying a layer of polyurethane foam, which expands upon contact to create a seamless and insulated waterproof barrier.

Seamless Design

One of the primary advantages of Spray Foam Roofing is its seamless nature. Unlike traditional roofing materials that may require joints and seams, spray foam forms a continuous layer that eliminates potential leak points, enhancing the roof's overall durability.

Excellent Insulation Properties

The insulation properties of Spray Foam Roofing contribute to energy efficiency by regulating indoor temperatures and reducing the need for heating and cooling systems. Additionally, building owners may benefit from reduced energy costs over time.

Quick Installation Process

Spray Foam Roofing can be installed quickly, often in a single day, making it an attractive option for commercial property owners looking to minimize operational disruptions during installation.

7. Roof Coatings

Roof Coatings are a cost-effective solution for extending the lifespan of existing commercial roofing systems. These coatings, typically made from acrylic, silicone, or polyurethane, are applied as a liquid and cure to form a protective layer over the roof's surface.

Cost-Effective Maintenance

One of the main reasons property owners choose roof coatings is their cost-effectiveness. Instead of investing in a complete roof replacement, applying a roof coating can extend the life of the existing roof, saving capital in the long term.

Improved Energy Efficiency

Many roof coatings are designed with reflective properties, helping to reduce heat absorption and lower energy costs for cooling commercial buildings. This feature aligns with the increasing demand for energy-efficient building solutions.

Protection Against Weather Damage

Roof coatings serve as a protective barrier against UV rays, rain, and debris, preventing premature deterioration of the underlying roofing material. This added layer of protection can significantly enhance the roof's overall durability and performance.

Choosing the right roofing system for a commercial property is a critical decision that requires careful consideration of various factors, including durability, energy efficiency, and overall cost. Understanding the key differences between the various types of commercial roofing systems is essential for making an informed choice that meets the specific needs of your building.

By investing in a high-quality roofing solution and working with experienced commercial roofers, property owners can ensure that their roofs provide reliable protection and contribute to the long-term value of their investments.

Commercial roofing represents a highly specialized industry wherein roofing experts utilize a variety of construction materials and methods.  To believe that all commercial roofs are constructed from the same materials would be incorrect.  So then, when it comes to commercial roofing practice, what are some of the most common roofing materials and how would you choose the best materials for your building?  Let’s take a closer look at the most common material for commercial roofing and some of the reasons they are selected for various projects.

There are a variety of commercial roofing materials but we will discuss three of the most common including ethylene propylene diene monomer (EPDM), thermoplastic polyolefin (TPO), and polyvinyl chloride (PVC).  Depending on factors such as cost, climate, and durability, roofers will recommend materials that most effectively meet your needs.

EPDM roofs are sometimes known as rubber roofs and these materials are commonly selected because they provide great value.  Not only are EPDM roofs relatively inexpensive, they are easy to install, lightweight, and relatively easy to maintain.  With a lifespan of approximately 20 years, EPDM roofs provide reasonable durability as well.  However, EPDM roofs are not the most common choice for those concerned with aesthetics – these roofs essentially look like black, rubber coverings.  Since they are black, they also absorb heat meaning cooling costs in the summer can be considerably higher.  With respect to effects from weather, EPDM roofs are more susceptible to punctures from events such as hailstorms or falling branches.  Still, punctures are easily repaired and major problems can be avoided with appropriate maintenance.

TPO roofs are increasingly popular as a low cost option that reflects heat and reduces cooling costs.  These are lightweight roofs that are resistant to corrosion, prevent algae and mildew growth, and feature heat-sealed seams that are more resistant to leaks.  Nevertheless, TPO roofs are not fire resistant which means fire retardants need to be integrated into your roofing system.

Finally, PVC roofing features two layers of material reinforced with polyester between the layers.  Additives in the layers make PVC roofs resistant to UV damage, and like EPDM and TPO roofs, they are lightweight and easily installed.  PVC roofs make an excellent choice for flat or low-slope roofs as they are quite durable and stand up well to moisture, fire, wind, and even chemicals.  Installing PVC roofs requires a heat welding process which permanently bonds the roofing sheets and securely attaches seams.  On the other hand, PVC roofs are known to shrink which ultimately creates pressure on the seams.  Additionally, PVC roofs are relatively expensive and they are not ideal for colder temperatures.  PVC repair can be challenging so regular maintenance becomes especially important.

When selecting the roofing material for your commercial building, it is always highly recommended that you work with roofing experts and get their advice.  Roofing contractors have the knowledge and experience to fit your roof with the right materials.

In general, commercial and industrial building feature flat roofs, but that’s not to say all flat roofs are the same.  There are a number of flat roof options for commercial and industrial buildings and each have their pros and cons.  Perhaps one of the best commercial roofing products today is the sprayed polyurethane foam roof, though it is not commonly installed.  Built-up roofs, modified bitumen roofs, PVC roofing, and single ply EPDM roofing structures tend to be more popular.  Let’s take a look at each of these roofing products and some of their benefits and disadvantages.

Built-up Roof

Built-up roofs dominate commercial and industrial roofing because they are inexpensive and provide a nice aesthetic.  You would recognize a built-up roof as it is typically covered in gravel.  These roofs feature multiple layers and provide great insulation, but they tend to be quite heavy.  Because of the relative weight of built-up roofs, they are not always an appropriate option for a commercial or industrial facility; in fact, these roofs usually require reinforced joists which often results in increased construction costs and time.

Modified Bitumen Roof

Modified bitumen roofs are a popular single-ply roofing system that require highly specialized installation skills.  Nevertheless, modified bitumen roofing systems are one of the eco-friendliest flat roofing options because they can help reduce energy costs.  Indeed, these roofing systems reflect heat from the sun so help to reduce the cost associated with cooling the building. 

PVC Roofs

Durable and easy to install, PVC roofing resists water pooling making them a popular choice for wet climates.  However, PVC installation involves applying the roofing system from rolls so there will be seams throughout the roof surface.  Each of these seams can potentially fail and result in leaks.  So, while PVC roofing systems are durable, they are not as effective as polyurethane foam roofs.

Single-ply EPDM

EPDM systems are constructed from a rubber compound making them quite durable – in fact, they are commonly regarded as one of the most long-lasting flat roofing products available.  However, like PVC roofs, EPDM systems also have seams so if they are not installed properly they can be very vulnerable to leaks.  Maintenance at seams can be costly, and these roofs are known to be require more maintenance than other flat roofing systems.

Spray-Applied Roof Coating

Polyurethane spray-applied foam roofing systems are possibly the best commercial roofing products on the market today.  Featuring seamless application, these roofs incorporate most of the benefits of the other roofing systems discussed and few of the drawbacks.  These roofs resist water pooling for better durability but also have reflective properties to reduce heating and cooling costs.  Most importantly, spray-applied roofing systems are among the most sustainable.  Though they tend to cost more to install, their durability and easy maintenance will save building owners over the lifespan of the roof.

Commercial roofing is a much more complicated industry than many of us are aware.  Though there are 2 standard types of commercial roof – low slope and steep slope – there are actually a wide range of materials utilized in commercial roofing.  We’ll consider these two main types of commercial roof, if only to help organize the discussion.  But, before we start, let’s define low slope and steep slope roofs.

First, low slope roofs are those that require weatherproof or waterproof membranes as they feature slopes at 14° or less.  On the other hand, steep slope roofs allow for water-shedding as their slopes are greater than 14°.  As such, these types of roofs are often constructed from different materials.  Let’s have a closer look.

Low Slope Roofs

A low slope commercial roof is usually constructed from one of four different types of material:

1. Metal panels
2. Single-ply membranes
3. Built-up roof membranes
4. Spray polyurethane foam-based roofs

Metal panels are highly versatile.  They are an excellent option for commercial, institutional, and industrial buildings because they’re durable and relatively cost effective. 

Single-ply membrane roofing refers to pre-manufactured sheet membranes that are either thermoplastic or thermoset.  These sheets vary in thickness and are secured to a roof system to provide protection against inclement weather.  Often referred to as “rubber roofing,” these systems are flexible and durable.

Built-up roof membranes have been utilized in roofing for more than a century and are commonly known as tar and gravel roofs.  They are composed of alternating layers of bitumen and fabric for reinforcement to create a protective roofing membrane.  These roofs are affordable, durable, and relatively easy to maintain.

Finally, spray polyurethane foam-based roofs can be used on new commercial roofs or installed over an existing roof.  These systems can replace most roofing systems and feature a spray-on foam that seals and protects your commercial roof. 

Steep Slope Roofs

Now that we have a better idea about roofing materials for commercial low slope roofs, let’s turn our attention to steep slope roofs.  There are 5 common types of materials for these kinds of commercial roof:

1. Asphalt shingles
2. Metal roofing
3. Wood shakes and shingles
4. Slate
5. Clay or concrete tiles

Asphalt shingles are the most popular type of residential roofing system in North America, but they’re also excellent applications for steep slope commercial roofs.  They’re affordable and easy to maintain while also providing lasting protection.

Metal roofing is adequate for both steel and low slope commercial roofs.  Though more expensive than other types of roofing systems, commercial metal roofs hold up well to all kinds of weather.  Not only are they flexible with respect to their effectiveness in different climates, they are also highly durable.

Wood shakes and shingles are an attractive roofing option even for commercial properties.  If aesthetic is important, these are definitely an excellent options.  But wood shakes and shingles are durable as well.  They withstand severe storms and high winds, and they’re also energy efficient.

Slate roofing for commercial steep slope roofs are regarded as high quality, long lasting systems.  As a natural stone product, they’re aesthetically pleasing but also highly fire resistant and environmentally friendly.  However, slate roofs tend to be quite heavy and costly.

Finally, clay or concrete roofing systems are also stylish and durable.  They tend to be heavier than other roofing systems, and they’re also quite expensive.  That being said, they also are a great choice for all climates, and they’re fire resistant too!

Sometimes you don’t have the luxury of scheduling your roof replacement.  In the event of an emergency, you’re likely to find roofing repairs or replacement are considerably more expensive – not because roofers are cashing in at your time of need, but because emergency roofing work typically comes up during a roofer’s busiest season.  Of course, emergency roofing repairs are not always avoidable, but with regular maintenance and inspections you can ensure that your roof will survive seasonal weather challenges so that you can schedule repairs or replacement during the roofing off-season when rates tend to be lower.

So when is the best time to reroof?  Obviously, roofing contractors are available year-round to help homeowners with their roofing needs.  As a homeowner, you may think it is in your best interests to delay roofing replacement as long as possible, but it’s much more important to consider the quality of your roof when deciding when to schedule a replacement.  This is why regular maintenance and repairs are so important.  An annual roofing inspection will reveal minor problems that can be repaired before they become catastrophic damage.  Moreover, your roofing contractor will likely be able to predict when your roof will need to be replaced.

A good contractor will always try to coordinate roof replacement or major roofing repairs with their offseason.  Late summer and fall tend to be the busiest months of the year for roofing companies.  As we prepare for the harsh realities of winter weather, we want to be sure our roofs are in good condition, so it makes sense that roofers would be busiest leading up to the winter months.  Moreover, late summer weather tends to be more predictable and temperatures are cooler so it’s easier to schedule and conduct repairs.  However, being the busiest months for roofers also means it can be difficult to find available contractors.  Roofing supplies also tend to be more expensive during the late summer and early fall months, so homeowners will likely find the peak season for roofing to be the most expensive.

On the other hand, scheduling major roofing work during the winter months can be easier since roofers tend to be less busy at this time of year.  Asphalt shingles can be installed in any temperature without affecting their warranty, so if you live in a dry environment, winter might be a great time to schedule your roofing work.  Unfortunately, winter weather can be unpredictable in most climates making it challenging for roofers to complete a project in a timely manner.  Interruptions from weather can definitely impact the cost of your roofing replacement.

As you can see, there are pros and cons to conducting a roof replacement at any time of the year.  Ideally, you want to have the luxury of planning ahead whenever it comes to major roofing projects.  So what does that mean?  Ensure you schedule regular inspections and maintenance for your roof so that you can effectively plan major repairs or replacements.
