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.

If you are installing a new roof on your home or commercial or industrial building, the roof is most likely covered by some kind of roofing warranty. One would think that a warranty is a warranty and there isn’t much more to consider when it comes to a roofing warranty, but that’s not actually the case. In fact, roofing warranties can be fairly complicated and it’s important as the building owner that you understand what type of warranty covers your roof, the terms of the warranty, factors that may void the warranty, and also your maintenance responsibilities. As such, it is always important to ask for some details about the roofing warranty before you sign a contract to install a new roof. So then, what can you expect from your roofing warranty?

Types of Roofing Warranty

You may be surprised to learn that there are two basic types of roofing warranty: contractor warranty and manufacturer warranty.  The contractor warranty is provided by the contractor that installs your roof whereas the manufacturer warranty is provided by the company that makes your roofing material.  Each type of warranty can vary significantly from one company to another, so always check the fine print.  Typically, a contractor offers a warranty that covers workmanship while manufacturers’ warranties cover materials or sometimes the roofing system.

In your review of your warranty, you may also learn of material-only, labour-only, and system warranties.  Material-only roofing warranties are less expensive but apply only to material defects that cause early deterioration of roofing systems.  These warranties include the roof membrane but not flashings, adhesives, or edges.  With a material-only warranty will cover the costs of material replacement but not the labour costs associated with repair.  Labour-only warranties are generally provided by contractors and cover labour costs associated with roof repair. Finally, the most expensive but best roofing warranties are roof system warranties.  These warranties protect you completely and cover labour and material costs including costs for accessories such as flashing and edges.

To confuse things further, labour warranties are different from roof workmanship warranties.  While a labour roofing warranty will cover the costs associated with repairing a damaged roof, it does not cover repairs resulting from installation problems.  Alternatively, workmanship roofing warranties protects you in case of installation defects.

Terms of Roofing Warranty

As you may have guessed, the terms of your roofing warranty will depend on the type of warranty you have and also the company providing the warranty.  Before you purchase a new roof, ask what is covered and for how long.  Make sure to also ask about labour and materials and what kinds of defects are typically covered and whether there is any coverage for damage from weather.

Also, take note that there are typically maintenance responsibilities that are outlined in your warranty.  If you fail to maintain your roof, your warranty may be voided.  Additionally, roofing warranties are not likely to cover damage from standing water, damage to interior structures, and also so-called “acts of God” (i.e. extreme weather or events such as tornadoes, floods, and fires).

Choosing a residential roofing company is a decision that should not be taken lightly.  Roofing repairs and replacement can not only be costly, but they are crucial to protecting your home, belongings, and most importantly – your family.  So, when selecting a roofing contractor, what should you consider?  From the company’s reputation and experience to your preferred working style, there are many things to look for in a residential roofing company.  Let’s take a look at some of the most important factors to consider.

Reputation

When first shortlisting candidates for a residential roofing company to complete your roofing project, you should consider the reputation of the contractor.  Ask friends, family, and colleagues if they can recommend a good contractor, but also consider how long that roofing company has been in business and their portfolio of work.  Not only do you want to know that the company has experience with your type of project, but working with a roofing contractor that has established roots in your community ensures that they will still be around if anything goes wrong with your roofing repairs or replacement.

This means that your residential roofing company should have a bricks-and-mortar location that includes a business address, phone number, and email.  Nowadays, most companies will also have a website that can direct you to testimonials from past customers, contact information for the roofer, and examples of the kind of experience they have.  All these elements suggest you are working with an established and reputable roofing contractor that is committed to serving its customers.

Staff

Some residential roofing companies hire subcontractors to complete roofing repairs and replacement, and this may be an early red flag.  Subcontractors are hired on one job at a time, and if the roofing company does not have a long-standing relationship with said subcontractor quality control may be an issue.  The best way for a residential roofing company to ensure exceptional workmanship is to hire and train their staff to meet or exceed their expectations of roofing quality.

Estimates

Any reputable roofing contractor will provide a written estimate and detailed contract for all roofing work that needs to be done.  Job specifications should be made explicit and the cost of materials and labour should be clearly outlined before you begin a roofing project. 

Liability Insurance

The next thing you want to know before you hire a residential roofing company is that they have adequate liability insurance to protect your property and their workers.  Ask your roofer if they can provide proof of liability insurance before agreeing to work with them.

Ongoing Maintenance and Emergency Service

Many roofing contractors will offer warranties for their workmanship that differ from the warranties for materials used in the project.  If there are problems with your roof that arise from errors made by your contractor or their staff, you want to be sure that repairs will be covered.  Likewise, always try to work with a residential roofing company that provides service outside usual business hours in case an emergency arises.

Determining the appropriate frequency of roofing inspections is not what you would call an exact science.  There are a number of factors that will influence how often your roof should be inspected from the materials used in its construction to the age of the roof, not to mention the impact of weather such as wind, snow, rain, and sun.  As the homeowner, you should ideally commit yourself to giving your roof a quick once over at least twice a year where you look for signs of damage, but you will also want to schedule regular professional roof inspections.  Let’s take a closer look at some of the factors you should consider when determining how often your roof should be inspected.

Roofing Components

The most common exterior component of your roof is likely a layer of shingles – generally these are made from asphalt or wood.  But, there are many other roofing materials including metal roofs, ceramic tiles, and more.  Additionally, your roof is composed of more than that external layer; and all these components require regular inspections and maintenance.  For example, a roof is held up by trusses that are then covered by a sheeting material to provide the main structural support for your roof.  Then of course there is an underlay upon which this exterior surface (i.e. singles) are installed.  Additionally, roofing features are surrounded by flashing and you will have gutters that need to be inspected as well.  So, while a homeowner may be well poised to identify superficial signs of damage or deterioration, only a qualified professional will have the skills to thoroughly inspect your roof.

Inspection Schedules

One of the most obvious times to schedule regular inspections is after the harshest season in your climate.  Many homeowners want to know how their roofs have held up to winter weather or stormy seasons.  And it’s true, scheduling inspections after severe weather can help prevent future damage and ensure your roof is in good condition.  Alternatively, some professionals recommend inspections just before you expect the worst weather – once again, this helps to ensure your roof is in good stead for the coming harsh weather.  However, these shoulder seasons also tend to be busier for roofers and inspections may cost more. 

Still, perhaps the main factor that influences how often your roof needs inspection is the materials used in its construction.  Depending on the type of material, you can expect different rates of deterioration.  More specifically, guidelines dictate that asphalt, composite, and wood shingle roofs should be professionally inspected every 1-3 years, depending on the age of the roof.  Older roofs should be inspected more frequently.  On the other hand, a ceramic tile roof may reliably protect your home with inspections scheduled every 3-5 years, again depending on the age of your roof.

As you can see, there are many factors that influence how often your roof should be inspected, but there’s no question that regular inspection can extend the lifespan of your roof and prevent leaks that cause damage to interior structures.  And one more point to note – if you are not confident managing your own twice-yearly checks, don’t hesitate to work with a professional.

Look for damage around the area of the roof that is leaking.  Damaged, misshaped, curled, or missing shingles may all be the source of a leak.  Search areas of your roof where two surfaces meet and make sure there are now breaks or gaps in the shingles, caulking, or flashing.  Once you find the source of the leak, there are several ways you can repair it.  For example, if shingles are curled up, you can reattach them with asphalt roof cement or compound caulking.  If the weather is warm, you should be able to easily straighten the shingles, but in cold weather shingles become more brittle and should e softened before adjusting them.  A propane torch with a flame-spreader nozzle can be carefully run over the shingle to soften it.  Shingles can then be reattached by applying a generous amount of roof cement at each corner of the shingle and by pressing it firmly to the roof.

Torn, broken, or rotten shingles should be replaced.  Start by lifting the edges of the old shingle and removing nails with a nail puller or pry bar.  Slide the shingle free and be careful to remove any dried on roof cement.  If your shingles have been blown off in a storm, you will still need to remove remaining nails.  Next, you can slide the new shingle under the remaining shingles and align it according to the surrounding shingles.  You will need to fasten then new shingle with galvanized roofing nails at each of the top corners of the shingle.  Next, cover nail heads with roof cement and then cover the top of the shingle with the overlapping, original shingles.  You can use a bit more roof cement to attach the old shingles to the new one. 

Remember that when you are doing roof repairs, you should only work on a sunny day when the roof is completely dry.  Always follow standard safety instructions and use a harness when you are on the roof.  Finally, rubber-soled shoes provide excellent traction and are the safest footwear when you are working on a roof.

Roofing contractors will tell you that one of the leading contributing factors to roof deterioration is improper maintenance. Homeowners often expect that their roof is in good condition if it can survive major weather events; but if you have to wait for a storm to learn that it needs repairs, you’ve waited too long. Even minor leaks during a moderate rainstorm may be a sign of more significant problems; and since your roof provides important structural support to your home and protection to your belongings, it is vital that you ensure it is cared for properly.

Roofing materials and fixtures should be inspected regularly to spot the early signs of damage and prevent leaks and more significant issues.  Just as you would carefully clean and protect the internal aspects of your home, you need a professional roofer to clean and protect your roof.  The following guidelines will help you keep your roof in good condition so that major problems do not arise.

• ·         Have your roof inspected at least twice a year for signs of damage.  Professionals recommend roof inspections at the end of winter and beginning of fall as the fall and winter months generally bring the most damaging weather with respect to roofs.
• ·         External roof inspections are important, but also look for signs of damage internally.  Search every room and your attic for water spots on the ceilings and walls.  Make sure to check in closets and storage spaces and even look behind furniture.  Water spots and mold are indications that your roof may have a leak.  You’ll need to find the source of any water spot to avoid dry rot, mold, and even pest infestation.
• ·         In your attic, check beams and rafters for signs of water damage.  Mark water spots so you can easily determine if they are growing – a sure sign of a roof leak.
• ·         External roof inspections should focus on the overall quality of the roof as well as closer inspections of roofing materials and fixtures.  A professional roofer will assess the condition of your roof’s major features being careful to spot moss or algae growth.  They’ll check the flashing and eaves, as well as gutters to ensure they are draining properly.  If they notice parts of your roof sagging, this is an indication of more serious structural damage, and your roofing contractor will recommend the necessary repairs.
• ·         Hire a roofing professional to take a walk on your roof for a more refined inspection of fixtures and materials.  If they spot missing shingles or damaged flashing around chimneys and other fixtures, your roofer will need to conduct some repairs.
• ·         Always consult a professional roofer when you are not confident in your abilities.  Roofing repairs and installation require specialized skills, tools, and safety equipment that you likely do not own.  Nevertheless, maintaining the condition of your roof is crucial to protecting your home and belongings.

The leaky condo crisis of the 1980s, 1990s, and early 2000s provides plenty of proof that construction materials and methods can have a major impact on the overall condition and quality of your home.  Living in British Columbia means that you likely experience more rain in a few months than most climates experience in an entire year.  Yet, if you’re wondering which the best roofing materials for British Columbia are, there are no simple answers.  Indeed, British Columbia offers a very diverse climate, and many regions face a great deal of rain as well.  So, if you’re asking yourself which roofing materials are the best, speak to a qualified roofing contractor in your city.

Nevertheless, while even the most experienced roofer cannot offer a simple answer to this question, there are some guidelines that can help you choose the best materials for your roof.  Today, residential roofing materials come in a wide range of colours, textures, and types that each offer unique benefits and characteristics.  Choosing the right roofing material for you requires that you carefully consider your needs and also discuss your options with a roofing contractor.

Clearly, your roof is an important aspect of your home; one that provides key structural elements in addition to protecting your home, its contents, and your family from inclement weather.  Moreover, roof replacements generally constitute a sizeable investment, but if you choose the right roof and the right materials, it is an investment for many years to come.  Your roof should not only provide the right function, but the right style as well so choosing the right roofing materials requires that you make the following considerations:

1. What is your budget?  An excellent roofer can help you choose sound materials and design that will fall within your budget.
2. What is the style of your home?  Roofing materials are available in an impressive variety of styles, colours, and textures so be sure to choose materials that match the look of your home.
3. What are your insulation needs?  Your roof needs to effectively insulate against cold winters and hot summers.
4. Will your roof resist fire?  This is an important consideration for all homeowners, but especially those who live in high risk forest fire zones.
5. What are your weather conditions?  Rain, snow, and wind are just a few elements that can have a destructive impact on your home, so you need to consider these factors before choosing a roof.

Still, even after you consider all these questions, you will still find a variety of options available to you.  Composition or fibreglass shingles, wood shakes, rubber shakes, clay tile and slate roofing, and even metal roofing are all popular options in British Columbia.  As such, you should make an appointment with a professional roofer to determine the style, function and design of your roof and which materials fit best.

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.

Roof maintenance is important, no matter the cost.  As one of the most structurally significant aspects of your home, keeping your roof in tip top condition also helps you protect your home and your belongings.  Indeed, a quality roof does more than just keep the rain out.  The structural integrity of your roof is important for insulation too.  In other words, your roof keeps your home dry and warm!  So, if you’ve discovered a leak and a professional roofer is recommending repairs, follow their advice – the costs associated with roof repair are usually a fraction of the cost of replacement.

Repair costs can vary significantly.  The most basic repairs may be as little as $100 to $200, while the most advanced repairs could exceed $2000.  On average, roofing repairs land somewhere in the middle, usually between $400 and $800.  While these costs certainly seem expensive, you need to consider the importance of your roof as well as the cost of replacement (which can easily exceed $5000 depending on the type and style of your roof). 

Types of Repairs

Among the most common roofing repairs relate to shingles.  During storms, it’s not uncommon for shingles to be broken or even blown off completely, particularly on older roofs.  In fact, even on newer roofs shingles can be lifted off during high winds.  Heavier shingles stand up better to high winds, but no material is entirely weatherproof.

Another common roofing repair relates to flashing.  Flashing is the material that surrounds vents or other roofing fixtures, and while they are sealed to your roof flashing is usually made from metal material and prone to corrosion over time.  This includes flashing around chimneys and skylights which can pose a significant risk to leaks.

Roof valleys are another part of the roof that commonly requires repair due to water build-up on the interior angles of your roof.  A great deal of water flows down roof valleys making these roof areas more susceptible to damage over time.

If you live in a cold climate, ice dams pose another significant problem.  When accumulated snow on your roof melts and then re-freezes, ice dams form.  This can prevent normal drainage from your roof and eventually causes leaks.

Professional Repairs

Unless you are a roofing professional yourself, you should always hire an expert roofer for repairs.  While you can often see signs of a leak inside your home, it can be difficult to trace the original source of the leak on your roof.  In addition, professional roofers have the expertise to identify potential future roofing problems so they can conduct preventative repairs that are generally less costly.  For this reason, you should also have your roof professionally inspected every year.
