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).

If the time has come for you to repair or replace your residential roof, it’s also time to learn something about the most common materials used in residential roofing.  Depending on your geographic region, the materials currently used in your roof, and your budget, your choice of roofing materials is going to vary.  In Canada, there are several commonly utilized residential roofing materials including asphalt, clay, concrete, and metal.  Let’s take a moment to describe and compare each of these materials.

Asphalt Shingles

Sometimes referred to as composition shingles, asphalt shingles are probably the most common residential roofing material in the world.  They are affordable, lightweight, easily installed and maintained, and they are available in a wide range of colours and styles.  Typically, asphalt shingles represent a durable roofing material, particularly when you consider their cost.  Still, their lightweight nature means they are easily damaged by wind.  Moreover, their popularity means they are produced by a large number of manufacturers so you want to take care to choose a company that produces quality shingles.

As an alternative to asphalt shingles, laminated shingles are very similar but provide better protection in windy environments and they even offer better fire protection.  Also, whereas asphalt shingles have a lifespan of 20 to 25 years, laminated shingles can last up to 50 years.

Clay

Although among the most expensive residential roofing materials (ranging from $10 to $30 per square foot), clay tiles offer superior durability and can last up to 100 years in the right climate.  That being said, these residential roofing materials are very heavy, so your home must be able to provide the adequate structural support.  Additionally, clay tile are not suitable for colder environments as they can crack when temperatures cause them to freeze and thaw.  Still, they stand up well to strong winds and fire, and they are available in a beautiful array of colours.

Concrete

Concrete tiles are a more affordable alternative that have similar properties and appearance to clay tiles.  However, concrete tiles are more versatile with respect to styles and they are even manufactured to look like wood.  Another strength of concrete tiles is that they withstand freezing temperatures better than clay, and they offer incredibly durability with lifespans of up to 50 years.  Unlike other residential roofing materials, concrete tiles tend to absorb a lot of water and may develop mildew so they are not ideal for rainy climates.

Metal

Metal roofs are lightweight and durable and provide superior fire protection.  For environmentally-aware homeowners, metal roofs may be constructed from recycled materials and can be installed over your existing roof to reduce the waste associated with roof replacement.  A somewhat expensive material, costs are balanced with longevity as metal roofs tend to last between 50 and 70 years.  Nevertheless, metal roofs are difficult to repair and they are not suitable to all climates.

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.

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.

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.

Sustainability matters.  As cities grow and societies become more complex, the impact of human life on the environment is becoming frighteningly clear – we’re creating climate change which has devastating consequences for all life on earth.  To this end, new building practices that focus on sustainability are setting the trend for future development.  Green roofing is one building practice that has a variety of environmental benefits.

Green roofing is suitable for almost any type of building – large or small.  Residential homes, apartments and condos, industrial facilities, and parking garages can all be constructed with green roofing.  Nevertheless, let’s focus on some of the applications and benefits of green roofing for commercial building.

First, let’s talk money – after all, commercial enterprises exist to make money.  Fortunately, green roofing not only addresses many of the livability issues arising in urban centres, it also enhances the performance and appearance of commercial properties while reducing many costs.  Without a doubt, green roofs will save money over the long term.  Even if we just consider heating and cooling costs, green roofs will essentially pay for themselves by reducing these costs. 

Moreover, green roofs increase a building’s resale value while also giving the building a competitive advantage when it comes to finding tenants.  Indeed, commercial properties featuring green roofs attract potential tenants not only because of reduced energy costs but also because these buildings are more interesting and attractive.

Still, the main reasons to consider green roofs for your commercial project are the livability issues that dense, urban population has created.  The heat-island effect, storm water mitigation, and biodiversity and habitat issues are major concerns that need to be addressed and green roofing may be the answer.  Let’s take a closer look.

The heat-island effect refers to the increased use of concrete and glass in urban construction that has resulted in increased temperatures in dense urban areas.  Average urban temperatures regularly exceed those of surrounding rural or suburban areas simply due to a lack of vegetation in the city.  Green roofs ameliorate this heat-island effect by providing shade and removing heat from the air.

Another urban problem resulting from the use of concrete and asphalt in construction relates to storm water mitigation.  During rain storms, demands on storm water infrastructure are considerable and flash floods can result.  Green roofs help urban centres manage storm water as they act as sponges to capture or slow the movement of storm water. 

Finally, commercial roofing projects that feature green roofs can help improve biodiversity by replacing habitats for insects and birds.  Green roofs certainly make buildings more physically attractive, but they can also contribute to creating a healthy environment that promotes a healthy food supply.

Ultimately, there are many excellent reasons to invest in green roofing for commercial buildings, and the cost of these roofs needn’t be prohibitive especially when you consider the many benefits these roofs bring.

Are you worried about your roof?  You probably should be.  Ok, maybe you needn’t worry, but you shouldn’t ignore it either.  Your roof is arguably the most structurally important feature of your home.  It’s not only what ultimately provides you shelter, but it is also responsible for much of your home’s structural integrity.  A well-maintained roof is one that protects your family and belongings from all kinds of inclement weather.  So, how often should you inspect your roof?

Daily exposure to the elements – sun, rain, wind, and snow – will take its toll on even the most advanced roofing system.  Most roofs are expected to last a maximum of 25 to 30 years, and to get the most from your roofing warranty, regular maintenance is a necessity.  Indeed, regular inspections allow for regular maintenance which will ultimately extend the life of your roof.  Without proper maintenance, some roofs will lose half or more of their lifespan; so even though there is a cost associated with professional inspection and repair, keeping on top of roof maintenance will actually save you money in the long run.

More importantly, many roof warranties stipulate that regular maintenance is required or the warranty is voided.  This applies to both commercial and residential roofing systems, so whether you’re a home owner or a business owner, you want to take roof maintenance seriously.  Typically, roofing professionals will tell you that twice annual inspections are the way to go.  This is especially true in climates where there are distinct seasons, particularly if you’re in an area that gets harsh winters. 

So then, when should you have your roof inspected?  In a perfect world, you want to bookend your inspections around the season with the most severe weather – typically winter.  Why?  It’s simple.  You want to make sure that your roof is ready to withstand all that Mother Nature has to offer before that season starts.  And when that season is finished, you want to be sure that your roof has survived without sustaining significant damage.  Plus, as a side-benefit, discovering roofing damage in the off-season (when roofers are least busy) means you can conduct repairs at a much more affordable rate.  On the other hand, if you wait until winter and you discover significant leaks in your roof, repairs will be significantly more costly.

Finally, a quick note on who should conduct inspections is warranted.  It is always advisable to work with a professional roofer for inspections.  Not only do they have the skills and expertise to thoroughly assess your roof for damage, they also have the required equipment to do the job efficiently and safely.  Remember, the modest cost of regular maintenance will most definitely save you when it comes to replacement and repair in the future.
