Asphalt Shingle Roof

Roof replacement is never a priority to most homeowners, and understandably so. Since it does not bring the same return on investment as bathroom or kitchen renovations, most people don’t prioritize it. However, changing the roof when it nears or reaches its lifespan is a smart move that can save you a lot of money. It can also increase the property value and make selling the property simpler. Immediate replacement or facia repair is also essential if there is significant damage to the roof.

Below, we explore the cost of a roof replacement and the different types of roofs you can consider to help you make an informed decision.

Is Replacing Flat Roof Cheaper Than Pitched Roof?

Pitched roof replacement involves a more complicated process than flat roofs. The slope makes the roofs more dangerous, but several other factors influence the cost. They include:

  • The inclination depth.
  • Roofing materials.
  • Architectural design and how complicated it is.
  • The size of the roof.
  • Warranties attached to the roof.
  • The type of service provider and their labour charges.
  • Any necessary extra work like upgrading the ventilation.

Cost To Replace Pitched Roof

Pitched roof replacement cost varies with every property. Multiple factors are involved in the substitution process. They include the disposition of the roof, the material that needs replacement and its lifespan, and the location. Pitched roofs on a double-story house are more expensive than those on a single story. Changing a roof with multiple slopes is also more challenging, making it costlier. Some roofing materials are more difficult to handle because of their weight, nature, or intricacy, leading to cost differences. You are likely to spend between $10000 and $53000 to replace a pitched roof on a double-story building. The cost of a roof with multiple slopes ranges from $12000 to $80000.

Cost To Install Asphalt Shingle Roof

Asphalt shingles are the cheapest roofing materials, making them a favourite among many homeowners. They also have other advantages, such as a significant lifespan and versatility. They have different colours, shapes, and sizes. With asphalt shingles, you can customize the roof to get any design you prefer. Asphalt shingles are also durable and sturdy enough to resist impact from high winds, falling tree branches, or hailstorms. They are also resistant to fire but are susceptible to cracking or drying out as they near their lifespan.

The roofing materials are valuable additions to any property. They have excellent soundproof qualities and are easy to use, making them perfect for people who prefer the DIY approach.

Asphalt roofing shingles prices differ in every location but are considered the cheapest compared to other roofing options. Various roofing companies charge different amounts. In Toronto, you can expect to spend approximately $7.5 on every square foot. The prices also depend on the type of roof and how complicated the design is. For instance, replacing a single-storey house can cost approximately $7500, while a double-storey can be $10000. If your property has a complex architectural roof design, you will spend at least $12000. Since the longevity of asphalt is an average of 20 years, the material offers good value for money.

Discuss the prices with the roofing contractor and get an accurate quote so you can budget accordingly.

Advantages and Disadvantages of Asphalt Shingle Roof

The main advantage of asphalt shingles is their affordable price. That, and their ease of installation, makes them a favourite among many property owners. People who have knowledge or experience with roofing processes can install them easily.

The shingles are also versatile materials that allow homeowners to try out various design options. They are available in different colours and finishes for simple customization. They can appear like other materials such as wood, tile, or slate.

Asphalt shingles can last between 15 and 25 years. However, most people replace them after 20 years.

Disadvantages

Compared to other roofing options, asphalt has less longevity. That makes them less suitable for people who need lasting roofing solutions.

The shingles may lose their original colour over time, reducing the aesthetic appeal. They are also vulnerable to cracking and loosening the longer they remain exposed to the natural weather elements. Additionally, repair costs may be higher than other roofing materials.

Since asphalt is a petroleum-based material that is not recyclable, it is less friendly to the environment. Its manufacturing process also uses more energy. It usually produces methane gas when disposed of in landfills.

Different Types of Asphalt Roofs

FIBERGLASS SHINGLES ROOF

ORGANIC SHINGLESS ROOF

Fiberglass shingles are the most popular type. Although they have different layers, they are portable and easy to use. They consist of woven fiberglass mat, asphalt, and ceramic granules on the top layer. The granules protect the roof from damage by ultraviolet rays. Their lightweight nature eliminates the need for reinforcement of trusses and rafters, reducing the workload during installation. They also have higher resistance to fire than other asphalt materials. Most roofing manufacturers also make fiberglass shingles with extended warranties.Although they are known as organic, they contain more asphalt than fiberglass. Organic shingles are more detrimental to the environment. They contain recycled felt paper with asphalt, with another asphalt adhesive and ceramic granules on top. The extra asphalt they contain makes them heavier and thicker. They have a higher absorption rate, are more expensive, and are more vulnerable to warping. As such, you are likely to spend more money repairing them than you would with fiberglass.

 

ASPHALT SHINGLE ROOF STYLES

THREE-TAB SHINGLESThese shingles look like three different pieces because of the multiple tabs on their lower edges. They are the most affordable asphalt shingles type. The low cost is the main reason why they are the most preferable for homeowners.
ARCHITECTURAL SHINGLESSArchitectural shingle types have a distinguished appearance that comes from the additional asphalt used to laminate them. They do not have cutouts, giving them a unique appearance. They are more attractive and can create more distinctive shapes on the roof. That is their main advantage over three-tab shingles that have limited design options.

How Much Does a Metal Roof Cost?

Metal Roof

Metal roofs have their fair share of advantages and disadvantages. The most common demerits are fading, high prices, and high noise levels. The merits include longevity of up to 70 years, the ability to withstand strong winds and other natural elements, and corrosion resistance. They also require minimal maintenance and do not crack easily.

Metal roofs are also the most eco-friendly materials available. They are made with recycled materials, and the old roof is also recyclable in case of a replacement. Their reflective nature also helps with heat reduction in the house, reducing cooling costs by up to 25%.

Metal roof cost typically ranges between $21 and $36 per sq. ft. The more complicated the roof design is, the higher the cost. The cost of a metal roof in Ontario ranges between $21500 and $36000 for a single-storey house. The price of two storeys is from $23000 to $45000. Luxury homes can cost a minimum of $29000 and a maximum of $80000.

METAL ROOFINGCOST PER SQ. FT.LIFESPAN
Single storey$20.5K – $36K
Double storey$23K – $45K$21 – $36/sq. ft.50+ years
Luxury home (multiply slopes)$29K – $80K

Advantages and Disadvantages of Metal Roofs

  • High-efficiency

Metal roofs can reduce energy consumption in the house by reducing heating and cooling needs. They are also made with eco-friendly materials, helping with eligibility criteria for tax credits.

  • Longevity

Metal can last up to four times longer than asphalt shingles. You get at least 50 years.

  • Minimal maintenance

They are less vulnerable to peeling and can withstand all the natural elements. They need minimal repairs during their lifespan.

  • Simpler installation

You can place them over other types of roofing materials like asphalt.

  • Higher value

The durability and resilience of metal roofs make them very valuable.

  • Portability

The weight of metal roofs is almost half that of asphalt, meaning they cause less stress on trusses and rafters.

Disadvantages

  • Higher costs

The cost of purchasing metal roofs is higher than that of asphalt shingles. However, they are long-lasting and do not require frequent repairs, offsetting some of the long-term costs.

  • Difficult repairs

Finding a metal roof that matches yours is challenging in case a small roof section gets damaged and needs replacement.

  • Loud

The sound of rainfall on the roof may be too much when you have a metal roof. Insulation is essential.

  • Expansion and contraction

The metal sheets need proper fastening to allow contraction and expansion with weather changes.

  • Not suitable for emergencies

If there is an emergency like a fire outbreak, responders will find cutting the metal to access the house more challenging.

Different Types of Metal Roofs

  • FIBERGLASS SHINGLES

Fiberglass shingles are very portable materials. Manufacturers make them using woven fiberglass mats with asphalt and ceramic granules on top. They are thin and easy to use, making them more ideal for DIY installers. The shingles also have a better fire rating, resistance to UV rays damage, and better warranties. Using fiberglass is also easier because they do not strain the trusses and rafters. You do not have to add extra support to the roofing structures before installing the shingles. All these benefits make them the most sought-after asphalt shingles.

  • ALUMINUM

The flexibility of aluminum is its main advantage. It can be formed into various shapes to create different patterns or distinguished looks on every roof. The material is also reflective and recyclable. It reduces the need for heating and cooling in the house and does not end up as harmful waste, making it better for the environment.

  • COOPER

The most noticeable benefit of copper roofing is durability. The material can last very long with minimal susceptibility to corrosion.

  • ZINC

Zinc has self-healing properties – a coating naturally forms on it as it ages. It can also cover scratches that form on it, making it highly resilient. It does not require as many repairs as other materials.

  • STAINLESS STEEL

Stainless steel is the most used metal roof type by property owners. Its main benefit is resistance to rust and corrosion. It also has a high moisture resistance capacity and enhanced visual appeal.

  • TIN

Tin is the cheapest material out of all metal roofing types. Apart from the cost, tin is also flexible and resistant to corrosion. It can be formed into different shapes on the roof.

COMMON METAL ROOFS STYLES

THREE-TAB SHINGLESThree-tab shingles often look like they are three different pieces instead of one single piece. The tabs on their lower edges give them that appearance. They are also the cheapest metal roof styles and the most favourable to most people.
ARCHITECTURAL SHINGLESSThese roof styles do not have cutouts. Instead, they have asphalt laminations that make them look wholesome. They have a superior aesthetic appeal and can be used to form unconventional shapes on roofs. They do not limit styling options the way three-tab shingles do.

What is the Cost of Slate Roofing?

Slate Roofing

Slate roofing adds an unmatched curb appeal to any property. The material comes from natural stone, which means it retains its original colour throughout its lifespan. Slate roofing also has practical qualities that make it perfect for buildings. It is less dangerous to the environment, adds insulation to the house, and is fireproof. It also has the most extensive lifespan. Regular maintenance can get you a roof that remains in good condition for up to 150 years.

Natural stone is typically heavy and pricey, making those the main disadvantages of slate roofing. The extra weight also means the roof structures will need reinforcements before slate roofing is installed. Because of these drawbacks, slate is the least popular roofing option. Many roofing contractors do not have experience dealing with slate, meaning you are less likely to find quality services if you choose the material.

Slate roof replacement cost ranges between $30 to $42 per square foot – at least $27000 for a single storey, $34000 for a double-storey, and $43000 for a luxury home.

SLATE ROOFINGCOST PER SQ. FT.LIFESPAN
Single storey$27K – $47K
Double storey$34K – $53K$30 – $42/sq. ft.75 to 150 years
Luxury home (multiply slopes)$43K – $72K

Advantages and Disadvantages of Slate Roofs

Pros

  • Long-lasting

Slate roofs can last at least 100 years and longer (up to 150 years) with proper installation and maintenance.

  • Visual appeal

Slate is an elegant material that gives roofs a classic appearance. The material is also available in various sizes, colours, and thicknesses that provide more design choices for homeowners. You can choose from green, red, purple, black, or mottled tiles to create any roofing style you prefer.

  • Eco-friendliness

Roofing waste makes up to 5% of all the waste deposited in landfills in different parts of the country each year. Since slate can last at least a century before replacement, it does not account for the majority of the waste.

  • Fireproof

Slate is not just fire resistant – it is fireproof. You do not have to worry about wildfires or fireworks causing extensive damage to your house.

Cons

  • Excess weight

Slate weighs between 800 and 1500 pounds per 100 square feet. Therefore, gauging the structural integrity of the house before installing the slate is mandatory.

  • Requires extensive skills

Most contractors lack the knowledge or skills to deal with slate. Finding the right one to work on the roof can be difficult. Remember, a poorly installed slate roof does not last.

  • Fragility

Slate is a delicate material that can break easily with the slightest pressure. That means you cannot walk on the roof, even if the air conditioning needs repair. Replacing broken tiles is not easy either because the material is sold in batches. Finding perfectly matching tiles may be impossible.

Different Types of Slate Roofing

NATURAL SLATE ROOFFIBER CEMENT SLATE ROOFBITUMINOUS SLATE ROOF

Most people are familiar with natural quarried slate because of its impressive lifespan. The roofing material comes with an outstanding ability to adjust to the contraction and expansion caused by temperature fluctuations. It is also resistant to damage by UV rays.

The roofing material is also one of the safest options for the environment. The quarrying process means its manufacturing process does not emit a lot of carbon footprint to the surrounding. The longevity means it does not contribute to the waste in landfills like other materials such as asphalt. It is also possible to reuse old material.

The slate roofing style is available in many hues, and a good contractor can use them to create any pattern you like on the roof.

Fiber cement slate roof is the second most commonly sought-after roof type. Most people chose it because it is cheaper than natural slate and is available in different colours. Unlike natural stone slate, the colors in fiber cement are factory-applied. They also have more customized shapes, including diamonds. Their lightweight nature means they can remain steady and function without reinforcements on the roof. That makes their installation less labour-intensive.

On the downside, fiber cement slate roof does not have a very long lifespan. However, it can last up to 70 years, which is still better than what other roofing materials have.

Bituminous slate is similar to shingles because of the bitumen or asphalt component. Their installation procedures, maintenance requirements, and lifespans are alike. That means it is easy to work with, can last at least 20 years, and requires regular maintenance.

The main difference between the two is in the texture. Asphalt shingles are usually rough like sandpaper, but a bituminous slate is smooth like a natural slate.

The main advantage of a bituminous slate is flexibility. It can work on dome-shaped roofs or eyebrow windows. It also has high tensile strength, meaning it is less likely to crack, unlike asphalt.

Slate Roof Styles To Choose From

  • STANDARD UNIFORM ROOF

The most common slate roof style is the standard uniform roof. It is made with slates that have a thickness ranging from 1/4 inch to 3/8 inches and standard widths and thicknesses. The slates also

have square cut butts. As the name suggests, the installation process is straightforward because the tiles are laid consistently ‘on the roof. The tiles are placed uniformly, and the spacing is also uniform. Installers use an offset pattern with the vertical joints alternating.

  • PATTERNED ROOF

If you want a more colourful roof, patterned slate tiles are the perfect solution. Such tiles enhance creativity and can produce a roof pattern that stands out from all others. The designs can differ, with some being geometric shapes and others being tiles with different shapes placed in strategic locations on the roof. The numerous design options are some of the main benefits of slate patterned roofing style. You can try out any idea you like with the help of a contractor.

  • GRADUATED AND TAPERED ROOF

Other roofing materials do not usually work for dome-shaped roof designs or those with round towers. Such roofs require specially designed slate tiles, and that is where graduated and tapered style comes in. Every siate tile is styled to suit a specific spot on the roof. For instance, you can have scallop-shaped tiles in different sizes for various sections of the roof surface.

  • BLENDED SLATE ROOF

Slate is available in different colours ranging from grey to purple. Mixing those tiles and their colours creates a blended slate roof. You can use standard colours like a mixture of browns, greens, reds, and purple or get customized colour combinations. Either way, the style is one of the unique options to try.

  • TEXTURAL SLATE ROOF

Natural slate is non-uniform roofing material. It is available in different sizes, shapes, widths, and thicknesses. Using it on a roof results in a textured appearance. You are likely to see chipped corners and uneven edges on properties with this slate style.

  • HANG-DOWN STAGGERED ROOF

Hang down staggered style is created with tiles that have varying sizes. The different lengths and widths of every tile can give you an outstanding design. They also make it easier to get imaginative with the layout to get distinguished patterns.

Cost To Replace Flat Roof

What is The Cost of TPO/EPDM roofing materials?

TPO-EPDM

Thermoplastic Polyolefin or TPO and Ethylene Propylene Diene Monomer (EPDM) are both rubber compounds, but they have some features that differentiate them. For instance, TPO has a more neutral colour and is cheaper – it is usually available in white. Its installation process is uncomplicated because it involves the use of adhesives or screws. EPDM has a darker colour that is easier to notice. The most common one is black EPDM, which is also the most recommended. White is also available, though most people do not like it. Despite their similarities, EPDM is superior to TPO. It can withstand most natural elements, including rain, temperature changes, ultraviolet rays, and snow. It is also resistant to damage by abrasions. The sheets are usually bigger, making installation simpler.

EPDM and TPO have the same longevity as asphalt shingles. Replacement becomes essential after approximately 20 to 30 years. Expect to spend at least $11 per square foot when you buy either material. If you own a duplex property, you will not spend more than $15000 replacing them. A triplex property will cost a maximum of $19000, while a 6-plex building costs at least $48000. The prices will differ depending on the labour cost and other factors influencing the replacement.

 

TPO/EPDMCOST PER SQ. FT.LIFESPAN
Duplex$11K – $15K
Triplex$14.5K – $19K$11K – $15/sq. ft.25 to 30 years
6-plex$48K – $60K

Difference Between TPO and EPDM Roofing

EPDM has been a popular choice in the roofing industry for a very long time, but TPO seems to be taking over as a favourite roofing material for many commercial property owners. EPDM is a suitable option for buildings in areas that experience frequent hailstorms. The synthetic rubber system keeps moisture and other weather elements from reaching the interior roofing structures. With TPO, hailstorms can create a lasting impact by forming circles on the thermoplastic surface. With time they can compromise the roof system.

Repairing damages on a roof with EPDM is also more effortless than it is with TPO. The roofing materials do not require the use of electric equipment. Since it is also less reflective naturally, solar panels placed on the roof can absorb sunlight without any interference. TPO is more reflective, which can influence the performance of solar panels.

TPO roofs have lighter colours that help with energy efficiency. On the other hand, EPDM has darker surfaces and can absorb more heat during summer, leading to more energy consumption for cooling.

TPO is also more resistant to impact than EPDM. It offers three times better protection. However, TPO installation is more complicated because it involves welding. That process enhances its durability but consumes more time and is more labour-intensive. It also makes repairs more difficult to handle.

How much is an elastomeric membrane roof?

elastomeric membrane roof

While other roofing materials require installation during specific times of the year, the elastomeric membrane does not. That is one of the reasons why many Canadians prefer it over others. Its double layers enhance its durability, and the minimal maintenance makes it a valuable investment. It can last up to 30 years.

However, elastomeric does not have fire-resting properties. Therefore, only highly specialized contractors should handle it to avoid a fire hazard. The material cannot be recycled either, making it a threat to the environment.

The price of an elastomeric membrane does not exceed $25 per sq. ft. That means if you have a 6-plex, you will need at most $114000 and at least $96000 to get a new one. A duplex and triplex will require at least $20000 and $31000 each.

ELASTOMERIC

Duplex$20K – $25K
Triplex$31K – $37K$19 – $25/sq. ft.20 to 30 years
6-plex$96K – $114K

Advantages and Disadvantages of Elastomeric Membrane Roof

Advantages

  • Moisture resistance:Elastomeric has double layers that make it more waterproof.
  • Significant longevity:With proper installation, the roof can last approximately 30 years.
  • Attraction:Elastomeric makes the roof appear more polished and cleaner. It is available in white and black, which are likely to blend in with any home style.
  • Robustness:The material can withstand harsh weather conditions, whether it is strong winds or heavy rain.
  • Straightforward installation:Property owners do not have to wait for specific seasons to install the material.
  • Good ROI:Its durability makes it a good roofing choice worth the investment.
  • Maintenance:Elastomeric does not require frequent servicing, but regular inspections can prolong its lifespan.

Disadvantages

  • Safety: A blowtorch is necessary for the proper installation of elastomeric, especially the traditional ones. It requires specialists’ installation to avoid fire hazards.
  • High price: The cost of elastomeric is slightly higher, considering the features and benefits it has.

DIFFERENT ELASTOMERIC MEMBRANE ROOF TYPES

Traditional elastomeric
membranes roof
Traditional elastomeric membranes roof uses modified bitumen membrane with a finishing membrane that has coloured granules. The membrane is usually black or white to protect the roof from excess heat. The two layers are fused with a blowtorch, just like the installation.
Self-adhesive elastomeric
membranes roof
A self-adhesive elastomeric membranes roof does not require the use of a blowtorch. It uses the cold-install technology that makes it a safer option. You do not have to worry about a fire breakout during installation or the smell of hot asphalt.

Cost Of Multi-layer Roofing (Gravel & Bitumen)

Multi-layer Roofing

Bitumen is an improved version of asphalt, but the material does not aid down like asphalt. Instead, it is painted on the roof to get a seamless roof that does not leak. The material does not split or get damaged easily either because of its tensile strength.

When it comes to disadvantages, bitumen absorbs too much heat. That can make the rooms below uncomfortable, leading to the air conditioning systems consuming too much energy to maintain a comfortable temperature. In addition, the cost of gravel and bitumen does not match the value. However, property owners get to choose from the available choices. 1-ply bitumen is a cheaper option, but it is not as durable as 2-ply or 3-ply that are more expensive.

BITUMEN ROOFINGCOST PER SQ. FT.LIFESPAN
Duplex$11K- $15K
Triplex$18K – $25K$11 – $15/sq. ft.15 to 30 years
6-plex$30K

Advantages of Multi-ply Roofing

Advantages of Multi-ply Roofing

  • Better tensile strength– Bitumen is tougher than asphalt and can withstand pressure for longer. Regular maintenance or repairs will not be necessary.
  • Multiple plies are available– Single ply bitumen is not very strong, but two or three layers with polymer compound do not get punctured easily. Their thickness can be up to 300 mm.
  • Different roofing options– Multi-ply roofing can be applied the same way as hot asphalt. However, heat welding and cold adhesive are viable options, especially if the former method is unsafe.
  • Maintenance – The durability of bitumen, especially the multi-ply ones, reduces the need for regular maintenance. Conducting repairs in case of a problem is also easy.

How Much Does the Green Roof Cost?

Green Roof

Green roofs are increasingly becoming popular in different parts of the world for various reasons. One, they provide a habitat for insects and birds, increasing biodiversity. Second, they also reduce energy costs by providing insulation and decreasing stormwater runoff.

Green roofs are available in two types – intensive and extensive. The former calls for cultivation and is more similar to farm gardens, while the latter only serves as a recreational space without cultivation.

Both green roof types have their disadvantages that are worth considering before installing them. First, they cost a lot of money to put in place and require frequent maintenance to remain in good condition. They do not work on sloped roofs – the angle must be less than 25 degrees. Some studies are underway to determine if green roofs can thrive at 45-degree angles. Finally, the green roof requires a different soil type because regular ground soil does not work. Your garden soil is also likely to kill the plants.

GREEN ROOF
Duplex$25K – $50K
Triplex$40K – $78K
6-plex$120K – $240K
