Your roof carries a lot of responsibility. Its job is to protect your home and everything inside. Bad roofing materials can quickly damage the walls, siding, insulation, and wreak havoc on your foundation.
The roofing materials you choose are a major source of insulation that keeps you warm in the winter and cool in the summer.
Whether your home is a brand-new craftsman or a 100-year-old farmhouse, if you want to protect your home, you must start with choosing the right materials for your roof.
What’s Better for Residential vs Commercial Roofs?
There are two overarching types of roofing: residential and commercial.
Residential Roofing: Drive through your neighborhood you’ll likely see a variety of different roof types, but only if you pay attention. Roofs don’t usually draw a lot of attention.
Most residential roofs appear to be a simple covering of shingles or tiles. However, the components and structure of residential roofing are much more complex than most people think.
Commercial Roofing: Commercial roofing tends to have a low slope or maybe entirely flat. Because a commercial building is typically much larger than a residential roof, the materials and installation methods used are often different.
Types of Roofing Materials
Within both residential and commercial roofing, there are several roofing materials to choose from. Each roofing material has unique characteristics, advantages, and disadvantages.
1. Asphalt Shingles
Asphalt is one of the most commonly used residential roofing materials. Shingles are popular for good reason. they are affordable, easy to install, and can be repaired without replacing the entire roof.
Asphalt Shingle Styles
- 3-tab shingles: This is one large piece of material that looks like three separate shingles. It is a very popular shingle style and the most budget-friendly choice.
- Architectural shingles: Architectural shingles use multiple layers of material to actually create a dimensional look laid piece by piece.
- Luxury shingles: If you’re looking to add more visual interest to your roof, these shingles often imitate the look of wood shakes or clay tiles.
Pros and Cons
- Pros: Asphalt comes in a variety of colors, is widely available, easy to install, and is one of the least expensive materials.
- Cons: Overall, asphalt has a shorter life span than other roofing materials and can be damaged from hail and strong winds.
The low-end cost of an asphalt shingle roof is about $4/square foot. This is with builders-grade shingles, no penetrations or valleys, and a one-story home.
The higher-end costs land about $7 per square foot. This would be for a two-story house, a complex roof, and luxury shingles.
If maintained properly, asphalt shingles can last between 20-30 years. However, this is the exception and not necessarily the rule.
Particularly high heat and storm damage often require replacement closer to 10-15 years.
Asphalt shingles are ideal for cool weather areas because they draw in heat. They are fine for humid and cold regions of the county as long as they are treated with algaecides.
2. Wood Shingles and Shakes
Wood shingles or shakes add a naturally beautiful touch to any roof and last longer than asphalt shingles. However, they are high maintenance and can be a fire hazard.
Different Types of Grains in Wood Shakes and Shingles
- Edge Grain: This is the highest quality wood shingle roofing material that is cut perpendicular to the tree rings giving it more durability and strength.
- Flat Grain: Cut parallel to the ring, these are cheaper but also more likely to split over time.
- Slash Grain: When the piece is cut at an angle to the tree’s rings and is the cheapest and least desirable.
Pros and Cons
- Pros: Wood gives a beautiful authentic look that can’t be replicated. Additionally, wood can provide twice the insulation as asphalt shingles.
- Cons: Wood requires more maintenance and can be prone to molding, splitting, or rotting. In some areas, fire codes actually prohibit the use of wood shingles.
The cost can range between $6 and $10 per square foot, mostly depending on the cut and the type of wood.
Cedar shingles can last over 30 years, but they must be installed correctly and maintained correctly whenever they are exposed to rain or snow.
Wood shingles are best used in colder areas that don’t experience a lot of fire danger or humidity in the summer.
3. Slate Shingles
Natural slate roofing shingles are made from real rock and stone. They are extremely durable and can last for over 100 years.
Types of slate roofs
- Standard uniform slate roof: This is the most common, where all tiles are cut the same length and width.
- Patterned slate roof: There are various roofing materials to design and create a pattern on slate roofs that is a focal point of the home.
- Hang-down staggered slate roof: This is a very rough, authentic look with various colors, textures, and widths of slates with rough bottoms creating a rugged appearance.
- Textural slate roof: Similar to the hang-down, but more rustic and uneven with overlapping sections and different sizes and thicknesses throughout.
- Graduated length slate roof: This is a detailed pattern where the eaves of the roof hold larger slates and the thinner slates are placed on top.
Pros and Cons
- Pros: Slate is naturally impervious to moisture, insects, fire, and weather. It is also eco-friendly.
- Cons: Slate is expensive and heavy. Therefore, it requires extra fortified framing and professional installation.
Slate is more expensive than other materials, starting at $9 per square foot, ranging up to over $15 per square foot depending on the quality of materials and labor costs.
Slate will last a lifetime, even multiple lifetimes. Hard slate will last anywhere from 75 to 200 years, the soft slate will last between 50 to 125 years.
Sturdy homes. The home has to be built to withstand the weight of slate. Because of its durability, slate can be used anywhere.
4. Metal Roofing
Metal roofing materials have recently spiked in popularity throughout residential neighborhoods due to their durability, longevity, and unique style.
Types of Metal Roofing
There are several different types of metal roofing using a variety of metal materials.
- Steel Roofing: Most standing seam metal roofing falls in this category and is an alloy of iron and other elements.
- Aluminum Roofing: Lightweight and strong metal shingles, but with fewer style options and prone to denting.
- Copper Metal Roofing: Beautiful and unique, but more expensive than other metal roofing materials.
- Corrugated Metal Panel Roofing: These metal shingles are usually only used on smaller structures like a shed or small outbuilding.
- Zinc Roofing: Similar to copper, used more commonly in Europe because of the cost.
Pros and Cons
- Pros: Metal roofing materials are extremely durable. It lasts longer than asphalt or wood while offering high solar reflectance.
- Cons: Metal roofs are relatively expensive but are coming down in price and are still cheaper than slate. Standing seam metal roof is less expensive than over metal roofing types.
Metal ranges in cost between $5 and $14 per square foot for a standing seam metal roof. Aluminum or corrugated would be much less while copper would be much more.
Most metal roofing materials will come with a 30-year warranty, but most will actually outlive their warranties and last 50 years or more.
A metal roof is great in any climate. They tolerate both hot and cold temperatures and are strong enough to stand up to storms.
5. Clay Tile
Clay tiles are reinforced for strength and durability and have a natural thermal resistance which makes them a strong contender for eco-friendly building materials.
Pros and Cons
- Pros: Clay tile is durable, environmentally friendly, and very energy-efficient. It is also naturally resistant to fire and insects.
- Cons: Installation of clay tiles is difficult and expensive. They are also more susceptible to breakage than other materials.
Clay tiles are one of the most expensive, at between $10 to $18 dollars per square foot.
Most manufacturers will offer a 30-year warranty on their tile roofing materials. However, most roofs outlive that and can remain durable for up to 60 years or longer.
Clay tile roofs are particularly suited to homes in hot and humid climates in Spain and the Mediterranean, or just southwestern-style homes.
6. Concrete Tile
Concrete tile is manufactured with a unique blend of ingredients that maintains the strength of concrete but keeps the material lightweight and easy to work with.
Pros and Cons
- Pros: Concrete tiles are completely weather-proof in any climate. They require very minimal maintenance and are pest-resistant.
- Cons: Although lighter than typical concrete, this roofing material is still heavy and expensive to install.
The cost of concrete roof tiles varies greatly, but you can expect the total cost to be at least $20,000 and may exceed $40,000.
Concrete tiles rival clay tile in longevity, lasting at least 50 years. With the right underlayment and quality installation, concrete roofing material may last over 100 years.
Concrete tiles roofing can be used anywhere, but it is particularly well-suited to warm climates because it doesn’t absorb heat very quickly.
7. Rubber Roof
For commercial buildings with low-sloped or flat roofs, roofers often use rolled roofing materials called rubber roof.
Rubber Roofing Applications
- Flat and Low-Sloped Roofs: Shingles don’t work well on flat roofs because the water doesn’t shed off as easily, this is the most common application of rubber roofing.
- On Top of Your Shingled Roof: To extend the life of your roof, you can install rubber roofing on top of your existing shingles.
- Fixing a Metal Roof: Topping a metal roof with rubber roofing can extend the life of your roof without tearing off and starting over.
Types of Rubber Roofing Material
- EPDM: Stands for Ethylene propylene diene terpolymer. It was the original rubber roof and continues to have a great reputation for durability.
- TPO: TPO is an acronym for Thermoplastic Polyolefin, which is the primary chemical composition of most rubber roofing materials.
- PVC: This is a great material for rubber roofing because it is lightweight, reflective, and is particularly weather-resistant.
Pros and Cons
- Pros: Rubber roofing is cost-effective, eco-friendly, fire-resistant, and lowers the energy costs of large commercial buildings.
- Cons: Rubber is plain and doesn’t have any design or color options. Over time, it will age and become vulnerable to damage.
A rubber roof will start around $5 per square foot and may increase up to $8 per square foot. The overall cost will mostly depend on the type of roofing materials and the size of the roof.
When installed correctly, rubber roofing can last between 20-25 years.
Rubber roofing can perform well in both hot and cold climates as it is very weather-resistant.
8. Built-up Roofing (BUR)
Built-up roofing or BUR is one of the oldest systems still in use today. It uses is a combination of bitumen and fabric to create layers of membrane that are both cost-effective and durable.
Types of BUR
- Ballasted Asphalt Built-Up: This is essentially asphalt blasted on the roof’s surface without anchoring on the roof surface.
- Cold Built-Up: A cold built-up roof is bitumen applied using a squeegee to the surface of the deck and doesn’t produce toxic fumes.
- Hot Built-Up: A hot built-up roof uses liquefied bitumen and is the most difficult installation process.
Pros and Cons
- Pros: BUR is less expensive, easier to repair, and has lower maintenance than other materials. It is also naturally fire-resistant and impact-resistant.
- Cons: In some applications, BUR can produce toxic fumes. It takes time to install, and over time the surface can fade.
The cost of rubber roofing materials may be anywhere from $5 to $8 per square foot. That cost can increase based on the type of materials and installation.
If properly installed and maintained, a commercial built-up roof can last 40 years.
While a BUR roof can be used in any climate, it typically lasts longer in a warmer climate.
9. Rolled Roofing
This is a thinner material that is fast, convenient, and inexpensive but typically only used for small, low-slope outbuildings like shops and sheds.
Types of Rolled Roofing
- Bitumen Rolled Roofing: Similar to asphalt roofing materials, bitumen provides the best longevity in rolled roofing.
Pros and Cons
- Pros: It is a low-cost, easy-to-use option that is light, compact, and installs quickly.
- Cons: Rolled roofing is somewhat limited in design, lacks curb appeal, and has poor resale value.
The price of rolled roofing is less than $1 per square foot. It is a cheap roofing option for temporary or small-scale applications.
Rolled roofing typically only lasts about 10 years or so, which is why it’s not used on large-scale buildings.
Rolled roofing is best for hot climates, even though it does absorb heat, it does not easily get damaged by UV rays.
10. Solar Shingles
Solar shingles are essentially solar panels built designed to look and act like traditional shingles.
Types of Solar Cells
- Solar Shingles: Thin, rigid shingles in a frame installed in line with existing roofing materials.
Pros and Cons
- Pros: Solar shingles are beautiful and seamlessly fit in with traditional shingles. They are durable and require very little maintenance.
- Cons: Solar roofing materials are expensive, have limited styles, and take time to install.
The total installation cost for solar shingles is typically $60,000 – $75,000 but can pay for itself over time in energy costs.
Most solar shingles have a lifespan of 25-30 years. Over time they produce less power and will need to be replaced to continue energy savings.
Typically, solar shingles work best only on south-facing roofs due to the amount of sunshine necessary to recoup costs.
11. Green Roofs
One of the seven wonders of the world is a green roof, The Hanging Gardens of Babylon. Today’s green roof, or “living roof” is partially or completely covered with vegetation.
Pros and Cons
- Pros: There are seemingly endless benefits to a green roof including improved drainage and thermal performance. Supporting wildlife and air quality and an increased lifespan of the roof itself.
- Cons: Setting up a green roof is a very expensive project and requires proper maintenance. If not done correctly, it can be vulnerable to leaking into the building.
The initial costs of green roofs are more expensive, but their long-term maintenance can be drastically lower than other commercial options.
A green roof is set up on top of another roofing material. When done correctly, it protects the roofing material and can double the lifespan of the material used underneath.
Green roofs can be used almost anywhere because they can be customized for any region they are used.
