Roof Tile

Roof tiles are a great option for homes in the Philippines, as they are known for their durability and long lifespan. 

Made of materials like clay and concrete, they are strong and resistant to weathering. They will never decay, and with proper maintenance, they can last up to 50 years.

Another advantage of roof tiles is their ability to withstand high temperatures and intense sunlight. Clay and concrete are non-combustible materials with high solar reflectivity, making them resistant to fire, UV radiation, and heat degradation. In the Philippines, where temperatures can reach over 30°C and the sun is strong year-round, the solar reflectivity of roof tiles can help lower air conditioning costs and reduce a home’s carbon footprint.

Roof tiles are also resistant to wind and water damage. In the Philippines, where typhoons and heavy rain are common, roof tiles are better able to withstand strong winds due to their relatively heavier weight. This makes them a better option than shingles and metal roofing, which can be easily lifted and blown off the roof.

Roof tiles provide excellent sound insulation. Their high density helps absorb sound waves, reducing the amount of noise pollution inside the building, especially during heavy rains. On average, roof tiles can reduce noise levels by up to 25 decibels compared to a reduction of 12 decibels for sheet metal. This is why roof tiles are highly recommended for high-noise areas.

In addition to their durability and weather resistance, roof tiles are also aesthetically pleasing. They come in a wide range of colors, styles, and textures, allowing homeowners to choose a design that suits their taste and the style of their home. Roof tiles can add a touch of elegance and sophistication to any home, enhancing its visual appeal and increasing its value.

In conclusion, roof tiles are a great choice for homes in the Philippines due to their durability, weather resistance, energy efficiency, and aesthetic appeal. When building a new home or replacing an existing roof, consider using roof tiles for a durable and attractive roofing solution.

One of the main disadvantages of using roof tiles in the Philippines is that they can be heavy and may require additional structural support to handle the added weight. This can add to the cost of construction and may not be feasible for houses with small budgets and older buildings that may not have been designed to support the added weight. Additionally, roof tiles can be brittle and may break when heavy objects fall into them like tree branches and hard fruits (e.g. coconuts) which are common in the Philippines. 

Furthermore, roof tiles can be difficult and time-consuming to install, especially for larger buildings or complex roof designs. This may require specialized labor and equipment, which may not be readily available in far-flung areas. In comparison, other roofing materials, such as metal sheets or asphalt shingles, can be easier and faster to install, making them a cheaper option.

Overall, while roof tiles have its advantages over other roofing options in the Philippines, they can also be heavy, brittle, and difficult to install. As such, it is important to consult with a tile roofing expert with deep trade knowledge and long industry experience to ensure the applicability of roof tiles in your particular home.

In the Philippines, roof tiles come in a variety of colors, from earthy tones to brighter shades, which could also complement any design, from traditional to modern.

One of the most common types of roof tiles used in the Philippines is the Spanish-style clay tile, also known as the “greda” or “teja”. This type of tile is made from natural clay, fired at high temperatures to make it strong and long-lasting. The tiles are then shaped by the machine into the characteristic S-shaped profile, which allows for overlapping and better protection against the elements. Clay tiles come in a range of colors, from terracotta and orange to reddish-brown, and are known for their rustic charm and traditional aesthetic.

Another popular roof tile option for Philippine house designs is concrete tile, which is made from a mixture of cement, sand, and water. Concrete tiles are molded into various shapes and sizes and can be finished with a range of textures and colors to mimic natural materials like wood or slate. Concrete tiles are known for their durability and resistance to extreme weather conditions, making them a practical and long-lasting option for Philippine houses.

There are 4 common roof tile profiles (or shapes), which are Double Roll, S-Type, Barrel, and Flat. Architects may choose from a variety of profiles that would properly match their designs. Below are some of the common roof tile profiles:

DOUBLE ROLL	S-TYPE
BARREL	FLAT

In terms of style, roof tiles can be used in a variety of house designs, from modern and contemporary to traditional and colonial. For example, a modern Philippine home may feature sleek, flat roof tiles in a neutral color, while a more traditional home may have curved, terracotta tiles that add a touch of Old-World charm. However, roof tiles are often associated with the “Mediterranean” style, which is characterized by its use of warm, earthy colors and patterns. This style is popular in the Philippines and can be seen in many homes throughout the country due to our long history with the Spanish.

When it comes to the history and culture of roof tiles in the Philippines, they have been used for centuries in traditional Philippine architecture.  In the past, they were used to signify a household’s wealth and status. In fact, many of the country’s heritage homes and buildings, such as the San Agustin Church in Manila, feature roof tiles as part of their design. This is because roof tiles are not only practical, but they also add a touch of elegance and wealth.

To install roof tiles, follow these steps:

1. Determine the type and size of roof tiles that are suitable for your home. This will depend on the design and style of your home, as well as the weather conditions in your area. In the Philippines, the most common types of roof tiles are concrete and clay.
2. Measure the roof area to determine the number of roof tiles you will need. To do this, measure the length and width of each section of the roof in meters, and then multiply these numbers to get the total area in square meters. You will need approximately 10-16 roof tiles per square meter, depending on the type and size of the tiles you choose.
3. Consider the weather conditions in the Philippines when choosing the type and color of your tiles. The country has a tropical climate with high temperatures, so light-colored tiles are recommended to reflect heat and prevent overheating.
4. Purchase roof tiles from a reputable supplier. In the Philippines, many companies sell roof tiles, and it is important to choose a supplier that offers high-quality products. Be sure to ask for samples, and compare prices and delivery times before making your purchase.
5. Install the under sheath. This is a layer of material that is placed over the roof structure and provides a solid, level surface for the roof tiles to be installed. In the Philippines, common materials used for under sheath include galvanized metal sheets, long-span pre-painted metal, or plywood. The under sheath should be attached to the roof structure and should be spaced according to the manufacturer’s instructions.
6. Install roof battens to support the tiles. These are placed over the under sheath and provide a surface for the tiles to rest on.
7. Install the roof tiles starting from the bottom of the roof and working your way up. On average, clay tiles usually weigh around 40-45 kg per square meter, while concrete tiles weigh around 50-55 kg per square meter.
8. Install the flashing, which is a strip of metal that is used to protect the edges of the roof and prevent water from leaking into the house. The flashing should be installed along the eaves, valleys, ridges, and hips of the roof, and should be carefully sealed to ensure that it is watertight.
9. Install the ridge and hip tiles. It covers the peak of the roof. Ridge tiles are secured by applying mortar underneath. These tiles should be installed according to the manufacturer’s instructions, making sure that they are level and evenly spaced.
10. Install roof vents to allow air circulation and prevent moisture build-up. Roof vents are typically placed along the eaves and the ridges of the roof, and are made of metal or plastic.
11. Install gutters and downspouts to collect and redirect rainwater away from the house. Gutters are typically made of metal, plastic, and concrete and are installed along the eaves of the roof. Downspouts are placed at the corners of the house and are connected to the gutters with brackets.

Installing roof tiles could be a tricky process and is prone to error when attempted by non-experts. Consider hiring a professional roofing contractor if you are unsure about any aspect of the installation process.

The weather in the Philippines involves heavy rainfall and typhoons during the rainy seasons from June to November. This can put a lot of strain on roof tiles, making regular maintenance and repair essential. Here are some tips to maintain your roof tiles:

1. Regularly inspect your roof tiles for any signs of damage or wear and tear. This should be done at least twice a year, especially after strong typhoons or heavy rainfall. It is also important to ensure that the roof is properly supported and that the tiles are securely attached to the roof. This can involve checking the condition of the roof framing and making any necessary repairs or replacements.
2. Clean your roof tiles regularly to prevent the buildup of dirt, debris, and algae. This can be done with a soft brush and a mild detergent solution. If using a brush, be sure to use gentle, circular motions to avoid damaging the tiles. If using a pressure washer, be sure to set the pressure to a low setting to avoid damaging the tiles. It is also important to avoid using any harsh chemicals or abrasive cleaners on the tiles, as these can cause the tiles to become damaged or degraded over time.
3. Repair any damaged or broken roof tiles as soon as possible to prevent further damage and leaks. This can be done by replacing the damaged tiles with new ones that match the size and shape of the original tiles.
4. Over time, the cement between the tiles may crack or crumble, leading to loose tiles and potential leaks. Re-bedding involves replacing the old cement with new mortar to secure the tiles in place. Re-pointing involves filling in gaps between the tiles with mortar, to prevent water from entering the roof.
5. Use a roof tile sealant to protect your roof tiles from water damage and UV degradation. This should be applied every few years to maintain the integrity of the tiles and prevent leaks.
6. Consider hiring a professional roofing contractor to inspect and maintain your roof tiles. They have the expertise and equipment to properly assess and repair any issues with your roof tiles.

To optimize your roof tiles for the Philippine climate, it is important to choose high-quality tiles that are durable and able to withstand heavy rainfall and strong winds. It is also essential to maintain and repair your roof tiles regularly to prevent leaks and damage.

Roof tile installation in the Philippines can vary in price based on several factors, including the type of roof tiles being installed, the size and pitch of the roof, and any additional features or services that are included in the installation. Here are some general guidelines to consider when determining the cost of roof tile installation in the Philippines:

1. Type of roof tiles: The type of roof tiles you choose will have a major impact on the cost of installation. For example, clay roof tiles are typically more expensive than concrete roof tiles, as they are also more durable and have a longer lifespan.
2. Size and pitch of the roof: The size of your roof and its pitch (the angle at which it slopes) will also affect the cost of installation. A larger roof or one with a steep pitch will require more materials and labor, which will increase the overall cost.
3. Additional features and services: Additional features such as skylights, solar panels, or ventilation will increase costs due to additional labor and other roofing material requirement.
4. Weather conditions: In areas with extreme heat or heavy rainfall, additional measures may be needed to ensure the durability and longevity of the roof tiles.
5. Location: Properties located in remote or difficult-to-access areas may incur additional costs for transportation and logistics.
6. Cultural and design considerations: A more complex design and other cultural/regulatory  considerations may also increase the cost of roof tile installation.

As a general rule, you can expect to pay anywhere from PHP 1,800 to PHP 3,000 per square meter for a roof tile installation in the Philippines. However, this is just a rough estimate, and the actual cost will depend on the factors mentioned above. To get a more accurate estimate, it’s best to contact a local roofing contractor and discuss your specific needs and budget.

Q. What are the most common types of roof tiles in the Philippines?

A. The two most common types of roof tiles in the Philippines are concrete and clay.  The standard size for concrete tiles is 13” wide and 16” long. Clay tiles have varying shapes and sizes, and are usually smaller than concrete tiles, resulting in more tiles per sq meter of roof area.

Q. How do I know which roof tiles are best for my house design?

A. The best roof tiles for your house design will depend on a variety of factors, including local regulations, your budget, and the overall aesthetic of your home. It is always best to consult architects for design specifications, or contractors and professional roofing companies to determine the best options for your specific situation.
