When we talk about ceramic roofs, it's common to focus only on the main tiles. However, the actual performance of a roof goes far beyond that. The complementary pieces play an essential role in the sealing, ventilation, finish, and durability of the roofing.
Ignoring or misusing these parts can lead to problems such as leaks, tile displacement, poor ventilation, and even structural damage over time.
Main complementary parts for ceramic roofs
Complementary roof tiles are designed to address specific points on the roof where standard tiles cannot provide adequate sealing or finishing. Below are the main types:
1- Ridge;
2- Half tile;
3- Wooden clog;
4- 3-Way; 5- Ridge end; 6- Ventilation tile; 7- Bird netting; 8- Left and right side finishing.
1- Ridge
The ridge is one of the most important parts of the roof. It is used at the highest point of the roof, where two slopes meet.
Its main function is to seal this joint, preventing the entry of rainwater, wind, and dirt. In addition, it contributes to the aesthetic finish of the roof.
The installation should be done at the correct angle and, preferably, using specific fastening systems, ensuring greater strength and durability.
2- Half tile
Half-tiles are used for fitting adjustments, especially at the ends of the roof or in places where full-tiles do not fit correctly.
It is essential for maintaining the alignment of ceramic tiles and preventing open spaces that could cause leaks.
It also helps to reduce improvised cuts, which improves the final finish and reduces waste on the job site.
3- Clog
Its main benefit lies in reducing the use of mortar, which allows for a more practical application and a more aesthetically pleasing result.
Furthermore, its use contributes to a better standard of finish, enhancing the overall value of the roof.
The 3-way fitting is used on roofs with three-pitched junctions, that is, where three sloping planes meet.
It functions as a transition point, ensuring sealing and aesthetic continuity in this type of more complex structure.
Without this part, it would be very difficult to guarantee a good finish and prevent leaks in these critical areas.
5- End of spike
The ridge end is used at the ends of the sloping roof lines, called ridges.
Its function is to finalize the fitting of the ridge tiles at these points, providing a seal and a more refined finish.
In addition to its visual appeal, this piece prevents water from entering and protects the structure from wind damage.
The ventilation tile is responsible for allowing air circulation inside the roof.
It helps reduce the buildup of heat and moisture, contributing to greater thermal comfort and preventing problems such as mold and structural deterioration.
It is especially important in hot regions or in projects with ceilings, ensuring greater thermal efficiency.
7- Bird net
Bird netting is installed on the eaves of the roof to prevent birds, insects, and small animals from entering.
In addition to protecting the structure, it also prevents the accumulation of dirt and potential blockages in the gutters.
This part is simple, but extremely important for the maintenance and preservation of the roof over time.
These pieces are used on the sides of the roof, ensuring a proper seal at the ends.
They prevent water from entering from the side and significantly improve the visual finish of the roof.
In addition, they contribute to securing the roof tiles, increasing resistance against strong winds.
Where should each complementary piece be applied to ceramic roofs?
Now that you know the main components, it's essential to understand exactly where each one should be applied to the roof:
Ridge cap: should be installed at the top of the roof, at the junction between two roof slopes.
Half tile: used on sides or for fitting adjustments, mainly on edges and cutouts.
Wooden block: applied below the ridge, serving as a support base.
3-way: used where three roof planes meet. Ridge end : installed at sloping ends, completing the ridge line.
Ventilation tile: distributed along the roof, usually at strategic points for air circulation.
Bird guard: applied to the eaves, at the entrance to the roof.
Side trim: installed on the left and right sides of the roof.
Each of these parts has a specific function and must be positioned correctly to ensure maximum performance of the ceramic tiles.
A common mistake in construction is replacing these parts with makeshift solutions, which can compromise the entire roof.

Conclusion
Ceramic roof tiles are known for their strength, durability, and aesthetics. However, to achieve their full potential, it is essential to use the correct complementary pieces.
Every detail of the roof matters, from the ridge cap to the eaves with the bird netting. When properly installed, these components ensure efficient sealing, better ventilation, protection against external elements, and a much more valuable finish.
