The Charm of Rounded Dormers

Interview with Engineer Mihai Căplescu

When it comes to adding character and visual appeal to a building’s roofline, dormers play a crucial role. These architectural elements not only enhance the overall aesthetics but also provide additional space and natural light to the interior. Among the various types of dormers available, rounded dormers have emerged as a popular choice for architects seeking to create a unique and visually striking design. Rounded dormers are popular in Romania due to several factors that are influenced by the country’s architectural heritage, climate, and cultural preferences, one of our top technical consultants for roofers, engineer Mihai Căplescu, explains.   

This article explores why roofers might choose rounded dormers and the compatibility of Tegola Canadese’s Master bitumen shingles with this type of roof. 

 

Why Choose Rounded Dormers in the first place? 

Aesthetics: Rounded dormers are renowned for their soft, curved lines, which add a touch of elegance and charm to the overall architectural design. Their graceful appearance can enhance the curb appeal of any structure, making it stand out from the rest. 

Architectural Harmony: Rounded dormers offer a seamless integration with a variety of architectural styles, including Victorian, Georgian, and even contemporary designs. The gentle curves of rounded dormers create a harmonious transition between the roofline and the walls, providing a cohesive and pleasing visual effect. 

Maximizing Space: One of the primary reasons architects opt for rounded dormers is to maximize the usable space within the building. These dormers offer increased headroom and floor area, making them ideal for creating additional living space, such as cozy reading nooks, home offices, or even small bedrooms. 

Natural Light and Ventilation: Rounded dormers feature large windows, allowing an abundance of natural light to flood the interior space. The windows can also be designed to open, facilitating proper ventilation and improving indoor air quality.  

Engineer Mihai Căplescu has created hundreds of houses that feature the Tegola Master bitumen shingles and a few with rounded dormers specifically. We sat with him recently and asked him to tell us more about this interesting feature.  

I: What are, in your opinion, the reasons why rounded dormers have gained popularity in Romania?  

M: It is important to note that while rounded dormers have gained popularity in Romania, architectural preferences can vary across different regions and individual projects. However, the enduring appeal of rounded dormers in Romanian architecture can be attributed to their ability to evoke a sense of tradition, complement the climate, and create visually captivating designs that align with the country’s cultural and architectural heritage. 

Here, in Romania, as is the trend throughout Europe, there is a focus o preserving Traditional Architecture: Romania boasts a rich architectural heritage, with influences from various periods, including Gothic, Renaissance, Baroque, and Neoclassical styles. Rounded dormers align with the traditional design aesthetics seen in many Romanian buildings, especially in rural areas. These rounded elements add a sense of charm and character that resonates with the country’s architectural heritage. 

Also, rounded dormers often evoke a nostalgic sense of tradition and cultural identity. In Romania, there is a deep appreciation for preserving and celebrating local heritage. Rounded dormers, with their timeless appeal, contribute to the preservation of traditional architectural styles and help maintain a connection to the past. 

On another note, there are also the climate considerations, Romania experiences a range of weather conditions, including cold winters and hot summers. Rounded dormers offer practical benefits in terms of energy efficiency and ventilation. The curved design helps to prevent snow accumulation and allows for better airflow, making them suitable for adapting to the country’s climate. 

Architects also use the rounded dormers features for visual harmony as well – rounded dormers create a harmonious and visually pleasing roofline, blending seamlessly with the overall architectural composition. This design choice contributes to the balanced proportions and aesthetics of Romanian buildings, which often prioritize symmetry and graceful lines. 

Romania has a rich cultural heritage, with folklore and traditional stories deeply woven into the fabric of society. Rounded dormers can sometimes be associated with folklore and local tales, adding a touch of whimsy and storytelling to the architectural narrative. 

 

I: What are the main characteristics of the rounded dormers roof and what can people expect when choosing it?  

M: Designing and building a roof with rounded dormers is pretty challenging, if I can say so. Starting from the the base layer – the wood (support layer) that has to start by being installed on the rounded shape from the get go.  

Furthermore, the next layers on the whole structure (bearing in mind that some of the underlayements can be pretty rigid)  will have to be brought to the rounded shape.   

Next, the carpentry (wood, pvc or alluminum) will have to be converted (windows included) to the semicircular shape.   

On the outside, the valley will resemble an elypse, or more like an irregular shape with a high degree of difficulty during installation, in order to have that perfect surface finish in the end.   

The top of a rounded dormer is the zero slope point, reason why my choice is Tegola’s bitumen shingles and sometimes metal roofing. However, regardless of the choice of surface materials, the stratigraphy should create a ventilated roof, that means creating a ventilation layer on top of the thermal insulation. 

On the roof decking the roofer first installs the vapour diffusion layer (Vapobar/Difbar). Next, a grid of slat in installed to create the ventilation space and on top of that comes the roof deck that acts as the support layer for the shingles (for Tegola Canadese – OSB III).   

An important fact to note is that the valley and the area of zero slope to the 15 degrees slope are protected against water infiltration with bitumen membranes such as Tegola’s Safety line.  

It is my opinion that these types of rounded dormers can prove to be a bit more work overall, specifically when it comes to the installation, however, when executed flawlessly, the pleasure of the finished work is totally worth it.   

I: Why have you used Tegola Canadese’s bitumen shingles for the rounded dormers: 

M: When it comes to roofing materials for rounded dormers, Tegola’s bitumen shingles – specifically Master Line are my choice for several reasons: 

1. Design: Master’s combinations of overlapping layers has helped design a seamingly effortless roof with smooth lines that still give that personality to the structure, reasons why it has been a pretty popular option for home owners specifically.  

2. Durability: Tegola Canadese’s bitumen shingles are known for their exceptional durability and resistance to harsh weather conditions. They can withstand heavy rain, wind, and UV exposure, ensuring long-lasting protection for the roof and the dormer structure.  

3. Versatility: these are available in a wide range of colors and textures, offering architects ample options to match the design intent of the building. They can seamlessly blend with various architectural styles and provide a beautiful, cohesive roofline. 

4. Ease of Installation: Bitumen shingles are relatively lightweight and easy to install, making them a preferred choice for rounded dormers. Their flexibility allows them to conform to the curved surfaces of the dormer seamlessly, ensuring a neat and visually appealing finish. 

5. Cost-Effective: Bitumen shingles offer an affordable roofing solution without compromising on quality or aesthetics. They provide excellent value for money, considering their durability, low maintenance requirements, and long lifespan. 

Rounded dormers have become a favored architectural feature due to their captivating aesthetics, space-enhancing properties, and compatibility with various architectural styles. When it comes to roofing materials for rounded dormers, bitumen shingles offer a winning combination of durability, versatility, ease of installation, and cost-effectiveness. By choosing rounded dormers and pairing them with bitumen shingles, architects can create visually stunning structures that stand the test of time while providing additional functionality and charm.

Halala Kella Lodge

Roof made with Master grigio pietra by Tegola Canadese

Located on high ground abutting beautiful basin created by a hydroelectric dam on the Omo River in southern Ethiopia, Halala Kella Lodge is named after the iconic 1,200-kilometer-long “HALALA” wall built between the 13th and 16th centuries to defend the Dawro people and their precious and fertile lands.  This impressive wall built entirely of stone and mud takes its name from King Halala who completed its works. The resort covers an area of 12 hectares and is located between 900 and 1000 meters above sea level. 

This magnificent resort was directly desired by the Ethiopian Prime Minister office as part of the “GEBETA LEHAGER project,” a tourism development project “for the good of the country.” 

A.COM.EX for Halala Kella Lodge, followed all processes for the definition, quantification and coordinated selection of materials used; coordination of material procurement, plant design and executive design of roofing; logistics, sea loading and transportation to the site. 

Tegola Canadese Master grigio pietra was chosen for the roofing, as it was considered the best product to ensure perfect waterproofing of truncated-cone roofs and at the same time offer great aesthetic value to the lodge, for integration with the beautiful natural surrounding landscape. 

Particularly appreciated by A.COM.EX was the collaboration with Tegola Canadese, especially with the area manager Danilo Maiolatesi for technical and commercial assistance throughout the negotiations and the technical department for support during the design and execution of the work, sharing important suggestions par facilitate the installation and ensure waterproofing and aesthetics in the smallest details.

Atelier Fleuriste

Asphalt Shingles

Chieri (TO), 2002 / 2008

Roof made with Prestige Compact metal shingle by Tegola Canadese

The project, which includes the complete renovation of a nineteenth-century brick house and the construction of a new building in the internal garden, stems from the desire to strongly mark the presence of an uncommon place, inside a disorderly urban context, caught between memories of the rural town and the recent building interventions. The functional program provides for the creation of exhibition, commercial, residential and informal spaces designed in a flexible way, adaptable to the different needs of the principal. The intervention is divided into two building blocks, formally very different, one conceived as a large showcase-square on Via Andezeno, the other as an isolated pavilion inside the garden open to the public, visible from the street through perspective glimpses.

The renovation of the brick building provides for keeping the central portion intact with all its characteristics: the vaulted roofs, the windows, the plaster and the decorations, while on the sides the original shape of the building has been reconstructed with a large full-height window towards the street and an iridescent copper cover towards the courtyard. The interior space is completely open and is articulated around a large full-height void, crossed by walkways and designed to accommodate large-sized installations and lighting elements. The cooling system of the window consists of a veil of running water that transforms the entire front of the building into a real monumental fountain: the street thus becomes a square, a public space of reference for the entire urban context. The pavilion inside the garden consists of an articulated and fluid plastic volume, raised from the ground by large concrete partitions and covered with a broken brick cover that gives it a strong material character.

Finally, the garden, which includes a public parking servicing the atelier, can be set up to directly communicate with the large void, inside the exhibition and commercial space, through a glass wall that can be opened, becoming the ideal place for outdoor installations and events.

Vana Nava Water Jungle Park

Asphalt Shingles

Hua Hin Thailandia, 2014

Vana Nava Water Jungle is an oasis of fun in the heart of Hua Hin, Thailand, nestled in the lush landscape that engulfs the water park. Vana Nava’s Hua Hin Water Jungle incorporates iconic architectural and design elements with organically shaped canopies and a variety of exotic plants and tropical trees.

For this water park, the design and construction team created a 6400-square-metre jungle where nothing existed before, planting 200,000 trees and plants. Many of the trees are between 30 and 40 years old, recovered from areas involved in the construction of infrastructures or supplied by the landscape architect.

The designers refer to the site, which opened in 2014, as the first ecologically conscious water park in the region. The outstanding feature of Vana Nava Hua Hin Water Jungle is the synergy with nature and the integration of a water park in a tropical forest (The Green Mechanical Engineering).

To build this, they were inspired by the shapes of nature such as the leaves of trees or the fish in the sea but also by the lifestyle of fishermen in order to reflect the history of the seaside town of Hua Hin which has now become a very famous tourist resort in Thailand.
