Understanding All Of The Details Of A Roof

When it comes to the roof of your home, there are quite a few components. Here you can gain an understanding of all of the details that make up a roof.  

What is a ridge?  

Firstly, the ridge is defined as the highest point on a roof, often referred to as the peak. It is a horizontal line running the length of the roof where the two planes meet. 

A ridge beam is a necessary structural member that carries half of the roof load and must be used when building roofs with slopes less than 3/12.  

 If you are thinking of installing a loft conversion, you must measure from the floor to the ridge height to see if you have a minimum head height of 2.2 m.  

What is a hip?  

A hip roof has no vertical ends. It is sloped on all sides, with the slopes meeting in a peak. The hip is the external angle at which adjacent sloping sides of a roof meets.  

The hip provides the ideal protection from the weather, like heavy rain, snow, and high winds. This is because the sides are sloped towards the ground so the weather can slide off and makes the building more stable.  

Rafters –  

A rafter is a structural component that is used as a part of the construction. Typically, it runs from the ridge or hip of the roof to the wall plate of the external wall. Rafters contain two main outer beams which support the structure. In addition, they are usually laid side-by-side, providing a base to support roof decks and coverings. 

Valley –  

A valley is a gutter-like valley that runs between two sloped sections. They are used so that the rainwater has somewhere to escape.  

Although just like gutters, valleys undergo a fair amount of wear over time. They can leak, rust, and get blocked up; however, the repairs are a common situation and easy to fix.  

They are typically made of lead, concrete, or fiberglass. Although, aluminum is now growing in popularity, as a lightweight and rust-resistant alternative to older iron/ steel valleys.  

Rakes –  

The rake refers to the slanting edge of a gable roof at the end wall of the house. This f is most common in colder climates and consists of two sections sloping in opposite directions from the peak to allow for the best flow of water off the roof.  

They are important because they help keep your roof dry and they serve the important function of preventing water from getting into the fascia.  

Shingles –  

Finally, shingles are coverings consisting of individual overlapping elements. These elements are typically flat, rectangular shapes laid in courses from the bottom edge of the roof up. With each course overlapping the joints below.

Everything you should know before building a Flat roof

Flat roof extensions can provide a simple, cost-effective solution that ticks all of the right boxes. Especially for smaller extensions.  

What is a flat roof? 

A flat roof is a roof that is completely or almost level. However, whilst they are described as flat almost all flat roofs are laid to slope so that rainwater can run off to the lower side. The slope of the roof is properly known as its pitch. 

Where flat roofs originally from –  

Flat roofs are an ancient form mostly used in desert climates. Flat roofs exist all over the world, and each area has its own tradition or preference for the materials used. For hotter climates, where there is less rainfall many flat roofs are simply built out of masonry or concrete. This is because it is good at keeping the heat out, it is cheap and easy to build. Flat roofs are characteristic of the Egyptian, Persia, and Arabian styles of architecture.   

The main thing flat roofs are used for is extensions. They are exceedingly popular with those looking to create a cool, modern home. Flat roofs help to free up internal space and are often cheaper than a pitched roof. It is also easier to incorporate a green roof onto the structure if you want to go for an eco-friendly version.  

Pros and cons of flat roofs –  


  • Installation & Maintenance – flat roofs are fairly easy to install. The maintenance is also easy because there is no fear of sliding off the roof when it comes to fixing it or cleaning the gutters.  
  • Price – the flat roof is generally a less expensive option. A flat roof requires less materials for the construction, and the materials are cheaper than tiles. They also take less tome to install.  
  • Internal space is not imposed on – the lack of pitch means that you don’t have to extend your property upwards, and maybe block some views. You can also put things on top of the roof and create a roof top garden  


  • Temperature change – flat roofs absorb heat easier than flat roofs, because they are constantly absorbed by the sun. In the summer this can make your house very hot, however, in the winter it does the opposite and makes your house cold.  
  • Roof repairs – they are usually more expensive than a traditional pitched roof.  
  • Drainage – flat roof drainage is not as effective as pitched roofs and flooding can become an issue.

What are eaves in architecture?

What are eaves in a house?  

The area where a roof extends a small way past the wall of a building is usually referred to as the eaves. The term ‘eaves’ typically refers to the combination of soffit and fascia that adorn the overhang of a roof. 

Types of eaves –  

There are four basic types: 

  • Exposed – the finished underside of the roof and supporting rafters are visible from the underneath.  
  • Soffit – includes a soffit – the panelling which forms the underside of the eaves, connecting the bottom tip of the eave with the side of the building at a 90-degree angle.  
  • Boxed in – encases the roof rafters but meets the side of the building at the same angle as the roof pitch. 
  • Abbreviated – cut off almost perpendicular with the side of the building.  

Are eaves the same as soffits?  

To summarise the difference between the two, the eave is an area of the roof which overhangs the walls, whereas the soffit is the underside component of this area. In the widest sense, soffits can refer to the underside of almost anything that’s constructed, including arches and porches. An eave is part of a roof system and a soffit is part of the eave. In simple terms, eaves and soffits are two different parts of the same structure.  

Why do you need them?  

They can define the style of a home, and they also have a major function. They can protect the siding and foundation of a structure. A roof’s eaves sticking out beyond the sides allow snow and rain to fall from the roof away from the sides and to the ground. This can prevent leakage-related damage to the building façade.  

Eaves can also provide shading to windows, helping to maintain comfortable internal conditions. In the winter the low sun is able to enter through the windows to warm the interior. Whereas, in summer, they prevent direct sunlight from entering your home.  

How much does it cost to replace eaves on a house?  

The average cost to repair roof eave damage can be anywhere between £345 – £1000. However, most people pay around £675 to have a carpenter repair a 30 linear feet section of the soffits and fascia damaged by moisture or insects. The maximum cost of roof eaves can go up to £3,100.

The Top 7 Best And Most Useful Types Of Roofs

Gable Roofs  

Firstly, gable roofs are one of the most common types of roofs in colder climates. It consists of two sections whose upper horizontal edges meet to form its ridge. In regions with strong winds and heavy rain, gable roofs are built with a steep pitch in order to present to prevent the ingress of water.    

They are recognised by their triangular shape. 

Gable roofs are friendly to all types of materials. However, if they contain hips and valleys, consider using metal shingles or standing seams to avoid leaks.  


  • Inexpesnive    
  • Are based on simple design principle 
  • More weather-resistant than flat roofs  
  • The loft can be turned into living  space  


  • Gable roofs are more prone to wind damage than hip roofs   
  • Gable roofs can collapse if frames are not constructed properly

Mansard roof   

Secondly, A mansard roof is a four-sided gambrel-style hip roof. It has two slopes on each side. Punctured by dormer windows, at a steeper angle than the upper. This type of roof with windows creates additional floor and living space.  


  • The mansard style makes maximum use of the interior space of the loft  
  • A simple mansard roof is rather cheap  
  • Extra living space adds value to the house  


  • A typical mansard can be costly  
  • A low pitched mansard roof is not recommended for use in places with high rainfall 

Hip roofs 

Thirdly, a hip roof is a type of roof where all sides slope downwards to the walls. They usually have four sides like a mansard roof, often shaped like a pyramid. There are three types of hip roofs: simple hip, crossed hip, and half-hipped. However, simple hip roofs are the most common.  


  • Durable and sturdy  
  • It is excellent for windy areas  
  • Offers extra living space  


  • Expensive and complex 
  • Can develop water leaks if not well installed 
  • Requires extra maintenance

Shed roof  

A shed roof is a single sloping roof attached to a taller wall. A shed roof doesn’t have any adjoining roofs. And can be installed on an independent building or leaned into an already existing one.   

They are mostly used for home additions and are getting popular with modern home roofing. This roof is used for eco-friendly houses.


  • Suitable for rain regions 
  • Less expensive
  • Allows natural light  
  • Easy to assemble 


  • When the pitch is too high, the ceiling becomes low. 
  • Not suitable for areas with high wind

Gambrel roof  

 A gambrel roof has two different slopes, one side is almost vertical steep slope while the other slope is lower. This design provides the advantages of a sloped roof while maximising headroom inside the building’s upper level. Gambrel roofs are also getting popular in modern builds.  


  • It allows extra living space 
  • Easy construction 
  • Less expesnice  
  • Provides more storage 


  • Regular maintenance 
  • Needs to be water proof at the ridges 
  • Not usefull in high wind areas  
  • Windows may increase the chances of leaks 

Flat roof  

Flat roofs are often not 100% flat, there is a slight slope that allows water to run off. They also have centrally located drains and gutters to get rid of the rainwater on top of the roof. Flat roofs are common to commercial and industrial buildings. Flat roofs are often used in warmer climates, which allows the roof space to be used as a living space.


  • Less expensive to construct 
  • Suitable for installing solar panals when constructing an eco friendly house  


  • Not suitable for high rainfall areas  
  • Frequent maintence and repairs

Bonnet roof  

Finally, bonnet roofs are like a reverse mansard roof. They have double slopes, the lower slopes are at a lesser angle than the upper slopes. In addition, if you have an open porch the lower slopes are good because they overhang and create a cover.  


  • They allow dormers  
  • Overhanging eaves provide protection from water damage  
  • Durable 
  • Bonnet roof allows extra living spac for a small loft 


  • Difficult to construct 
  • More expensive 
  • Need complex materials
