How to add roof a overhang

28th February 20220

A roof overhang also known as eaves protects the building under it from rain and weather. The overhanging edge of the roof also gives extra shade to the windows, preventing glare and heat from entering the home. Adding an overhang isn’t a very difficult job. However, blending the new overhang into the existing roof requires some expertise.  

Accessing the roof –  

Firstly, start by taking off the existing fascia and any other trim that covers the rafter tails. Once the rafter tails and top of the wall plate are exposed, you should be able to see into the loft.  

Extending the rafters –  

Secondly, cut the rafter extensions three times the length of the overhang you want to add. Then, position the rafter extension against the existing rafter. Make sure that two-thirds of their length overlap’s the rafters, defining the overhang. You should nail an extension to each rafter spaced 6 to 8 inches apart. The overhang should be 2 feet or less to ensure it would be stable.  

Installing fascia’s and soffits –  

Once the new overhang is on you can then start the fascia and soffit installation. Attach a new two-by-four sub-fascia board along the ends of the new rafter tails. The fascia board is nailed it the rafter and usually has a lip for the soffit boards to slot into. To build a soffit, attach a two by four nailer board to the wall of the building, making it level with the bottom of the fascia.  

Adding the roof to the overhang –  

Once the overhangs are framed, you need to cover the rafter extensions with a fresh layer of plywood sheathing. The best way to integrate the new overhang into the roof is to remove the underlay and shingles from the entire roof and put new ones on. If you use new shingles, the new overhangs will disappear into the roof. If you don’t want to reroof, then you’ll have to settle for a less than perfect blend. Your biggest problem may be finding roof shingles to match the ones on your house.

Understanding the anatomy of a roof part 2

25th January 20220

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.   

Fascia –  

Firstly, a fascia is the attractive board along the side of the overhang and helps your roof appear finished. They are used to secure the gutters to the roof and keep them in place. Fascias also block water from penetrating the roof deck and coming into your home.  

How is a fascia attached? The fascia board is nailed to the rafter feet and usually has a rebate or lip for the soffit boards to slot into. They are then either fixed to a batten that is attached to the brickwork or sat on top of the last course of brickwork.  

Soffit –  

The soffit is the part of the overhang where your roof meets your siding. When rain or snow hits your roof, it runs down, and the overhang allows the water to flow away from your house. Soffit outlining the roofline allows for continuous ventilation and is one of the most effective ways to ventilate a loft.  

Where is the soffit on a house? The soffit is the material beneath the eave that connects the far edge of your roof to the exterior wall of your house. Besides being underneath your eaves, soffits can also be on the underside of a porch.  

Gutters –  

Guttering is a small thin trough that is used to collect water from your roof and completes the roofing protection system. It is used to direct rainwater away from the base of the building which helps protect the foundation. For a house to be complete, it needs a gutter system to function properly.  

Downspout –  

A downspout is a lightweight tube that extends vertically from the gutter trough to the ground. They exist to direct excess rainwater away from your home in a controlled manner. In addition, it is an important element of any gutter system that helps prevent soil erosion and damage to the property’s foundation.  

Flashing –  

Finally, flashing is a crucial roofing material that every roof needs to have. It is a sheet of thin metal material used to prevent water penetration or seepage into a building. Without flashing a roof would almost certainly develop leaks in sensitive areas.

A guide to words and terms used in architecture

7th December 20210

From architecture to construction terms, it is easy to feel left in the dark especially if you’re not an architect or a construction worker. To help you avoid confusion here is a list of some important words to familiarise yourself with before you meet with an architect or have any work starts.  

BIM –  

Firstly, BIM stands for ‘building information modeling. It’s a 3D model-based process that architects use to reduce errors and help the client envision a project. It digitally helps them plan, design, and construct buildings.  

Cladding –  

building cladding is the application of one material over another to add an extra skin or layer to the building. It could be any material wood, metal, stone. It needs to be waterproof because it is used to protect the building against leaking.  

Scale –  

Scale terms can refer to a few things. Firstly, it’s a triangular, ruler-like device used to determine dimensions. But more often, you’ll hear architects use the term in a statement like, “The scale is all wrong.” In that case, scale refers to how the sizes of different architectural elements relate to one another. 

Truss –  

A truss is a supporting structure or framework that’s composed of beams, girders, or rods, usually made of steel or wood. It usually looks like a triangle, as it’s the frame that supports the building’s roof.  

Carbuncle –  

A building that is extremely unpleasant to look at.  

Prefabricated –  

A prefabricated building is built in sections that can be moved and put together quickly.  

Cornice –  

Derive from the Italian word meaning ledge, a cornice refers to any horizontal, decorative molding that crowns a building.  

Spatiality –  

A general term that refers to anything relating to, involving, or having the nature of space.  

Massing-  

The general shape, or shapes of a building, as well as its form and size. You could compare it to the overall composition of a painting but in case it’s three-dimensional.  

Derelict –  

Something such as a building or piece of land that is derelict is empty, not used, and in a bad condition.  

Cantilever –  

These terms refer to any type of beam that’s only anchored at one point. Architects often refer to cantilever when discussing overhanging planes, like a cantilevered roof or deck.  

Dormer –  

A structural element of a building that protrudes from the plane of a sloping roof surface. Dormers are used to create usable space on the roof of a building by adding headroom and windows.  

Fascia –  

Finally, a horizontal board is attached to the lower end of rafters at the eaves.

What are eaves in architecture?

29th November 20210

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.
