Lean to roof is basically a free-standing structure in which the wall of one side is built at a more height as compared to the wall at another side.
The lean-to roofs are widely used in the construction of the verandahs, sheds and go downs.
How to Build Lean-to Roof Structure?
The step by step procedure to build the Lean-to roof structure are as follows.
- Before starting the construction of the building it is necessary to do the site clearance and cut out all the trees and levelled the ground.
- The Marking of the foundation should be done on the site as per the plan.
- Then the excavation work should be carried out for the construction of the foundation.
- Dig the holes for the installation of the supporting posts. Ensure that the posts should be in the vertical direction.
- After installing the post holes into the ground, it should fix with concrete so that it cannot move from its position.
- In the lean to roof structure, the upper side of the rafters are rested on the wooden plate which is placed on the corbel.
- A corbel is basically a projection that comes out of the wall in order to support the structure which is resting on it. The corbel is a weight carrying member which is generally made up of stone or wood.
- The lower ends of the rafters are nailed and notched. The rafters in the lean-to roof are rested at an angle of 30 degrees at a wall.
- Notch the upper side of the post holes so that the rafter can be easily fitted or rest on it. After that set the nailery on posts.
- Fasten the nailery on the wall which has a higher length so that there you can attach the upper end of the rafter.
- The rafters should be properly attached and fixed to the wall. Then mark out the spacing of the rafter on the mailers.
- Determine the slope of the roof by stringing a line from the top side of the rafter towards the bottom side of the rafter.
- Attach all the rafters and fixed it properly. Then cover the roof by using suitable roofing material as per your requirement.
- There are various types of roof covers are used in the construction of the Lean-to roof such as A.C sheets or pre-coated sheets and Mangalore tiles etc.
Materials Which Are Used for the Construction of the Lean-to Roof
1. Clay Roof Tiles
The clay roof tiles are made up of baking moulded clay which are available in different types of colours such as white, orange and brown etc. This clay roof tiles are more durable as compared to the other types of roof tiles.
2. Glass Roofing
Glass roofing is one of the best roofing options which allows natural sunlight to enter into the structure. This also enhances the aesthetical look of the structure. But the transportation of the glass roof is difficult and there may be a chance of breaking.
3. Polycarbonate Roof
Polycarbonate sheets are very lightweight and very easy to carry from one place to another place. The polycarbonate has good impact resistance. Polycarbonate is a highly flexible material so that it can be moulded into various shapes as per the requirements of the construction.
4. Concrete Tiles
The concrete tiles are very affordable as compared to the other types of tiles. It has good strength and durability.
5. Asphalt Shingles
Asphalt shingles are one of the oldest roofing materials which are used in construction. The asphalt shingles have good resistance to fire.

- In case of the lean-to roofs the rainwater can be easily collected.
Disadvantages of Lean to Roof
There are also some disadvantages of lean-to roof which are as follows
- The Lean-to roofs are not suitable for the construction of large structures.
- The lean-to roofs have only one slope that’s why it may create the problem of water drainage when there will be heavy rainfall.
- In case of the lean-to roof the ceiling, itself takes the same slope as the roof that’s why there will be very little attic space.
- These types of roofs are not suitable for the areas where the wind flows with a very high velocity, it may lift up the roof.
- It requires more maintenance as compared to the other types of roofs.
- It is not possible to construct above in case of lean-to roof structures.
Conclusion of Lean to Roof
Roof is one of the important parts of our home so the selection of the type of roof on our depends on the various factors such as the budget, design of our home and the environmental conditions of the area. So, it is recommended that you should take all the pros and cons of the particular roof into consideration while the selection of the roof.
