What Is a Roof Cutting Service?
Roof cutting is the process of removing a planned section of a reinforced concrete (RCC) roof or slab using diamond-tipped cutting machines. Instead of breaking the slab with a jackhammer, the machine makes a straight, clean cut along a marked line. The cut piece is then lifted or broken down in a controlled way.
In simple words: you decide where the opening should be, and we cut exactly that part, without harming the rest of your building.
This method is popular because it protects the structure, saves time and keeps the site cleaner. It is especially useful in Lachung, where buildings are often close together, access roads are narrow and the weather can change within hours.
Why Lachung Needs Specialist Roof Cutting
Lachung sits at around 2,700 metres in North Sikkim, near Yumthang Valley and on the route to Chungthang, Lachen and Gurudongmar. It is a busy tourist village with many hotels, lodges and homestays, and a steady need for upgrades and repairs.
Local conditions make careful cutting very important:
- Cold climate and snow: Concrete work must be planned around temperature and moisture.
- Seismic zone: Sikkim is an earthquake-prone region, so structural care is a must. Random breaking of slabs is risky.
- Narrow roads and limited storage: Heavy machines and loud demolition are hard to manage. Our compact equipment is easier to move.
- Occupied buildings: Many hotels and homestays run all year. Low-noise, low-dust cutting lets you keep guests comfortable.
- Tourist season timelines: Owners often want work finished before peak months. Our fast cutting helps you meet that deadline.

Our Roof Cutting Process – Step by Step
We keep the process simple and transparent, so you always know what is happening on your site.
Step 1: Enquiry and Quick Discussion
Call or WhatsApp 7009679903. Share photos, the size of the opening and the slab thickness if you know it.
Step 2: Site Survey
Our team studies the slab, beams, columns and access route. We check for hidden pipes, wires and rebar patterns.
Step 3: Marking & Planning
The exact cutting lines are marked with you. We plan how the cut piece will be supported, lifted and removed.
Step 4: Safety Setup
We install props where needed, protect the floor below, restrict the area and organise water supply for cooling.
Step 5: Precision Cutting
The slab is cut along the marked lines using the right diamond equipment.
Step 6: Safe Removal
The cut portion is lowered or broken into manageable pieces and shifted from the site.
Step 7: Cleaning and Handover
We clear slurry, tidy the area and hand over a clean, ready-to-use opening.
Roof Cutting Cost in Lachung – Pricing Guide
The price depends on the work, so we always quote after understanding your needs. Here is what usually decides the cost:
- Slab thickness (a 125 mm slab costs less than a 250 mm slab)
- Total cutting length or area
- Density of steel reinforcement
- Type of machine required
- Height, access and working conditions
- Debris removal and finishing requirements
- Travel and logistics to Lachung
Indicative pricing (approximate): Roof and slab cutting is commonly charged per running foot or per square foot of cut. For typical RCC slabs, rates in Sikkim generally start from a few hundred rupees for small jobs and rise with thickness and complexity. Core drilling for pipes is charged per hole, based on diameter and depth. Because Lachung is a remote location, a small mobilisation charge may apply for transport and equipment.

Common Mistakes to Avoid While Cutting a Roof
- Breaking the slab by hand without planning. This can cause cracks and weaken the structure.
- Not checking the reinforcement. Cutting through main steel without design approval can be dangerous.
- Skipping temporary support. Cut sections can shift suddenly.
- Hiring only on the lowest price. Poor equipment and untrained workers can cost more in damage.
- Ignoring weather. Rain and snow in Lachung can disturb work timing and safety.
A good contractor will talk about these points with you before starting.
Tips to Prepare Your Site Before We Arrive
- Clear furniture and valuables from the area below the slab.
- Keep a water source and power point nearby.

These small steps help us finish faster and safer.
