In short: Roof cutting means cutting a planned opening in an RCC roof or slab with diamond tools instead of breaking it by hammer. In Lumding, the usual cost is about ₹80 to ₹250 per running inch, based on slab thickness, steel and access. Try our rate calculator for a quick idea.
What Is Roof Cutting?
Roof cutting is the controlled removal of a portion of a concrete roof or slab. A diamond blade, cooled with water, cuts through both concrete and the steel bars inside it. The cut line is straight and clean, and the rest of the structure is not disturbed.
You may also hear it called RCC slab cutting, concrete roof opening, terrace cutting or slab saw cutting. All of them mean the same basic idea: cut only what is needed, nothing more.
Why It Matters for Lumding Buildings
Lumding is a busy railway town with a mix of old and new construction. Many houses and quarters were built decades ago with thick RCC slabs and heavy steel. Families now want to add a terrace stair, install a home lift, or merge two rooms. Shop owners near the market want a bigger opening or a mezzanine. For such changes, breaking the slab with a hammer is risky. It sends shocks through the whole building and can crack beams that are still in good condition.
Diamond cutting gives you a safer and neater way to do the same job.
Our Concrete Roof Cutting Solutions in Lumding
Terrace Staircase Opening
The most common job. We cut the slab to the exact stair size so that your mason can start construction immediately.
Home Lift and Elevator Shaft Opening
We make accurate openings for lift shafts in homes, hospitals, hotels and apartments, matching the dimensions given by the lift company.
Skylight, Duct and Shaft Cutting

Technology Behind Modern Roof Cutting
Not every cut needs the same machine. Here is how we choose.
Slab Saw (Floor Saw)
Best for straight cuts on flat terraces and floors. It is quick and gives smooth, accurate lines.
Wall Saw and Ring Saw
These are used where space is limited or where we need a deeper cut. They are ideal for corners and edges that a slab saw cannot finish.
Diamond Wire Saw
When the concrete is very thick or the area is hard to reach, a flexible diamond wire is looped around and pulled to cut the structure gradually. It is used for heavy beams, thick slabs and special projects.
Core Drilling Machines
For round holes, a diamond core bit drills cleanly through concrete. Often, we drill the four corners of an opening first so that the cut does not over-run.
Why Diamond?
Diamond is harder than concrete and steel. When water-cooled, it cuts smoothly without burning the blade or shaking the structure. This is why it has become the standard method for modern renovation.

These are approximate market-style ranges and not a fixed rate card. Final charges are confirmed after seeing your site.
Factors That Change Your Quote
- Thickness of the slab – deeper cuts need more time.
- Amount of reinforcement – dense steel slows the blade.
- Total running length – the perimeter of your opening.
- Floor level and access – higher floors and narrow lanes need more handling.
- Water and electricity – both are needed for smooth work.
- Number of cuts – bigger combined jobs often get better rates.
A Simple Example
Let's say you want a lift opening of 5 ft × 5 ft. The perimeter is 20 ft, which equals 240 inches. Multiply this by the per-inch rate for your slab thickness, and you get a basic cutting estimate. Our rate calculator does this for you in seconds.

Roof cutting involves heavy concrete, so safety is not optional.
- Structural awareness: We never cut load-bearing members without clearance from an engineer.
- Hidden services check: Wires, pipes and conduits are checked before cutting.
- Propping: Temporary supports are used where the structure needs them.
- Controlled block removal: Pieces are cut to a size that can be safely handled.
- Barricading: No one is allowed under the cutting zone.
- Safety gear: Helmets, gloves, goggles, ear protection and safety shoes are worn on site.
- Electrical safety: Proper earthing and water-safe connections are maintained.
Please note: Any structural change should be approved by your structural engineer or architect. We are happy to work with them.

How to Pick the Right Roof Cutting Contractor
Ask yourself:
- Will they visit the site first?
- Do they use proper diamond equipment?
- Is the quote clear and written?
- Do they take safety seriously?
- Can they explain the process in simple words?
- Are they easy to reach on call or WhatsApp?
A good contractor will answer these questions openly. If someone only gives a number on the phone without asking about thickness or access, be careful.
Quick Preparation Checklist Before We Arrive
- Keep your drawing or engineer's marking ready.
- Arrange a water point and power supply near the work area.
- Move furniture and valuables from below the slab.
- Inform neighbours, especially in shared buildings.
- Share photos of the roof on WhatsApp to speed up the quote.
