Roof Cutting Questions People in Diphu Ask Us Most
Before we go into details, here are quick answers to the questions we hear on calls and WhatsApp every week.
Will cutting my roof damage the house? Not if it is planned properly. Diamond cutting is controlled and creates little vibration. Always take your engineer's advice for major structural changes.
How long does it take? Many standard openings can be completed within a few hours to a day.
Is it very costly? It is usually more affordable than people expect, especially when you count the repair cost that manual breaking can create.
Do you need my drawing? It helps a lot. If you do not have one, we can still guide you after inspecting the site.
Can you work in tight spaces? Yes. We have wall saws and ring saws for such conditions.
What Is Roof Cutting?
Roof cutting is the process of cutting a marked section out of an RCC roof or slab. A diamond-tipped blade, cooled by water, slices through concrete and steel along straight lines. The removed portion comes out in blocks, and the opening is left clean.
You will also hear it called slab cutting, RCC cutting, terrace opening cutting, concrete floor opening or slab saw cutting. All of these point to the same service.
Roof Cutting in Simple Terms
Imagine drawing a rectangle on your roof with a marker and then cutting exactly along that line, with no cracks spreading beyond it. That is what diamond cutting aims to do.
Why Roof Cutting Demand Is Rising in Diphu
Diphu is expanding in many directions. New homes are being built, older houses are getting additional floors, and shops, colleges and offices are modernising their buildings. With every extension, a need arises to connect floors, bring in light and air, or install lifts. All of these require an opening in a concrete slab.
At the same time, people are more aware of structural safety. They know that a badly broken slab can weaken a building. This awareness is pushing owners toward professional cutting instead of rough demolition.
