Why roof thermal insulation differs in Ghrnata

The centre of Ghrnata is at 24.7912, 46.7437, about 11 km from the centre of Riyadh, with an approximate radius of 2.8 km. The approximate area shown on the map is centred here. Ghrnata is mainly villas.

Ghrnata sits at roughly 24.7912, 46.7437, about 11 km from the centre of Riyadh, and its core covers an approximate radius of 2.8 km. Because the district is mainly villas, most roofs here are flat concrete slabs that take the full force of summer sun, so an emergency visit usually means a leak, a cracked slab or heat pouring through a single bedroom ceiling rather than a block of identical apartment roofs. Our crews plan each job around a detached house, with access to the roof, the staircase and any rooftop tank or unit that sits in the way.

The centre of Ghrnata is about 617 m above sea level, which is a useful detail for the work itself. Being on higher ground means the district can see strong, dry winds and sudden downpours that run off roofs quickly, so the surface has to be prepared properly before any product goes on. For emergency repairs, we start by clearing loose material and drying the slab where possible, then decide between a liquid roof waterproofing system at SAR 10–25 per m², a bitumen membrane at SAR 15–35 per m², or spray foam insulation at SAR 20–45 per m² depending on whether the priority is water or heat. Each option has a clear cost range, so owners can see the difference before work begins.

Owners in villas often avoid the same few errors, and the lessons are simple. Many skip cleaning the slab and paint over dust, which peels within a season. Others fix a visible crack without checking the edges, and a crack injection at SAR 40–125 per m often reveals more damage along its length. Some also insulate the roof while ignoring a rooftop water tank, even though a tank internal coating at SAR 25–65 per m² protects the water supply. Finally, owners sometimes rely on a cheap XPS board layer at SAR 15–30 per m² without sealing the joints. Our teams check these points first so the emergency fix holds.

If water is flowing, close the main valve first, then call or message with photos.

Signs worth paying attention to

If you notice one of these signs in Ghrnata, it is a good moment to talk to the team:

• Strong heat on the top floor
• The AC runs for long hours in summer
• The ceiling stays hot at night

The most common causes

• Old insulation that has deteriorated.
• No thermal insulation under the roof protection — we check this before anything else.

Tools we use in Ghrnata

The steps in order

1. Thermal survey: Hot areas of the roof are mapped.
2. Choosing the system: The material and thickness are agreed in the quote.
3. Installation: The layer is installed and protected.
4. Measurement and documentation: Thickness is measured at spread-out points.
