Roof waterproofing for offices & commercial complexes in Afif

Roof waterproofing in Afif: the local context

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Team note on Afif: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

Roof leaks are the most common problem we see on office buildings and commercial complexes in Afif. Flat roofs collect water at drains, parapets and joints where the membrane has aged or lifted, and the damage often shows first as stains on upper-floor ceilings rather than as a visible puddle. Left alone, trapped moisture weakens the insulation and the concrete beneath, which turns a small patch repair into a much larger job. Our liquid roof waterproofing is priced from SAR 8 to SAR 25 per m², and bitumen membrane from SAR 15 to SAR 35 per m², so the right choice depends on the roof's condition and how much of it needs treating.

Afif sits about 1040 m above sea level, and that altitude shapes the approach. Higher ground in this part of the region brings a wider daily temperature swing, so roof surfaces expand and contract more and stress the coatings and joints over time. Our teams therefore check the condition of existing membranes and sealant lines before choosing a system, and they look closely at expansion joints and the junctions where the roof meets walls and plant platforms. Where the roof needs thermal protection as well as waterproofing, XPS boards at SAR 12 to SAR 30 per m² can be considered alongside the waterproofing layer, rather than treating the two as separate jobs.

Before the visit, it helps to have a few details ready. Tell us the roof area and how many levels the building has, and note where leaks have appeared and whether they occur after rain or during hot afternoons. Let us know if the roof is in regular use for equipment or foot traffic, and whether the building has any tanks or basement areas that may need attention at the same time. Photos of ceiling stains and the roof surface, along with the age of the existing covering if you know it, will let our surveyor plan the visit properly and give you a clearer scope before any work begins.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

Signs worth paying attention to

The following signs are worth checking before they grow:

• Stains on the top-floor ceiling after rain
• Water pooling on the roof
• The old waterproofing is cracking

Where the problem usually comes from

• Damaged waterproofing around tank and AC bases.
• Wrong falls towards the drains.
• Cracks in the roof slab — we check this before anything else.

Tools and methods, and when we use them

From the first visit to the report

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
