Will a clinic roof in Alrass need waterproofing, and what will it cost? Alrass sits about 695 m above sea level at the centre, and for a clinic owner the first question is usually how to protect the roof without disrupting patients and staff. The answer depends on the roof surface and the method chosen. Liquid roof waterproofing is priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m². Spray foam, at SAR 20–45 per m², is another option for certain surfaces. Each method has its own price range, so the right choice comes down to what the inspection finds.

The inspection starts with a walk over the whole roof to check the surface, drainage points, parapets, and joints where the roof meets walls or equipment. Any cracks are noted, since crack injection is priced at SAR 40–120 per metre and is used where a crack runs through the surface rather than across it. The inspector also checks whether any water has already reached the rooms below, because this affects how far the repair needs to go. Measurements of the roof area are taken so the quote can be worked out per square metre. Where a rooftop water tank sits on the roof, its interior condition is noted as well, since tank internal coating is priced at SAR 25–60 per m² and is handled separately from the roof itself.

Before the visit, it helps to gather a few things. Collect the roof plans or any earlier drawings showing the roof area and drainage layout. Note the dates and locations of past leaks, including whether they happened after heavy rain. Let the clinic manager know which days the roof is accessible, and arrange for the rooms beneath to be cleared of sensitive equipment if access is needed. If a rooftop tank exists, have its age and any previous cleaning or repair records ready. With this information on hand, the inspector can give a clearer picture of the work required and a price that reflects the actual condition of your clinic's roof.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

When do you need roof waterproofing?

The following signs are worth checking before they grow:

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

Causes we see in the field

• A common cause: cracks in the roof slab.
• Wrong falls towards the drains — we check this before anything else.
• A common cause: damaged waterproofing around tank and AC bases.
