Before we start: what we know about Tabuk

The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data). Team note on Tabuk: 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..

Will a clinic roof in Tabuk really need waterproofing, and what does it cost? Tabuk sits about 762 m above sea level, and for a clinic owner the answer depends on the roof's condition, the membrane type, and the area to be covered. Liquid roof waterproofing typically ranges from SAR 10–25 per m², while bitumen membrane runs SAR 15–35 per m² and spray foam SAR 20–45 per m². Insulating boards add another option at SAR 10–30 per m² for XPS boards. Each system suits a different roof, so the right choice is made only after an inspection.

The inspection begins with a walk over the full roof surface to check for ponding, cracked screeds, failed sealant at parapets, and blisters in older membranes. Where cracks show in the structure, crack injection is priced at SAR 40–115 per metre, and the technician measures the length of each crack and marks it for the quote. Drains, outlets and roof edges are checked for blockage and proper falls, because water left standing will defeat any coating. Moisture readings are taken where staining shows below, so the team can tell whether the leak is coming from the roof or from a plumbing line above a treatment room. The findings are then written up with photographs and a line-by-line estimate.

Before the visit, the clinic should clear access to the roof hatch and mark any areas that have leaked in the past, including ceiling stains in consulting rooms or the store. Keep a copy of any previous waterproofing invoice or warranty, since it shows what membrane is already in place. If the clinic has water tanks on the roof, note their size and how long they have been in service, because tank internal coating is priced separately at SAR 25–55 per m². Tell the inspector which rooms are used most, so repairs can be scheduled around patient hours. A short list of these details saves time on the day and makes the estimate more accurate.

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