Before we start: what we know about Jazan

The centre of Jazan sits about 7 m above sea level (SRTM open elevation data). Jazan is about 1.9 km from the sea coast (OpenStreetMap).

Team note on Jazan: 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..

A roof leak in Jazan most often starts where the waterproofing membrane has aged or cracked, and water finds its way along a seam, a parapet edge or a drain outlet before it shows as a stain on the ceiling below. In a home that has not had a periodic check, the first sign is usually a damp patch after rain that slowly spreads. Catching this early is far cheaper than dealing with a flooded room during an emergency, so a scheduled inspection of the roof surface, its joints and its drains is the most practical step for most households.

The local setting shapes how that inspection should be done. The centre of Jazan sits about 7 m above sea level, so the land is low and rainwater that cannot run off quickly tends to collect on flat roofs and in drainage outlets rather than draining away. Jazan is about 1.9 km from the sea coast, which means the salty, humid air can speed up the deterioration of exposed coatings and sealant joints. An inspector working here should pay close attention to standing water marks, blocked outlets and the condition of edge details, not only the middle of the roof. Where the membrane is worn, a liquid roof waterproofing system is commonly priced at SAR 8–25 per m², while a bitumen membrane falls within SAR 15–35 per m², so the choice between them depends on the roof's condition and the budget you are working with. Where water has already entered a wall or a floor below, the cost picture changes, and spray foam at SAR 20–45 per m² or crack injection at SAR 40–120 per m may be relevant for particular defects.

Before the visit, ask the company to explain exactly what they will inspect and what they will not, including drains, parapets, rooftop fixtures and any water-storage tanks on the roof. Ask whether the price quoted is per square metre and how the roof area will be measured, since the rate ranges above vary with the product and the work required. Ask which materials they propose and why they suit the coastal conditions near Jazan. Finally, ask for a written summary of the findings and a schedule for the next periodic check, so that small faults are recorded and watched rather than forgotten until the next heavy rain.

Preventive checks follow a written schedule instead of waiting for a fault.
