Why bitumen membrane differs in Buraydah

Team note on Buraydah: 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.. The centre of Buraydah sits about 606 m above sea level (SRTM open elevation data).

A school owner in Buraydah usually manages a large flat roof that carries the full force of the sun and the occasional sudden downpour. Classrooms, staff rooms and a long corridor of covered walkways all depend on that roof staying dry, and a leak above a learning space is a disruption that families and staff notice quickly. The owner is often balancing budget, term calendars and the need to keep the building in use while work is carried out.

For this property type, the local facts matter in a few clear ways. Buraydah's centre sits about 606 m above sea level, so the city is inland and well above the coast, which means its roofs face strong sunlight and wide temperature swings between day and night. A bitumen membrane is a sensible choice for a broad school roof because it is priced at SAR 15–35 per m², which lets an owner plan the area by area rather than all at once. Liquid roof waterproofing is also listed at SAR 10–25 per m², so it can be compared as an alternative, while crack injection at SAR 40–115 per metre suits isolated defects on an existing surface. For spaces that are not roofs, the bathroom waterproofing rate of SAR 15–40 per m² and the spray foam rate of SAR 25–65 per m² give the owner a clear range to compare within the same building.

A practical sequence keeps the work manageable. First, walk the roof after rain and mark every damp patch, ponding area and visible crack, and note which rooms lie beneath each one. Second, measure the total roof area in square metres so the bitumen membrane range can be applied to a realistic figure. Third, decide which sections need full replacement and which need only crack injection, and schedule the noisier or fume-producing work outside teaching hours. Fourth, ask for the scope to be written per square metre and per metre so that every line can be checked against the ranges above. Finally, inspect each completed area before handing the roof back to the school, and keep a dated record of the work for future maintenance.

For schools, the larger jobs are planned for weekends and holidays.
