Picture the owner of a small office block or a commercial complex in Ahad. The building has been standing for years, the staff have grown used to the ceilings, and then one wet season a stain appears on the top floor. Maybe a corridor smells damp, or a tenant calls to say water is dripping near the lift lobby. The owner wants the problem fixed without closing floors for weeks, and wants a clear figure before committing to work on a roof that covers the whole building.
The local facts matter here. The centre of Ahad Almasarihah sits about 667 m above sea level, which places the town on high ground rather than in a low basin, so the roof is exposed to plenty of sun and temperature swings through the day. For an owner, that means the roof membrane is worked hard, and heat-driven movement is a common reason for splits along seams and around roof fixtures. Liquid roof waterproofing is priced at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m², so the choice of system will shape the budget more than anything else. Where the roof is also used for water storage, tank internal coating at SAR 25–60 per m² is a separate line to consider.
A practical sequence helps. First, walk the roof after rain and mark ponding areas, cracks and failed joints, and check the parapets and drains. Second, measure the roof area in square metres so the per-m² ranges can be applied to a real figure. Third, if the roof has cracks, budget for crack injection at SAR 40–120 per metre before any surface work, because a sealed surface over an open crack will fail again. Fourth, decide between a liquid system and a membrane based on access, traffic on the roof and how much downtime the tenants can accept. Fifth, if insulation is part of the upgrade, XPS boards at SAR 12–30 per m² can be included in the same visit. Finally, ask for the scope in writing, with areas, materials and the work sequence listed, so the owner can compare quotes on equal terms.
For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
