Is insulation for a warehouse in Najran worth the cost when the air outside is so dry? Many property owners ask this, and the answer depends on how the building is used and how it is built. The centre of Najran sits about 1309 m above sea level, so the city is high and its climate is distinct from the coast. For companies storing goods or running workshops, the building envelope still matters: heat gain through the roof and walls affects working conditions and stock. Our service covers spray foam, XPS boards, liquid roof waterproofing and bitumen membrane, so the right choice depends on what the building needs. Spray foam costs SAR 20–45 per m², XPS boards SAR 12–30 per m², and liquid roof waterproofing SAR 8–25 per m².

Our inspection starts with a walk through the building to note the roof area, wall exposure, existing cracks and any signs of moisture. We check the roof surface for ponding, look at joints and penetrations, and assess whether the walls or slab show cracks that need injection, which is priced at SAR 40–120 per metre. Where storage tanks or water-holding areas are present, we check their interiors as well, since tank internal coating is priced at SAR 25–60 per m². We then measure the areas accurately and record the condition of each surface. From these notes we set out which systems suit each zone and give you a written scope with the ranges that apply to your building.

Before the visit, gather the building plans or any drawings you have, the roof and floor areas if you know them, and a record of past leaks or repairs. Tell us how the space is used, whether it holds stock, machinery or people, and which areas feel hottest or wettest. Clear access to the roof and to any tanks or basements will save time on the day. Please also note any waterproofing work already done, because old membranes can change the method we recommend. With this information ready, the inspection can focus on the problems that matter to your business.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
