Is a roof in Sharurah worth waterproofing before you buy or take over a property? Yes, and the reasons are practical. The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data), so the town is high, dry and exposed to strong sun and sudden downpours that can test a roof's seals. Before you sign, you should know what the roof needs, what it will cost to fix, and whether the previous owner kept it in good condition. Liquid roof waterproofing typically falls in the range of SAR 8–25 per m², while bitumen membrane sits at SAR 15–35 per m², so the roof surface alone can be a meaningful line item in your budget.

A useful inspection starts from the outside and works inward. Walk the full roof surface and look for cracks, blistering, bare patches and places where water has pooled. Check the edges, parapets and joints where the roof meets walls, since these are the most common leak points. Crack injection is priced per metre, at SAR 40–120 per m, so count every visible crack and estimate its length. Inside the building, look at ceilings and top-floor walls for stains, peeling paint or damp smells, and check whether any water tanks on the roof have internal coatings. Tank internal coating is priced at SAR 25–60 per m², so ask when the tank was last serviced. If the property has a basement, note that basement waterproofing runs at SAR 50–150 per m², which shows how costs can build quickly if several areas need work.

Before the inspection visit, gather whatever records exist, including previous repair invoices, warranties and any earlier waterproofing contracts. Note the roof area in square metres, since most quotes are calculated per m², and sketch the layout so the inspector can measure quickly. Mark any known leaks or problem spots and take dated photos after the last rain so the condition is clear. Ask the seller whether the roof has been resurfaced and when. Having these details ready lets you compare quotes fairly and negotiate with confidence before you complete the purchase or handover.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Signs worth paying attention to

The following signs are worth checking before they grow:

• The old waterproofing is cracking
• Stains on the top-floor ceiling after rain
• Water pooling on the roof

Where the problem usually comes from

• Cracks in the roof slab.
• Damaged waterproofing around tank and AC bases — we check this before anything else.
• A common cause: wrong falls towards the drains.
