Roof waterproofing work in Samtah starts with the location itself. The centre of Samtah sits about 61 m above sea level (SRTM open elevation data), and the town is about 22.6 km from the sea coast (OpenStreetMap). Our technicians use these facts to plan how water will drain off a school roof and how much exposure the surface will face. On a flat or low-slope roof, the first check is whether rainwater has a clear route to the outlets, and whether standing water or ponding has already started to damage the existing surface.

Several things are left to the site visit, because they cannot be judged from a distance. A technician will walk the roof and look for cracks, blisters, lifted edges, damaged parapets and failed sealant around pipes and drains. They will confirm the roof's current covering, whether it is a bitumen membrane, a liquid system or insulation boards, and whether any old layers should be removed before new work begins. They will also measure the total area and note access points, safety rails and any plant or equipment that must be lifted or protected. Pricing for each option is set after these checks, using the agreed rates for the chosen system, which may fall anywhere within the published ranges for liquid roof waterproofing (SAR 8–25 per m²), bitumen membrane (SAR 15–35 per m²) or XPS boards (SAR 12–30 per m²).

For the technician, the most useful information is a clear record of the school's roof history. Please note when the roof was last treated, any known leaks and the rooms they affected, and whether the building has water tanks on the roof that may need internal coating (SAR 25–60 per m²). Tell us about any cracks in the parapet or wall edges that may need crack injection (SAR 40–120 per m). Bring the building plans if you have them, and mention whether work must happen during term time, so that noise, access and safety can be planned around the pupils and staff.

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

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

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

The most common causes

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

Tools and methods, and when we use them

The steps in order

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
