Roof waterproofing in Alula: before summer & rain season

Before we start: what we know about Alula

The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Main roads in or near Alula: King Abdullah Road.

Roof waterproofing in Alula most often fails at the joints, parapets and drainage outlets rather than across the open roof surface. Heat cycles through the day and night cause small cracks to open and close, and once water gets under the coating it can sit unseen until a leak shows up inside the home. For many houses, the first sign is a damp patch on a ceiling after the first heavy rain, which is why an inspection before summer and before the rain season makes sense.

Alula sits at roughly 697 m above sea level, which means the air is cooler and the nights can feel sharper than in the coastal cities. That shift in temperature adds stress to roof coatings, so surfaces that are cured and bonded properly hold up better over time. Because the area is elevated and dry for most of the year, the usual approach is to focus on flexible liquid roof waterproofing or a bitumen membrane where the roof has regular movement, and to seal crack lines before any new layer goes on. Where a roof is used for water storage or has a tank on it, the inside of the tank may also need a suitable coating, which is a separate job with its own scope.

Before the visit, ask the provider to walk the roof with you and point out the areas they plan to treat, including parapets, edges and drain points. Ask them to explain which system they recommend and why it suits your roof, and to give you a written breakdown of the work, the area measured in square metres and the price per square metre for each element. Confirm how the crack repairs will be priced, since crack injection is charged per metre. Finally, ask how the surface should be prepared, what you need to clear from the roof, and when the work can be done so it is finished before the rain season begins.

Checks before summer and before the rain season catch problems while they are still small.

When do you need roof waterproofing?

If you notice one of these signs in Alula, it is a good moment to talk to the team:

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

The most common causes

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

Tools we use in Alula

From the first visit to the report

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.
