What bitumen roof waterproofing includes
- Checking the roof surface and identifying points that need extra preparation before the rolls go down
- Cleaning the surface and removing failing layers and dirt that would weaken the bond
- Laying bitumen rolls with enough overlap at every seam between one strip and the next
- Sealing the roll edges at the parapet on both the horizontal and vertical faces
- Treating the specific points around drain bases, pipes and AC unit stands
- Confirming the layer is continuous with no break from the centre to every edge

Preparing the surface first
The job starts by cleaning the surface of dirt and failing layers, because a roll only bonds well to a clean, sound base.
- 3
Laying and overlapping the rolls
The rolls are laid in parallel strips and each strip overlaps the next at the edge, because the seam between two strips is the most vulnerable point in any bitumen covering.
- 4
Sealing the edges and penetrations
The membrane edges are sealed at the parapet and around every drain base, pipe and AC stand, because these specific points are where water most often enters.

The service in At Tuhaymiyah
Flat roofs in a small settlement like At Tuhaymiyah usually have tanks, drains and a parapet, and all these spots are open to water seeping in when it rains or a tank leaks. The team checks the concrete surface to see its state and where cracks and joints are, then prepares it by cleaning and smoothing any raised parts, so bitumen rolls stick firmly and form a barrier that moisture cannot breach. The first inspection decides what must be done to treat any weakness before the rolls are laid.
At Tuhaymiyah is a small settlement in Al-Ahsa governorate in the Eastern Province, close to Al 'Uthmaniyah, Udhailiyah and Imam Muhammed Ibn Saud Islamic University District.
Water pools first around the parapet, at corners and along joints, so that is where inspection and care focus before bitumen is applied.

Questions about Bitumen roof waterproofing in At Tuhaymiyah
Bitumen rolls suit flat concrete roofs in most cases. A very sloped roof or one finished with tiles needs a different assessment. The surface should be sound and free of deep cracking before the rolls go down; otherwise it needs extra preparation first.
The middle of the roof is usually flat and continuous. At the parapet, the horizontal membrane meets the vertical wall, forming a joint that moves with heat expansion and contraction. If that edge is not sealed well, water usually finds its way in there.
Clean, sound concrete usually needs a primer coat to open its pores and improve how the roll bonds to it. Laying a roll on an unprepared surface weakens the bond and leaves the layer prone to separating over time, especially with the temperature range.
The seam between two strips breaks the continuity of the waterproof layer. If the strips do not overlap enough and the edge is not pressed down until it bonds, a fine gap remains. That gap opens in summer heat and closes again, and water finds its way through it in every rainfall.
Bitumen suits a flat concrete roof that lets water in and needs a flexible protective layer that handles thermal expansion. If the problem is mainly heat with no visible water entry, another material may be more suitable. An initial assessment of the roof is what determines the right choice.
If you see damp patches on ceilings below, or water seeping from around the tank or parapet, the roof needs inspection and waterproofing. Bitumen stops water passing through the concrete and along joints.
Say where you see damp and whether water comes from a known spot like a tank or parapet, send a photo of the wet area, and mention if the roof carries heavy items.
