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.

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 Al Salmaniyah First District
Roofs on homes in a district like Al Salmaniyah First are usually flat and concrete, and although rain is rare, it finds its way through cracks and joints quickly. A roof often has a parapet, tanks and drains, each a weak spot if not sealed tight. Work begins by preparing the surface and filling cracks, then bitumen rolls are laid and heated until they stick, with special care at the parapet edge, drains and pipes. The roof is checked first to find weakness and old damp.
Al Salmaniyah First District is a district in Al-Ahsa governorate in the Eastern Province, close to Al Muhammadiyah District, Al Salmaniyah Second District and Ayn Najm District.
Sealing needs the most care at the parapet and drain joints, because water pools there first.

Questions about Bitumen roof waterproofing in Al Salmaniyah First District
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.
The roof is checked for cracks, joints, soundness of the parapet and drains, and for old damp stains, because bitumen is laid on a clean, dry surface free of structural weakness.
Tell them if you see damp stains on the ceiling or top-floor walls, whether heavy rain has come before, and whether the roof has tanks or pipes, and send a photo of the roof on WhatsApp if you can.
