Who checks roof junctions on a Bosaso build?

Roof inspection gaps in Bosaso show up at the junctions: the wall head, the parapet base, the eaves and every penetration. The roof sheet or slab can be sound while water still finds a path at the edge. A clerk of works closes that path by holding the work at fixed points and recording what was seen before the next trade covers it.

Why do roof junctions get missed on Bosaso builds?

Junction work is small, awkward and quickly buried, so it drops off the inspection list first. A parapet base, a wall-head flashing and a pipe penetration each take under an hour to form, and the next trade covers them the same day. When the clerk of works is also tracking deliveries, concrete pours and labour, those short tasks fall between visits. Supervision norms in Puntland often put one person across several sites, which turns inspection into a walk-through rather than a hold point.

A second mechanism is that nobody wrote down what to look at. A general instruction to check the roof gives no trigger for the moment before the screed, tile or sheet goes down. Ask the site supervisor which junction stages are held for inspection and who signs them off. If the answer is verbal, the gap is open. Walk a recently finished roof in the same area and look at the wall head after the first rain; ask the building owner what they saw.

What does a roof inspection gap look like at the wall head?

The defect hides under a neat finish and shows as a damp patch, a stain line or lifted plaster on the inside face. Water sits at the junction and moves sideways through the wall. General practice is to carry the waterproofing or flashing up the wall and over the upstand, with a drip or cover detail that keeps water off the wall face. Confirm the upstand height, the overlap and the fixing method against the project specification and the engineer's detail drawing.

At parapets, the base and the coping are the two check points. At eaves, the check is the gutter line and the first sheet or slab edge. Around pipes and vents, the check is the collar and the seal. For each one, the general sequence is: form the detail, inspect it, photograph it, then allow covering. If the specification calls for a flood test or a water spray test, the engineer sets the duration and the pass mark. Ask for the test record, not a verbal report.

How do you close the gap on the next roof?

Write the hold points into the inspection plan before the roof starts, and give the clerk of works the authority to stop covering work. A workable list for a Bosaso roof: wall-head flashing, parapet base and coping, eaves and gutter, each pipe or vent penetration, and the final roof surface. For each one, name the detail drawing, the check, the person who signs and the record that proves it.

Match the clerk of works to the workload. Where one person covers several sites, agree which junctions must be seen in person and which can be evidenced by a dated photo plus a signed checklist. Ask the contractor to sequence junction work so it is not covered the same day. Where a detail is unclear, put the question to the engineer in writing before the work starts, not after. Regulations and permit requirements vary; ask the municipal engineer's office what it requires for the plot and keep the reply on file.

What to do next

Before the next roof starts, write a one-page junction checklist with five hold points, the sign-off name and the photo required for each. Walk the site with the clerk of works, the contractor and the roofer, and agree each point against the engineer's detail drawing. Then set the first inspection date in writing and hold the covering work until it is signed.
