In brief
- Roof insulation only works if the layers stay in order, the boards stay tight, and nothing bridges heat from the sheet to the ceiling.
- Ask the crew to explain the layer order, the fixing pattern and the edge details before any material goes up.
- Check a recent roof the same crew built by looking at the underside and the fascia line, not by asking for references alone.

Roof insulation skills gaps in Burao show up as indoor heat that no thickness of board can fix. A crew can buy the right product and still leave the building hot because the layers sit in the wrong order, the fixings crush the board, or a metal path lets heat cross from the sheet straight into the ceiling. The gap is practical, not academic.
What does the skills gap actually look like on a Burao roof?
The gap shows in the layer order, the fixing pattern and the edge details, not in whether insulation was bought. A roof assembly normally needs the reflective sheet facing the hot side and an air gap kept open, with the board held tight so no joint opens. If the crew lays the foil face down, presses the board flat against the sheet, or bridges the gap with a fixing, the assembly conducts heat instead of reflecting and slowing it. Heat then radiates from the ceiling downwards through the afternoon. Ask the crew to say the layer order out loud before work starts, and to show how the spacing between sheet and board is held. Confirm the required build-up against the project specification and the roofing supplier's written instructions, since products differ.
How does that gap create avoidable indoor heat gain?
Avoidable indoor heat gain happens when heat finds a path the insulation was meant to break. Metal purlins, fixings and unsealed laps all conduct. A single compressed strip at a lap can carry more heat than the surrounding board blocks, and the ceiling below that strip stays warm. On many roof assemblies the effect builds through the day because the sheet radiates downwards. The check is physical: stand under the roof in the afternoon and feel for warm bands that line up with purlins or joints. If the warmth follows structural lines rather than spreading evenly, the assembly is bridged. Ask for the fixing layout and the lap detail in writing, and compare it with the manufacturer's guidance for that board.
How do you detect the gap before and after the work?
Detect it by asking three questions and walking one finished roof. Before work, ask the crew to describe the layer order, the fixing method and how they keep the air gap open at eaves and ridges. Ask which product they will use and request its data sheet. During work, look at a partly laid area and check that boards sit tight, joints are staggered, and no fixing presses the board flat. After work, walk a recent roof the same crew built. Look at the underside for compressed strips, open laps and gaps at the fascia, and ask the owner whether the ceiling still runs warm in the afternoon. For any formal requirement, ask the relevant local authority what records it keeps on roof build-up and inspection.
What to do next
Ask the roofing crew to write the layer order, fixing pattern and edge detail for your roof on one page, then walk a roof they finished in the past year and look at the underside. If the written detail and the finished roof do not match, price the correction before the next sheet goes down. Keep the signed page with your project records.
Frequently asked questions
Can I check roof insulation without special tools?
Yes. Ask for the layer order in writing, inspect a partly laid area, and feel the ceiling underside in mid afternoon for warm bands that follow purlins or joints.
Who should confirm the roof build-up for a Burao project?
The project engineer or architect, checked against the roofing supplier's written instructions. Ask the relevant local authority what records it keeps for inspection.
