How much does roofing cost in Kenya?
We do not publish a rate per square metre on this page. Any figure quoted without your roof area, pitch, material and site conditions would be a guess, and guesses are what make roofing projects go over budget halfway through.
What follows is the full list of what goes into a roofing cost, so that you can read any quotation — ours or anyone else's — and see what is in it and what is missing.
What makes up the total
Materials + Structural work + Labour + Accessories + Transport + Site requirements
Materials
The covering, its profile and gauge, plus underlay and the 10% waste a cut-up roof really needs.
Structural work
Trusses, purlins and battens in timber or steel, sized for the covering's weight and the span.
Labour
Driven by area, pitch, complexity and height. Hips, valleys and dormers cost more per square than a plain gable.
Accessories
Ridge and hip caps, valleys, closures, sealants, gutters and fixings — the most commonly under-quoted line.
Transport
Distance to site, road condition and sheet lengths. Long spans need a vehicle that carries them intact.
Site requirements
Scaffolding and safe access, working around an occupied building, the weather window and disposal.
Roof area is not floor area
A 120 square metre house does not have 120 square metres of roof. The roof is a set of sloping planes that extend past the walls at the eaves and gables, so its surface is always larger than the footprint beneath it, and the steeper the pitch, the larger the difference. Quantities and labour taken from floor area are therefore short before the first sheet is cut.
Pitch increases the area
The same footprint under a steeper roof has more surface to cover, more structure to carry it and more edge detail to seal.
Overhangs are part of the roof
Eaves and verge overhangs are covered area, and they bring fascia, soffit and gutter into the picture.
Shape drives waste and labour
Every hip, valley, dormer and penetration adds cutting, flashing and time. A simple gable is the cheapest shape to cover.
On top of the geometry, sheets overlap at the side laps and end laps, tiles have an overlap, and cuts at hips and valleys create offcuts that cannot be reused.
Why two houses with the same floor area cost differently
| Variable | House A, simple gable | House B, hipped with dormers |
|---|---|---|
| Roof shape | Two planes, one ridge | Multiple planes, hips, valleys, dormers |
| Roof area vs footprint | Modestly larger | Considerably larger |
| Cutting and waste | Low | High, difficult cuts at every hip and valley |
| Flashing and edge detail | Ridge, eaves, verges | Ridge, hips, valleys, dormer cheeks, penetrations |
| Labour | Fast, repetitive runs | Slower, detail-heavy |
| Structure | Standard spans | More members, more connections |
What gets left out of roofing quotations
The cheapest quotation is often the least complete one. These are the items most often missing, and each one still has to be bought and fitted, so an omission is a deferred cost rather than a saving.
Ridge and hip caps
Priced per metre, and easy to leave off a lump sum.
Valley gutters
Where two slopes meet, the highest-risk detail on the roof.
Wall and apron flashings
Every point where the roof meets a wall or parapet.
Fixings and washers
Correct type and length for the profile and structure.
Profile closures
Fillers at eaves and ridge that keep birds and driven rain out.
Fascia and soffit
What frames the roof edge and closes the ceiling void.
Gutters and downpipes
Including brackets, outlets and where the water discharges.
Structural repairs
Rotten purlins or wall plates found once the old roof is off.
Removal and disposal
Stripping the old covering and carting it away.
Access and safety
Scaffolding, edge protection, ladders and harnesses.
Insulation and ventilation
Cheap during installation, expensive to retrofit.
Penetration detailing
Vents, flues, solar fixings and tank supports.
Quotation preparation checklist
Gather these before you contact any roofer. It shortens the process and makes competing quotations comparable.
Project location
Town or site, and how far a delivery vehicle reaches the plot.
Building type and stage
New build at wall plate, occupied home, warehouse, house in use.
Roof drawings or dimensions
Architecture or structural drawings, if you have them.
Roof shape and pitch
Gable, hipped, mono-pitch, flat, or a combination.
Existing roof, if any
What it is, its condition, and whether it must be removed.
Photographs
The roof from a distance and up close, plus the ceiling below any leak.
Scope you want priced
Covering only, or with gutters, fascia, insulation, waterproofing.
Material or preference
Or say you want options compared — that is a valid brief.
Timeline
When the roof is needed, and any rainy-season constraint.
Budget range
Not to spend it, but so the specification proposed is realistic.
