Roofing Kenya

Cost guide

How much does roofing cost in Kenya?

Roofing cost in Kenya is the total of six things: the material, the structure that carries it, labour, accessories such as flashings, ridge caps and gutters, transport to site, and whatever the site itself demands — access, scaffolding, removal of an old roof. It is calculated from the actual roof area and specification, not from the floor area of the building, which is why a credible figure follows a measurement rather than a phone call.

We do not publish a rate per square metre on this page.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.

Information gain

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.

Read the quotation

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.

Preparation

Quotation preparation checklist

Gather these before you contact any roofer. It shortens the process and makes competing quotations comparable.

01

Project location

Town or site, and how far a delivery vehicle reaches the plot.

02

Building type and stage

New build at wall plate, occupied home, warehouse, house in use.

03

Roof drawings or dimensions

Architecture or structural drawings, if you have them.

04

Roof shape and pitch

Gable, hipped, mono-pitch, flat, or a combination.

05

Existing roof, if any

What it is, its condition, and whether it must be removed.

06

Photographs

The roof from a distance and up close, plus the ceiling below any leak.

07

Scope you want priced

Covering only, or with gutters, fascia, insulation, waterproofing.

08

Material or preference

Or say you want options compared — that is a valid brief.

09

Timeline

When the roof is needed, and any rainy-season constraint.

10

Budget range

Not to spend it, but so the specification proposed is realistic.

Value over price

Why the cheapest quote is not always the cheapest project

A 28-gauge sheet can cost a third less than 30-gauge and look identical on delivery. It dents, drums in rain and rusts faster — the cheapest quote is often a thinner sheet.
