Roof Installation, Done Properly

TreadstoneCPM installs new roofs and replaces old ones across George and the Garden Route. That covers new home builds, full re-roofs on existing homes, commercial roof installations, and specialist roof work where the existing structure needs upgrading before new sheeting or tiles go on.

Every roof install includes engineer-signed trusses where required, proper waterproofing detailing, correct flashings and valleys, and a written workmanship guarantee on the installation — not just the materials.

What a Roof Installation Includes

How a Roof Installation Runs

1. Site visit & measure

We come out, measure the roof, check the structure, and talk through your options — sheeting vs tile, colour, pitch and budget. No charge.

2. Written quote

Line-item quote with fixed price, fixed programme, materials spec, workmanship guarantee and payment schedule. Nothing starts until it’s signed.

3. Install & sign-off

Strip, structural checks, install, flashings and detailing, clean-up, and a written workmanship guarantee handed over on completion.

New Roof or Re-Roof — Two Different Jobs

Roof installation covers two situations that share a name and very little else, and getting clear on which one you are in changes the price, the programme and the risk.

A new roof on a new build starts from an engineered truss design, an A19 certificate for the erected trusses, correct bracing, and a covering specified for the exposure. Everything is visible, everything is new, and the only real variable is whether it is specified properly for a coastal site.

A re-roof on an existing building is a different animal. The covering comes off and whatever is underneath becomes visible for the first time in decades — perished underlay, rotten battens, corroded fixings, rafter ends gone at the eaves, and sometimes truss members that somebody cut to run a cable. A re-roof quote that has not allowed for finding any of that is a quote that will be revised.

The other decision in a re-roof is whether the covering type changes. Going from tile to metal reduces the dead load substantially and is normally the easier direction; going from metal to tile adds weight the trusses were never designed for. Either change needs an engineer’s check, because the load pattern changes even when the total does not.

We price re-roofs with the likely findings identified rather than buried, so the variation conversation happens before the work rather than during it.

What Gets Installed, in Order

A roof is a system and the sequence is not negotiable, because each layer covers the one before it permanently.

Structure. Trusses to the engineer’s design, set out, erected plumb and braced. Bracing is the part most often skimped and the part that resists wind uplift — on the Garden Route it is not optional detail.

Battens or purlins at the centres the covering requires, fixed into the truss members rather than into whatever is convenient.

Underlay. On a tiled roof this is the actual waterproofing layer, and it has to run continuously, lap correctly, and discharge into the gutter rather than behind it. On a sheeted roof it manages condensation as well as incidental water.

Covering, fixed to the manufacturer’s specification for the exposure — gauge, fixing type and fixing centres, with closer fixing at edges and corners where uplift is highest.

Flashings, valleys, ridges and penetrations. Formed in a compatible metal and dressed properly rather than sealed with mastic. This is where the roof leaks or does not.

Rainwater goods, sized for the roof area and the rainfall, with real falls and a discharge point that takes the water away from the building.

Compliance and Handover

A roof on a new home sits inside several compliance frameworks at once, and the paperwork it generates is worth collecting rather than chasing later.

SANS 10400 governs structural performance and weather protection. The A19 certificate is the engineer’s or competent person’s certification of the erected roof structure, and it is a document you want in hand — banks, insurers and conveyancers all ask for it eventually. NHBRC enrolment applies on a new home, and roof leaks arising from workmanship and materials carry their own period of cover under the scheme.

On top of that, the covering manufacturer’s warranty is conditional on installation to their specification — fixing type, fixing centres, coating handling and compatible flashings. A roof installed outside the specification may look identical and carry no material warranty at all.

At handover you should receive the A19, the manufacturer warranty documentation, our written workmanship guarantee, and a short maintenance note setting out what needs checking and how often. On the coast that note is not a formality: clearing gutters and valleys, replacing perished washers as a batch, and an annual look at the flashings is what gets a roof to its design life.

Common Questions

How long does a roof installation take?

A standard single-storey residential roof install runs 5–10 working days, depending on size, complexity and weather. Full re-roofs (strip and replace) add 2–4 days. Commercial and industrial installs depend on scope — the exact programme is in your quote.

Do you install both sheeted and tiled roofs?

Yes. IBR, Kliplok, corrugated and standing seam metal sheeting, plus concrete and fibre-cement tiles (Harvey, Marley and similar). We’ll recommend the right system for your pitch, your budget and the look you want.

Who supplies the materials?

We supply everything under the same contract — trusses, sheeting or tile, flashings, fasteners, insulation and waterproofing. That way if something is wrong, there’s one person accountable, not a supplier-blames-installer situation.

Is the roof install covered by insurance?

We carry public liability and contractors all-risks insurance on our installs, and the manufacturer warranty covers the materials. Your household insurance takes over once the roof is handed over — the installation itself carries our written workmanship guarantee.

Do you handle storm damage and insurance replacements?

Yes. We do insurance-claim roof replacements, condition reports, and work directly with assessors when required. We can supply a full photo report and written scope for the claim.

How long does it take to install a roof?

On a new build, the structure and covering on a normal residential footprint is a matter of days to a couple of weeks depending on complexity, access and weather. A re-roof takes longer because of the strip and because of whatever the strip reveals. The bigger programme point is weather: getting a building weathertight before the wet part of the year is the single most valuable scheduling decision on a Garden Route build.

What is an A19 certificate?

It is the certification of the erected roof structure by a competent person — confirming that the trusses as built match the engineered design and are correctly braced and fixed. You want it in hand at handover rather than six months later, because banks, insurers and conveyancers all ask for it, and reconstructing it after the ceiling is up is considerably harder.

Can I change from tile to metal when re-roofing?

Yes, and it is normally the easier of the two conversions because it reduces the dead load on the trusses substantially. The trusses still need an engineer’s check, because the load pattern changes even where the total load drops, and the pitch has to suit the sheet profile. Going the other way — metal to tile — adds weight the structure was not designed for and needs a much more careful look.

What do you find when you strip an old roof?

Most commonly: perished underlay, corroded fixings, rotten battens, and rafter ends gone at the eaves where a failed gutter has been running down them for years. Occasionally truss members cut by someone running a cable or a pipe. None of that is visible before the covering comes off, which is why we identify the likely findings in the quote rather than pretending a strip is a known quantity.

Does a new roof need approved plans?

A new roof on a new build is part of the approved plans for the building. A like-for-like re-roof on an existing house generally does not need a new submission, but changing the covering type, the pitch, or the roof geometry usually does — and so does anything affecting the structure. If in doubt we check with the local authority before starting rather than after.

Do you guarantee the roof?

Yes — a written workmanship guarantee from us, alongside the covering manufacturer’s warranty on the material. The second one is conditional on installation to their specification, which is one of the practical reasons to care about fixing type and centres: a roof installed outside spec can look identical and carry no material warranty at all.
