Removing the Old Covering
Removing the existing covering, collecting the material, and hauling it away in line with waste management requirements.
Removing the old covering and installing a new covering, membrane, and battens on an existing, technically sound roof structure - without unnecessary rebuilding of the structure itself.
Roof covering replacement is the right fit when the roof structure - the rafters, the battens beneath, or at least their load-bearing part - is in good technical condition, but the covering itself has worn out, been damaged, or simply no longer looks the way you want. This page covers only the replacement of the outer covering and the layers directly tied to it. It's also a more cost-effective choice than full replacement when the structure genuinely doesn't need attention.
If the structure is in good shape and you just need a new covering - this is your page. If the assessment finds that the rafters, insulation, or ventilation system also need replacing, we carry out that work as part of a full roof replacement, where the structure is assessed and rebuilt together with the covering.
This distinction matters financially too - there's no point paying to rebuild the whole structure if it isn't necessary, but it's equally wrong to lay a new covering over a damaged or poorly ventilated structure just to save money in the short term. That's why we base the covering-replacement-versus-full-replacement decision on a visual inspection of the structure and, if needed, a timber moisture check - not on defaulting to the more expensive option.
Spending money on a full structural replacement when it isn't needed makes no sense - but putting off covering replacement for too long can eventually create problems that reach the structure too.
Slate has become brittle, metal has lost its coating, tiles are cracking - the covering no longer performs its protective function fully.
Renovating the facade or raising a property's value often includes refreshing the visual appearance of the roof covering too.
For example, moving from asbestos-free slate to a metal roof or standing seam - a new material often needs a different batten spacing too.
Removing the existing covering, collecting the material, and hauling it away in line with waste management requirements.
After the covering is removed - inspecting the exposed rafters and battens to confirm the structure is genuinely fit for continued use.
If the existing breather membrane is aged or damaged, we replace it so the new covering sits on proper waterproofing.
Batten spacing is adjusted to the new covering material's technical requirements - often different from the previous material's spacing.
Installing the chosen material to the manufacturer's specification, including correct overlaps and fastener placement.
Renewing flashing details, ridge elements, and eaves finishing to match the new covering.
The covering replacement process only touches the top layers - the core of the structure stays as it is.
| Layer | During covering replacement |
|---|---|
| Load-bearing structure (rafters) | Stays - only visually inspected |
| Insulation (if present) | Left undisturbed if there are no visible signs of damage |
| Breather membrane | Renewed if aged or damaged |
| Counter-battens / ventilation gap | Checked, renewed as needed |
| Battens | Replaced to match the new material's requirements |
| Covering | Fully replaced with the new material |
If we find timber damage, insufficient ventilation, or aged insulation during the assessment, we'll tell you honestly and recommend switching to a full roof replacement instead of masking the problem under a new covering. That's also why we always insist on an in-person assessment before preparing a quote - an accurate read on the structure's condition simply isn't possible remotely from photos.
Covering replacement is often a chance to choose a more durable or lower-maintenance material than what you had before.

Profiled sheet metal or standing seam - a lightweight, weather-resistant covering that installs relatively quickly.

Clay or concrete tiles - a classic look with a long service life, a popular choice for older-home renovations.

These points can't simply be "covered over" with the new material - each one needs an individual approach depending on the technical properties of the chosen covering.
We assess the condition of the existing covering and structure, and confirm the structure is sound.
We prepare an itemized quote and help you choose the most suitable covering.
Removing the old covering and battens, hauling the material away.
Renewing the membrane as needed, installing new battens.
Laying the covering, fitting ridge and eaves elements.
Quality control, site clean-up, warranty documents.
After removal, we photograph the structure's condition before installing the new covering - confirmation that the decision to replace the covering (rather than do a full replacement) was justified. After the new covering is laid, we check fastener density, overlaps, and detail execution before cleaning up the site and handing over the project.
The cost of covering replacement is mainly affected by the roof area, the new material you choose, the complexity of removing the old covering, and the number of details. If the new material needs a different batten spacing than the previous one, that also affects the overall quote. For an average single-family home, work usually takes 3-7 working days. See our pricing page for exact price factors.
We provide a written warranty for the removal and installation work, while material warranties are set by the manufacturer. See full terms on our warranty page.
On a project in Mārupe, the owner wanted to replace an aged asbestos-free slate covering with a metal roof. During the assessment, we confirmed that the rafters and batten base were dry and technically sound - so we carried out the work as a covering replacement, keeping the existing structure and only renewing the membrane and installing new battens spaced correctly for the metal covering. Total work on this project took five working days. See more completed projects on our projects page.
Covering replacement only touches the outer covering, membrane, and battens - the structure stays as it is. Full replacement also inspects and, if needed, replaces the rafters, insulation, and ventilation system if the structure has aged or been damaged.
We determine this during a free site assessment - checking the condition of the rafters, timber moisture, and the existing ventilation solution. If the structure is dry and technically sound, covering replacement is enough. If we find damage or insufficient ventilation, we'll recommend a full replacement instead.
Usually not - for covering replacement, we remove the old covering and battens down to the membrane or rafters, check their condition, and only then install new battens and covering. This ensures the new covering is fixed correctly and the ventilation gap is right.
The old covering and materials are collected and hauled away in line with waste management requirements. We keep the site tidy throughout the work and after it's finished.
For an average single-family home, covering replacement usually takes 3-7 working days depending on roof area, shape, and the chosen material. We give an exact timeline in the quote after the site assessment.
We'll come out, assess the existing covering and structure, and prepare a clear quote for the new covering.
