Bedding and Pointing, and Why They Are Not the Same Thing

Bedding is the mortar that the ridge capping tiles sit on, and Australian Standard AS 2050 covers the installation of roof tiles including how capping is bedded and pointed. It is structural in the sense that it holds the capping in position. On an Adelaide roof of thirty years or more it has usually cracked, partly crumbled and separated from the tiles beneath after decades of expansion and contraction. Pointing is the flexible compound applied over the bedding along the visible edge.

Nothing else about the quote matters as much. Roofing work of this kind rewards a contractor who has seen the same situation many times before. Roofs on comparable Adelaide housing behave much the same way, which is why local experience counts here. Contractors differ on how they present this in a quote.

It seals the joint and accommodates movement, and modern flexible pointing compounds perform considerably better than the cement mortar used on older roofs. Local roofers see this constantly across the older suburbs. That accounts for essentially the whole of the difference between the two approaches. A contractor who has restored several hundred Adelaide roofs will have encountered every version of this and can usually say within a few minutes on the roof which category yours falls into, which is precisely the expertise a quoting visit is meant to deliver. The answer shapes what the finished job will look like in five years in place of on handover day. None of it is complicated once somebody has walked you through the reasoning on your own roof.

The distinction matters because a contractor can repoint without rebedding. That means applying fresh pointing over bedding that has already failed, which looks correct from the ground and leaves the underlying problem untouched. Opinions differ among contractors on how best to handle it. That single figure tells you most of what you need. Householders who ask this early tend to end up with quotes they can actually compare side by side. A householder who understands the distinction is in a far better position to judge competing quotes.

Roofing contractors around Adelaide differ on this more than you might assume. A roof of this vintage seldom presents cleanly, and how a quote allows for that is telling. Operators who restore roofs weekly around Adelaide encounter exactly this, and the ones who volunteer an explanation tend to be the ones whose figures hold once the work begins. That becomes most apparent on the older housing across the inner and middle suburbs, where decades of seasonal movement on reactive ground have left roofs that no standard method quite fits and where judgement has to substitute for a checklist. A contractor comfortable explaining the reasoning is generally one who has thought the job through. Contractors who work carefully tend to volunteer this and not wait for the question.

Rebedding involves lifting the capping tiles off, removing the old mortar and laying a fresh bed. It is slow, skilled work and it explains why a thorough restoration costs what it does on an older roof. Asking how many lineal metres are being rebedded against repointed separates quotes immediately. Everything downstream follows from it. Getting a clear answer here removes most of the uncertainty from the rest of the conversation. The practical effect appears over years rather than weeks, which is what makes it easy to overlook.

A roof with badly failed bedding needs the capping lifted, and a quote that only mentions pointing on such a roof is pricing a different job. Raising the point at enquiry stage costs a household nothing at all. Asking the question during the quoting visit costs a household precisely nothing. Households comparing several quotes will find this accounts for more of the variation between them than any other single item, which is a good reason to put the same question to each contractor and compare the answers as against the totals. How a quote treats this item is a reasonable proxy for how carefully the rest was prepared. Putting the same question to every contractor makes the comparison considerably more meaningful.

Reactive Adelaide clay contributes to bedding failure more than most owners realise. Seasonal ground movement transmits through the structure into the roof, and cement bedding that cannot flex responds by cracking. Ridge work sits at tile roofing. Few other items in the quote carry comparable weight. The distinction is easy to miss from ground level and obvious to anybody standing on the ridge.

Valley irons are the other genuine structural item and they are often excluded. The metal valleys where two roof planes meet carry a great deal of water, they corrode from the underside, and replacing them at $400 to $1,200 each is real work rather than cosmetic. Anyone who restores roofs across Adelaide will have an immediate view on it, and a quote that has considered the question reads quite differently from one that has simply priced a coating and a few days of labour. Somebody who has worked through hundreds of these roofs recognises the variations quickly and can place yours within a few minutes of getting up there, which is exactly what a quoting visit ought to be buying. Once explained, most households find it changes which quote they were leaning toward.

When Restoration Is Worth It and When It Is Not

Restoration suits a structurally sound roof that looks tired and has localised faults. Concrete tiles in reasonable condition with failed ridge bedding, some broken tiles and a faded surface are the textbook case, and a restoration genuinely adds years. It does not suit a roof with widespread tile failure. That one figure conveys most of what a householder needs to know. It is the kind of thing an experienced roofer raises in the first five minutes on site.

Once a large proportion of tiles are cracked, delaminating or have lost their surface entirely, coating them seals the appearance without addressing that the tiles themselves are finished. Longer established operators tend to raise this unprompted, which itself says something useful. Adelaide roofs endure enough thermal movement and ultraviolet exposure across a year that decisions which look marginal at quoting stage tend to resolve themselves visibly within a handful of summers, one way or the other. It shows up most clearly on inner and middle suburb housing, where years of seasonal ground movement have produced roofs that resist any standard method and where experience has to fill the gap. Two contractors looking at the same roof will frequently reach different conclusions on it.

Sarking is the consideration most owners have never heard of and it decides a lot. Older Adelaide tile roofs commonly have no sarking, which is the membrane beneath the tiles that catches wind driven rain and dust, and a restoration cannot add it because that requires lifting every tile. Written quotes rarely spell it out unless a householder asks. The remainder of the specification follows from that decision. Clarifying it upfront prevents the sort of variation that sours an otherwise sound job.

Anybody who has been onto the roof will raise the point already. Most households come to this the hard way, some seasons later. The final invoice reflects that decision fairly directly. Anyone weighing several quotes will find this explains more of the spread than anything else on the page, which argues for asking each contractor the same thing and weighing the answers rather than the bottom lines. Anybody quoting without going onto the roof is unlikely to have assessed it properly at all.

A reroof at $15,000 to $45,000 replaces the tiles or sheeting entirely and allows sarking, new battens where needed and modern flashings. It costs several times a restoration and it resets the clock not extending it. Reroof scope sits at roof repairs. Persistent leaks that have already been chased are a signal to stop restoring. A roof that has had repeated repairs and still admits water, the problem is usually systemic instead of a matter of surface condition. Older housing complicates it further, since roofs that have shifted seasonally on reactive clay for decades rarely present the clean geometry a standard method assumes, and working with that takes judgement rather than a checklist.

Timber condition in the roof space justifies itself checking before committing either way. Battens and rafters that have been wet repeatedly may be compromised, and that is a structural question and not a surface one. Framing scope sits at roof framing. An independent inspection before deciding is cheap insurance on a large spend. Across the life of the coating that difference accumulates into something substantial. None of this is unusual on housing of the relevant vintage, and a contractor who has worked through a few hundred of these roofs will have a settled view on how to handle it before being asked the question.

Somebody with no interest in selling either a restoration or a reroof will tell you which the roof needs, and on a borderline roof that advice makes sense its fee several times over. Inspection scope sits at roof inspection. Settling it before anybody is on the roof is worthwhile. The question rarely reaches a quote unless the householder puts it. Ask directly and the answer usually comes back without hesitation. There is not much more to the distinction than that, once it is laid out plainly.

Concrete, Terracotta and Knowing Which You Have

Concrete tiles are the most common restoration candidate across Adelaide's post war suburbs. They accept coating well, they fade rather than fail, and a sound concrete tile roof is the situation restoration was designed for. Concrete tiles lose their surface coating over decades and become porous. That is what produces the chalky faded appearance, and a primer followed by a proper coating system genuinely restores water shedding as well as colour. Roofs here take enough heat and movement across a year that a marginal decision at quoting stage resolves itself visibly within a few summers. Contractors restoring roofs across the metropolitan area encounter this constantly, and the ones who explain it unprompted are generally the ones whose quotes hold together when the work starts and the roof turns out to be much as they described.

Terracotta is fired clay and behaves entirely differently. It does not fade in the same way, it lasts considerably longer, and its glazed surface rejects coatings, which is why the restoration package changes on a terracotta roof. The consequence surfaces at the first heavy autumn rain. Not many owners think to ask before the work is booked. Anyone restoring roofs locally has seen this many times over. There is no cost to putting the question while a contractor is still quoting.

Telling them apart is straightforward once you know. Terracotta is orange through its full thickness and rings when tapped, while concrete is grey inside with a surface layer and sounds dull. Matching replacement tiles is harder on old profiles regardless of material. Many Adelaide profiles are long out of production, and a contractor sourcing secondhand matching tiles is doing genuine work that belongs in the quote. At this age a roof seldom presents cleanly, and how a contractor allows for that separates the quotes.

Older tiles are brittle and break during any work on the roof. An allowance for breakage is normal and honest, and a quote with no tile allowance is either optimistic or planning to charge extra later. Cleaning scope sits at roof cleaning. Painting rather than restoring is a separate service and sometimes the right one. Putting the question before booking costs nothing and settles it early.

Where a roof needs nothing but colour, roof painting alone costs less than a full restoration package. Painting scope sits at roof painting. Not many households raise the point when seeking quotes. Beyond thirty years the difference becomes pronounced. Established operators volunteer this without being pressed, which is itself a useful signal about who you are dealing with.

Metal Roof Restoration

Metal roofs, whether original galvanised or later Colorbond and Zincalume sheeting rolled by Lysaght or Stramit, restore differently and the work centres on corrosion in preference to mortar. Cleaning, treating rust, replacing badly affected sheets and applying a coating system is the sequence, and there is no bedding or pointing involved. Surface preparation determines whether a metal coating lasts. Rust that is painted over continues underneath, so mechanical removal and a rust converting primer are what separate a lasting job from one that bubbles within two years. Households usually find this out once the work is done.

Urgent faults are dealt with at emergency roof repairs. Fasteners are the most common failure point on an older metal roof. Screws and their rubber washers degrade under South Australian ultraviolet exposure, and replacing them is inexpensive work that prevents a great many leaks. Most owners understand this only once the job is underway. The difference compounds across the life of the coating, so a decision that looks minor at quoting stage is not.

Older galvanised roofs respond well to restoration where the sheeting is sound. Coating extends the life of sheeting that has surface corrosion but retains its section, and it is considerably cheaper than resheeting. Metal scope sits at metal roofing. Coated steel roofing is a different proposition and often needs less. A direct question here generally gets a straight answer.

Modern prepainted sheeting generally fails at fasteners, flashings and cut edges rather than across the sheet, so targeted repair usually beats a full recoat. Colorbond scope sits at colorbond roofing. Past thirty years the question weighs more heavily. Two quotes that look close often diverge on exactly this. Adelaide roofs cycle through enough heat and movement that shortcuts here surface faster than they would in a milder climate.

Coastal metal roofs deteriorate faster and need appropriate specification. Salt exposure from the gulf attacks cut edges, fasteners and any breach in the coating, and a restoration there should use products rated for a marine environment. Gutters and downpipes are usually assessed at the same time. They corrode on a similar timeline to the roof, and doing them while access equipment is already in place saves a second mobilisation. Gutter scope sits at gutter replacement. The practical upshot for a household weighing options is that the cheapest quote is routinely the one that has left this out, and establishing whether it is included costs nothing beyond one direct question at enquiry.

Wash Water, Stormwater and the Neighbours

A roof wash produces a considerable volume of dirty water and it has to go somewhere. Moss, lichen, the crusty grey green growth that colonises shaded tiles,, accumulated dust, bird residue and any treatment chemicals all end up in that runoff, and where it discharges matters. Stormwater is not the appropriate destination for chemical laden runoff. South Australian stormwater discharges to watercourses and the gulf, and contractors are expected to manage wash water over let everything flow into the street. Roofers working your suburb will recognise the pattern immediately.

Routine washing is covered at roof cleaning. Moss and lichen treatments are the usual chemical involved. They are applied before or during cleaning, and a responsible contractor manages the runoff, protects garden beds and warns a household about pets and edible plants. The point deserves raising even where it seems a small one. Roofs of this age rarely present cleanly, and the allowance made for that is where careful quoting shows itself.

Neighbours deserve warning before a high pressure clean. Overspray travels, and washing on a windy Adelaide day puts dirty water over a neighbouring car, washing line or outdoor area. Rainwater tanks need isolating before any roof work. A household collecting drinking water from the roof must divert the first flush after cleaning and coating, and a contractor who does not raise this has not thought it through. Environmental obligations sit with the EPA. Adelaide conditions sharpen the consequence, because a shortcut that merely shortens coating life elsewhere shows up here within a few summers of ultraviolet exposure and thermal cycling.

Ventilation fitted at ridge level needs the same care, covered at roof ventilation. Solar panels complicate both the cleaning and the coating. Panels shade roof area, they cannot be walked on, and overspray onto panels reduces their output, so they need protecting or the work sequenced around them. Roofing contractors around Adelaide take noticeably different positions here. That assessment separates a considered quote from a rate applied to a floor area.

What gets answered moves the final figure. It belongs in the quote as against surfacing afterwards. One answer here can redirect the entire recommendation. Supplying that context lets a contractor price the job properly.

Warranties, Contractors and What You Are Actually Buying

Roof restoration warranties are commonly quoted at ten or fifteen years and the number means less than it appears. What matters is what is covered, who stands behind it and whether the business is likely to exist when you need it. A product warranty from a coating manufacturer covers the coating rather than the workmanship. It typically responds to premature failure of the product itself, not to a coating that failed because the surface was inadequately prepared.

A workmanship warranty from the contractor is the more useful one and the less durable. It is worth exactly as much as the business behind it, and roof restoration has a high rate of businesses appearing and disappearing. Where two quotes diverge, this is frequently the cause. Most roofers will give a straight answer when asked directly.

Check how long the business has traded and whether it is a registered entity. A fifteen year warranty from an operator two years old is a statement of intent in preference to a financial instrument. Door knocking is common in this trade and deserves caution. Unsolicited approaches claiming to have noticed a problem from the street, offering a discount for an immediate decision, are a recognised pattern and the pressure to decide quickly is the warning sign.

Deposits should be modest and progress payments tied to stages. A large upfront deposit on a job measured in days is a risk, and consumer protections apply regardless of what a contract says. Contractor obligations sit with Consumer and Business Services and guarantees with the ACCC. Contractors diverge on this more than a headline price suggests.

Regional Considerations Across South Australia

Metropolitan Adelaide has the widest choice of contractors and the most competitive pricing. Roof type varies systematically across the suburbs, which affects what a restoration involves more than location does. Inner suburbs carry terracotta on steep pitches with heritage considerations. That combination makes restoration a cleaning, repair and repointing exercise and not a coating one, and the steep pitch adds access cost.

Post war and mid century suburbs are concrete tile territory and the core restoration market. Moderate pitches, standard profiles and tiles that genuinely benefit from recoating make these the straightforward jobs. Roofers vary on how they handle this part of the job. Where a contractor stands on this generally becomes clear within the first conversation about the job.

The Adelaide Hills adds tree debris, higher moisture and more moss and lichen growth. Roofs there need cleaning more often, shaded roofs deteriorate differently, and bushfire considerations affect gutters and roof detail in designated areas. Coastal properties face salt attack on metal components. Valley irons, flashings, fasteners and gutters all corrode faster near the gulf, and specification there matters more than on an inland roof.

What Roof Restoration Costs

Concrete tile restoration runs $3,500 to $8,000 for a typical Adelaide house. Roof area, pitch, how much rebedding is needed and how many tiles need replacing account for most of the range. Terracotta at $4,000 to $9,500 costs more despite involving no coating. The work is cleaning, tile replacement and thorough rebedding and repointing, and terracotta roofs tend to be older, steeper and more fragile to work on. Metal roof restoration at $4,000 to $10,000 depends heavily on corrosion extent. Surface rust on sound sheeting restores economically, while widespread perforation means resheeting rather than coating.

A high pressure clean alone at $600 to $1,800 justifies itself considering as maintenance. For a roof in reasonable condition carrying moss or lichen growth, cleaning without the rest of the package addresses the actual issue. Rebedding and repointing alone at $1,800 to $4,500 is often the right job. On a sound roof whose ridge capping has failed, that work addresses the leak risk without paying for a coating the roof does not need. A full reroof at $15,000 to $45,000 is the comparison worth running on a marginal roof. It costs several times a restoration, it allows sarking to be added, and on a roof with widespread tile failure it is the cheaper option across twenty years.

What to Look Out For

Ask how many lineal metres of ridge are being rebedded rather than only repointed. Pointing applied over failed bedding looks correct and leaves the actual problem in place, and this single question separates thorough quotes from cosmetic ones. Be cautious about any proposal to coat a terracotta roof. Coatings adhere poorly to glazed clay, they flake within a few years, and they trap moisture in a tile designed to breathe. Require identification of any fibre cement before cleaning on a pre 1990 property. High pressure cleaning asbestos sheeting releases fibres and is prohibited work not a judgement call.

Treat unsolicited door knocking with scepticism, particularly where a discount depends on deciding immediately. Seek your own quotes from contractors you approached instead of ones who approached you. Check the business history behind a long warranty and keep deposits modest. A fifteen year workmanship warranty is worth whatever the business behind it is worth, and disputes have a pathway through SACAT.

How to Get Useful Quotes

Name the roofing material and give the approximate age of the house. Concrete tile, terracotta, galvanised steel and prepainted sheeting each lead to a different scope, and the era indicates what to expect from the bedding. Give the approximate floor area and the number of storeys. Roof area follows from floor area reasonably well, and storeys and pitch determine the access arrangements and much of the labour. Describe any known problems rather than only the appearance. Leaks, cracked tiles, sagging, dust in the roof space or previous repairs each change what a contractor should be quoting.

Mention solar panels, skylights and any roof mounted equipment. Each constrains the work, needs protecting from overspray and affects the sequence. Note whether you collect rainwater. Tanks need isolating before cleaning and coating, and a first flush diversion afterwards is standard practice a contractor should raise unprompted. Have each quote itemise the rebedding metres, the tile allowance, the primer and coating products and coats, what is excluded, and both warranties. Pin down those five and the quotes become comparable, and gutter work sits at roof and gutter plumbing.
