Two things shape roofing on the North Shore: the age of the housing and the tree canopy over it. Ku-ring-gai, Willoughby, Lane Cove and Mosman hold some of Sydney’s best-preserved Federation and Californian bungalow stock, much of it inside heritage conservation areas where roof form, pitch and material are part of what the listing protects. Ku-ring-gai Council in particular has extensive conservation area coverage, and a re-roof there is a planning conversation as much as a trade one.
The canopy is the other half. Streets lined with mature gums and turpentines drop leaf and bark into valleys and gutters year-round, and shaded southern roof planes hold moisture long enough to grow moss and lichen. Most North Shore leaks we attend trace back to one of those two things rather than to a failed roof.
The classic North Shore leak is a valley that has silently filled with leaf litter, held water against the metal, and rusted through under the tiles. Close behind are cracked and slipped Marseille tiles, ridge capping with perished mortar, and flashings around chimneys on the older Federation homes. We lift tiles and inspect the valley rather than guessing from the ceiling stain, replace corroded valley irons, rebed and repoint capping, and clear the debris load that caused the failure in the first place.
On a heritage-listed or conservation-area property, replacement means matching the original roof rather than modernising it. We source period terracotta profiles and slate to match what is already on the street, keep ridge, gable and eaves detailing intact, and prepare the documentation a council heritage officer will want to see. On post-war and contemporary North Shore homes, where there is no such constraint, we will talk you through terracotta, concrete tile and Colorbond on merit. Removal, disposal and compliant installation are handled either way.
Under this much canopy, maintenance is not optional. Gutters and valleys need clearing at least twice a year on most North Shore properties, and more often where a large gum overhangs the roof. Our visits clear valleys, gutters and downpipes, treat moss and lichen on shaded planes before it lifts tiles, check and repoint capping, and reseal penetrations. Properties on bushfire-prone land get their gutter and valley protection checked at the same time.
Second storeys, rear additions and garden studios are common across the North Shore, and often on steep or heavily treed blocks with difficult access. We work with your builder from framing through sarking to finish, match new roofing to the original where the property sits in a conservation area, and detail the junction between old and new so it does not become the first leak. Access, craneage and tree protection are worked out before we start rather than on the day.
A hundred-year-old Federation roof can have decades left or be a season from failing, and you cannot tell from the driveway. Our reports assess tile and slate condition, valley and flashing corrosion under the tiles, capping and bedding, sarking presence, and the debris load in the drainage system. You get photographs, condition ratings and a clear separation of urgent work from planned maintenance, which is what buyers, sellers and insurers actually need.
Gutters on the North Shore work harder than almost anywhere in Sydney, because they are full of leaf for most of the year. We replace rusted and sagging gutters, correct falls so water actually reaches the downpipe, upsize downpipes where the catchment demands it, and fit quality leaf guard that suits the debris you actually get, since fine she-oak and gum leaf defeat a lot of cheaper mesh. On bushfire-prone properties we fit non-combustible guard with the correct aperture.
Working on century-old terracotta is a different skill from sheeting a new build. Brittle tiles crack underfoot, original valleys are often hand-formed, and the bedding mortar behind a ridge can be sand by now. Our roofers know how to walk and work this stock without creating new damage, how to match a discontinued tile profile, and how to tell a genuinely failed roof from one that needs a good repair and a maintenance plan.
Steep pitches, brittle heritage tile, sloping blocks and mature trees make North Shore roofs demanding to work on safely. Every job is set up with edge protection and anchor points suited to a steep tiled roof, and access is planned around the block rather than forced. Our crew holds working-at-heights certification and we carry full public liability and workers compensation cover.
Matching a Federation roof means having somewhere to get the tiles. We source salvaged and reproduction terracotta in the profiles used across the North Shore, slate, and period-appropriate valley and flashing materials, alongside the full current Colorbond range. Knowing which products a heritage officer will accept saves a lot of time when a conservation-area approval is involved.
On an older tiled roof, the cheapest thing you can do is clear the valleys before they rust through. A rusted valley iron means lifting and re-laying tiles across the whole valley run, which costs many times what a maintenance visit would have. The same logic applies to capping: repointing is a modest job, while a ridge that has let water into the roof space for two winters is not. We are straight with you about which category your roof is in.
Federation homes, Californian bungalows, post-war brick and contemporary builds across the North Shore. Terracotta and slate repairs, valley replacement, rebedding and repointing, full re-roofs in tile or Colorbond, gutter renewal and leaf protection. We work to Australian Standards, match materials properly on heritage properties, and give you a written scope with fixed pricing before anything starts.
Schools, medical suites, offices and strata buildings through Chatswood, St Leonards, Crows Nest and the surrounding centres. We schedule around occupancy, manage access and compliance on buildings that stay open, and work with the metal, membrane and tiled systems these properties use. Strata committees get staged pricing and the documentation they need to get work approved at a general meeting.
Summer storms bring branches down on North Shore roofs, and a heavy limb through brittle terracotta opens a roof up fast. We respond to storm damage, fallen branches, sudden leaks and blocked drainage, make the roof safe, install temporary weatherproofing, and return to complete permanent repairs. Everything is photographed as we go, which makes the insurance claim considerably simpler.
Terracotta dominates the older North Shore streets, much of it Marseille pattern laid before the war and still serviceable if it has been looked after. We replace cracked and slipped tiles with matched profiles, rebed and repoint ridge and hip capping using flexible pointing, replace rusted valley irons, and treat the moss and lichen that shaded southern planes attract. Concrete tile on post-war homes gets the same treatment with different materials.
Colorbond suits North Shore additions, garages, studios and contemporary homes, and it is the sensible choice on bushfire-prone blocks where a non-combustible roof covering is required. It is also considerably lighter than tile, which matters when a roof is going over an existing structure. Where a property sits in a conservation area, we will tell you honestly whether metal will get approval before you commit to it.
Flat and low-slope roofing turns up on North Shore rear additions, garden studios and mid-century homes, and on the pergola and deck roofs that are common on sloping blocks. Under a canopy these are debris traps, so falls and drainage matter even more than usual. We install and repair membrane systems with genuine falls, keep outlets accessible for clearing, and detail upstands and penetrations so they do not become the weak point.
We start with a detailed consultation and roof inspection. Our team reviews your needs, assesses the roof condition, and clearly explains possible solutions.
You’ll receive a transparent proposal with recommended solutions, material options, and a clear timeline — no jargon, just what you need to decide.
Once approved, our licensed team completes the work according to the scheduled timeline. Most roof replacements finish within 3–7 days, with quality and safety at the core.
After finishing, we inspect the roof with you, ensure everything meets expectations, and leave your site spotless. We also share tips for ongoing care.

Tomkat Roofing has spent over twenty years on Sydney roofs, including a great many century-old terracotta roofs under North Shore tree canopy. We are a licensed, insured team and winners of the 2024 and 2025 Australian Small Business Champion Awards in the roofer category.
Every job starts with a proper inspection, including under the tiles where the real problems hide, and ends with a written scope and fixed pricing. If clearing your valleys and repointing the capping will get you another decade, that is what we will recommend.
Signs like leaks, sagging, missing tiles, or water stains often indicate the need for repair. However, if your roof is over 20 years old or has widespread damage, a full replacement may be more cost-effective.
Yes, we are fully licensed and insured, giving you confidence that all work is carried out to Australian standards and safety regulations. Our team is committed to delivering high-quality roofing services.
The timeline depends on the size and complexity of the roof, weather conditions, and the materials used. Most residential roof replacements take between 2 to 5 days. We’ll provide a clear timeline before the work begins.
Absolutely. We stand by the quality of our materials and workmanship. All our roofing work comes with a workmanship guarantee, and we use materials that are backed by manufacturer warranties.
