Roof Inspections and Reports in the Hills District

Three different people ask for a roof report

The homeowner who has a stain on the ceiling, or who has been told by a door-knocker that their roof needs replacing and wants a second opinion before spending five figures.

The buyer about to bid on a large two-storey brick home in Castle Hill, Kellyville or Cherrybrook, where the roof is the most expensive single element on the building and the least visible during a ten-minute open home.

The claimant who needs storm damage documented properly, before anything is moved and before memory replaces evidence.

Those are three different documents. They all start with the same thing: somebody actually getting onto the roof and into the roof space.

What the inspection covers

On the roof:

• Tile condition — cracking, surface breakdown, delamination, slipped and previously patched tiles
• Sheet metal condition — fixings, corrosion, foot traffic damage, flashing laps, sealant doing a flashing's job
• Ridge and hip lines — bedding mortar, pointing condition, displaced caps
• Valleys — debris load, corrosion at the lower end, whether the tiles either side are cut and seated correctly
• Flashings at walls, chimneys, parapets and changed rooflines
• Penetrations — flues, vents, skylights, solar brackets, whirlybirds, aerials
• Gutters, fascia, downpipes and whether the fall actually works
• Leaf guard and valley mesh, and on bushfire-prone blocks whether it is non-combustible

In the roof space:

• Sarking present, absent, torn or perished
• Battens and structural timbers, and whether anything is soft from repeated wetting
• Water tracks and tide marks, which show historical leaks even on a dry day
• Insulation condition, including batts that have been saturated and compressed
• Ventilation, and whether bathroom or rangehood ducting is discharging into the roof space
• Vermin and possum damage, which is common in the heavily treed suburbs and shreds sarking

What you get in writing

• Dated photographs of each defect, taken close enough to be meaningful
• A plain-English description of what has failed and why it has failed
• Findings separated into urgent, monitor, and acceptable
• A scope of works for the repairs, itemised
• Clear statement of anything that could not be inspected and why — a roof plane too steep to walk safely, a sealed roof cavity with no access hatch, a section under a fixed solar array

That last point matters. A report that quietly implies the whole roof was inspected when part of it was unreachable is not useful to anybody.

What the housing stock here means for a pre-purchase read

The Hills District is unusually mixed, and the roof questions change street by street.

1960s to 1980s brick and tile through Winston Hills and older Baulkham Hills: the tiles are usually sound, so the real questions are pointing, bedding, sarking and valley iron. These roofs are frequently candidates for restoration rather than replacement, which is a very different number.

Large two-storey homes in Castle Hill, Kellyville, Glenhaven and West Pennant Hills: complex hip-and-valley roofs with many junctions. The leaks live at the junctions, and access costs real money, so a buyer should know what future maintenance on that roof will involve.

Acreage at Dural, Middle Dural, Kenthurst, Annangrove, Galston and Maraylya: the house roof is often the smaller half. Sheds, stables and verandah runs all need including, and on tank-water properties the roof is also the drinking water catchment, which makes flashing materials and coatings relevant.

New estates at Box Hill, Rouse Hill, North Kellyville and Beaumont Hills: age is not the issue. Workmanship is. On a ten-year-old Colorbond roof the inspection is looking for short flashing laps, fixing problems, unflashed penetrations and gutters with insufficient fall.

Councils, certificates and what we do not do

The district straddles two local government areas. Most of it sits in The Hills Shire, while Cherrybrook, West Pennant Hills, Galston and Middle Dural are in Hornsby Shire — and Castle Hill, Glenhaven and Dural are split across the boundary, so which council applies can depend on which side of a line your block sits on.

For roofing, that matters mainly in three situations: heritage listing, bushfire-prone land, and any change to roof form or pitch rather than a like-for-like replacement. A like-for-like roof replacement is normally treated as maintenance rather than development. Your section 10.7 planning certificate is the document that sets out the constraints on your land.

We are roofers. We do not issue planning advice, BAL certificates, structural engineering reports or pest certificates, and we will tell you when you need one of those instead of us.

Cost

A straightforward inspection and written quote on a house in our service area is free and carries no obligation. Where you need a more detailed standalone report — pre-purchase, insurance documentation, or a report prepared for a third party such as a strata manager — that is quoted up front before anything is booked, because it is a different piece of work with a different output.

Call (02) 9100 0388 and say which of the three situations you are in, or book an inspection.

After the report

Depending on what is found, the next step is usually roof repairs, gutter work, a tile restoration or a replacement. Inspections across Cherrybrook, Castle Hill, Bella Vista and the rest of the suburbs we cover.
