Brookvale is the working centre of the Northern Beaches: the largest industrial and commercial area on the peninsula, wrapped around Westfield Warringah Mall, the bus depot, the car dealerships and the printing trade. That mix puts two completely different kinds of roof within a few streets of each other, and they fail in different ways.
The blocks bounded by Pittwater Road, Old Pittwater Road, Cross Street and Winbourne Road carry the densest run of commercial roofing on the peninsula. Retail and light industrial roofs here are almost all low-pitch sheet metal, and almost all draining internally. When one of them backs up, the water has nowhere to go but through the ceiling of a trading business.
Brookvale sits low relative to the ridges either side of it, and stormwater from a large catchment passes through the suburb on its way to the lagoon. That means downpipe and stormwater connections matter more here than the gutter itself: a gutter that drains into a blocked or undersized connection will overflow no matter how clean it is.
Awnings, canopies and roller-door lintels are where commercial roofs in Brookvale actually leak. They are added later, flashed into an existing roof, and the junction between old and new is rarely detailed as well as the original. It is the first place we look on a workshop or a dealership.
Warehouse and workshop roofs in Brookvale are wide, low-pitched sheet metal draining into internal box gutters rather than eaves gutters. A box gutter is a different animal: it has to be designed to AS/NZS 3500.3, and when it overflows the water goes inside the building, not over the edge. Most of the urgent calls we get from Brookvale businesses are box gutters, not roofs.
Away from the industrial blocks, Brookvale is largely mid-century housing with concrete tile or early Colorbond roofs. Both are now at the age where the pointing has gone brittle and the original fasteners have given up, and both are simple to fix now and harder to fix later.
Gutters near the industrial blocks collect a fine, heavy grit that ordinary leaf debris does not. It holds moisture against the base of the gutter and starts corrosion from the inside, so a Brookvale gutter can rust through while looking clear from the ground.
Commercial roof work in Brookvale means working around trading hours, staff and deliveries. We plan access before quoting rather than turning up and finding a truck bay under the only safe set-up point.
Yes. Box gutters, sheet metal roofing, downpipes and stormwater connections on warehouses, workshops and retail. We are fully insured for commercial sites and can work outside trading hours where access needs it.
Fine industrial grit settles in the base of the gutter and holds water against the metal. It never looks blocked, but the gutter corrodes from the inside out. It is the most common thing we find on the industrial side of the suburb.
