We come to your property to inspect your roof, determine what are the job requirements and associated costs.
After finding the best time for you, we get straight to work! For roof repair or maintenance, you can trust our expertise.
Two reasons, and they compound. Eucalypt leaf is oily and rots slowly, so it forms a dense mat instead of washing through, and the salt air off the ocean corrodes the metal underneath that wet mat. Homes under gums or Norfolk pines often need clearing three times a year, where an inland Sydney house gets by on two.
They help. In bushfire-prone streets a metal mesh guard stops embers landing in dry leaf litter inside the gutter, which is one of the most common ways homes ignite. It is not a substitute for a bushfire plan, but on a bush-edge property at Belrose, Oxford Falls or Elanora Heights it is a sensible layer, and it cuts your cleaning down to a light service every year or two.
Yes. Steep blocks and high-set homes are normal on the Mona Vale, and we bring the access equipment for it rather than balancing a ladder on a slope. Seaforth, Killarney Heights, Balgowlah Heights and Clontarf are regular work for us. If the access is genuinely difficult we will tell you at the quote, not on the day.

Mona Vale runs from the beach and the ocean pool back across the golf course and up onto the headland. Within a couple of streets you go from full salt exposure to sheltered, tree-lined blocks, and a roof on one side of that line needs different treatment from a roof on the other.
The stretch from Mona Vale Beach north past The Basin towards Bungan takes the full northeasterly. Roofs facing that way get the salt and the driving rain together, which is a harder combination than either alone.
Blocks backing onto the golf course and the reserves carry mature planting right up to the roofline. That is shade, damp and constant leaf drop, which is why moss and lichen on the tiles is common a few streets from a beachfront roof that has none.
A lot of Mona Vale housing started as a modest beach house and grew by extension. Every extension adds a roof junction, and roof junctions are where leaks live. On a house that has been added to twice, the original roof is rarely the problem.
Roofs facing the beach and The Basin take airborne salt every day, not just in storms. Fasteners, gutter brackets and the cut edges of sheeting corrode years earlier here than on a comparable roof a kilometre inland, and the failure always starts at the fixings, not the sheet.
The blocks backing onto the golf course and the reserves have the opposite problem. Little salt, but heavy seasonal leaf fall straight into the gutters, and enough shade to keep moss and lichen growing on the tiles year-round.
On coastal roofs the wash is not cosmetic. Rinsing salt off the roof and out of the gutters is what slows the corrosion, and most Colorbond warranties assume that surfaces not washed by rain get washed by someone. The sheltered parts of a roof, under eaves and behind gutters, are exactly the parts rain never reaches.
A north-east blow puts driving rain onto the exact face of the roof that faces the water. Flashings and laps that hold up all year fail in that one direction, which is why Mona Vale leaks so often turn out to be intermittent.
The sheeting itself usually lasts. The fasteners, brackets and cut edges are what go early, and on a beachfront roof they can need attention in half the time of an inland one. Replacing fasteners is far cheaper than replacing a roof, which is the whole argument for checking them.
Yes, the whole northern stretch of the peninsula. Mona Vale is central to it, so a job here usually gets scheduled quickly.

Australian standards and Code requirements we work to, with the source for each.
The Code requires downpipes to sit as close as practical to where valley gutters discharge. On roofs with several valleys feeding one length of gutter, a downpipe in the wrong position overloads that section long before the rest of the run fills.
The National Construction Code allows a single downpipe to serve no more than 12 metres of eaves gutter. Long unbroken runs on Sydney terraces and wide Federation frontages often sit over that limit, which is why they overflow in heavy rain even when the gutter is clean.
Observatory Hill has averaged around 1,213 mm of rain a year on records kept since 1858. A 150 square metre roof therefore sends roughly 180,000 litres a year through its gutters and downpipes, which is why a blockage shows up as overflow so quickly.
Quoting mona vale in the Northern Beaches is not the same job as quoting it elsewhere in Sydney. Colorbond warranty asks for a six monthly wash: The standard warranty requires fresh water washing at least every six months of any roof area rain does not wash naturally, and does not cover failure… That is the kind of detail that changes the materials, the timing and the paperwork on a roof in Manly or the streets around it. Everything below links to the council or standard it comes from, so you can check it yourself.
The standard warranty requires fresh water washing at least every six months of any roof area rain does not wash naturally, and does not cover failure to replace corroded fasteners. On a coastal home that means eaves, awnings and wall abutments need washing deliberately.

Source: NSW Rural Fire ServiceBlueScope names Manly Beach as its metropolitan example of a surf marine environment, the harshest of its three salt classes under AS 4312. Wind, shelter and areas the rain never washes push the real corrosivity higher still, which is why the steel grade used here is not the one used inland.
Source: BlueScope Technical Bulletin TB-35 and AS 4312:2019Class 3 fasteners are only acceptable beyond 1km from marine influence. From 200m to 1km Class 4 is required, and inside 200m even Class 4 is not enough without checking with the supplier. Most of the ocean strip sits inside that band, so standard screws rust out long before the sheeting does.
