Frequently asked questions

Whether you need an urgent leak repair, seasonal gutter clearing, or protective treatments for your metal or membrane roof, here is everything you need to know about how we work at Black Sands Roofing.

How much does a roof repair cost?
Depending on the type of call-out, we either provide an immediate hourly call-out repair service or conduct a physical site visit to provide a fixed quote for specific works. We always inspect your roof thoroughly before supplying a final quote.

Do I need to be home for the inspection or repairs?
No, it is not necessary for you to be home for repairs or estimating visits as long as our team has safe access around the perimeter of your property. However, it is always nice to meet you and discuss your roof options face-to-face if you are available.

How long will my roof repair take?
Minor repairs and gutter cleans are typically completed within a few hours on the day. Larger repairs or membrane patching can take from half a day to several days depending on weather conditions, roof pitch, and the overall scope of work.

What damage do lichen and moss actually do to my roof?
Lichen and moss trap moisture against long-run metal and membrane surfaces, speeding up corrosion, lifting laps, and degrading protective factory coatings. Over time, roots can penetrate seals and cause hidden water ingress before leaks become visible indoors.

How often should I have my gutters cleaned?
We recommend having your gutters cleared at least once or twice a year, particularly before the winter rains or if your property is surrounded by trees. Regular clearing prevents overflows into your eaves and protects structural fascia boards.

What precautions are taken if I have a rainwater collection tank?
If your roof collects water into a drinking tank, we disconnect the downpipes before applying any moss, mould, or lichen treatments. We ensure the system is thoroughly flushed after the required dwell time before reconnecting your rainwater supply.

How often should Auckland roofs be washed or treated?
Given Auckland's marine climate, airborne salt spray, and high humidity, we recommend washing and treating your roof at least once every year to prevent corrosion, clear organic growth, and extend the lifespan of your cladding.

Do you provide warranties on your workmanship and materials?
Yes. We stand firmly behind our craft by providing comprehensive workmanship warranties for all our repair and maintenance work, alongside full manufacturer material warranties on all new reroofing installations.
