Guaranteed workmanship on your roofing - whether you need an inspection, roof repairs, waterproofing, guttering replacement or a whole new roof
Astern Group Ltd’s Hamilton-based re-roofing and roof repair services start with thorough inspections and end with a 15-year guarantee.
To begin with, we’ll conduct a drone assessment of your roof. Our drone technology makes asset inspections easy. The drone returns all the information we need and then our specialist roofing contractors interpret the footage to produce a full and easy-to-understand report on your roof’s condition.
Whether the solution you need is big or small, from a partial or full resdential re-roofing job on your house, to a leak repair for the roof on a commercial building, or a liquid membrane roofing system installation, Astern Group Ltd can help. We assess the problem, talk you through your options and come back with solutions and a quote to get your work underway. We can also talk about what else we can do in your roof while we’re up there – like adding a skylight, altering roof pitches or roof flashing installation if you’re carrying out building alterations or extensions.
Sort your roofing issues out simply and professionally with Astern Group Ltd. Get in touch with our team for the best roofing services in Waikato and beyond.
Get the right roof fix, first time with help from Astern Group Ltd
If your roof inspection shows minor faults, Astern Group Ltd can assist with rectifying your issues before they become bigger problems. Our commercial and residential roofing experts can:
Replace flashings and rescrew the existing roof sheets where existing screws have lifted or lost their heads. If only small areas are damaged this is a cost-effective option. We can also repair or replace rotten timber supports.
Install new guttering, spouting and downpipes. We can add gutter guards to prevent debris build-up, using industrial grade aluminium protection for commercial buildings and high-quality PVC gutter guards for Hamilton residential properties.
Apply exterior liquid membrane waterproofing systems. We recommend a TPO/Enviroclad product. It’s not glued like Butynol and is heat welded giving a stronger, seamless finish. We also offer tanking services to waterproof your block work areas
Keep out the birds and rodents with fencing and scaring devices. Your building will stay healthy and your food-grade certification intact with our bird proofing, netting and scaring installations or pest-proof fencing.
If your roof has major damage re-roofing may be more cost-effective
If the damage to your roof is extensive, then a total re-roofing may be more cost-effective than trying to carry out repairs.
When re-roofing is the best option, our team can remove the existing roof before installing a new roof and new flashings. If the timber supports or purlins are rotten we’ll replace those at the same time as well as making sure the roof space is free from vermin, birds and insects.
Re-roofing is also a good time to make sure your insulation is up to scratch and our team can install roofing paper or insulation during the process. You can also add skylights or change roof pitches as part of commercial fit outs or home renovations.
Keep your roof in great condition with Astern Group Ltd's building and roof washing services
Once your repair or re-roofing is complete, Astern Group Ltd can help to keep your roof in top condition with regular roof washes using biodegradable cleaning products. For moss and mould we can now send up our drones to do the work. Carrying 10 to 12 kilograms of cleaning fluid they can cover 3000 square metres in one load, so they’re a cost-effective and safe way to get the job done perfectly.
Water blasting and soft wash exterior cleaning are also available or any residential, commercial or industrial premises. We can work on just your roof or the full building, including any outdoor area like driveways, car parks and courtyards.
A regular maintenance programme keeps your site clean, healthy and safe. At the same time, we can keep an eye out for any problems that might be developing.
Our team has worked on plenty of roofing renovations across Waikato and beyond, and are considered roofing specialists by a number of respected clients. To find out how we can make it easy and cost-effective for you, get in touch to make a time for us to talk about suitable roofing solutions.
