Frequently Asked Questions
How long does it take to install insulation under an existing metal roof?
Most residential retrofits take a few days, depending on the roof size, access, and whether the sheets need lifting or working from below. A site assessment gives you a firm timeframe.
How do I know if my metal roof needs insulation?
Signs include a home that runs hot in summer and cold in winter, high energy bills, condensation or drips under the roof, and loud rain noise. An inspection confirms what will help most.
Can insulation help with noise reduction under a metal roof?
Yes. Insulation and the right underlay dampen the drumming of rain and the popping of thermal movement, making a metal roof noticeably quieter.
Do the roof sheets have to be removed to retrofit insulation?
Often some sheets are lifted to lay the insulation and underlay correctly, then refixed. In some roofs it can be done from inside the cavity. The right method depends on your roof.
Is retrofitting insulation worth it?
For most Sydney homes, yes. The comfort gain, lower energy costs, and reduced condensation and noise usually justify the work, especially on an uninsulated metal roof.
