HOW WE SUPPLY OUR PRODUCT

All our roofs come supplied with 130mm foil-backed insulation, pre -cut, to meet the 0.15 standard U-value requirement. We believe that by choosing to install the premium, most lightweight replacement roof available in the industry, it should be made to the highest standard without the need for insulated plasterboard and extra weight and depth added to the roof. Finished with 12.5mm foil-backed plasterboard (supplied at additional cost on request) you are ensuring you maintain the fastest possible install time with the least amount of potential problems.

All our roofs come supplied with White Fascia, Gutter, Downpipe and Trims. Fascia is sent in full lengths to be cut and adapted on site.


Gutters are supplied with a running outlet (not spigot) and all variable angles if required. One length of 2.5m downpipe, 2 clips & 1 shoe are supplied with every running outlet point.


All other connections will be the responsibility of installer, subject to their site requirements.


Alternative colours are available at additional cost. When submitting a final survey please note the colour required in order to ensure your quote is accurate.
