Questions & Answers


I would like to use corotherm to re-roof an old wooden green house. Please advise on whether there are ridge elements available that can allow use on pitched roofs?


Unfortunately they do not supply a pre made ridge piece as mainly used for lean to roofs this material. 


Want to use the corotherm for two patio covers, intention is to a small one for the shed and then a larger one for the back of our bungalow. Both frames will be in timber with a gable roof - so two questions 1. Do you do anything to cap the gable apex and 2. If I supply the dimenions are you able to supply a complete kit


I am afraid there is not a pre made trim for capping the apex so you you need to find a solution to that. But if you wanted to email plans to sales@roofingsuperstore.co.uk we can assist with quoting the other items.


How do you connect two sheets together?


You use a Glazing bar to join them, please see linked below.



Are your measurements in the dropdown L x W?


Yes correct the measurement in the drop down menu are Length x Width.


can it be cut to fit my metal framed greenhouse and do I need special fixings to attach it to metal fame?


You could cut it but not special fixings are available to fix to metal so you woul need to find another solution for this.


Do you supply any fittings/strips to join multiple roof sheets to stop leakage?


Yes indeed there are Glazing bars to join them side by side but nothing to join end to end. You can find these on the link below.


If you needed help putting together a quote please send us the dimensions and a rough drawing of the project to sales@roofingsuperstore.co.uk.


Can you confirm that the length measurement is the longest part of the sheet when the lines are vertical?


Yes correct, the length runs in the same direction of the flutes of the sheet, down the fall of the roof.


Whats the miniumum pitch this can be installed at?


The minimum pitch is 5 degrees.
