Upside down roofing faster safer easier instead of shingling from the bottom up we re shingling from the top down.
Upside down roof.
Benefits of inverted roofs the great benefit of inverted roofs is that the insulation protects the membrane from extremes of weather such as frost uv exposure and the expansion and contraction that comes about from summer winter temperature cycles which can be as much as 80 c on some roofs.
The so called upside down roof is simply a rearrangement of the normal elements of a roofing system to try and overcome some of the disadvantages of the conventional arrangement.
Also known as a protected membrane or upside down roof inverted roofs employ insulation which can resist water absorption provide excellent thermal performance be unaffected by freeze and thaw cycles withstand surface traffic and be protected from uv and mechanical damage among others.
These systems are typically applied in conditions where there is extensive roof traffic or to protect from excessive weather conditions such as multiple hail events.
Inverted membrane roof systems.
In an inverted membrane system the coventional membrane arrangement is invereted or turned upside down.
