Single Ply V Hot Melt
Do you know the difference between Single Ply and Hot Melt Roofing?
We have put together a guide which explains the two.
When choosing a new roof for your commercial property, there are several things to consider, including the local weather conditions, the style of the property and the longevity of the roofing materials. Two popular commercial roofing choices are the single ply roof, and the hot melt roof.
So, what are these two roofing types, and what are the differences?
· A single ply roof involves a single sheet of roofing material that is fully waterproof, weatherproof and UV resistant
· Hot melt roofing involves applying a waterproof membrane in the form of a hot liquid, directly onto a prepared roof or structural deck.
Read on to further understand the differences, the comparisons, and advantages of the two.
Humidity
Why could humidity be a problem for your flat roof?
High humidity increases the risk of condensation occurring. Essentially, as the warm air rises, and meets the colder air at the top of the building, the water vapour in this air will reach its dew point and turn back into a liquid.
The more water vapour there is, the more potential condensation can occur. This can cause a number of issues, including:
· Rotting wooden timber joists and structural frames
· Mould build-up
· Internal leaks
· Deterioration of fixings
For high humidity environments, such as swimming pools, sports halls, large commercial kitchens, and other areas with obvious high humidity, additional measures will need to be taken, these include:
· High performance metal lined vapour control layer
· Using a fully adhered single ply installation method instead of a mechanically fastened system
· Changing carbon fixings to stainless steel fixings
· Inclusion of air conditioning/ventilation
