The rapid rise in popularity can be associated with several of tpo s inherent benefits including.
Tpo roofing installation temperature.
All water based products must be protected from freezing temperatures at all times.
Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope.
It really is too cold when temperatures drop below 40 f 4 c.
In the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989 it s a single ply membrane made from a polymerized combination of polypropylene and ethylene propylene rubber that can be attached to a roof with adhesive or with mechanical fasteners.
Many roofing products have adhesive properties that require the sun s heat for activation.
A ensure that the roof surface is dry.
The best temperature range for roof installations is between 70 and 80 degrees fahrenheit 21 27 degrees celsius but when is it too cold to roof.
Even trace amounts of moisture may cause poor adhesion and lead to moisture entrapment within the roofing system.
Excellent long term heat and uv resistance.
2 install 1 2 fiberboard screwed into the roof with roof screws and 3 plates and densdeck adhered on top with 2 part adhesive.
Heat welded seams provide greater seam strength to taped and other seams.
In general tpo is a relatively low cost high performing roof membrane when installed the right way.
It will allow you to fix all the rotten wood beneath the roof.
Heat welded seams provide superior strength.
The roof substrate must be clean and dry.
According to the 2014 2015 national roofing contractors association nrca market study most new projects in the past few years have specified a white tpo roof.
Do not apply roofing materials during inclement or threatening weather.
Excellent seam strength.
Secure bond technology ensures uniform adhesion coverage across the entire membrane and creates the most powerful bond over the broadest temperature range to significantly widen the installation weather window.
If the roofing job needs to be done immediately due to leaks or wind damage lay a tarp over the damaged section of the roof or install temporary roofing.
1 tear off current roof this is optional but i highly recommend this step.
To get the best results and to prevent breakage or softening of materials install roofing when the temperature is between 50 and 60 degrees f if at all possible.
When the outside temperature is below 40 f 4 c installation of the firestone tpo system requires additional precautionary measures.
The benefits of a tpo roofing system.
Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price.
Both fullforce epdm sa and ultraply tpo sa install in temperatures as low as 20 f 7 c.
Starting with the roof membrane we will work down through the system and.
