Maximum Slope For Epdm Roofing

The rubbergard max epdm membrane is an internally reinforced cured single ply roofing membrane that is designed to combat roof tears and punctures and provides superior resistance to wind forces.

Maximum slope for epdm roofing.

The main component of the roofing system is the firestone rubbergard membrane a tough flexible epdm ethylene propylene diene terpolymer based sheet which is fully vulcanized to provide excellent dimensional stability and weathering resistance. The epdm ethylene propylene diene terpolymer single ply rubber roofing membrane has been an appealing choice of the low slope commercial roofing industry for over 40 years. Ballasted systems are limited to a maximum slope of 2 inches per foot 2 percent. Adhered systems using fire retarded sheets can meet code at virtually any slope to vertical.

Grumpy chicago gutters chicago roofing. System that uses large epdm panels. The following table provides the minimum required allowable roof slope for each type of roofing material mentioned in the code.

In order to achieve this drop a slightly steeper angle of 1 40 1 44 should be the aim when installing a flat roof as this accounts for surface deviations and material deflection among other things.

For example some epdm membrane assemblies have maximum roof slope limitations as low as 1 2 12. Some tpo membrane assemblies also have relatively low maximum roof slope limitations. With the rubbergard r m a.
