How can I reduce some of the potential disadvantages associated with low slope roofs?
___________________________________________________________________________________________ Low slope roofs are more susceptible on the one hand to water entry due to ice dams and on the other hand to wind-driven rain. Therefore, the key to a successful low slope roof is to increase the water shedding properties of the roof system. Rain and melting snow do not run off quickly on low slope roofs. As a result, the potential for ice dams is increased. IKO recommends three ways to reduce these risks: 1) By providing adequate ventilation the formation of ice dams can be decreased. 2) For the underlay a self-adhesive modified bitumen membrane like Armourbase Premium SA is the best option. 3) Finally, we strongly recommend the use ‘Shield’ bitumen roof shingles, as the self-adhesive underside prevents wind driven rain getting underneath the shingle tabs.
