In the 1990’s, this type of roof was very popular for its insulation capabilities and ability to solve transitional problems between incompatible roofing materials. It is a seamless roofing system.
Pros: It has an insulation value of R7 per inch, and it is a quick installation.
Cons: It requires a recoat every 5 -7 years, birds can peck holes into it easily, exposing the foam and speeding deterioration, it is easily susceptible to hail damage. All in all, we give this type of roof system a 5 out of 10 stars.
Our roof techs found an excessive amount of pigeon waste on top of this foam roof. The chemicals in that waste actually eats right through the protective elastomeric coating on the roof, damaging it. It now needs to be completely replaced.
This foam roof is badly damaged, and must be completely re-roofed. A much better alternative to foam roofing is Duro-Last– which requires ZERO maintenance and ZERO recoats for the life of the roof. Also, it is cost comparable to Foam, because we are able to lay Duro-Last directly over the old foam roof, saving the costs of tearing off the old roof
