    Basa, You should use an elastomeric coating or at least mix some rocks or sand with tar to block UV. The roof would last a lot longer. 3-4 year roof life is ridiculous.

    Dear Kelly,

    You have covered almost all types of roofs. But here in India, there are other types of roofs, one of which is a roof consisting of pre-cast cement slabs, covered with tar felt for waterproofing. Tar felt is roofing felt enriched with bitumen.

    The problem with tar-felt covered roofs is that these require replacement of tar felts every 3/4 years and casting of footing for module mounting structure is difficult. We can cut out the tar felt part and strip to the cement layer, then further covering with tar felt becomes difficult.

    Please suggest a way for this.
