My felt roof originally had stone chippings to protect it from the sun, which I removed before I painted it. I Initially use standard bitumin to repair and fill any cracks in the felt, then applied two coats of Solar Reflective Paint. That was 5 years ago, I have just repainted the roof with one coat and there was no further cracking to the felt, which means the paint did its job.
