Flat roofs (gravel and bitaman) and shingled roofs, require tar to seal cracks or slips to penetrations and bar areas on the roof's surface. If you're looking for a more high quality choice, the alumaseal has the aluminum pigment for increasing reflectivity and UV protection to a roofs substrate roof paint.
When leaks occur with metal roofs, a repair that we offer is resealing all penetrations and areas where sealant has been applied before. Along with that, we replace loose or broken screws with new rubber seals. During this time we can remove and replace rain caps and pipes, if needed.
