The roof does not appear to leak, but is quite old and has a couple of big 'bubbles' on it. Some areas still have chippings. I would like to extend its life but am not sure what to use; I've seen bitumen based coatings (cheap) or acrylic (very expensive) What is the best thing to use? How should I treat the bubbles? The roof is about 10 sq.m. Thanks in advance for any advice. Peter
