I have a metal shingle roof with leaks around the chimney and at a valley. Can you repair this? If not, who do you recommend?

We do work on most types of metal roofing.  We do not however work on Aluminum Shake/Shingle products.  We will be more than happy to take a look at what you have or send a photo to info@brinkmannquality.com with your question and we can respond.
