My advice to anyone who is considering using this company is to check out their rating at the BBB website. They have an "F" rating with 21 complaints against them.
I would never use this company again. I am still dealing with a leaking flat roof two years after SPEARS applied a Mule Hide coating. After contacting the manufacturers myself, they told me their product was not designed to do what SPEARS guaranteed me it would do! They made several attempts to "patch" the problem by slopping tar on it, and then just started ignoring my calls and emails.
I have filed complaints with the Louisiana Board of Contractors (SPEARS does not possess a contractors license), The BBB, (SPEARS is not a member and would not respond to the complaint) and the Attorney Generals Office (SPEARS either could not be contacted or would not respond) so I am left out $6000 and now have to pay a real roofing company to fix the problem!
