I had a leak on my tile roof that I had paid two other roofing companies to fix. Since it doesn't rain very often I didn't know if the problem was solved until the next rain. Unfortunately, the other two companies didn't offer any guarantee or call back with the repair. I spoke with Discount Roofing and got a free estimate. The estimator assured me the area that was previously repaired by other companies was not the issue and that it stemmed from the air conditioner area and vent on the roof. I waited until this last rain to post this review just to make sure there was no leak. In addition, I also have in writing that it included a service call back if the same area leaked after the repair. The other positive point I want to make is the estimate was half the price I paid the other contractors. So glad I made the right decision on the right company.
