  After repairing my roof Grandmark Roofers left a large gap in the tiles of my roof. I called to ask them about it and was told the project manager would contact me. He/she never contacted me. EDIT Grandmark called me and scheduled an inspection. The inspector found some minor issues and sent out a crew the next day to repair them. Foof looks much better now. Thank you Grandmark.

  I don't often write reviews but I want to credit Eduardo for doing such a thorough and professional job in handling our roof repair project, and Mckay for further help after we accepted the initial bid. Grandmark had the winning bid due entirely to Eduardo's thorough work. We had three different roofing companies visit. All were well rated and we liked all the contractors we met. Two visited both the attic and the roof and one just looked at the roof. Eduardo visited the roof and attic and discovered issues that the other two did not. Eduardo spent more time than anyone else, going back and forth between the attic and roof to identify the source of leaks that he saw (stains in the attic) but that had not yet come through to the inside of the house. We knew we had a problem over the garage (mold + water stains along a seam of wall board). Eduardo found another line of stains that was closer to the house; his video was proof of a wider problem (all three contractors showed videos that were very helpful). Eduardo's discovery led to the initial bid by Grandmark being higher. We didn't want to spend more money, but the evidence Eduardo showed indicated that we'd have to get the additional work done (a few years ago we went with the lowest bidder on another roof repair; they fixed two problems but left one unresolved that later turned into a larger issue). In the end, we actually got more for our money from Grandmark, thanks to Mckay. Two other companies also suggested a roof/tile cleaning, but when Mckay came out to discuss the bid, he looked at the roof yet again and offered to not only lift tile and clean out debris but also lay down ice and water barriers for all the other the valleys on our roof that were not the source of the current problems. He offered to do it at cost for $1,400. Mckay didn't know this but at that point we already had bids of ca. $1,200 for "roof cleaning" but those bids did not include new ice and water shields in the remaining valleys, and might not have even involved lifting tile; one bid, for $1,200, seemed to only involve using a leaf blower. Needless to say, Mckay's offer was an excellent one and we agreed. Looking back on another competing bid, the total was nearly the same as Grandmark's but offered a lot less in terms of repairs and cleaning. So the "highest" bidder was actually the most cost effective. Thank you Eduardo and Mckay. We appreciate your help.
