                  Will this ladder reach the top of a roof a 2 story home?

                  Answer This Question

                  The maximum open height of this ladder is 21 feet 3 inches and with an extension ladder you need to be at least 7 feet above the highest contact point so you would need to measure your roof to see if this would work using those parameters.

                    The maximum open length of this ladder is 21 ft 3 in and with an extension ladder it should be at least 7 feet above the highest contact point so you will need to measure what your height is needed to get to your roof line.

                                Broken Ladder Known at the Store but shipped Anyways!
                                I bought this ladder and immediately upon delivery I discovered that it arrived damaged. I immediately texted the driver (as I had 30 minutes to do so) and forward a photo identifying my issue. He responded back that he noted this and was instructed by the store to deliver a damaged ladder anyways. I contacted returns and they immediately emailed me and stated a service would pick-up my ladder. Unfortunately, UPS refused to pick this up because it was not packaged, which was in the same state it arrived to me. Therefore, I purchased a ladder, paid for delivery, have a refused shipment, which I have to return myself. Looking at all the damaged ladder complaints, HD is asking to be sued by sending damaged equipment related to working from heights and authorizing this before it arrives. Looking at all the complaints, HD doesn't seem to care about rectifying this. Also, 4 sets of eyes had the opportunity to review this before sending new damaged equipment knowing the customer would not be satisfied. Yet sales over service prevailed. What a clown show! This could have been prevented but sent anyways, HD does not care about its customers, nor does it train its employees to be critical of safety equipment that could hurt its customers, and your web site shows proof that you will be liable because along storied history exists of HD sending damaged ladders.

                                  Solid ladder. You cannot go wrong with Werner products. I also buy the Werner matching attachments. I’m going to continue buying these ladders for my business.

                                  Ladder was delivered with damage to one rung. Ladder appears to be bent.

                                  Defective Rung Lock - Dangerous
                                  Purchased this a year ago, extended this to close to its full length to work on a wall 25 feet in the air and discovered that the ladder would not retract. I found that one of the rung locks was deformed enough that the black plastic gate would not catch on its stop, this caused the rung lock to lock on every rung while trying to lower the ladder. Ultimately had to remove the run lock with the ladder almost fully extended in the air to safely lower it. Ladder also arrived with damage to one rung and one rail significantly out of parallel- this could be due to getting banged up during delivery. Would not recommend,

                                    The email said an adult needed to be present and a signature required. Neither were true. They just dumped it off at my mail box making me carry it 100 yards to my house. When I unwrapped it I discovered that the bottom right leg on the ladder is bent!

                                      Garbage
                                      I bought this from the Home Depot web site because I needed to have it delivered. I wish I had gone to a store, so I would have had better support when I had this problem. My brand new ladder showed up missing the bottom rung. Kind of important to have all the things to step on. Why would the person responsible for shipping something of this size send it in that condition? I’ll never know, but I won’t order anything from this website again that I can’t fit in my vehicle. Trying to get Home Depot’s delivery service to pick up the defective item is still ongoing since they couldn’t get the ladder in the truck when they came to pick it up. The ladder was extended one rung making it a little longer than if fully collapsed, but that was too hard to figure out. It’s still sitting there. This ladder should have been a good fit, maybe you will have better luck.
