I did not want to leave the office today without sending this note of appreciation.  We are not quite a full month from the time we first spoke and my roof has been installed and that includes several days because of a rain delay.   From the sales and administrative side of things you and you’re your staff have been superb and professional.   In terms of the actual roof replacement, the crew wasted no time in removal and replacement.  They came ready to work and quickly went into action.   Frankly, I was also impressed  with how they protected the ground surface area and cleaned up afterwards.   It is like nothing ever happened.  Thanks again!

This letter is to say what a  wonderful job you all have done. You all have installed new windows, a beautiful front door with side panels and siding to my home a year or so ago. Since you all have completed such a wonderful job we decided to have you install a brand new roof.

The house looks wonderful, we have so many neighbors, family and friends asked who did the work. I will make sure I refer them to Libery Windows and Siding. I feel like I have the best looking house in the neighborhood.

W. & P. Harvey     Ellicott City, MD

We wanted to take this opportunity to thank you for the outstanding job your company did in replacing the roof and siding on our house. The very same day the work was completed, one of our neighbors came by to compliment us on how good our roof looked. The first question she asked was, “Who did your roof?” What a good feeling to get an unbiased opinion.  As happy as we were about the quality of the workmanship, the professionalism in which the work crew went about performing their work, pointing out the differences in the quality of the shingles they were using on our house versus one of our neighbors, who had replaced his roof only months earlier, and the care in which they went about performing the clean up after the work was completed, the care and professionalism you displayed toward us before we even signed the contract was truly appreciated.

After sustaining the damage to our roof and siding during Hurricane Sandy, it was traumatic to see your most valuable investment in need of major repairs. But the work you did, on our behalf, with our insurance company and the valuable information you passed along concerning how the process worked, we will be forever grateful. But the one thing that stood out the most in my mind was that you never gave us a “hard sell”.  We’d gotten four estimates, for replacement/repairs, before we spoke with you. Not a single one came even close in price, quality or warranties. But the hard sell was evident in each case. In this day and age it’s hard to get one of the three; however, you delivered on all three.   By the way, your 50 year, transferrable warranty is off the charts! If you ever need a reference, you know who to call. Thanks again!

I just wanted to let you know how happy I am with my new roof.  My neighbor recommended Liberty Windows & Siding, Inc to me because he was so happy with the new roof that you recently installed on his house.  You responded immediately by visiting me and presenting a detailed and complete written estimate.  I was also very pleased that you handled all the coordination with the homeowners association and you obtained the required approvals.  Our neighborhood has detailed rules and limitations on what types of exterior changes can be made to our homes, and requires approval for any exterior work, including a new roof.

The new roof was installed 4 days later, so less than a week after your initial visit I had a brand new roof.  I could not believe how fast the crew was able to remove and dispose of my old roof, replace the damaged wood, install the new roof, and clean up.  I have already recommended Liberty Windows & Siding, Inc to another neighbor who expressed an interest after watching your crew at work.   Thank you again for your timeliness and professionalism.

It’s been more than two months since you all installed my new roof and I am writing to say thank you for your service.  I was hesitant at first in making the decision to have a new roof installed and knew it needed to be done.  Your friendly service and job well done made me feel comfortable in knowing I selected the right company. I found the crew to be professional in their workmanship along with their work ethic in making sure the job was completed by working until dusk.  I was very happy when the job was completed.  Thanks again for a job well done.

New Owens Corning TruDef Design Series Roofing
Daryl G.   Ellicott City, MD

I want to commend your workers for the quick efficient and careful removal and installation of new roofing at my residence.  It was amazing to see how each worker instinctively knew what to do and all worked compatibly to complete the job quickly and on schedule.  The Owens Corning 50 year fiberglass architectural Duration try-definition series creates a beautiful appearance and very much resembles wood shakes in style and color giving my home a very “up-scale” sophisticated look.  In my search for a roofing company I went “online” to find five roofing companies in the Ellicott City area and each was interviewed and asked to submit a proposal with price quote and shingle brand.

One submitted a spread-sheet with part numbers and no description and no brand selection.  Another submitted a 20 point proposal recommending IKO architectural 50 year shingles and a second choice of Owens-Corning fiberglass 50 year- the same shingle that you provided-but his price was over two thousand dollars more.  His proposal was second to your proposal that detailed 26 points of installation detail and follow through.  Another proposal didn’t even mention valley and ice shields and when questioned his response was: “oh everyone knows that they are included.”

But I wanted a written detailed proposal like what Liberty provided in a very professional detailed listing point by point regarding what the customer should expect.  Another issue was shingle quality. All things considered, Liberty is at the head of the class with product quality, proposal detail, attractiveness of product and fair and reasonable pricing.  As Owner of Liberty I have no doubt you will have a long, successful tenure leading an excellent company.

Amy G.    Mays Chapel, MD

On very short notice we needed to have our roof done and we were lucky enough to have found Liberty.  They had already done several other homes in the neighborhood so they were already familiar with our HOA rules and standards.  Peter Deily was extremely nice and quick to assess the problem.  I had talked to a few other companies prior with no luck and Mr Deily gave us an excellent price; much less than the others.  Our job was scheduled less than a week later and done before noon.   The contractors were very respectful and quick!  That afternoon, Mr Deily stopped by to examine the job as well as answer a few follow-up questions I had.  Having to have any kind of work done on the home is very stressful and I cannot say how easy this was to have done.

I just want to thank you and your company for doing such an awesome job on my new roof installation.  The crew arrived on time and was finished in a timely manner.  They surprised me by how quickly yet efficiently they finished the job.  They even noticed my chimney needed a side covering and provided me with one.  The crew was very professional and cleaned up when the job was completed.  This is the second project that I had your company complete for me.   Back in the fall of 2011, you completed a window and sliding glass door installation for me.  The crew did such a wonderful job; I knew I had to use them again for the roof installation.  My father recently had a roof installation as well.  I told him, if you want quality work at a great cost, go with Liberty Windows and Siding!   I appreciate all the work that you have done for me and look forward to using you for future projects.

We are very pleased with your professional services.  We feel that the cost quoted was reasonable.  After we signed the contract to have our roof replaced, the work was done within seven days.  The workers came early and completed the job in one day.  They were diligent and worked hard in 90 degree temperatures.  My husband went on the roof to inspect it after completion of the work, and he was very satisfied.  We will highly recommend your company to anyone who is in need of home improvement work.  Thank you for a job well done!

Peter was very professional and courteous during his three visits to my home. He took interest in what I was asking and listened to my every question. He took notice of our three dogs and made sure his crew took extra care to make sure my backyard was cleaned up with extra care. His crew were knowledgable and professional. That were on-time and went right to work. The foreman made contact with us before, during, and after the work was done. They made care not be be overly loud and took great care with the debris both during the project and during the clean up. Great company.

He called me to thank me for the business. He took before, during and after pictures. He called me days after completion to find out out how satisfied I was. I will be replacing my windows soon and will definitely use them.

I bought a brand new home in 2000.  I decided to get a deck so I called Peter.  We discuss things and he gave me a good price.  The deck was beautiful, I was completely satisfied.  Its 2012 now, unfortunately I need a new roof.  I had several estimates done.  I thought about Peter.  I heard his advertisement on Heaven 600, so I call him.  He set up a date and time for him to come over to discuss things with me.  He gave me a thorough explanation of what was going to be done, also he showed me the material he was going to use.  He explained the damages on my roof.  He also said they would clean up everything.  It is surely a blessing to know someone like Peter.  WHat’s in your heart and how you deal with people will take you a long way.  I am sure God has blessed you as well.  When I came home from work, took a look at the roof it was terrific, but the best part is that I have a fifty year warranty on materials.  Thanks Peter.  May God keep and bless you continually.  Thank you for your services.

I would recommend Peter Deily and the Liberty Windows & Siding, Inc to my family and friends who may need work done in their home.  When I contacted them they came right out and gave us an estimate of what needed to be done and how they would do it.  Mr Deily was very polite and explained everything that they were going to do.  He explained about the materials they would be using and the value.  Even as women my sister and I were able to understand what the project would entail.  Mr Deily explained that the materials that they would be using would be delivered the day before they were to begin working; and it was.  They began working at the time they said they would and did a wonderful job.  The whole experience of having our roof fixed was very rewarding and satisfying.   Mr Deily said they would remove any debris that they caused and they did.  My sister and I have nothing but praises for the job they did for us.
