Klam Construction is one of those rare contractors who clearly work by the motto of anything worth doing is worth doing right. They replaced a roof on my 1912 home and this job was anything but standard, as we wanted to decommission a chimney, repair aging rafter tails and improve cosmetic touches under the eves. From the get-go I knew that Abel and his company would do a fantastic job. During the bidding process, they were attentive, thorough and followed through. Where other companies bid based on computer images, Abel actually climbed on the roof to see what was needed. The crew itself was fast, courteous, clean and thorough. The cosmetic carpentry work was stellar. They took the time to address the little details that make all the difference both in our home’s appearance and in the quality of the installation itself. I would enthusiastically recommend Klam Construction to anyone seeking a new roof, and especially anyone who values the aesthetic of their home.

I got a lot of other bids prior to choosing Klam Construction and they exceeded my expectations very reasonable and did additional repairs no one told me about for no additional cost.

Klam construction did exactly what they said they would do. with our old house, nothing was going to be easy. all product was delivered when they said it would be and the job was done on time. nothing but praise to this company for their work.

It is prefect, as perfect as you can get as far as what we've seen. Everybody that sees our roof says it is just beautiful, and we couldn't be happier.

Their attention to detail was exemplary. They are one of the few roofing companies I found that were willing and able to do cosmetic carpentry work as well.

I needed my old roof (2+ layers) removed, and a new roof installed (plywood, shingles, vents, flashing). I also needed 2 large skylights installed, which involved removing and reinforcing rafters. The cost I listed includes the price of the skylights.
Abel was always very punctual and professional. His team was courteous and worked hard. They completed everything in two days. The work was done exactly as asked and is clearly of good quality. Abel met with me several times before construction, because I had questions about ventilation and skylight options. He willingly answered my questions and adjusted the scope of work when I shifted my plan. He also met with me after construction to walk through the work and answer any final questions. He and his team were personable, and they clearly care about pleasing the customer. They took extra care to protect my new deck and garden. They pointed out issues that they found (like an ailing chimney) and advised us to keep an eye on it. Also, their labor is guaranteed (as are their roofing products), so they will come and fix anything that isn't quite right in the years to come. Klam's bid was competitive - it was the best relative to the quality we were promised and received.

Tear off and replace the roof from my house and detached garage.

I called four companies for estimates on tearing off the existing roof and re-roofing my house and detached garage. Three returned my call and sent someone to my house to evaluate the job. Abel Serrano, the president of Klam Construction, was the only one to actually provide a written bid. The estimators for the other two companies pointed out some architectural features that would make roofing cumbersome and the fact that it would not be possible to place a drop box next to the house. One of the other estimators told me his company would install ridgetop vents, without actually investigating whether or not they would be appropriate for my house. Abel took me into the attic to investigate the airflow and showed me why rooftop vents would not work. Another estimator told me that his company was already booked until late spring and said that, if anyone bid less than $25,000, and I was comfortable with the company, I should hire them. In other words, of the four companies I contacted, Klam Construction was the only one interested in re-roofing my house and garage. Abel prepared a detailed bid, with diagrams showing what materials would be used in each area and the exact placement of vents. He told me about his experience and the history of Klam Construction. I was impressed with his thoroughness and the fact that he listened to what I wanted. I was also pleasantly surprised that he said Klam could do the job soon. This winter has been unusually cold and snowy, which delayed the beginning somewhat but, when his crew arrived, they worked very hard from dawn until after dark until the job was done. Even though the temperature was 20 degrees, the crew seemed happy, which made me happy too. One of them even whistled while he worked. They cleaned the area at the end of each day, using a magnetic roller to pick up any stray metal and a leaf blower to get rid of the dust. They finished the main part of the job in two days and a few hours, right before the return of the snow. Abel explained that the temperature has to be higher for the material used on the flat part of the roof, so they installed another material in the meantime and will return when the weather is warmer to put on the permanent covering. He said I could pay the final $1000 when that is done. They left my yard cleaner and neater than it was when they started. I’m very happy with Klam Construction and the work they did for me.
