We know that every detail matters when building a barn, installing a roof, or completing a backyard deck or remodeling project. Our amish craftsman and team get the job done right the first time. We use the best materials and will do the work to your satisfaction! From our high quality materials to our overbuilt structures, we are certain each of our clients will love the work we do.

If for any reason you are not satisfied, let us know and we will do what it takes to make it right. The guys did a great job putting on new metal roof, repairing some of the rotten framing and having boards custom milled to match the half round "log siding" in a cabin my grandfather built on the side of a hill in 1963. Jonathan and his crew were swift, efficient, and detail oriented in the recent construction of our 60x100' pole barn. They were open to mid construction add-ons.

A nearly flat or slightly sloped is considered a low-sloped roof. A 2/12 and under pitched roof are low-sloped. Anything above 2/12 is considered steep. Majority of the residential rooftops are considered steep-sloped within the construction industry. Residential roofing or home roof repairs are the hard tasks that need to be done by experts.
I am very pleased in the decision I made to go with JJ Custom Builders LLC. I had them build for me a 20' X 18' pole build with concrete floor including an 8' X 18' lean- to porch. When taking off the old shingles and rotted wood they encountered a bee problem. Someone was sent to get bee spray and the problem was Resolved- the bees still haven't returned.

You can see the quality craftsmanship in the construction of our 24'X 32' Pole Barn in addition to the home repairs from storm damage after a tree fell into our house. Jonathan and his crew were a great to work with . I would highly recommend JJ's Custom Builders.

JJ's built a 14'x14' deck for us and we are very happy with how it turned out. Jonathan was great to work with, very friendly, always fast to respond and easy to communicate with, and proactive. A miscommunication between Jonathan and the on-site crew led to the incorrect placement of our deck initially, but it was immediately addressed, thoroughly corrected, and it now looks even better than we had originally planned. I think this is important to note because issues, errors and delays can inevitably come up in any project. No company can promise perfection. How they handle a customer's concerns

Jonathan worked one on one with me at an incredible value and completed our pole barn on time. He even came back months later for a small leak for no charge and no questions asked! Hope to work with him again in the future.

JJs Custom Builders replaced the wood on our large dock and did an excellent job. Jonathan King and his crew were professional from start to finish. He and his team take great pride in their work, and they are GREAT to work with. Start and finish time as promised. Polite, hard working crew. Job was done neatly and the finished product looks terrific.

While I know there are other great companies to work with, I am positive no one would’ve beaten this companies quality of workmanship...maybe matched, but no one would’ve beaten this crew. They were top notch!! Very pleased with the work that was done. Tough to please as I am very picky, a perfectionist.

The JJ's crew worked together seamlessly. They were very courteous and very skilled carpenters. The family cabin will hopefully not need any more major repairs until my own grand-kids are swinging a hammer!!

The 55 year old corrugated tin roof on our one room schoolhouse home was in dire need of replacement. We were interested in a fairly new product, the steel shingle, resembling cedar shakes. Jonathan showed us Tamko's product, which we chose in a gray. Though this type of roof is on the expensive side, we love the cottage look it gives our home and we shouldn't have to replace it again. The crew was proficient and friendly as they worked. Thank you JJ's Custom Builders for your professional and quality work.
