Wisconsin’s winters are long, harsh, and expensive when your home isn’t properly insulated. Too much heat escapes through the attic, driving up energy bills and putting extra strain on your furnace.

At J&B Construction, a trusted Milwaukee roofing and exterior remodeling company with nearly 70 years and three generations of experience, we know exactly how much of a difference attic insulation makes and the benefits it offers.

Lower Energy Bills

Up to 20% of your heating and cooling costs can be saved when your attic is insulated to Wisconsin’s recommended R-values. Less wasted energy means more money in your pocket.

Year-Round Comfort

Attic insulation evens out temperatures across your home, solving the “too hot upstairs, too cold downstairs” problem many Wisconsin homeowners face.

Cleaner Indoor Air

Sealing leaks and insulating your attic helps block dust, pollen, and outdoor pollutants, while also reducing moisture that can lead to mold growth.

Noise Reduction

Insulation absorbs sound, creating a quieter home by reducing traffic, wind, and storm noise.

Protects Your Roof

Proper attic insulation and ventilation help prevent ice dams, a common Wisconsin roofing issue that damages shingles, gutters, and ceilings.

Boosts Home Value

Energy efficiency is a top priority for buyers. A well-insulated attic makes your home more attractive in a competitive market.

How J&B Handles Attic Insulation

We install Owens Corning blown-in insulation — fiberglass or cellulose — designed to fill every gap and achieve the high R-values required for Wisconsin homes. Our process includes:

Assessment: We inspect current insulation, ventilation, and air leaks.
Air Sealing: Gaps around plumbing, wiring, and penetrations are sealed.
Installation: Insulation is evenly blown across the attic for full coverage.
Final Check: We verify depth, ensure ventilation is clear, and leave the space clean.

Unlike companies that only add insulation, J&B understands how roofing, ventilation, and attic systems work together, ensuring lasting comfort and performance.

Why Choose J&B Construction

Not all attic insulation contractors in Milwaukee bring the same level of expertise. With J&B, you get:

Nearly 70 years of service to southeastern Wisconsin homeowners.
140+ years of combined staff experience in roofing and remodeling.
GAF Master Elite Contractor certification, ensuring the highest standards.
Customer-first service with clear communication and respect for your home.

“In Wisconsin winters, every bit of heat you lose through the attic has to be paid for in fuel or electricity. Our trained installation teams know how to seal, insulate, and ventilate correctly so your home holds heat like it’s supposed to.”

The only complaint I have is when I have J&B do my roof in another 30 years or so, is Dave their sales man (a great guy) would not guaranty I could get the same great crew I had this time. They did a fantastic job. Much better than the last roofing company did. A nice bunch of guys. Did a very nice job cleaning up. I'd give them 10 stars but 5 is the limit. If you need a roof done this is the company you want to do it. One more point I need to make. The guys that did the chimney flashing are artists. I went up on the roof when they were done and was very pleased with not only the roofing job but the sculptured sheet metal work. It's kind of a shame it's on the roof and not hanging on the family room wall :). You get the point. Hire em. You'll like em.

We live in a historic designated neighborhood and recently had our 30 year wood shingle roof replaced with another wood roof and new gutters. From Day 1 of the project to the final day, the entire team was responsive, professional, and very competent. When some minor changes were proposed by us they quickly and effortlessly complied. After going through this experience with J&B, I would highly recommend them to anyone considering a roof and gutter replacement, whether it be a simple or complicated project.

J & B did an amazing job from start to finish. The initial meeting at my home took place exactly at the time that was agreed upon and Scott was thorough in his explanations and transparent about costs. When the time came to begin the project, the team that showed up was friendly, professional and timely in getting the project done. The cleanup afterward was such that it looked like they hadn't been there at all. The roof looks great, there were no surprises and Scott came by to inspect the work and explain the warranty upon job completion. I would highly recommend them.

My neighbor had their roof replaced and I was really impressed with the speed, carefulness and quality of the work I saw. Asked her for her experience and she told me she would highly recommend J & B. I called Scott to set an appointment. He showed up on time and was very thorough in his assessment, also letting me know about some other issues and advise on where to get help. J & B is a fantastic company to deal with - their people are incredibly careful about the work they do, clean up and leave the property in the same condition as when they started, were careful about plants and the house, and work very efficiently. The office staff is great about following up, checking in and very responsive to anything that comes up. I was happy with the price charged. If you are looking to replace your roof, you should be calling J & B to get the job done.

We had work done by the J&B team at a commercial property and were very pleased with the whole process. Their estimator met us onsite and communicated with us every step of the way. They went over the scope in detail and the work performed exceeded what we were expecting. They found some additional concerns during the installation that were quickly addressed and communicated to us and to our surprise, there was not an additional charge. Our tenants reached out to share how respectful the employees were during the installation and how clean everything was left afterwards. As the project was wrapped up, we were walked through the completion paperwork and provided the warranty information. Very impressed with the professionalism of this company and would not hesitate to refer their services or use them again in the future.
