Full Home Insulation and Performance


Encapsulating your crawl space has a big impact on indoor air qualit and reduces the chance of moisture-related issues inside your home. You will also experience reduced energy bills and increased interior comfort.


Box sills are often the least insulated part of a home. Fiberglass batts are commonly used to save on cost, however, this can trap moisture, leading to mold growth. The best solution is to replace the fiberglass batts with 2-part closed-cell foam.


Air sealing is becoming more popular because of the insulation benefits it has, and has even become required by code in some areas. Before we insulate an attic, we make sure that it’s properly air sealed.


We use high-quality cellulose insulation for every installation. Cellulose insulation has a better r-value than fiberglass, and resists rodents and bugs.


Spray foam insulation is up to 24 times more resistant to air infiltration and creates an excellent barrier against the elements. We use spray foam where there are space constraints and a high r-value per inch is needed.


Contact us about your need for insulation. We look forward to helping you craft your house into the home you've dreamed of.

Frequently Asked Questions

What are the benefits of having a properly insulated home?

If your home was or is poorly insulated, you will notice it will stay warmer in the winter, and cooler in the summer. The goal of insulating your house is to make it run more efficiently despite outside weather conditions. Poorly insulated homes can also generate mold in the attic, and create a warm bed for mice and rodents.

Can having a well-insulated home save money in the long run?

If you have high heating bills in the winter, and ac expenses in the summer, you could reduce that expense by improving your home's insulation. How much you will save is dependent upon your home's size and the current state of its insulation. Many customers received their return-on-investment in as little as 7 years.

First American Roofing was very professional from start to finish. When my insurance company didn’t want to admit my roof had hail damage, they stepped in and did all the needed work to prove it. Thanks First American!

First American Roofing and its salesman, Anthony, were excellent. Anthony was on time for all appointments and communicated very well with me throughout the process. He stayed involved and even inspected the job for me taking pictures, as I was out of town during the install. They do top quality work that exceeds all standards. I highly recommend them.


Linda Thesing

Every member of their amazing team was so professional, personal and attentive to all the details of this whole project. Each and every person I dealt with during this process was completely amazing. I am by no means an expert on any of the things they did but I was completely comfortable with everything they did. I would have them come back for any other project they could do here but I am sure there is nothing else left to do! I love my home again!


Mark Wieser

We met with Mark to determine the type of siding we wanted and appreciated his honesty and no-pressure attitude. They offered the Everlast line, which we ended up going with for its appearance and low maintenance. Zeke and his crew did a great job- high quality work and very clean. We also got the pleasure of meeting with the owner Dallas. He was honest and fair with us and had a genuine concern that the project went well.


Rob Lenox

First American did all they said they would do. They were always available to address any concern. I would recommend 1st American roofing as trustworthy company to do business with.


Roberta Haugen

First American Roofing and Siding came out to give us a bid on the day we called them. Coltan answered all of our questions and was very professional. They were able to schedule our house washing in a timely manner. Their work was excellent. We would recommend them to you.


Jenna Sanchez

I recommend working with Paul Lentz. He is very helpful and nice. Our roof looks great. They had affordable pricing as well.


Randall Urich

Thanks to everyone at First American Roofing for a job well done! They are highly professional, fair priced, promised us high quality product and workmanship, and kept that promise. We highly recommend them.


Richard Seeks

Very professional from start to finish. You know exactly what they are doing and why. Cleanup is meticulous. I would definitely use them in the future but I’m not sure I can outlive the guarantee.



I am so relieved to have found a roofing company that was professional, friendly and thorough. Not only do I have an excellent quality roof, but it was also at the fairest price. First American really has an efficient system in place! They even have an excellent vinyl washing system that made my whole yard fence like new in no time. I will trust them again with my next home.


Damian Stanton

I have to say I was incredibly impressed with the team First American sent out to remove our ice dams. From the time the men arrived to the time they left, I saw hard work, professionalism and honesty. These are definitely qualities I look for in a company who is to be working on my home. I will definitely think about using First American again should I need any future work done!


Larry Messerly

Was very impressed. Known damage to the roof sheathing was replaced, rotted soffit replaced. Workers did a good job cleaning up and respecting property. Supervisor came the next day and only found a handful of debris they missed.


Becky Hamit

So glad we found First American for our siding needs. The crew was extremely professional and detailed. Site was always clean and picked up after each day. They encountered a couple issues on our home upon tear off and resolved them nicely before putting on new siding. Would highly recommend!


Bree Bushman-Lee

Mark came to our house and was very knowledgeable when explaining the issues for our roof and what they would offer. He offered 3 different options and took the time to explain everything to us so we understood what was going to happen. The project only took 2 days and the roofing team even worked while it was raining to make sure the roof got completed.  Everyone that I interacted with including Mark, Andrew, Scott and Ruben’s team were very professional and we will be going back for additional house projects.
