Insulation Services in Onalaska

From attic insulation to targeted upgrades, First American Roofing & Siding, Inc. improves how your home retains heat and controls airflow. Our team focuses on sealing gaps and installing the right materials to deliver consistent comfort and long-term efficiency.

Attic Insulation

Seal and insulate your attic to reduce heat loss, eliminate drafts, and improve overall home efficiency.

Blown-In Insulation

Blown-in insulation fills gaps and hard-to-reach areas quickly, helping improve coverage and energy performance.

Crawlspace Encapsulation

Crawlspace encapsulation is an important part of whole-home energy efficiency.

Spray Foam Insulation

Expanding spray foam insulation seals gaps, blocks drafts, and boosts your home's energy efficiency in attics and walls.

Insulation Access You Can Only Get During a Re-Roof

Because we are both a roofing and insulation contractor, we can access and insulate areas that are impossible to reach any other way. When your roof is open during a re-roof, we can add or upgrade insulation in vaulted ceilings, flat roof assemblies, low-slope porch roofs, and three- and four-season rooms—spaces that are typically inaccessible without tearing out interior finishes.

This is a unique opportunity most insulation-only companies simply cannot offer, and it can make a significant difference in comfort and energy performance in those hard-to-treat areas of your home.

Stellar Roofing Company

October 01, 2026

"First American recently completed a full roof replacement with gutters on my house and did a superior job. Before beginning the job, I was given a clear, written estimate for the work that needed to be done. The crew arrived on time and finished the work in an extremely timely manner. Clean up was thorough, including use of a magnetic device used to pick up stray nails if there were any. I would especially like to thank First American's Bob Bratcher for his attention to details throughout the project, and for going above and beyond with his help in cleaning up. I am giving First American 5 stars for this job very well done! I would definitely recommend First American Roofing and Siding for anyone looking for a stellar roofing company."

Nick N. came out right away, even though it was still raining, found the issue, and had someone there almost immediately to get it fixed. Great service, very responsive, and easy to work with. Highly recommend!"

New Roof Installed

July 02, 2026

"Thanks so much for all your good work. I appreciate Jim H. for explaining everything and getting the ball rolling. Thank you Adam for getting the leak fixed before winter! Nate was excellent at coordinating the work and keeping me informed. Wyatt was so good about finishing the final work - quietly and efficiently. I was not here when the new garage roof was installed so I didn't get to thank those workers, but it looks great! Five Stars!"

Easy to Work With!

"First American just finished re-siding my entire house and replaced the gutters and downspouts due to the hailstorm from last year. Erik, the foreman, was very easy to work with and was extremely responsive and helpful with any questions I had throughout the process. I am very happy with the work they did, and I highly recommend them to anyone."
