 Trustindex verifies that the original source of the review is Google. Oliver and William were very friendly and professional and their team did great work! Very happy with our roof and siding and window wraps. I would recommend them to anyone looking to fix up their house. This is the second time they've fixed up our house in 2 years (thanks hail!) And both times they've done excellent work.

 Trustindex verifies that the original source of the review is Google. We highly recommend Oliwill Construction if you are in need of a roof replacement. Oliver and his team provide reliable and fast communication throughout the process. The team ensures you have a good understanding about the work being done each step of the way. We also appreciated that the materials were brought on site the same day the work was getting done compared to our neighbors who had materials sitting on their lawn for days or weeks prior to the scheduled work date. If you’re looking for a positive roof replacement experience we recommend contacting Oliwill Construction!

 Trustindex verifies that the original source of the review is Google. Oliwill did our roof recently and it was a smooth job, start to finish. Their guys finished in a day even with a rain delay. The cleanup was thorough and by sundown everything looked just like it looked that morning. Except the roof of course, that looked 100% better. Definitely recommend Oliwill!

 Trustindex verifies that the original source of the review is Google. Since the first appointment with their team, our perception was of trust, professionalism, honesty and, they delivered. The time and scope was as it was agreed and they had helped us to navigate not only the technical-construction process, changes and currently, the closing process with the insurance. We had the opportunity to be in constant communication with Oliver but also with other team members from Oliwill and each of them, was open to solve our questions and concerns.

Roof Installation Services We Offer in Lake Mills

At Oliwill, we provide a full suite of services to meet your roofing needs:

Roof Installation for New Construction

For new homes and additions, we install complete roofing systems that meet local building requirements and are ready for Wisconsin weather from the start.

Complete Roof Replacement

When an existing roof has reached the end of its useful life, we remove the old materials, address any underlying issues, and install a new roofing system for long-term use.

Material Options for Every Need & Budget

Metal Roofing

Metal roofing is often selected by homeowners looking for longevity and minimal upkeep, especially in areas exposed to wind, hail, and heavy snow.

Asphalt Shingles

Used frequently on residential homes, this roofing type offers dependable coverage and a lower overall cost compared to many other systems.

Custom & Specialty Roofs

Steep slopes, complex rooflines, or non-standard structures require a different approach. We can offer custom and specialty roofing services to suit your needs.

Our Roof Installation Process

On-Site Evaluation: Every project begins with a visit to the property to review roof conditions, discuss concerns, and determine the scope of work.
Written Plan and Pricing: Homeowners receive a clear outline of the work, including materials, timing, and cost, before any work is scheduled.
Roof Installation: The roof is installed following local codes and manufacturer guidelines, with attention to how it will perform through seasonal weather changes.
Final Check and Cleanup: Once installation is complete, the site is cleaned and the roof is reviewed to confirm everything was finished properly.
Work You Can Rely On: We stand behind the work we do and address any concerns before considering the project complete.

When to Install a New Roof?

Replacement may be worth considering if you notice:

Shingles lifting, breaking down, or missing
Granules collecting in gutters or visible wear on shingles
Interior water stains or active leaks
Soft or deteriorating roof decking
Sagging areas or light visible from the attic
Ongoing repairs or repeated storm damage

When your roof is showing any of these signs, Oliwill Construction can provide a free inspection and estimate.
