Residential Roof Replacement for Sun Prairie Homeowners

Sun Prairie has grown fast, and the mix of older homes and newer builds shows up in the way roofs wear. Some hold up well for years, others start showing issues earlier depending on how they were put together and what they’ve been through. Between winter buildup, spring moisture, and summer storms, it adds up. At Oliwill Construction, we step in to figure out what’s actually going on. We inspect the roof, identify problem areas, and determine whether it makes sense to repair sections or move forward with a full replacement.

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.

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!

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!

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 Sun Prairie

Roofing for New Builds and Additions

Roofing on new construction or additions has to be done in the right order, with everything in place before the rest of the exterior is closed in. We install the full system from the base up, making sure airflow, layering, and material placement are handled correctly from the start.

Full Roof Replacement

There’s a point where continuing to patch a roof just leads to more problems. We strip everything down, take a close look at the decking and problem areas, make necessary repairs, and install a new roof that’s made to handle the conditions homes in Sun Prairie deal with each year.

Material Options for Every Need & Budget

Metal Roofing: A durable option that sheds snow well and stands up to wind and impact over time.

Asphalt Shingles: A highly practical choice for most homes, offering solid protection and numerous different styles at a more manageable cost.

Custom & Specialty Roofing: Some roofs don’t follow standard lines. In those cases, we adjust the approach to match the layout instead of forcing a typical setup.

Our Roof Replacement Process

1

Initial Walkthrough: The roof is reviewed up close to understand where it’s wearing down, how previous work has held up, and what condition the underlying structure is in.

2

Written Plan: A full outline of the project is put together covering scope, materials, timing, and cost so everything is defined before work begins.

3

Installation: The existing roof is removed, the decking is checked and repaired where needed, and the new roofing system is installed in stages so each layer is set correctly and tied into the next.

4

Final Check & Cleanup: Once installation is complete, the roof is gone over again and the property is cleared of leftover materials and debris.

5

Closeout: The project is finished only after the work lines up with your plan and everything has been completed as expected.

Is It Time for a Roof Replacement?

Roof issues tend to build gradually. Signs to look out for include:

  • Shingles that are loose, cracked, or missing
  • Granules collecting in gutters or near downspouts
  • Interior staining or signs of moisture
  • Weakened sections below the shingles
  • Rooflines that appear uneven or sagged
  • Recurring repairs tied to storm impact or changing seasons 

As these issues show up, having it looked at would be advisable. We offer free estimates to help you understand what comes next.
