Replacing Old Roofs

If your current roof is failing or reaching the end of its life, Olsen’s Roofing has you covered with our full roof replacement services. We begin by removing your existing roofing, assessing the condition of the decking, and installing a durable, weather-resistant system that matches your home’s style. Every detail—from underlayment to flashing to ridge ventilation—is installed to manufacturer specifications to ensure maximum performance and warranty coverage. We are proud to be certified installers of Drexel and CertainTeed roofing materials, though we have plenty of knowledge about and experience with many other manufacturers’ products.

What to Expect From Our Roof Installation & Replacement Processes

At Olsen’s Roofing, we prioritize clear communication and detailed planning. Our installation and replacement processes begin with a free inspection and consultation. We provide a detailed proposal with an accurate timeline and cost estimate. Once the project begins, we remove all old roofing materials, replace any damaged plywood, install your selected roofing system with underlayment and flashing, and complete the ridge vent installation. After the work is done, we clean the site thoroughly and conduct a final inspection to ensure every detail meets our high standards and your high expectations.

Very happy with the metal roofing job done here recently at my home in the chilly month of January! Communication with Barry was outstanding. The crew is a very impressive and well oiled machine. Hardworking, speedy and efficient. Kudos and a big thank you to Olsen roofing.

We just had the roof on my house replaced by Olsen Roofing and couldn't be happier! We decided to go with standing seam instead of replacing the asphalt with more shingles. Not only does it look great, it will far outlast anything we could have had done with shingles. I would definitely recommend giving them a call if you are looking for someone to replace your roof.

We had our 20+year roof completely replaced. Olsen Roofing was 100% professional from the initial in person consultation to the post job follow up. Work was done in a timely manner and workmanship was top notch. Would highly recommend.

The Olsen crew did a wonderful job, managing to do a full plywood/roof install in one day despite the fact that our barn had several (5-6!) layers of old asphalt shingles on it. They also did an exceptional job cleaning up the site, you couldn't even tell a roof replacement had been done by the time they finished. Highly recommend Olsen, and would absolutely hire them again!

These folks put a metal roof on my house in a day, including stripping the old asphalt shingles. They are super fast and super nice. Did exactly what I needed on schedule. No supply issues; no scheduling delays. And I couldn’t be happier with the result!

Olsen Roofing provided absolutely outstanding service from start to finish! The crew was amazing—professional, efficient, and incredibly thorough. They removed 8 skylights from our garage, installed new shingles, and finished everything in just one day. Even better, they left the property cleaner than when they arrived.
