"Our roof was at least 15 year old and it had been over 5 years since our last inspection so we had Richard come out and see if any work was indicated. He came out quickly inspected our roof and said that we had no damage and reassured us that we likely had another 5 years on our roof. We greatly appreciated his honesty! Will definitely have him back."

"Our roof needed to be replaced following the May 2025 tornado in St Louis. The job in itself was not super complicated, but there were many moving parts including dealing with the insurance, handling solar panels, etc. These guys did an excellent job, and I would work with them again if I had to start all over. They were particularly good in handling the back and forth with the insurance, and the whole project was completed in a very reasonable time. Most houses in my neighborhood are still waiting for a new roof..."

"I called Coldstream after a hail storm damaged the roof of our commerical building. Part of the roof is flat but there are 3 corner towers which are two stories high and pitched shingle roof lines. First contact with Coldstream was Julie. Very professional and quick to respond. she took the information and arranged for project manager, Ricky, to inspect the damage. Ricky sent me multiple pictures showing the damage to shingled part of roof. He was also honest and up front that the flat part of the roof was not damaged. He did an excellent job picking a comparable color of shingle as the original color was discontinued. Ricky kept in communication when install crew would arrive. Crew arrived, made the install and left the ground around the building very clean and undisturbed. Even my 3 retail tenants were happy with the installation. Highly recommend Coldstream for their excellent work, professionalism, and honesty."

"Dave Dawson and team were a joy to work with when putting on my new roof. Their communication, professionalism and dedication to detail and quality were excellent. Being a single homeowner, selecting a Roofing company can be a daunting task. After doing extensive research and other bids, Dawson checked all the boxes to my great satisfaction. I also had referrals for using them by very satisfied customers. Dave, the owner, works with you personally and does a thorough final inspection to meet his stiff standards. My crew, Gary and Karl, were very hardworking, courteous and easy to communicate with during the process. They have worked for Dave since the mid eighties. I would give them an A+ in knowledge and workmanship Kathy, in the office, became my new best friend. If you want peace of mind to know you roof is on right and esthetically pleasing donâ  t hesitate to use this company. My last roofer cut corners unbeknownst to me. I trusted Dawsonâ  s honesty and showing me the prior damage. It has been a great business relationship. Iâ  ll sleep well tonight with expected heavy rains. That means everything to me. Mary Lou W"

Roofing questions, answered by experts

In O'Fallon, address roof leaks, missing or cracked shingles, and visible sagging as soon as possible, especially before winter or storm season. If you’ve recently experienced hail or wind damage, act quickly to stay within insurance claim windows. Minor issues like small stains or slight discoloration can usually wait, but always monitor for changes. Prioritize repairs before tornado and hail season for peace of mind.

Helpful?

In MO, choosing Class 4 impact-resistant shingles or metal roofing helps roofs withstand hail and wind. Proper attic ventilation and ice-and-water barriers are vital for managing humidity and storm runoff. Insist on professional installation with correct flashing and ridge venting. Regular roof inspections after major storms and keeping gutters clear also extend the lifespan of your roof and prevent costly repairs.

Helpful?

In MO, be cautious of roofers who avoid discussing local permit requirements, ventilation, or specific materials for storm protection. Watch out for vague contracts, lack of recent local references, or requests for large upfront payments. Extremely low bids may signal shortcuts or subpar materials. After storms, avoid high-pressure sales tactics or door-to-door offers. Always verify that the roofer’s materials meet local wind and energy standards.

Helpful?

In O'Fallon, look for curling or missing shingles, shingle granules collecting in gutters, or flashing that’s rusted or lifting—these can signal poor roof repair or storm damage. Water stains on ceilings, mold in the attic, or persistent leaks after rain are also red flags. If your roof looks patchy or repairs don’t match existing materials, a professional evaluation is recommended.

Helpful?

In O'Fallon, most roof replacement projects on homes are finished within 2-5 days, while roof repairs often take just 1-2 days. New roof installations for construction can require 3-7 days, depending on roof design and weather. Sudden storms or cold snaps may add delays, so scheduling outside peak storm season or planning ahead for spring and fall can help keep your project on track.
