Shiloh is a rapidly growing village in St. Clair County, Illinois, adjacent to Scott Air Force Base and conveniently located along the Interstate 64 corridor. The community is known for its modern subdivisions, newer housing stock, and family-friendly atmosphere. Most homes in Shiloh were built from the late 1990s through the 2010s, featuring contemporary designs, open floor plans, and construction that reflects modern building standards. The village’s growth has been fueled by military personnel stationed at Scott AFB and families drawn to the area’s newer schools and amenities.
Gallagher Bros Construction has been a trusted roofing contractor serving Shiloh, IL (62269) and the surrounding Metro East Illinois area since 1973. As a locally owned and operated company with over 50 years of experience, we understand the specific roofing challenges that homeowners in Shiloh face and deliver solutions built to last.
Although Shiloh’s housing stock is relatively new, homes built in the late 1990s and early 2000s are now reaching the 20- to 25-year mark, which is when many builder-grade shingles begin to show age. The flat, open terrain surrounding Shiloh provides limited wind protection, leaving roofs exposed to the full force of the severe storms that regularly move through the Metro East. Hail damage is a particularly common issue, and homeowners who have not yet replaced their original builder-grade roof may find that storm damage accelerates the need for a full replacement.
With over five decades of experience in the St. Louis region, Gallagher Bros Construction brings the expertise and local knowledge that Shiloh homeowners need. We are Licensed and insured in the State of Illinois, and our team includes industry professionals from multiple trades who ensure every project meets our high standards for quality and craftsmanship.
We believe every job should be worthy of a five-star recommendation, which is why thousands of satisfied customers across the St. Louis area have trusted us with their roofing, siding, and window needs.

We had severe hail damage to our roof and siding from the spring storms of 2025. Gallagher Bros. Construction was recommended to us as a great company to use. We truly had a great experience working with Rex and the work crews that came to replace our roof and siding. Both projects, with the roof in November and the siding in February, were completed within the span of two days. Both jobs were done extremely well! The best part about working with Gallagher is their work with the insurance companies. They worked on our behalf to help us get the maximum amount of money we needed from our insurance to pay for the work completed. Everything was handled professionally from start to finish - and we could not be happier with the work completed! We will definitely be recommending Gallagher Bros. Construction to anyone that needs their services - and we would love to work with them again if the need arises!Posted on Joe ChickTrustindex verifies that the original source of the review is Google.
