Capabilities
Expert roof replacement services deliver long-lasting protection, stronger curb appeal, and better performance for aging or damaged roofs.

A roof replacement is often the smartest investment when repairs are becoming frequent or damage has spread across too much of the system. Age, storm impact, granule loss, curling shingles, and persistent leaks are all signs that replacement may provide better long-term value than another temporary fix. For homes in Ellisville and the surrounding St. Louis suburbs, a new roof can restore protection and improve peace of mind for many years ahead.
Every roof replacement project begins with a close look at the home’s structure, current roofing materials, ventilation needs, and drainage details. We help homeowners understand the condition of the existing roof and recommend a system that fits the property, budget, and performance goals. Whether the home needs a straightforward replacement or upgraded components to improve durability, we guide the process with clear communication and practical expertise.
A high-quality roof replacement depends on more than new shingles alone. Proper tear-off, decking evaluation, underlayment installation, flashing replacement, and ventilation integration all play a major role in how well the new roof performs. Our crew works carefully to protect the home during installation and to ensure every layer is built for lasting weather resistance.
Allen Roofing & Siding has served the Greater St. Louis area for more than 50 years, and that experience shows in how we approach replacement projects. Homeowners appreciate working with a company rooted at 525 Old State Rd in Ellisville, because it means local accountability, responsive communication, and a better understanding of regional weather patterns. We are committed to customer-first service and to delivering results that make sense for the home and the homeowner.
A roof replacement is an opportunity to improve both protection and appearance at the same time. With the right materials and installation, your home can be better prepared for heavy rain, summer heat, wind, and winter freeze-thaw cycles. If your current roof is reaching the end of its service life, Allen Roofing & Siding can help you move forward with confidence and a roof built to last.
