Our Verified Reviews

Your Trusted West Michigan Roofing Contractor

Portage, Michigan, is our home. We play an integral part in our community and are dedicated to serving our neighbors. As a resident and locally owned roofing contractor, we understand the concerns of property owners in the area.

Being near the lake has many adverse effects on roofing due to the harsh weather conditions. High winds, snow and ice buildup, hail, intense sun exposure, and extreme temperatures can cause severe damage to a roof if not adequately taken care of. Wind-driven rain and snow can cause water to seep into the roof, leading to rot and mold growth. Hail can cause dents in metal roofs and crack shingles that reduce the life of the roof. Intense sun exposure can break down shingles and other materials over time, exposing them to more damage from weather elements. Extreme temperatures can cause the expansion and contraction of materials, leading to cracks and gaps that allow moisture in. All of these things can add up to a lot of costly repairs or even the need to replace your roof prematurely.

It takes high-performance roofing to sustain these harsh elements. We at Magnum Roofing have the materials, automated technology, expertise, and experience to deliver the best results.

Roof work is disruptive and expensive. It can also be very intrusive and time-consuming.
