Flashing Replacement in Onsted, MI

Most roof leaks in Onsted don't start in the middle of the roof — they start at the flashing around chimneys, valleys, and roof transitions. G.I. Bros Construction replaces worn or failed flashing across Lenawee County with properly sealed, watertight detailing that stops leaks at their source before they rot your decking or stain your ceilings.

Flashing is one of the most critical components of your roofing system, sealing the vulnerable areas where the roof meets walls, chimneys, vents, and skylights. Damaged or improperly installed flashing is the leading cause of roof leaks. G.I. Bros Construction provides expert flashing replacement using premium materials and techniques that ensure lasting protection. Our team inspects and replaces step flashing, counter flashing, valley flashing, and drip edge to create a comprehensive moisture barrier for your home.

Built for Onsted’s Conditions

Onsted's Irish Hills location brings wind exposure across open lakes and higher elevations, plus lake-effect moisture that accelerates wear on shingles and flashing. Lakefront cottages and year-round homes alike need roofs that handle ice, wind, and moisture, so we emphasize ventilation and premium underlayment.

Onsted Permits & Building Codes
