SMS Exteriors LLC | General Contractors & Roofing in Holland, MI 49423

In Holland, roof valley leaks are often caused by heavy snow, ice dams, and wind-driven rain stressing the intersection where two roof slopes meet. Debris accumulation can also wear down the valley lining. SMS Exteriors fixes these by first conducting a thorough inspection to locate the breach. We then repair or replace the valley flashing with durable, corrosion-resistant materials, ensuring a watertight seal and proper integration with your existing roofing system to prevent future leaks.

The moisture-laden air and temperature fluctuations near Lake Michigan accelerate the corrosion of traditional metal flashing, especially around chimneys, vents, and roof edges. At SMS Exteriors, we combat this by using premium, corrosion-resistant flashing materials like aluminum or coated steel. Our meticulous installation process ensures all flashings are properly overlapped and sealed, creating a robust barrier that stands up to Holland's specific climate and protects your home's most vulnerable points.

Yes, absolutely. As a full-service general contractor, SMS Exteriors can manage the entire project from start to finish. After we repair the roof leak at its source—be it in the valley or flashing—we can also coordinate the necessary interior repairs. This includes addressing water-damaged drywall, insulation, and ceilings, ensuring your Holland home is completely restored inside and out, saving you the hassle of managing multiple tradespeople.
