Borda Enterprises | General Contractors & Roofing in West Allis, WI 53214

A leaking valley often points to underlying wood rot or damaged sheathing, which is a carpentry issue at its core. Our team at Borda Enterprises first assesses the structural integrity of the roof deck and framing in the valley area. We then expertly remove and replace any rotted or compromised wood, ensuring a solid, level base before any new underlayment or shingles are installed. This precise carpentry work is critical for a permanent seal and prevents the leak from recurring, which is common with quick surface-level fixes.

In West Allis, damaged underlayment usually means the roof decking (sheathing) beneath has been exposed to moisture and may be compromised. Simply laying new underlayment over weak wood won't last. Our carpentry specialists meticulously inspect and replace any soft, warped, or rotted decking boards. We ensure the entire substrate is flat, secure, and properly nailed—a foundational step that guarantees the new underlayment adheres correctly and provides the durable secondary water barrier your home needs against our local weather.
