A homeowner in Westford contacted us after ice buildup around a vent pipe penetration compromised the existing flashing and created an active leak risk during a Massachusetts winter. We carefully removed ice buildup around the pipe using non-damaging methods, lifted surrounding shingles to fully expose the penetration zone, and installed Grace Vycor Ice and Water Shield as a watertight secondary barrier beneath a new lifetime pipe flashing — properly integrated with the existing roof system. Replacement shingles were installed and sealed per manufacturer standards to restore full weatherproofing at the repair area. If you're in Westford or nearby towns north of Boston dealing with a pipe flashing leak or ice buildup at a roof penetration, schedule your free inspection today.
