Roof Waterproofing

Advanced roof waterproofing in Rochester—membranes, flashings, and details that stop leaks.

Roof Waterproofing in Rochester, NY

Great roofing is great waterproofing. We harden the system where water tries to win—eaves, valleys, sidewalls, penetrations, and low-slope transitions—so your roof stays dry through Rochester’s toughest seasons. Our approach blends materials and method: self-adhered ice-and-water membranes at critical zones; synthetic underlayments that resist wrinkling; metal flashings bent to fit your details; and sealants that remain flexible in freeze–thaw cycles. Whether we’re building new or retrofitting an existing roof, the goal is the same: continuous, shingle-to-flashing-to-underlayment pathways that shed water predictably.

Critical Zones We Reinforce

Eaves & Rakes: Wider ice barrier where long eaves or cold gutters threaten dams. Valleys: Open metal or properly executed closed-cuts that resist scouring. Sidewalls & Chimneys: Step + counter-flashing with true reglet cuts and capillary breaks. Penetrations: UV-stable boots, lapped underlayment, and cover strips. Low Slope Areas: Compatible membranes and transition flashings to prevent ponding creep under shingles.

Why It Matters in Rochester

Our weather throws water, ice, and wind at every weak point. Waterproofing makes those points strong, turning your roof from a pretty surface into a robust system that shrugs off storms.

Upgrading Existing Roofs Without Full Replacement

Not every leak means you need a new roof. If the field shingles still have life, we can surgically improve weak areas. That might mean adding or widening ice barrier at eaves and valleys, rebuilding failing chimney flashings with new step/counter assemblies, replacing degraded pipe boots, or correcting low-slope transitions with compatible membranes. We’ll lift specific courses, integrate materials as if the roof were new, and restore proper laps and capillary breaks. It’s meticulous work, but for many Rochester homes it’s the fastest path to a dry interior without the cost and disruption of a full tear-off. We’ll document before/after so you see exactly what changed and why it works.

Flashing: The Unsung Waterproofing Hero

Most roofs don’t fail in the middle—they fail at the edges and junctions. That’s flashing’s job, and it’s where craft shows. We custom-bend metals to match your roof geometry, maintain proper overlaps, and create capillary breaks so wind-driven rain can’t sneak backward. At chimneys, we cut reglets into the mortar for counter-flashing that actually sheds water; at sidewalls, we step each course into the shingle field; and around skylights and vents we use manufacturer kits or proven field-fabricated details. Good flashing is why a roof keeps working long after the shingles age. We treat it like the critical component it is.

When Coatings Make Sense (and When They Don’t)

On flat or low-slope roofs with sound membranes, elastomeric coatings can add 5–10 years of service life while reflecting heat in summer. But coatings aren’t a cure-all. We’ll test adhesion, repair the base membrane first, and only coat where slope and detailing support success. On steep-slope shingle roofs, we prioritize detail rebuilding over coatings because that’s where water actually wins. You’ll get an honest recommendation either way—our goal is a dry, efficient home in every season.
