Project Case Study: Tracking Down an Ice-Damage Leak on a 4-Level Townhouse

Michael Matthews had a leak on his 4-level townhouse on Oval Park Lane in Charlottesville, and he had a good theory about what caused it: snow and ice had accumulated on the roof through the winter, and once the melt started, water found its way through the shingles and into the home below. He found Cenvar through Google, our lead center booked the call, and our Charlottesville team was on site shortly after.

Why Ice and Snow Get Under Shingles

Asphalt shingles are designed to shed water that flows downhill across them. They're not designed to handle water that wants to move uphill — which is exactly what happens during freeze-thaw cycles. Here's the mechanism:

1. Snow accumulates on a cold roof
2. Heat loss from the home melts the snow at the roof-deck level
3. Meltwater runs down under the snow
4. It refreezes at the colder eaves, forming an ice dam
5. More meltwater hits that dam and backs up under the shingles
6. Eventually it finds a nail hole, a seam, or a weak spot — and leaks inside

On a 4-level townhouse where the roof slope ends at a deck-level eave, this pattern is especially common because the building's height drives bigger temperature differentials across the roof surface. If you're dealing with the same situation, our guide on dealing with snow and ice on your roof is worth reading before next winter.

The Repair-vs-Replacement Decision

When our estimator scoped the damage during the roof inspection, we gave Michael two clear options:

Option A — Targeted repair. Remove the shingles over the leaking 5'x5' section, inspect and replace OSB decking if needed, install new ice and water shield underlayment, and install new Tamko Titan XT Architectural shingles color-matched as closely as possible to the existing roof.

Option B — Full back-facet replacement. Replace the entire back facet of the roof with ice and water shield running the full surface, plus new ridge vent, hip and ridge cap, drip edge, and step flashing.

The back-facet option was the insurance-against-future-leaks choice. The targeted repair was the surgical-strike, lower-cost choice that addressed only the specific failure point. Michael chose the targeted repair.

We're transparent about one thing that a lot of roofers bury: we don't guarantee leak-fix attempts. We identify the most likely cause, explain what a targeted repair can and can't do, and let the homeowner make the call. When a repair works, great. When it doesn't, we've at least eliminated one possibility and can plan the next step without guessing. That conversation happens up front, in writing, before any work begins.

The Cenvar Solution: A 5'x5' Surgical Repair on the Back Facet

Our Charlottesville crew accessed the back roof from the 4th-level deck — the townhouse geometry made that the cleanest approach — and completed the roof repair in a single day. Here's what went into the repair section:

• Shingles: Tamko Titan XT Architectural, color-matched as closely as possible to the existing roof
• Underlayment: New Cenguard Ice & Water as a self-sealing barrier in the vulnerable area
• Penetration: New select-a-size plumbing boot with repair ring, replacing the failing boot
• Decking: OSB inspected and replaced only where needed, at a pre-disclosed per-sheet rate
• Cleanup: Full nail sweep and debris removal

A note on color matching: on any repair job, the new shingles won't match the old ones perfectly. The old shingles have years of UV exposure and weathering; the new shingles are factory-fresh. We match as closely as the available product allows and explain up front that there will likely be a visible color difference. Homeowners who need a uniform appearance usually go with full replacement. Homeowners who want to stop the leak for the lowest reasonable spend usually go with the targeted repair. Both are valid calls — we just want the homeowner making it with full information.

Common Questions from Charlottesville Homeowners

What if the repair doesn't hold?
Our repairs are backed by workmanship on the specific section we touched, but we're honest up front: we don't guarantee that a targeted repair stops every leak permanently. Sometimes a repair eliminates the primary failure point and a separate issue surfaces later. If that happens, we come back, diagnose what's next, and plan from there. The only way to fully guarantee a roof against future leaks is a full replacement with a new ice and water barrier across all vulnerable areas.

Will the final price match what's quoted?
Yes — the quote is what you pay, unless hidden decking damage is uncovered once shingles come off. Our repair proposals spell this out explicitly: OSB decking replacement at a set per-sheet rate if needed. We show you the damage before billing for any additional decking, and you approve the change before we proceed.

Do Cenvar employees do the work, or do you use subcontractors?
Our estimators are full Cenvar employees. On the install side — including repair jobs — we use vetted contractor crews, with a Cenvar project coordinator overseeing the work. For a repair, that means a Cenvar team member confirms the scope, verifies the shingle match, and signs off at the finish. No subcontractor running off without accountability.

Dealing with a Leak After This Past Winter?

If you caught water inside the home last winter and suspect snow or ice was the trigger, don't wait for next winter to diagnose it. Warm-weather inspections are faster and more thorough because we can actually access the roof without snow in the way. Schedule a free roof inspection with our Charlottesville team and we'll figure out whether you're looking at a repair or a replacement — and give you honest numbers for both.
