Most full asphalt roof replacements on a Sewickley home run $14,000 to $30,000, while natural slate replacement typically runs $1,800 to $3,500 per square. The spread is wide because the housing stock here is steep and cut-up. Pitch, valley count, dormers, decking condition and material choice move the number far more than square footage does.

Assume yes, and let us handle it. Municipalities in the Sewickley Valley generally require a permit for roof replacement, and requirements differ between Sewickley Borough, Edgeworth, Glen Osborne and the townships. We confirm the current requirements with your municipality before work starts and pull what's needed as part of the job.

It can, so verify before you buy materials. Properties in and around the Sewickley Historic District may face review of visible exterior changes, including roofing material and color. We confirm the current process with the borough for your specific address rather than guessing, and we plan the material selection around whatever review applies.

Architectural asphalt typically gives 18 to 25 years here, noticeably less than its rated life. The valley's freeze-thaw cycling, deep shade and heavy tree debris are hard on roofs. Natural slate lasts 75 to 150 years, but the copper flashing under it usually needs rebuilding at least once in that span.

Usually, yes. If the structure is sound and the slate isn't broadly delaminating, a slate roof can be restored for a fraction of replacement cost. Most slate leaks we open up in Sewickley and Edgeworth are failed copper flashing and valleys, not failed stone. Get a real slate assessment before anyone quotes you a tear-off.

Targeted slate repair generally runs $900 to $4,500 per visit, and a soldered copper valley or flashing rebuild with slate reset around it runs $4,000 to $12,000. That is dramatically less than replacement, which is why we assess before we quote. Small work now prevents deck rot that turns into a structural project.

Sometimes — it's the right call when the framing can't carry natural slate, when the original is unmatched or already gone, or when the budget is real. It's the wrong call when your slate is sound and repairable, or when a historic review expects the original material. Weight, warranty and visibility from the street decide it.

Because flashings are where freeze-thaw does the most damage. Water sits in the seam between two materials, freezes, expands, and widens the gap a little each cycle. Chimneys, sidewalls, valleys and skylight curbs fail long before the field does — which is why a leak here almost never means you need a whole new roof.

Heat escaping into the attic melts snow that refreezes at a cold eave, and shaded north slopes in the valley never get sun to clear it. The permanent fix is air-sealing the ceiling plane and restoring soffit intake and ridge exhaust so the deck stays cold, plus ice-and-water membrane at the eaves. Heat cable only manages the symptom.

Hand removal plus a low-pressure biocide treatment, never a pressure washer. Pressure strips slate's surface, breaks the stone at its edges and drives water up under the courses. Moss holds moisture against slate and accelerates delamination, so it's worth removing — carefully, and usually with trimming back the limbs that keep the slope wet.

One to two days for a straightforward asphalt tear-off, three to five for a large or steep Sewickley home with multiple porch roofs and dormers. Slate and copper work is measured in weeks, not days, because it's hand work. Weather and hidden decking damage are the two things that extend a schedule.

Yes. We document the damage with photographs, meet your adjuster on the roof, and walk the same slopes so nothing gets missed. The part that matters most on older Sewickley homes is making sure slate, tile and copper are valued as what they are instead of being scoped as an asphalt repair.

Not at this time. We quote in writing with a clear scope so you can compare honestly, and we're straightforward about what has to be done now versus what can wait a season. If a repair can buy you a year or two before replacement, we'll tell you that instead of selling you the bigger job.

We carry insurance and our Pennsylvania Home Improvement Contractor registration is in process — we'll post the number here the moment it's issued. We won't claim a certification or license number we don't hold yet. Ask us directly and we'll show you exactly what coverage is in place before we set foot on your roof.
