About Harlan & Sons Roofing

Roofing Lancaster, PA Trusts

Slate is one of the most durable roofing materials available, with genuine slate roofs regularly lasting 75 to 150 years when properly installed and maintained. In Lancaster, PA, where winters bring ice and freeze-thaw cycles and summers deliver heavy rain, high-quality slate holds up exceptionally well — it's naturally resistant to moisture, fire, and temperature swings. The trade-off is cost: slate sits at the premium end of roofing materials, typically running significantly more per square than asphalt, but many Lancaster homeowners find the long-term math compelling when they factor in the near-zero replacement cost over a lifetime of ownership.

Common questions

Frequently Asked Questions

How long does a slate roof actually last?
Natural slate installed correctly typically lasts 75 to 150 years, depending on the slate grade (soft vs. hard slate) and how well it's maintained. Some Lancaster-area homes still have original slate roofs that are well over a century old.
What does slate roofing cost compared to asphalt?
Slate costs significantly more upfront — often three to five times the price of architectural asphalt shingles per square installed. However, because a quality slate roof can outlast two or three asphalt roofs, many homeowners find it cost-effective over the long run.
Is slate a good choice for Lancaster, PA's climate?
Yes. Slate is naturally dense and non-porous, making it highly resistant to the freeze-thaw cycles, heavy snow loads, and summer thunderstorms common in Lancaster County. It won't warp, rot, or absorb moisture the way some other materials can.
Can individual slates be repaired without replacing the whole roof?
Absolutely. One of slate's biggest advantages is repairability — a cracked or slipped slate can often be replaced individually without disturbing the surrounding roof. Catching and fixing small problems early is the key to maximizing a slate roof's lifespan.
How do I know if my existing slate roof needs repair or full replacement?
That depends on the age of the slate, how many slates are damaged, and the condition of the flashings and underlayment. A free inspection from Harlan & Sons will give you a clear, honest picture — we'll tell you exactly what we see, including if the roof has many more years of life left and only needs minor work.
Does Harlan & Sons offer warranties on slate roofing work?
Yes. We stand behind our workmanship with a warranty on our labor, and natural slate itself comes with the backing of being a proven, centuries-old material. We'll walk you through what's covered before any work starts so there are no surprises.
