Reroofing Services in Washington County, PA

Reroofing means putting a new layer of shingles on a roof. Depending on the roof, that can be done over the existing shingles or after a full tear-off. Which one is right depends on what is already up there, and that is what the inspection is for.

Rail Roofing Group reroofs homes and businesses across Washington County. We tell you plainly which option your roof can take and why.

When a new layer over the old roof can work

• The roof has only one existing layer of shingles
• The deck is solid, with no soft spots or rot
• The existing shingles lie flat enough for the new ones to sit properly
• There are no active leaks that have reached the deck or the attic

When a full tear-off is the better choice

If the roof already has two layers, building codes and good practice usually call for a tear-off. The same is true when the deck is damaged, when leaks have been going on long enough to soak the wood, or when the old shingles are badly curled. A new layer over those problems hides them instead of fixing them, and adds weight to the structure.

A tear-off also lets the crew see and replace damaged decking and install new underlayment and flashing, which a layover does not.

What to ask about any reroofing estimate

Whoever you hire, ask how many layers are on the roof now, whether the deck was checked from the attic, and what happens to the flashing. A layover that reuses tired flashing around a chimney can leak in the same place the old roof did. Our estimate answers those questions in writing.

Reroofing: common questions

What is the difference between reroofing and a roof replacement?

Reroofing can mean a new layer over the existing shingles. A replacement removes everything down to the deck first. On our estimates we say which one we recommend for your roof and why.

Can you put new shingles over my old ones?

Only if the roof has a single layer, the deck is sound and there is no water damage underneath. We check all three during the inspection before recommending it.

How many layers of shingles can a roof have?

Codes limit how many layers a roof can carry, and once a roof reaches that limit it needs a tear-off. We count the existing layers during the inspection.

Is reroofing a good option for a roof with leaks?

Usually not, if the leaks have reached the deck. Covering wet or damaged wood traps the problem. A tear-off lets the damage be repaired first.

How do I find out which option fits my roof?
