Shorter than most people assume, and the clock starts on the day of the storm rather than the day the ceiling stained.
Your policy sets the deadline, not Pennsylvania law. Almost every homeowner policy requires prompt notice of a loss, and Pennsylvania lets carriers cut the window for bringing a lawsuit to one year from the date of loss. Most of them do, and the courts here generally enforce it.
Two different clocks
The first clock is notice. Policies ask for immediate or prompt written notice of a loss. There is no fixed number of days attached to those words, which cuts both ways. A delay you can explain is usually survivable. A delay you cannot is a reason to deny.
The second clock is harder. Pennsylvania permits a policy to shorten the time for suing the carrier to one year from the date of loss, and a clearly written one year provision is generally enforceable here. That is a year from the storm, not a year from the denial letter, which is the detail that catches people out.
So the ordinary four year window for a contract dispute does not apply once your policy says otherwise. By the time a slow claim has been argued back and forth for ten months, the right to take it further can be close to gone.

What shortens your odds
Straight answers
There is no single statewide filing deadline for a property claim. It is set by the policy you hold.
Read the loss conditions in your policy for the notice requirement, then look for a suit limitation clause. If it says one year, take that as the outside edge of everything.
Often not, and it is worth finding out rather than assuming.
Hail damage regularly goes unnoticed for a season because it does not leak straight away. Get the date of the storm, get the roof documented, and file. The worst outcome is a no.
From the date of loss, which is the storm.
This is the single most expensive misunderstanding in roof claims. Noticing a stain in February does not restart a clock that began in August.
Not on its own, and assuming it does is how the window closes.
If a claim is dragging and the anniversary of the storm is approaching, that is the point to get advice from somebody who is not the carrier.
General information, not legal advice. Policy wording and the facts of a loss decide these questions, and both vary. If a deadline is close or a claim has been denied, that is a conversation for a lawyer rather than a roofer.
