How to Know When Your Porch Needs a New Roof

When it is time to replace the roof on your porch, it’s often not as obvious as a drip coming through the middle of the roof.

Because of the nature of porches, the roofs on porches will sometimes need to be replaced before the roof on the house. Especially if the porch roof is not a seamless part of the roof on the house – whether the porch was built separately or the roof of the porch does not connect directly to the roof on the house.

Obviously, if your porch roof is connected seamlessly to the roof of your house, and you’ve got issues with the roof of the porch, then that’s an indication that the entire roof needs to be replaced.

But in those instances when the porch roof is separate, here are some things that you need to look for.

How Old is The Roof?

When it comes to roofs, age is sometimes the biggest indicator of whether or not it’s time to replace the roof. The roof on your porch may be older than the roof on the house.


A typical shingled roof will last between 20 and 25 years, but if the roof on your porch is not ventilated properly or has other issues, it might not last as long as the typical roof. But if the roof on your porch is more than 20 years old, there is a good chance that you will soon have to replace it.

Is There Rot?

If the columns on your porch or the fascia board are showing signs of rot, that could be an indication that your roof needs to be replaced. Rot will spread through boards, and even if your porch roof isn’t showing any other signs, rot is a strong indicator that it’s time to replace the roof on your porch.


Leaks or Water Stains

If your porch is leaking or you have water stains on the ceiling of the porch, those are also obvious indicators that the roof of your porch needs to be replaced. You can check for damaged or loose shingles or bad flashing, and in some cases a repair will solve the problem. But if the water is leaking through the ceiling or staining the ceiling, you could have serious problems that you can’t even see.


Dips in The Roof Line

If you look at the roof line of your porch and it appears to be warped with dips, that is another indicator that it’s time to get the roof replaced. That sagging in your roofline could mean that your sheathing is saturated and beginning to rot.
