How to Know Whether to Repair or Replace a Roof


Replacing your entire roof can be a big investment.

But, choosing to repair just a part of it could end up being a costly mistake, especially if the repairs don’t last and you end up incurring more even damage to your roof in the long run, should the problem get worse.

If you’re wondering how to tell when you need new roof versus a repair or just a few new shingles, take a look at our tips below.

Consider the roofs age

When it comes to your roof, age isn’t “just a number,” but rather an important factor to consider when you’re deciding to replace it or not.  As a general rule, if your roof is more than twenty years old it’s time to think seriously about investing in a new one. If you’re experiencing problems with a roof that’s five years old or less, there’s a good chance you can get by with a roof repair.

Consider the roofing materials

If your roof is older and you’re seriously leaning towards choosing a new one, it’s time to think next about what material it’s made from. Asphalt single roofs last about twenty years, wood shake roofs last about thirty years, while slate, copper and tile roofs last well over fifty years.

Look for signs of damage

If your leaking roof is causing problems in other parts of the home, it may be time to replace it, especially if you’re dealing with significant water damage. Once water – from rain or even melted snow – gets underneath your shingles, it can leak into the home and wreak havoc on your ceilings, walls and even floors.

Additionally, water damage can be very bad for your health if it leads to mold growth in your home. If you see brown or green tinged water spots on your walls or ceiling, it’s probably time for a new roof.

Signs after a bad storm

If you’re experiencing issues with your roof after a bad storm, tornado, or another type of natural disaster, you might need a new roof. Did your find parts of the roof like shingles or tiles on the ground after the storm? If so, it could be a sign of extensive damage. The only way to tell is to have your roof inspected by a roofing professional.

Loose shingles

How bad can a few loose shingles be? That’s a good question. Sometimes, especially during a storm with particularly strong winds, shingles can break or get lost. If your roof is newer, you may be able to replace the shingles without needing any additional repairs. Again, your best bet is to call a roofing professional who can thoroughly inspect your roof and let you know for sure.

Is patching the roof enough

Many homeowners wonder if patching a part of the roof that’s eroded or is otherwise damaged is enough. Sometimes patching an area is possible, but usually only if it’s small. If you’ve noticed a part of your roof is sagging or caving, or if you see pebble-like pieces on the ground near your home (the substance that protects the outside of your shingles) there is a very good chance you need your roof replaced.

Check your roof repair record

One of the best ways to determine whether you need a new roof, or a repair is to look at your records and see how often you’ve invested in repairs over the years. If there have been a few, and especially if they’ve gotten more extensive over time, it may be wise to invest in a new roof.
