Your roof can suffer damage from storms, debris, age, and other hazards. Many minor types of damage can be repaired by a reputable roofing contractor who restores your roof to its former condition.

However, no roof lasts forever. If the damage to your roof becomes extensive or major, it may be more cost-effective and efficient to simply re-roof.

In this blog, we list nine warning signs that it's time to consider roof replacement rather than repairs.

1. Advanced Age
Even the highest quality roofs do not last as long as the average home.Shingled roofs can last anywhere from 15 to 25 years, depending on the

climate and the quality of the materials.
If you know that your roof is over 20 years old, you should schedule an inspection at least once a year. If you notice any of the other symptoms on this list and your roof is getting old, the roof probably can't be salvaged.

2. Buckling

Weathering can sometimes change the shape of your roofing materials. Buckling occurs when wind or moisture intrusion causes the shingles not to line up.

Buckling is usually most evident on long vertical stretches of roof. If the line of your shingles looks wavy instead of straight, the shingles have begun to warp and may need to be replaced in whole or part.

3. Damaged Flashing

Not all serious roof damage stays isolated to the shingles themselves. In some cases, the damage can also affect the flashing around the chimney or vents.

If you see gaps or missing areas in your flashing, the shingles around the damage likely need to be replaced as well. Openings in the flashing make your roof vulnerable to moisture and pests.

4. Damaged Shingles

Perhaps the most obvious sign that a roof needs replacing is extensive shingle damage. Shingles generally exhibit curling, clawing, or cracking. Curling occurs when the edges of the shingles start to lift up, making them susceptible to coming off in the wind.

Clawing is the opposite of curling, when the edges of the shingles stay flat, but the middle begins to bow upward. Clawing may indicate a moisture issue.

Serious shingle cracking generally leads to portions of shingles falling off, which may contribute to loose granules, as we'll discuss in the next section.

5. Loose Granules

Sometimes as shingles deteriorate, they crumble into particles known as "granules." Granules may look like coarse sand or rubber pellets, depending on the size.

You may notice granules building up at the edges of the roof, inside your gutter troughs, or around the perimeter of your home. A large amount of granules indicates that your shingles are going bald and no longer offer your roof adequate protection.

6. Lost Shingles

All types of shingle damage can eventually lead to shingle loss. When whole shingles go missing, they leave gaps in the lay of the roof. These areas are significantly more vulnerable than the covered portions of the roof.

With shingles gone, the underlayment of the roof becomes exposed to the elements. Over time, missing shingles are highly likely to lead to roof leaks.

7. Multiple Leaks

Leaks in the ceiling can come from several different sources, from overhead pipes to overflowing gutters. Many of these leaks do not appear as rivers of water from the ceiling. Instead, you may notice stains or dark trails in the ceiling, accompanied by a musty smell.

A roofing contractor can assess the situation and identify the source of the leak. If there are multiple leaks in your roof, it will need to be replaced.

8. Sagging

Certain roof hazards can damage the sub roof and underlayment while leaving the shingles mostly untouched. For example, extensive termite damage could undermine the roof's structural integrity over time.

If you notice that portions of your roof appear to sag, have the roof evaluated as soon as possible. These sections could collapse under pressure and cause significant damage to the framing, interior, and electrical system in your home.

9. Visible Holes

In some cases, roof holes can progress quickly. Large roof holes may be start out small and become expanded due to pest infestations or weathering.

If you can access your attic space, look for any places where daylight shows through the roof. These advanced holes indicate the need for immediate re-roofing.

You may need to use a ladder in order to see many of these symptoms yourself. Remember to use best practices and common sense when accessing your roof. Always use a sturdy ladder than is firmly planted, and avoid getting onto the roof if you have any doubts about its structural integrity.

If your roof exhibits any combination of the signs listed above, consult with an expert roofer from Select Exteriors. We replace roofs of most varieties, including asphalt, tile, wooden shakes, and metal.
