The cost of roof repairs increases by an average of $2,000 each year, and according to the National Insurance Crime Bureau, the cost of repairs due to hail and convective storms alone doubled between 2021 and 2022. Higher repair costs, rising insurance deductibles, increased material expenses, and inflation have all contributed to the growing cost of roof replacements.
These costs highlight the need for homeowners to understand and recognize different types of roof damage to get the full value of their insurance claims and hire the right contractor for their roof replacement job. Often, it is better to replace your roof before the damage becomes increasingly more expensive to repair.
Consider these 10 warning signs that indicate you need a roof replacement to avoid more costly repairs in the future.
1. Cracked or Curled Shingles
Shingles begin cracking or curling when damaged by weather or normal wear and tear. Harsh sunlight can weaken shingles while harsh wind and rain can lift or displace them. Visible changes in the alignment or shape of the shingles can allow water in and cause moisture damage or prompt mold growth.
2. Bald Spots
Asphalt shingles are covered in asphalt granules, which look like small stones embedded in the material. These granules make shingles last longer by providing partial protection from harsh wind, hail, heat, and rain. Over time, the granules can fall off, creating “bald spots” that allow moisture to access the underlayment and UV rays to penetrate the roof diminishing efficiency.
3. Warranty Ending
Roof warranties are often a good indicator of your roof’s projected durability as they are based around the life expectancy of the roof. Consider a roof replacement before your warranty ends, since labor or material costs may still be covered.
4. Blisters on Roof Membranes

Roofs are layered with different materials, including a waterproof layer called a membrane and a substrate layer, commonly made of wood. When moisture or air gets trapped between these layers, they can blister.
When the sun heats these blisters, they gradually expand, separating the membrane from the substrate. These blisters compromise the integrity of the material and are susceptible to puncture which can lead to leaks.
5. Cracks or Stains in the Ceiling
Cracks or stains in the ceiling often indicate hidden water damage. As moisture enters and gets trapped, it can expand, damaging the surrounding material. For homeowners who don’t have direct access to a view of their roof, this cracking could be the first visible sign that the roof needs to be replaced.
6. Sagging Structure
This is a critical sign. Visible sagging could indicate your roof is allowing water in, bloating absorbent materials, and causing the structure to sink under the pressure. If you notice sagging, you should have the roof inspected before the damage worsens or results in a structural collapse.
7. Mold Growth
Mold growth is another tell-tale sign that your roof no longer offers full protection from moisture. If water gets in, mold, mildew, and wood rot can damage the underlying roof structure and become a health hazard. This should be remedied immediately.
8. Flashing Damage

Flashing is a system typically using metal or rubber material to guide water away from critical structures on the roof, such as chimneys and vents. These are designed to last for many years, but they can become damaged by the elements over time.
Visible damage to roof flashing can indicate that water is not being properly redirected. In that event, other areas of the roof have likely also sustained damage due to wind and rain.
9. Rising Energy Costs
Energy costs in Maryland are rising due to planned utility hikes, inflation, and rising infrastructure costs. However, your energy bill may be rising faster than normal due to lower energy efficiency caused by damage to your roof. As materials wear out, they allow more heat and air to enter and escape, forcing the home’s internal temperature controls to work harder to maintain the preset temperature.
10. Leaking Lights
When roofing materials let too much water in, it can be channeled to low points like light fixtures and leak through the seams. Light fixtures in the ceiling can begin leaking if water has accumulated under the roof. However, this can also be due to plumbing issues, so it’s important to schedule an inspection if you see water dripping from your ceiling or lights.
