Roof replacement isn't something that you should put off — damage to the roof can compromise your entire home by opening it up to water damage. The hard part for many homeowners is deciding when it is time to call in a roofer and put on a new roof. The following 5 signs can help you decide if the time has arrived for a new roof.
1. Cupping and Curling
Asphalt shingles should lay flat and overlap evenly. If the shingles begin to curl and cup at the edges and sides, or if any of the shingles are wavy and no longer laying flat, your roof has begun to degrade. Cupped and curled shingles allow moisture to seep beneath them, which means this moisture can now make its way into your attic.
2. Broken and Missing Shingles
A single broken or missing shingle may only indicate that you need a quick repair, but it's time for a replacement if you have many missing or damaged shingles. Damage includes cracks and tears in the shingles as well as broken pieces. Often, you will spot broken bits of shingles in your gutters or on the ground after a storm or a windy day.
3. Gravel Loss
Asphalt shingles are covered with a layer of gravel that helps protect the shingles and adds to their waterproofing. Some gravel loss is expected over time, but if gavel is clogging your gutters or gathering in large piles at the ends of your downspouts, then a replacement may be due. For homes without gutters, you may spot increased gravel buildup along the perimeter of your home, directly under the eaves.
4. Flashing Damage
Flashing strips are installed around chimneys, roof vents, and sometimes in roof valleys. These metal strips are sometimes caulked into place. If the flashing has holes, crumbling caulk, or is bent or warped, then you need to call a roofer. Sometimes the flashing can be repaired, while in other instances damaged flashing is just one symptom of a failing roof.
5. Moisture in the Attic
Is your attic damp or does it have a musty, mildew-like odor? Water often gets into the attic through roof leaks. If you have water spots on the attic ceiling or damp and moldy insulation, your roof may be failing. A roofer can verify that the water is coming from the roof, and not from insufficient attic ventilation.
