Signs that a roof needs repair or replacement

Many homeowners believe a roof is a oncein-a-lifetime investment, but roof damage can force homeowners to replace a roof, regardless of how much time has lapsed since the roof was installed.

The average life span of a roof depends on when the roof was installed and the materials from which it is made. According to Central Homes Roofing, three-tab shingles may last for 10 to 15 years, architectural shingles can endure for 15 to 20 years, and tile may last between 35 and 50 years. RPS Metal Roofing indicates that a metal roof may last as long as 70 years. However, climate and the color of the roof will also affect its longevity.

Homeowners would be wise to consider these factors when determining if a roof is in need of repairs or replacement.

• Roof age: The age of the roof is a major factor in determining if it will need to be replaced or if repairs can be made to isolated damage. Individuals who live in neighborhoods where neighbors are now replacing roofs will likely find it is time to consult a roofing company. Homeowners can also check to see if they have any receipts that indicate the roof’s installation date so they have an idea about the roof’s age.

• Grain in gutters: Roofing shingles are designed to overlap, and sealant keeps them steady. Friction, weather and atmospheric changes can impact the sealant and cause degradation. Gutters with grainy material in them could indicate worn-out sealant and shingles.

• Ridge damage: Ridges are spots where two separate areas meet and are often important to the structural integrity of the roof. If the roof ridge is showing signs of wear, it could be time to repair or replace it.

• Curled shingle edges: If shingle tabs are curled or cupped, the shingles may need to be replaced. But if curling is extensive, a whole new roof may need to be installed.

• Bald spots or lost portions of the roof: Missing granules and missing shingles are reasons to consult a pro for a roof evaluation.

• Leaks indoors: Homeowners who find dark streaks or moisture in the attic may discover that water is penetrating the roof underlay. Water often comes in around chimney flashing. Other signs of water damage are blistering and bubbling in walls.

• Incoming light: Look up through the attic, and see if any light is coming through the roof, which may indicate there are cracks or holes in the roof.

• Aesthetics: If a homeowner does not like the look of the roof from a design standpoint, a replacement also may be warranted.

Roofs can last many years, but the presence of certain signs indicates that replacement or repairs will be necessary.
