7 Signs Your Roof Needs To Be Replaced
Repair or Replace
Regular maintenance and repairs extend the life of your roof for a decade or longer, but when is the damage extensive enough to warrant a full roof replacement? Here are seven signs that it is time for you to invest in roof leak repair or replacement services from ReNew Roofing in Spooner.
Asphalt roofing is the most common type in the United States because it is inexpensive but durable. The roof will last between 15 and 25 years. Other roofing options such as metal, tile, or slate can last decades longer than an asphalt roof, and they often require less maintenance. These types of quality materials are expensive to install on your roof, but they may last a lifetime. Age is a significant factor in replacement versus repair for an asphalt roof because the materials degrade over time from sun exposure. Insurance companies may also deny home coverage without a roof inspection after 20 years. If your asphalt roof is 25-years-old or older, it may be time to look for a roof replacement service team in Spooner.
If your shingles are curling it is not a good thing. It is another sign it might be time for a new roof. Curling shingles occur for many different reasons including old age, installing new shingles over old shingles, improper installation or inadequate ventilation. There are also different types of curling. As roofs absorb moisture, over time, the shingles can curl inward or outward. Advanced deterioration is called “Alligatoring” and “fishmouth.”
A sagging roof is a severe problem, and it is a warning that your home is at risk of a roof collapse. Long-term water damage causes roof sagging. Moisture finds weak spots in the materials, and as it settles, it causes materials to deteriorate. The water can also encourage mold and mildew growth that will further damage the shingles and roof support. Poor ventilation can also lead to a sagging roof by causing ice dams or rusting on nails holding materials together in the attic. The Federal Housing Administration recommends 1 square foot of ventilation for every 300 feet of attic space.
It is expected that your roof will lose some granules. However, if you notice large quantities of granules in your gutter after heavy rainfall, it may indicate your roof is at risk of UV exposure and deterioration. If you have a new roof, this sign should not concern you because the granules are likely excess. However, if your roof is not new and you are just now noticing an increase in granules in your gutter, it is possible the shingles are about halfway through their lifespan.
If you notice green vegetation growing on your roof, it is important that you take action as soon as possible. Moss or algae can cause shingles to lift or curl, which will damage the integrity of the roof structure. An effective method to combat these intruders on your roof is to spray the problem areas with a mix of laundry-strength liquid chlorine bleach and water. Allow the solution to soak on the surface for 15 to 20 minutes, and then wash thoroughly with low-pressure water. To prevent moss or algae growth trim nearby tree branches that minimize sunlight, clear off debris, encourage air flow down the slope to dislodge debris, keep gutters clean, or add zinc or copper strips.
It is possible to repair a section of damaged shingles, and place new shingles over older, cracked shingles. However, some city ordinances and home insurance policies do not allow more than two layers of new shingles. Sometimes it is more cost-effective to replace the entire roof rather than a section, especially if the age of the roof indicates more repairs are likely in the near future.
Small holes in your shingles that allow light through into your attic will also allow moisture or even rodents into your home. You will need to determine if the area can be repaired or if replacement is the best option. Inspect your roof regularly. Look up in your attic or use binoculars outside.
