The roof is one of the most significant components of a home as it shields people and rest of the house from different weather conditions. A roof can protect a home for decades, even when it endures lots of wear and tear. Because of this, homeowners can easily take it for granted, and only a few conduct preventive maintenance.
If the roof damage is ignored and not addressed early, it can bring trouble to different parts of the house. Hence, it is crucial to watch out for developing roofing problems to prevent costly home and roof repairs.
Here are five signs that your roof needs repair:
- Aging roof
Like other products and items in the home, housing components also have life expectancies. According to a of the National Association of Home Builders (NAHB) and Bank of America Home Equity, the life expectancies of a home’s components depend on these factors: the quality of installation, maintenance, and weather conditions.
The NAHB found that roofs can last between 20-50 years, depending on the roofing shingles used for a home. Note that roofs made from slate, copper, and tile can last more than 50 years, while those made from wood shake, coal, and tar can be expected to last about 30 years.
Asphalt shingles are the most popular type of roofing materials used on New York homes. However, this type of roofing shingle, along with composition roof shingles and modified bitumen, might only last about 20 years.
An aging roof, which has been exposed to many extreme weather events, will eventually fail. Even when the roof’s quality looks suitable for its age, it is better to have a roofing contractor do a periodic inspection of its condition. However, it is more beneficial to replace it with newer and more robust shingles if it has reached its life expectancy.
- Mold and moss growth
Moss growth can look lovely and quaint on trees but not on the top of the roof. It can create cracks on shingles and produce gaps between tiles, damaging the roof’s structural integrity and causing roof degradation. When water gets in the interior part of the roofing through the cracks and holes, it can produce high attic moisture, helping bacteria and mold to thrive in certain areas.
- Sunlight coming through the roof
Sunlight coming through the roof is one of the most obvious signs that it needs repair. Roofing structures are supposed to cover people living in a home from weather conditions. If holes are present in the roof, it means the shingles either cracked or have gaps. If it can let sun rays in, then it can allow rainwater, which can be detrimental for the roof and the home’s interior.
- Water damage
Water leaks from the roof and the attic are another obvious sign that it needs repair. It is generally caused by missing tiles or broken seals under the roof flashing. However, in some cases, leaks are caused by complicated rooflines or improper installation.
If this sign is ignored, it can damage the attic and other parts of the house. It can stain the walls or ceiling, cause the flat surface to bubble or blister, or, worse, prompting the roof to collapse due to structural damage.
- Damage to different parts of the roof
The roof has different layers, including the roof frame, ice and water protector, underlayment, flashing, roof edge, and shingles; all of which have their functions to protect the house. But it can cause trouble to the whole roof and house’s quality when one layer gets damaged.
- Deformed roof shingles
The roofing shingles are the most visible layer of the roof and the first line of protection from different weather events. Although they can last for decades, shingles can degrade and deteriorate due to continuous exposure to the sun and extreme weather conditions, especially during winter and summer.
Shingles that deform, curl, or become brittle show signs of weathering or aging of the roof. When this happens, homeowners should consider investing in a new roof to protect their home further.
- Damaged flashing
Roof flashing is a thin metal material that is resistant to moisture and other weather conditions. It prevents water from seeping into the roof’s valleys, skylights, and vents to keep water out of the interior.
However, damaged flashing can cause irreparable damage to the roofing structure. One of the factors that can damage the flashing is the deterioration of the sealing material underneath it.
Likewise, having loose flashing can be a problem for the roof. It can let water enter the roof’s interior, producing moisture and providing a breeding area for mold and mildew. It can also cause extensive damage to the walls and ceilings of the house.
- Rotting underlay
Like the tiles and flashing, the underlay also keeps the water out of the roof’s interior and provides an added layer of protection from severe weather. It is a water-resistant material that is installed directly onto the roof deck.
Since it is under the tiles, a tear in the underlay can be hard to notice. Therefore, a leak in this part of the roof can go undetected, especially when it is only a tiny leak. However, remember that leaks can grow, which means water has seeped through the underlay and is starting to penetrate the attic, ceilings, and walls of the house. A sagging roof and rotting underlay can weaken the roofing structure’s foundation and cause it to collapse.
- Damaged mortar, ridge, and verge
Mortar is generally used as an adhesive when installing roof tiles and bedding for roof junctions such as ridges, the outer horizontal line where two roof areas intersect, and the verges, the roofing’s outer edges. These roofing materials are prone to exposure to extreme weather changes and building movements, causing it to degrade, crack, and dislodge over time.
Mortar has a limited lifespan. Thus, it requires attention and regular inspection. If the mortar gets damaged, it can affect the ridges, verges, and the rest of the roofing structure.
It is essential to improve the efficiency and prolong the roof’s lifespan as it is considered the first line of protection from weather events and conditions. With proper maintenance and inspection, homeowners can avoid damage or notice signs of roof damage early.
Some homeowners ignore these signs because they think repairing or replacing the roof is costly and time-consuming. However, disregarding damage on the roof can cause trouble in the house’s interior and cause extensive mold damage.
It is ideal to do repairs as early as possible to avoid further deterioration of the roof and expensive repairs or replacement. Hiring a professional roofing contractor can help inspect the quality of the roofing structure and ensure quality repairs.
