    5 reasons why should you have a professional roof inspection to assess heavy storm damage.

    Whangarei is renowned for its scenic landscapes and coastal allure, is no stranger to the capricious nature of weather, particularly during heavy storms. As a homeowner in this breathtaking region, it’s vital to understand the potential impact of severe weather on your property, especially your roof. Opting for routine professional roof inspections, particularly after heavy storms, stands out as one of the most effective ways to ensure the safety of your home and loved ones. In this blog, we’ll delve into the reasons why investing in Watt Roofing is not only prudent but also a wise decision.

    Moss and Algae Growth:

    In the humid climate of Northland, moss and algae flourish on roofs, trapping moisture and compromising its integrity. Moss, with its root-like structures, can lift shingles, resulting in water pooling and potential damage to the underlying structure. Furthermore, these organisms hasten the deterioration of roofing materials by consuming organic matter, diminishing their effectiveness over time. If you notice the presence of moss or algae, it is crucial to take immediate action through thorough cleaning and treatment to prevent further deterioration. In severe cases, such as extensive damage or deterioration, replacing affected sections or even the entire roof may be necessary to restore its functionality effectively. Regular inspections, conducted by Watt Roofing, play a vital role in early detection and addressing growth, thereby prolonging the lifespan of the roof and ensuring the integrity of your home.

    Corrosion on Metal Roofs:

    Coastal living in Northland not only exposes roofs to salt-laden air but also subjects them to the challenges posed by the region’s weather patterns. The high humidity prevalent in the area contributes to moisture buildup on roofs, creating an environment perfect to the growth of moss, algae, and mold. Besides detracting from the roof’s aesthetic appeal, this growth can also compromise its structural integrity over time. Furthermore, frequent rainfall increases the risk of water penetration through cracks or gaps in the roofing material, leading to leaks and water damage inside the home. Exposure to intense sunlight can also contribute to the deterioration of roofing materials, causing them to become brittle and cracked. Taken together, these factors present significant challenges to the durability and longevity of roofs in Northland. Thus, it is important to proactively maintain and repair your roof timely to prevent potential damage and ensure the continued protection of homes against the elements. For reliable roofing services and proactive maintenance tailored to Northland’s unique climate, homeowners can trust Watt Roofing to provide expert solutions and ensure the long-term integrity of their roofs.

    Leaks and Water Stains:

    Persistent leaks or water stains, particularly evident after heavy rainfall, are clear indicators of a deteriorating roof in Northland’s climate, characterised by frequent precipitation. These signs indicate that the roofing materials have been compromised, allowing water to penetrate the roof’s protective barriers. It’s very important to promptly address such issues to prevent further harm to the roof’s structure and the interior of the home. Ignoring these problems can result in extensive damage, including the rotting of roof deck, corrosion of support beams, and the growth of mould. In severe instances where leaks persist or are widespread, simple repairs may not be enoug. A complete roof replacement may be required to ensure sustained protection and structural integrity. Expert companies like Watt Roofing highlights the importance of prioritising the resolution of persistent leaks or water stains. Regular roof inspections conducted by Watt Roofing, helps in early detection and resolution of these issues to reduce the risk of extensive damage and costly repairs down the line.

    Wind Damage:

    Northland is prone to strong winds, posing a significant risk to the structural integrity of roofs in the area. Following a storm, the presence of lifted or missing shingles becomes a crucial indicator that the roof may be exposed and vulnerable to further damage in subsequent storms. When shingles are lifted or blown off, it exposes the underlying roof structure to the elements, increasing the likelihood of water infiltration and structural damage. Moreover, missing shingles create weak points through which wind can easily penetrate, escalating the risk of further shingle loss and additional damage to the roof’s structure. Consequently, homeowners should consider lifted or missing shingles as a red flag and promptly address these issues to reinforce their roof’s resilience and minimise the risk of extensive damage during future storms. With professional guidance from Watt Roofing, homeowners can ensure detailed inspections and effective repairs to safeguard their roofs against Northland’s strong winds. Regular maintenance and proactive measures are essential for preserving the durability and longevity of roofs in the region.

    Brittle or Cracked Shingles:

    Continuous exposure to the intense UV rays of the sun can have detrimental effects on shingles, leading to brittleness or cracking over time. The asphalt composition of shingles can degrade under prolonged UV radiation, resulting in a loss of flexibility and resilience. Therefore, shingles become more susceptible to damage, compromising their ability to provide adequate protection for the roof and the underlying structure of the home. Visible signs of wear, such as curling, blistering, or granule loss, serve as warning that the shingles may no longer effectively shield the roof from environmental elements. Cracked or deteriorated shingles create openings through which water can infiltrate the roof, potentially causing leaks, water damage, and structural issues. Hence, homeowners in Northland should diligently inspect their roofs for signs of wear and consider replacing worn shingles to uphold the roof’s integrity. Seeking professional guidance and assistance from Watt Roofing ensures quality replacement of deteriorated shingles, thereby extending the roof’s lifespan and preserving the structural integrity of the home.
