When Might an Asphalt Roof Be Beyond Repair?

An asphalt roof typically presents repairable issues; however, there are rare instances when repairs aren’t feasible. One such scenario arises when the roof lacks core vents, predominantly found in older structures where concrete substrates were utilized with a screeded covering. This practice aimed to establish roof slopes aiding rainwater drainage.

Understanding the Core Vent Dilemma 

In the absence of core vents, water trapped within the screed either infiltrates the property or accelerates the deterioration of the mastic asphalt membrane. Core vents play a pivotal role in modern roofing systems by facilitating the drying of screeds and enabling ventilation, thereby mitigating water ingress and preventing membrane degradation.

Consequences of Core Vent Deficiency 

Without core vents, the inherent challenge of water seepage persists, jeopardizing the waterproofing integrity of the structure or hastening the degradation of the asphalt membrane. In such circumstances, opting for a new asphalt roof becomes the most viable solution to avert further damage and ensure long-term structural resilience.

Addressing Core Vent Absence 

When faced with a roof lacking core vents, the prudent course of action entails strategic planning for the installation of a new asphalt roof equipped with core vent systems. This proactive measure not only addresses the immediate issue but also safeguards against future structural vulnerabilities, enhancing the longevity and performance of the roofing system.

Common Causes Requiring Asphalt Roof Repair

Bumps: Unveiling the Underlying Moisture Woes 

Bumps on an asphalt roof surface signal a deeper concern—moisture entrapment beneath the membrane. As moisture seeks an escape route, it manifests as these protrusions. Addressing bumps promptly is crucial to prevent exacerbation of water ingress, averting potentially severe repercussions.

Expanding Further: 

Moisture entrapment catalyzes a domino effect, initiating a series of consequential damages. Therefore, swift intervention upon spotting bumps is paramount to preempt further structural degradation.

Blistering: Unveiling the Multi-faceted Dilemma 

Blistering, akin to bumps, arises from moisture entrapment beneath the asphalt membrane. Unlike singular bumps, blistering manifests as clusters, reminiscent of the skin condition. The resemblance serves as a visual cue for prompt remediation, mirroring the urgency in addressing this issue as with bumps.

Delving Deeper: 

Understanding the nuanced differences between bumps and blistering underscores the complexity of moisture-related damages, necessitating tailored remedial actions for each manifestation.

Cracks And Splits: Pondering Over Pathways to Peril 

Cracks and splits epitomize grave vulnerabilities in the waterproofing integrity, exposing the roof to the perils of water ingress. These fissures can manifest through various mechanisms, including the exertion of pressure from moisture-laden bumps or external impacts.

Exploring the Causes: 

Dissecting the diverse origins of cracks underscores the multifaceted nature of asphalt roof vulnerabilities, necessitating a comprehensive approach to repair and maintenance.

Slumping: Unraveling the Seasonal Struggles 

Slumping ensues during scorching summer months, as relentless solar radiation subjects the asphalt to deformation. Particularly problematic around lead flashing and upstands, slumping creates avenues for water intrusion, underscoring the imperative for preemptive measures such as solar reflective paint.

Shedding Light: 

Highlighting the efficacy of solar reflective paint emphasizes its pivotal role in mitigating the adverse effects of thermal stressors, fortifying the asphalt against seasonal adversities.

Failing Flashing: Navigating the Pitfalls of Conduction

Lead flashing, while essential, poses challenges due to its thermal conductivity, predisposing the underlying asphalt to slumping. Moreover, deterioration of mortar or thermal-induced expansion can compromise flashing integrity, necessitating vigilant maintenance to avert consequential damages.

Unveiling the Risks:

Scrutinizing the vulnerabilities inherent in lead flashing underscores the intricate interplay between roofing components, accentuating the imperative for holistic repair and upkeep protocols.

Failing Upstands: Tackling Structural Integrity 

Upstands, vulnerable to detachment or mortar degradation, demand meticulous attention to prevent structural compromise. Whether due to inadequate installation or aging, addressing failing upstands is indispensable to uphold roofing integrity.

Focusing on Solutions: 

Navigating the intricacies of upstand failures underscores the importance of precision and vigilance in repair endeavors, safeguarding against potential structural hazards.

Oil Damage: Confronting Chemical Erosion 

Oil residues pose a significant threat to asphalt integrity, necessitating immediate remediation to avert consequential deterioration. Employing specialized techniques such as the ‘hot poultice’ method is indispensable in restoring affected areas to their former resilience.

Addressing the Menace: 

Highlighting the urgency of oil damage repairs underscores the proactive stance required to preserve asphalt longevity, mitigating the deleterious effects of chemical erosion.

Cracked Render: Guarding Against Indirect Threats 

Render cracks, while seemingly unrelated to the roofing system, pose a latent threat to substrate integrity. Left unattended, these fissures facilitate water ingress, culminating in potential leaks and structural compromise.

Mitigating Secondary Risks:

Acknowledging the ripple effects of render cracks underscores the holistic approach required in safeguarding against indirect roofing vulnerabilities, reinforcing the importance of comprehensive maintenance practices.

Split Asphalt Collars: Safeguarding Against Infiltration 

Mastic asphalt collars, vital for sealing soil vent pipes, are susceptible to displacement due to thermal fluctuations. Addressing defective collars promptly is imperative to prevent water infiltration and mitigate the risk of consequential damages.

Ensuring Protective Measures: 

Emphasizing the critical role of intact asphalt collars underscores the proactive measures essential in fortifying roofing systems against infiltration threats, accentuating the significance of vigilant maintenance practices.

Roof Maintenance Tips for Prolonging Lifespan 

Regular Inspections: 

Regularly examining your roof’s condition is pivotal in detecting potential issues early on. Utilize binoculars to inspect from the ground or, if safe, climb up for a closer look. Pay attention to shingles, flashing, and any signs of wear or damage.

Cleaning Gutters:

Clogged gutters can lead to water backup, causing damage to your roof and home interior. Clean gutters biannually, or more frequently if surrounded by trees. Remove debris by hand or with a gutter scoop, and flush with water to ensure proper drainage.

Trimming Overhanging Branches:

Overhanging branches not only pose a risk during storms but also promote algae and moss growth on your roof. Trim branches regularly, ensuring they’re at least 10 feet away from your roof. This prevents debris accumulation and reduces the risk of roof damage.

Professional Inspection and Maintenance: 

While DIY inspections are beneficial, hiring a professional roofer for a thorough assessment is recommended annually. Professionals can identify hidden issues and perform necessary repairs or maintenance, prolonging your roof’s lifespan and minimizing potential costly damages.
