Expect optimal performance and longer life span out of your asphalt shingle roofing system if it is properly installed. But how can you tell if this is the case? Your trusted roofing contractor, V. Nanfito Roofing & Siding, walks you through the hallmarks of a properly installed asphalt shingle roof.
The roof underlayment serves as the secondary barrier in case water penetrates through the shingles. Roofers utilize quality synthetic or felt underlayment, with the seams properly overlapping to prevent water ingress and secured firmly to the decking without wrinkles or gaps.
Flashing is critical for preventing leaks around roof penetrations and intersections. These include areas around chimneys, vents, valleys and wherever the roof meets a wall. Properly installed flashing should be made from durable and corrosion-resistant materials, correctly integrated into the underlayment and shingle layers and sealed with appropriate sealants.
Drip edges are installed along the eaves and rakes of the asphalt shingle roofing system, ensuring proper water drainage away from the fascia and other structural components. A proper roof installation should involve continuous and well-fastened drip edges integrated with the underlayment and shingles to prevent water intrusion along the edges.
Proper ventilation is crucial for maintaining a balanced airflow and preventing damage from trapped heat and moisture. A high-quality installation should include ventilation systems such as ridge vents, soffit vents or gable vents to provide balanced intake and exhaust. Adequate ventilation prevents moisture buildup, which can lead to rot, mold and ice dam formation.
Asphalt shingles should be installed according to the manufacturer’s guidelines, including nail placement, overlap patterns, spacing and required ventilation. Proper shingle installation should also involve using quality fasteners and sufficient adhesives to ensure the shingles remain secure and watertight, even during adverse weather conditions.
An ice and water shield can protect the roof from ice dam formation and water infiltration in cold climates. Properly installed ice and water shields should be applied to vulnerable areas, like the lower edge of the roof deck, valleys and around penetrations, creating a watertight seal that bridges gaps and prevents leaks.
The clean and professional appearance is a hallmark of a properly installed asphalt shingle roof. This includes straight lines, well-cut shingles, clean valleys, properly placed and secure ridge caps and well-sealed penetrations. A balanced and uniform appearance signifies high-quality workmanship.
