Our roof system can last from 20 to 50 years depending on the materials used. But they can deteriorate because of improper maintenance, normal wear-and-tear, and severe weather conditions. This is why roofs need regular inspection during the fall and spring season. You can do self-checks from time to time. But a professional roof inspection Sydney expert is highly advised. They are knowledgeable enough to spot potential problems. They can also recommend the best solutions to such issues.
There are three main objectives of a roof inspection. First, it aims to determine if your roofing system is performing well according to its intended function. Second, it also aims to identify any signs of aging, damages, and potential hazards to your roofing system. Last, in case the roof inspection detects any repairs needed, it aims to quickly resolve the issue to prevent further costs and damages. For a better idea, here is the process of roof inspection in a nutshell.
Check the roof covering. The roof covering is your roofing system’s 1st line of defence. As such, it is the most exposed component of your roofing system. The first step to a roof inspection is to have a visual check on the roof covering. Roof inspectors will try to spot signs of water intrusion in the attic. They will also look for debris, physical damages, and structural deformation.
Check the fasteners. A typical roofing system may include thousands of fasteners. They are used to secure the insulation and roofing membrane to the roof deck. The 2nd step to roofing inspection is checking if these fasteners are still in good condition. Roof inspectors will try to check if there are any head damages or tears on the shingles. They will also check if the fastening quality is rusting away. Rust can cause holes for water to seep or winds to blow off shingles.
Check the deck sheathing. Deck sheathing is the structural subfloor of your roofing system. It carries the strength of a roofing system. The 3rd step to roofing inspection is to determine if the deck sheathing was properly installed or still in place. They may try walking in the roof to gauge its structural integrity. Although walking on the roof is not a requirement for a roofing inspection. Furthermore, roof inspectors will check if the fasteners on the deck sheathing are still intact and properly spaced.
Check the slope and underlayment. The slope is the inclined position of a roofing system. While the underlayment is what lies in between the shingles and the deck sheathing. Underlayment is installed based on the roof slope. This is the 4th step to a roof inspection and is somewhat hard to do. Roof inspectors don’t need to tear the shingles to check the underlayment. What they need to check is the slopes on the roof. A flat roof signals a roofing problem. The absence of slope means that water has penetrated your roofing system.
Check the ice barrier. Not all roofing systems have ice barriers. They are waterproof roof underlayments commonly placed on eaves, edges, overhangs, and valleys of a roofing system. These areas are most vulnerable to ice dams and rainwater driven by strong winds. The purpose of ice barriers is to protect the roofing system from any water leaks as the ice dams melt or as strong winds blow water inward the roofing system. The 5th step to a roof inspection is to check if the ice barriers are still performing their function. The roof inspector will thoroughly check the edges of your roof. Any discoloration, mould, or rotting on the edges is a sign that your ice barrier may no longer be working properly.
Check the drip edge. The 6th step to a roofing inspection is checking the drip edges. They are L-shaped metal sheets that direct water away from the fascia of the roofing system into the gutter. Roof inspector commonly takes a picture of the drip edges while they go up to the roof. From the picture taken, they can verify if there are damages to these parts of the roofing system.
Check the roof valley flashing. The roof valley flashing covers the area where two roof slopes meet. They are designed for water to flow down on the roof slopes. The 7th step to a roofing inspection is to check if the roof valley flashing is still fastened well between the slopes. Fading or rusting can also signal that your roof valley is aging. If they are very prominent, a roof inspector may recommend a replacement.
Check the flashing areas. Flashing areas are thin metal sheets that direct water away from critical areas of your roofing system. The 8th step to a roofing inspection is to check if these metal sheets are properly fastened and steadily placed on your roofing system. Improperly placed flashing to your roofing system can cause water leaks, mould formation, and pest infestation inside your homes.
