Detecting roofing problems early during a thorough structural inspection allows for appropriate remediation, potentially averting the need for an entirely new roof. Moreover, it enables building owners to plan for future maintenance and repairs, helping them to make the best use of their roofing investment.

Flashing is a thin layer of weather-resistant material installed in the joints and edges around roof penetrations like chimneys, skylights, and vent pipes. It redirects water away from vulnerable areas and prevents leaks, which can cause structural damage to the roof and underlying building materials.

A complete roof inspection includes a careful examination of the flashing to identify potential problems and keep the building watertight. During this process, the inspector checks the flashing for damage, loose sections, and the presence of gaps. If any of these problems are present, the inspector will take steps to repair them.

The flashing is typically made of metal, such as aluminum or galvanized steel. It’s often layered with caulking or roofing cement, which provides a strong seal. However, the sealant can break down from exposure to UV rays and moisture over time, leaving the flashing exposed to the elements. This is why regular roof inspections are so important.

During a roof inspection, the inspector will examine the flashing for cracks and rust. He or she will also ensure that the flashing is properly installed at all penetrations, e.g., that step flashing (required by asphalt, slate, and wood shingle manufacturers at sidewalls) is adequately extended up behind the exterior wall covering and that it forms a tight overlapping pattern with the roof deck to shed rainwater. Inspectors will also check that flashing at roof valleys is long enough to handle the heavy water runoff that occurs in these areas.

The inspector will also look at the flashing in other vulnerable areas of the roof, such as the eaves and rake edge. He or she will check for corroded flashing, loose pieces, and missing caulking or sealing. Loose flashing should be resealed or reattached to maintain the protective barrier.

In addition to inspecting the roof’s surface, a professional roof inspector will also examine the attic and interior ceiling for stains and other signs of moisture intrusion. He or she will also evaluate rafters, joists, and decking from the inside to check for moisture stains or structural weaknesses.

Shingles

The shingles are the roof’s outer layer and an important part of the overall roofing system. They protect the wood framing of a house and prevent moisture from damaging interior components. When a home’s shingles are in poor condition, it can lead to water leaks that damage the internal structure and cause mold growth. Regular inspections are important for identifying issues and maintaining a healthy roof.

When inspecting a shingle roof, look for cracks and creases along the edges of the shingles. Also, check for granule loss. This is an indication of aging and exposes the underlying material to UV rays, causing it to deteriorate faster.

Other signs of deterioration include dark patches on the roof and algae growth. If the shingles are damaged, it is likely that they will need to be replaced. In addition, you should look at the gutters and eaves for signs of rot. Rotted eaves are an indication that water is not being properly routed off the roof.

It is also a good idea to inspect the attic for water stains and damp insulation. A leaking roof can cause serious problems within the home and even structural damage to the framing. It is best to identify problems early on, before they become more severe, to minimize the cost of repair and replacement.

If a new roof is being installed, make sure that the installer is using proper installation techniques. Also, pay attention to the roof flashings, which should be fully secured to the deck and the shingle tabs. Also, be sure that the shingles are being installed according to manufacturer’s specifications.

A roof inspection is an important step in purchasing a home. A poorly maintained roof can be very expensive, and a home inspector can help you spot issues that may need to be addressed. Having the problems fixed before closing can save you money and hassle in the long run. It is also a good idea to negotiate with the seller to pay for any needed repairs during the home inspection period. This will allow you to close on the property quickly without any delays.

Gutters

While most roof inspections focus on the main components of the roof, it’s important to pay attention to gutters, soffits, and fascia as well. These accessories are necessary for maintaining the integrity of the roof and preventing water damage to the siding, foundation, or crawl space. During a roof inspection, home inspectors look for signs of damage or clogging that can prevent these devices from working properly.

A gutter is a trough or indentation along the edge of a roof that carries rainwater away from a structure, usually to a drain. Gutters are a good idea for structures that sit at the bottom of a slope, as they can help prevent erosion and other problems by channeling water away from the structure.

Home inspectors use a ladder to examine the condition of gutters and downspouts during a roof inspection. They typically check that the gutters are free of branches, leaves, and other debris, which can impede flow. They also look for rust, cracks, or sagging sections that may need to be replaced. They also check that the gutters are securely fastened to the fascia and downspouts.

Roofing professionals will often replace the gutter system when they do a roof replacement, which is one of the best times to do so since the contractor can take advantage of the opportunity to make any needed repairs to the siding and other components that are exposed when the old gutters are removed. Gutters are available in a variety of materials, including metal and seamless aluminum, which won’t rust or leak. A professional will calculate the size that meets a property’s needs and install it accordingly.

It is essential to inspect gutters for the presence of ice dams and other underlying issues. If they are not addressed, ice dams can cause moisture intrusion to the sheathing of a roof and may require additional repairs or even replacement. In addition, if the gutters aren’t installed correctly, they can clog or become flooded with water, causing overflow and potentially leaking into the house. Professional roofers can address these issues, as well as evaluate shingle damage, and recommend any necessary repairs or replacements.

Vents

The vents of a roof are more than just an architectural detail; they play a significant role in attic ventilation, which in turn impacts the lifespan and performance of a house’s roof. A well-functioning roof vent system ensures that fresh air flows into and out of the attic, helping to regulate temperature and preventing moisture buildup and mold.

Exterior vents are found on the ridge or peak of the roof and can be made of a variety of materials. Continuous/ridge vents run the entire length of the ridge or most of it, and are used for exhaust, allowing warm air that rises to the attic to escape. Box vents, on the other hand, are placed in locations that are not visible from the front of the home, blending in with the rest of the roofline and preserving aesthetics.

During your roof inspection, be sure to check all exterior structural elements such as pipes and equipment for cleanliness and damage including cracking paint, rust, moss or fungus. Be especially sure to check for sagging pipes, deflected supports and parts digging into the roof membrane, which are signs of deterioration and leakage.
