A roof protects a building’s interior from the elements. Signs of a faulty roof include water stains in ceilings and walls, mold and mildew, and peeling paint.

Check the flashing around chimneys, vent pipes, and skylights for cracking or loosening. Look for deteriorating caulk and sealant, and remove moss or fungus. Contact Five Star Roofing and Contracting for professional help.
The flashing is an essential component that channels water away from the vulnerable parts of the roof. It is a thin strip of material, usually galvanized steel, installed around various roof penetrations, such as chimneys, vent pipes, skylights and other accessories. The flashing is designed to overlap the roofing materials and provide a tight seal to prevent water leaks. The flashing is subject to wear and tear due to the elements as well as to the installation itself, so it is important to inspect it regularly for signs of damage or improper function.
If you notice any of the following signs of flashing problems, it’s time to call in a professional:
Leaks
The most obvious sign that the flashing isn’t performing its job is noticing water stains on ceilings and walls. This is because these stains are the result of water seeping through gaps where the flashing is no longer providing a secure seal. Look for areas where water pooling is evident, especially around the vents, chimneys, and valleys of the roof. Check for rust and corrosion on the flashing as well. This is an indication that it is corroding and may soon fail.
Pooling water can accelerate the damage to the flashing and the roofing materials surrounding it. It can also lead to the development of mold and mildew as well as structural issues. An experienced roofer will inspect the area and re-secure or replace the flashing as needed.
When the flashing is damaged, it can no longer provide adequate protection against rainwater and snow melt. It is therefore essential to inspect the condition of the flashing periodically, especially after heavy rainstorms and harsh winter weather.
Aside from checking for physical damage to the flashing, a professional will also examine the shingle and roofing materials for deterioration or leaks. They will also look for any signs of debris in the drains, such as leaves, sticks and other organic material. This can clog the drains and cause water to build up on the roof, leading to rot and mold. If any drains are found to be blocked, they will need to be unclogged immediately.
Inspect the Structure
A professional roof inspection should also examine the structure of the roof to look for signs of deterioration. This will include checking for structural damage such as cracking or leaking, rot, rust, mold and mildew, water stains and the condition of the support trusses and beams. This should be done regularly to ensure that the roof is not at risk of a collapse.
This is especially important if the roof has been damaged by a weather event. For example, a roof that has sustained damage from hail can develop leaks and other problems that should be inspected for immediately. These problems will often grow and escalate into a much more costly problem if they are left untreated.
During a typical roof inspection the inspector will examine all the materials on the surface of the roof, such as curling or brittle shingles and corroded metal panels. They will also check for sagging of the roof, which can indicate that it is nearing the end of its life and should be replaced. The inspector will also inspect for any penetrations on the roof (such as pipes, chimneys, vents etc) to make sure that the flashing has not been damaged. Most leaks occur at these penetration points, as they are often exposed to a lot of stress.
Another area of focus during a roof inspection is the seams and membrane. These areas are particularly vulnerable to leaks, as they are often the sites of accessories built into the roof such as air vents, skylights and air conditioner units. The membrane is also subject to harsh UV rays which can break down the material over time.
The roof inspector will also check for any unsealed laps, both on the vertical and horizontal parts of the flashing. This is a common mistake that contractors make, as it allows the elements to penetrate into the roof. The inspector will also examine the expansion joints and make sure that they are properly terminated with rubber bellows.
Finally, the inspector will look for any debris on the roof. Debris can restrict drainage, accelerate membrane deterioration and create a tripping hazard for future maintenance workers. This is especially important if the roof is adjacent to trees where the foliage should be kept well clear. It is also a good idea to post safety warnings on the roof, especially where there are electrical, hazardous chemicals or hot equipment.
Inspect the Vents and Skylights
Before climbing up to the roof, a thorough visual inspection should be conducted. Look for obvious signs of damage, such as missing or damaged shingles and sagging areas.
Pay special attention to the chimney, vents, skylights and any other roof penetrations such as pipes or equipment. If they are not installed properly, they can cause water to leak into vulnerable areas of the roof. Inspecting the flashing and caulking around these components is also important, as they can be the source of leaks. Look for cracks, gaps and abrasions, as well as the presence of mold, mildew and moss.
The interior of the building is also a critical part of any roof maintenance inspection. Look for water-related damage such as mold or mildew, water stains on walls and ceilings, and damp insulation or wood rot. Also, examine the attic for a dry and well-ventilated environment. Look for sagging or other structural damage and make sure there are no leaks through the attic floor or a sagging roof deck. Finally, inspect trusses and beams for signs of stress or rot.
A thorough material inspection will include a close examination of all the roofing materials used on a roof, including the underlayment and membrane. Inspect these for signs of leaks or cracks, and for any insect infestations or other damage. Keeping up with regular maintenance and inspections can help to identify potential problems before they become severe, thereby extending the lifespan of the roofing system.
A good preventive maintenance program should incorporate both the interior and exterior of a roof, along with all its components. This type of inspection will allow the owner to spot problems before they become expensive and complex repairs. It can also extend the life of a roof and keep any roofing warranties valid. However, it is essential to remember that performing these types of inspections requires the use of a ladder, and proper safety precautions should be taken. In addition, it may be necessary to contract a professional roofing contractor for more extensive or complicated repairs. This will ensure that the job is done correctly and safely.
Inspect the Gutters
Gutters play a key role in directing water away from the roof and foundation. A regular inspection and cleaning can ensure they are functioning properly and preventing water damage. If a gutter becomes clogged, it can lead to water pooling on the roof and saturating the soil surrounding the house. This can cause leaks and rot. Gutters also need to be free from debris like leaves and twigs to facilitate water flow. A roofer should also check for any downspout blockages, which can prevent proper drainage and lead to clogs. Downspouts should also be angled correctly to allow for water to flow down and away from the house.
In addition to the gutters, a roofer should inspect and repair any cracks or gaps around vents, chimneys, skylights, and other flashing. These can allow moisture into the home, which leads to mold and wood rot. In some cases, these problems may not be immediately obvious, but they can become progressively worse over time if not addressed.
Another important part of a roof inspection is to look for shingle wear. Asphalt shingles contain gravel-like granules that gradually break off and fall into the gutters. If the granules are present in large amounts, it is likely that shingles are getting old and are starting to fail. Having the granules removed and replaced will help to extend the life of the roof.
A roof inspection can be done by the homeowner, but it’s best to leave a professional inspection and maintenance to a roofing company with the necessary training and equipment to perform a thorough assessment. A DIY inspection can help to spot the most obvious issues, but a professional can provide a more comprehensive assessment and recommend any necessary repairs.
