If you’ve been thinking about getting your roof replaced, this article is for you!
We’re going to take a look at what makes a roof still good and how to tell if yours might need to be replaced.
How to tell if your roof is good or bad?
To determine if your roof is in good or bad condition, you should look out for various signs such as missing or damaged shingles, cracks or leaks, sagging or uneven roofline, wear and tear on roofing materials, algae or moss growth, excessive granules in gutters, sunlight-visible through roof boards, water stains on the interior ceiling, and weak or broken roof decking.
A more thorough evaluation can be done by a professional roof inspector who can assess the condition of the roof structure, ventilation, and drainage systems, as well as check for signs of wear and tear, and other potential problems that could affect the roof’s overall performance and longevity.
A well-maintained roof should last for many years, but various factors such as weather, age, and maintenance can impact its performance over time.
A roof that is damaged or poorly maintained can lead to leaks and water damage, which can cause serious damage to the structure of the building and also be a health hazard due to mold growth.
Regular roof maintenance and inspections are crucial for ensuring that your roof is in good condition and can provide long-lasting protection for your home or building.

Get multiple quotes
Contact several reputable roofing contractors and get quotes for the cost of a new roof. Make sure you understand the scope of work and materials included in each quote.
Check for references and credentials
Before hiring a roofing contractor, check for references and credentials. Look for a contractor with a good reputation, proper licensing, and insurance.
Review contracts and warranties
Before signing a contract with a roofing contractor, review the terms and conditions and make sure you understand the warranty offered on the materials and workmanship.
Prepare your home
Prepare your home for the roofing work by removing outdoor furniture, plants, and other items that may be in the way. You may also want to cover outdoor fixtures or take other steps to protect your home during the roofing process.
Communicate with your contractor
Communication is key when working with a roofing contractor. Be sure to discuss your expectations and any concerns you have, and be available to answer questions and provide guidance throughout the roofing process.
Consider financing options
If the cost of a new roof is a concern, consider financing options, such as a home improvement loan, a personal loan, or a line of credit.
Inspect the work
After the roofing work is completed, inspect the work to ensure that it was done properly and that you are satisfied with the results. If you have any concerns, address them with the contractor before the warranty period ends.
How can I tell if shingle granules are missing from my roof?
Shingle granules are small, rounded particles that protect the asphalt in your roofing shingles. To determine if shingle granules are missing from your roof, inspect your roof’s surface and gutters for evidence of small, gritty particles.
You can also look for bald spots on the roof where shingles appear to be missing granules and have a matte or smooth appearance compared to the surrounding shingles.
What are some signs of hail damage on a roof?
Hail damage on a roof can manifest in several ways. Look for dents or cracks in metal surfaces, such as metal vents or flashing. On asphalt shingles, hail damage can appear as random, circular bruises or cracking. Also, missing or cracked granules, which can be seen in gutters or downspouts, are another indication of hail damage to the roof.
What causes roof leaks?
Roof leaks can be caused by a variety of factors, including poor roof design or installation, aging or worn materials, and exposure to severe weather conditions. Common causes of roof leaks include missing or damaged shingles, clogged gutters or downspouts, and damage to flashing or seals around roof penetrations.
Regular roof maintenance, such as clearing debris, inspecting for damage, and repairing any issues promptly, can help prevent roof leaks and prolong the lifespan of your roof.
What should I do if I find rust on my gutters?
Rust on gutters can indicate that the metal is wearing down and may soon become prone to leaks and other types of damage.
To address rust on your gutters, it is recommended to clean the affected areas and apply a rust inhibitor to prevent further corrosion.
- Wire brush: Use a wire brush to scrape off loose rust and debris.
- Sandpaper: Use sandpaper to sand down the rusted surface until it is smooth and free of rust.
- Vinegar and baking soda: Mix vinegar and baking soda to create a cleaning solution that can be used to remove rust from the gutters.
- Rust remover solution: Use a commercial rust remover solution, following the manufacturer’s instructions, to clean the rusted areas.
- Steel wool: Use steel wool to scrub away rust, being careful not to damage the gutter material.
- Power washer: Use a power washer to blast away the rust and any other debris on the gutters. Be careful not to use the power washer on the shingles. They may cause damage to them. Focus the water on the gutter system only.
If the rust is extensive and cannot be removed, the affected sections of the gutters may need to be replaced to ensure proper function and protect your home from water damage.
How do I check for moisture in my attic?
Checking for moisture in your attic involves a visual inspection for water stains, mold growth, or peeling or bubbling paint on the attic’s walls or ceiling, which can indicate that there is water building up.
A less popular method is to use a moisture meter to measure the moisture content of the materials in the attic can also be helpful, especially in areas with insulation.
As a general rule, moisture levels read on a moisture meter between 5% to 12% are considered normal, while up to 17% are still within acceptable limits.
Look for signs of condensation, such as water droplets or puddles on the roof deck or underside of the roof sheathing. If any signs of moisture are found, it is important to address the issue promptly to prevent further damage and ensure the health and safety of your home.
How often should I have my roof inspected?
It is recommended to have your roof inspected at least once a year, or after major weather events such as heavy rain, hail, or high winds, to ensure it is in good condition.
If your roof is older than 15 years, it may be necessary to have it inspected twice a year.
An annual or biannual roof inspection can help identify potential problems early and prevent minor issues from becoming major ones.
Having a professional inspect your roof can give you peace of mind, as they will be able to assess the overall condition of your roof, its ventilation, and insulation, and advise you on any necessary repairs or maintenance.
It can also prolong the life of your roof and help you plan for necessary repairs or replacements before they become critical and costly.
How much does a roofing inspection cost?
The cost of a roof inspection can vary widely based on several factors, including the size of your roof, the complexity of the roof’s design, and the experience and qualifications of the inspector.
On average, a professional roof inspection can cost anywhere from $120 to $300, although some inspectors may charge more or less.
Keep in mind that the cost of the inspection is a small investment in comparison to the cost of repairs or replacement if a problem with your roof is not detected and addressed on time.
Some inspectors may offer discounts for repeat customers or for customers who also need other services, such as roof repair or replacement.
