Your roof keeps your home safe from the elements and often represents a substantial financial investment. Keeping up with regular maintenance will extend your roof’s life span and prevent costly repairs. In this article, we’ll go over maintenance tips for common roofing materials and help you identify potential problems that require a professional roofer.
Types of Roofing Systems and Materials
The specific maintenance your roof needs will largely depend on its material.
- Asphalt shingles: The most common residential roofing materials are asphalt shingles. They’re cost-effective, easy to install, and available in a wide range of colors. Unfortunately, they also have short life spans. Depending on the quality and type of shingles, they may last anywhere from 10 to 30 years.*
- Metal: Available as panels, sheets, or shingles, metal roofs are highly durable and stand up well to inclement weather. Most metal roof options are substantially pricier than asphalt shingles, but they don’t require frequent replacement. Steel and aluminum roofs last 40 to 70 years, and premium metal roofs, such as those made of copper and zinc, can last up to 100 years.
- Tile: Roof tiles are usually made of clay, though concrete or composite tiles are also available. Clay tile roofing is prized for its curb appeal and longevity. It can last 50 years or more, but it’s also costly to install and repair.
- Slate: Natural slate makes for an incredibly sturdy but heavy roofing material. Most roofs need to be structurally reinforced before slate can be installed. Slate is often the most expensive roofing option but can last up to 200 years.
- Wood: Available as rough-cut shakes or smooth-cut shingles, wood gives any roof a beautiful, traditional look. While wood roofing isn’t as expensive to install as some other roofing materials, it has very high maintenance needs to prevent rot and water damage. Properly maintained, wood shakes and shingles last about 30 years.
- Flat roofs: To prevent drainage issues, flat roof surfaces require specialty materials. Rubber membranes are common, as are modified bitumen sheets and layers of tar and gravel. Depending on the roofing material, a flat roof can last 20 to 50 years.

Importance of Regular Roof Inspections and Maintenance
The roof’s surface prevents precipitation, high winds, and debris from damaging your home’s interior and structural components. Thus, following a roof maintenance program not only keeps your roof looking good, but it also extends your home’s life span. Most roof issues are caused by water penetrating surface materials and causing damage underneath, so many maintenance tasks are geared toward ensuring water resistance and spotting problems early. Even a small leak can cause widespread rot, mold, or sagging if it continues unchecked.
Maintenance Tasks
An important part of routine maintenance is the roof inspection. After your roof is five years old, you should hire a professional to do a thorough annual inspection, especially if you live in an area with severe weather. You should also do more frequent periodic inspections on your own from the ground and keep an eye out for signs of damage. If you have access to your attic, check for signs of leaks, such as musty odors, water stains, or bulging or peeling paint.
Cleaning is another important facet of maintenance. Roof debris looks unsightly, and it can also trap water on the roof and cause water damage. Roof moss and algae can also begin to degrade surface materials, particularly in humid climates, and should be removed. You can hire professional roof cleaners or do the job yourself, but take care to prioritize safety and refrain from harsh cleaning. High-pressure water will damage most roofing materials, including asphalt shingles.
Other common maintenance tasks include trimming tree branches so they don’t overhang your roof and ensuring that seals around roof penetrations, such as skylights, vents and chimneys, are in good shape. Check that the chimney mortar is intact and that the chimney isn’t cracked or leaning. Make sure any vents remain unobstructed to allow proper airflow. Finally, ensure gutters and downspouts are clear and in good condition.
Maintenance Frequency
As mentioned, once you’ve had your roof for five years, you should have a professional inspect it annually. You should also do your own inspections twice annually and check for roof damage after severe storms. Roof cleaning is usually an as-needed task, but gutter cleaning should be done at least twice per year or more frequently if your gutters are prone to clogging.
Some roofing materials, such as wood shingles and flat roof membranes, require periodic resealing. For flat roofs, the frequency depends on the sealant’s quality—inexpensive acrylic will need to be reapplied every 10 years, but high-end silicone may last up to 50 years. Wood roofs, on the other hand, usually need water-resistant and fire-resistant recoating every one to three years.
Signs a Roof Needs Repair or Replacement
When you inspect your roof, look for the following signs that roof repair may be necessary.
- Attic leaks
- Exposed or loose roofing nails
- Missing, cracked, or curling shingles
- Missing shingle granules (possibly clogging gutters)
- Rusted, peeling, or missing flashing
- Water stains on exterior walls
- Worn or cracked pipe boots
No matter what roofing material you have, it will eventually need replacing. Here are some signs that you may need a full replacement.
- Leaks are numerous or large.
- Many shingles are damaged, worn, or missing granules.
- There is extensive water damage in the attic.
- The roof deck appears to be sagging or buckling.
- Your shingle roof is more than 15 years old.
Hiring a Professional Roofer
While dedicated homeowners may be able to patch small leaks themselves, we recommend hiring a licensed roofing contractor for repairs and replacements. Professional roofing services know how to keep themselves safe and maintain your roof’s structural integrity. You may also void any warranty on your roofing material by performing repairs yourself. Steep roofs and multistory homes pose safety risks, so for peace of mind, hire a roofer instead.
When you hire a pro, you’ll pay for any necessary materials as well as the labor to install them. Here are the average costs for professional roofing contractors.

Our Recommendation
No matter what type of roof you have, routine inspections and maintenance are vital to protecting your investment in your home and extending your roof’s life span.

This prevents more costly problems down the line.
