Why Roofing Maintenance Is Important

Performing regular roofing maintenance allows for early problem detection. Repairs can then be made before they become serious.


Look for shingles that are cracked or missing, especially after a hailstorm(opens in a new window), excessive wind, or an ice dam. Also, inspect the caulk around flashing and vent pipes and note areas with moss. For professional help, contact Roofing Corpus Christi.

Wood shingles and shakes can last for decades with planned maintenance, but the material is vulnerable to the effects of sun exposure and rainfall that speed degradation. The woods of the preferred shingle and shake species—western redcedar (Thuja plicata), coastal redwood (Sequoia sempervirens) and bald cypress (Taxodium distichum)—are inherently more durable than other timbers because their cores contain compounds that resist moisture uptake. These materials, however, are still subject to deterioration from environmental stresses including UV radiation, changes in the wood’s moisture content and leaching of natural preservatives.

Degradation is more rapid on wet, warm roofs because water seeps into the structure and cools the wood, lowering its strength. Other factors that influence a wood shingle or shake roof’s life include the slope of the roof, its shading by overhanging trees, the amount of air circulation available to facilitate drying and the quality of the original wood.

Fungal spores that float through the air and move with moisture settle on a wood shingle or shake surface and gradually grow inside it. As the fungi mature, they degrade the structural components that give a shingle or shake its strength. The spores also produce enzymes that break down the cellulose, starch and other materials in the wood.

Good housekeeping of a wood shake or shingle roof includes regular cleaning to remove debris and limit organism growth. A roof should be swept or leaf-blown regularly and washed at least twice per year, especially prior to the fall rains in the Pacific Northwest. Branches of overhanging trees should be removed to improve a roof’s ability to shed moisture. Accumulated plant growth retards shedding and retains moisture, favoring the fungi’s continued growth.

An experienced professional should perform any maintenance beyond basic housekeeping on a wood shake or shingle roof, including application of chemicals for fungus and moss control; removing plant growth and stains; washing and power-washing; applying water-repellant, UV-blocking and preservative treatments; and repairing and replacing damaged shingles or shakes. A service provider should use protective plastic tarps or sheets to prevent damage to surrounding vegetation and to limit overspray from chemicals. A second technician should be on the ground ready to rinse runoff and overspray with hose-pressure water, or spraying through a power-washer nozzle, as needed.


A home with slate roofing isn’t going to need a new roof for quite some time. Slate shingles can last up to 200 years and often remain in place long after the home’s original owners have moved on. This longevity makes slate a very attractive option for homeowners looking to make their properties as durable and charming as possible.

Slate roofs tend to need less maintenance than other common roofing materials, but they still require routine cleaning and inspections. Homeowners can perform some basic cleaning tasks on their own using a ladder and a brush, but it is important to contact professional cleaners for more in-depth care and repairs.

Some of the most common problems with slate roofs involve cracked tiles and faulty flashing. These issues usually lead to water leaks within the home, and they can be very expensive to repair. Performing regular roof maintenance inspections can help prevent these issues and minimize the cost of repairs.

Generally, most problems with slate roofs can be fixed with select tile replacements or a re-pointing of the flashings. However, if the problem is allowed to advance too far, it may be necessary to replace the entire roof.

If you are considering purchasing a property with a slate roof, it is important to read the warranty policies carefully. It is also a good idea to have a professional inspect the roof and determine whether it needs any attention before you move in. This will give you peace of mind that the seller is aware of any issues with the roof and will be able to provide proof of the proper maintenance and repairs that have been made.

The most important part of slate roof maintenance is the inspection process. During the inspection, homeowners should look for any signs of leaks, broken tiles, or faulty flashing. These problems should be addressed immediately, as they can lead to water damage inside the home.

Generally, it is best to have a slate roof professionally cleaned and inspected at least twice a year. Performing this maintenance can save you money on repairs and increase the lifespan of your home’s roof.


The distinctive terra-cotta hues of clay tiles add enduring beauty to any home. These sturdy roofs can withstand extreme climates, but they do require some maintenance to keep them functioning optimally. Using a ladder to reach and clean a clay tile roof can be dangerous if you don’t have extensive experience climbing up on one. Just one wrong step could shatter a fragile tile, leading to serious property damage. An experienced roofing contractor can safely inspect your clay tile roof, clean it, and repair any damaged areas.

Like any other roof, clay tile roofs collect dirt and mildew that can clog gutters and promote the growth of mold and algae. These deposits can damage the surface of the roof and cause leaks. Periodic professional roof cleanings remove these unsightly stains and restore the roof’s appearance. Never attempt to power wash a clay tile roof, since high-pressure water may crack the delicate tiles.

Clay tile roofs are durable and can last up to half a century with proper care. A professional inspection helps identify issues that can decrease their life span, such as improper installation or the presence of faulty flashing. The inspection can also determine if the roof is protected by the appropriate building codes for your area.

Besides cleaning and repair, a professional roofing company can recommend a protective sealant to discourage the accumulation of mildew, mold, and algae. This protectant is also effective against the damaging effects of sunlight and acid rain, which can discolor or damage clay roof tiles.

In addition to clay roof tiles, a quality roofing contractor will check for other areas that need attention, such as clogged gutters and debris buildup. They will also look for weakened mortar or the presence of insects, birds, and vermin. In high-humidity climates, these conditions encourage the development of mold, mildew, and lichen that can break down the surface of clay tiles.

The expert roofers at Kelly Roofing can help you keep your clay tile roof in good condition for as long as possible. A regular professional roof inspection will prevent problems from growing out of control and ensure your clay tile roof continues to protect your home for decades to come.


EPDM, or Ethylene Propylene Diene Monomer, is an inexpensive and versatile roofing material used for flat or low-sloped roofs. It is durable, resistant to moisture, and easy to repair. While these characteristics make it an attractive option for commercial roofing, proper maintenance is crucial to maximize the lifespan of your EPDM roof.

The first step in EPDM roof maintenance is regular visual inspections. This will help you identify any issues before they become serious problems, such as leaks or cracks. It’s also important to check for any debris, such as fallen leaves or branches, and water pooling on the surface of the roof. These problems can weaken the membrane and shorten its lifespan.

Regular cleaning is also essential to maintaining your EPDM rubber roof. This should be done at least four times a year, and you should use a cleaner that is specifically designed for roofs and free of petroleum distillates. You should also minimize foot traffic on the roof, as this can damage the EPDM surface.

Another common issue with EPDM is shrinkage, which occurs when the synthetic rubber loses its elasticity over time. This can cause the membrane to pull away from walls and drains, creating crevices where water, bugs, and debris can enter the building.

Professional maintenance can help you address these issues before they become major problems. A commercial roofing crew can perform an extensive inspection to evaluate the condition of your EPDM roof and make repairs as needed. They can also repair any damage caused by the original roof installer and ensure that your roof meets all local and federal regulations.
