Concerning Spray-on Asphalt Roof Coatings

 
Picture
There are companies that sell spray on coatings for asphalt shingle roofs claiming overriding benefits to the homeowner, such as: longer roof life, energy-use reduction, or remediation of small roof leaks. There is little to no available documentation showing the true extent of these benefits, with some having an expected life span of only a few years. While some coatings can temporarily restore flexibility and improve energy efficiency, they cannot fully repair aging shingles and may lead to trapped moisture and premature failure. They are, at best, a short-term life extension on a roof that is in decent condition. They are not a good solution for heavily worn, curling, or leaking shingles.

​Be it acrylic, silicone, polyurethane, soy, plant, emulsion, or elastomeric -based, the Asphalt Roofing Manufacturers Association (ARMA) does not recommend the application of any type of field-applied aftermarket coating over installed asphalt shingles. Their primary concerns include:
  • Warranty Issues—most shingle manufacturers explicitly state that field-applied coatings will void the warranty.
  • Moisture Retention—coatings can trap moisture in the shingles, leading to premature aging, mold, or rot.
  • Adhesion Problems—asphalt shingles have a protective granule layer. Coatings may not adhere properly and can peel, crack, or flake over time.
  • Thermal Expansion Issues – Shingles are designed to expand and contract with temperature changes. Many coatings lack flexibility, leading to cracking or separation.
  • Fire and Energy Rating Alterations – Applying an unapproved coating could reduce the fire resistance and/or energy rating of the shingles.
Note: If you live in California and want to proceed, please be advised that while California's building codes do not explicitly address field-applied roof coatings on asphalt shingles, any such application must adhere to manufacturer guidelines, maintain fire-resistance classifications, and comply with Title 24 energy efficiency standards. It is advisable to consult with local building authorities or a licensed roofing professional before applying any roof coating to ensure full compliance with all applicable regulations.
The ARMA states that asphalt shingles are designed to perform as manufactured. Instead of spending hundreds or thousands of dollars on a coating with limited short-term benefits, they recommend proper maintenance and ventilation as better ways to extend a roof’s lifespan:
  • If your roof is nearing the end of its life, a partial repair or full replacement may be a better long-term investment.
  • Improving attic ventilation and routine maintenance (cleaning debris, sealing minor leaks) can naturally extend shingle life.
  • If energy efficiency is the goal, proper attic insulation could be a smarter investment.
    ​
Spray-on roof coatings are marketed as a cost-effective way to extend the life of asphalt shingles, but they come with some significant drawbacks. While some coatings claim to restore flexibility and improve energy efficiency, they can also trap moisture, void manufacturer warranties, and alter fire ratings. Industry experts, including the ARMA, generally advise against their use. Although coatings could provide a short-term solution, they are often not a cost-effective alternative to proper roof maintenance or replacement.

Protecting Your Home’s Foundation: The Importance of Proper Grading and Drainage

Water is one of the most destructive forces a home can face, particularly when it comes to its foundation. Poor drainage can lead to soil erosion, foundation cracks, basement flooding, and even structural instability. Fortunately, by taking proactive steps such as grading the landscape correctly, maintaining gutters and downspouts, and installing proper drainage solutions, homeowners can protect their investment and avoid costly repairs.

Grading Around the House
The slope of the ground around your home—also known as grading—is a crucial factor in directing water away from the foundation. Ideally, the soil should slope away from the house at a minimum of 6 inches over the first 10 feet. If the ground is flat or slopes toward the foundation, water can accumulate and seep into basements or crawl spaces, leading to moisture issues and potential damage.

If your yard is not properly graded, you may need to add soil around the foundation to create a proper slope. This should be done using compacted fill dirt rather than mulch or loose soil, which can wash away easily. In cases where regrading is not feasible, alternative drainage solutions such as swales or French drains may be necessary.

Gutters and Downspouts: First Line of Defense
Gutters and downspouts play a crucial role in directing rainwater away from the foundation. When they are clogged, damaged, or improperly installed, water can overflow and pool around the home, leading to moisture issues and potential structural damage.
  • Clean gutters at least twice a year to remove leaves and debris.
  • Check for leaks, sagging, or improper installation.
  • Ensure gutters are properly pitched so water flows toward the downspouts.
Downspouts should discharge water at least 5 feet away from the foundation. If they are too short, water can pool near the base of the house. Adding downspout extensions or splash blocks can help direct runoff away effectively.

Drainage Solutions to Prevent Water Damage
Even with proper grading and gutter maintenance, some properties may still experience drainage issues due to soil type, landscaping, or other factors. In such cases, additional drainage solutions may be required.
  • Swales—A swale is a shallow, sloped channel designed to guide excess water away from the home. It can be lined with grass, gravel, or stone to slow down water flow and prevent erosion.
  • French Drains—A French drain consists of a perforated pipe buried in a trench filled with gravel. It collects and redirects water away from the home, making it an effective solution for properties with persistent drainage problems.
  • Sump Pumps and Drain Tiles—For homes with basements or crawl spaces prone to water intrusion, installing a sump pump system or exterior drain tiles can provide extra protection by actively removing water from around the foundation.
​
Conclusion
Protecting your home’s foundation from water damage starts with proper grading, gutter maintenance, and effective drainage solutions. Whether it is regrading the soil, extending downspouts, installing swales, or adding a French drain, these measures help keep your foundation dry and stable. By taking proactive steps now, homeowners can avoid costly repairs and ensure their homes remain structurally sound for years to come.

Expected Lifespans of  Popular Roof Coverings

 
Picture
Your home's roof is one of its most critical components, protecting you and your belongings from the elements. The choice of roofing material can significantly impact the longevity and durability of your roof. In this article, we will explore the expected lifespans of popular roof coverings, helping you to make informed decisions when it's time for a replacement or a new installation.

Asphalt Shingles:
Asphalt shingles are the most common roofing material in the United States, known for their affordability and versatility. The lifespan of asphalt shingles can vary depending on their quality and type:
  • 3-Tab Shingles: These budget-friendly shingles typically last around 15 to 20 years.
  • Architectural Shingles: These premium shingles can last 25 to 30 years, or more, with proper maintenance.

Wood Shingles and Shakes:
Wood shingles and shakes are appreciated for their natural beauty and charm. However, their lifespan is influenced by the type of wood and maintenance:
  • Cedar Shingles: Cedar can last 20 to 30 years, but regular maintenance, like staining or treating, can extend their life.
  • Redwood Shakes: Redwood is naturally resistant to decay and can last up to 30 years or more.
Note: Fire-retardant chemicals and coatings can be applied to wood shakes or shingles to reduce their flammability. These chemicals work by slowing down the combustion process and preventing the wood from igniting easily. Some common fire-retardant chemicals used for wood include ammonium sulfate, ammonium phosphate, and borate-based compounds.

Metal Roofing:
Metal roofs are known for their longevity and durability. They can last anywhere from 40 to 70 years, or more, depending on the type of metal used, such as steel, aluminum, or copper.  Please note that the metal roof fasteners and coatings often do not have the same durability as the roofing material itself and it may be necessary to replace fasteners and repaint / recoat surfaces to achieve maximum life of the roof.
 
Clay and Concrete Tiles:
Clay and concrete tiles are popular for their aesthetic appeal and durability:
  • Clay Tiles: Clay tiles can last 50 to 100 years or more, making them a long-term investment. Since clay tiles are irregular in shape and not water-tight, attention must be given to a quality underlayment to achieve maximum life of the roof.
  • Concrete Tiles: Concrete tiles have a similar lifespan, ranging from 40 to 75 years, depending on maintenance. Some concrete tile systems are water-tight and require no underlayment.

Slate Roofing:
Slate is one of the most durable roofing materials available. Copper nails are recommended as fasteners because of their equal durability. Natural slate with copper nails can last a century or more, often outlasting the structure it covers.

Rolled Roofing and Single-ply Membrane:
Rolled roofing and single-ply membranes are often used for low-slope or flat roofs on residential buildings, sheds, or other structures such as mobile homes. They do not have the same longevity as roofing materials used on steeper-slope roofs. Generally, the expected lifespan of rolled roofing and single-ply roofing systems can range from 10 to 15 years. However, some higher-quality rolled roofing products, particularly those with multiple layers or reinforced materials, may last closer to the upper end of that range.

Synthetic Roofing Materials:
Some synthetic roofing materials, like synthetic slate or composite shingles, can have lifespans ranging from 25 to 50 years. The specific longevity will depend on the manufacturer and quality of the product.

Factors Affecting Roof Lifespan:
Apart from the roofing material itself, several factors can impact the expected lifespan of your roof:
  • Climate: Harsh weather conditions, such as extreme heat, cold, or heavy rainfall, can accelerate wear and tear on your roof.
  • Installation: Proper installation is crucial to ensuring your roof performs at its best. Improper installation can lead to premature failure.
  • Maintenance: Regular roof maintenance, including inspections, cleaning, and repairs, can extend its lifespan.
  • Ventilation: Proper attic ventilation helps regulate temperature and humidity, preventing moisture-related damage.
  • Roof Pitch: Steeper roofs tend to shed water and snow more efficiently, reducing the risk of leaks and damage.

Choosing the right roofing material for your home is a significant decision, as it can impact the longevity of your roof and your home's overall value. While asphalt shingles are the most common choice due to their affordability, other materials like metal, clay, and slate offer longer lifespans and may be worth considering for a more durable and long-term roofing solution.

​Remember that regular maintenance and proper installation are key to maximizing the lifespan of your roof. With the right care and attention, your roof can protect your home and family for decades to come.
