Questions about Purchasing or Researching a Roof

There are several signs that can indicate it’s time to replace your asphalt roof. Firstly, if you notice any missing, cracked, or curled shingles, it may be a sign of extensive wear and tear. Additionally, granules from shingles often accumulate in gutters when the roof is nearing the end of its life. If you’re experiencing frequent leaks or visible water damage inside your home, it suggests the protective barrier of the roof is compromised. Moreover, dark streaks or moss growth on shingles can indicate moisture issues and potential rot. Lastly, if your roof is over 15 years old and starting to show these problems, it’s likely time to consider a replacement. Regular inspections, particularly after severe weather events, can help you stay on top of necessary maintenance or replacement needs.

The cost of installing a new roof can vary significantly based on several factors, including the size of the roof, the type of materials used, and the complexity of the installation. According to remodeling.hw.net, the average cost of a roof in 2024 was $28,258, however, this range can fluctuate. High-end materials such as SBS shingles and any necessary repairs to the underlying roof structure can also influence the overall price. It’s advisable to buy from reputable contractors and ensure that all aspects of the job are covered in the estimate to avoid unexpected expenses.

Adequate attic ventilation is essential to prolong the life of your asphalt roof and enhance the overall energy efficiency of your home. The general rule of thumb for attic ventilation is to have 1 square foot of ventilation (both intake and exhaust) for every 300 square feet of attic space. This translates to balanced ventilation, which means that the amount of intake ventilation should be equal to the amount of exhaust ventilation. Intake vents are typically placed along the eaves of the roof, while exhaust vents are located near the peak. Proper attic ventilation helps in regulating temperature and moisture levels, preventing issues such as mold growth, ice dams, and excessive heat buildup. Adequate ventilation not only protects your roof from premature aging but also contributes to a more comfortable living environment within your home. Regular inspections can ensure that your ventilation system remains effective and unobstructed.

Installing new shingles over existing shingles is a practice that is often debated among roofing professionals. While it is possible and can be more cost-effective in the short term, it comes with certain considerations and limitations. Layering new shingles over old ones adds extra weight to the roof structure, which might not be designed to handle the additional load, especially if multiple layers already exist. Building codes typically only allow up to two layers of shingles before requiring a complete tear-off to ensure structural safety. Also, most shingle companies will only warranty your roof if you have a full tear-off. Another downside is that covering old shingles means that any existing issues, such as damaged or rotting underlayment, won’t be addressed, potentially leading to greater problems down the line. Before proceeding with this method, it’s crucial to consult with a roofing expert to assess the current state of the roof and ensure that it can safely support a new layer. Additionally, consider if the immediate cost-saving benefits outweigh the potential long-term risks to your home’s structure and your roof’s overall longevity.  At Lighthouse Exteriors, we only do full tear-offs.

Identifying the source of a roof leak can be challenging, but several methods can help pinpoint the problem. Begin by inspecting the attic during daylight hours. Look for any spots where sunlight penetrates through the roof; these are clear indicators of holes or cracks. Water stains, mold growth, or damp spots on the attic ceiling or walls can also signal the general area of the leak.

Next, examine the exterior of the roof. Pay close attention to common leak sources such as valleys, vents, chimneys, skylights, and flashing. Shingles should be checked for any signs of damage, such as curling, blistering, or missing pieces. If the leak is still elusive, conduct a water test. This involves spraying water on the roof section-by-section while another person remains in the attic to observe where the water seeps through.

Remember, leaks can travel along beams and rafters before dripping down, making the origination point sometimes difficult to locate. Persistent issues may require professional assistance to accurately diagnose and repair the leak, ensuring the long-term integrity of your roof.  Give us a call and we can inspect your roof and give you a free estimate.

Lastly, check for any state-specific certifications or licenses that are required in your area, as these vary by state and ensure the contractor has met local regulatory standards. Verifying these certifications ensures that the contractor is well-equipped to deliver high-quality and safe roofing services.

Understanding why roof quotes can vary significantly between contractors involves considering several key factors. Firstly, the type and quality of materials used can greatly influence the cost. Premium materials like architectural or SBS shingles tend to be more expensive than basic asphalt shingles. Secondly, labor costs can differ based on the contractor’s experience, expertise, and labor rates. Contractors with a highly skilled workforce may charge more but likely offer superior workmanship.

The complexity and size of the roof also play crucial roles. A larger or more complex roof with numerous angles, valleys, or features like skylights requires more time and effort to install, leading to higher quotes. Additionally, roof accessibility can impact costs; roofs that are difficult to access may require special equipment or additional safety measures.

Scope of work is another consideration. Some quotes might include additional services such as tearing off the existing roof, installing new underlayment, or addressing potential structural issues, while others might not. Contractors that offer comprehensive warranties or guarantees may also charge more initially, reflecting the long-term security they provide.

Lastly, local regulations and permits can affect the overall cost. In some areas, contractors must adhere to stringent building codes or obtain permits, which can add to the project’s expense. Being aware of these factors can help you better understand and evaluate the quotes you receive, ensuring you make an informed decision about your roofing project.

Storm, Weather and Insurance Questions

Hail can significantly damage shingles, compromising the integrity of your roof and potentially leading to further issues if not addressed promptly. When hailstones impact asphalt shingles, they can cause granule loss, which is essential for protecting the shingle from UV rays and weathering. This loss of granules exposes the underlying asphalt to the sun, leading to faster degradation. Additionally, hail can create cracks or fractures in the shingles, which can lead to leaks and water damage in your home. In severe cases, hailstorms can cause punctures or dents, particularly in older or already weakened shingles, resulting in immediate structural concerns. It’s crucial to inspect your roof after a hailstorm and consult a professional if you notice any signs of damage to ensure necessary repairs are made and further issues are prevented.

Dealing with storm damage can be a stressful experience, and having a roofing contractor who is willing to work with your insurance company can greatly ease that burden. At Lighthouse Exteriors, we have experience in handling insurance claims and can assist you through the process. We will work with your insurance company and are willing to provide detailed documentation of the damage, including photographs and written reports, to support your insurance claim. We are familiar with the insurance company’s procedures and requirements, streamlining communication and ensuring that all necessary paperwork is completed accurately and promptly. Collaborating with your insurance company helps ensure that the repairs are covered under your policy and minimizes out-of-pocket expenses, providing peace of mind during an already challenging time.

An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow from draining off the roof. The snow that melts backs up behind the ice dam and can leak into the home, causing damage to walls, ceilings, insulation, and other areas. Ice dams typically form when the upper part of a roof’s surface is warmer than the lower part. This warmth causes the snow on the upper part to melt and flow down until it reaches the colder, lower part and refreezes, creating a blockage. Several key factors, such as poor attic ventilation, inadequate insulation, and fluctuating temperatures, contribute to the formation of ice dams.

Preventing ice dams involves a combination of improving insulation and ensuring proper ventilation. Proper attic insulation minimizes the amount of heat rising and warming the roof’s surface. Ensuring that the attic is adequately ventilated allows cold air to circulate and keeps the roof’s surface temperature more uniform. Additionally, sealing any gaps in ceilings and around fixtures can prevent warm air from escaping into the attic. Installing roof and soffit vents to promote airflow and keeping gutters clean to facilitate drainage can also help prevent ice dams. Taking these preventative measures can significantly reduce the risk of ice dam formation and the associated potential damage to your home.

Roofing Material Questions

The primary difference between asphalt and SBS (Styrene Butadiene Styrene) shingles lies in their composition and performance. Traditional asphalt shingles are made from a base of fiberglass, which is then coated with a layer of asphalt and topped with granules that provide UV protection and aesthetic appeal. These shingles are relatively affordable, easy to install, and offer a good balance between durability and cost.

On the other hand, SBS shingles are a type of modified bitumen shingles. They incorporate a synthetic rubber called Styrene Butadiene Styrene into the asphalt, which enhances the shingles’ flexibility, impact resistance, and overall durability. This modification allows SBS shingles to withstand extreme weather conditions, such as heavy hail or high winds, better than traditional asphalt shingles. SBS shingles also tend to be more resistant to cracking in cold temperatures and can offer a longer lifespan. However, these superior properties come at a higher cost compared to standard asphalt shingles. Homeowners looking for advanced performance and longevity might consider SBS shingles as a worthwhile investment, especially in areas prone to severe weather.

Architectural shingles, also known as dimensional or laminate shingles, are a premium type of asphalt shingle designed to provide both aesthetic appeal and enhanced durability. Unlike traditional three-tab shingles, architectural shingles are composed of multiple layers of asphalt-coated fiberglass, which are fused together to create a thicker, more robust roofing material. This multi-layer construction not only increases the shingles’ resistance to wind and weather but also provides a textured, dimensional appearance that can mimic the look of natural slate or wood shakes.

These shingles come in a variety of shapes, sizes, and colors, allowing homeowners to achieve a customized, high-end look for their roofs. In addition to their visual advantages, architectural shingles generally offer a longer lifespan, with many products boasting warranties of 30 years or more. While they come at a higher cost compared to standard three-tab shingles, the investment can be worthwhile due to their superior performance and the added curb appeal they bring to a home.

Drip edge is a metal flashing that is installed along the edges of your roof to direct water away from the fascia and into the gutters. It is typically made from galvanized steel, aluminum, or copper and is an essential component for maintaining the structural integrity of your roof. The primary purpose of the drip edge is to prevent water from seeping under the roofing materials, which can lead to rot, mold, and other water-related damage.

The importance of drip edge cannot be overstated. First and foremost, it enhances the durability of your roof by providing a barrier against water infiltration. Without drip edge, water can wick behind the fascia board, causing wood rot and potential damage to the underlying structure. Additionally, it helps to protect your home from the elements by sealing the edges of the roof and reducing the risk of wind-driven rain penetrating beneath the roofing materials.

Moreover, drip edge contributes to the overall aesthetic of your roof by giving it a finished look. It also plays a crucial role in directing water into the gutters, thereby ensuring effective drainage and reducing the risk of water pooling around your home’s foundation. Installing drip edge is a relatively inexpensive way to extend the life of your roof and protect your home from water damage, making it a smart investment for any homeowner.

An ice and water barrier, also known as ice and water shield, is a self-adhering membrane used as an additional layer of protection for your roof. Installed beneath the shingles, it serves as a waterproof barrier that safeguards vulnerable areas from water infiltration. These barriers are particularly crucial in regions susceptible to ice dams and heavy rains, as they provide an extra layer of defense against leaks and water damage.

The ice and water barrier adheres directly to the roof deck, forming a watertight seal. This is especially beneficial around critical areas such as eaves, valleys, and skylights, where water is most likely to collect and potentially penetrate the roof. By preventing water from seeping into the underlying structure, the barrier helps to avert the formation of rot, mold, and mildew, which can compromise the integrity of your home’s framework.

Synthetic underlayment is a modern roofing material designed to provide superior protection under roof coverings. Unlike traditional asphalt-saturated felt paper, synthetic underlayment is made from polymers, which render it more durable, lighter, and resistant to weather elements. Its composition usually includes woven or spun bonded polypropylene or polyethylene, making it exceptionally strong and tear-resistant.

One of the key advantages of synthetic underlayment is its ability to offer excellent water resistance while allowing for breathability, which helps prevent moisture buildup and potential roof damage. Moreover, it is less prone to wrinkling and buckling compared to traditional felt, providing a more even and secure surface for the installation of shingles or other roofing materials.

Installation of synthetic underlayment is generally quicker and easier, as it is available in larger, lighter rolls and can be secured with fewer fasteners. This not only reduces labor time but also minimizes the number of potential entry points for water. Additionally, many synthetic underlayments come with anti-slip surfaces, enhancing safety for roofers working at height.

Due to its improved performance and longevity, synthetic underlayment has increasingly become the preferred choice for both residential and commercial roofing projects, making it a valuable component of a reliable roofing system. While it may come at a higher cost compared to traditional felt, the benefits of durability, weather resistance, and ease of installation often justify the investment.

When it comes to flat or low slope roofs, not all roofing systems are created equal. Due to the minimal pitch, these roofs require specialized materials and installation techniques to effectively manage water drainage and prevent leakage. Among the most popular and effective systems for flat or low slope roofs are:

  1. Modified Bitumen Roofing (MBR): This multi-layer system includes asphalt-based sheets combined with plastic or rubber modifiers. The layers are typically heat-welded together, providing excellent waterproofing and durability. Modified Bitumen is known for its ability to withstand various weather conditions and its relative ease of maintenance.
  2. Ethylene Propylene Diene Monomer (EPDM): Commonly referred to as rubber roofing, EPDM is a durable, flexible, and cost-effective synthetic material. It is highly resistant to UV radiation, ozone, and weather elements, which makes it an ideal option for flat and low slope roofs. Installation is relatively straightforward, and it requires minimal maintenance over its lifespan.
  3. Thermoplastic Olefin (TPO) and Polyvinyl Chloride (PVC) Roofing: Both TPO and PVC are single-ply roofing materials that offer excellent waterproofing and energy efficiency. These membranes are heat-welded at the seams, providing superior durability and resistance to leaks. TPO and PVC roofing systems are also highly reflective, which can help reduce energy costs by keeping the building cooler.

Each of these systems offers unique benefits and suitability depending on the specific requirements of the roof and building. Factors such as climate, budget, and the building’s architectural needs should be considered when choosing the best system for a flat or low slope roof. Consulting with a professional roofing contractor will ensure that you select the most appropriate and efficient system for your particular situation.

Roofing Installation Questions

Roof installation can be a significant undertaking, but a reputable roofing contractor will take careful measures to protect your yard throughout the process. Here are some methods used to ensure your property remains unharmed:

  1. Covering Plants and Landscaping: Contractors will often use tarps and protective coverings to shield plants, shrubs, and flower beds from falling debris. This helps prevent damage to your landscaping and keeps your yard looking tidy.
  2. Covering Windows: Depending on the roof and home, we will lean plywood or tarps across all windows to protect them from falling debris.
  3. Setting Up a Designated Work Area: Creating a designated space for materials, tools, and debris ensures that the working area is confined and organized. This limits disruption to your yard and reduces the risk of accidental damage to other parts of your property.

  5. Debris Management: An efficient debris management system, including the use of debris tarps and ground protection systems, helps in collecting and properly disposing of roof tear-offs and waste materials. Professional roofers will carry out frequent cleanups to ensure that debris does not accumulate or spread.
  6. Protecting Driveways and Walkways: Driveways and walkways can be at risk of damage from roofing activities. Protective coverings like tarps and boards are used to safeguard these areas from falling items or spills.
  7. Final Cleanup: A thorough cleanup after the installation is vital. Magnetic sweepers are employed to ensure there are no stray nails or metal fragments left in your yard. The team will also walk the property to inspect and ensure all debris and coverings have been properly cleared away.

By employing these protective measures, we demonstrate our commitment to respecting and maintaining the integrity of your yard and surrounding environment. Discussing these precautions with your contractor before the project begins can provide peace of mind and ensure a smooth installation process.

Yes, installing a roof in the winter is possible, but it comes with several challenges and considerations. Winter roofing projects can be successfully completed with careful planning and the right materials. Here are some important points to consider:

  1. Temperature and Material Handling: Certain roofing materials, like asphalt shingles, can become brittle in cold temperatures, making them harder to work with and more prone to cracking. Manufacturers often provide specific guidelines for storing and installing materials in colder weather to ensure their performance is not compromised.
  2. Safety Concerns: Winter conditions can make roofing work more hazardous. Icy surfaces, snow, and cold winds can increase the risk of slips and falls. Proper safety measures, including the use of fall protection gear and snow removal, are essential to ensure the safety of the roofing crew.
  3. Weather Delays: Inclement weather, such as heavy snowfall, high winds, and freezing rain, can cause delays in the roofing process. It’s crucial to monitor weather forecasts and plan work around favorable conditions to minimize disruptions.
  4. Adhesive and Sealant Efficiency: Some adhesives and sealants used in roofing installations require specific temperature ranges to cure properly. It is important to use products that are designed for low-temperature applications to achieve the best results.
  5. Ventilation and Moisture Control: Proper ventilation is critical in the winter to prevent ice dams and moisture buildup, which can lead to leaks and damage. Ensuring that the roofing system includes effective ventilation components can help maintain the roof’s integrity.

By addressing these challenges and incorporating appropriate strategies, we can successfully install roofs even in the colder months.  Our rule of thumb is usually to install on nice days when the temperature is above 40 degrees.

Post Roofing Installation Questions

The life expectancy of an asphalt roof typically ranges between 15 to 30 years. This variance is influenced by multiple factors, including the quality of the materials used and proper ventilation of the attic. High-quality asphalt shingles can last closer to 30 years when installed correctly. Some factors that can decrease the life of the roof.  Hail or high wind can create areas of weak or damaged shingles that will fail before the undamaged areas.  Improper ventilation will also cause excess heat in the summer and ice buildup in the winter that will both weaken and prematurely age the shingles.  Areas that collect debris or trees that touch the roof can also cause excess moisture and algae, which will also cause the shingles to fail prematurely.

To prevent algae or black streaks on your roof, there are several proactive measures you can take. Firstly, install zinc or copper strips near the roof’s peak, as rainwater will pick up small amounts of these metals and inhibit algae growth as it runs down the roof. Regularly cleaning your roof with a solution of water and mild bleach can also help remove any existing algae and prevent new growth. Additionally, trimming back tree branches that hang over your roof can reduce the amount of shade, thereby minimizing the moist and cool conditions that algae thrive in. Opting for algae-resistant shingles is another effective long-term solution, as these shingles are treated with copper granules that prevent algae and black streaks from forming. Owens Corning® StreakGuard® and Atlas with 3M Scotchgard™ are both features on the shingles we sell.  Lastly, ensuring proper roof ventilation helps to keep the roof dry and less susceptible to algae growth. Implementing these steps will help maintain the aesthetic and functional integrity of your roof over time.

Shingle manufacturer warranties are designed to provide homeowners with peace of mind by ensuring that the roofing materials used in their home are covered against defects and potential issues. Here’s an overview of how these warranties typically work:

  1. Types of Warranties: There are often two types of warranties associated with asphalt shingles: the manufacturer’s warranty and the contractor’s workmanship warranty. The manufacturer’s warranty covers defects in the roofing materials themselves, while the workmanship warranty covers the installation process.
  2. Coverage Duration: Manufacturer warranties usually last between 20 to 50 years, depending on the quality and type of shingle. Some premium shingles come with a lifetime limited warranty, which typically extends the coverage for as long as you own the house, though specifics can vary.
  3. What’s Covered: These warranties generally cover manufacturing defects that could result in issues like premature shingle cracking, granule loss, or manufacturing faults that affect performance. It’s important to read the warranty document closely to understand exactly what is covered.
  4. Exclusions and Limitations: Manufacturer warranties often have exclusions and limitations. For example, they may not cover damages caused by uncertified installers, extreme weather events, or lack of maintenance. Issues like algae growth, which can be common with asphalt shingles, might not be covered unless explicitly stated.
  5. Prorated Coverage: Most shingle warranties start with full coverage that is prorated over time. This means that as the roof ages, the amount that the manufacturer will cover decreases. After a certain period, homeowners may be required to pay a portion of the replacement costs.
  6. Transferability: Some warranties are transferable to a new homeowner, which can be an attractive feature if you plan to sell your home. However, there may be stipulations or fees involved in the transfer process.
  7. Filing a Claim: To file a claim, homeowners need to provide proof of purchase and documentation of the problem. The manufacturer might also require a certified roofing contractor to inspect the roof to verify the defect. The claim process can take time, so it’s essential to keep all relevant records handy.

By understanding how shingle manufacturer warranties work, homeowners can make informed decisions when selecting roofing materials and ensure they are taking the necessary steps to maintain their roof and keep the warranty valid.
