Step-by-Step Guide to Installation

Preparing the Roof Surface

Clear the roof of old materials and ensure the surface is clean, dry, and flat. Repair any damaged areas to provide a solid foundation for the shingles. Before embarking on the journey of asphalt shingle roof installation, preparing the roof is a crucial step that cannot be overlooked. This preparation involves a meticulous inspection to ensure the roof deck is in pristine condition, devoid of any rot or damage. It’s essential to repair or replace any compromised sections to provide a solid foundation for the new shingles. Additionally, ensuring proper attic ventilation is paramount to prevent moisture accumulation, which can undermine the integrity of the roof over time. Installing a high-quality underlayment is another critical step, as it provides an additional layer of protection against water infiltration. By taking these preparatory steps seriously, homeowners can significantly enhance the lifespan and performance of their new asphalt shingle roof. With attention to detail and a focus on quality, preparing your roof meticulously paves the way for a successful installation, safeguarding your home against the elements for years to come.

Installing the Underlayment

Lay a water-resistant underlayment to protect the roof from moisture. This step is crucial for preventing leaks.

The installation of the underlayment is a pivotal phase in asphalt shingle roof installation, acting as the first line of defence against water ingress. This stage requires careful attention to ensure the longevity and effectiveness of your roofing system. Begin by choosing a high-quality underlayment material that complements the specific needs of your roof and climate. Synthetic underlayments are increasingly popular for their durability and moisture resistance, offering superior protection compared to traditional felt paper.

Start at the bottom edge of the roof and roll out the underlayment horizontally, ensuring it’s laid flat and smooth to avoid wrinkles or bubbles that could compromise its performance. It’s crucial to overlap each layer by at least 10cm (about 4 inches) to create a watertight barrier. Secure the underlayment using cap nails or staples, spaced evenly and according to the manufacturer’s recommendations, to prevent tearing or lifting in high winds.

Placing the Starter Shingles

Install starter shingles along the roof’s edge. These special shingles help prevent water from seeping into the edges of the roof.

Laying the Asphalt Shingles

Begin at the bottom corner of the roof and work your way up, overlapping shingles to ensure water runs off the roof without penetrating the material. Use roofing nails to secure each shingle, following the manufacturer’s guidelines for placement and number.

Installing Ridge Caps

Once all the shingles are in place, install ridge cap shingles along the roof’s peak. These provide an aesthetic finish and additional protection against leaks.

Maintenance Tips

Regular Inspections

Inspect your roof regularly, especially after severe weather, to identify and address any damage early.

Cleaning Your Roof

Keep your roof clean from debris, moss, and algae, which can retain moisture and cause damage over time.

When to Seek Professional Help

If you notice significant damage or are unsure about any aspect of your roof’s condition, it’s best to consult a professional. Regular maintenance by a roofing expert can extend the life of your roof and prevent costly repairs.


Installing an asphalt shingle roof is a significant project that requires careful planning and execution. By following these steps, homeowners can ensure their roof is installed correctly and will last for many years. Remember, while DIY can save money, don’t hesitate to contact professionals for advice or assistance if the job becomes too complex.



  1. How long do asphalt shingles last?
    Asphalt shingles typically last between 20 to 30 years, depending on the quality of the material, installation, and maintenance.
  2. Can I install asphalt shingles over an existing roof?
    While it’s possible to install asphalt shingles over an existing layer, it’s not recommended. A new installation provides an opportunity to inspect and repair the roof deck and ensures a longer-lasting roof.
  3. What’s the best time of year to install an asphalt shingle roof?
    The best time for roof installation is during warm, dry weather, typically in late spring through early fall. Extreme temperatures can affect the installation process and the materials.
  4. How can I choose the right asphalt shingles for my home?
    Consider factors such as your home’s architectural style, local climate, desired durability, and budget. Consulting with a roofing professional can also help you make an informed decision.
  5. What is the most important step in asphalt shingle installation?
    Every step is important, but proper preparation of the roof deck, including ensuring it’s clean, dry, and flat, is critical for a successful installation. This foundation affects the longevity and effectiveness of your entire roof.


  1. What maintenance is required for an asphalt shingle roof? Regular maintenance includes removing debris, such as leaves and branches, from the roof and gutters. It’s also important to look out for and address any signs of wear or damage, like cracked or missing shingles, to prevent water ingress.
  2. Are there different types of asphalt shingles? Yes, there are primarily three types of asphalt shingles: 3-tab shingles, dimensional (or architectural) shingles, and luxury shingles. Each type offers different levels of durability, aesthetic appeal, and cost, allowing homeowners to choose based on their specific needs and budget.
  3. Can asphalt shingle roofs be eco-friendly? While asphalt shingles are not the most eco-friendly roofing material due to their petroleum content and the energy-intensive manufacturing process, some manufacturers produce recycled shingles or shingles designed to reflect more sunlight, reducing energy costs and improving their environmental footprint.
  4. How does the weight of asphalt shingles impact the roof structure? Asphalt shingles are relatively lightweight compared to some other roofing materials, like clay tiles or slate. However, it’s crucial to ensure your roof structure is assessed by a professional to confirm it can support the weight of the new shingles, especially if you’re considering layering them over an existing roof.
  5. What should I do if I find algae or moss on my asphalt shingle roof? Algae and moss growth can be detrimental to your roof, holding moisture against the surface and potentially leading to damage. Special cleaning solutions are available that can safely remove algae and moss without damaging the shingles. Additionally, consider installing zinc or copper strips near the roof’s peak, which can help prevent future growth.


  1. Is it necessary to obtain a permit for installing an asphalt shingle roof? In many areas, a permit is required for significant roofing work, including installing a new roof or replacing an old one. Always check with your local building authority or council to understand the requirements and ensure compliance with local building codes.
  2. How do I know when it’s time to replace my asphalt shingle roof? Signs that your roof may need replacing include widespread curling or buckling shingles, loss of granules, visible leaks or daylight through the roof boards, and an aged appearance. If your roof is over 20 years old, it’s a good idea to have it inspected by a professional to assess its condition.
  3. How do weather conditions affect asphalt shingle roofs?
    Extreme weather conditions, including high winds, heavy rain, and severe temperature fluctuations, can significantly impact the longevity and performance of asphalt shingle roofs. It’s important to select shingles rated for your specific climate and to conduct regular inspections to identify and address any weather-related damage promptly.
  4. Can I install a skylight with my asphalt shingle roof?
    Yes, skylights can be installed in conjunction with asphalt shingle roofing. However, it’s crucial to ensure that the skylight is properly flashed and sealed to prevent leaks. Hiring a professional roofer for the installation is recommended to ensure that the integrity of the roof is maintained.
  5. How do I choose a reliable contractor for my asphalt shingle roof installation?
    Look for a licensed and insured roofing contractor with a solid reputation and experience in installing asphalt shingle roofs. Ask for references, read online reviews, and request quotes from several contractors to ensure you find a reliable professional who offers quality workmanship at a fair price.
