Maintaining an Asphalt Shingle Roof in Portland, ME

Regularly maintaining your asphalt shingle roof in Portland, ME, is crucial to ensure it lasts as long as possible. Our team at The Roof Doctors knows all about the specific challenges our climate presents. Let’s dive into some practical tips to keep your asphalt shingle roof in top shape.

Understanding Your Asphalt Shingle Roof in Portland, ME

Asphalt roofs are popular in Portland, ME, due to their durability, cost-effectiveness, and variety of styles. They typically have three main components:

  1. Base Mat: Made from organic materials or fiberglass, providing the foundational layer.
  2. Asphalt Coating: Coats the base mat to make the shingles waterproof and enhance durability.
  3. Protective Granules: Ceramic-coated mineral granules on top provide UV protection and aesthetic appeal.

These layers work together to create a practical and durable roof material that can repel water, withstand harsh weather, and come in various styles and colors.

Common Issues With Asphalt Shingle Roofs

Like any roofing material, an asphalt shingle roof in Portland, ME, faces certain issues. Here are some common problems:

  • Weather Damage: Severe weather, like hail or heavy snow, can crack or break asphalt shingles.
  • Moisture and Algae Growth: Humid summers and wet winters can promote algae and moss growth, undermining shingles over time.
  • Thermal Shock: Rapid temperature changes can cause shingles to consistently contract and expand, leading to cracks or splits.
  • Wind Damage: Strong winds can lift or rip shingles, compromising the roof’s protection.

Understanding these issues is the first step in maintaining your asphalt shingle roof in Portland, ME.

Regular Inspections

One of the best ways to maintain your Portland, ME, asphalt shingle roof is through regular inspections. Here’s what to look for during an inspection:

Visual Inspection

Start with a visual check from the ground. Look for:

  • Missing Shingles: Gaps where shingles should be.
  • Curling or Buckling Shingles: Shingles that are warped or distorted.
  • Granule Loss: Bare patches on shingles indicating granule loss.
  • Debris: Leaves, branches, or other debris on the roof.

Up-Close Inspection

If you’re comfortable and experienced getting on a ladder, an up-close inspection can help spot finer details:

  • Check Flashing: Look around chimneys, vents, and skylights. Flashing should be intact and without rust.
  • Look for Cracks: Inspect individual shingles for splits or cracks.
  • Gutter Check: Ensure gutters are not clogged and are securely attached.

Regular asphalt shingle roof inspections can catch small issues before they become big problems.

Cleaning Your Roof

Keeping your asphalt shingle roof in Portland, ME, clean is essential. Here’s how to do it safely:

Removing Debris

Use a leaf blower or roof rake to remove leaves and branches. Avoid using a pressure washer on your asphalt roof, as it can damage the shingles.

Dealing with Moss and Algae

For moss and algae, use a mixture of water and mild detergent. Apply it gently with a soft brush. There are also commercial moss and algae removers available.

Gutter Cleaning

Clean the gutters around your roof regularly to prevent water from backing up and damaging your asphalt shingle roof in Portland, ME. Make sure downspouts are clear and directing water away from the foundation.

Handling Repairs

Despite your best efforts, sometimes repairs are necessary. Here’s when to repair and when to replace your asphalt shingle roof in Portland, ME.

When to Repair

  • Localized Damage: If the roof damage is confined to a few shingles, it’s usually best to repair.
  • Small Leaks: Small leaks can often be fixed by addressing flashing or replacing a few shingles.

When to Replace

  • Age of the Roof: Consider replacing roofs older than 20 years.
  • Extensive Damage: Large compromised areas or widespread granule loss indicate the need for replacement.
  • Renovation: A full replacement ensures all parts of the home are protected and consistent.

If you’re unsure whether to replace or repair your asphalt shingle roof in Portland, ME, contact The Roof Doctors for a professional assessment.

Seasonal Maintenance Tips

Different seasons bring different challenges. Here’s how to maintain your asphalt shingle roof in Portland, ME, throughout the year.


  • Inspect for Winter Damage: Look for any damage caused by snow and ice.
  • Clean Gutters: Clear out leaves and debris accumulated over winter.
  • Trim Trees: Cut back any branches that could fall on your roof during storms.


  • Check for Moss and Algae: Address any growth early to prevent damage.
  • Ensure Proper Ventilation: Good attic ventilation helps keep your home cool and prevents shingle damage.


  • Clear Debris: Remove fallen leaves and twigs from the roof and gutters.
  • Inspect Roof Again: Check for any damage from summer storms.
  • Prepare for Winter: Ensure your roof is ready for heavy snow and ice.


  • Watch for Ice Dams: Keep an eye out for ice dams and address them promptly.
  • Remove Excess Snow: Use a roof rake to gently remove heavy snow buildups.
