Understanding Asphalt Shingle Roofs

Asphalt shingles are a popular roofing material in the U.S. due to their cost-effectiveness, durability, and aesthetic flexibility. They consist of a fiberglass mat coated in asphalt and topped with ceramic granules that protect against UV rays and weathering. There are three primary types: 3-tab shingles, dimensional shingles, and luxury shingles, each offering different levels of durability, aesthetic appeal, and wind resistance.

What Are Asphalt Shingle Roofs Made From?

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

These components create shingles that repel water, withstand the elements, and come in various styles and colors to suit different architectural needs.

Choosing the Right Asphalt Shingle Roofing Contractor in Portland, ME

Selecting the right contractor is crucial for both roof repairs and replacements. Look for local contractors with good reputations and the following qualifications:

  • Licenses and Insurance: Ensure the contractor is licensed and insured in Maine.
  • Experience with Asphalt Shingles: Verify they have specific experience with asphalt shingle roofs in Hollis’s climate.
  • References and Reviews: Request references and read online reviews to gauge the satisfaction of previous customers.

Choosing a qualified roofing contractor ensures your roofing project is handled professionally and effectively.
