Frequently Asked Questions

Cedar roofs can last 25 to 40 years with proper maintenance, especially in Maine's humid coastal climate. Regular cleaning and treatment help prevent moisture damage and extend lifespan. At D&S Roofing and Siding, we provide specialized cedar maintenance to maximize durability and preserve natural beauty in Lamoine and surrounding coastal areas.

Six-inch gutters handle approximately 50% more water volume than 5-inch gutters, making them ideal for larger roofs or areas with heavy rainfall. Five-inch gutters work well for standard residential homes. At D&S Roofing and Siding, we measure your roofline and assess local weather patterns to recommend the right size for your property.

Most asphalt shingle roofs need replacement after 20 to 30 years, or sooner if you notice curling, missing granules, or multiple leaks. Severe storm damage can also warrant earlier replacement. Regular inspections help catch issues before they lead to interior water damage or structural problems.

Yes, metal roofs excel in coastal climates because they resist salt air corrosion, shed snow efficiently, and withstand high winds common along the Maine coast. They're also fireproof and energy-efficient. At D&S Roofing and Siding, we install metal roofing designed to handle Lamoine's harsh winter storms and humid summers.

Most leaks stem from damaged or improperly installed flashing around chimneys, vents, and valleys, followed by worn or missing shingles. Ice dams and clogged gutters also force water under roofing materials. Addressing flashing and maintaining clean gutters prevents the majority of leak issues in Maine homes.

Rubber membrane roofing, typically EPDM, is applied in large sheets that are sealed at seams to create a watertight barrier on flat or low-slope roofs. It's flexible, weather-resistant, and ideal for commercial buildings. At D&S Roofing and Siding, we install rubber roofing for both residential and commercial flat roof applications.

Seamless gutters eliminate joints where leaks typically occur, reducing maintenance and water damage risks. They're custom-fabricated on-site to fit your exact roofline measurements. This design also improves curb appeal and ensures consistent water flow away from your foundation.

Yes, gutter guards block leaves, pine needles, and debris from entering gutters, significantly reducing the frequency of cleanings. They ensure consistent water flow and prevent clogs that can cause overflow and foundation damage. At D&S Roofing and Siding, we install guards that work well with Maine's heavy leaf fall and winter conditions.

Neglecting regular maintenance is the most common error. Cedar requires periodic cleaning and treatment to prevent moss, algae, and rot in humid climates like coastal Maine. Without care, cedar deteriorates faster and loses its natural weather resistance and beauty.

Storm damage should be assessed and repaired as soon as possible to prevent water intrusion, mold growth, and structural issues. Temporary tarping can protect your home until permanent repairs are made. At D&S Roofing and Siding, we offer emergency services and work directly with insurance companies to expedite claims.

GAF and Owens Corning offer extended manufacturer warranties on materials, often ranging from 25 years to lifetime coverage depending on the product line.
