Look out for signs such as missing or damaged shingles, leaks or water stains on your ceiling, sagging areas, and excessive granule loss from shingles. If your roof is over 20 years old, it's also advisable to consider a replacement, even if there are no apparent issues.

The duration of a roof replacement project depends on various factors like the size of your roof, the materials used, and weather conditions. However, a typical residential roof replacement can take anywhere from a few days to a week to complete.

The best roofing material for your home depends on factors like your budget, climate, and aesthetic preferences. Common options include asphalt shingles, metal roofing, tile roofing, and cedar shakes. A professional roofer can assess your needs and recommend the most suitable material for your situation.

Some common causes are

• Leaks: Leaks can occur due to damaged or missing shingles, cracked flashing around vents or chimneys, or deteriorated sealant around roof penetrations. Prompt detection and repair of leaks are essential to prevent water damage to the interior of your home.
• Shingle Damage: Over time, shingles can become cracked, curled, or missing due to exposure to the elements, leading to potential leaks and reduced protection for your home. Regular inspections can help identify and address shingle damage before it worsens.
• Poor Installation: Improper installation of roofing materials, including shingles, flashing, and underlayment, can lead to various issues such as leaks, premature deterioration, and structural damage. It's essential to hire a reputable roofing contractor with experience in proper installation techniques.
• Gutter Issues: Clogged or damaged gutters and downspouts can cause water to overflow onto the roof, leading to water damage, mould growth, and even structural issues. Regular gutter cleaning and maintenance are crucial to ensure proper water drainage from the roof.

Yes, most reputable roofing contractors provide warranties on both the materials used and the labour performed. These warranties can vary in duration and coverage, so it's essential to discuss the details with your contractor before proceeding with any work.
