"I would not hesitate to recommend - responsive, great communication, reasonable pricing. We had a disastrous roof flooding experience from a flat roofed dormer and needed it fixed quickly. As Roberto worked on the dormers he found significant water damage below the shingles, documenting it with photos for us. Although it cost more than the original estimate to replace the flat plywood sheaths and wood fascia, it was still reasonable and the work done was thorough and looks great. "

Clear your gutters after heavy storms or at least twice a year. If pines surround your home, bump that to every four months. Sweep loose debris off the roof whenever you see it, and schedule a professional roof and gutter cleaning when dirt starts to build up. Flat roofs trap leaves and standing water quickly, so staying ahead of clogs helps prevent leaks.
A well-maintained flat roof can last up to 25 years. Regular inspections, thorough cleaning of drainage systems, and prompt debris removal help ensure that your flat roof remains durable and performs reliably throughout its lifespan. Maintaining tight seals and applying appropriate protective coatings further secures the roof’s integrity over time, making these essential practices vital for long-term performance.
Flat roofs offer significant advantages and present certain challenges. They deliver economic benefits through reduced material and labor costs, and they enable creative outdoor living configurations. However, flat roofs also exhibit disadvantages such as a tendency for water pooling, diminished attic space, vulnerability in snowy conditions, and an elevated risk of leaks if seals are compromised. Maintaining the roof with professional inspections and precise upkeep helps overcome these challenges.
Flat roof replacement is covered by homeowner’s insurance only when damage results from a specific event, such as a storm or accident. Your policy covers the replacement if the injury is caused by a qualifying incident rather than normal deterioration or maintenance lapses. Review your policy carefully and confirm with your insurer to accurately determine your coverage.
