"I initially hired Airtight Construction to replace my roof around August of 2020. Once airtight construction started working on the roof they informed me it was going to cost more. I was never given an estimate or a contract for the additional work. To date still no bill, though they ask for money continuously. While we are waiting for a roof inspection they started a kitchen remodel around sept. 2020. They removed my kitchen cabinets, replaced a few windows and did some electrical work. I began to worry about the work being done and called the city of Martinez for an inspection. They said some of the work Airtight Construction had done needed to be fixed. Things like Electrical Panel, the windows all needed to be removed because there was no sheeting. There are structural questions about how some of the beams they installed are going to be supported.. I now know no permits were pulled for the kitchen remodel,. though I asked for permits several times. I am now having to spend more money to hire new contractors to complete the job."

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.
