Sloped roofs often face common issues that can lead to significant problems if not addressed. One typical concern is rainwater ingress, especially during gale-force winds, when water can get under the tiles due to felt issues. Additionally, moss buildup can trap rainwater on deteriorated felt, resulting in ineffective repairs over the years. Regular preventive maintenance checks by skilled tradesmen are essential to accurately diagnose and remedy these issues, helping you save money in the long run.
