The repair-versus-replace decision depends on roof age, extent of damage, and cost considerations. If your roof is approaching its expected lifespan (20-25 years for standard shingles) and showing multiple issues, replacement often provides better value than ongoing repairs. Similarly, if damage affects more than 30% of your roof or extends to the decking, complete replacement typically offers more reliable protection and better long-term value.
Our difference lies in our specialized expertise, quality materials, and commitment to transparency. Unlike general contractors who occasionally handle roofing, we focus exclusively on roofing and exterior systems, maintaining manufacturer certifications that allow us to offer enhanced warranty options.
