The Roof Design

These things will make it more difficult for a contractor to replace your roof. They might need to use special tools to help them keep their footing or to fit the material into the right spots.
Simple gable roofs are typically the most cost-effective to replace, while hip roofs and complex designs with multiple angles increase both material and labor costs for your 800 sq ft roof replacement.
