When to Replace Your Roof
Sometimes it makes more sense to replace an old roof than to repair it.
Knowing when it's time for a new roof can save you a lot of stress (and money). Some common signs that it might be time to replace your roof include:
​
-
Roof is 20+ years old (timeline may differ depending on building material)
-
Curling, cracked, or missing shingles
-
Frequent leaks of water damage
-
Moss or algae buildup
-
Sagging roof structure
-
Energy bills increasing due to poor insulation
​
We offer free roof inspections in Nazareth and surrounding areas to help you decide whether a roof replacement is needed.
Types of Roofs We Install
We work with all major roofing materials and styles to match your home's look, budget, and needs. Not sure which type of roof is right for your house? We’ll walk you through the pros and cons and help you make the best decision.
