What affects the price

Replacing your roof involves several variables that shift your final bill. The total square footage of your property is the biggest factor, followed closely by the pitch or steepness of your roof, which dictates how safely crews can work. You will also need to choose your materials—architectural shingles, metal, or tile each carry different price points. We also have to account for the removal and disposal of your current roof, plus the condition of the underlying wood decking that might need repairs once the old shingles are off. Exact pricing confirmed free on the call.

About this service

Roof sealant is a specialized coating used to bridge small gaps and waterproof vulnerable areas like flashing, vents, and joints. It creates a seamless barrier that stops water from seeping into your home's structure. You typically need this when you notice minor leaks or when your roof's existing seals start to dry out or crack due to sun exposure. Regular maintenance, including checking these seals, can prevent much larger, more expensive problems from developing inside your walls or ceilings.
