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

Proper insulation sits beneath your roofing material to act as a thermal barrier. It keeps your conditioned air inside during the summer and prevents heat loss in the winter, which can help stabilize your energy bills. If your home feels drafty or your HVAC system is working overtime, your insulation might be insufficient or damaged. We assess your attic and roof deck to ensure the right amount of material is installed to keep your living space comfortable year-round.
