Important — Please Read
This figure is a possible estimate only based on the square footage you provided. It is not a formal quote or contract price.
- The actual number of squares needed for your roof replacement or new installation can only be determined through a proper on-site roof measurement and assessment.
- You may be eligible for discounts — including insurance claim assistance, referral credits ($200–$500), seasonal promotions, and financing options through Foundation Finance — which can only be confirmed after an inspection.
- Final pricing may vary based on roof complexity, pitch, existing layers, decking condition, and materials selected, among other factors found during inspection.
To get an accurate estimate, Janja Group LLC offers a FREE roof inspection at absolutely no cost and no obligation. Our licensed inspector will measure your exact roof, assess all conditions, and provide you with a precise itemized quote — along with every discount you may qualify for.
