When you do the roof replacement look for products with the longest possible warranty at least a 25 year lifespan and more if you can afford it.
Savings for doing solar at the same time as roof.
The deciding factor will primarily be the cost of electricity which varies significantly depending on where you live.
So in the past few months several people ended up calling in a roofer while we were together analyzing their solar proposals.
The graph below shows the savings for the same customer over 25 years.
When you install solar panels on your roof you are essentially turning your home into its own mini power plant.
I would also go further and say that since you cannot do 50 of your roof if you need to do your roof in order to support solar then the entire cost of the roof is eligible for the tax credit.
Even though rooftop panels extend the life of a roof it s better to begin with a roof that s newish or in good condition.
As a result when you pair solar with a roof replacement the panels actually extend the lifetime of the portion of the roof that they cover.
The other benefit of pairing solar and a roof replacement together is that if you re installing on a new roof it s unlikely you ll need to re roof during the lifetime of the system.
The amount of money you can save with solar depends upon how much electricity you consume the size of your solar energy system if you choose to buy or lease your system and how much power it is able to generate given the direction your roof faces and how much sunlight hits it.

You generate renewable energy reducing or eliminating your electricity costs altogether.
Wood shake roofs which are more popular in the northeast have about a 30 year lifespan while cement shingles tend to retire around 20 years.
