Solar panels installation for your home might interest you, and your house’s roof is the ideal place for the solar array. But is your roof up to the job? This should be your first thought.
A few points to take into account when considering whether to replace your roof before you switch to solar or not: the roof’s age, its condition, and the costs involved for repairs or replacement.
There are a few signs you might have known about already to determine the condition of your roof without even climbing up a ladder. Those signs include:
- Leaks or stains in the attic or walls
- Dark “dirty-looking” spots on the roof
- Excessive energy costs due to insufficient ventilation
Ask for a Professional inspection before installing solar panels array
For an efficiency of solar panels for your roof, you will certainly need the expertise of a professional of a solar contractor to assist you in further assessment to survey and inspect your home or office to ensure your rooftops can retain the panels on them.
The roof’s age can help the contractor determine how the roofing materials are holding up and whether they are likely to continue to hold up in the future. The material style can help pinpoint how old the roof is and they will ask you few questions about how long you’ve lived in the home or if you actually know when the roof was originally installed.
Although a typical solar array only weighs around 4 lbs. per square foot, a damaged or weak roof can end up sagging a little under the added weight over time. Sagging can mean cracks and leaks, which leads to dry rot and a host of other issues. It’s really not worth the risk!
Factor in the cost
Yes, if you really need one, a new roof is an added cost. But think about the cost involved in having the solar contractor remove the installed panels from your old roof and then reinstall them onto the new roof.
And don’t forget that when the solar panels are off, it means that you are not producing any power, so your electric bill will naturally go up until the solar panels are reinstalled and turned back on. The entire process could take a week or two depending on the varying schedules of each contractor involved, as well as weather conditions.
