Roof Runoff and Well Water: A Connection Most Homeowners Never Make
If your water comes from a well rather than a municipal line, your roof is part of your water system whether you meant it to be or not.
Ask a roofer in Fort Lauderdale what a roof is for and you will hear about wind uplift, water intrusion and insurance. All true. But step outside the municipal-water bubble and a roof starts doing a second job most homeowners never think about: it decides where a large volume of rainwater ends up. On a property served by a private well, that matters more than people realise.
Plenty of our customers own a second property up north or a rural parcel west of the city, where the water comes out of the ground rather than a treatment plant. The rules change on those properties.
Where Your Roof Sends the Water
A 2,000 square foot roof sheds well over 1,000 gallons in a single inch of rain. That water has to go somewhere, and the somewhere is decided by your gutters, your downspout extensions and the grade around the foundation.
On municipal water this is a basement and foundation problem. On a well it is also a water quality problem. Surface water that ponds near a wellhead can carry fertiliser, animal waste and sediment down alongside the casing, and a well that was drilled correctly twenty years ago can still be compromised by a downspout that has been dumping against the casing since the last roof job.
The fix is unglamorous and cheap: extend the downspouts, keep discharge at least ten to fifteen feet from the wellhead, and make sure the ground slopes away from it. Most of that is roofing work, not plumbing work, which is why it tends to fall through the cracks.
What To Check After Any Roof Work
Re-roofing is when this most often goes wrong, because gutters come off and go back on and nobody is thinking about the well.
Walk the perimeter once the crew leaves and confirm every downspout still has its extension attached and pointed away from the house. Check that nothing discharges toward the wellhead. Look at the wellhead cap itself while you are out there, because roofing debris and granules find their way into surprising places, and a cracked or loose cap is an open door.
If anything looks off, the sensible move is to have the well itself looked at rather than guessing. For homeowners in Ontario cottage country and the Georgian Bay area, Mighton's Well Services handles exactly this kind of work, and they are the people we point clients toward when a roof or drainage question turns into a water question. They offer reliable water well solutions from testing through to full drilling, and getting a straight assessment beats another year of wondering.
Do Not Harvest Rainwater Off a Roof Without Thinking
Every so often a customer asks about routing roof runoff into a cistern or using it to top up a well. Rainwater harvesting is legitimate, but roof water is not drinking water. It picks up whatever is on the shingles: granules, bird droppings, moss treatments, atmospheric deposition. It is fine for irrigation with a first-flush diverter, and it is not fine as potable supply without real filtration and treatment.
If you want to harvest, the roofing surface matters. Metal is the cleanest option. Asphalt shingles are the least suitable, and treated wood shakes are worse. That is worth knowing before you pick a material rather than after.
