How to Deal With Water Stains On Your Roof

If there is anything any homeowner dreads, it is discovering damage in any part of your home. A conscious homeowner knows turning the other eye when they notice that something isn’t right isn’t the right way to go since it could exacerbate the problem and cause even more problems. A water stain is one of the most common tells tale signs of trouble up there on the roof. Like other minor home faults, it isn’t something to be ignored as it could lead to bigger structural and electrical damage. 

So what do you do when you notice a stain on the roof? Here are some important tips to help you deal with it: 

Find out the source of the stain

One of the most important questions to ask when you find a water stain is “how did it get there?” Usually, your answer is between one of three options.

  • Damaged roof shingles or weakened seals right above the stain 
  • Faulty plumbing which allowed the water to seep through the ceiling then evaporated leaving a discolored surface of mineral deposit. 
  • Growing organisms such as moss and algae on your roof ( this is usually in form of a green discoloration)

Finding out the source of the stain will help you in deciding your next course of action to take care of the damage. 

Repair immediately

Once you have identified the cause of the damage, the next step will be to find a professional to help you repair it. You have the option of either employing plumbing or HVAC professionals or a roofing technician depending on the type of damage you are dealing with. In the first place if you are unable to identify the cause of the damage yourself, inviting a technician to access the cause and extent of the damage is a wise decision and once that has been ascertained, getting one to have it fixed immediately is the best course of action.

Cover up the stain after the repair is done

It will be irresponsible to simply cover up a water stain without solving the underlying problem first. Get the assurance from a qualified professional that the damage causing the leak has been fixed before proceeding to clean up and cover up the stain. Here are some tips to help you do this properly. 

  • Make a mild homemade bleach cleaner using a 3 to 1 ratio of water to bleach. This helps to fade off the water spot and get rid of grease, dust, and mildew.
  • Use a heavy-duty sponge to wipe down the affected part of your roof with the bleach solution. Ensure that you wear gloves and other protective gear to protect yourself. Also, cover up the floor beneath the spot with an old sheet or drop cloth. 
  • Once this is done, Rinse off the area with some water then wipe clean with a dry cloth.
  • Paint the affected area. It is recommended that you use an old based stain and mold resistant primer first before you paint it with an oil or latex-based paint. Also, cover up the areas you don’t want the pain to get to before you start painting. 


When dealing with a stained roof, time is of the essence. Delaying will further increase the extent of damage and cost you more in the long run.
