Frida in Uppsala has been dealing with a persistent moss problem on the roof of her summer house. The roof is made of roofing felt (takpapp), and she is worried about using the wrong products that might discolor it or damage it in some way. Frida is specifically considering using iron sulphate but is a bit hesitant due to potential issues. She’s also heard about products like Bensaltensid, Påväxtstopp, and Fulstopp, but doesn’t know if they would be effective or safe. Frida wants to know the best way to tackle the moss without causing any harm to the roof. Could you guide Frida on this issue? Thanks, Frida, Uppsala.
Moss is a common nuisance on roofing felt (or “takpapp” as they call it in Sweden), and you’re definitely not alone in dealing with it, Frida. Sometimes it takes a bit of understanding and the right approach to tackle the problem efficiently without causing further damage to your roof.
Understanding Moss on Roofs
Moss can not only be unsightly, but it can also shorten the lifespan of your roof. This is due to the way it retains moisture, potentially leading to wood rot or even structural issues if the water manages to sneak into your roof’s underlayers. Understanding why moss likes your roof is the first step in tackling it.
Why Does Moss Grow on Roofs?
Moss thrives in damp, shaded environments. If your home is surrounded by trees or situated in an area that doesn’t receive much sunlight, this could create prime growing conditions. Roofing felt tends to keep moisture longer than other roofing materials, which can further compound the problem.
Why Steer Clear of Iron Sulphate?
While iron sulphate is often used in gardens to help with moss, it’s not ideal for roofs, and here’s why:

Effective Alternatives to Iron Sulphate
Luckily, there are some excellent alternatives that are both effective at dealing with moss and safer for your roof:
Bensaltensid
A non-toxic solution that is particularly valued for its low environmental impact. You might appreciate that it neither stains nor corrodes, which keeps your roof looking fresh and in good condition after application.
Påväxtstopp
Ideal for those looking for a long-term solution. It acts as a preventive measure, creating an inhospitable environment for new moss spores. Think of it less as a cure and more as a vaccine for your roof.
Fulstopp
This is another great option. While not a pesticide, it works pretty well in eliminating existing growth while also providing some long-term protection. One application can last for several years, depending on environmental conditions.
Application Tips
Applying any moss removal product effectively requires attention to detail and safety:
- Timing is Key: The best time to apply these treatments is during dry, cool days so that they have enough time to soak in and take effect.
- Protection Gear: Always wear gloves and eye protection, as these chemicals, while generally safe, can still irritate skin and eyes.
- Follow Instructions: Each product comes with specific instructions regarding how to properly apply it. Adhering to these will ensure maximum effectiveness.
Preventive Measures
Once you have dealt with the current moss problem, you’ll want to prevent it from coming back:
- Regular Maintenance: Keep your roof free of debris like leaves and branches, which trap moisture.
- Sunlight: Trim back nearby trees to let more sunlight in, as moss hates sunny spots.
- Regular Inspections: Check your roof at least once a year to catch any budding moss growth early.
“An ounce of prevention is worth a pound of cure.”
While maintaining your roof can feel like a chore, simple frequent checks are far less demanding than recovering from extensive damage.
