How To Treat Mold on Siding

Here in Connecticut and most of New England, vinyl siding is a popular cladding option for many homeowners. Starting in the 1950s, it became a favorite aluminum replacement due to its low maintenance and high durability. With a wide variety of colors and textures, it continues to be a fantastic option, offering personalized style without having to worry about sanding, painting, or major maintenance. 

While vinyl siding is beneficial in so many ways, one complaint is the potential for mold growth, often on the north side of a home. To be clear, mold can grow anywhere, but the north side is the area that’s most susceptible because it gets the least amount of sun exposure. Constant shade, high vegetation, or anything that stops a house from getting regular sunlight is an invitation for mold to grow in that area, whether it’s clad in vinyl or not.

In addition to lack of sunlight, excess moisture is another mold inhibitor. The cause could be as simple as trapped rainwater that’s unable to drain properly. Another possible issue could be a faulty drain pipe or a gutter that’s dripping on the siding, causing constant dampness. Either way, a moisture problem is something you’ll want to deal with as the water will continue to feed the mold, which will then spread. 

Another reason for mold growth on siding is a build-up of dirt, which is a food source for all different types of fungus. Something as simple as a dryer vent can cause dirt and dander to stick to the siding. Tree sap is also common and can be tough to remove. Homes on high-traffic roads tend to get dirty more easily as well. Any of this debris will quite literally make a meal for spores to feast on. 

So what can you do to keep mold at bay and ensure your vinyl siding looks great for years to come? Assessing your sunlight and moisture exposure is key, but what if you don’t want to cut down a tree or you happen to live in an area where moisture is a problem? A professional will be able to inspect your siding and treat the mold using a cleaner and blocker that removes spores and keeps them from coming back. It’s important to use a specially designed cleaner that is strong enough to tackle mold but not too harsh that it will damage the house. You also want to be careful not to use any bleach-containing materials so as not to harm the vegetation surrounding your home. 

Once your house is cleaned, be sure to maintain your vinyl siding by assessing your home for moisture, treating leaks promptly, and keeping your gutters clear and free of debris. An annual inspection will help to ensure that any problems are dealt with promptly so they don’t get out of control.

How Do You Know When to Replace Your Roof?

When was the last time you took a good look at the condition of your roof? If it has been a while, now is the time to do it. Most roof problems are caused by snow, wind, rain, and ice, making spring the perfect season to assess for wear and tear. 

When you look at your roof, what do you see? Are the shingles intact? Is any part sagging or discolored? Are there dark spots on the outside or ceiling cracks and yellowing inside? These can all be signs of a deteriorating roof. But how long is a roof actually supposed to last, and is a new roof worth the investment? Here are some things to think about when it comes to roof replacement.

1. How old is your roof? Roofs generally last about 20 years, and the reason I say generally is that the life of the roof depends on how it was installed and if it has proper insulation and ventilation. If a roof is done correctly, it can often last longer than 20 years. If you don’t know, it’s worth finding out, especially if you recently purchased your house or are thinking about buying one.

2. Are your shingles curling, splitting, or falling off? This could be due to age and general wear and tear. If this is happening, your roof will be much more susceptible to leaks, which can cause major problems both inside and out. Take a look at where your downspouts deposit onto the ground. If there are lots of granules, that’s a sign of shingle deterioration.

3. Do you see moss or mold growing on your roof? This is a problem that could be fixed with a simple roof cleaning, or it could be a sign that you have rotting plywood and damaging moisture trapped under the shingles. A simple inspection will tell you if it’s a quick cosmetic fix or something more complex that needs to be repaired.

4. Are there yellowish-brown stains or cracks on the ceiling inside the house? This might be water damage coming from the attic which is a problem you don’t want to ignore. If leaks are already happening, they are only going to get worse. 

Many remodelers will do a roof inspection for free, so if you’re unsure about how your roof is holding up, consult with an expert. I always tell the homeowners how long I think their roof will last based on its current condition and the external environment. The number one reason roofs don’t make it through their warranty is because of poor ventilation and insulation, which will lead to premature roof aging and rot. If you’re dealing with a good roofer, they will explain all the options available to you, so don’t be afraid to ask questions.

Outdoor Work in Winter That's a No Go

It may seem surprising but I get a lot of calls from homeowners who want to put on a new roof or update their vinyl siding during this quieter time of the year. People often think winter is a good opportunity to make outdoor improvements since it’s past the holiday period and before the busy spring sets in. As much as I hate to disappoint, now is actually a pretty dangerous time of year to do any exterior projects. Here are seven reasons why:

1. When the weather is below 40 degrees, the composition of building materials can really change. As it gets colder, products such as shingles can get brittle and crack or split easily. Materials such as vinyl siding shrink, which can lead to misalignment or potential for leaks when they later expand as the weather warms.

2. Another big issue is shingle adherence. Shingle sealant is activated by sun and heat. If there is not enough of either, the hold won’t be as strong as it should be, which could cause problems down the road. If the weather is too cold, we are often forced to hand seal, which can add time and cost to a generally simple process.

3. Most contractors use an air nail gun for external remodeling, which works by pressure. If humidity turns to ice in the airline, it can under or overdrive the nails instead of putting them in flush. Compressors face the same potential problem. 

4. Being on a roof or ladder in winter is dangerous. Even the most seasoned professionals must take care as black ice can cause serious injury. While we take every precaution, there is a lot that can go wrong during cold conditions. It’s often not worth the risk. 

5. Winter weather is unpredictable. When it rains in the warmer months, we tarp a job thoroughly to ensure there aren’t any leaks. Snow is more difficult as it adds both moisture and weight to a job. Imagine having a roof open in February and a foot of snow falls from the sky?

6. A cold weather installation could void your warranty. Many products specify a proper installation environment, which is usually above 40 degrees. 

7. Winter jobs almost always take longer as roofers need to take extra precautions and more frequent breaks while working in cold conditions. The last thing you want is someone on a roof who can’t feel their toes. There is also less daylight, which will add time to an installation.

Sometimes, a winter repair or replacement is inevitable and leaving the job until spring might make things worse. If this is the case for you, be sure that you’re working with an experienced contractor who has a solid track record in winter conditions and discuss all the precautions and extra steps that will be taken to ensure the job is done correctly. The last thing you want is someone getting injured or a situation where corners have to be cut to accommodate less-than-fair conditions. In the end, is it really worth it?
