April Showers Bring Roof Mold

Warmer temperatures and rain can only mean one thing this time of year. It’s roof mold season. My phone rings off the hook for cleanings in April and May when moisture and humidity kick into high gear, giving mold and mildew the perfect opportunity to thrive. So what’s with the black, streaky stains popping up on everyone’s houses and what can you do to get rid of them?

Stains on the roof are generally algae, which gets carried by wind or birds from roof to roof, and may not be visible until they have enough moisture, heat, and humidity to grow and spread. Now don’t be too alarmed, algae isn’t necessarily going to ruin your roof immediately, but it does affect the curb appeal of your home and the problem could end up damaging and pulling up your shingles if not dealt with for a long period of time.
An interesting fact is that copper, zinc, and lead are toxic to algae, and many newer roof shingles contain copper granules, which act as a barrier against any mold growth. Homes with older roofs won’t benefit from this technology, but it explains why you won’t see algae where metal flashing has been installed. If you’re susceptible to algae and in the market for a new roof, be sure to inquire about this type of shingle.

So now that we know what it is, how do we get rid of it? The easiest way to rid your roof of algae is a good cleaning solution, which can be picked up at the hardware store, applied using a pump sprayer and rinsed with the garden hose. One tip is to give any plants below the roof a good drink of water beforehand so they don’t absorb the solution. If you’re not comfortable on a ladder, call a professional to help you complete this task. A clean roof isn’t worth a trip to the hospital, and a local area home improvement specialist will be able to complete the job in just a few hours.

Once the roof has been cleaned, you might want to do something to prevent the mold from coming back again. As I mentioned, copper, zinc and lead-coated sheet metal are toxic to algae, so installing a strip of flashing will help stop that nasty fungus in its tracks. Choose a strip that’s at least six inches wide, and have it installed at the roof peak to ensure that the metal molecules wash down with the rain and protect the roof from mold build up.

Protect Your Home From Future Wind Storms with These Six Tips

This week’s wild wind was not to be taken lightly. I’ve had calls from all over the area to fix roofs, repair gutters, and replace siding that was damaged. While high winds aren’t very common, they can cause major headaches for homeowners, especially those who have to go through the process of making an insurance claim. With that being said, here are my six tips for “weathering the storm” that inevitably comes with unanticipated damage to your home.

Check your policy now

Every insurance policy is unique and it’s really important to review your coverage annually to make sure you’re up to date with the inclusions and exclusions. Most homeowner's policies cover damage due to wind but other storm-related issues such as flooding are usually not part of the deal. The State of Connecticut Insurance Department has a basic homeowner’s storm damage FAQ on their website, but because all policies and insurers are different, it’s worth talking to your agent.

Be very careful

Damage can’t always be seen, so it’s important to exercise extreme caution. Inspect the powerlines around your home as well as the trees. Even if nothing is down now, a broken limb could fall later, so it’s better to be diligent. Also, be sure to watch for leaks in the days and weeks after bad weather. High winds often rip off shingles, leaving roofs exposed to rain and snow.

Make use of your camera

The most common types of storm-related damage are to roofs, windows, siding, and windows. As you inspect your home, take photos or everything and don’t move anything unless it's necessary. Video is also a great way to document any potential damage. The more evidence that you have, the better off you’ll be when you go to make an insurance claim.

Call your insurance company

Once you’ve assessed any potential damage, you can get in touch with your insurance provider. Do this as soon as possible and be ready with all the documentation that you’ve collected. Your insurer will be able to assess the damage to your home and help you understand what's covered by your policy. They’ll also connect you to a claims agent if required.

Make repairs

After you’ve reported any damage, it’s time to clean up. Leaving exposed areas uncovered and not fixing leaks will create much bigger problems, so be sure to clear and patch any problem spots. Do not ever try to touch downed power lines or electrical equipment - report those to your electricity provider or even your town’s fire department.

Hire a good, local contractor

Believe it or not, there are some hacks out there who chase storm damage, taking advantage of homeowners who need a fast fix. Don’t fall for these traps - look for someone local and reputable who has a good track record and is fully licensed and insured. The Better Business Bureau is a great place to get started.

Waterproof Your Chimney Now to Avoid Costly Repairs Later

You may have never thought about exterior chimney maintenance unless you’ve had a problem, but because chimneys come up above the roof line, they are more susceptible to harsh weather than any other part of your home. That’s why spending a little time and money to waterproof and protect the area can save you thousands of dollars and plenty of potential headaches down the road.

If you plan on waterproofing your chimney, the first thing you’ll have to do is measure the surface area. Take care to measure all sides and add the measurements together to find the total surface area. This will help you to determine how much material you will need.

Now, it’s time to clean. Your chimney will most certainly have mold, dirt, rust, and stains on it, and you’ll want to remove them before starting the waterproofing process. I like Chimney RX Safer Brick and Masonry Cleaner which you can use instead of muriatic acid for the same cleaning power without the harsh fumes or risk of burns. Applying the solution is easy: just use one part cleaner with four parts water and apply to the area with a pump sprayer. You can then either scrub the surface or use a power washer to remove the debris. Let everything dry for at least 24 hours before moving on to the next step.

Next, you can start to prepare the area for any potential repair work. You don't want to damage your roof and shingles when waterproofing your chimney, so use a canvas drop cloth to cover the area as plastic can get very slippery. Make sure to cover over any windows or skylights that are in reach as well. Once waterproofing overspray has been applied, it will be incredibly difficult to remove.

If you have minor cracks in the chimney, now is the time to fill them. Chimney RX makes a Masonry Crack and Joint Sealant that works really well on small cracks up to one-eighth of an inch. It simply paints on and then dries a milky white color. However, if you have larger cracks or if you need any part of the chimney rebuilt or tuckpointed, I highly suggest calling a professional to manage the repair.

Once minor work has been completed, you’re ready to apply the waterproofing agent. Again, ChimneyRX makes a great product for the job. No matter what you use, be careful. Most people don’t realize that there is a difference between water repellent and sealant. A sealant will form a hard surface, trapping water inside and making the area susceptible to leaks, whereas a repellent will still enable the porous bricks to breathe and move the way they are supposed to.

Applying the sealant is as easy as the cleaning step - all you’ll need is a pump sprayer with a fan nozzle. The product that you use will give instructions for the amount that you’ll need, so just go by your surface area and the directions provided. I always suggest starting from the base and working your way up, applying heavy coats using a side to side spraying motion. Unlike painting, it’s a good idea to apply a “flood coat” first and then top it up with a second coat within just a few minutes to even it out. For areas that feel oversaturated, have a soft bristle brush handy. Also, be sure you’re working in good weather - while waterproofing products do dry quickly, you’ll want to give them a good six hours in the sun to fully set before a bout of bad weather.

Finally, just like any job on a roof, please make sure you’re comfortable with heights and working from a ladder before you tackle this project. The last thing we want us a trip to the emergency room from a nasty fall. When in doubt, always hire a pro to tackle the job.
