Does Spray Foam Damage Roof Shingles?

Home Maintenance Tips

Has anyone ever told you that spray foam insulation will damage your roof shingles and void your warranty? Guess what? They are wrong!

Founded in 2007, The Green Cocoon has more than 14 years of experience; insulating attics. As a result, we have heard many stories about shingles. But, the biggest fear is that your roof shingles will be damaged by spray foam insulation. Consequently, we are helping alleviate homeowners’ fears by showing them the benefits of having spray foam insulation.

Is Spray Foam Bad for Shingles?

One of the biggest fears people have is that spray foam will make shingles curl because they overheat. This misconception came about when people believed insulation was a heat source and were concerned about having a “hot roof.” In actuality spray foam is a barrier between two areas of different temperatures, for example, your attic space compared to your snowy roof.

If you don’t know the term “hot roof,” I’m sure you’ve heard of an unvented attic. If your roof deck has been insulated, that means your attic space is now part of your home’s conditioned space. This method of insulating the attic can actually be good for your roof because it can help prevent ice dams.

The Florida Solar Energy Center did a study a few years ago during the peak summer months in Florida—a state that gets much hotter than New England—measuring the temperatures of roof shingles above an attic with a radiant barrier. Depending on the color of the shingles, the study found the shingles peak temperatures were between 2- and 5-degrees Fahrenheit higher than the temperature of shingles in the same conditions without a radiant barrier.

What this study means is that you can insulate the roof deck of your home with foam insulation without any adverse effects to your shingles. Foam insulation creates thermal resistance, which is keeping the hot air out during the summer and the cool air inside.

Insulating Your Attic with Spray Foam

Now that we’ve shown you the research that your shingles won’t curl or get ruined with spray foam insulation, you might be curious about the benefits of foam insulation in your attic.

10 Home Maintenance Tips for Spring

Home Maintenance Tips

Now is the perfect time to get your home ready for spring using these 10 home maintenance tips. After a long, dreary winter, seeing the snow melt and feeling the warmer temps is a breath of fresh air. Getting your home ready for spring is more than cleaning.

Examine Roof Shingles

Examine roof shingles to see if any were lost or damaged during the winter. If your home has an older roof covering, you may want to start a budget for replacement. The summer sun can really damage roof shingles. Shingles that are cracked, buckled, or loose or are missing granules need to be replaced. Flashing around plumbing vents, skylights, and chimneys need to be checked and repaired by a qualified roofer.

Seal Air Leaks

Pay particular attention to windows and doors. If you spot cracks or gaps, caulking or weatherstripping should fix the problem; both are simple, DIY projects. Weatherstripping windows, for example, requires only measuring tape, a utility knife, and self-adhesive tape.

Insulate the Attic

Adding insulation before warmer weather arrives will prevent that from happening. Another benefit of insulating your attic now: It will help reduce heat loss during the cold winter days ahead.

Check the Gutters

Check for loose or leaky gutters. Improper drainage can lead to water in the basement or crawl space. Make sure downspouts drain away from the foundation and are clear and free of debris.

Check Outside Faucets

Check outside hose faucets for freeze damage. Turn the water on and place your thumb or finger over the opening. If you can stop the flow of water, it is likely the pipe inside the home is damaged and will need to be replaced. While you’re at it, check the garden hose for dry rot.

Service the AC Unit

Have a qualified heating and cooling contractor clean and service the outside unit of the air conditioning system. Clean coils operate more efficiently, and an annual service call will keep the system working at peak performance levels. Change interior filters on a regular basis.

Check the Foundation

Check foundation walls, floors, concrete, and masonry for cracking, heaving, or deterioration. If a significant number of bricks are losing their mortar, call a foundation professional. If you can slide a nickel into a crack in your concrete floor, slab, or foundation, call a foundation repair professional near you immediately.

Siding

Clean siding with a pressure washer to keep mold from growing. Check all wood surfaces for weathering and paint failure. If wood is showing through, sand the immediate area and apply a primer coat before painting. If paint is peeling, scrape loose paint and sand smooth before painting.

Replace Filters

Replace all filters including water, range hood, and air vent filters. You should replace these filters every 3-6 months depending on the type of filter you have.

Clean Out the Dryer Vent

Sure, you diligently clean out the lint trap every time you empty the dryer, but when was the last time you cleaned out the entire dryer vent? This easy task will not only improve the efficiency of your dryer, but it can also help prevent fires. (According to the U.S. Fire Administration, clothes dryers cause around 2,900 home fires each year.) 

In short, these 10 home maintenance tips for spring are just a few we recommend. There are many more available at energy.gov.

Monitor the Health of Your Roof During the Winter

Home Maintenance Tips

Many cities across the country were hit with a major winter storm last week, and for some, it was the first big one of the season. One area of the house that gets hit the hardest during a winter storm is the roof. Make sure to monitor the health of your roof during the winter to make sure it is strong enough to take the brunt of bad weather. If the snow isn’t melting quickly, it means that heat from your home isn’t escaping through your attic floors and then transferring from your roof to the exteriors. That means your roof is doing its job!

Bare spots and icicles mean heat is escaping

If your roof gets a decent amount of snow on it, make sure it’s not melting in specific spots. That means there’s heat loss likely due to poor insulation and/or ventilation in the attic. If that is the case, give us a call once the snow melts.

After a snowfall, every homeowner should take a look at their roof and check for hot spots—areas on the roof where the snow has melted. It’s normal for some melting around venting and fireplace exhausts, but you shouldn’t see any bare patches on your roof. A snow-covered roof means your insulation is doing its job.[1] If not, it’s time for a new insulation package!

Also, keep an eye out for icicles—another sign of heat loss. If your roof is warm enough to melt the snow but it’s cold enough outside for snow to refreeze, your roof is losing heat. That’s not healthy for your energy bills or the environment.

Remove some snow if it gets too deep

What about the weight of snow? If there’s ice too, that can be a heavy load. Add the weight of two layers of shingles and that’s one roof no one would want over their head. Generally, most roofs max out at about 20 pounds of snow per square foot, which translates to around two feet of wet snow or up to four feet of light, fluffy snow.[2]

Once you start hitting those levels, you may want to think about removing the snow. Otherwise, it could potentially cause your roof to cave in, which is a terrible experience in any weather, but particularly during subzero temperatures. Still, you can’t exactly get on top of your roof with a snow shovel. If you have an asphalt roof, you run the risk of doing serious damage to your shingles, which can cause your roof to leak afterwards—and all kinds of havoc as a consequence.2

If you don’t have the proper equipment to remove the snow yourself, hire a roofing contractor to safely handle the removal for you. It generally only costs about $100 to $300, and it will save your roof a lot of wear and tear.[3]

Install an ice and water shield

We suggest you install an ice and water shield over the first four feet of roof, on top of the sheathing—not just along the edges near gutters. This adds a second layer of protection against leaks and moisture where ice dams may occur, so if water gets in below the shingles the sheathing is watertight.

Another reason to add an ice and water shield is it seals around nails, unlike tar paper, roofing felt, or asphalt paper. If you have shingles on your roof, as most North American homes do, for every nail that goes through the tar paper there’s a tiny hole — an open invitation for water in your attic.

Check your attic (and garage) after a storm too. If you see frost on the sheathing it’s not a good sign. It means your attic isn’t properly vented for your specific insulation type or it is lacking insulation all together, which could lead to mold or rot. If you see any signs of mold or rot in your roof, call a professional remediation company.

Your roof and attic are crucial when it comes to protecting your home over the winter. Please contact us to schedule an appointment to make sure your insulation package is up-to-date.
