Prep your home for Hurricane Season


The Atlantic hurricane season occurs each year, from June 1 to November 30. If you haven't prepped your home by early September, sometimes it can be too late. Hurricane hazards come in many forms, including storm surges, high winds, tornadoes and flooding. It is imperative for families, businesses and communities alike to institute a plan addressing all of these hazards.

Take action before, not after

Understand your roof and its warranty

Read your roof’s construction and warranty paperwork. Understanding how your roof has been constructed is the first step to evaluate its current condition and determine if repairs or upgrades are required. Understanding the terms and conditions of your warranties may prevent you from making changes that will void the warranty.

Look for problem areas on your roof

Loose or curled shingles, broken or missing tiles all warrant repair. Also inspect the flashing, drainage system, and accessories such as vents and skylights Ask a trained roofing professional if additional reinforcements to the roof structure such as additional fasteners or hurricane clips, are required.

Beyond the roof, a home’s doors and windows can also become major leak zones. Most commonly this is due to breakage of windows due to flying debris. However, even if the windows and doors are well shuttered, wind-driven rain can be blown into the house at these points, especially if they have not been properly flashed and weatherproofed. The following are some signs of water damage:

  • Leaks or breaks in seams around window trim and sills
  • Uneven doorframes
  • Discolored plasterboard
  • Peeling wallpaper
  • Chipped or cracked stucco finishes
  • Mold, mildew, or rot in the walls, insulation, and electrical systems
  • Missing, cracked, or blistered paint inside the home


Use the right products

If repairs are needed, don’t skimp on quality to save a few cents. Much of the damage associated with hurricanes and other serious storms results from water entering the home when roof coverings or siding is blown off. This is why it is imperative that you have a secondary layer of waterproofing protection underneath the shingles and siding. If proper protection measures are not taken, the resulting leaks are the main cause of interior damage, as well as potential causes of rot and mold. Rot and mold can lead to major structural damage and even potential health problems for homeowners.

ROOF: FEMA has published recommendations for the use of fully-adhered roofing underlayments, such as Grace Ice & Water Shield®, as an enhanced secondary water barrier for homes in both coastal and inland hurricane-prone areas. In the event roof coverings are blown off or water manages to get underneath your shingles, these underlayments are the key to preventing water infiltration.

WINDOWS, DOORS & MORE: Flexible flashings such as Vycor® line of flashings, can be used to seal the most vulnerable spots, including windows, doors, corner boards, and other non-roof detail areas. Highly conformable, self-adhering waterproofing membranes form a weather-tight barrier around unwanted openings in the wall sheathing system. GCP's website offers a home waterproofing interactive guide for more guidance.

Find a pro

Identify reliable, knowledgeable professionals that can perform work safely. It’s usually best that all inspections, maintenance and repairs are completed by trained and experienced people. You should demand that they use high quality materials. The amount of money you can save by selecting less expensive lower quality products is insignificant compared to the damage caused by water infiltration. Check this infographic for more information on selecting the best roofing underlayment for your home.

You should find a trusted building professional to repair your storm damage so that you have a strong roof over your head, protecting your wallet and home from future storm damage.

Ohio Architect's Home: From the roof to the windows

​Turning environmental challenges into design wins for a truly interesting lakeside home

"That was part of the fun—working through priorities and challenges and turning them into solutions that are exciting and add a lot to the quality of the architecture and the space," said Dan Meehan, an Ohio Architect who's designing and building his dream retirement home on Lake Erie.

Living on a Great Lake like Erie means living with extremes. Extreme beauty. Extremely captivating views of nature and the Cleveland skyline across the water. Also, extreme weather.

Architect Dan Meehan had to pull out all of the stops so that his dream retirement home would maximize these wonderful Lake Erie views, while soundly withstanding Lake Erie gusts and horizontal blowing rain.

Vycor® enV-S™ self-adhered weather resistive barrier completely wraps and seals under all of the siding of his house. Ice & Water Shield® protects the whole roof.

"The roofers didn't cut super long strips (of Ice & Water Shield®)," Dan said. "They cut strips they could manage between three guys and still got the whole roof covered inside of two days."

Dan bridged between the Ice & Water Shield® and the custom Boral eve molding with a metal drip edge. That was a design decision, he said, for a more interesting roof detail than gutters.

"Once the roof is on, I'm going to have the carpenters start installing the windows," he said. "It's good that the roof will be completely on so that there's nothing that could blow off and break a window."

The wind would have to blow off a pretty big roof piece, however. Dan's installing heavier-gauge extruded aluminum exterior windows, which have a "really high" wind rating, he said. Throughout the whole house, he's installing both double-hung and casement windows.

The double-hungs are really the stars of Dan's window show. They have a thick cross section and are huge—4-foot-4 wide by nine feet tall outlets to the wonderful world of Lake Erie.

"In areas where we're going to sit inside a lot, and look out, I didn't want to have screens on the inside," Dan said. "It doesn't look as nice, better to see the wood molding. I wanted to use double-hung windows, instead of casements, where we'd be enjoying the views, since we could put screens on the outside."

Dan also skewed the lake side of the house by 10 degrees. As he, his wife and guests gaze out through those cathedral sized double-hungs, some windows will feature the private park and lake, others will showcase the Cleveland skyline.

"It's a design trick that I made up or this house."

Ice & Water Shield® over the whole roof

In the beginning of Dan Meehan's architectural career, he used Ice & Water Shield® on every residential project—two courses around the eves and a course up every valley and hip. Those houses are still around 40 years later and doing great, Dan said.

It wasn't surprising, then that he was "all in with Grace Ice & Water Shield® for (his own home's) project."

With the concern of severely blowing winds and horizontal rain, Dan will wrap the whole roof in Ice & Water Shield®.

Now Dan and his wife will be able to enjoy the breathtaking lake view without worrying about weather damage.


Exclusive views of Lake Erie

Dan turned a challenging lot layout (only 45 feet wide) into an opportunity to build a unique design that capitalizes on unbeatable views of Lake Erie.

"The joy of designing your own house as an architect is looking at the site and combining that with how you live and your lifestyle," he said.

This is the second home Dan has designed for himself. Two decades ago, he designed a home in which his family grew up. Now, he's designing a retirement home for him and his wife.

"Our lifestyles changed. We're downsizing. And we want to spend a lot of time enjoying the views."
