Building expert calls for reinforced roofs

As the country engages in post-hurricane recovery, property experts are urging homeowners and contractors to strengthen roof structures while undertaking repairs, warning that taking shortcuts could lead to greater losses in the next hurricane.

Kerry Scott, head of real estate and properties at JN Properties, said that repairs to zinc roofs should entail tightening fasteners and adding hurricane straps to increase homes' ability to withstand the next hurricane. His company manages more than 130 properties across Jamaica.

Scott explained that the strength and stability of a roof are determined by its design, quality of materials, and level of maintenance.

"Roofs that survived tend to have been built using hurricane-rated materials and reinforced connections between the roof and the walls of the structure. Roof designs that include secure truss connections and hurricane straps, distribute wind forces more evenly, reducing the chance of uplift. When these structural elements are properly installed, the roof has a much greater chance of staying intact even under intense pressure," he said. Scott stressed that regular inspection and maintenance are critical.

"A small leak or a lifted sheet might not seem serious in calm weather, but it can become a major failure point during a storm. Homeowners should not only repair visible damage but also check for hidden weaknesses caused by stress from the recent hurricane," he said.

Although some residents were fortunate that their roofs remained intact, Scott cautioned against complacency.

"Just because a roof survived this hurricane doesn't mean it's fully sound. Strong winds can loosen connections or create hairline cracks that weaken the structure. A professional inspection can help identify issues before they become costly or dangerous," he advised. Scott pointed out that material choice also plays a critical role in roof performance. He said galvanised steel, concrete tiles, or modern composite materials tend to offer superior durability.

"Lightweight or deteriorated materials are more vulnerable to be blown away. It is therefore important to invest in durable options rated for high wind resistance and ensure they are installed by qualified professionals," he said.

For homeowners considering long-term upgrades, concrete slab roofs offer added protection but come with higher costs and maintenance needs.

"A well-constructed concrete roof can withstand hurricane-force winds and serve as a foundation for an upper floor. However, these roofs must be properly waterproofed and inspected for cracks to prevent leaks and structural damage."

One homeowner who learned the value of that investment is Verna McBean, a retired teacher from Yardley Chase, St Elizabeth. She lost her zinc roof during Hurricane Ivan in 2004 and again suffered damage during Hurricane Dean in 2007 before deciding to instal a concrete slab.

"The house would have been destroyed again if we had put on back the metal roof," said McBean, referring to Hurricane Melissa. She disclosed that she initially had reservations about slabbing her roof.

"When you are in a slabbed roof it's like [being] in a vault, so it was really difficult for me to make the decision to do the slabbing, but it was the best way out," she reasoned.

"I feel more comfortable and relaxed because I really don't hear the zinc being torn off."
