Dealing With Potential Metal Roof Wind Damage in Corpus Christi TX

We've always regarded metal roofs as infallible and highly capable of withstanding all forms of hail, rain, and snowstorms. However, even the most durable roofing materials have their respective weaknesses because no roofing material is truly perfect. Metal roof wind damage is the next debilitating problem next to hailstorms.

In Corpus Christi TX, storms can get up to extremely high speeds during some hurricanes or local tornadoes appear. The strong wind can uproot any roofing material and not just cause metal roof wind damage. On the other hand, manufacturers pay attention to every detail that helps secure their roofs against extreme wind speeds. A researcher explains this in-depth guideline in a professional roofing research journal.

Component Design and Metal Roof Wind Damage

The panel manufacturer has the responsibility of designing a panel, batten (where used) and clip system that is capable of providing the load resistance that is published in its literature. (For panels rolled by the contractor, the contractor can be considered the panel manufacturer. However, the manufacturer of the roll-former should be responsible for designing a suitable panel and clip system and publishing load data)

Panel performance is a function of the panel profile, metal thickness, type of metal used, connection to the clips and ability of the panels to remain seamed or locked.

Clip performance is critical to the success of a metal roof system; a key aspect is the clip's ability to remain latched to the panel. The clip/panel interlock design should be sufficient to hold the panel even when the panel is deformed greatly under design loads. The clip also should be stiff enough to avoid harmful deformation.

Technically speaking, you have a highly-durable roof capable of withstanding all forms of wind damage. However, why is it that some experience extreme metal roof wind damage in the midst of a powerful hurricane while some remain intact?

Material and manufacturer specifications are about 70% of the total guarantee your metal roof will function as they intended during a storm. The remaining percentage relies heavily on the installation procedures, moving parts security, and other roof installation principles requiring the full attention of Corpus Christi TX's finest roofing contractors for metal roof materials. Classic Metal Roofing Systems has a great discussion on these factors.

Construction's Key Role in Reducing Metal Roof Wind Damage

The construction of the actual structure also has a bearing on roof system performance. If under the duress of severe winds, the structure is moving a great deal, it can be easy for the roof system to be jeopardized by that movement, and to eventually fail.

Ventilation

While structural stability and movement can go all the way down to foundation deficiencies, there are also things in the attic that have an impact. For example, if an attic has a great deal of intake ventilation but insufficient attic ventilation, then pressures in the attic can cause the roof decking to move or even separate from the rafters and framing. High attic pressures can also cause the structure’s ceilings to collapse, dropping drywall, insulation, wiring, and other home components into the living space.

Fastening

Studies of hurricanes have led to the requirement of more secure fastening and strapping of roof decks to be done in hurricane-prone areas, and we see benefits to that after major storms. Though, again, improper attic ventilation can then cause pressures to build in the attic resulting in collapsed ceilings as the ceilings can now be far less strong than the roof deck.

Roof fasteners also play a major role in performance and will be dictated by any roofing material’s wind uplift evaluative tests. While fasteners are just one component of the overall system, those folks in wind-prone areas want to make sure that their roof is installed with the same (or superior) fasteners that were used in testing of the roof system.

Installation Matters

Proper roof installation is critical. (Continued)

Lastly, you'll want to detect wind damage. While most wind damage is observable easily if it carries off a sizeable panel off your roof, some wind damage you can only see if you venture up your roof. SLP Roofs has a great guide on how to inspect your roof for minor and major wind damage even if it isn't a metal roof.

Wind Damage Inspection

If Your Roof Has Been Damaged by Strong Winds, Your House is Vulnerable to Roof Leaks.

To assess if you require roof wind damage repair, there is an easy inspection you can complete to gauge the state of your roofing. Inspect your roof system to see if there is any unsecure

d or removed material. These bits may have been severed by high winds, leaving your roof undefended. Curling, damage, and water retention of your remaining roofing shingles can be an indicator that your roofing system structure is damaged and may have a leak. Debris and tree limbs may also leave dents on the surface. While there is a surplus of directly apparent damage you may find on your roofing, some damage can lie buried underneath the layers of your roofing system structure. (Continued)
