Tracking Down Roofing Issues

When Is Wind Damage Severe Enough To Warrant Roof Replacement?

As hurricanes, tornadoes, and wind storms roll through communities across the country, serious damage to roofing materials are leaving homeowners confused about the best way to approach repairs. Some damage is best patched with a little underlayment and a few shingles, while other forms of damage are severe enough to warrant an entire roof replacement. Determine what to ask your insurance company to cover by estimating the damage yourself and with the help of an experienced property inspector.

Sheathing Lift and Damage

A residential sloped roof consists of a surface material, such as asphalt shingles, over a layer of underlayment and a plywood layer known as the sheathing or decking. This is the part of the roof that sits directly on top of the trusses or rafters. When wind flows into your home through a broken window or open door, lift is created that pushes upwards against the sheathing. A single corner that lifts can be patched, but when a third or more of the roof has lifted up and torn away from the framing, a roof replacement is likely the only way to completely prevent future leaks and drafts.

Extensive Shingle Effects

Again, shingle damage due to high winds can vary greatly in scope and severity. A few torn or cracked shingles are easily replaced by a roof repair technician, while a roof that is mostly bare requires just as much work as a full replacement to be restored to intact status again. If your roof inspector says that wind damage has shortened the lifespan of every shingle on your roof, it's better just to replace them all rather than wait until they fail and deal with the secondary issues like leaks and rot. Many states follow a 25% rule for insurance claims, stating that roofs where more than a quarter of the covering is damaged must be replaced rather than simply repaired.

Severe Water Penetration

Storms bringing heavy winds that damage roofs also tend to generate a lot of rain fall, or even snow and ice accumulation. When shingles are missing and the sheathing and rafters of the roof become soaked with water, roof replacement may be necessary. Sometimes it takes weeks to plan a roof repair after a major storm, and rot can develop in a surprisingly short amount of time. It's better to tear out waterlogged materials and start with fresh ones rather than trying to dry them or reinforce them after the fact.

Design Issues

Did your roof suffer from wind damage due to a design flaw, such as a lack of wind resistant tie-down straps or corroded fasteners allowing shingles to come loose? It's better to address these long-term issues with a replacement process now instead of waiting through another wind storm that causes as much damage or more. Many older homes are lacking in the modern storm-proofing safety features that are required now for new construction. Bringing your home into compliance with today's building standards is worth the cost of a roof replacement.

Rafter and Truss Failure

Don't forget to have the roof inspectors check the rafters and trusses from inside the attic space to make sure wind lifting and shearing forces didn't damage them. A single damaged rafter or truss increases stress on the rest of the frame of the roof and house, resulting in a higher chance of serious damage during future storms and other natural disasters. Prompt repairs of major structural elements like the trusses or rafters is always necessary to keep your home safe for occupation. If more than a single truss or rafter is damaged, a roof replacement may be necessary so the repair crew can cut out the damaged materials
