Identifying Rotted or Soft Wood
Roof decking in Central Michigan is usually made of plywood or OSB sheets. Over time, moisture from small leaks or poor attic ventilation can cause this wood to rot. Signs of bad decking include a “spongy” feel when walking on the roof, visible sagging between rafters, or dark water stains on the underside of the wood in the attic.
If your contractor finds rotted wood, it must be replaced. Attempting to nail new shingles into soft wood is a safety hazard and will cause the shingles to pull loose in high winds.
Why “Roofing Over” is a Risk
In the past, it was common to install a second layer of shingles over the old ones to save money. This is a major mistake because it prevents the contractor from inspecting the roof decking Central Michigan weather may have damaged.
A full “tear-off” is the only way to see the true condition of your roof’s foundation. Removing the old layers allows the crew to find hidden rot, replace damaged sheets, and ensure the new shingles are nailed into solid, dry wood.
The Role of Fasteners
For shingles to stay on during a Michigan windstorm, the nails must “bite” into the wood. If the roof decking is delaminated or thin, those nails can easily pull out. Quality roof decking Central Michigan contractors use ensures that every nail stays put, maintaining the integrity of the wind warranty provided by the shingle manufacturer.
Local Concerns: Snow and Ice
Homes in Mt. Pleasant, Alma, Midland, and Clare must support heavy snow loads in the winter. If your roof decking is weak, the weight of a heavy snowfall can cause the roof to bow or even fail. Ensuring your decking is in top condition is a vital part of winterizing your home.
