ASHLAND — In the aftermath of the Oak Knoll Fire, Ashland Fire & Rescue Chief John Karns is proposing that all new homes in Ashland have fire-resistant roofs and that flammable roofs on existing homes be phased out within 10 years.

The proposals are part of a series of recommendations that likely will be considered by the Ashland City Council before the end of the year.

The Oak Knoll fire burned 11 houses, causing more than $3 million in damage and making it the worst residential fire in Ashland in more than a century.

Some of the homes that were destroyed had flammable wood shingles. With the help of helicopter water drops, firefighters were able to stop the advance of the fire at a house with a fire-resistant roof.

Karns said that when an ember lands on a flammable wood-shingle roof, the consequences can be disastrous for that house and its neighbors.

"You have what is virtually a small lumber yard on your roof. The amount and size of embers a wood-shake roof puts up really do endanger the houses downwind of you," he said.

Ashland already requires people who build in the Wildfire Hazard Zone to have fire-resistant roofs. The zone is located high in Ashland's hills, where homes meet the forest.

Karns said that while the forested hazard zone has received a lot of attention, the Oak Knoll fire showed that all 6.5 square miles of Ashland are at risk.

Allegedly started by a homeless man, the Aug. 24 fire began just outside city limits on undeveloped land covered in dry grass and weeds. It then jumped Interstate 5 near Exit 14 and tore into a neighborhood inside the city limits.

Ashland saw other grass fires this summer, although firefighters were able to put those out before they could destroy homes.

Karns acknowledged that phasing out flammable roofs on existing houses within 10 years would be costly for many residents. Most roofs last longer than 10 years, so some people would have to replace their roofs more quickly than they otherwise would.

Replacing a flammable roof with non-wood Class A roofing materials would cost between $6,000 and $20,000 or more, depending on the size of the house and other factors, Karns said.

He said the fire department likely will choose a number of houses as examples, get specific information about roof-replacement costs, and present that data to council.

Karns suggested there could be hardship provisions for those who can't afford to replace their roofs. The city could be more lenient if the homeowners had taken other steps to reduce fire risk on their property.

Karns also is proposing that Ashland Fire & Rescue work with the state fire marshal and the State Building Codes division to either require or allow local jurisdictions to mandate fire sprinklers in new houses and in structures that are remodeled.

Unlike fire alarms that are triggered by smoke and can go off for minor problems such as burned toast, Karns said fire sprinklers are triggered by extreme heat and won't go off by accident and cause water damage.

"That's a common, common concern almost everyone has," he said.

For a new home, installing a sprinkler system would cost about $1.50 to $2 per square foot. Costs for homes with ornate ceilings and trim could be about $3 per square foot, Karns said.
