Roof Flashing

What is flashing? Flashing is used over joints in roof and wall junctions to divert water to prevent water seeping in and causing damage. Most flashing is made of metal and L Flashing (5 by 5) is the most common type of flashing in Florida homes. Flashing is one of the most important components of your roof and is vital to maintaining the structural integrity of your home. Florida building code describes the function of flashing as “Flashings shall be installed at wall and roof intersections; wherever there is a change in roof slope or direction. Existing vent flashing, metal edgings, drain outlets, collars and metals counterflashings shall not be reinstalled where rusted, damaged or deteriorated.”

Replacing flashing can be costly and difficult so many homeowners are reluctant to having their flashing fully replaced when a roof is replaced. In a similar light, some contractors, who may not have the experience or skill to replace flashing, avoid it to cut corners and low ball the customer with their estimate. Contractors may try and remove everything above the flashing (tar and shingles) that is damaged, but claim they left the flashing intact. When a roof is installed, a layer of tar is laid to adhere the shingles to the flashing. Over time, that tar hardens and crystallizes and is incredibly difficult to remove. If shingles need to be replaced, that tar has to come off as well. It is virtually impossible to remove all of the tar without damaging flashing. That would be the equivalent of removing a piece of tape to open a package and then resealing that package with the same tape. That may be fine for a box in the garage, but do you want to risk your home’s structural integrity to save a few bucks?

Realistically, the cost savings does not affect you, the homeowner, whatsoever. When a roof needs to be replaced, a homeowner’s cost is merely the insurance deductible. If your deductible is $5,000, and the insurance company says it will cost $10,000 to replace the roof, but your contractor identifies that the flashing needs to be replaced to meet Florida Building Codes at a total cost of $15,000, you still only pay your $5,000 deductible. Most insurance companies do not cover poor workmanship when damage is incurred, so it is important to know who you are working with and that they have a strong track record you can trust. If your insurance company approves a new roof claim and there are issues later on due to workmanship, the insurance company will not cover that subsequent damage. If it is not done right the first time, you will not get a second chance.
