Roofs and Moisture
Roof Coverings Common in Jacksonville, FL
Jacksonville roofs mostly break down to asphalt shingle, metal, or tile, and each one lives with our humid subtropical weather differently. Shingle handles the afternoon thunderstorms fine but ages faster under our sun than up north. Metal and tile cost more upfront but shrug off decades in Duval County heat. What fits your house depends on age, pitch, and budget.
The gist
Architectural asphalt shingle covers most Jacksonville roofs, from Arlington to Mandarin, and lasts 20 to 25 years in our heat and afternoon thunderstorms. Older Riverside and Avondale homes sometimes still carry metal or clay tile, both good past 40 years. Flat-roofed Southside additions usually get modified bitumen, good for 15 to 20 years.
Shingle costs less upfront but takes the worst of Jacksonville's afternoon thunderstorms and eventually needs a full reroof. Metal costs more to install and holds up longer against wind, which matters near the St. Johns River and open Southside lots. A permit from the Building Inspection Division applies either way.
Questions & Answers
Frequently Asked Questions
Which roof covering lasts longest here?
Metal and composite outlast composition shingle by a wide margin, and both cost more up front. The honest comparison is not the warranty number on the wrapper but how the covering behaves in this climate: what holds moss, what sheds needles, what a low winter sun and forty inches of rain a year do to it. A thirty-year shingle and a thirty-year climate are two different things.
Can I put a different covering on than the one I have?
Usually, but not always without work underneath. Weight is the first question - concrete tile is several times heavier than shingle and the framing has to carry it. Pitch is the second: below about a 2:12 slope a shingle roof will not shed water and the roof has to be a membrane whatever it looks like from the street. An HOA may have a say in the third.
Does the covering change how often the roof needs looking at?
It changes what you are looking FOR. Composition shows its age as curling, cupping and granule loss. Metal shows it at the fasteners and the seams. Cedar shows it as splitting and cupping shakes with moss in the gaps. Tile rarely fails as tile at all - what fails is the underlayment beneath it, which is invisible until it leaks.
What is actually on most roofs around here?
Architectural composition shingle, by a long way, and it has been the default for new construction and re-roofs for decades. Cedar shake is on a good number of older houses and is usually replaced with composition or composite rather than renewed. Metal is a deliberate upgrade. Flat membrane turns up on a porch, a dormer or an addition rather than on a whole house.
