Keystone, FL is a census-designated place in the northwest corner of Hillsborough County. It borders Cheval, Northdale, Citrus Park and Westchase, and it’s big: about 39 square miles, roughly four of them water. Addresses use ZIP codes 33556 and 33558.
About 25,200 people live here, and roughly 92 percent of homes are owner-occupied. The Keystone-Odessa Community Plan, adopted in 2001 and reaffirmed in 2011, sets out the goal of keeping the area rural, with two-lane roads, dark skies, wells and lakes, with a density of one home per five acres.
The median home in Keystone was built in 1999. So most roofs here are on a late-1990s or newer house, often on a big lot, owned by someone who plans to stay. We plan roofs with that in mind.
Rural, but Still the County’s Permit
Keystone feels a long way from downtown Tampa, but roof permits here follow the same process as the rest of unincorporated Hillsborough County. Hillsborough County Development Services issues them through its HillsGovHub portal.
A re-roof gets a progress inspection during the work and a final inspection when it’s done. We file the permit, meet the inspector and keep the records with your job file. You can read about the process on the county’s HillsGovHub page.
Wind Across Open Water
Keystone has a lot of lakes, including Keystone Lake, a private lake of about 434 acres. Wind crossing open water has nothing to slow it down, so homes along the shoreline take the full force of a storm’s gusts.
On exposed homes we pay close attention to the edges of the roof, where wind uplift starts: drip edge, starter strips, ridge caps and the first courses of shingles. During Hurricane Milton in 2024, gusts of 80 to 100 mph were reported across the region. A roof installed to its high-wind specification has a much better chance in conditions like that.
Complex Rooflines Take Care
A large custom home usually has a large roof, often with more hips, valleys and dormers than a typical subdivision house. Every one of those intersections is a place where water can get in if the flashing is rushed.
We measure carefully, account for the waste that complex rooflines create, and give you an itemized estimate so you can see where the cost goes. If you’d like to spread the cost of a large replacement out, ask about roof financing.
Is Metal Right for Your Property?
Rural properties are a natural fit for metal roofing. A well-installed metal roof sheds heavy rain quickly, resists wind when it’s fastened to spec, and lasts for decades. That suits owners who plan to stay put.
Metal isn’t for every house or every budget. High-wind architectural shingles from Owens Corning or GAF remain a strong choice, and we’ll price both so you can compare.
Late-1990s Roofs Coming Due
A house built around 1999 may still have its original shingle roof, now more than 25 years old. In Florida sun, that’s about as long as most shingle roofs last. Look for bare spots where granules have worn away, curling edges and stains on the ceiling.
Even if the roof isn’t leaking, an inspection now lets you plan a replacement on your schedule instead of after a storm. If it still has years left, we’ll say so.
Storm Damage on a Big Property
After a storm, check the roof from the ground first. Look for lifted shingles, missing ridge caps and debris that may have blown in from across the property. Don’t climb a wet roof.
If water is getting in, our emergency roof repair crew can dry in the opening the same day. Then we inspect the whole roof and document the damage with photos for your insurance claim.

Frequently Asked Questions
Who issues roof permits in Keystone?
Hillsborough County Development Services. Keystone is unincorporated, so there is no city building department involved.
My home faces a lake. Does that change how the roof should be installed?
Homes exposed to open water get stronger, steadier wind. We focus on edge metal, starter courses and ridge caps and install to the manufacturer’s high-wind specification.
Is a metal roof a good idea in Keystone?
It often is for owners planning to stay a long time. We’ll price metal and high-wind shingles side by side so you can decide.
My house was built in the late 1990s. Is the roof original?
It may be. County permit records can show whether it’s been replaced, and an inspection will tell you how much life it has left.
Can you finance a large roof replacement?
Yes, we offer roof financing options. Ask when we give you your estimate.
