IKO Home Additions & ADU: The Orlando Owner’s Guide
An IKO home addition or ADU in Orlando typically runs $45,000 to $130,000 installed, depending on square footage, foundation work, and whether you’re tying into existing roof lines or building a detached structure. Most owners call us after they’ve lived with a space that no longer works: a garage that’s too hot half the year, a spare bedroom that became a storage closet, or a property that could generate rental income but doesn’t have the square footage. We’re Sawyer Remodel Orlando, and we handle the full scope, from site prep and slab pour to framing, roofing, drywall, and finish work. One call to (850) 809-0306 gets you a written price before anything gets torn apart.
Which IKO Models This Applies To
IKO is a shingle and roofing products manufacturer, so when we talk about an IKO home addition or ADU in Orlando, we’re talking about the roofing system that ties the new structure into your existing home. The two lines we work with most are IKO Cambridge and IKO Dynasty, both architectural shingles rated for Florida’s wind and rain. Cambridge is the workhorse: solid performance, mid-range cost, and available in colors that match most Orlando neighborhoods. Dynasty has a heavier profile and a higher wind rating, which matters if you’re in a newer section of Lake Nona or Horizon West where exposure is open and afternoon storms hit hard.
One compatibility gotcha: if your existing roof has IKO Cambridge in a color that’s been discontinued, you won’t match it exactly with a new bundle. We flag this before we order anything. Sometimes the right move is to reroof the entire structure at the same time, which we price separately so you can decide without pressure. We also stock aftermarket underlayment and flashing components that meet or exceed IKO’s installation specs, which keeps the warranty valid without forcing you into a single supplier’s accessory line.

Signs Your IKO Home Additions & ADU Is Failing
- Shingle granules in the gutters. If you’re cleaning out your gutters and seeing what looks like coarse sand, the shingle surface is breaking down. In Orlando, UV exposure accelerates this faster than in northern climates, and it’s usually the first sign the roof on your addition or ADU is past mid-life.
- Curling or lifting shingle edges. This happens when the asphalt core dries out and the shingle loses its grip on the nail line. It’s common on ADUs that were reroofed with the cheapest bid years ago, and it’s a leak waiting for the next hard afternoon storm.
- Water stains on the ceiling inside the addition. By the time you see a stain, water has already traveled through the shingle, underlayment, and decking. The damage underneath is always bigger than the stain on the surface.
- Missing shingles after a storm. Orlando gets its share of wind, and a missing shingle on an addition means the underlayment is now exposed. It doesn’t take long for UV to break that down and let water through.
- Rust or corrosion around roof penetrations. Vent pipes, skylights, and exhaust flues on ADUs often fail at the flashing first. The shingles may look fine, but the metal around the penetration is where water finds its way in.

AfterReplacement Cost & What’s Included
A full IKO home addition or ADU build in Orlando ranges from $45,000 on the low end for a small, simple bump-out to $130,000-plus for a detached ADU with a bathroom and kitchenette. The spread comes down to three things: foundation type (slab on grade is less than stem wall or pier), roof tie-in complexity (attaching to an existing hip roof costs more than a simple gable), and finish level (builder-grade fixtures versus custom tile and cabinetry).
We give you a written line-item price before any work starts, so you see exactly where the money goes: site prep, framing lumber, IKO shingles and underlayment, drywall, electrical rough-in, plumbing, and finishes. No change orders unless you change the scope. Our 365-Day Done Right Promise covers the work for a full year after close-out, and the IKO shingles carry their own manufacturer warranty, which we register for you.
DIY or Call Us?
If you’re talking about the roofing portion of an addition or ADU, DIY is a bad idea. Roof work means heights, power tools, and a surface that gets dangerously slick in Orlando’s afternoon rain. A fall from a single-story roof puts you in the hospital with broken bones at best, and a bad flashing job leaks slowly enough that you won’t find it until the decking is rotted. Even on ground level, tying a new structure’s roof into an existing one requires getting the underlayment lap direction right, and if water gets behind the shingles, the whole addition has to be torn down to the studs.
What you can do yourself: check the ceiling inside for stains after heavy rain, clean your gutters so water flows away from the fascia, and keep tree limbs off the roof surface. Beyond that, this is work for a crew that does it every week. Call (850) 809-0306 and we’ll send someone out to look at it for free.
FAQs
An IKO Cambridge or Dynasty roof installed correctly in Orlando lasts 15 to 25 years, with Dynasty on the upper end because of its heavier construction. Florida sun and humidity age shingles faster than the manufacturer’s national averages, so we tell clients to plan for replacement closer to the 15-year mark than the 25-year mark. Call (850) 809-0306 for a free roof assessment.
Yes, if the damage is isolated to a small area and the surrounding shingles are still sound, we can cut out and replace just that section. The catch is color matching, because discontinued IKO colors won’t match new bundles. We’ll tell you straight whether a patch will look acceptable or whether you’re better off replacing the whole slope. Estimates are free at (850) 809-0306.
A standard ADU takes 4 to 8 months from permit to final inspection depending on your municipality’s review timeline. Orlando and Orange County have different permitting processes, and some neighborhoods require additional zoning review. We handle the permits and keep you updated with photo progress at every stage. Call (850) 809-0306 to talk through your timeline.
We maintain a local supply relationship with IKO distributors in the Orlando area, so we can typically get materials on site within days, not weeks. For discontinued colors or specialty lines, we source through our network and confirm availability before we schedule the job. Either way, you’ll know the material pricing before you sign anything.
If your IKO home addition or ADU needs work, or you’re planning a new build, call (850) 809-0306. We’ll walk the property, give you a written price, and you’ll know exactly what it costs before anything starts. No surprises, no phone tag, no games.
