Owens Corning Home Additions & ADU Nationwide

Owens Corning Home Additions & ADU: The Pompano Beach Owner’s Guide

Rowan Construction Group Pompano Beach installs Owens Corning-compatible roofing and insulation systems for home additions and ADU projects, with typical installed pricing in Pompano Beach running $45,000-$130,000 for additions and $90,000-$220,000 for detached ADUs. We stock Owens Corning Duration, Oakridge, and Total Protection Roofing System components, and we carry written quotes - not phone estimates - to every site visit in Pompano Beach. Most Pompano Beach homeowners discover their existing Owens Corning system is failing when they spot granule loss in the gutters, feel uneven attic temperatures in the new addition, or notice the original roofer used a lower-spec shingle than the main house, creating a thermal bridge where the old roof meets the new structure.

Which Owens Corning Models This Applies To

Owens Corning organizes its residential roofing into tiered series, and the spec you need depends on what was originally installed on the main structure. The Duration series carries the SureNail strip - a fabric-reinforced nailing zone that resists blow-off in Pompano Beach’s 120-mph wind zones - while Oakridge is the laminated step-up from three-tab, and Supreme is the entry three-tab line. For additions and ADUs, the critical match point is not just color; it’s the thickness and exposure dimension so the new roof plane doesn’t telegraph through as a visible ridge where it ties into existing decking.

To identify your current Owens Corning shingle, check the underside of an end shingle in an overhang or gable end for the printed code, or look for the product name on original permit documentation filed with Broward County. The Total Protection Roofing System - Owens Corning’s complete assembly of underlayment, ice and water barrier, ventilation, and shingles - is what we specify for Pompano Beach additions, because mixing components from other brands voids the system warranty. We also source Owens Corning ProPink insulation for ADU wall and roof assemblies; the R-30 batts for 2×10 rafter bays are 9.5 inches thick, and compressing them to fit a 2×8 bay drops the effective R-value by roughly 15 percent - a gotcha we see in Pompano Beach garage conversions where the original garage roof was framed shallow.

Rowan Construction Group Pompano Beach is an independent contractor, not affiliated with Owens Corning. We specify their products because the documentation holds up in permit review, and because we’ve got fifteen years of installed data on how their laminates perform in South Florida’s UV load and salt air.

Signs Your Owens Corning Home Additions & ADU Is Failing

• Granule accumulation in gutters or downspout outlets. Owens Corning shingles shed granules as the asphalt binder oxidizes; in Pompano Beach’s high-UV climate, this accelerates after year 12-15. Heavy granule loss exposes the fiberglass mat, and the shingle becomes a water path instead of a water barrier. We check gutter sediment during every site visit - it’s a free diagnostic the owner can see without climbing.
• Thermal stratification - hot ceiling in the addition, comfortable main house. This usually traces to Owens Corning insulation batts that settled in vaulted ADU ceilings, or to missing baffles that let intake air wash over the insulation instead of passing through the vent channel. The fix is rarely more insulation; it’s restoring the ventilation geometry the Total Protection system specifies.
• Lifted or cupped shingle tabs at the addition tie-in. Pompano Beach’s afternoon thunderstorms drive wind from the east; if the original addition roofer hand-nailed outside the SureNail zone, or used staples, the tabs lift first where the roof planes meet because that’s where turbulence concentrates. We document this with photos from the ridge, not the ground.
• Staining on the addition ceiling after a wind event, but no visible shingle damage. The Owens Corning ice and water barrier may have been omitted at the valley or eave, or the self-sealing strip failed where old roof meets new. Water travels laterally on the underlayment before it finds a fastener hole or seam.
• Musty odor in ADU closets or behind knee walls. Owens Corning ProPink is hydrophobic - it doesn’t absorb moisture - but if the vapor retarder faces the wrong direction in a cooled ADU, condensation forms on the back side of the drywall. In Pompano Beach’s 75-percent-plus humidity, that’s a mold vector within two seasons.

Replacement Cost & What’s Included

Home addition roofing and insulation in Pompano Beach runs $45,000-$130,000 for attached additions, and $90,000-$220,000 for detached ADUs, with the spread driven by three factors: square footage, whether we’re tying into an existing Owens Corning system or specifying new, and the structural work required to match rooflines. A 400-square-foot master bedroom addition with a shed roof tie-in, Owens Corning Duration shingles, ProPink R-38 ceiling batts, and proper intake/exhaust ventilation typically lands near the lower third of that range. A detached ADU with full electrical, plumbing, impact-rated windows, and a standalone Total Protection roof assembly runs higher.

Every Rowan quote is a flat written price with line-item scope - under Clause 1 of The Haven Standard, no work starts until the number is signed. The quote includes Owens Corning material, permit fees for Broward County, demolition and disposal, and our 365-Day Done Right Promise. We pull permits and pass inspections; the photo record from every visit goes to the customer same-day. No change order proceeds without a signature, which is how we’ve kept 4,000-plus projects within a few percent of the original number.

DIY or Call Us?

There’s a short list an owner can safely check from the ground: gutter granule volume, attic hatch temperature comparison, visible shingle tab lifting, and whether soffit vents are blocked by paint or insulation. A phone photo of the gutter sediment and the shingle code from an overhang gets us 80 percent of the way to a parts list before we drive.

What goes wrong fast: walking a 6:12 roof in Pompano Beach’s afternoon humidity to check for hail damage, disturbing vermiculite insulation in a 1970s addition without testing, or compressing Owens Corning batts into a cavity shallower than the specified thickness. The Total Protection Roofing System has six components - underlayment, ice and water barrier, starter shingles, field shingles, ridge cap, and ventilation - and omitting one voids the warranty even if the shingles look fine.
