Commercial Roof Restoration

Houston’s UV exposure and humidity break down flat roof membranes years before their rated lifespan.

Achilles Roofing & Exterior restores worn commercial roofs with reinforced coating systems that seal seams, stop ponding-water leaks, and add up to 10-15 years of service life at a fraction of replacement cost.

The Achilles Standard of Quality

Signs Your Commercial Roof Needs Restoration, Not Replacement

Ponding Water After Rain

Standing water that hasn't drained 48 hours after a Houston downpour softens membranes and accelerates seam failure long before the roof deck is compromised.

Chalking, Faded Coating

UV breakdown leaves a chalky residue on modified bitumen or TPO surfaces — a sign the existing coating has lost its reflective and waterproofing properties.

Lifting or Cracked Seams

Thermal cycling between 95°F afternoons and humid nights stresses seams and flashing details, opening small gaps that widen into active leaks.

How Restoration Works

What Actually Happens During a Commercial Roof Restoration

✔ Moisture-scan inspection to confirm the deck and insulation are dry enough to restore rather than replace
✔ Pressure washing and surface prep to remove chalking, debris, and biological growth common on flat Houston roofs
✔ Seam and flashing repair using reinforced fabric before any coating is applied
✔ Application of a fluid-applied acrylic or silicone coating system matched to your existing substrate

We document deck conditions with photos before coating begins, so you know exactly what was under the surface — not just what was sprayed over it.

Timing Around Houston's Storm Season

Why Restoration Timing Matters on the Gulf Coast

✅ Coating systems need a dry cure window — we schedule most Houston projects outside peak hurricane-season humidity (June–September) when possible
✅ Roofs restored before storm season gain sealed seams and flashing before wind-driven rain tests them
✅ We provide photo documentation and inspection reports that property managers can submit directly to insurance carriers

What Drives Restoration Cost

What Determines the Cost of Restoring a Houston Commercial Roof

Total square footage and roof accessibility (parapet walls, HVAC penetrations, drains)
Existing substrate — modified bitumen, TPO, EPDM, and metal each require a different primer and coating system
Degree of seam and flashing repair needed before coating can be applied
Coating thickness and warranty term selected for the property

We provide a written, line-item estimate before any work begins, so property owners can compare restoration cost against a full tear-off replacement.

Common Questions About: Commercial Roof Restoration

How do I know if my commercial roof qualifies for restoration instead of replacement?

Restoration is typically possible when the roof deck and insulation are dry, structurally sound, and free of widespread membrane failure. We confirm this with a moisture scan; if wet insulation covers more than roughly 25-30% of the roof, replacement is usually the more cost-effective option.

How long does a commercial roof coating last in Houston’s climate?

Most acrylic and silicone restoration systems are warrantied 10-15 years, though Houston’s intense UV exposure and humidity mean recoating or a maintenance inspection every 5-7 years extends that lifespan and protects the warranty.

Can a roof be restored if it already has standing water?

Yes, in many cases. Ponding areas are addressed with tapered insulation or additional coating build-up at low points before the finish coat is applied, which is often more affordable than re-sloping the entire roof deck.

Will restoration void my roof’s existing manufacturer warranty?

Not when the coating manufacturer approves the substrate. We verify compatibility with your existing membrane manufacturer before starting, and provide documentation your property management company can keep on file.

How much does commercial roof restoration typically cost compared to replacement in Houston?

Restoration generally runs 30-50% less than a full tear-off and replacement, since the existing membrane and insulation stay in place. Final pricing depends on square footage, substrate type, and the amount of seam or flashing repair needed.

How long does a commercial roof restoration project take?

Most single-building projects in Houston take 3-7 working days depending on square footage, weather delays, and the extent of seam repair required before coating is applied.

Can restoration be done while the building stays occupied?

Yes. Roof restoration is performed entirely from the roof surface with no interior access required, so tenants and daily operations are typically unaffected aside from occasional rooftop equipment noise.

What roof types can be restored versus what requires replacement?

TPO, EPDM, modified bitumen, and metal roofs are all common restoration candidates. Built-up (BUR) gravel roofs and roofs with significant deck deterioration are evaluated case-by-case and may need replacement instead.

How does hurricane season affect restoration scheduling in Houston?

Coating systems require a dry cure window, so we prioritize completing restoration projects before peak storm activity. Property owners can review regional storm outlooks through NOAA’s National Hurricane Center when planning project timing.

Do commercial roof coatings meet current building code requirements?

Coating systems are installed to meet manufacturer specifications and applicable provisions of the International Building Code as adopted by the local jurisdiction, including wind uplift and fire-rating requirements for the substrate.

What maintenance is required after a roof is restored?

We recommend a biannual inspection to clear drains and check seams, particularly after major storms. Routine drain maintenance is one of the most effective ways to prevent the ponding water that shortens coating lifespan.
