Architectural asphalt
Laminated shingles give a dimensional appearance. The exact product has its own application instructions and rated performance. Underlayment and flashing still control the connections beneath it.

A replacement should solve the roof system, not only change its color. We look at the covering, deck, flashing and ventilation so the work reaches the parts that need it.
Free roof inspections. Repairs, replacements and commercial roof help.
Repeated leaks in different places, widespread damaged shingles and deterioration across a slope are reasons to consider replacement. A single defect can still be a repair. The inspection separates those conditions and looks at how new work would connect to the rest of the property.
Removing the old shingles exposes the deck so unsound wood can be replaced before the new layers go on. A roof-over leaves that view closed and adds weight. Whether any recover is allowed or suitable depends on the existing layers, condition, code and selected system.
Review the repair alternative

The roof needs a continuous water-shedding system from the deck to the edges. A replacement brings these decisions together.
Remove the agreed layers and inspect the exposed wood. Replace unsound decking and resolve attachment or structural concerns before covering it.
Install the specified underlayment, eave and valley protection, flashing and drip edges with the correct overlaps. Wall and chimney details need their own attention.
Install the selected covering with its required fastening. Intake and exhaust are balanced with the roof design rather than adding a vent in isolation.
Disposal, site access, affected gutters and any concealed damage are part of the work conversation. Product and installation warranty terms come from their respective issuers.
Appearance matters, but the assembly, fastening and maintenance are part of the choice.
Laminated shingles give a dimensional appearance. The exact product has its own application instructions and rated performance. Underlayment and flashing still control the connections beneath it.
A test classification describes performance under a specific test. It does not make the completed roof immune to hail, eliminate maintenance or establish an insurance discount.
Standing-seam and exposed-fastener systems use different attachment details. Panel movement, penetrations and transitions need a system-specific design.
For a 2,000-square-foot roof surface, the architectural-asphalt planning scenario is $8,000 to $12,000 using October 2026 Kansas City metro inputs. The example includes one-layer tear-off, underlayment, eave and valley protection, needed flashing, ridge venting and haul-away.
| Change to the project | Effect on the scope |
|---|---|
| Extra layers or damaged decking | More tear-off, disposal or wood replacement than the base scenario. |
| Steep or complex roof geometry | More staging, cut material and detailed work around valleys, dormers and walls. |
| Different material or ventilation work | A separate system design or added intake/exhaust work changes the allowance. |
Roof area and living area are different. The roof-cost calculator lets you keep a known-surface example or use roof footprint and pitch, with the assumptions visible beside the result.
A project price needs measured roof area and the actual layers, access and connections. Decking discovered at tear-off is a practical reason for the scope to change, so it belongs in the replacement discussion before work starts.

No. Age helps frame the inspection, but condition and repairability decide the work. A localized defect on otherwise serviceable roofing can have a repair option.
Only the actual deck condition establishes that scope. The exposed deck is checked after tear-off, and unsound areas need replacement. A new covering cannot restore deteriorated wood beneath it.
A manufacturer product warranty addresses the covered material under its terms. Installation coverage addresses covered workmanship from its issuer. The covered defects, exclusions, transfer terms and remedies can differ.
