Spray Foam Roofing Over Existing Roofs
One of spray foam roofing's practical advantages is its ability to recover an existing roof, often without a full tear off. Understanding this explains a key use of SPF. Here is how spray foam roofing works over existing roofs on a Decatur commercial building.
Recovering an Existing Roof
Spray foam roofing can recover an existing roof, applied over a suitable existing roof to provide a new roofing surface without removing the old one. This recover approach can be a practical option when the existing roof is a candidate. For a Decatur building, recovering an existing roof with SPF is a useful option, since it provides a new surface over the old. The foam goes over the existing roof. This recovering of an existing roof is a practical use of spray foam roofing, since SPF can be applied over a suitable existing roof to provide a new roofing surface without removing the old one, offering a recover approach that can be a useful option when the existing roof is a candidate on the commercial building.
Avoiding a Full Tear-Off
Recovering with SPF can avoid a full tear off, sparing the cost, labor, and disruption of removing the old roof down to the deck. When the existing roof is suitable, avoiding a tear off is a meaningful advantage. For a Decatur building, avoiding a full tear off is a benefit of an SPF recover, since it spares the removal. The recover skips the tear off. This avoiding of a full tear off is a benefit of recovering with SPF, since applying the foam over a suitable existing roof spares the cost, labor, and disruption of removing the old roof down to the deck, making the recover a meaningful advantage when the existing roof is a suitable candidate on the commercial building.
Adding Insulation in the Process
Recovering with SPF adds insulation in the process, since the foam that recovers the roof also insulates, improving the building's thermal performance as it provides a new surface. This added insulation is a bonus of the recover approach. For a Decatur building, adding insulation in the process is a benefit of an SPF recover, since the foam insulates as it recovers. The recover improves insulation. This adding of insulation in the process is a benefit of recovering with SPF, since the foam that provides the new roofing surface also insulates the building, improving thermal performance as part of the recover, an added benefit that comes with choosing SPF to recover an existing roof on the commercial building.
When a Roof Is a Candidate
Not every roof is a candidate for an SPF recover, since the existing roof must be in suitable condition, with a sound substrate and no problems that would compromise the foam. An assessment determines whether a roof can be recovered. For a Decatur building, understanding when a roof is a candidate is important, since the recover only works on a suitable roof. The condition determines candidacy. This question of when a roof is a candidate is important to an SPF recover, since the existing roof must be in suitable condition with a sound substrate and no underlying problems that would compromise the foam, which an assessment determines before recovering rather than building over a roof that should be replaced on the commercial building.
The Lightweight Advantage
SPF's lightweight nature helps with recovering existing roofs, since the foam adds relatively little weight, making it suitable for recovering roofs where added weight is a concern. The light weight supports the recover approach. For a Decatur building, the lightweight advantage matters for an SPF recover, since it adds little load to the structure. The foam is light enough to recover. This lightweight advantage helps with recovering existing roofs, since the foam adds relatively little weight, making SPF suitable for recovering roofs where added load is a concern and supporting the recover approach on buildings where a heavier recover system would not be appropriate on the commercial building.
Recover or Replace
Whether to recover with SPF or replace the roof depends on the existing roof's condition and the building's needs, with recover suiting suitable roofs and replacement needed when the existing roof is too far gone. An honest assessment guides the choice. For a Decatur building, the recover or replace decision should be based on the roof's actual condition, since each fits different situations. Decatur Commercial Roofing assesses honestly and recommends accordingly. This recover or replace decision is part of considering SPF, since recovering suits a suitable existing roof while replacement is needed when the roof is too far gone, and an honest assessment of the existing roof's condition is what guides the right choice for the commercial building.
SPF as a Recover Option
Spray foam roofing can recover a suitable existing roof, avoiding a full tear off and adding insulation, with its lightweight nature supporting the approach. Whether to recover or replace depends on the roof's condition, which an honest assessment determines for a Decatur commercial building.
One thing worth understanding about spray foam roofing is how its continuous, monolithic nature compares to sheet based systems. Sheet roofing, whether single ply or built up, is installed in pieces that are joined together, and the seams where those pieces meet are common places for leaks to start over time. Spray foam roofing, by contrast, is applied as a liquid that expands into one connected layer with no seams across the field of the roof. For a Decatur building, this means the foam removes many of the joints where leaks typically begin, since the roof is one continuous surface. Decatur Commercial Roofing explains this characteristic when discussing roofing options with building owners, since the continuous coverage of SPF is one of the qualities that distinguishes it from sheet systems and contributes to its performance on the commercial building.
