FROM OUR PROJECT COLLECTIONCheck how the repair joins the existing surface
Different commercial roofing systems need different connection methods. Identify the membrane and earlier coating or patch layers before choosing a product. Surface condition and preparation affect whether the proposed patch or detail repair can bond or connect properly; a generic sealant description leaves that issue unresolved.
Work beneath the surface may be necessary if insulation is wet or decking is damaged. Ask how the extent will be established, whether testing or an opening is included and how any additional repairs will be priced. A localized surface repair should not conceal a known underlying condition simply to keep the initial scope small.
