Waterproofing in Roofing and Building Development

Steps to Waterproofing

Concrete or tar roofs need waterproofing from time-to-time to ensure winter protection. Power wash the roof to clean it of any debris, but first fill in any cracks with mortar or asphalt, depending upon the type of roof. After washing, use primer on a concrete roof surface. Primer bonds to concrete and flows into any crevices in the roof and strengthens the concrete. Use seam tape on any cracks that you can still see. For large holes that can't be covered by seam tape, use concrete patches. Finally, apply a top coat of waterproofing material. For asphalt roofs, repair any cracks with hot or cold patch asphalt and when cured, cover the entire roof with the appropriate material to ensure a good sealing.

When renovating or remodeling, have a specialist review the current roof for waterproofing issues. If the roof is old, consider replacing the roof. Hidden storm damage deteriorates a roof and though you may not notice a leak in your roof, moisture could be seeping in without your knowledge. These problems are easily fixed and prevented through roof replacement or repair. When remodeling, roof construction must comply with the building codes that are already set and determined.

Before applying top coat or sealants to a roof, test the products on a small area to ensure proper adhesion. Allow the products to dry in the time allotted according to product directions. For best results, use products from the same manufacturer. They'll be designed to work in conjunction with each other.

Repair roof leaks, no matter how minor they seem. Leaking roofs lead to serious water damage and can weaken construction materials over a period of time. Roof rafters or trusses made out of wood and inundated with water can develop wood rot and mold, causing much more costly damage. Repair small roof leaks as they occur, and when the weather dries out, evaluate whether a complete waterproofing of the roof is needed. Ensure roof repairs are done by professionals or do-it-yourselfers with experience. Roof replacements or repairs on existing construction don't call for building inspections, as required when constructing a new roof.
