Disaster recovery and restoration can be veiled in mystery to the many who have not undertaken specific training. This glossary explains technical terms to assist both report writing and the understanding of those technical terms so often misunderstood.
Definition
| Algae: |
A group of one-celled, free floating green plant life often found in aquatic ecosystems. Point of Interest Note: Algae is often found on buildings where sufficient sunlight (photosynthesis), humidity/moisture and organic nutrients exist. When identified, algae on buildings are on the outside surface of a walkway or a garden, and grow on the side and roof of a building. Investigation Note: The prsence of algae may be an indicator that there is mold and water damage behind the building substrate. Like mildew algae will flourish where is an adequate source of moisture and a nutrient such as dust and dirt. |
| Algae: |
A fresh water plant associated with fungi, which forms a scum or film on the surfaces of the ventilation recirculated water apparatus and drain pans, interfering with fluid flow and heat transfer. The presence of algae build up is an indication of poor maintenance and possible poor indoor air quality. |
| Roof Caused Floods: |
Roof Caused Floods: Resulting roof floods are usually caused by a downpour and wind driven rains. Rain damage to a roof is due in part to the weathering of the roof covering, sheathing, membrane or tiles. Other issues which allow roofs to leak are a result of a construction defect, such as to the ridge, ridge vents, valley, flashing, hip, starter course, eave, metal drip edge, gable vents, rake, to the underlayment; and poor maintenance that results in a leaking roof are a result of algae build-up on roofing materials, leaves on roof and in rain gutters, missing or damaged flashing, cracked or rotten shingles, loose and missing shingles, rotting underlayment and decking, curling and blistering, wood rot on fascia board and end boards, missing rock and granules. | The Disaster Advice Glossary and its contents are the protected copyright of Disaster Advice
