  • leak
  • The coatings can be used to repair any type of roof leak. (chinaqualitycrafts.com)
  • Every penetration on a roof surface is a potential leak, both of water and of heat energy. (buildings.com)
  • DEVELOP A PROGRAM The basic goals of a roof management program are to reduce long-term costs, reduce leak frequency and severity, and extend roof life. (docplayer.net)
  • In areas where the roof could become saturated by rain and leak, or where water soaked into the brickwork could freeze to ice and thus lead to 'blowing' (breaking up of the mortar/brickwork/concrete by the expansion of ice as it forms) these roofs are not suitable. (wikipedia.org)
  • occur
  • Moisture infiltration is the most critical performance failure that occurs in roof systems and it can occur for a number of reasons. (rbs-na.com)
  • In warmer climates, where there is less rainfall and freezing is unlikely to occur, many flat roofs are simply built of masonry or concrete and this is good at keeping out the heat of the sun and cheap and easy to build where timber is not readily available. (wikipedia.org)
  • Plywood
  • The roof deck may be constructed from plywood, metal decking or concrete or any other suitable material. (google.es)
  • Roof decking is usually of plywood, chipboard or OSB boards (OSB = Oriented Strand Board , also known as Sterling board ) of around 18mm thickness, steel or concrete. (wikipedia.org)
  • types
  • Effortlessly applied to all types of roof framework their liquid composition allows complicated shapes to get quickly and seamlessly waterproofed without removal, in several scenarios, to the existing substrate, that means less disruption during application. (blogolize.com)
  • systems
  • When considering roof systems, building owners and managers will tend to think from the top down, since the surfacing, flashing, and roof membrane are what you see (and repair when needed). (buildings.com)
  • The ballasted roof systems are far heavier than bituminous roofing, perhaps as much as 20 to 22 psf for high-wind areas, whereas the BUR would be only 4 to 6 psf. (buildings.com)
  • Bituminous roof systems for this application generally call for a base sheet, nailed or stapled to the decking. (buildings.com)
  • Just a few decades ago, thermal imaging of roofs (and of buildings in general) was introduced as a powerful weapon in detecting heat loss or gain in roof systems. (buildings.com)
  • exterior
  • Depending upon the construction, the roof deck may extend over the surrounding exterior walls or the roof deck may be exposed short of the exterior walls thereby forming a parapet wall, i.e., a low retaining wall at the edge of the roof deck. (google.es)
  • Interior
  • In addition to damage to the roof itself, roof problems are a common cause of interior water damage and mold. (docplayer.net)
  • 3 Defects from shrinkage, blisters, cracks and tears can allow moisture to penetrate the roof, often long before it is noticed in the building s interior. (docplayer.net)
  • leaks
  • Built-up roofs (BUR) might experience leaks due to flashing details that weren't fastened properly during installation. (rbs-na.com)
  • Shrinkage is associated with rubber roofs and can cause seams to delaminate and pull apart, causing leaks. (rbs-na.com)
  • A continually wet roof surface will significantly shorten the life of the membrane and can be a source of leaks. (docplayer.net)
  • skylights
  • The most obvious hazard is falling from the roof edge, but skylights and open hatches also present a fall hazard. (docplayer.net)
  • HVAC
  • The Corps has developed a method of preparing roof plans from the information gathered during the flyovers, using scaling techniques based on the known size of features on the roofs, such as HVAC units. (buildings.com)
  • Inspection
  • Regular roof inspection and maintenance go a long way. (rbs-na.com)
  • With regular inspection, repair and maintenance, the life of a roof can often be extended by five to ten years. (docplayer.net)
  • Use roof inspection checklists to document your roof s condition. (docplayer.net)
  • Be sure the inspection includes the following: Roof Edges The sheet metal and flashing at the edge of your roof should be securely attached and appear uniform. (docplayer.net)
  • During inspection, look for standing water on the roof surface. (docplayer.net)
  • water
  • Professional roof consultants are the ones most likely to take advantage of today's survey devices, whether they use the principles of infrared, nuclear, and capacitance to indirectly identify potential areas of trapped water. (buildings.com)
  • Ponding occurs when puddled water remains on a roof from rain, melted snow and ice, large amounts of condensation from mechanical equipment, or from failed rooftop water storage. (rbs-na.com)
  • they estimated that the load in the receiving water bodies from roofs and agricultural applications were in the same order of magnitude. (springeropen.com)
  • parapet
  • The wind uplift forces are not evenly distributed across the roof deck and the perimeter of the roof deck, particularly next to a parapet wall which encounters greater wind uplift forces than are encountered on the other areas of the roof deck. (google.es)
  • objective
  • The U.S. Corps of Engineers uses its ROOFER program (a remarkably objective, if not time-consuming, method of establishing relative roof condition ratings, fully digitized and computerized). (buildings.com)
  • repair
  • 2 Documenting deficiencies requiring corrective actions such as maintenance, repair or replacement Formulate a Plan Once the roof s condition has been assessed, you can formulate a plan. (docplayer.net)
  • Performance
  • The roofing industry has attempted to define roofing performance since at least 1974, when Robert G. Mathey and William C. Cullen collaborated to create the National Bureau of Standards (NBS) Building Science Series (BSS) No. 55 Preliminary Performance Criteria for Bituminous Membrane Roofing . (buildings.com)
  • decks
  • Of course, this meant the roof was fully adhered because that was all that was done in those days (on nailable decks, the base sheet might first be nailed, but all ply felts were bonded to one another). (buildings.com)
  • Wood and wood derivative roof decks are regional in their popularity. (buildings.com)
  • construction
  • These bituminous services are thoroughly utilized by our purchasers for safeguarding a pre-current construction from almost any seepage. (blogolize.com)
  • Although nature can sometimes cause punctures and tears, usually they are the result of sloppy construction over finished roofs, careless installation and maintenance, or foot traffic over the roofing membrane. (rbs-na.com)
  • often
  • Reports today often include digital photographs of important features, and may include recommendations or conclusions regarding roof condition. (buildings.com)
  • One that is not done often enough is to identify what items on the roof are no longer in service. (buildings.com)
  • As a result, correcting these problems can be difficult and costly, often resulting in roof membrane removal and replacement. (nrca.net)
  • edges
  • At roof edges, and with the A/C units or equivalent sq. packing containers on the roof: Use Eternabond RoofSeal White (it will extra readily wrap corners): Its achievable to utilize the Eternabond about the CAB/ROOF joint, even so the Eternabond is not really as durable for this joint. (blog5.net)
  • result
  • But a roof can fail as the result of wear, poor maintenance, and of course, the weather. (rbs-na.com)
  • Neglecting serviceable roofs will ultimately result in early failure and added expense. (docplayer.net)
