When was Roof Cleaning in Peterborough of your building was inspected? If it’s been awhile, the roof could have problems lurking that need immediate attention. Some roof problems cause obvious signs such as leaks, while some produce subtle signs which are only detectable at first glance. In either case, leaving the problems unaddressed can cost you a small fortune when you finally repair them. If the roof on your own building has the problems listed below, an organization that specializes in commercial roofing should repair them quickly:

Buckled Panels

Roof panels buckle due to weather damage and poor installation. Whatever the cause, the buckling allows wind to blow within the panels, making them loose. Because the problem worsens, the panels start to fall off, often coming off in large sections when a storm hits. Buckled panels are probably one of the most commonly fixed problems by companies that perform roof repair.

Expended Screw Holes

Expanded screw holes are another problem for panel roofs. Over time, wind and fluctuating temperatures cause the screw holes in panels to widen round the screws that contain the panels in place. This creates an area where water can leak underneath the panels and soak the roof deck. Once the deck becomes saturated, the problem is costly to fix.

Blistering

Improper heating procedures and dry lapping cause hot bituminous roof systems to blister. Although small blisters seldom pose a problem, large ones can rupture and invite water to seep under the bitumen. Once the blisters form, warm weather typically makes them worse. As a result of humid subtropical climate in a few regions of the country, commercial roofing frequently experiences blistering.

Ponding Water

Blocked drains and improper sloping could cause water to assemble in small ponds on a roof. Repairing a blocked drain is easy, but fixing a sloping problem is more technical. Often, installing a taper insulation system to determine a new slope is the better solution. Through the rainy season, resolving ponding water is one of the most common types of roof repair.

Loose Flashing

Flashing prevents water from seeping in the crevice where in fact the roof abuts to protrusions such as chimneys and vents. Over time, most flashing should be resealed. If it is not, leaks may cause serious damage the deck and building interior. Most flashing problems are corrected during the course of scheduled maintenance.

Missing Mortar

Chimneys and high parts of brick walls that have parts of missing mortar may cause leaks. These leaks tend to be mistaken for leaks in the roof membrane, but a thorough inspection by way of a company that specializes in commercial roofing will reveal the true problem. Most sections of missing mortar can be repaired with basic tuck pointing procedures.

Conclusion

The problems above are a few of the most common reasons for roof repair. If they are corrected early, most problems are inexpensive to fix, but not addressing them until they cause serious problems may necessitate roof replacement. Having a scheduled maintenance agreement with a roofing company is the better solution to ensure problems are detected early.
