Skylight Leak Repair / Replacement In Withams VAA skylight is truly a lovely roofing feature. During the day it permits natural light to illuminate a living space and provides a wonderful view of the stars in the evening hours. When it is slightly opened, it in addition is great with regards to ventilation, allowing cool air inside as well as typically lowering your residence or local business living temperature. Inspite of these features, a skylight can end up being the source of a major water leak. Because a skylight is actually an independent device from your roof structure and is assembled utilizing many different materials, this can lead to several problems which, if not rapidly corrected, can certainly cause a roof to deteriorate rapidly.
Poor Insulation – During cold weather, small droplets coming from a skylight does not always mean leaking; often times it is simply indoor moisture condensation against a cold glass pane. The reason this happens is often due to a lack of insulation. Even though the moisture is not from the outside, it can still cause damage.
Loose Flashing – The mounting for this particular characteristic is in most cases sealed to the surrounding roofing materials utilizing thin metal sections called flashing that is secured with a sealer. Although this is the proper material for the job, continuous exposure to the weather conditions can cause it to loosen and allow water to leak in.
Poor Glass Seal – This transparent, glass material is seated and sealed to the frame using rubber-like seals; however, most of these products turn brittle over time due to constant exposure to the sun. Eventually, it can form cracks and become a source of water leaks.
Thermal Shock – A roof can expand when subjected to heat, which is known as thermal expansion. Because the skylight and frame are made from a different material than the roof, it will expand differently than the rest of the structure. The difference in this movement can cause gaps to form usually around the flashing, often leading to severe leaks.
Leakage Testing. If there are leaks before making any type of repairs since condensation can mimic a leak and repairs would be different, it is important to determine. Water could appear to be coming from the skylight when it is actually coming from another spot. Skylight Leak Tests should be performed to validate and eliminate other possibilities.
Any tests should be done during warmer weather so the roof is not slippery and dry. Take a hose up to the roof and run water from above the skylight so that all the flashing is soaked; then observe the underside for leaks. Any water below indicates a problem with the flashing. Next, run water directly over the glass. If water comes through gaps between the glass and framing, this means there is a glass seal problem.
The approach towards skylight repair on your Withams VA home or business depends on what is causing the leak.
Condensation – The best way to fix this issue is by injecting insulation foam into the space around the frame to prevent cold temperatures from causing this problem.
Loose Flashing – First determine what has caused the flashing to loosen; is it from poor sealant, strong winds, or thermal shock. If sealant is the problem, then repairing it is simply a matter of reinstalling a durable sealant; for either of the other two issues, a professional roofer should be contacted since the problem could be in the roof itself.
Glass Seal – This problem can be easily remedied by replacing the cracking seal with a silicone based one which has better resistance to brittleness and provides a better seal.
Frame – This component should also be examined for any problems such as gaps or a cracked, brittle or loose rubber seal.
In summary, repairing leakages caused by damaged skylights can be easily fixed. It is just a matter of finding the source and repairing it.
