When a roof leaks, it means that water is entering through a couple possible areas. It could be getting through the actual roofing material or membrane that was used when your roof was installed, or it could be getting in through “protrusions” such as skylights, metal or brick chimneys, lead or aluminum vent stacks, roof drains, etc.
If you see visible dampness or any mold or staining, it does not necessarily mean that the leak is directly above. Leaks can develop on one side of your roof and may travel a fair distance before they become visible on the inside. It could also be a direct result of having inadequate ventilation or air circulation.
As soon as you notice a leak or any symptom of a developing leak, it is in your best interest to have it inspected by a professional to possibly avoid the larger expenses of repairs to both the roof and inside items (drywall, painting, carpet cleaning).
For tar and gravel leaks, finding the cause is complicated by the hidden membrane system. In a traditional tar and gravel roof the waterproofing membrane is covered by a protective layer of asphalt and gravel. This gravel layer commonly hides the membrane deficiency.
Regular maintenance is key to preventing the general inconveniences that are associated with a roof leak. If you need professional advice and/or workmanship, please do not hesitate to contact us.
