As a commercial building owner, you may need to inspect and make some simple roof repairs yourself. Having some basic knowledge of how to complete and make simple maintenance and repairs can save you time and money from a damaged interior. Here are some tips to help you look for and complete some basic repairs to your flat tar and gravel roof.
Your roof's drainage system is an important part for your roof, especially during a rain storm. The scuppers and drains installed on your roof need to be clear of debris, leaves, and twigs. When the scuppers become clogged with storm debris, they cannot drain water from your roof. Water will puddle and collect on your roof and can eventually work its way beneath the roofing materials and into your building's interior.
It is a good idea to also remove the exterior cover from scuppers to clean out any debris that may have found its way into and begun to clog the drain pipe. Use a pressure washer or a drain snake auger to spray and clear out any clog inside your roof drainage until you can see the water draining from the base of your roofing drains.
Check Roof Materials
While you are on your roof cleaning the scuppers and drains, look for any cracks or holes in the membrane material of your roof. Also look for any blisters where the membrane has lifted from the roof, as this can lead to a future leak. Sweep aside any loose gravel to help you inspect any suspected area of damage.
When you find any cracks, holes, or blisters within the roofing membrane, you can repair it yourself, or call a professional roofer to take care of the damage. To complete the repair yourself, you will need some roofing cement for repairing tar and gravel roofs and some membrane patching material. Sweep aside the gravel and clean the surface of the damaged area, then apply some roofing cement onto and several inches around the area of damage. Cut a patch the same size as the patched damage and apply it onto the damage.
To repair a blister, first, cut open the blister with a utility knife making an "X" cut and dry out the interior of the blister, then apply some roofing cement inside the blister to fill it. Close the flaps over the cement and cover the area of damage with additional roofing cement. Complete the repair with a patch to cover the repaired and cemented area.
