3 Signs that You Should Replace Your Flat Roof
You have a flat roof and you are wondering when you are going to have to replace it. Unlike a peaked roof where you can see the shingles coming apart, you will have little visual indication that your flat roof is worn out. With a flat roof you have to watch out for leaks especially. The maintenance of your roof will have a lot to do with how long it lasts.
When you have a flat roof there are some thing you need to do to keep it in good shape and not need to be replaced so often. One is getting rid of standing or ponding water within 48 hours after it appears. Using a squeegee push all the water off or a shop vacuum to remove the water. Standing water will cause the roof to absorb the water and buckle and leak. For larger roofs, you should have a roof vent or a roof pump that will automatically get rid of all the water that is stuck up on the roof. All roofs should be inspected routinely especially after a big storm.
Knowing When to Replace the Roof
Depending on that type of roofing you have, you can tell in several ways when it is time to replace the roof.
- If your roof has holes and it buckles and leaks into the ceiling, you will need to replace it.
- If you have a roof that is put together with panels and the panels have come apart and cannot be repaired, you will have to replace your roof.
- Inspect the vapor barrier to make sure it is still intact and not torn. If you find torn places in the moisture barrier and you have leakages coming into your home through the ceiling, it is a sign that you need to replace the roof.
- If you have a tar and rock covered roof and the wind has blown off the tar-paper and exposed the undercoat of the roofing, you should also probably replace your roof.
Caring for the New Roof
When you replace the roof make sure you coat it with a polyvinyl coating that will resist rain and wet weather. The undercoating is water and weather resistant but making sure you have a top coat is extra insurance. Make sure all your drains are unclogged and flowing free. During dry times, clean the roof of any debris that could clog your drains if it should rain. Also using a a white or light colored top coat will help to cool the building that the roof covers.
