Flat roofs notoriously have shorter life-spans than a traditional pitched shingled roof, which can last up to 35 years. Conversely, most flat roofs that are constructed with traditional materials, such as asphalt or tar, last 10 to 12 years. It is wise to regularly check a flat roof, as often the first sign of problems cause expensive water and mold damage to the interior of the home.
The main problem with repairing a flat roof is diagnosing why it leaked to begin with and whether it is due to a major design flaw.
A common misconception is that a flat roof is truly flat. It is necessary to have a slight slant or pitch to divert the water to the eavestrough or downspout. Flat roofs require a skilled professional that can properly pitch the roof and carefully install metal flashing. The smallest of holes has a potential to cause a leak, especially if water puddles form on the roof.
Many contractors will offer to patch the problem area and often this will temporarily solve the issue. But if your roof is past its lifespan, it may be wise to consider replacement.
That is why it is important to properly vet your roofing contractor when it comes time to replace your flat roof. Using the contractor with the cheapest estimate may cost you more money down the road. Verify that the contractor you hire has plenty of experience with flat roof installation and check with references to ensure they have been happy with the workmanship.
1) You have standing water on your roof well after it rains. This could mean that the roof has lost it pitch which spells disaster for the inside of your home.
2) The sealant on the seams and around all of your pipe collars is cracking, dry-rotting or deteriorating. The sun can be harsh on a flat roof and overtime the materials get dry and brittle.
3) You have holes in your roof that are not properly covered with drains or pipe collars. Any hole in a flat roof can lead to costly repairs down the road.
4) You have significant or consistent water damage inside your home. Consistent water damage to the interior of a home can lead to a variety of costly repairs, ceiling and wall cracking, mold and mildew removal, insulation replacement, electrical issues.
5) Your roof has lost its slope or is wavy or sunken in areas. If your roof is not pitched properly to divert water to the downspout or eaves, this is a major problem that should be addressed immediately.
