There are several signs that indicate you need to either replace or repair your modified bitumen roofing. One of the most common signs is when the roofing starts to leak. If you notice water spots on the ceilings or walls, it’s a sign that there is a problem with the roof. Another sign that it’s time for a new roof is when the roofing starts to curl and peel. If you see any of these signs, it’s time to call in a professional to take a look at your roof.
One of the more obvious signs that it is time to replace your roofing is when you start to see missing or broken shingles. Another sign that your roof might need replacing is when you notice rust stains on the exterior walls or foundation of your home. If there are any indentations in the attic, this also means it’s time for a new roof. It’s also time to replace your roof if there is evidence of mold and mildew on the insulation of the attic.
Here are a few signs that it may be time to call your local roofing repair specialist.
Worn Asphalt
When the modified roofing installation is done, asphalt Is used to hold the various layers of material together. Sometimes the asphalt wears away in a spot, exposing the protective layers below. This can allow moisture to seep through, and cause expensive water damage.
Slipping and Delaminating
Normal weather cycles of heating and cooling can cause the asphalt adhesive to delaminate. This can cause the individual membranes to slip, which can lead to seepage and moisture damage.
Tears, Holes and Cracks
Tears and holes can appear in your roofing due to normal weather cycles, damage from animals and birds, debris from storms, falling trees, and countless other sources.
Deterioration to Old Repairs
If you’ve had repairs done to your original modified roofing installation, you will want to check these periodically. Typically, the materials used to make repairs are not the same quality as the original materials. These patch jobs can deteriorate faster than the rest of the roof, leaving you exposed.
Loosening or Lifting Fasteners
Due to the natural expansion and contraction of the roofing material from heat and cold, it is not uncommon to find loosening or lifting fasteners. This can cause danger of sliding and falling shingles. Sometimes, when not checked frequently, fasteners can actually pop out altogether.
Debris and Pools of Moisture
Collected debris and pools of water can compromise the integrity of your bitumen roofing. Debris can block drains, allowing moisture to collect. This puts your roof at risk of structure failure.
Grease
If your property houses a restaurant with a roof vent, maintenance can be even more important. Grease can actually deteriorate some layers of the roofing membrane. Repairs will also be difficult, as most sealants will not adhere to a greasy surface. Equipment should be maintained and cleaned frequently to avoid problems.
Installation Errors
Errors during the modified roofing installation may not be obvious at first. As time goes by however, complications may occur that can only be caused by installer mistakes. Things like substandard materials used, missing supports, not enough sealant in some spots, improperly installed materials, and many other possibilities can rob your roof of useful years without the proper vigilance.
Modified bitumen roofing lasts up to 15 – 20 years. To prolong the life of your roof as much as possible, you should check it yourself at least once a year, preferably at the end of the winter season.
If you do find signs of damage, contact your local commercial roofing repair specialist for a professional inspection.
