Modified bitumen roofs offer durability and longevity, but like any roofing system, they need to be properly maintained to last. The durability of your re-fashioned bitumen roof primarily depends on how well you take care of it. Regular maintenance can help extend your roof’s lifespan, preventing costly replacements and breakdowns.

Here are some steps to help you extend the life of your bitumen roof.

1. Regularly Inspect Your Roof

Regular inspections are essential for keeping your re-fashioned bitumen roof in top shape. Check for loose, cracked, or missing shingles and any tears or holes in the membrane. Be sure to also look for signs of water damage, such as moss or algae growth and leaking around flashings or other seams. A roof installation contractor can help you identify problems and recommend the best action.

2. Trim Overhanging Branches

Tree branches that hang over the roof can scrape and puncture the bitumen membrane when they sway in the wind. This can lead to leaks, so it’s important to trim any overhanging branches to prevent damage. Try to keep branches at least 10 feet away from the roof. Modified bitumen roof maintenance can be easier if you start with a sturdy tree-trimming program.

3. Clean Debris From the Roof

Twigs, Leaves, and other debris can accumulate on your roof over time. These organic materials can trap moisture, leading to the growth of moss and algae. It’s significant to clean debris off your roof routinely. A leaf blower can help with this, but use it on the lowest setting, so you don’t damage the bitumen membrane.

4. Repair Small Damage Immediately

If you find small tears or punctures in your bitumen membrane, it’s vital to repair them immediately. Using a bitumen patching compound, apply the material over the damaged area and allow it to dry. The lifespan of your reshaped bitumen roof will be greatly extended by taking care of small problems before they become bigger issues. With the help of a roof installation contractor, you can confidently repair any small damage on your bitumen roof.

5. Reseal Seams and Joints

Over time, the sealant applied to your roof’s seams, and joints can dry out, crack, and wear away. Check for seams that need to be resealed and apply the appropriate material. This will help maintain a waterproof seal around flashings, vents, and other connections. Modified bitumen roofing installation professionals can help inspect and reseal these areas if you are uncomfortable doing it yourself.

6. Apply a Protective Coating

Adding a protective coating to your bitumen roof can help extend its lifespan by keeping water, dirt, and UV rays from damaging the membrane. Look for a waterproof coating such as silicone elastomeric, which creates a rubber-like seal that adheres to your roof. It’s important to check with a roofing professional before applying any coating, as some can be too heavy for certain roofs.
