Keeping your commercial building’s roof in good condition maximizes its lifespan. Once it deteriorates, you will face expensive repairs and a complete roof replacement.

Thankfully, there are methods for extending the lifespan of your commercial roof and maintaining its excellent condition for many years to come. Here are some pointers to assist you in doing that.

Clean The Gutters

The gutter is one of the most important parts of a commercial roofing Seattle because it directs rainwater away from your building. If water pipes become clogged with sticks and leaves, water may not flow properly, harming your roofing materials.

In addition to clogging gutters, debris also facilitates the formation of ice dams during winter storms. Your roof may suffer serious harm, including leaks and deteriorating shingles.

Gutters and downspouts should be cleaned at least twice a year or after a heavy storm. This will prevent the buildup of accumulated gunk and keep them free from damaging pests.

Limit Debris

Limiting the quantity of debris your commercial roof is exposed to is one of the best things you can do. This will enable you to increase its lifespan and save money in the long run.

Aside from the obvious shingles and nails, it would help to consider the leaves, dirt, moss, and other debris that can impede proper water drainage and cause your roof to degrade prematurely.

Seal Flashings

Your commercial roof’s flashing is the membrane that keeps water from flowing into weak spots on your structure. These include the seams where shingles meet, around dormers and chimneys.

If the membrane is cracked or flaking, it won’t be able to do its job. Eventually, it must be replaced to prevent water from seeping into the building and causing major damage.

There are a lot of different sealants available that can be used to ensure that your commercial roof flashing is waterproof and doesn’t let water in. However, the best depends on the climate and the material you’re using.


Ensuring your industrial roof has enough ventilation is one of the best things you can do to extend its lifespan. By preventing moisture buildup and mold formation, which can affect the lifespan of your roof and HVAC systems, you can help keep your house or place of business cool.

Improper ventilation can lead to many issues, including roofing material deterioration and mold growth in the attic space. It can also cause snow to melt and freeze again on the eaves, leading to ice dams that can damage the structural integrity of your building.

The key is to ensure that your commercial roof is correctly ventilated year-round. Properly designed ventilation systems allow hot air and moisture to escape while keeping cold air in.

Avoid Drain Pipe Discharge

Whether your commercial roof is made of metal, concrete, or other types of materials, there are some things you can do to help it last longer. For one, keep it free of debris and clogs.

A clogged drain pipe can cause water to pool up on your roof, eventually causing damage. The first step to avoiding this problem is to inspect your roof drains and clear any discovered blockages regularly. This is especially important after storms or in the fall when trees are dropping their leaves.
