Whether you enjoy a metal roof protecting your private home or major business, you have made a substantial investment in one of the strongest, most durable roofing solutions available. Protect your investment. Keep your metal roof clean with these tips.
A metal roof on a residence or business needs very little upkeep. An annual cleaning to remove debris, dirt, and grime is usually enough.
No residential homeowner should risk going on a home’s roof; leave that work to professional roofers who have the proper safety equipment.
For commercial properties with metal roofing, a facilities crew can clean the roof effectively with ordinary tri-sodium phosphate (TSP) diluted in water as needed. Using long-handled scrub brushes and TSP, a crew can remove dirt and grime, attack algae and incipient mold, and leave behind a gleaming roof.
Most roofers advise against pressure washing due to the risk of forcing water under seams, into the roof deck itself. This can lead to water infiltration, along with the possibility of mold and mildew inside the building.
After cleaning, an inspection can help head off any issues with loose or missing mechanical fasteners and other potential problem spots:
- Corroded areas — These may require work with a wire brush and then touch-up with primer, paint, and sealant
- Places where unlike materials meet, such as HVAC curbs or chimneys
Metal roofs enjoy some of the longest warranties and lifespans in the roofing industry. The 50-year warranties are often more effective on the paint than on the metal, which (realistically) may last a century. The paint and finish is the “weak” spot, and even those are part of most 50-year warranties!
Both residential and commercial owners who have metal roofs should seek professional guidance on touching up a metal roof’s finish. To preserve the warranty, the job must be done in accordance with manufacturer’s directions. It usually involves more than just a can of spray paint:
If you try a do-it-yourself approach, sun fading can make the freshly applied paint age faster than the baked-on roof finish, leaving an irregular, blotchy roof.
