Best Practices for Preventative Maintenance

With the weather cooling, now is a great time to perform preventative maintenance on your roof. Simply checking and cleaning your roof can solve many problems before they occur. Roofs take a lot of elemental abuse during the year. Simple steps can provide a longer service life for your roof and save you money.
Built-up and modified bitumen roofs:
  • Clean and remove all debris from the roof surface. Be sure to get under and behind HVAC units, pipes, curbs, skylights, and any other penetrations. Debris, especially organic matter like fallen leaves, tends to hold water. On asphalt based roofs like built-up and modified bitumen, extended exposure to water or moisture will deteriorate the roofing surface leading to potential leaks and “alligatoring” of the roofing surface.
  • Check all flashings for deterioration, damage, and cracks. Also, check the caulking and sealant for deterioration. Any flashings found to be cracked or weather damaged should be repaired or replaced. Pitch pans should be refilled.
  • Make sure that the edging material is not showing signs of separation at the seams and/or wind damage.
  • Look for blisters in the roofing surface. Do not puncture the blisters.
  • Check the gutters. Clean out if needed. Check the downspouts by pouring water into the gutter above them. Clean out downspouts if needed.
  • Any tree branches hanging over your roof should be trimmed back.
  • Check mortar on parapet walls, coping cap(s), and terracotta caps. Any damage or deterioration should be repaired.
PVC and other single-ply membrane roofs:
  • Clean and remove all debris from the roof surface. Be certain to remove all loose nails, screws, and organic matter.
  • Review seams.
  • Check all flashings for excessive deterioration, bridging, and damage.
  • Edge metal needs to be checked for separation at the seams, and wind damage.
  • Check for cuts or cracks in the roofing surface.
  • Remove debris from gutters and check downspouts.
  • Any tree branches hanging over the roof should be trimmed back.
  • Check parapet walls and caps for deterioration and damage.
Metal roofs:
  • Clean and remove all debris from the roof surface. Be certain to remove all organic matter (leaves and dirt, especially, as they can hold moisture).
  • Check screws and fasteners. These may become loose due to the natural expansion and contraction of the metal roof.
  • Look for signs of rust and deterioration.
  • Cut back any tree branches that overhang the roof.
  • Remove debris from gutters and downspouts.
  • Check parapet walls for signs of damage or deterioration.
