Preventative Maintenance Programs & Service Repairs


Extend the life of your roof.

Preventative maintenance is a routine, professional upkeep program intended to eliminate premature roof damage and extend the life of your roof over time. An effective preventative maintenance strategy will extend your roof’s life cycle.

Roof maintenance doesn’t end at the roof membrane level. Accessories such as photovoltaic solar panels, coatings, skylights and light tubes all require regular maintenance in order for them to continue providing their energy-efficient return on investment.

Preventative Maintenance Programs and housekeeping are often required in order to meet the requirements of many long-term warranties.

What does our Preventative Roof Maintenance Program include?

Our experienced service crews follow an inspection checklist of over 50 items related to your roofing system. These items include: documenting defects, points of deterioration and compromised roof accessories and assemblies.

After the checklist is completed, our experts create a customized preventative maintenance recommendation for your roof. This includes a detailed written assessment with photographs and repair or replacement solutions.

Common recommendations include:

  • Debris removal

  • Clear drains for proper water flow

  • Caulk terminations and pipe seals as needed

  • Repair roof surface defects, water-entry points and damage

  • Upgrade or add safety accessories to remain OSHA compliant.

Do I have to have a Preferred Roof Services roof to get a Preventative Maintenance Program?

No! We offer Preventative Maintenance Programs for any and every commercial roof from any installer.


Consumer Guidelines For Roof Care & Maintenance


Shingle Roofs

• Light colored shingles reflect heat; dark shingles absorb heat.

• Select products supported by a warranty

• Fungi often cause roof discolorations that can be mistaken for soot, dirt, moss or tree debris. Since fungus does not feed on the roofing materials it does not affect the service life of the roof. (Moss will restrict water flow and hold moisture)

• Replace missing or broken shingles. Check for loose or missing nails.

• Patched of grey or black often show where ceramic surface granules have worn off.

• Missing ridge and hip shingles on gable or hip roofs should be immediately replaced to prevent leaks.

• Leaves and debris in gutters means poor drainage and can force water up under shingles. Avoid the problem by flushing out gutters and downspouts at least twice per year.

Built-Up Roofs

Most homes with built-up roofs are either smooth ­surface or gravel-surface types. Defects are highly visible and can usually be repaired quickly on smooth-surface roofs. Gravel-surface roofs add a weather protective layer to your roof.

• Standing water on your roof usually indicates improper drainage and may cause leaks, erosion or some other form of deterioration.

• If a gravel-surface roof has been improperly applied, the gravel may be washed or blown away. If the felt-layer is exposed, check to see if the felts have split or have become dry and brittle. When this happens the bitumen (asphalt) between the felts deteriorates.

A smooth-surface built-up roof may bleach in the sun. If a scrape test shows live black bitumen underneath, there is little need for immediate concern. However, if the felts are dry and brittle, re-roofing may be indicated.

Other problem indicators are blisters, wrinkling or ridging, or openings where the felt has lifted and cracked.

The old adage "an ounce of prevention is worth a pound of cure" is most aptly applied to the sub­ject of roof care and maintenance. The following consumer guidelines have been prepared by the Roofing Contractors Association of Washington to assist home owners in the care of their roofs. This pamphlet describes general roofing care and outlines preventative maintenance that may help prolong the life of your roof.

The major damage to a roof is caused by weather and the elements, improper drainage and deteri­orating materials. You may significantly increase the life of your roof and avoid costly repairs by following a maintenance program.


• Inspect gutters, drains and the roof at least twice per year. Clean and remove all debris from roof drains. Keep the roof surface clear of all litter such as leaves, twigs, pine needles, and branches so that water can drain properly. Late fall and spring are excellent times to clean your roof.

To eliminate extra roof traffic always check chimneys during regular roof inspections.

• Inspect roof, gutters, ad drains after unusually heavy rains, ice, snow, and wind storms. Do Not inspect your roof during extreme cold and heat conditions.

• During roof inspections check attic and joist ventilation to ensure you have adequate venting to eliminate condensation indicated by moisture or mildew.

• It is recommended homeowners obtain a periodic professional roof inspection usually every three to five years by a competent roofing contractor. When requesting a roof inspection avoid the contractor's busy season of May thru September and immediately following a heavy storm. Frequency of inspection should be determined by the age of the -roof, how it is used, and weather conditions.


• Consider roofing repair work in light of the age and type of roof. Different types of roofs have different life spans. A roof less than two years old usually only needs maintenance; around ten years more extensive work maybe indicated; from 15 years on a new roof may be in order.

• Fix minor repairs before they become major problems.

• Minimize foot traffic on your roof.

• Unless experienced, do not attempt to attach guy lines or antennas to your roof. Consult a roofing contractor for service or advice.

• Be sure proper flashing and/or sealing proce­dures are followed whenever anything new is added to the roof such as sky lights, vents, chimneys, etc.

• If you discover leaks or other problems after a storm, make a note of the weather conditions for the repair person.

• To protect property loss, patch leaks in emergency situations. In non-emergency situations be wary of "instant cures and miracle products:' Owner performed roof repair may cover up evidence the roofing contractor needs to discover 􀁌he source of the problem.

• Repair work will usually fall into one of three categories: spot patching, coating and

re-roofing. If a contractor suggests something else, get a second opinion.

• If a reputable roofing contractor recommends a new roof-follow that advice. Consider your roof on a cost per year basis; temporary measures in roofing are usually most unsatisfactory to all concerned. The soundness of the roof decking and supports should , also be checked for damage prior to the re­roofing. Should the deck supports or roof itself be warped, rotten or unsound, remove the old roofing to allow structural repairs.

• Always make sure adequate ventilation is provided for in any re-roofing situation.

• Roof coatings are a preventative measure recommended if there are no leaks or extensive damage. They are effective when applied correctly before the roof membrane weakens through deterioration.

• Coatings, applied by brush, roller or spray apparatus, vary according to the type of roof, climate and drainage.

• Maintain a roof file and include such information as roof plans and specifications, maintenance schedule, roof age and warranty, materials used, dates and contractors name and phone number.
