A roofing inspector should look for signs of sagging roofs and uneven roof planes, as well as inspect the condition of the fascia, soffit, and gutter system. The contractor should inspect the masonry chimneys at this time to look for crumbling grout, cracks, and deterioration to the chimney caps.


The roofing inspector should also look for venting in the attic. Inappropriate venting can cause moisture and heat build-up that decreases the roof lifespan and expands the chance of ice barriers forming at the edge of your roof.


Workmanship Inspection by the Roofing Company

An experienced inspector should review your roof for issues in workmanship that may expand the risks of leakage or other roof deterioration in the future.


Faulty flashing around the roof penetrations—containing skylights, chimneys, and vent pipes—will all be dangerous if left untreated.

The interior inspection is needed because leaky roofs will damage the interior of your home. Thus, the inspector should check the interior ceilings, interior walls, and the attic looking for signs of mold, water stains, rot, and other signs that moisture is making its route into your home.


Check for Ponding Water

The inspector should look for signs of ponding water by assessing slow-draining areas and lines that are clogged. There might be discolored stains or changes on the roof near drains where water has sat. This inspection will identify if any underlying deterioration has been generated because of standing water.


Check the Ground for Tears or Cracks

A comprehensive commercial assessment of the roof ground will identify indications of tears or cuts in your roofing design that will need to be located before structural deterioration is incurred. If the inspector feels there's an existing leakage in the ground but is unable to identify it immediately, a “flood test” can be done for tracking down any deterioration.


Check for Flashing

The contractor should look at the flashing details such as walls, curbs, and stacks. Their purpose is to discover any crevices or cracks that can be repaired before the Winter comes around.


Cracks, as well as other damages are more common near transition points. This is especially frequent in places where the flashing goes from flat to vertical as there is more stress on these areas of the building. If any flashing problems are identified it is best to get it fixed before the weather cools down.


Check Terminations in the Parapet Walls

Cracks in parapet walls.

The inspector should check the terminations on the parapet walls; these must be adequately sealed. Your professional inspector should check the wall's base to see if there are any indications of cracking or damage. Make sure these problems are addressed to control much more extensive deterioration down the line.


Inspect the Gutters

Drains and gutters can play a vital role in ponding water and will need to be inspected.

If your gutters are blocked, water will be likely pool on the roof.


Although ponding water on PVC (Polyvinyl chloride) roof membranes won't void your guarantee and there is less potential for deterioration to occur, it's still not advised to be left untreated. On other types of roofs, particularly those that are asphalt-based, ponding water can immediately cause roof damage, especially throughout the Winter season. To stop this from occurring, remove any residue that has been collected in your gutters.


Inspect Edge Details

Roof edge details.

Your roofing inspection should include looking at the edge details of the roof. Roof edge materials must be tied down tightly. If they are not tied done tightly, a detailed inspection will be needed to adequately confirm if anything coming loose to seal gaps will let elements inside.


BOTTOM LINE

After the assessment, the inspector should offer a thorough report regarding the condition of the roof as well as what repairs, if any, are required to keep the roof in good shape.


If repairs are required, schedule them ASAP—before Winter. Thus, when snow falls, homeowners can feel comfortable that their roof is in good condition.
