1) Membrane Issues

Blisters and loss of granules can plague flat roofs and expose the roof to leaks, while holes and punctures provide a path for water to enter your building. Examine the roof for signs of any of these problems – if weathering has degraded the roof surface, it’s better to know now than later, when melting snow starts leaking into your facility.

2) Blocked Drains

Fall leaves and other debris can clog the drain on your roof, creating areas of standing water that can pose a problem for your roof. Keep drains free of blockages.

3) Shingle Degradation

If you have a sloped roof with shingles, check the shingles regularly to see if they’re warped or even missing. Asphalt shingles may lose granules, indicating a need for replacement, while tiles and slates may be chipped, cracked or broken. Check wood shingles for moss, mold and mildew. Metal roofs are vulnerable to corrosion.

4) Flashings and Penetrations

Any area that requires a break in the roof’s membrane, such as pitch pockets, skylights and vent pipes, presents an opportunity for leaks to develop, so be sure to check every possibility.

5) The Interior

No roof inspection is complete without a review of ceilings and interior walls for signs of leaks and staining.
