What does an inspection check that a leak repair does not?
A leak repair looks at the spot where water appeared. An inspection looks at the whole roof as a system, so the cause is found even when it is some distance from the stain.
A leak repair starts from a stain, and it is aimed at the most likely opening. An inspection starts from the roof and asks what else is in the same condition.
The inspection also covers the parts a leak repair never reaches: the decking underneath, the attic ventilation, the drainage and the eave. Those affect how the roof behaves in winter and how it will behave in the next storm, and they are the reasons a roof can keep leaking after a repair that looked complete.
How does an inspector tell repair from replacement?
The decision turns on how widespread the problems are, what the decking looks like once it is seen, and whether the covering is still doing its job across most of the roof. A single failed area usually points toward repair, and widespread failure points toward replacement.
Where the covering is worn across most of the roof, with granule loss, curling and nail problems in many places, repair becomes a series of patches that does not change the outcome. Where the damage is confined to a few planes, a targeted repair can carry the roof for a longer period.
The decking is the deciding view. Soft or stained decking under the covering changes the answer, because the deck is the structure the covering is fixed to. The report describes what was seen when the covering was lifted, and it lays out the options with the reasons for each.
Why does attic ventilation appear in a roof report?
Ventilation and air sealing are part of how a roof behaves in winter. Heat that escapes from the attic is what melts snow on the roof, so the attic is part of the roof's condition and not a separate matter.
The sourced guidance on ice dams says that the most effective fix is controlling the air that leaks outward into the attic, and that the ceiling should be made airtight before anything else. Minnesota Extension cautions that mechanical attic ventilation is not a solution to ice dams on its own, and it can create moisture problems if it is added in the wrong place.
Wet insulation is also noted. The sourced guidance says water-soaked insulation stays compressed and thinner after it dries, so its performance is lost for good. An inspection flags that in the attic, because it is evidence of an ice dam that has already run.
How does an inspection differ on a multifamily building?
On a multifamily building the roof is a shared asset, and the person who signs for the work may be the owner, a landlord, a board or a managing agent. The report is written so that the decision-maker can act on it without the roof being opened twice.
Access is planned before the inspection. The roof may be reached through a building's own hatch or a shared stair, and the drive, the lot and any neighboring structures determine where a ladder or lift can stand.
The Stamford stock includes dense multifamily buildings, condominium associations and small landlord-owned blocks, and the inspection notes which of those applies. Where a board is the decision-maker, the report is set out so that it can be read at a meeting, with each item and its timing clearly stated.
What moves the price of an inspection up or down?
The price of an inspection depends on the size and pitch of the roof, the access, the number of roof planes and layers, and whether the building is multifamily. It is explained and approved before the inspection starts, and no figure is given here.
A small roof on a single-storey house with clear access is a short inspection. A large roof with several planes, slate or tile, and a flat section takes longer to walk and to record.
A report that has to cover several buildings, or that will be read at a board meeting, takes more care in the writing. The technician says what the report will include before the inspection starts, so the scope is clear, and no added work begins without the owner's approval.
