What does a roof inspection include?
An inspection covers the covering, the decking under it, the flashing at every penetration and junction, the ventilation and insulation in the attic, and the gutters and fascia at the eave. It ends in a written report.
The covering is the layer the homeowner sees, and it is judged on its own condition: granule loss, curling, cracking, lifted tabs and the state of the nails that hold it. The decking under it is judged from the attic. Plank decking common in older houses and modern sheathing behave differently when they are wet, and a report that does not look at the underside of the decking misses half of what matters.
Is an inspection the same as a repair estimate?
No. An inspection describes the roof's condition. A repair scope sets out the work to fix it, and a price is explained and approved separately, once the scope is known.
Many homeowners ask for an inspection and expect to leave with a number. The inspection is the step that makes a repair scope possible, because the scope depends on what was found in the decking, the flashing and the attic. A roof with a single failing penetration needs a different scope from one with soft decking across several slopes, and the inspection is what tells them apart.
How is remaining life judged without a number?
Remaining life is judged from the roof itself: granule loss, curling, nail condition and the decking. The one exception is slate, where the National Park Service gives a sourced range for the slates common in the late 1800s and early 1900s.
For asphalt shingles, cedar and metal, no lifespan in years is printed here, because the figures available came from commercial quote sites and cannot be published. A technician judges the remaining life from what is seen: granules washing into the gutters, shingles curling or cracking, nails that have backed out or rusted, and decking that is soft or stained. Those signs describe the roof's condition directly, and they are more useful than an age.
What moves the price of an inspection here?
The height of the building, the number of roof planes and units, the access to each attic, the condition of the roof and whether a lift is needed decide the price of an inspection. No figure is printed here, and the price is explained before the visit is booked.
A single-family house with one attic and a simple roof is quick to inspect. A three-story multi-family building with several roof planes and a unit attic to reach on each floor takes longer and needs more coordination. Height and access matter as well, since a steep roof or a tight side yard can change the equipment needed. Each of these is named when the visit is arranged.
Do I need a permit to have a roof inspected?
An inspection does not start construction, so the permit question arises only when work is proposed. The city's Building Division decides what any proposed work needs.
Building permits have to be obtained before construction begins, and an inspection is an assessment rather than construction. When the report leads to work, the permit question comes up for that work, whether it is a flashing repair, a covering replacement or a structural change. The Building Division, part of Code Enforcement, sets the requirement for each proposed job and the review period for a complete application.
