Roof preparation for winter starts with a few practical priorities: identify existing damage, make sure water can drain, and have vulnerable flashing and roof penetrations checked. Finish necessary repairs before freezing weather makes access and scheduling more difficult. A roof does not have to look badly damaged to need attention. A loose shingle, a deteriorated pipe boot, or debris collected at a flat-roof outlet can be easy to overlook during dry weather. Winter rain or melting snow may reveal the problem indoors. This guide explains what you can observe safely, what to ask a roofing contractor to inspect, and which findings deserve prompt attention. Why winter roof preparation matters in New Mexico Winter weather varies considerably across the state. The National Weather Service’s New Mexico winter weather guidance describes how mild conditions in the Rio Grande Valley can coincide with severe winter weather elsewhere. A mountain home and a lower-elevation property need preparation suited to their actual exposure. Where temperatures move above and below freezing, water caught in vulnerable openings can freeze and thaw. Roofing materials also expand and contract as temperatures change, even without freezing water. These are different processes, but both make the condition of seams, connections, and existing repairs worth checking. Plan roof preparation for winter around your location, roof type, and repair history. Start early enough to investigate problems and complete repairs before your area’s first sustained winter weather, rather than waiting for a particular calendar date. Start with a winter roof inspection Begin outside from ground level. Walk around the home and use binoculars or your phone’s zoom to examine visible roof areas. Look for missing or displaced shingles, broken tiles, hanging gutters, and branches resting on the roof. Then check inside. Note any new ceiling stains, peeling paint, or damp areas. If an old stain has changed since the last storm, photograph it and record the date. Tell the contractor about previous leaks and repairs, including problems that seem to have stopped. These observations help guide a winter roof inspection, but they cannot confirm the condition of hidden layers or a roof surface you cannot see. GAF’s homeowner maintenance guidance recommends inspecting shingles from the ground and leaving roof-level flashing inspections to a professional. Ask for photographs and a written explanation of findings. A useful inspection should distinguish an active defect from routine maintenance and explain what needs attention first. Address roof damage before winter arrives Have visible damage assessed while there is time to plan a suitable repair. On shingle roofs, that includes missing, cracked, or displaced shingles. On tile roofs, broken or shifted tiles warrant attention. On membrane roofs, a contractor should check punctures, separating seams, and damaged details. Do not assume that every defect requires replacement. Equally, a roof that has received several patches needs more than another layer of material over the same spot without investigating why it keeps leaking. Ask three questions when discussing roof damage before winter: The answer should determine the work. Avoid choosing a generic sealant or coating simply because its packaging mentions roof leaks. Compatibility, surface condition, and installation requirements matter. Clear gutters and check the full drainage route Water needs a clear route off the roof. On a pitched roof, that may involve valleys, gutters, and downspouts. On a flat or low-slope roof, drainage may depend on roof drains, scuppers, gutters, or a combination of outlets. A scupper is an opening through a parapet wall that allows roof water to discharge. Leaves, twigs, and accumulated debris can obstruct it, even when the rest of the roof looks relatively clean. Have the drainage route checked from the roof surface to the discharge point. An apparently clear gutter does not establish that its downspout is open or that the gutter drains properly. Carlisle’s fall maintenance checklist includes checking drainage performance and evidence of ponding near low points. If water repeatedly remains in the same area, report the pattern. Clearing debris may help, but a persistent drainage problem can require assessment of the slope or outlet arrangement. Arrange professional cleaning where access requires a ladder or roof entry. Never climb onto a wet, snowy, or icy roof to clear an outlet. Have roof flashing and penetrations checked The roof covering is only part of the system. Flashing helps manage water at intersections, edges, and openings. Roof penetrations, such as plumbing vents and skylights, need details suited to the surrounding roof material. Ask the contractor to inspect the relevant areas on your home: The inspection should look for separation, damaged components, loose attachments, and deteriorated seals where sealant forms part of the specified detail. A bead of caulk across a visible gap may leave the underlying problem unresolved. Include these details in roof preparation for winter even if the main roof surface appears sound. Water can enter at an opening without widespread damage to the surrounding roof covering. Give flat and low-slope roofs extra attention A roof described as flat still needs a way to move water toward its outlets. Before winter, ask for drainage, membrane seams, parapet transitions, and penetrations to be reviewed together. Carlisle’s care and maintenance guidance identifies roof edges, penetrations, equipment areas, and the membrane surface as inspection priorities for its systems. Your contractor should follow the instructions for your roof’s actual materials. Mention any recent work on rooftop equipment. Service visits can disturb nearby roofing, and the inspection should include those areas.

The seasonal priority is to understand the current defect and agree on a suitable response before the next storm. Check indoors for signs of water intrusion An indoor stain is a reason to investigate, not proof of a roof leak. Plumbing, condensation, and other moisture sources can produce similar symptoms. Record when the problem appears. Does it follow rain, occur during snowmelt, or persist in dry weather? Note whether it is close to a bathroom, a vent, or a
