Roof Repair Desk is a library of 44 practical guides on repairs, replacement, metal, maintenance, and the exterior details that keep water out. Each one is written to help you tell a small fix from a real problem and know which jobs are yours and which need a licensed roofer.
Clear what you can from under the drip and put a bucket or bin down to catch the water.
Trapped water can bring a whole ceiling down. Poke a small hole at the center of the bulge with a screwdriver so it drains into your bucket.
Do not climb up to look. Wet shingles and steep pitches are how people get hurt, and the leak rarely enters right above the stain.
Shoot the stain, the drip, and any soaked belongings before you clean up. Dated photos are what an insurance claim runs on.
If you have to slow the water, tarp from within the attic where it is dry, or have a pro tarp the outside for you.
Move fast on the inside. Leave the roof itself to a pro.

Flashing is the metal that seals the joints where a roof meets something else: chimneys, walls, valleys, skylights, and vent pipes. Those transitions move, expand, and collect water more than an open field of shingles, so their sealant and metal wear out first. A cracked flashing joint or failed pipe boot lets water in even when every shingle looks fine. That is also why a leak often appears several feet from its true source, since water runs along the decking before it drips. A pro checks these details first.
Repeated repairs on a roof past 20 years old usually cost more over five years than a single replacement. Widespread granule loss, curling or missing shingles across large sections, sagging along the ridge, and repeated leaks in different spots all point to a system at the end of its life. Soft or water-stained decking is the clearest signal, since patching over compromised sheathing traps moisture. A licensed inspection gives you a straight answer on whether targeted repairs still buy useful time.
For a primary home roof, often yes. Standing seam hides its fasteners under raised seams, so there are no exposed screws and rubber washers to degrade and leak over time, which means less maintenance across the roof's life. Exposed-fastener corrugated panels cost less upfront and install faster, which suits outbuildings, porches, and tighter budgets, but the screws typically need re-tightening or replacement down the road. Standing seam is also the easiest metal surface for clamp-on solar. Weigh how long you plan to stay against the higher initial price.
Inspect twice a year, once in spring and once in fall, and again after any storm with high wind or hail. Roofs over 15 years old, homes under heavy tree cover, and flat or low-slope roofs benefit from a check every three to four months. Cleaning is driven by growth rather than the calendar: remove moss and algae as soon as you see it, since it lifts shingle tabs and holds moisture. Clear gutters and valleys of leaves and debris at least twice a year so water drains freely.
A flat or low-slope roof relies on a continuous membrane and careful drainage rather than gravity pulling water off quickly. Standing water, called ponding, is the main threat, so drains, scuppers, and slight tapered slopes have to stay clear and working. Seams and flashings are the usual leak points, and they need inspection more often than a steep roof. Foot traffic, rooftop equipment, and UV all wear the membrane over time, which is why coatings are common on these roofs. Treat drainage and seams as the priority.
Small issues like a loose hanger, one leaky joint, or a clogged run are repairs. Replacement makes sense when gutters sag along much of their length, when seams leak in multiple spots, when the metal is rusted through or cracked, or when they pull away from a rotted fascia. Aluminum gutters typically last 20 to 25 years and vinyl 10 to 15, so age matters too. If you are already patching several sections, a seamless replacement usually costs less over time than chasing leaks around an old system.
