Roof maintenance

Water sitting where it shouldn't is the enemy. Blocked gutters back water up under the shingle edge; debris in valleys does the same. Twice a year and after big storms is enough for most homes.

Ventilation is the invisible one. A hot, humid attic bakes shingles from underneath and shortens roof life well before the material's rated span. Fixr puts asphalt shingle life at 20–30 years — poor ventilation is a common reason a roof lands at the bottom of that range.

Be skeptical about rejuvenation coatings and sealants sold door-to-door. Manufacturer terms vary and some treatments can affect coverage on your existing materials, so check the actual product documentation for your roof before letting anyone apply anything to it.

Finally: maintenance does not rescue an expired roof. If yours is at the end of its life, money spent on upkeep is money you will spend again with the replacement.

How to choose

Clear gutters twice a year

Spring and fall, plus after storms. Overflowing gutters push water back under the roof edge and rot fascia.

Check flashing every inspection

Chimneys, valleys, skylights and wall junctions. Failed flashing is the most common source of leaks on otherwise sound roofs.

Look at your attic, not just your roof

Daylight through the deck, damp insulation, rusty nail tips and staining all show problems before they show on your ceiling.

Trim overhanging branches

They drop debris, hold moisture against the roof and give storms something to hit you with.

Be cautious with pressure washing

High-pressure washing strips granules from asphalt shingles and shortens their life. Use the gentlest method that works, or leave moss removal to someone who does it professionally.
