A roof system is a big investment for homeowners, and may represent a significant portion of construction costs.
It’s a roofer’s job to help the homeowner protect his or her investment by conducting thorough, careful maintenance on the roof on a regular basis. This can help ensure it’s being properly protected.
Read on to find a handy checklist of roofing maintenance tips that can help a roofer ensure they don’t miss any of the essentials during routine maintenance activities. If you’re a homeowner, this list will guide you on what to expect when you hire a professional to come perform routine maintenance on your roof.
What to expect from an asphalt roof
Asphalt is one of the most popular materials used in residential roofing. In fact, statistics suggest four out of every five U.S. homes uses asphalt shingles. They look good, they’re easy to accommodate on different building styles, and they hold up well against the elements.
What causes damage to a roof?
The average roof takes a lot of abuse over its lifetime – often more than other areas of the house. Some common examples include:

Why maintain a roof?
Even if there are no outward signs of obvious damage, every homeowner should ensure a professional regularly inspects and performs maintenance, where necessary, to a roof. Keeping it in healthy condition may protect the home. Maintenance is an investment that may pay major returns down the road.
Four Steps to Regular Roof Maintenance
A roofer can help a homeowner properly maintain his or her asphalt shingled roof by completing four basic steps twice a year – plus after major storms (including ice, hail, snow or rain storms; or other major weather events such as tornadoes and hurricanes).
Follow this roofing maintenance checklist
It’s important to also remind homeowners to always contact a licensed roofing contractor to help conduct both the inspection and repairs of their roof.
An important part of roof maintenance is the routine cleaning, clearing and tidying of the roof and its related systems.
Here’s what we recommend:
Working from the ground, homeowners should where possible regularly clear debris from the roof, including leaves, branches, and other items that may be cluttering the surface. Your roofer may use a leaf blower to do this, being sure to blow the air down the roof (so he’s not blowing debris up and underneath the shingles).
To reduce the amount of debris that gathers, cut away vegetation that may be hanging over the roof. (Hire a contractor to cut away difficult or hard to reach areas.)
Use a trowel to dig out leaves and organic matter from the gutters. This will help ensure water can drain cleanly through to the downspouts.
Homeowners may consider installing eavestrough protectors, which are metal meshed grates that prevent buildup of debris and make cleanup easier.
Ensure the down spouts are clear and flowing well so that water can drain properly from the roof and away from the home (and not leak or drip down the sides of the house). A homeowner can do this by taking notes of any leaks or drips that occur during or right after a rain storm and reporting those to his contractor during inspection time.
Once the roof has been cleared, the roofer should inspect it for any potential problems or red flags that could spell trouble down the road.
He should complete this inspection twice annually (we recommend spring and fall). This will give him the opportunity to make note of anything suspicious, as well as complete small fixes or minor repairs before they turn into big issues.
As a roofer, keeping a close eye on your client’s roof will help you become familiar with it, which gives you the advantage of knowing when something has changed – a key factor in catching problems early.

Also check for any evidence the ventilation system (intake or exhaust) is malfunctioning or may need maintenance or cleaning. (Some obvious hints may be condensation inside the attic or ice dams.)
A trained contract roofer should immediately complete asphalt shingle roof repairs to maintain the integrity of the roof’s materials and related systems (such as drainage and ventilation). Small fixes done properly can help prevent larger problems, or more major repairs, over time. He may:
Replace or repair missing, broken or buckled shingles: A roofer may use roofing cement and/or nails to repair shingles that have become cracked or loose. He may also replace any shingles that have broken free or blown away.
Replace Or Install Valley Flashing
A roofer may also consider replacing the existing valley flashing it if it has become corroded, cracked or is no longer holding in place – thereby threatening its waterproofing properties.
Replace Other Flashing
Your roofer may use roofing cement and nails to replace metal flashing around chimneys, roof vents or other installations if the flashing has become loose or rotten. If installing the flashing against brick, it’s advised to use copper or galvanized steel, because the lime in brick mortar may corrode aluminum.

Repair Gutters Or Downspouts
Your roofer may use gutter caulking, a gutter patching kit or roofing cement and patches to repair leaky or corroded sections of the eavestroughs or downspouts. If they are sagging, he will use a level to determine proper pitch and rehang them so they drain properly.
Owners of professional or industrial buildings often work with commercial roofing companies to maintain a formal record of roofing inspection and repair. This is an important aspect of maintenance and data collection, which helps support strong occupational health and safety practices.
Residential roofers could benefit from this same approach to their clients’ roofs in good shape. The following recommendations may also help a roofer give their clients a maintenance process that goes above and beyond the competition.
Keep A Log
A roofer should make a note of any potential problems he sees during a roof inspection (such as rust appearing on flashing, or a single popped nail). If it’s not a concern today, the roofer should check in on it during his next inspection and make a note if it’s getting worse. He may consider whether it’s time to make repairs or replacements if he notices consistent or major changes. The roofer should also make a log of any repairs he completes. This will help remind both the roofer and the homeowner down the road what sections or materials are newer than others. (After four or five years, it may be difficult to recall strictly from memory!) This will also help create a roof history for the homeowners, other roofing contractors they may hire down the road, or even for future homeowners who may want to see what work has been completed over the years to maintain the roof.
If it’s safe to do so, a roofer should take photos of the roof and its drainage systems. (Or, ask a colleague to safely assist.) These can give the roofer and the homeowner a baseline record against which to measure if a small problem appears to be getting worse. Or, if the roofer spots a change in the roof and isn’t sure what it means, he can email the photo to a fellow roofer to see if they think it warrants a repair.
Whether you’re a homeowner looking to maintain the life of your residential roof system, or a roofing professional educating your client on the benefits of regular inspection and repair, committing to a consistent schedule is like a well-constructed roof — well worth the investment.
