Your building probably came with a roof when you purchased it. Maybe you thought that was the end of the story as far as your roofing needs went, except, perhaps, for accidents like falling trees. However, roofs need to be inspected, maintained, repaired and replaced. The average life span of a shingled roof is 10-45 years, depending on materials, with 20-25 years being the life expectancy of the most common types. Other maintenance is required in between. Thorough inspections and minor repairs can be scheduled on a regular basis, preferably in spring and fall, but at least once a year. The National Roofing Contractors Association in the US says that roof maintenance is the single most important factor in roof system life span and cost savings.
A roof system has many parts, from the supporting skeleton, or truss, to the underlayment over the truss protecting against moisture, the decking material that shingles attach to, the shingles themselves, the flashing - strips of metal to prevent moisture seepage where things like chimneys protrude and join the roof, as well as fascia, drip edges, and other components.
Problems caused by lack of roof maintenance include:
- Leaks. These are common and costly. They can be difficult to fix because water moves and the source of the leak may not line up over the wet area. Roofing professionals are your best bet here because this can be quite an investigation.
- Water damage, mold and rot, from leaks and other failings of the roof system.
- Poor insulation of your home, making it difficult to maintain a comfortable temperature in either winter or summer.
- High winds can remove even well-maintained shingles. Shingles in poor condition are much more likely to be blown off, leaving the decking vulnerable to all kinds of damage.
Signs you may need roof maintenance:
- Water dripping or other signs of moisture, such as wall and ceiling stains inside your house - particularly after a heavy rain.
- Blistering and peeling of exterior paint.
- Your shingles are more than 20 years old.
- Decay of roof shingles, sheathing or siding under the roof decking, showing a crumbled and ripped appearance.
- Discoloured shingles.
- Missing, cracked, or curling shingles.
- Shingles found in the yard.
- Granules in your gutters. These granules are part of the protective materials of your shingles. Another sign they have worn off is smooth, dark, shiny shingles.
- Parts of your exterior walls near the roof appear darkened, as if wet.
- Discolouration on interior walls near the ceiling.
- Your utility bills are rising, during both heating and air conditioning seasons.
Note: Rather than get up on a ladder yourself to check for these signs, use binoculars. Better yet, call your ottawa roofing professional for an inspection.
Types of roof maintenance:
Note: Due to safety concerns, contact a professional roofing contractor to do this work.
- Roof Inspection for:
- general health of shingles, fascia, gutters and fixtures;
- hazardous debris which can cause damage, gutter clogs, and fires;
- broken, shifting or sagging structures;
- water pooling; rust and leakage;
- lifted or rusted flashings and drip edges.
- Leaks: First, other non-roof causes of moisture need to be ruled out such as plumbing, ventilation, and animals. (See our blog on attic ventilation maintenance for more information). Then, flashings and sealants are checked and repaired around things that penetrate the roof, like chimneys, skylights, plumbing vents and satellite/cable attachments. Drip edges, dormers, and roof-to-wall transitions are also checked.
- Shingle repair and replacement.
- Repair and replacement of underlying roof structures and parts.
- Roof ice and snow removal.
