Question 1

Is the leak active right now?

Accepted Answer

Active leaks during rain are emergencies and may cost more. If water is coming through the ceiling, place buckets and towels, then call immediately. If it's dry now, schedule a non-emergency inspection — it's cheaper.

Question 2

How old is your roof?

Accepted Answer

Asphalt shingles last 20–30 years, metal 40–70, tile 50+. If your roof is near the end of its life, a roofer may recommend replacement over repair. Knowing the age saves time on the initial call.

Question 3

Can you see the damage from the ground?

Accepted Answer

Missing shingles, sagging spots, or visible flashing damage all help the roofer plan before climbing up. Take photos from the ground and send them ahead — never climb the roof yourself.

Question 4

Do you have attic access?

Accepted Answer

Roofers often inspect from inside the attic to trace leaks. Let them know if access is easy, tight, or blocked by insulation or storage. Clearing a path beforehand speeds up the visit.

Question 5

Has anyone else already looked at it?

Accepted Answer

If a previous contractor gave an estimate or did partial work, share that with the new roofer. It avoids duplicating inspection work and helps them understand the repair history.

Question 8

What is a Ice dam?

Accepted Answer

A ridge of ice that forms at the roof edge and blocks melting snow from draining. Water backs up under shingles and can cause leaks. Proper insulation, ventilation, or heat cables help prevent ice dams.

Question 9

What is a Shingle granule loss?

Accepted Answer

Shingle granule loss is the erosion or shedding of the protective mineral granules that coat the surface of asphalt shingles. These granules — made from crushed rock, minerals, and ceramic particles colored with pigments — serve three critical functions: they shield the underlying asphalt from ultraviolet radiation (which would rapidly break down the petroleum-based binder), provide fire resistance (Class A–rated granules withstand flame spread), and give the shingle its color and aesthetic appeal. Some granules are lost during manufacturing and shipping (which is normal in the first year), but progressive loss over time indicates weathering and aging. Accelerated granule loss is caused by hail impact, heavy rain, foot traffic on the roof, power-washing (never recommended for asphalt roofs), poor attic ventilation causing excessive heat buildup, and manufacturing defects. The most visible warning sign is accumulation of granules in gutters and at the base of downspouts — the material looks like coarse black or colored sand. Bare or bald spots on shingles where the dark asphalt substrate is exposed confirm significant loss. Once granules are gone, UV degradation accelerates rapidly: shingles curl, crack, and become brittle, reducing remaining roof life from years to months. Granule loss does not typically warrant spot repairs because it indicates systemic aging; however, if limited to a small area after isolated storm damage, those shingles can be replaced individually ($150–$400 per area). Widespread granule loss across the roof means the shingles have reached the end of their effective life and a full roof replacement ($8,000–$25,000 for a typical residential roof) should be planned within 1–3 years. Insurance may cover storm-related granule loss if documented with photos and a professional inspection within the policy's filing period.

Question 10

What is a Roof valley?

Accepted Answer

A roof valley is the V-shaped channel formed where two sloping roof planes meet at an internal angle. Valleys are high-traffic zones for water runoff — rain and snowmelt from both roof planes funnel into the valley, making it one of the most leak-prone areas on any roof. Valleys are protected by metal flashing (open valley) or by overlapping shingles (closed or woven valley). Open valleys use W-shaped metal flashing visible between the shingles and are considered more durable and easier to repair. Closed valleys weave or cut shingles across the valley for a cleaner look but can trap debris. Valley flashing failures, ice dams in valleys, and debris buildup are common causes of roof leaks. Professional valley repair or reflashing costs $400–$1,500 depending on length, material, and roof pitch. During a roof replacement, valley treatment is one of the most critical details that separates quality work from shortcuts.

Question 11

What is a Chimney flue liner?

Accepted Answer

A chimney flue liner is the protective channel that runs the full height of a chimney, containing combustion gases and directing them safely outside. Three main types are used: clay tile liners (the traditional choice in masonry chimneys, durable but prone to cracking from thermal shock), metal liners (stainless steel, used for retrofits and gas appliances, durable for 15–25 years), and cast-in-place cement liners (poured to coat the existing flue, a permanent solution for older chimneys). Without a working liner, hot gases and creosote can reach the brick and mortar, accelerating deterioration and creating a serious fire hazard. The CSIA recommends an annual chimney inspection — Level 2 inspections include a video scan of the liner. Common failures include cracked tile liners, gaps at joints, blockages from animal nests or fallen masonry, and corrosion in metal liners. Relining a chimney with stainless steel typically costs $2,500–$5,000; a clay tile reline can run $4,000–$10,000. Always hire a certified chimney sweep, not a general handyman, for liner work — improper installation can void homeowners insurance and create life-threatening carbon monoxide risks.
